Nuclear construction is not limited to 100 MW/year. The new Texas reactors will result in 1356 * 2 MW in 9 years and that is only one site. That is from announcement to commercial. Actual construction might be say 5 years per plant and we could easily construct many plants at the same time with existing infrastructure. We could probably put more than 8000 MW of capacity on-line each year.
You're right, I'm comparing apples and Fords. :P
Sorry!
