A MW of solar averages out to about .2 MWh per hour. A MW of nuclear averages about .9 MWh per hour.

But even so as the UK does it, nuclear power isn't worth it. France and China are better examples since they both picked a few designs and mass produced them.

China's experience indicates you can mass produce nuclear relatively cheaply and quickly, having built 35 out of 57GW in the last decade, and another 88GW on the way, however it's not nearly as quick to expand as solar, wind, and fossil fuels.
