Heatwave Slashes French Nuclear Power Output
13 Jul
Summary
- French nuclear output dropped by 6.3 GW.
- Eight reactors were affected by the heatwave.
- High river temperatures limited cooling water use.

As of Monday morning, France's nuclear power generation experienced a substantial reduction of 6.3 gigawatts. This decrease affected eight different reactors, a direct consequence of a prolonged heatwave gripping the nation.
Elevated river temperatures were identified as the primary cause for the output cuts. The extreme heat limited the ability of EDF, the operator, to utilize river water for cooling purposes at its nuclear facilities. This situation highlights the vulnerability of energy infrastructure to extreme weather events.
