Nuclear power stations are built solely for the purposes of supporting a nuclear military (like in Russia, the USA or France) or building nuclear weapons in a hurry (like in Sweden, Iran or South Korea).
No country does it for any other reason. Certainly not for the environment. The cost is absolutely prohibitive (5x solar/wind) and it demands lavish subsidies even if you discount the nearly free government-granted catastrophe insurance.
The only way to make it cheap for the consumer is to have paid off the plants because they were built 50 years ago and to neglect their maintenance. Like France.
Pumped storage, solar and wind meanwhile, are very, very reasonably priced.
