Is it worth the price of energy sovereignty though? You are not just buying electricity, you are buying future independence. It might be worth it if you factor that in.

And don’t forget all the other expertise that comes from being a country that is able to build reliable nuclear reactors. China is _the_ production superpower not just because it can build x or y, it’s because it has all the supply chains to be able to do it at scale.

If a country invests into that expertise - you get a lot of very capable engineers, a lot of tech and supply chains to deal with making it all happen, again and again, at scale. That in itself would be something that can offset the raw “price” of a single reactor, though it is very hard to quantify.

Like how much has USA actually lost by relinquishing its historical role of guarding international trade? Maybe it won some independence, but maybe the upstream effects to its economy would be bad?

We don’t know for sure about nuclear, but when a similar scientific project was put on a national scale - the space race - USA got silicon valley out of it.
