Europe's recent extreme heatwaves have forced several nuclear power plants in France, Romania, and Hungary to reduce output or shut down temporarily due to environmental limits on cooling water temperatures and water availability, highlighting operational challenges for nuclear energy in a warming climate.

This Wire brief sits within Fusion42's coverage of Energy Storage.

◆ ◆ The Wire takeaway

Nuclear plant operators must prepare for stricter environmental limits and reduced cooling water availability as heatwaves worsen. If you build or operate thermal plants, adjust designs and operations now to avoid frequent output reductions during heat stress.
