We no longer have a broad reservoir/cadre/pool of practitioners of engineers, construction crews, experts, designers (except for a very concentrated few) who do this week in, week out. Every job now seems custom. Only Parsons or whoever has the ability to do it, and even they have to scrounge around for the project manager.
Other countries are in their building phase and have thousands of engineers who are practiced in standardizing designs and squeezing out inefficiencies. They have graduating classes full of highway engineers. For gods sake, they even have graduating classes full of engineers specializing in the tooling for highway / railroad engineering machinery.
Our building phase was post-war construction-crazy economic expansion era. Now we're in the maintenance phase, where big new projects are the exception. Not to denigrate the great importance of doing great maintenance, but in practice you can't keep (or attract) a large pool of well paid expert engineers going on that level of activity. They go where the projects go.
And as a result, as the report points out, when everything is "for the first time again" and custom because you do it once per decade, the particular factors of a given site are allowed to dictate what the system design should be. (Maybe also not insignificant: the environmental considerations allowed to creep in, just to point that out, as grateful as I am for the protection that we give these matters). Rather than (for better or worse, probably a bit worse) in other countries, they're stamping out highways, railroad, power plants by the week, and the environment is made to fit the construction.
It's choices we made, over time, that caused us to atrophy our capabilities here. It could be brought back with investment.
I would welcome some case studies from the commentors here, because "reasons" given in comments are not explaining what I have seen with my own eyes.
I agree with your entire comment, but I want to emphasize the part about illegal labor.
There are entire industries built on the back of illegal labor, and I think many otherwise informed Americans are not aware of this.
We have some fairly substantial mismatches between our labor market and our immigration policies.
Before someone says “just don’t use illegal labor”, please realize that this means that you will be out of business due to a lack of competitiveness since literally everyone else in your line of business does it.
Personally, I have mixed feelings about this. On the one hand, maybe it’s just better off staying like it is — the market is clearing. On the other hand, I kind of wish proper enforcement of the laws would happen. This would force these companies to pay wages that legal workers would take. This, of course, would require them to raise their prices to the end user, but it would give legal laborers more... of something... definitely money, definitely rights, and maybe a bigger piece of the pie.
I don’t work in any of these fields, but I know people who do. I would love to hear from HNers who have first hand experience.
Indeed. The game though, is a big reason for hiring people illegally is to keep costs down. Because illegal workers area afraid to complain and will work for less.
Now, when the average moron finds that there are lots of illegals in industry X, or in the country as a whole, they get up in arms about the illegals, support a crackdown but the crackdown doesn't remove the illegals but makes them more afraid, reinforcing the whole system. So the typical ideology of this country makes accomplices of people to the racket when sun light is (selectively) shed on the situation.
It's funny that China runs their on the same legal/illegal division of labor but in China the "illegals" are internal to China, people from the countryside who don't have official permission to be in the city.
One can imagine the several decades of law enforcement that would be required to change this situation, but it is an open question whether it would be a good thing overall.
It also has to do with conversation venue. Think how many HN commenters work for companies like Uber/Lyft, just for one example.
e: I misremembered; it was actually 1000 by 1980
We could decarbonize our grid today with only something in the vicinity of ~200 new plants. This is entirely doable. France showed how it’s done in the 80s. It’s sad we can’t start now.
I am not as familiar with the commercial side but I can say the military model is safe as all get out and produces less waste since you only need to refuel ever few decades or so.
Also NRC is very much still involved with Military applications, which at this point just involves moving expensive war ships around.
But do nuclear reactors really produce any waste, or only “spent” fuel that’s recyclable?
Granted the too high mark could still be perfectly fine to throw into a landfill and not impact anything, but nobody wants that in their neighborhood.
As to high level stuff which is what you are asking about, the spent stuff is really hot. To recycle, it would need to cool down first. Commercial plants place that in cooling pools, which is kind of bad if you have a Tsunami hit your plant (Japan), our something else.
So as to the waste element think I have 2% enriched object that is 100 cubic meters. The same in a highly enriched say 90% would only be about 2 cubic meters. This means my pools would be smaller, my overall size is smaller, and I can contain the smaller pool easier preventing the release.
On the politics side the idea of highly enriched is dangerous because it could be used for other purposes, however when those decisions were made I don't think anyone every imagined the concept of a dirty bomb in which enrichment is really going to matter one bit.
But besides that there is always waste. The key part is understanding what level of waste. There's a fair amount of low level waste (low radiation levels). In fact, this is like 90% of total waste (even more if you count my volume). But this type of waste is not the kind people are typically concerned with because it isn't radioactive for long nor is it producing dangerous levels. These types are not really recyclable though (concrete, steel beams, etc).
I do suggest reading up on our own AcidburnNSA's post about waste
Start with engineering courses, bringing on new talent.
Spin up hundreds of solar farms, battery factories etc
My question is are there real innovations to be made - do we need to rely on concrete and steel ? Are new homes possible in flat packs?
I would rather packet it into small parcels (10-100M) that explore the phase space of possible than think a quick government report can define infrastructure for a century
On top of which we should heed the strong town lesson - only build what we need, and cost in the car externalities in our cities.
Just thinking out loud ...
You will still need engineers for improving the technology, you will be on the bleeding edge. You will still need maintenance crews, the constructors are the ones that know the most about what they built, why not train them to maintain it as well?
First - 'Green New Deal' is a slogan, not anything material that helps fix underlying operational problems.
Second - we don't need to 'rebuild' most things, we need to fix, maintain.
Third - this is not an issue with 'green' or 'innovation' in the technical sense - it's about the efficiency of the bureaucracy.
Fourth - 'All the wasted money' is going into the pockets of seriously powerful vested interests - they are not interested in reform.
Are you ready for the political cost of taking on the Unions? Esp. public sector unions? They may not have their fingers in the pot, but they still likely a massive barrier.
What about exposing the fact that a ton of workers in infrastructure are in the country illegally? Who's going to 'clamp down' on that and pay the political price?
What about the fact that all these firms are massive political donors to the powers that be? How do we solve that one?
And fighting entities: SF is a tiny city. So is Palo Alto. So is Oakland. The 'Bay Area' needs coordination and nobody really wants to give up their little fiefdoms of power. So there are a lot of problems like that.
The issues are complex and a lot of it has to do with vested interests and power, not 'technology' or anything like that.
> What about exposing the fact that a ton of workers in infrastructure are in the country illegally? Who's going to 'clamp down' on that and pay the political price?
Unions are going to clamp down and pay the political price of squashing illegal labor. That's their whole purpose of existing! Anti-union sentiment in America reflects significant cognitive dissonance on this issue.
Public unions are a different matter. They're entrenched largely because private sector unions have disappeared. With greater private sector unionization public employees wouldn't dominate union lobbying as much as they do, and politicians wouldn't feel as obliged to protect them if there existed a larger pool of well paying, stable private sector jobs for the working class.
The entire discussion has been how this isn't the major driving factor of the cost of building. So why bring this up at all?
When it comes to nuclear, that's a problem the world over. Out of practice of designing as well. Look no further than the mess that is the EPR. On its face it seems like a boondoggle, but it makes a lot more sense when you look back at the history of nuclear construction: from 1971 to 1993, France was continuously building plants, first the 34 900MW CP-series (1971 to 1988) then the 20 1300MW P-series (1978 to 1993). The CP-series took 5-6 years to build and the P-series a bit more (6-7). From the mid-70s to the mid 80s, there were a dozen plans being built at any time, and they were being completed.
Then came the N4, that thing had serious teething issues, the first model started construction in 1985 but took 12 years to complete. By the time the 4th was completed, it was down to 7 years. But the 4th was the last N4 to be built. It's unclear to me whether the N4 slowdown was intended all along or whether the teething issues made them take a look at construction and pump the brakes, but in the space of 5 years the country went from building 12 plants at a time to building 5, then 4, then 3, then 2, then 1.
N4 at least overlapped some with the tail end of the CP-series and the middle of the P-series, but the first EPR construction was started in 2007, 5 years after the last N4 (Civaux 2) was completed. I can't even imagine the loss in institutional knowledge over that span.
I think there's a perception problem.
Do people readily go to school to study nuclear engineering?
I don't think it carries a stigma per se, but it would not be that sexy, and it would be harder to get a job and keep it subject to political whim on a 4-year-cycle.
(A more practical/guaranteed job would probably be a petroleum engineer, especially wrt fracking)
Yes, people do study nuclear engineering. I was considering that path myself in university, but ended up going more towards science and doing several years of research in nuclear physics labs instead.
