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.
