Just for clarification, do you mean life cycle analysis by 'energy life cycles'?

Looks like I do. Policy is not my native language.

I thought the main reason we haven't seen a lot of nuclear expansion, other than public pushback, is the rapidly increasing costs with decreasing magnitude of construction; you either need to build a dozen at a time, or none at all.

In the US, at least, the fact that you can't build a reactor without it being a megaproject means that you never get an accurate cost assessment from the get-go. And, since you're now talking about a megaproject with giant cost-plus contractors and little competitive bidding operating under a dozen different regulatory entities, you're talking about epic graft and corruption.

France gets around this through nationalization. Notably, electricity in France is about 30% more expensive than in the United States, which is still the cheapest in Europe. But then, that's what happens when you win The Great Game: you force everyone else to spend more on resources.
