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.
Cutting regulations isn't necessary the win people think. If safety regulations are cut, it risks accidents in future.
Nuclear needs to move from bespoke builds to serial production.
The actual situation was that relentless 7%/year demand growth for electrical energy suddenly stalled, while at the same time a large amount of new capacity from cogeneration, made possible by the passage of PURPA in 1978, suddenly started to come on line. In this environment, and with the cost overruns and delays of the earlier nuclear builds, utilities could not make a case for new nuclear construction. High interest rates also didn't help.
