Hind Al Soulia - Riyadh - BRUSSELS — Due to a scorching heatwave which has spread across Europe in recent days, a number of nuclear power plants in Switzerland and France have been forced to either reduce activity or shut down completely as extreme temperatures have prevented sites from relying on water from local rivers.
To cool down, nuclear power plants pump water from local rivers or the sea, which they then release back into water bodies at a higher temperature.
However, Europe's ongoing heatwave means that the water pumped by nuclear sites is already very hot, impacting the ability of nuclear plants to use it to cool down. On top of this, nuclear sites run the risk of posing a dangerous threat to local biodiversity, by releasing water which is too hot into rivers and seas.
In light of the heat, Axpo - which operates the Beznau nuclear power plant in Switzerland - said it had shut down one of its reactors on Tuesday, adding that a second reactor was operating at limited capacity.
"Due to the high river water temperatures, Axpo has been increasingly reducing the output of the two reactor units at the Beznau nuclear power plant for days and reduced it to 50 per cent on Sunday," said the operator.
The Beznau nuclear power plant's reactors are located directly on the River Aare, where temperatures have reached 25 degrees Celsius in recent days, leading Axpo to curtail its activities to prevent "excessive warming of the already warm water" which could strain local biodiversity.
Although Switzerland has decided to phase out nuclear power by 2033, existing plants are able to continue to operate as long as they are safe.
Meanwhile, on Monday French electricity company EDF shut down the Golfech nuclear power plant, located in the southern department of Tarn-et-Garonne, amid extreme heat warnings in the region and concerns that the local river could heat up to 28 degrees, even without the inflow of heated cooling water.
France has a total of 57 active nuclear reactors in 18 power plants. According to EDF, the country obtains around 65% of its electricity from nuclear energy, which the government considers to be environmentally friendly.
Output has also been reduced at other sites, including at the Blayais nuclear power plant in western France, as well as the Bugey nuclear power plant in southern France, which could also be shut down, drawing their cooling water from the Gironde and Rhône rivers.
Although the production of nuclear power has had to be curtailed in light of extreme heat, the impact on France's energy grid remains limited, despite the fact that more electricity is being used to cool buildings and run air conditioning systems.
Speaking to broadcaster FranceInfo, French grid operator RTE ensured that "all the nuclear power sites which are running are able to cover the needs of the French population. France produces more electricity than it consumes, as it currently exports electricity to neighbouring countries."
However, experts forecast that peaks in energy consumption peaks during heatwaves will only become more frequent, as global temperatures continue to rise. — Euronews
