Drought and Low Danube Levels Force Cutbacks at Hungarian, Romanian Nuclear Plants

Paks Nuclear Power Plant, Hungary

Where they agree

  • Both sources report that Hungary’s Paks nuclear plant faced a shutdown or severe power reduction due to drought conditions.
    Both connect the crisis to hot, dry weather and low water levels affecting the Danube region.
    The situation is framed as an unprecedented or unusual event for Hungary’s nuclear power generation.

Where they differ

  • DW provides extensive detail — specific capacity percentages, official quotes, and Romania’s parallel Cernavoda crisis — while France24 is represented only by a headline with no available article text.
    DW covers multiple countries (Hungary, Romania, Serbia), giving a regional picture, whereas France24’s headline focuses solely on Hungary.
    DW reports that Hungary managed to avoid a total shutdown by running Paks at reduced capacity, a nuance not evident from France24’s headline, which suggests a full shutdown occurred.

What’s happening on the Danube

Prolonged hot, dry weather has pushed the Danube River and other waterways in central and eastern Europe to record low levels, and the fallout has hit two of the region’s biggest nuclear power stations. In Hungary, the Paks nuclear plant — which normally supplies almost half the country’s electricity and about a third of its total consumption — was running at just over 10% capacity on Monday because there wasn’t enough river water to cool it. In Romania, the Cernavoda plant, which draws all its cooling water from the Danube and typically generates roughly one-fifth of the country’s power, came under similar strain.

How each country is responding

Hungarian Prime Minister Peter Magyar said the previously announced possibility of a full shutdown of Paks could be avoided. He credited voluntary conservation by households and industry, saying consumption on Monday was running well below planned levels. Hungary had asked industrial users to cut back and had stopped electric-powered freight trains to ease the strain on the grid. Magyar said water management forecasts for the coming days looked “slightly more optimistic” and that the plant’s last operating turbine was still running, with an update expected from grid operator MAVIR’s control room.

Romania took a more drastic, physical approach: the military detonated a rocky outcrop that had been exposed in the riverbed of a Danube branch, about 50 kilometers upstream from Cernavoda, to try to redirect and raise water levels near the plant. Defense Minister Radu Miruta called the operation a success and said the army had been waiting decades for the chance to blow up the rocks. The debris was to be moved to a strategic point and sunk to help boost flow. Miruta warned that if this partial diversion didn’t work, Cernavoda would likely have to shut down completely by Thursday. Caretaker Prime Minister Ilie Bolojan said carmakers Dacia and Ford had agreed, after a crisis meeting with energy-intensive industries, to suspend Romanian production until August 19, with other companies expected to follow suit.

Serbia was also affected, with hydroelectric power output significantly reduced by the dry conditions, though details on Serbia’s response were not elaborated.

Why cooling water matters this much

Nuclear plants like Paks and Cernavoda rely on river water to cool their reactors, and both discharge warmed water back into the Danube. When river levels drop and temperatures rise, plants either can’t draw enough water or risk returning water that’s too hot for the environment, forcing operators to throttle output or shut down. With continued hot, dry weather forecast through the week and no clear sign of relief, the situation in both countries remained precarious as of the reporting.

How the coverage compares

DW’s account, drawing on statements from Hungarian and Romanian officials, gives a detailed, ground-level picture of the crisis: specific capacity figures for Paks, the mechanics and timeline of Romania’s demolition operation, direct quotes from Magyar and Miruta, and concrete industrial impacts like the Dacia and Ford production pause. It also folds in Serbia’s hydropower troubles, giving the story a wider regional frame. France24’s item, by contrast, is represented here only by its headline, which frames the story narrowly around Hungary’s decision to shut down its nuclear plant amid drought and heat — without underlying article text available for further detail, so it’s unclear how it characterizes the scale of the shutdown, Romania’s parallel crisis, or the eventual partial recovery Magyar described.

The bigger picture

The episode illustrates a growing vulnerability for European countries that lean on river-cooled nuclear power: extreme heat and drought, which climate scientists link to a warming climate, can constrain the very infrastructure meant to keep the lights on. Hungary’s Paks and Romania’s Cernavoda are both significant pillars of their national grids, and disruptions ripple quickly into industry — as shown by Romania’s automakers halting output — and into everyday life through calls for household conservation and cuts to rail freight. The improvised measures taken here, from Hungary’s public appeals for restraint to Romania’s military demolition of riverbed rock, point to how directly climate-driven water scarcity can now intersect with energy security in the region.
