The French energy supplier EDF is temporarily reducing output at its nuclear power stations on the Rhône and Garonne rivers as heatwaves push up river temperatures, restricting its ability to use river water to cool the plants.
The majority-state-owned company, Europe’s biggest producer of nuclear energy, said it would extend output cuts at several power stations on the two rivers as the hot spell continues – but that a minimum level of output would be maintained to keep the grid steady.
