France’s main electricity provider, EDF, temporarily shuts down three nuclear reactors as a heatwave reduces available cooling capacity and raises river temperatures. According to reports, the shutdown affects reactors at three French nuclear plants, while eight other reactors continue operating but at reduced power. The action is linked to environmental protection rules that limit how much heated water EDF can discharge into rivers already affected by unusually warm conditions.
Multiple outlets describe the same rationale: cooling needs increase during hotter weather, and releasing excess warm water into rivers could worsen local ecosystem impacts. By lowering output and, in some cases, stopping reactor operations temporarily, EDF aims to stay within permitted discharge limits and reduce thermal stress on waterways.
The measures are framed as temporary and precautionary, tied directly to the heatwave’s effects on cooling water and river conditions. No reports among the sources provide details on the duration beyond indicating it is linked to current weather and regulatory requirements.