I'm very glad I didn't end up doing nuclear engineering. The nuclear industry stagnated and failed to address cost problems and bad project delivery (cost overruns, delays, etc).
And then between 2010 and 2020 renewable energy scaled up and became incredibly cheap, in fact the cheapest source of energy in most countries: https://about.bnef.com/blog/scale-up-of-solar-and-wind-puts-...
Between 2010 to 2019 wind energy become 70% cheaper and solar became 89% cheaper: https://www.lazard.com/media/451082/lcoe-8.png
Battery costs have dropped 75% over the last 6 years: https://www.greentechmedia.com/articles/read/report-levelize...
> I think there's a perception problem.
Somewhat, but the nuclear industry did a massive PR campaign to address that.
Blaming perception or "green activists" or "fear of scawy radiashun!" is an easy straw-man for them, but the real obstacles are more practical and harder to address: the economics of nuclear are not good. This is compounded by a problematic history of delivery problems.
> Yes, people do study nuclear engineering.
Note I said "readily" not "really". I see you made the calcluation when you made your decision.
It's a shame really because I believe nuclear power has great promise in benefitting society.
Too bad the moonshot level investment in nuclear went towards military ends (france in 80's excepted). And too bad funding is dependent on political whim.
Although solar and wind is working, I worry that might be a "save ourselves rich" strategy.
When you look at this table:
material energy density mj/kg
Diesel fuel 38.6
Lithium-ion battery 2.63
Loan guarantees are a particularly common example -- for example, last year the US govt provided $3.7 BILLION in loan guarantees for the troubled Vogtle reactor builds in Georgia. The way loan guarantees work is that the government agrees to pay the debt owed if the company goes bankrupt or cannot complete the project; this is surprisingly common actually, since the same project had already driven Westignhouse to file bankruptcy.
Solar and wind aren't likely to make a handful of people extremely rich -- the profit margins on the components are pretty low due to the high degree of competition pushing them down. Building solar and wind farms to sell their power does produce a solid and reliable financial return on investment, but it's still less than 10% (even though the energy return on investment is good).
> When you look at this table [energy density]
For power generation, energy density is largely irrelevant.
Also these energy densities are apples-to-oranges comparisons. You can't burn uranium without a fairly large, heavy reactor. There are no "nuclear cars." Similarly diesel requires an engine although it's smaller. Batteries aren't a power source on their own, they're storage, and you're not "burning" them up.
i)getting people trained,
ii)having a kind-of minimum wage accessible to many people.
And there's plenty of training courses at the local caterer center and community college for both those jobs at reasonable rates. Local manufacturers often pay hourly+tuition for their best fabricators or line workers who want a promotion to the welder position to go through one of those programs.
There's lots of welding schools churning out 'graduates' throughout the year. Welders are almost always the first guys laid off in shops.
The 'learn to code' thing thrown around would be better.
The whole narrative of producing more 'software developers' in general though? No thank you. I see enough people coming off of less than stellar bootcamps (there are, in fact, good ones, though I'm finding this less true over time) who just see dollar signs who have no interest in this as a craft. I don't want to encourage that, at all.
In fact, I want certification for the title of Software Engineer, no different than having to be certified like civil engineers do. Uncle Bob is right about this one.
A talk that really opened my eyes was Mary Poppendieck's "Tyranny of the Plan": https://chrisgagne.com/1255/mary-poppendiecks-the-tyranny-of...
It turns out the Empire State Building was created on time and under budget, and against a very hard deadline. They did not have a complete plan when they started; they were designing the top floors as they were building the bottom ones.
In software, we've become familiar with how over-planning creates a lot of waste. But I was still surprised how broadly that lesson applies.
They sign big leases with big tenants before they can get financing, and the building needs to be open when the lease says it will.
Strangely enough, pretty much the last thing they do is to design the foundation. Once they know the building is a go, they drill and take core samples at dozens of places around the site and use that information to design a foundation that will hold the building as designed. This is the when things start to cost large amounts of real money, so they don’t do it until they have to.
The concrete mat that ties all the caissons together is a single pour that can involve hundreds of concrete trucks and take a day or more to do, all of it orchestrated to ensure every truck arrives exactly on schedule.
All this is to say that there is still an awful lot of skill in the construction industry.
And I'll note that the Empire State Building was not a standard office building of the day, but the tallest building in the world. (A title it held for 40 years.) People building today have an 80-year advantage, plus the rise of computers. You'd think we'd be able to do at least as well with every building, but we don't. That's in stark contrast to building safety, for example, where we're very good about learning lessons about keeping buildings from collapsing.
Luckily for the nuclear industry, the engineering capability still exists in the US to design a whole plant, and a lot of the manufacturing base still exists. Big US nuclear players have had a base load of domestic upgrades and international new plant jobs that have kept these capabilities alive.
But for construction, we really are awfully thin on specialized trades. Welders, especially, are _always_ in short supply.
Welders, especially, are _always_ in short supply.
A few months at the local community college can get you to the point where you can do the most basic welding jobs, but these low skill jobs are the ones that either left the US or got automated, and the few such jobs that remain are mostly done by mediocre welders who should have retired years ago. If you want to do the high skilled welding that pays well, you need to essentially support yourself for years as you develop those skills on your own - and most people who have the means to do so have better opportunities in other fields.
Realistically, employers need to eat the cost of training new people if they want the pipeline to open back up again, but it's more economical to poach a good welder after some other sucker puts their resources into them, so you get a classic tragedy of the commons.
People look at the small difference between pay at the factory or mine (dangerous) and pay at Walmart (not quite as dangerous + employee discounts) and make the rational choice.
During the 2010-2019 US recovery wage stickiness was noticed, even with everyone complaining about not being able to find qualified workers. Companies were very reticent about increasing wages, often preferring to go with signing bonuses.
It is suggested that this reticence/stickiness was because after 2008-2009 GFC many places were stuck with high wages (from the previous boom), and getting people to cut their salaries was almost impossible.
Source: used to weld at the NASSCO shipyard in San Diego.
When welding, you put an incredible amount of heat into the material. This causes it to move in real time. A welder needs to predict how it will move ant actively account for this so that the final piece winds up in the right condition. The tolerances depend on the application - for furniture who cares if it's out a bit, for a coolant line to a reactor you need it to be damn near perfect.
Then there's heat penetration - adding heat to the material changes its material properties. Go too slow and steel becomes excessively weak, go too fast and you don't form a strong bond. Again, big differences between "probably won't break if you sit on it" and "this will kill a dozen people if it fails"
Finally, there's just plain old margin for error. If you're welding together consumer products, it doesn't matter if you scrap one every now and then. However if you're trying to join together two multi-million dollar custom fabrications, you need someone who's going to walk up to this and get it on the first try every time.
I'd compare it less to being a major league baseball player and more to being a professional musician - you can't determine that someone could never do it, but some people are certainly born with a knack for it and you can't simply churn out more on a whim.
In short supply for the wages offered. Bid enough out there, and the positions will fill. Bid consistently such that precarity is avoided and bid even more beyond that, and the bench will deepen. Short supply is entirely addressable by buyers.
There are definitely some industries where the cost to get to the level where you make good money is too high, especially when you aren't sure when you start if you have the required talent to make a great living.
There will always be a shortage of great NBA centres - for reasons outside labour market functioning.
There is only ever a shortage of sufficient compensation to clear the market for a desired level of skills availability.
There are vested interests waging a war against the US building infrastructure because its ideologically against the narrative developed.
"Starve the beast" has turned any kind of fiscal spending into a huge political battle. It used to be, funding basic things was just a given. Now it's a fight over every little dollar.
In approximately 61 days, conservatives in the US will be in an absolute panic about the financial state of the country.
The US has full ability to pay such debts, at the cost of inflation.
Large deficits would be fine if the spending were for investments with a high ROI, such as infrastructure or nuclear power.
Indeed, going further into debt for an investment with great ROI makes sense. Regardless of the debt level, a good investment is a good investment. And a bad investment is a bad investment.
Alas, most spending of the US federal government isn't an investment of any type.
That point could reasonably be interpreted as rather than taking in a dollar and paying back 50 cents, the US has the power to take in an hour of labour and pay back a half hour. And claim that it fulfilled the terms of the agreement.
That isn't an improvement. It is nothing more than muddying the waters enough it makes it hard to point out that the situation is no different from a default. Which I suppose is why they do it.
