Heatwave cuts power from nuclear plants
The heatwave is affecting nuclear power in Switzerland as the river waters used to cool the reactors are too warm.
The power plant at Muhleberg uses the water in the Aare River to keep its generators cool – but the sun is heating the water which makes it less effective. Power generation is being cut to reduce the strain on the river.
In Bern the river has reached 22 degrees – great news for swimmers, bad news for power stations. That temperature is very unusual in June.
