Nuclear is too expensive to run in the short term. Nuclear plants only start being profitable after like 10 years. But then they’re really fucking profitable. So it makes sense a company could go bankrupt when you’re 10 years in the red.
Also, on the topic of flexibility, this is only true for, like, 70s era nuclear. France has had load-following nuclear for some time now. Does it follow second-to-second variations? No, but it can load follow on the scale of the daily variations in demand.
I am also aware that they are spelled the same, but I consciously use a U only for the organism.
For what it’s worth, I’m Canadian, so nobody would bat an eye here at using either the American or British spelling of things.
