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.

MW/h

There is MW which is a unit of power and then there is MWh which is a unit of energy, but what is MW/h supposed to mean?

Thanks for catching the typo.

Maybe just use percentages instead of these weird units. 0.2 MHh per hour is just 0.2 MW, or 20%.

It seems easier to say solar produces an average of 20% of it's peak capacity.

Nuclear actually around 0.6, because 1/3 is always off for repair and control.

Maybe in the UK where each plant is basically unique instead of having improvements from all the previous iterations. In the US it's around 93%. I don't know how to search China or France's numbers, but I suspect they're similar or better.

My observations are from France, germany, switzerland though. Maybe we are a bit more careful and by-the-protocol here, who knows.

On the other hand, rarely has one more than 3 blocks here, and a colourful mix of generations. You might be right.

In many regions solar capacity factor is much higher than 20%; for example, the entire US. https://atb.nrel.gov/electricity/2021/utility-scale_pv
