Paks output slashed as Danube levels hit records

Hungary’s only nuclear power plant, the Paks facility, has cut electricity production significantly as falling water levels on the Danube River restrict its ability to cool reactors. The plant, which has a combined capacity of 2,000 megawatts, was recently generating about 965 megawatts of power, well below its normal output.

Data from national authorities also showed that at one stage the plant’s production fell to less than a quarter of its rated capacity. These figures reflect a rapid tightening of operating conditions as the river feeding the plant’s cooling systems recedes to record lows.

Cooling constraints force progressive cutbacks

Paks uses water drawn from the Danube to cool its reactors. Recent readings show the river has dropped so low that the plant’s intake systems face increasing difficulty reaching sufficient water for safe cooling.

The unusually low river level has driven a sequence of output reductions aimed at maintaining safety limits. Officials have indicated that the plant’s cooling constraints, rather than technical faults at the reactors themselves, are the driver of the curtailed production.

Government warns of looming energy crisis

Prime Minister Péter Magyar has said that Paks will likely be fully powered down by Tuesday or Wednesday. He also stated that once offline, the plant may not return to service for several weeks, depending on how long the Danube remains at its current low level.

Magyar warned that Hungary’s energy supply could become critical as a result of the loss of output from Paks, which normally provides a large share of the country’s electricity. He has urged households and businesses to reduce their electricity consumption to help manage the strain on the grid.

Contingency measures and imports planned

To mitigate the impact of reduced nuclear output, the government is preparing contingency measures and plans to increase electricity imports. These steps are intended to stabilize supply during the period when Paks is operating at limited capacity or fully offline.

The combination of record-low Danube levels, reduced nuclear generation and elevated seasonal demand has concentrated attention on short-term security of supply. Authorities are monitoring river conditions and plant status while emphasizing that shutdown procedures can be carried out safely, without risk to the public or the environment.

Key Takeaways

01Paks’ reduced output is directly linked to cooling limits from low Danube levels, rather than internal reactor faults.
02A full shutdown within days, followed by a possible multiweek outage, creates a near-term supply risk for Hungary.
03Government appeals for demand reduction and plans for higher imports underscore reliance on a single major nuclear source.
