Hungary is sinking two barges to ensure a key nuclear power plant stays online, Prime Minister Péter Magyar said Saturday.

 

Europe’s summer of extreme heat has caused the Danube’s water level to hit record lows, affecting power production at the Paks nuclear plant. Nuclear power stations are typically built by rivers and along coastlines so they can use water to cool down reactors.

 

Hungarian authorities are sinking the two barges to raise water levels so Paks, which provides the country with more than a third of its electricity, can continue to operate normally. The sinking began Saturday morning and Hungarian media are quoting the prime minister saying the water level at the plant has risen by 1 centimeter.

 

Magyar said on X that the current water level near Hungary's only nuclear energy facility is 122 cm lower than normal and it is projected to drop below 132 cm on Monday, which would force one of the plant’s two turbines to shut down.

 

On Wednesday, Magyar announced that they would be building a riverbed sill with 150,000 cubic meters of stone and was considering sinking the two 80-meter barges. A sill is an underwater dam meant to slow down the current and raise water levels. Hungary’s Defense Ministry has assigned 100 troops to work around the clock on the project, the prime minister said on X.

 

Nuclear energy facilities across Europe have been affected by this summer’s droughts and soaring temperatures. Romania shut down a nuclear power plant earlier this week due to the Danube’s water levels.

 

France — one of Europe’s biggest producers of nuclear power — has seen its fleet of nuclear power plants affected throughout the summer. Le Monde reported authorities had to shut down six of the country’s 57 nuclear reactors as yet another heat wave broiled much of the country. Earlier in the week, a climate change-fueled jellyfish invasion forced workers to bring parts of a different plant offline.

 

Magyar has also cast doubt on completing an expansion of the Paks plant by a Russian state-owned firm in a deal signed by Magyar’s predecessor, the Kremlin-friendly Viktor Orbàn, citing the water issue.
