What I wrote is and has been an actual topic of real world politics here.
There is nothing speculative or questionable about it.
Nuclear reactors are not flexible. To keep them in any way financially sane, you have to keep them running as long as possible. Even when the energy they produce is much much more expensive then the one from renewables. This is why they block the grid an renewables had to be turned off.
It ain't me.
As one example of many see previous post on nuclear production records.
