They are also built and run by public or quasi-public utilities. I don't think we have a lot of examples of the private sector building nuclear generating plants. Maybe they can do it better, when it's their own money on the line, and they don't have a legally granted monopoly protecting them.

Privatizing electricity in California resulted in massive underinvestment and forest fires as a result of poor maintenance.

Privatization only saves money if you ignore the price paid by surrounding communities.

I would not like to see a fully private nuclear plant.
