Opposing the Golfech Restart: Climate Vulnerability Exposes Nuclear's Limits

While the restart of the Golfech reactor may seem like a routine return to normal, it underscores a deepening problem: nuclear power is increasingly vulnerable to the very climate change it is supposed to help mitigate. Heatwaves are becoming more frequent and severe, and France's river-cooled reactors—like Golfech—are forced to shut down or reduce output just when electricity demand spikes for air conditioning. The 17-day outage is a symptom of a brittle system that relies on abundant, cool water. Rather than rushing to restart the same vulnerable infrastructure, France should accelerate investments in diversified renewable energy—solar, wind, and storage—which are less dependent on water and can be distributed across regions. Moreover, restarting nuclear plants after heatwave events often involves restarting the discharge of warm water into rivers, potentially harming aquatic ecosystems during already stressed conditions. The urgency to restart also reflects a lack of demand-side management: why not invest in energy efficiency and smart grids to reduce peak demand instead? Critics argue that rebuilding and extending the life of ageing reactors faced with climate risks is a costly gamble. Opposing the uncritical restart means calling for a real energy transition, not just a temporary fix that kicks the can down the road. France must face the reality that its nuclear-centric model needs fundamental rethinking.
