Next week, nuclear production will be affected by high temperatures in the French River

Nuclear operator EDF announced in a Friday notice that high water temperatures will affect electricity production along the Rhone River in eastern France starting June 25. This is especially true at the Bugey nuclear power plant with a 3.6 gigawatt capacity.

The first warning of high temperatures on rivers in France for 2025 is here. Heatwaves can impact the environmental regulatory thresholds for cooling water going through the system, and then being discharged.

Meteo France's data shows that a heatwave will sweep across France this weekend. Temperatures could reach as high as 38 deg Celsius (100.4degF), in the south.

The bulletin did not mention the 3.6 GW Cruas Nuclear Plant and the 2.6 GW Saint-Alban Nuclear Plant, which are downstream of the Bugey nuclear plant.

Currently, one of the 1.3 GW units at Saint-Alban as well as one of the Cruas reactors are offline for maintenance.

EDF is able to lower production in individual reactors, rather than shutting down the entire nuclear plant. This means that if a reactor needs maintenance, the reactors currently operating will not be affected.

The summer months are usually the maintenance period, as power demand is lower. Reporting by Forrest Krellin, Editing by Tomasz and David Evans
