France Shuts Down Multiple Nuclear Reactors Because of Extreme Heat

France's nuclear power operator announced temporary shutdowns of several reactors. The reductions are a response to unusually high ambient temperatures. Heat stress hampers the ability of cooling systems to maintain safe operating margins. Operators are monitoring reactor conditions closely to prevent overheating. The move underscores the vulnerability of nuclear facilities to climate extremes. Energy authorities assure that the grid will remain stable despite the curtailments. The reactors are expected to resume full output once temperatures normalize. Officials say the situation will be reviewed daily throughout the heatwave.
