Hungary to raise Danube River levels to secure nuclear power plant
BUDAPEST, Hungary — Authorities in Hungary will begin taking steps to raise the level of the Danube River this week in order to ensure the country’s only nuclear power plant can continue operating, Prime Minister Péter Magyar said on Wednesday, reports BritPanorama.
Persistent drought and successive extreme heat waves in recent months have deprived one of Europe’s largest rivers of water, bringing Danube levels to record lows and pushing the Paks nuclear power plant to the brink of shutting down for the first time in its 44-year history.
The Soviet-built plant, which uses water from the Danube to cool its four reactors, is currently operating at little more than 10% of its 2,000 megawatt capacity due to low water levels. It supplies Hungary with around a third of its electricity.
In a video posted to Facebook on Wednesday, Magyar announced that authorities would begin building a bed sill — a low concrete or stone structure built into the riverbed to slow the current and raise upstream water levels — on Thursday on a section of the Danube just upriver from the plant.
Delivery of approximately 145,000 cubic meters of rocks used in its construction would start on Wednesday evening, with the potential to raise the level of the Danube by up to a meter (3 feet).
Meanwhile, two 80-meter (262-foot) barges will be transported to the site near Paks and may be sunk to raise the Danube further by up to 20 centimeters (8 inches) at the plant’s cooling pumps. A decision on whether to sink them will be made on Friday, Magyar said.
“We can no longer consider this extraordinary situation as a one-time natural extreme,” he indicated, stressing the necessity for quick action to prevent a full shutdown of the Paks plant.
Magyar characterized the construction of the bed sill as a “long-term” solution to ensure that water levels never drop below the threshold at which the reactors at Paks must be powered down.
He added that following a recent temporary rise in water levels, they are expected to fall again in the coming days, which, without external intervention, could lead to the complete shutdown of the Paks plant.
“The Danube has given us days, not months,” he said.
Similar measures were adopted in Romania last week when authorities sank four barges laden with rock into the Danube to redirect water downstream toward the Cernavoda nuclear plant, which had already shut down one of its two reactors due to low water levels.
On Wednesday, Magyar stated that the Paks plant operating at its current output is costing Hungary’s economy up to 50 billion forints ($158 million) per month. In contrast, he noted that the planned interventions on the Danube will cost around 6 billion forints ($19 million).
