The heatwave across Europe in late July required some nuclear plants to reduce electricity after cooling water was affected by high temperatures. Plants in Finland, Sweden, Germany, France and Switzerland have been affected. While air temperatures have been above 90 degrees Fahrenheit (32 degrees Celsius) in many parts, water temperatures have reached 75 degrees Fahrenheit (23.8 degrees Celsius) or more. The Loviisa nuclear plant, which produced 10% of Finland’s power in 2017, began reducing its output on 25 July, according to chief of operations, Timo Eurasto. He said customers were not affected, because other power plants were satisfying electricity demand. Loviisa previously reduced output in 2010 and 2011, due to warm water, but Eurasto said the current heatwave has been more severe. Reactors in Sweden and Germany also reduced production because of cooling problems, Reuters reported. A spokesperson for Sweden’s nuclear energy regulator said the Forsmark had cut energy production “by a few percentage points”.

The nuclear industry has highlighted its role in the UK’s future energy mix, as new government figures showed that low-carbon electricity produced in 2017 rose above the 50% mark for total power generated. The owners of Suffolk nuclear power station Sizewell B and the proposed Sizewell C plant pointed out that nuclear energy had been a reliable source of power during periods of high demand and low wind. The 50.1% percentage share, up from 45.6% the previous year, consists of 21% nuclear, 14.8% onshore and offshore wind, 3.4% solar and 2.3% hydro. Trade association the Nuclear Industry Association (NIA) said nuclear power remained “the highest single source of low carbon power delivering reliable, secure and always available power to the grid whatever the weather”.