There is an amount of stuff in the world at this moment. The US either gives back more stuff than it borrowed, or less. The idea that it can give back less stuff but that is OK because it is a government is a foolish idea. Making it hard to understand who is getting what doesn't magically mean everyone is happy, it just means we only find out who is paying with benefit of hindsight.
Anyone can pay back less real value if they have terms where the rate of interest is lower than the real rate of inflation.
Creditors of a government can mitigate the risk of that happening due to the policies of the debtor government by setting repayment terms other than in fiat currency of the debtor.
They often choose not to; heck, in the case of the US, it's happened that they choose to lend despite negative nominal rates, even before inflation.
Unless you consider being the sovereign issuer of the world's reserve currency, and the military, civil government, legal system, and property rights behind that to be an investment of some type.
Education could be an investment but per student spending has tripled over 50 years, yet it would be hard to argue that there is a high marginal return on investment from the extra spending.
Same with healthcare. Plenty have noted that the US spends more per capita but has worse outcomes. Seems like there's simultaneously cheaper and more effective approaches out there.
Social security is just a transfer payment, but not sustainably structured.
You mean those who actually pay taxes? The top 10% pays 70% of all federal tax.
The most current tax cuts also lowered the brackets in almost all cases, as well as raising the standard deduction. These changes reduced taxes for almost every American.
> In approximately 61 days, conservatives in the US will be in an absolute panic about the financial state of the country.
As opposed to the last 4 years where democrats in the US were in an absolute panic about everything.
> Deutsche Bank’s Torsten Sløk says that the distribution of household wealth in America has become even more disproportionate over the past decade, with the richest 10% of U.S. households representing 70% of all U.S. wealth in 2018, compared with 60% in 1989, according to a recent study by researchers at the Federal Reserve. 
Unless a bank is in trouble or someone wants to fight a war.
unless that spending is on them. That subsection of the population LOVES welfare when they get it and it's called something else. You could just call this something other than welfare.
Excess on all sides
Strangely though "Defund the police" goes the other way, politically. /ducks
Oh of course! It's the Republicans' fault, how predictable. If only we had a Democrat utopia like California at a national level, we'd have nuclear plants everywhere and everything would be perfect.
So where do they go now? Are American trained Mech/Civil/Industrial/etc Engineers really going overseas in large numbers? We all know the cost of schooling is now exorbitant in the US and engineering salaries (certainly for software but I'd guess other disciplines as well) are generally higher here than anywhere else in the world. Where could they even go to make enough to pay off their student loans?
No, we definitely have those people.
Thinks are more complicated across the board, safety practices are higher, contrary to public opinion wages are higher in this sector and I think there's a soft kind of pervasive corruption going on at the government and contractor layer, where there's just padding, waste, overbidding, back-scratching etc..
Montreal had some serious problems with corruption and was able to make progress on it, states and municipalities need to do the same.
I would vote for the first person that wanted to make these things more efficient and transparent.
The US has a complex state and a number of private corporations with a relationship to the state and each other. Who are you talking about in particular?
Edit: I should add. It's not just the problem of having trouble building things but companies that get a lot of money out of failure and those companies symbiotic attachment to the government - consider the X billion dollar California rail planing process. Whoever did that didn't even have to create more than minimally to still leave with truckloads of cash. And they'll be on call for next time. Even that is just an example.
Unless building a nuke plant is a common thing where the crew that built a plant in Georgia can then go build one just like it in Alabama then one in Tennessee, then in Ohio, etc, then I don't see how building two plants with identical layouts can leverage economies of scale. For example: Wolf Creek NGS in Kansas and Calloway NGS in Missouri were apparently the first two plants in the US to be built using the same blueprints. If two more plants were built today with those same blueprints but by different construction crews who don't have any of the tribal knowledge from the construction of Wolf Creek and Calloway then what you have are four essentially bespoke plants that just happen to use the same blueprints.
To respond to your exact point, big parts of the nuclear-qualified workforce in most places really do move from large job to large job (assuming relatively static demand), so you do get that transfer of knowledge on sequential jobs.
Also, don’t forget the design and manufacturing that happens off-site, which can be significant and often is a huge driver of risk and cost. (10 MW vertical motors! Big safety-related pumps! Mega-sized forged components! Specialized custom fabrications!) The back office engineers and subcontractors and factory floor people who make them remain pretty static as long as there is work to be done. By the Nth unit, there is know-how and known problems are worked out; some of this is translatable into drawing updates and schedule resequencing but really a lot of it is expertise that stays in peoples’ heads. Once everybody is demobed and scatters, that is all lost.
The link says the savings from Newport would be $1.6B.
It also quotes the Navy acquisitions chief pointing out "about a third of the cost of a carrier comes from government-furnished equipment that the Navy would contract for separately" and that he previously said the overall savings of ordering two at once would be around $2.5B after considering similar efficiencies of "scale" from those vendors.
Considering the cost of these Ford-class carriers is around $13B this represents a savings of about 10% overall, at least according to my crude, back-of-the-napkin math [ 2.5B/(2x13B) or 1.6B/(2/3x2x13B) ].
So it might be closer to "buy 10, get one free".
To be fair, the building of the actual carrier is just part of the price of a carrier. What's the cost to also fit that carrier out with all of the various aircraft required to make the carrier worth having? Didn't we see an example of this when the NSA donated Hubble equivalent satellites to NASA, but NASA had to politely say no since they had no budget to operate them?
It was the NRO not the NSA and NASA did accept the donation. They announced the mission schedule for one of the satellites in 2016 
Right idea! The answer is "hardly anything, relative to crewing it for its useful lifetime", but you're barking up the correct tree.
Not to mention the hundreds of small decisions related to "X part supplier went out of business. Y part is similar with a slightly different alloy and mechanical properties, is it a suitable replacement? how can we verify this?"
The original design teams would have auxiliary artifacts that were vetted, and tribal knowledge to help quickly answer these questions. Subsequent design teams will not. The timescales between plant construction exceeds most engineer's memory at 5-10 years.
We have newer reactor designs, materials, and engineering knowledge today that could significantly reduce cost just in material savings or construction time.using something like FAST reactor, is significantly different that the older tech and could save 90% on fuel and waste.
Unfortunately most of the new reactors built in the US and Europe have run massively over time and over budget, despite new technology. Vogtle 3&4 in Georgia drove Westinghouse bankrupt. These were modern AP-1000 models. Flamanville 3 in France (an EPR) is running nearly triple its cost estimate and the delivery time ballooned to 15 years. Olkiluoto in Finland (the first EPR) went massively over time and budget as well. These reactors were specifically designed to be more cost-effective and promised much lower prices, but failed to deliver.
The problem in the nuclear industry isn't the technology itself, but the fact that they consistently fail to deliver projects within their allotted time and budget. Unfortunately this shows no signs of changing, and renewable energy industry looks poised to completely out-compete them in the energy market.
I say this all as someone that used to have high hopes for nuclear tech, after working in nuclear physics research all throughout university.
Thus, breeders generally end up being more expensive than a conventional BWR or PWR.
Here I should mention that I spent some time in nuclear physics research. There's a lot of misinformation floating around about nuclear energy. Most of the "miracle solutions" don't live up to their promises (especially thorium tech and breeders). If they did, we'd already be using them -- nuclear engineers are not fools, and most of these reactor concepts have been kicked around for literally decades.
One other point: the physics behind breeders and conventional slow-neutron reactors isn't fundamentally different. Both neutron capture ("breeding") and fission ("burning") reactions happen in both, the ratios in a breeder are just optimized to favor the first process more. In fact in conventional light water reactors, around a third of the energy released comes from fissile isotope bred from fertile isotopes such as U-238.
I'm not saying that the engineers are idiots. But there are some engineers (supported by government or corporate funds) still building new prototypes and testing new designs, such as FAST. Especially in the US, a driving reason that new designs aren't used is that there have been few built I'm recent decades - partially due to lower cost alternatives and also due to public opinion.
> eliminating the need for ever increasing safety tech and complexity of it for conventional reactors would be a cost savings
Passive safety features are useful, but they don't end up replacing active features (you still need to control the reactor during normal use). At best they might allow for reducing the redundancy level on a critical system -- which might save a bit bit of money, although not much.
Better safety is always a great feature in general, but it's not close to making breeders cost competitive on its own.
> Not to mention the clean up costs when you compare to a conventional reactor that could melt down, even if it's rare.
