Once again:
1. There has been a lot more action than just "politicians saying things"
2. Politics was the only thing holding nuclear back. Thus the change in the politics is, obviously, significant.
3. Nuclear construction in China is ahead and accelerating.
4. India is not talking, they are building. The 2031 goal is stuff they are in the process of building.
5. Nuclear is cheap. France built its nuclear industry for € 228 billion and got 11000 TWh of electricity out of that. 2,07 Cents/kWh
6. Nuclear is not expensive, but it has been extremely risky, mostly because little to none has been built and also because the best plants are very large. We have now built some, so that's been a tremendous de-risking.
For example, both Ukraine and Poland bought Westinghouse AP-1000 reactors. That's the reactor that just went online at Vogtle-3 and Vogtle-4. So are Ukraine and Poland nuts, buying into a design + company with this track record?
Nope, because those plants have been built, so we know we can build them. And we also know what can go wrong, because pretty much everything did. And we know how to not do the things that went wrong.
For example, one of the biggest drivers of delay and cost was the fact that Westinghouse started building before the plans were actually completely done.
Problem is that that they had to submit those plans to the NRC before they started building. And then build to those plans. In theory, this process is a Good Thing™ because it allows a standardized design to be checked once and then built repeatedly, whereas previously the regulations were ad-hoc per construction, making each reactor a custom build, a one-off with no economies of scale.
Alas, it turns out that the plans they submitted, due to not being complete, were not actually buildable as submitted. Oops. So they had to get almost 200 changes approved, and other times had to tear up stuff they had already built, and start again.
We now have designs for the AP-1000 that are buildable. Because they have been built, Vogtle-3 and Vogtle-4 exist and are delivering power to the grid.
We also built or are building a bunch of EPRs. There, one of the major problems (apart from FoaK and no experience in the industry) is that the design simply is difficult to build. So unlike the AP-1000, no more EPR orders. As a matter of fact, EDF has discontinued the EPR, and instead have created a vastly simplified design the EPR2. Which loses some capabilities, but should be dramatically simpler to build.
So different things went wrong, and thus there are different corrective actions.
