Correct. France built its reactors after the oil crises of the early 70s to guarantee its energy independence. The irony being those same plants failed at the time of the biggest energy crises since then.
They failed. A quarter was out because of faulty pipes and another quarter was out because of planned maintenance. France had to rely on its neighbors to keep its lights on, and became a net importer of electricity for the first time in decades. And I repeat during the biggest energy crisis in 50 years, which was the entire reason for their existence. Can't fail in a worse way.
They didn't fail.