Actual meltdowns are exceedingly rare (and catastrophically expensive + devastating), so you don't really factor them into the cost equation for a normal reactor.
> Especially in the US, a driving reason that new designs aren't used is that there have been few built I'm recent decades - partially due to lower cost alternatives and also due to public opinion
Mostly cost tbh -- nuclear energy has been historically somewhat unpopular (especially after major accidents) but there's a lot of industrial projects that continue anyway despite being unpopular (oil pipelines etc). The financials for nuclear reactors are not great (it's a big, financially high-risk investment that takes decades to really pay off), so there's less incentive.
> announced that completion of the project would be delayed by 3 years to 2030. It also estimates the cost would climb from $4.2 billion to $6.1 billion.
Unfortunately it has become a pattern now for the nuclear industry to promise that the next tech will suddenly make nuclear energy cheap and fast to build. They consistently have failed to deliver on their promises -- the fiasco of the AP1000 reactor build at Vogtle in Georgia is a recent example.
It seems like the problem of the nuclear industry is the industry, not the technology itself. They're too used to relying on fat taxpayer subsidies, and are not well equipped to compete against other energy sources on the free market.
* Often the starting point is a poorly organized mess that needs to be unpicked and understood.
* People conduct "reviews" of existing work that consumes budget and leads to new issues being found.
* You are continuing an existing chain of communication, but with a loss of continuity. The people you need to ask can't remember, or are not available to ask.
* Overly optimistic budgets lead to corner cutting and mistakes.
I assume we'd lose power during the transformer steps, but would it preclude building the plants away from people and groundwater reservoirs?
It's not as attractive for managing nuclear accident risk as you might think, as nuclear is already struggling with cost competitivenss even without HVDC lines, and risk reduction per buck of other safety design features are better.
But it's brilliant for eg hydro (for obvious reasons), wind power (because 2000 km away it'll be windy when you have local lulls and vice versa) and solar (2 time zones worth of distance balance out production/consumption peaks nicely).
> France aims to rapidly develop renewable wind, solar and biomass capacity to curb its dependence on atomic power, reducing its share in its power mix to 50 percent by 2035, from 75 percent today.
We have to look at France and how much carbon it produces. Right now it is one of the lowest producers in Europe. Let's look at the electricity map. Sweden, Norway, and France are leagues ahead of others in terms of carbon emissions. France's plan is first to replace existing natural gas, biomass, and coal with renewable resources. The second part of the equation is that their reactors are reaching EOL, so do you build more or replace them? If you pay attention to energy trends solar and wind (something France has an abundance of) is getting much cheaper and battery storage is getting cheaper (France doesn't have to bet as much on battery storage since they can over produce and sell excess energy, which they currently do a fair amount of). So if you're going to take bets this is still a good bet. A big part of a good and stable power grid is by having a diversification of energy resources. 75% of your energy being dependent upon one resource is not a good idea. No matter the resource. Even 50% is high, but acceptable. They aren't planning from going away from reactors, there's even one under development. But you also want to hedge your bets. If any of these factors (solar, wind, battery storage, smart grids, ITER, etc) don't pay off, then they need to maintain their nuclear grid. It would take a large revolution in energy development for France to be able to still produce so little carbon and provide its citizens with a modernized (electrified) country.
Also consider that France doesn't have good access to hydro like Norway and Sweden do so its options for clean energy are nuclear, solar, and wind (lots!). They should, and are planning on, using a diversification of these. Nuclear provides a strong baseload and the others supplement. You may notice that this is a key argument made by many proponents of nuclear. Anyone that says the grid should be entirely nuclear is an armchair scientist who understands very little about nuclear or the climate. But the same is true for those that think we can solve the issue with just solar and wind.
So if you're saying France is turning away from nuclear, then this is adding desires into a plan that does not express or concern itself with those desires. A big part of this decision is about diversification and increasing energy independence (just like recycling fuel is a big part of their energy independence, which they power a whopping 17% of their grid with recycled nuclear alone).
The UK is doing fine with a renewables-heavy powergrid, as are Spain and Portugal. 40% of their electricity comes from this, and the share is rising steadily.
> However, the bill also calls for "realistic goals to transform our energy model by increasing the timeframe for reducing nuclear power to 50% by 2035 instead of 2025, which would have required the construction of new gas-fired plants, and would have involved an increase in our greenhouse gas emissions."
I'm sure World Nuclear News is more favorable to nuclear power, but I don't see how that is relevant. Do you believe that this article fabricated the contents of the French bill?
This comes off more as a cheap jab than a substantive claim of bias.
Legislation gets written and rewritten as timelines get tweaked. That's a reality. The core goal is unchanged.
They literally are, and have formally said so. They're not shutting down all their reactors right away or anything. But for a country that took pride in betting big on nuclear, officially planning to go from 70% nuclear to 50% is a pretty huge drop. They've already shut down the first two reactors at Fessenheim as part of this.
Yes, they're kicking the can down the road slightly at last news. That's not surprising since many of the reactors may be possible to life-extend to 50 years, and renewable energy costs are dropping quickly. Delaying a few years saves some money. But that does not change the fact that many of the reactors will not be replaced when they hit end-of-life.
> They literally are, and have formally said so
As I stated in another reply to you, reducing dependence on nuclear has a lot of advantages unrelated to "nuclear is bad" or "nuclear is not clean" or etc. Like I said before, no matter what your energy source is, 75% of your power being produced from a singular source is not a good idea. You may be familiar with the old saying "don't put all your eggs in one basket." This is the same reason we don't invest in a single stock. Dropping to 50% is far from getting rid of nuclear and it is an absurd claim.
> But that does not change the fact that many of the reactors will not be replaced when they hit end-of-life.
Many, but many are planed to be replaced. You're focusing too much on the reduction aspect. Reduction is not elimination. France has no plans on eliminating nuclear in the foreseeable future. The only way this would happen is if ITER was a major success and small versions could reliably be developed and deployed. I'm not counting on that.
I already provided a citation for this - https://www.reuters.com/article/france-electricity-solarpowe...)
>> France aims to rapidly develop renewable wind, solar and biomass capacity to curb its dependence on atomic power, reducing its share in its power mix to 50 percent by 2035, from 75 percent today.
A quick google will turn up dozens of other sources discussing that if you like.
> reducing dependence on nuclear has a lot of advantages unrelated to "nuclear is bad" or "nuclear is not clean" or etc
When did I even say that? Please have the decency NOT to convert my educated and reasoned points into a straw-man argument. I spent years working in nuclear physics. I'm not making some idiotic "nuclear reactors will turn us into glowing mutants" argument here.
The real issues with nuclear are -- and always have been -- simple, practical problems of cost, time to construct, and the usual problems of cost overruns and delays that you see with constructing a very complicated system. The Flamanville EPR has been a fiasco, with costs triple its original estimate and a timeline that ballooned to 15 years.
In comparison, the competition from renewable energy has heated up rapidly. Economies of scale are rapidly driving down the costs renewables and batteries (and the underlying technology is improving rapidly). Between 2010 to 2019 wind energy become 70% cheaper and solar became 89% cheaper: https://www.lazard.com/media/451082/lcoe-8.png
Nuclear energy in 2020 is often quite expensive compared to renewable energy, and the comparison is only getting worse over time.
> France has no plans on eliminating nuclear in the foreseeable future.
In 2020, Energy Minister Élisabeth Borne announced the government would not decide on the construction of any new reactors until Flamanville 3 starts operation after 2022. Citation: https://www.neimagazine.com/news/newsfrance-to-decide-on-new...
"France has undertaken to cut the nuclear share in its electricity mix from around 75% to 50% by 2035 while increasing the share of renewable solar, wind and biomass."
“Whether we are looking at 100% renewables or a percentage of new nuclear, we want to consider all the elements, including technical, economic,” she noted. “On such important subjects, we must make rational, reasoned decisions, and that is the objective of the various studies that have been launched.”
To put that all together: France is cutting their use of nuclear, and waiting to decide whether or not to replace reactors that are fast approaching end-of-life. They're going to look and see how the energy market shakes out.

Wow this conversation is a mess.
From reading the link I get, change orders cost money (duh!) and that there are a lot of change orders, particularly to older designs due to "changing regulation". Cause presumably before starting construction the older design has been mitigated to deal with newer regulations.
Which from my own biases, seems to mean that courts/etc are stepping in and modifying the regulations during construction and that costs a sh*tload. Otherwise the builders are negligent, or simply that it took 30 years to get approval for the plans, but now its a catch 22 because they are outdated.
