Powerful nuclear reactors taken offline as France faces record heatwave

SMRTR summary

France shut down several nuclear reactors during a record heatwave after river temperatures rose too high to safely discharge cooling water back without harming wildlife. The shutdowns reduced nuclear output by around 4 gigawatts, roughly seven percent of demand, pushing wholesale electricity prices in France and Germany to their highest levels since early 2025. Despite the disruption, grid operators say electricity supply remains sufficient.
