Standard nuclear designs are still too costly, and safety features are only a third of nuclear costs.

Ars Technica 21st Nov 2020, Should any discussion of nuclear power go on for long enough, it becomes inevitable that someone will rant that the only reason they’ve become unaffordable is a proliferation of safety regulations. The argument is rarely (if ever) fleshed out—no specific regulation is ever identified as problematic, and there seems to be no consideration given to the fact that we might have learned something at, say, Fukushima that might merit addressing through regulations.

But there’s now a paper out that provides some empirical evidence that safety changes have contributed to the cost of building new nuclear reactors. But the study also makes clear that they’re only one of a number of factors, accounting for only a third of the soaring
costs. The study also finds that, contrary to what those in the industry seem to expect, focusing on standardized designs doesn’t really help matters, as costs continued to grow as more of a given reactor design was built.
