It's ridiculously uneconomic of course but a limited number will continue to be built in spite of this because of the overpowering military imperative.

If you have nuclear weapons/submarines/carriers/etc. like Russia or the United States or France it shares some of the gargantuan cost of building and maintaining them. I expect North Korea will get into it in the next few years too for precisely this reason.

Countries like Iran, Sweden and Korea, on the other hand, want to be able to manufacture a weapon on a tight deadline because of extremely self evident geopolitical fears.

Nobody else builds nuclear power plants. The vast power of the global hippy-industrial complex apparently prevented it :/

Of course, the western nuclear military industrial complex, who always HATED environmentalists with a seething passion, are aware of just how massively uneconomic it is but that doesn't stop them from trying to dress up as "young climate activists" to sell a form of power that is 5x more expensive as a green gamechanger. Consent for enormous subsidies needs to be manufactured somehow if nuclear power is to remain competitive with solar and wind.

Commercial reactors and military/medical isotope reactors are usually completely separated. The reason for that is that BWR/PWR reactors don't let you manipulate the fuel while the reactor is working, which makes it considerably harder to get plutonium.
