French authorities temporarily shut down a reactor at the Golfech nuclear power plant near Toulouse due to extreme summer temperatures, according to multiple reports. The shutdown follows ongoing unusually hot weather across Europe, with France experiencing a severe heatwave. Officials cite the impact of very high ambient temperatures—reported as around 28°C in one account—on operating conditions at the facility. The reactor is taken out of service as a precaution while conditions remain unfavorable. The reports describe the decision as unusual, emphasizing that heatwave conditions are affecting the plant’s ability to run. No information in the provided accounts specifies the reactor’s unit number, the exact duration of the shutdown, or whether power generation disruptions include broader impacts beyond Golfech. The accounts converge on the core point that extreme heat linked to the heatwave is prompting emergency-style operational adjustments at the Golfech site.
