Nuclear is about $6k per KWatt. Solar with battery is about $5k per KWatt.
If it’s cost effective to build and maintain a nuclear reactor for $6k per KWatt, then it can also be done with the cheaper solar.

Someone will need to drive that coal to the powerplant and that power plant will need trained electricians. It’s a huge problem!”
