> several nuclear reactors were taken down for a scheduled maintenance To add to everything you said, the Covid crisis also impacted maintenance, delaying repairs by about a year (source: I've got surprisingly many friends/colleagues coming from the CEA, the French Atomic Commission) Also, EDF lost a lot of knowledge and manpower during past decades, (most? at least many of) people working on nuclear plants are now sub-contractors, that impacted stability.
