Then surely when they started pushing back on Yucca Mountain opening up, the federal government could have just bought one of the many mines that no longer produces, right? Why hasn't that happened? There are 49 other states that could, in theory, be bidding on a contract to house nuclear waste. There are some states that have a large amount of land relative to their population too.
For the record, this thorium reactor waste isn't harming anyone in Colorado, but they've also refurbished the plant in to a natural gas power station and it's still actively run. Should that be decommissioned, then I'm not entirely sure what it costs to maintain the waste storage facility. They're adding a couple new turbines to this plant so I expect it has a decently long life ahead, but what happens in like a century if DoE doesn't move this waste?
Regardless of the engineering, and I think we've made tremendous advances in nuclear design and have much better safety than before, I think it's more than low-information voters and regulatory issues, fundamentally we don't have a strong answer for the waste. A nuclear powerplant has a relatively fixed production life, but there is no end to the cost life.

Because the topic is politically contentious. It doesn't matter which new site is floated or who proposes it when there's effectively blind opposition without regard to technical merit.
The reality is that for any objectively defined risk metric we can come up with a solution that involves burying it in the ground at some depth and in a certain sort of surrounding geology. At some depth it ceases to matter despite what the activists seem to think.
"At some depth it ceases to matter despite what the activists seem to think."
Yes, but to be really safe, that point might be so low, it becomes really expensive, also getting it all there without accident - which is the whole point, of course radioactive waste can be treated safe and sound - but that is expensive and people and companies and governments are known to be sloppy.
Sure but the limited volume really puts an upper bound on the expense. You could package it in containers small enough for a single person to carry and then have people individually walk them down to the bottom of the mponeng mine and it would still be reasonably affordable.
It's an absurd thought experiment to illustrate that even when taken to an extreme the volume is small enough that a solution broadly remains feasible.
In germany alone, 500 000 m³ of radioactive material is to be disposed somehow by 2050. Having people carry that underground sounds insane. There is more to waste than fuel rods. And even they .. amount to a really high number if you factor in shielding.
I think you have a serious misconception. The long term storage we're talking about here is for the spent fuel rods (or alternatively the byproducts extracted from them if they are reprocessed). It's known as high level waste and there isn't very much of it.
> As a general rule, short-lived waste (mainly non-fuel materials from reactors) is buried in shallow repositories, while long-lived waste (from fuel and fuel reprocessing) is deposited in geological repository.
> Overall, the 60-year-long nuclear program in the UK up until 2019 produced 2150 m3 of HLW.
