Yeah I hear this every time, but very few small modular reactors (SMRs) have actually been built on account of economic and safety barriers to building them [1].
Now, I'm sure these are soluble problems. I'm by no means anti-SMR. But most of the actual serious proposals I've heard discussed for decarbonization lean much more heavily on already-existing technologies such as solar panels, which are getting cheaper and more efficient every year and which we are putting in the grid right now.
Most of the time, when I hear people talking about SMRs, it's as an excuse to do nothing. "This research tech will solve the climate problem, so all we need to do now is wait for it to pay off." Like the original poster in this thread, who claimed that a lack of investment in nuclear somehow proves that things aren't really that bad.
Apparently, the IPCC does expect and hope for substantial increases in nuclear power as a portion of our energy supply [2][3], but "[a]chieving a rapid decarbonization of the electricity sector will require, at first, deploying proven technology," presumably because nuclear on its own is not enough, and because SMRs are too experimental to lean on in any substantial way.
