EDF posts record loss in France due to reactor outages

I've recently been made aware if the corrosion problems that were discovered in French reactors in 2022 - which were alarming, and induced the shut down half their plants[0]. Even a few months ago massive cracks were discovered in one reactor[1], raising concerns for other similarily constructed plants.

I've also found articles posted here showing that hotter summers forces them to lower production - otherwise wildlife begin to suffer in the rivers used to cool the plants[2].

I am very suprised that this is something I was not at all aware of. Not being an expert at all on the subject, could anyone weight in on the seriousness of the situation?