Consider, for example, that one year into construction of a new power plant a completely unrelated investigation into fires concludes with the finding that a certain kind of electrical wire, when installed incorrectly, can short and cause a fire. The power plant has already installed miles of the exact same wire. The wire manufacturer has a new product that prevents incorrect installation, but the plant designs call for the old wire. What to do?
* Pause construction while they adjust the plant designs with the new wiring?
* Continue construction, but inspect the existing wiring, and reinstall if necessary?
* Leave the wiring in place, but install a fire-remediation solution for the already-installed wiring?
All large systems have to deal with these kinds of changes. (It’s interesting to look at the changes in a “class” of ships over them as they build each one, for example.)
There's no equivalent of the NRC setting welding standards for the steam systems of coal plants and demanding that control systems are guarded against wiring fires. General safety and environmental regulators are often deliberately underfunded by business-friendly legislatures, and even violations that they catch are rarely considered severe enough to shut down a site until remediation. And of course nuclear reactors are (rightfully!) expected to contain their waste products, while combustion plants still get a free pass to dump CO2 into the atmosphere.
The result is that very few industrial sectors in the US have experience receiving meticulous government oversight that they cannot ignore. Aerospace , pharmaceutical manufacturing, and nuclear power are about the only ones I can think of. If contractors don't have institutional knowledge of actually working on nuclear projects (which are already more complex than a big coal or gas project), they may not be prepared for regulators that actually check the work and demand it adhere to documented standards. Just about every other project can let marginal welds or inconsistent paperwork slide with "eh, you tried." The really expensive part about nuclear projects isn't doing the work. It's redoing the work that you failed to do up to standards the first time.
But you absolutely do not want to make the NRC more lax to bring it in line with the barely-there standards the rest of industry is used to ignoring. You don't want the nuclear equivalent of the West Fertilizer Company -- inspected twice in 28 years, minor violations ignored until the plant exploded .
 You might even put an asterisk on "aerospace" considering the 737 MAX debacle.
> Among the surprising findings was that contrary to expectations building subsequent plants based on an existing design actually costs more, not less, than building the initial plant.
Given your example wouldn't that mean replacing the wiring of all previous plants of the same design? I suppose this is one way cost overruns get compounded - an issue discovered during the current build would likely apply to the previous builds. (any actual examples of this?)
> if more components of the plant, or even the entire plant, could be built offsite under controlled factory conditions, such extra costs could be substantially cut.
Wait what? France builds with relative similarity and it's cheaper. The problem is with US regulation, politics and CYA hand-wringing, imo.
The project was planned to involve around €3.3 billion of capital expenditure from EDF, but latest cost estimates (from 2019) are at €12.4 billion. Pierre Moscovici, president of the Court of Audit, gave a statement on 9 July 2020 concerning the release of the report on the delay costs of the Flamanville 3. The report of the Court of Audit reveals that the cost of Flamanville 3 could reach €19.1 billion when taking in account the additional charges due to the delay in construction.
> CGN Power, the listed unit of state-owned China General Nuclear Power, China’s largest nuclear power projects developer, has announced a 17 per cent capital increase at its Taishan nuclear project, raising concern cost overruns and commissioning delays will continue.
> The company will inject 2.94 billion yuan into its 51 per cent-held unit Taishan Nuclear Power Joint Venture, which will see the unit’s total registered capital to 28.6 billion yuan from 24.4 billion yuan, the company said in a filing to Hong Kong’s bourse late on Tuesday. Provincial government-controlled Guangdong Yudean, the province’s largest power producer, owns 19 per cent stake, and CGN’s French technology partner EDF holds 30 per cent stake.
> CGN said the capital injection serves “to enhance its financing ability so as to meet its fund requirements for engineering construction.”
> The project, which CGN said on track to become the world’s first third-generation nuclear reactor built on the European pressurised reactors (EPR) design to achieve commercial operation, was originally expected to have its first generating unit come online in December 2013 followed by the second in October 2014.
> The timetable of the two units subsequently slipped to the first and second half of this year, and further to the first and second half of next year after “comprehensive evaluation on subsequent engineering construction plan and relevant risks,” said CGN a year ago.
I also get a bit nervous about how fast they've scaled their nuclear sector and pumped out plants. It reminds me a bit of the big historical push the USSR did into nuclear tech -- which culminated in the Chernobyl incident because they overlooked issues they should not have in order to keep things moving fast.
A lot of technology and engineering lessons have been learned since those days... and so far I haven't heard anything specifically concerning about China's nuclear reactor fleet. But there's always going to be a little doubt in the back of my mind.
The article specifically addresses your cynicism about "regulation and politics", only they call it "safety regulations".
They found it not to be the deciding factor. Lack of construction outside the US would seem to support that conclusion or, alternatively, to accept those factors as unchanging, sort-of like the laws of nature, and to blaming democracy for all ills of society.
Taishan units are up and running

but we're talking about 20% overrun, which I could call a good upfront guess
Incentives make a big difference here. Ignoring everything else, airlines don't want to lose their hundred million dollar machine in an accident. And the person most directly responsible for the safety of the flight -- the pilot -- is sitting right there in the machine with the rest of us. It's a good arrangement with a long track record.
I could imagine corporate-run nuclear plants that have the same incentives as airlines. I could also imagine bad ones, run by Homer Simpson. It probably makes more sense to judge case by case.
Airlines are also different from power utilities, in that it's very easy to change airlines and not very easy to change grid operators. After Fukushima it's not like consumers could switch to a power utility other than TEPCO.
So how exactly do you enforce that corporate executives and their families must live on site for decades?
> In a notice dated Nov. 6, regulators noted a “substantial safety culture issue” at Watts Bar at the time of the incident. They also found that “TVA senior management and staff failed to communicate with candor, clarity, and integrity during several interactions with the NRC during the course of the inspection and investigation.”
> The incident wasn't recorded in the plant's logbook and managers later misled NRC investigators about what had happened. The shift manager told investigators he wasn't truthful with them at first because he feared that whatever he said would be relayed back to management.
> last year, TVA was ordered to rehire and pay thousands of dollars in back pay and compensation to a whistleblower who raised concerns about nuclear safety.
And then there was the nuclear corruption scandal in South Korea:
And let's not forget when a nuclear company literally bribed Ohio politicians with $60M to get a $1Bn+ bailout:
Renewables are exciting. Jumping too fast into it like Germany did (and is now polluting as much as 8X France with 450g CO2 / kWh) is much less exciting.
I wish there was a bit more expert involvement in the way we choose our energy policies (and much less tribalism and populism).
* 1x capacity, 0 storage: 74% of electricity demand
* 1.5x capacity, 0 storage: 86% of electricity demand
* 1x capacity, 12h storage: 90% of electricity demand
* 1.5x capacity, 12h storage: 99.6% of electricity demand
Nobody who follows the energy sector closely thinks ElectricityMap has any credibility for country-to-country comparisons. The datasets are extremely fragmentary and have huge yawning gaps with no data available, which should be the first red flag for anybody citing it. It might be useful for trends within a given country, but not the way you're citing it.
Also: accounts popping up out of the woodwork to argue passionately for an out-of-favor technology reeks of a dying industry trying to revive itself with public relations. 3/4 of those accounts seem to cite ElectricityMap, oddly enough...
Ensuring that there is demand allows investment to be made in production, which allows competition and learning, and acceleration of the decrease in cost.
Batteries are halving in cost every handful of years because there is a guaranteed market that allows construction of more production facilities.
Batteries are currently being deployed very cost-effective for replacement of gas peaker plants and for frequency regulation. They are also being deployed on the grid as "non-wires-alternatives" to transmission upgrades. As we transition to a carbon-free grid, they will find even more use.
A huge fraction of planned solar farms in the US have storage built in, because of the efficiency of reusing the same DC to AC inverters, and because for quite a while now, panels have been cheap enough that some panel generation capacity is thrown away in order to get more output at other times of the day.
It is a mistake to think of batteries as needing some sort of technological leap to serve our needs. If we had to, we could deploy them at current prices and build a renewable, carbon-free grid more cheaply than we could with nuclear. But we are only installing them as necessary as we replace aging infrastructure, rather than shutting down existing infrastructure that hasn't worn down.
As the cost of storage+solar drops below the fuel+operations expense of natural gas, we will start shutting down natural gas plants before their natural end of life, resulting in wasted costs. I have a feeling that any naturals gas turbine installed today will be considered a boondoggle within 5-10 years.
