Small nuclear reactor advocates refuse to learn the lessons of the past

While history doesn’t repeat, merely rhymes, SMRs are rhyming hard

Like hydrogen, small modular nuclear reactors have been seeing a resurgence of interest lately. Much of that is driven by governmental policies and investments focusing on the technology. Much of it comes from the nuclear industry. And inevitably, some comes from entrepreneurs attempting to build a technology that they hope will take off in a major way, making them and their investors a lot of money.

Small modular reactors won’t achieve economies of manufacturing scale, won’t be faster to construct, forego efficiency of vertical scaling, won’t be cheaper, aren’t suitable for remote or brownfield coal sites, still face very large security costs, will still be costly and slow to decommission, and still require liability insurance caps. They don’t solve any of the problems that they purport to while intentionally choosing to be less efficient than they could be. They’ve existed since the 1950s and they aren’t any better now than they were then.

Most of the attention and funding is misguided at best, and actively hostile to climate action at worst
