The Beznau nuclear power plant in Switzerland temporarily suspended operations due to the ongoing heatwave, the operator announced Friday evening. The facility, Switzerland's oldest nuclear plant and one of Europe's oldest, was shut down as a precautionary measure linked to high temperatures affecting cooling water conditions.
The Beznau nuclear power plant (KKB) in Switzerland canceled its operations due to the ongoing heatwave, the plant operator told press on Friday evening. The facility, located in the canton of Aargau on the Aare river, has two pressurized water reactors with a combined capacity of roughly 700 MWe. Cooling water temperature limits set by Swiss nuclear safety regulations require the plant to reduce or suspend output when water temperatures rise above thresholds, a standard measure to maintain safety margins and avoid environmental damage to the river ecosystem. This is not an emergency shutdown. The operator said power production would resume once temperatures drop and river conditions return to normal. Beznau, which began commercial operation in 1969, is among the world's oldest nuclear plants still in service.
