How come Sweden as cheap nuclear power? The main reason electricity is kinda expensive in Sweden is because the EU forces is to export our cheap nuclear energy to Denmark and Germany.
Paid off nuclear plants produce quite cheap electricity. The problem is that it takes 10-15 years of building and then 40 years of paying $180-220/MWh to get a paid off nuclear plant as per modern western construction costs.
Subsides, the cost to produce electricity and the cost charged for that energy end up very different.