The future is now, when it comes to storage, we just haven't had time for reporting to catch up.
 Yes, that is multiple plants to create the equivalent amount of capacity.
 Ultra Safe Nuclear -- https://news.ycombinator.com/item?id=24505727
This is in contrast to smaller projects, especially during recessions, where construction firms may be more likely to need the work (lower bids) and also don't have the expectation that the project will have to be completed (they can wait it out to extract more money from a contract).
I'm sure it's hard to shift these norms. As the buyer, it's hard to credibly threaten a hard limit. Everyone knows that, in 10 years time with an 80% done plant, and a construction company in bankruptcy proceedings, of course more money will be found.
Look at Flamanville in France: budget triple the "estimate", 15 years to construct. France has more nuclear energy per-capita than any other country on Earth, so it's not like they don't know how to "do" nuclear.
Those who decline to play by the rules we have ended up with, don't get the contract & go out of business, or don't get elected. It seems like an incentive problem. And a possibly unsolvable one, for huge mega-projects like this -- constructed over decades, dangerous & high-tech, and completely useless until 100% completed.
Wind energy seems much more healthy in this regard. You buy off-the-shelf units, from a factory. If you don't like the first 10 they install, you don't buy the other 90, and still get 10% the power. It's much closer to buying cars, or pencils, which our society is pretty good at optimizing. Every year we improve the process, and these steps add up.
You are correct that wind has a lot more flexibility in this area than nuclear. It is also much easier to scale a project up by just adding more turbines. In the case of older, smaller turbines they can be replaced with more modern turbines that yield more power (called re-powering).
In general wind power and solar have much better economies of scale too -- the more you build, the cheaper it gets. Nuclear doesn't tend to follow that pattern -- although there are attempts to create it via small modular reactors (SMRS). The jury is out if that will succeed or not (early signs are not great though).
From the 90s to the mid-2000s there was probably a window for development in this area. But the nuclear sector stagnated as a whole, and then fracking made natural gas cheap enough that people wouldn't consider it.
The jury is out on SMRs still. They're promising a lot, and the tech and engineering has improved. But plunging costs of renewables mean the window of opportunity for nuclear tech is probably mostly closed in the West. This article from a highly respected energy sector analysis group is worth a read: https://about.bnef.com/blog/scale-up-of-solar-and-wind-puts-...
India and China are the big markets for nuclear right now -- their energy demands continue to grow, and they're building reactors as part of an all-of-the-above model. France MIGHT be a potential buyer of SMRs (their reactor fleet is getting close to end-of-life), but their nuclear companies have put a lot of push behind the EPR design.

The two quoted authors in the press release are a prof in energy studies and a nuclear engineer.
What I notice is that MIT does not have a Systems Engineering undergraduate department, but numerous specialties.
In a large design/build project such as a nuclear power plant, the systems engineering group (there must be exactly one) keeps track of the performance and function of each of the subsystems (civil works like containment, basements, buildings; electrical; controls; HVAC; the nuclear bits; and so on). In addition, it is the system engineering group that responds (or directs responses) to a change order request, and the overall impact on expense, on functionality/reliability/safety, and schedule.
It seems these are responsibilities that are not identified here with a known role; instead the authors reinvent system engineering for themselves.
There is a lot of SE work done in numerous industries (Elon Musk is what I would call a systems engineer, based on how he identifies things to do and how he gets them done. His degree is not in SE though).
A short list of US universities offer SE or related disciplines; in California/New York/Illinois. MIT is not one: it has a research group not a degree-granting program.

It’s easy to say that your design is airtight, but the reality is far different, with the laws of entropy taking over after decades of operation. This is when your parts starts to fail. Seals starts to leak. Things just wear out and fall apart.
This is why the thing is so complex.
Then, you have to deal with the radioactive waste byproduct which lasts for 10,000+ years. How do you even deal with this, when no government in human history has lasted longer than a few hundred years.
As much as nuclear is a necessary evil to maintain baseload, since solar and wind doesn’t always function, I think we need a new energy paradigm.
I’m thinking we need to go with solar space power generation, and beam the energy down via microwave or laser. Maybe laser is a good candidate. Beam the laser down, and collect it with photovoltaics. And the laser can run 24/7, even at night.
Asking a friend: Maybe someone can run the efficiency numbers on this. But even if it’s less efficient than nuclear, this is probably far safer than nuclear ever will be.
Putting a giant laser in space doesn't seems _that_ safe.
The proposed space based energy things are very low efficiency. After all, you can collect enough solar power on Earth already, the problem is efficient distribution. (And if you put a big laser/maser in space that still would not be able to provide baseload if it's not always in line of sight.)
And launch costs are prohibitively expensive right now. First we'd need to bootstrap a cislunar economy (eg mine and manufacture stuff in space, so we don't need to pay the launch costs from deep within Earth's gravity well): https://www.youtube.com/watch?v=gOr-Gd58zu8
Leaving aside the fact the deserts are essential biomes on their own and shouldn't be treated as garbage dumps, didn't Fukishima and Chernobyl teach us that putting nuclear power plants "way over there away from anything" doesn't really matter in the case of a serious accident?
The current level of burning coal equates to roughly 50 nuclear meltdowns a year because coal contains thorium. So in terms of "putting it anywhere," an in-place switch from coal to fission in a populated area is actually safer.
In addition, the article identifies outdated designs as the primary reason for the cost of nuclear plant rollout. Guess what? Modern plant designs are passively safe, particle physics (not electronics, nor mechanics, nor humans) prevents criticality events.
As measured by GHG emissions, nuclear power is certainly better for the climate. Whether or not that equates to "safer for human activity"? The devil is in the details.
If the reactor is passively safe, the amortized level of radioactivity is zero, especially if the waste is "burned" in secondary reactors (such as TWR).
Amortized over the duration where we are typically seeing meltdowns in gen1 reactors. 10-50 years?
The article talks about modern designs. It is an aspiration, not an assumption. The central argument is that adopting modern reactor designs eliminates meltdown concerns (in addition to reducing costs as the article suggests). That isn't an assumption, that is a suggestion.
Sure there is -- one option is a terrifically expensive and dangerous dead end.
We need to focus on figuring out the logistics for the capturing, storage, and distribution of our friendly neighborhood fusion reactor. If you look at the increasing energy density of battery technology over time, there is no practical application for fossil fuels or nuclear in the long run. There are startups that are far closer to the "holy grail" of battery technology than any similar plan for nuclear based power.
The economics are already so clear that every major energy provider is moving to renewables. There is (correctly) no appetite for massive nuclear power plants in anyone's backyard. However, there is already a huge market for putting solar on top of your roof and a battery in the garage.
Tesla has proven the massive savings available to any sizeable government with the use of a truly smart grid. Once the logistics are in place to recycle high performance electric vehicle batteries into infrastructure storage where charging times are less important, it's game over for non-renewables for everything but industrial applications. And there are already solutions for that.
You say this with such certainty... but all of your citations are about renewable and solar. What is your background that gives you the confidence to make such a statement when billions are being spent on nuclear power research by, what I presume you would consider to be, idiots?
I'll stop there because ad hominem arguments are insufficient anyway. The only argument that really matters here is, capitalism will decide the path forward, and not you (fortunately, imo). And the way it does that is that people, none of whom can predict the future with perfect clarity, make intelligent bets about what technologies will produce the most value. As the research and development pans out, the winners become evident, and either way, consumers win.
There's no need to try to strangle the nuclear baby in the crib. If it doesn't work, let it die in development. But, really, how can you make such a confident assertion about the prospects of nuclear? It boggles the mind.
> capitalism will decide the path forward, and not you (fortunately, imo)
Capitalism is the poster child of hubris, and ultimately a fallible set of human ideas -- but that's a different discussion. However, if that is your metric, then the argument is already over.
> how can you make such a confident assertion about the prospects of nuclear? It boggles the mind.
"But even some proponents of nuclear power doubt the program will spur construction of new commercial reactors as long as natural gas and renewable energy remain relatively cheap. 'New builds can’t compete with renewables,' says Robert Rosner, a physicist at the University of Chicago. 'Certainly not now.'
