When I read here about nuclear as a solution I never read about how much fuel there is left, where it comes from, how much CO2 digging up the fuel and processing it is created as well as the waste management.

The waste is not a solved problem. In Germany we have huge problems with it hence why nuclear is on the way out.

Nuclear in France had problems with running during the summer due to the water in rivers being too hot and the system not maintaining the correct temperature difference.
