Why France shuts down its nuclear reactors during heatwaves
Briefly

France's reliance on nuclear power leads to reactor shutdowns during high summer temperatures. The Golfech nuclear reactor was shut down when the nearby River Garonne reached unsafe temperatures for cooling. Other reactors, including those at Bugey and Blayais, have reduced power output as well. Routine shutdowns occur to comply with environmental regulations aimed at protecting local ecosystems. French nuclear infrastructure must adapt to increasing summer heat and frequent heatwaves to ensure stable electricity production while maintaining environmental safety.
EDF announced it had shut down reactor 1, the only one currently active on site, due to rising water temperatures in the River Garonne, reaching 28C.
Other reactors, such as Bugey and Blayais, have had to reduce output as summer temperatures rise, affecting the functioning of various nuclear plants.
Open-loop nuclear power plants are first to be affected during heatwaves, requiring substantial water for cooling, which becomes limited during such temperature extremes.
Shutdowns during heatwaves are routine processes aimed at complying with environmental regulations, which prioritize the protection of local ecosystems over nuclear safety.
