Extreme heat and low river water levels are forcing European nuclear power plants, especially in France and Hungary, to reduce output temporarily to protect local ecosystems, affecting short-term electricity supply and market stability. France plans to modernise its nuclear fleet with more coastal EPR2 reactors to better handle climate change impacts on cooling capacity.
