France heat wave prompts nuclear plant output cuts

A prolonged heat wave across France has led to record high temperatures, with the 20th consecutive day of extreme heat reported in the Saône‑et‑Loire region. Distant thunderstorms were observed, but the cloud cover is expected to trap heat overnight, sustaining the high temperatures.

Infoclimat noted that several French nuclear power plants have been forced to reduce or temporarily halt production because of insufficient water for cooling, a direct consequence of the drought conditions. The situation underscores the broader impact of the heat wave on energy supply and public health.
