Actually that doesn't seem to be true of the one in Iowa. But it's only a 585 unit. So maybe you are thinking of putting a 1gw unit in every city. Every city of what size? What about excess production. How much does electricity cost when you have to build enough nukes to handle the highest peak but said nukes spend a lot of their time idle or at less than peak power?
Once again you’re playing the willfully ignorant game. Of course the Iowa nuke plant, like all the other nuke, gas and coal plants on the planet, has redundancy so they can do maintenance.
Cities ALREADY have plants, the problem right now is they’re mostly coal or gas, polluting, beholden to foreign powers for fuel, and not as efficient as possible. And they aren’t spending time idle, there you go spreading that lie again.
