Switzerland's Beznau nuclear power plant, Europe's oldest reactor, has fully resumed operation following multiple shutdowns caused by summer heatwaves affecting its cooling river. The plant, which provides about a tenth of Switzerland's electricity demand, had to reduce output due to high river temperatures impacting reactor cooling.

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

◆ The Wire takeaway

You face fresh questions about cooling risk as heatwaves disrupt nuclear output. Prepare for tighter operational plans and alternative power sources during extreme weather.