"Ramana [U. of B.C. physicist] questions whether the U.S. nuclear industry can be saved. Although issues of dealing with waste and the public’s apprehension about radioactivity remain, the biggest issue confronting the nuclear industry is the high capital cost of new reactors, which can be $7 billion or more. In deregulated markets, utility companies cannot afford such capital expenses, which is why cheaper renewables may ultimately replace nuclear energy, he says. 'This is a sunset industry,' he says, 'and the sooner you recognize that the better.'
There are competing arguments in the same article, but the argument is between nuclear designs that only exist on paper and wind/solar technology that has already been built and is already providing electricity. If you want to put a shovel in the ground today and have renewable energy in a few months, it's possible with existing solar and wind at prices cheaper than any proposed idea for nuclear.
Of course nuclear physicists want billions of dollars for R&D. Of course they believe they can create the one true design that doesn't have any of the fundamental problems of nuclear technology. But according to those people, even their best efforts won't produce any results for years and years.
To put it into startup language, do you want to build a service using an architecture, language, and set of libraries that have been tested and used for years, or do you want to wait a decade and then start building on the latest holy grail platform that no one has successfully used in production?
I don't disagree that nuclear appears to be on the wrong track, but I've learned that people often conflate doing something wrong with that thing being impossible to do right.
I've been hearing similar stories for the last 30 years.
In that time the energy mix feeding my house has gone roughtly from 50% coal:40% nuke:10% NG, to 30% nuke:30% NG:30% coal: 10% wind. For an increase in total CO2 production, despite a slightly better CO2/MW rating due to moving from coal to NG.
No one AFAIK, has managed to get their "green" energy solutions down to the levels france was in the 1980's, despite the increases in cost that come with not only having to build energy production, but 2-3x the production in storage.
The day its actually cheaper to put solar on your average house with a tesla power wall will be the day there is a shitton of home equity loans being taken out to do so. Or for that matter people knocking on everyones door offering to do it for "free" to sell the power back to the grid.
Right now most of the green energy solutions are "inexpensive" because they are being supported by natural gas generators. Meaning they are cleaner than standalone gas, but still a carbon source.
Residential solar is expensive because you don't have the same economy of scale you see in utility-scale deployments. Also something like 1/3 of the cost is "soft costs" such as marketing and the crazy red tape associated with permitting.
The latest academic modelling shows that we can meet 70-80% of energy demand from renewable energy alone, even without storage. All it requires is building a modest excess of capacity and a 50/50 wind/solar mix. When it comes time to add storage, battery storage costs have been plummeting and already dropped 75% over the last 6 years: https://www.greentechmedia.com/articles/read/report-levelize...
Energy is sufficiently deregulated in enough of the US that they will sell to the areas that aren't, just like France was doing with all its "old dirty" nukes, to the countries around it building "green".
I can't tell from your graph, but I saw an actual cost estimate a couple months ago that points out what has been true for the past 10 years of "wind is cheaper" metrics.
Which is that its not, because its not continuous (or controllable) power delivery. Nor does it account for the fact that it also needs to be overbuilt if its going to supply an energy storage system either. Nor does it account for the energy storage costs.
So, yes in absolute KW produced its cheaper, but that does little but create an oversupply problem. Which is why in places like TX the power costs frequently go to zero when the wind is blowing and spike at other times. Making cheap power when you don't need it doesn't help. What TX needs is lots of power at 3PM (when in theory solar would be useful, but the existing smaller plants aren't making money either).
The net result in TX has been lots of wind install, but even more gas install. Because the gas plants are actually making money. If big battery plants are economically workable then we would also see a lot of companies arbitraging the free wind energy into $ when the price spikes but we don't see that either.
So its not a simple/sure bet like is being claimed.
(for those that don't know, TX is one of the largest green energy systems in the world https://en.wikipedia.org/wiki/Wind_power_in_Texas)
For example, in Ohio several state legislators were purchased, and passed regulation claiming to "save" nuclear but what it really did was bail out coal and prevent the cheapest source of energy from competing in the market. The most surprising is that this corruption is actually resulting in prosecutions, and the top regulator has now resigned too:
Funny you should bring up Texas, it actually is installing massive batteries, with 17GW in the pipeline last time I heard. And natural gas is dwindling to nothing, getting replaced with solar. ERCOT is one of the very very very few places where cheapest cost can actually win, and it's where we are going to see natural gas die first because of that.
Gas plants are still being constructed, and there are more in planning. There is 0 indication its going anywhere anytime soon.
They're generally cheaper to run and better at load-following.
Coal has been on the way out for a decade or so, long before renewable energy started to be a big player in the US.
But, that isn't the point. The point is that even if we go to a ~70% wind model, we will _STILL_BE_WORSE_OFF_THAN_FRANCE_WAS_40_YEARS_AGO_.
The "Green energy" movement there is _INCREASING_ their CO2 production.
I don't get why this is so hard to understand for all those down voters. Worse, at the current rates, we won't get there for decades.
Denmark has about 48% of their energy from wind, and their per capita carbon emissions are at the same level as in 1960. Ireland with 33% is at the same level as in 1980. Portugal with 27% now has the same emissions as 1990.
There is a trend here.
> I don't get why this is so hard to understand for all those down voters.
You are ignoring data that doesn't agree with your hypothesis.
It sure sounds like you were arguing that renewable energy had a time-travel effect causing the construction of gas before the renewables were added?
People are downvoting because what you're saying makes no sense.
You realize that the natural gas plants sit mostly idle when renewables are producing enough power, right? And the more renewable capacity we build, the more often that happens?
> Worse, at the current rates, we won't get there for decades.
So, about the same timespan it took to execute the Messmer plan in France, and at a fraction of the cost? (The Messmer plan was France's big nuclear buildout from the 70s through the 90s.)
On a side note, even if we started building reactors today they probably wouldn't be operational for a decade or more (including planning time).
The market is responding to the inflection point, where renewables are clearly the lowest cost energy.
The switch is happening right now!
I mean, the International Panel on Climate Change certainly thinks renewable energy is a core part of solving carbon emissions. Their special Report on 1.5C AKA SR15 (https://www.ipcc.ch/sr15/chapter/spm/) says:
> In 1.5°C pathways with no or limited overshoot, renewables are projected to supply 70–85% (interquartile range) of electricity in 2050 (high confidence).
For the 3 scenarios where we achieve needed emissions reductions, renewables are 48-60% of electricity generation in 2030, and 63-77% in 2050.
> Energy is sufficiently deregulated in enough of the US that they will sell to the areas that aren't
In the US in 2020 the majority of new generating capacity being added is from solar or wind: https://www.eia.gov/todayinenergy/detail.php?id=42495# -- and if you do the math for capacity factors (around 40% for wind, 25%ish for solar, 60% is for natural gas) then you'll find that solar and wind capacity generates more electricity than the gas.
If the US grid operators and utilities are building all this renewable energy capacity, perhaps they know something...??
> in places like TX the power costs frequently go to zero when the wind is blowing and spike at other times.
Isn't that what a free market is supposed to do -- respond to supply and demand? Last I checked, we don't say that the stock market is broken because it goes up and down.
> that does little but create an oversupply problem
Are you saying free excess power is a BAD thing? I can think of a TON of ways to take advantage of a temporary oversupply; capturing it in storage is only one of them.
> If big battery plants are economically workable then we would also see a lot of companies arbitraging the free wind energy into $ when the price spikes but we don't see that either
Hold your horses -- they're literally starting to do this in Australia. Batteries were pretty expensive up until a couple years ago: https://arstechnica.com/science/2020/10/us-grid-battery-cost...
Now we're seeing a race to install batteries. Energy arbitrage is only one of the possible income streams -- grid services such as frequency regulation are an even bigger source of funds. The "Big Battery" in Australia has already paid for itself after just a couple year and they've already increased capacity by 50% and are installing a second one in Victoria.
> balancing with gas
In the US, gas capacity is mostly replacing dirtier, more expensive coal powerplants. I don't see a problem with using spare gas capacity to help balance the grid while storage gets ramped up -- the renewable generation is directly replacing fossil fuels except when they need an extra boost.
That's a pretty small data point. Check out the worldwide trend.
> No one AFAIK, has managed to get their "green" energy solutions down to the levels france was in the 1980's
The share of nuclear power generation in France peaked around 2005. They had to temporarily shut down four plants in 2018 to avoid meltdowns due to heatwaves which will become more frequent and they are cancelling nuclear projects in favor of renewable projects.
Renewable energy surpassed nuclear for the EU as a whole around 2014. And the first half of this year, renewables provided more energy than fossil fuels:
"It’s official: in the first half of 2020, and for the first time, Europe generated more electricity from renewable sources than from fossil fuels. Not only that, but electricity is proving cheaper in countries that have more renewables.
