“Distributed micro-nukes are the way to go.”
I don’t know if you’re talking the same as Small Modular Reactors (around 77 MW), but their cost per watt is now matching traditional US nuclear plant cost. Seems that every large project gets more expensive as it gets closer to reality.
The reactor comes in on a truck. When it's spent, bring in another and take the first back to the factory for reconditioning.
