What you wrote there would be true if the levelized cost of energy from nuclear weren't so high. As it stands, the dirt cheapness of renewables (and particularly of renewables as they will be a decade in the future as they continue down their aggressive experience curves) will make dealing with intermittency cheaper than going with nuclear.

It could make sense to continue to operate existing nuclear power plants while taxing carbon emission, but the CO2 tax needed to justify new nuclear plants would be outrageously high. Long before that level of tax was reached renewables would snipe the market.
