French reactors are all the same design (derived from one licensed from Westinghouse). That's how they got the economies of scale and were able to ramp up so quickly. Unfortunately, that also means a flaw is reproduced in all of them. To compound this, the replacements were not started quickly enough so the current reactors are reaching the end of their design life, and because there was not a program to continuously build bew reactirsm the industrial skills base atrophied as qualified workers like welders retired. And the trifecta is France is experiencing its worst drought in recorded history, so some of the plants that get cooling from river water had to shut down due to low water levels. Even the mighty Rhine is a mere rivulet at the moment.
