We have new builds in Europe of the EPR, in France and Finland, and it has had disastrous costs. China has built some too, presumably cheaper, since they keep on building more. What is the regulatory difference there?
I have yet to find any concrete defense of the idea that costs are coming from regulation, rather than the costs of construction in advanced economies.
If regulations are the cost, name them and a solution. Otherwise it seems like we are wasting efforts in optimizing the wrong thing for nuclear.
Just look at building costs in California vs Texas. Both are nominally constituents of the same "advanced economy".
I have a whole host of clearly specifiable changes to California building law that will make it cheaper, and am actively working on them both locally and at the state level! This is clear!
As somebody who is very interested in making Calforina housing cheaper, and in particular housing construction cheaper, it is my duty to say what should change, why, and convince others of it.
If I go out and advocate for "change" without being able to specify a single change, I would get jack shit done. It doesn't work that way.
Every single nuclear advocate that I have ever met that says "regulations should change" can still not yet specify how those regulations should change. That's the minimal bar for holding an opinion.
Reading the DoE LPO report on how nuclear can scale up and get cheaper, it wasn't regulations doing the work. It was learning how to build.
