That depends entirely on what design you go with. Ideally we would be looking at municipal level power generation with modern proven light water Small modular reactor designs reliant on passive safety features we can pump them out of factories at a rate of approximately two per day if we can look at the average aerospace industry rate of construction for jumbojets for a comparable engineering project in size and scope to most SM reactors.

There are also many options to convert existing fossil-fired plants to be nuclear powered at the end of the day a turbine spinning is a turbine spinning. It doesn’t care whether you boiled the water with radiation or coal or oil or gas
