“”France has restarted its entire nuclear fleet after emergency maintenance …
The years 2022 and 2023 were the most difficult in the recent history of French nuclear energy. An unprecedented wave of stress corrosion cracking discovered in the cooling circuits of multiple reactors forced simultaneous outages across a large fraction of the fleet …
EDF’s industrial recovery program … systematically inspected, repaired, and restarted the affected reactors over an 18-month period. By late 2023, the French fleet was back above 80% availability. By 2024, it was approaching historical norms of 85 to 90% availability. …
The stress corrosion episode taught French nuclear operators lessons about inspection frequency, material selection, and maintenance planning that have been incorporated into revised operating protocols. The fleet that has emerged from the crisis is better monitored, more thoroughly inspected, and operated with greater margins against material stress than at any previous point in its history.
France’s nuclear fleet went through its hardest years. It came out stronger.

This is the first that I have heard about this French nuclear plants issues and shutdowns — it’s been more than 3 years! It seems to me that the nuclear industry has tried to keep it quiet — it is a black eye on the nuclear industry as a whole. This disappoints me because the public needs to be kept informed. Of course the NIMBYs will make a big thing about it. But even so, that’s the point of news media – to keep the public informed. This problem – cracks in the cooling system – was what happened with the San Onofre nuclear reactors and they shut them down and spent a hundred million to replace the cracked cooling system. But then it happened again! So they gave up and permanently shut San Onofre down and it is costing hundreds of millions of dollars to decommission San Onofre nuclear.