From January to June, wind, solar, hydro and bioenergy generated 40% of the electricity across the EU’s 27 member states, while fossil fuels generated 34%. In the United States, by way of contrast, fossil fuels generated more than 62% of electricity last year, while renewables accounted for less than 18%."
> The day its actually cheaper to put solar on your average house with a tesla power wall will be the day there is a shitton of home equity loans being taken out to do so.
"Per the US residential solar finance update: H2 2019, a bit over half of homeowners who upgrade their homes with solar panels get a loan, a sixth of the population pay cash, and the last third rent their roof out to a third party.
Within those numbers were $1.35 billion of residential solar loan ABS (asset backed security) 144A public issuances in 2019, doubling 2018’s $680 million."
Shifing to a pacific NW model is economically something that is happening on its own, and has been for the 30 years I linked above. But not because we are building "Green" because all those intermittent sources are 30%+ backed by NG generators which can be spun up/down on demand and over the past 15 are super cheap to install. And NG has been super cheap due to fracking and the fact that the US can't sell it internationally.
But its not about percentages, its about how much CO2 is being produced.
Yes, we get it that you have a wholly irrational dislike of renewable energy and are willing to grasp at straws to argue against it.
> because all those intermittent sources are 30%+ backed by NG generators which can be spun up/down on demand and over the past 15 are super cheap to install
I'm trying to follow what you're arguing here and it makes no sense. You're arguing that the Northwest is simultaneously using almost all renewables and using tons of fossil fuels...? It can't be both.
We'll ignore the fact that according to your link, wind+solar is less than 10% of the electricity generation there, and there's no real evidence of a big investment in either, just the pre-existing hydro power.
That is what got us were we are today. Because back in the 1970/80's people argued the exact same thing (no nukes, solar will save us). And what happened? We got more coal plants because they were way cheaper except in the few places that actually built nukes. The same argument happened in the 1990s/2000s and what did we get? A few percent of wind/solar, and a shift to NG due to fracking.
_TODAY_ if you want a competitive solution you build somewhere in the ballpark of 20-70% wind/solar and back it with NG.
Where will that put us in over the next 40 years?
Its going to create even more C02 because power utilization is going up. All that is going to do is slow the rate of increase, which is exactly what the current charts are showing. The rate of wind/solar rollout is barely exceeding the demand curve and in a lot of places its regressing, particularly in places where ancient nuke plants are being replaced by "green" technologies.
Yes, sure wind+NG is better than NG or coal, but its a shit solution. If batteries actually get cheap then we can do 2x wind+battery, but that isn't here today. What we have today are nuke plants, just like we did 40 years ago. If back then instead of waiting for the future to save us we were more pragmatic the ice caps wouldn't be melting.
My personal opinion is that in 40 years what is going to solve this problem is a giant war, because wishing for the future to save us hasn't worked yet.
I can't even find LCOE figures that far back, but the cost of solar modules in 1975 was just over $100 a watt. Today, a solar panel can cost as little as $0.50/W
That's literally a TWO HUNDREDFOLD decrease in price, and modern panels last longer. This is like arguing that computers are useless in 2020 because in the 70s they were not very powerful.
> If batteries actually get cheap then we can do 2x wind+battery, but that isn't here today
Battery storage costs have already dropped 75% over the last 6 years, and we're pretty close to making that possible:
In the field, people bidding on energy projects are doing mixed solar+storage and wind+storage at prices comparable to nuclear or lower. Today. With 2020 tech and 2020 pricing, not 2025, not 2030. Granted, these aren't including a lot of storage right now (1-4 hours generally) but as battery prices continue to drop that will increase.
Given how costs are dropping as the technologies scale up, in 2025 people won't even think twice before choosing renewables+storage over nuclear, because it'll be a no-brainer.
> What we have today are nuke plants, just like we did 40 years ago.
Yes, that's the problem. Nuke plants plants have advanced technologically in the last 40 years, but in terms of cost they're actually more expensive because we found more failure modes (and need to prevent them).
And this is disappointing because I worked in nuclear physics for a few years and really wanted to believe that nuclear energy was going to save us... and it catastrophically failed to deliver.
This doesn't provide a path to a decarbonized energy sector. It's a good way of mitigating emissions while a real decarbonization solution is implemented. Right now nuclear is the only known way of doing that, save for geographically dependent sources like hydroelectricity and geothermal power.
Multiple countries generate the majority of their electricity from nuclear power. No country generates more than 15% of their energy from solar power, and only 3 countries (Malta, Yemen, Honduras) generate more than 10%.
There's a reason why even though solar is now cheaper than coal it didn't displace it like natgas has.
It wouldn't have been possible to shift to nuclear power overnight either.
Since natgas is 100% dispatchable and is 35% of power generation in the US it's not like nuclear's 20% is really contributing that much stability to the grid right now and natgas can be gradually dialed down as solar/wind/variability tech is dialed up.
Yes... but we just undertook the capex to do this with coal -> natgas in the last decade or so. So the barrier is not just the financial cost of overhauling.
The renewables industry in the US wasn't given any special dispensation so it had to compete pretty much without subsidy with natgas and coal which it could only really start to do about 5 years ago (it's cost competitive with coal only this year).
In fact, arguably the US subsidies oil and gas more than renewables.
Nuclear would require massive subsidies to grow beyond 20%. Renewables won't.
The oil and gas industry is also subsidized at federal and state level, of course.
Solar hasn’t replaced natural gas, because they are entirely different things. It’s exceptionally easy to transport natural gas, it has a ridiculously good energy density and burns well, the logistics of natural gas require no technology in the lines that run between natural gas devices are a half pound of pressure meaning any idiot can hookup/install/modify.
There is a case to be made for hydrogen displacing natural gas, but in my opinion not until we have small local fusion reactors, and in that event you’re probably looking a battery anyway. Hydrogen has great potential for aviation, but home consumer use natural gas will be king for some time.
Rapidly declining, actually.
> they are entirely different things.
Uh, sure - but many of the reasons you're giving seem to be missing that I'm talking about for electricity generation, whereas you seem to be imagining in home usage?
Natural gas power plants can have 1000 psi or more in their lines.
> it has a ridiculously good energy density and burns well
Yes, good energy density - that does sound like something that might be important.
In Hollywood terms, solar/wind/battery plants are now bankable. I don't know who in their right mind would underwrite a nuclear plant now.
Unfortunately this is a very old story with the nuclear industry: they consistently over-promise and under-deliver. The closer projects get to completion, the more costs grow and the further the completion date gets pushed out. This has been true of most of the recent builds in the US and Europe.
The tech is fine, but there seems to be something wrong with the industry.
Their target price, of $55/MWh, would probably be acceptable if delivered today.
But when you look at hybrid solar/battery projects, we are already getting close to $55/MWh for fully dispatchable energy, that doesn't have to be run 24x7 like nuclear but actually matches the load curve of the grid.
Seriously, there are battery projects being deployed now, attached to solar, with a storage cost of $80/MWh, and energy cost of $20/MWh. Since overnight demand is small compared to daytime, only about half of the energy needs to be stored. That averages out to $60/MWh, today. In 5 years it will be something like $40-$50. In 10 years, when NuScale deploys, the cost of solar+storage will be $30-40/MWh. And it might even get cheaper.
NuScale may be useful for polar locations without much wind, but I don't foresee them having a huge addressable market.
They are doing fusion.
Don't get me wrong, I have been pro-fission for a very long time (as it could get us out of this fossil fuel pit faster than any other option, even if we plan to replace it in the future). It has a very bad name because of bad green peace pseudo-science, fusion has better PR.
How does the risk of nuclear meltdown scale down with size? Both in terms of likelihood and how catastrophic?
We're already entering into runaway proliferation.
Pakistan and India are our allies, but I don't see them keeping a stranglehold on the tech. Iran will have them. The Saudis will probably have them soon.
If a dysfunctional nation like North Korea can have nukes, what's stopping the rest of the world?
We're not even preventing ICBM capability from spreading!
What gives? This is way more of a nightmare scenario than climate change and nobody is batting an eye.
there is a probability that an irrational leader orders a nuclear attack and somebody executes it instead of deserting.
climate change is a certainty at this point and the only question is how bad will it be. for people living by the sea and in the parts of the tropics displacement in a single lifetime is next to certain.
