France's state-owned energy giant EDF has temporarily shut down two of its nuclear reactors, located at Nogent-sur-Seine and Bugey, as the country grapples with a record-breaking heatwave. The decision to halt operations at these facilities is a precautionary measure taken to comply with environmental regulations concerning the temperature of water discharged from the plants. Rising river temperatures, exacerbated by the intense heat, pose a risk of exceeding the permitted thermal discharge limits, which are in place to protect aquatic ecosystems. EDF is monitoring the situation closely and will resume operations once river temperatures return to acceptable levels, ensuring compliance with environmental protection standards.
