Not specifically nukes. Any power source without huge seasonal or day-to-day variability will do. But we are going to need a lot of it.

But nukes has a somewhat unpredictable security variation which forces them to quickly go off line from time to time.

However, what matters is not the variability of the individual plant, but of the system as a whole. So lots of wind over a large area - say Europe - should do the trick, and so should lots of nukes over Europe, or lots of wind and nuke over Europe.
