Why are nuclear crops so costly? Security’s solely a part of the story

Enlarge (credit score: US DOE)
Ought to any dialogue of nuclear energy go on for lengthy sufficient, it turns into inevitable that somebody will rant that the one motive they’ve turn into unaffordable is a proliferation of security rules. The argument is never (if ever) fleshed out—no particular regulation is ever recognized as problematic, and there appears to be no consideration given to the truth that we’d have discovered one thing at, say, Fukushima which may benefit addressing by means of rules.
However there’s now a paper out that gives some empirical proof that security modifications have contributed to the price of constructing new nuclear reactors. However the research additionally makes clear that they are solely one in all plenty of elements, accounting for less than a 3rd of the hovering prices. The research additionally finds that, opposite to what these within the trade appear to anticipate, specializing in standardized designs would not actually assist issues, as prices continued to develop as extra of a given reactor design was constructed.
Extra of the identical
The evaluation, achieved by a workforce of researchers at MIT, is remarkably complete. For a lot of nuclear crops, they’ve detailed building information, damaged out by which constructing completely different supplies and labor went to, and the way a lot every of them price. There’s additionally an in depth document of security rules and after they had been instituted relative to building. Lastly, they’ve additionally introduced within the patent functions filed by the businesses who designed the reactors. The paperwork describe the motivations for design modifications and the issues these modifications had been supposed to unravel.Learn 16 remaining paragraphs | Feedback
