You forget another cost: hard dependency (= "Soft Power"). Sure, selling uranium rods might not be as lucrative as other things. But e.g. France is completely dependent on uranium rods for their grid not to go dark, so the very few countries who sell those have a lot of political influence over them. Like Russia.

Russia had Europe at their balls with energy almost completely (Uranium, Oil, Gas) which is one reason why they thought they could get away with even starting the invasion of Ukraine. The price shock for energy in Europe was brutal in 2022, one of my best friends here in Germany had their heating bill quadruple because it was Gas, thereby lost their home and "temporarily" lived on my couch (for 2.5 years). Meanwhile France ALSO had to scramble finding another provider of Uranium rods, which are quite rare. This caused them having even more issues than Germany over a longer period of time, which sounds absurd given Germany famously made themselves almost completely dependent from Russian gas.

Right now nuclear only goes up in price, running cost and thereby electricity costs. The idea of building some new ones can really only be justified in terms of CO² output in a combined strategy with renewables, nothing else. And at least in regards to the awful dependency thing and crystal clear cost calculations every politician of any country should be on the same boat. Unfortunately a lot of them replaced their brain with various other stuff.

Russia has a lot of control over all layers of nuclear power, so this gives them political leverage.
