Danube Drought Forces Emergency Measures at Nuclear Plants

A severe drought across Central and Eastern Europe has pushed the Danube River to record-low water levels, creating a dangerous energy crisis. As the river continues to dry up, Romania and Hungary are struggling to keep their nuclear power plants running. These facilities rely on the Danube for cooling—a process where water is used to keep the reactor from getting too hot. Without enough water, the plants cannot operate safely.

In Romania, the government took an extreme step to protect the Cernavodǎ nuclear plant, which provides about one-fifth of the country's electricity. According to The Guardian, the Romanian navy used 180 kilograms of explosives to destroy a rocky area in the riverbed. This operation aimed to redirect water toward the channel that feeds the plant. Defense Minister Radu Miruțǎ stated that the mission was a success, noting that the cost of the explosion was much lower than the value of the electricity produced by the plant. However, officials warned that if this effort does not provide enough water, the facility might have to close completely by Thursday.

Hungary is facing a similar struggle at its Paks nuclear power station. This plant is vital to the country, as it normally generates nearly half of Hungary's electricity. Deutsche Welle reports that the plant is currently running at only a small fraction of its total capacity. While Prime Minister Péter Magyar initially warned of a total shutdown, he later shared more hopeful news, stating that the plant could continue to operate at a reduced level for a few more days. This reprieve is crucial, as it helps the country avoid a complete loss of power during a time of high energy demand.

To keep the power grid stable, both governments have asked for help from the public and private sectors. In Hungary, the government requested that citizens use less electricity, and they even stopped electric freight trains to save energy. Major companies are also playing a role; for example, the pharmaceutical company Richter announced it would cut its electricity use by more than 50% over the next three weeks. In Romania, caretaker Prime Minister Ilie Bolojan confirmed that major car manufacturers like Dacia and Ford have agreed to stop production until August 19 to help save power.

The situation is also affecting other energy sources. In Serbia, the Iron Gate hydroelectric plant—which uses the flow of water to create electricity—is operating at only 20% of its normal capacity. Prime Minister Djuro Macut held an emergency meeting on Monday to discuss the crisis. He urged residents to minimize the use of heavy energy consumers, such as air conditioners, to prevent the grid from failing.

Experts and officials are concerned because there is little sign of relief. According to Deutsche Welle, weather forecasts show no significant rainfall for the coming days or even weeks. Because the Danube flows through ten different countries, the low water levels are causing problems far beyond just power generation. The lack of water is also making it difficult for ships to transport goods, which could lead to further economic issues.

As the region faces this challenging period, leaders are emphasizing the need for cooperation. The Hungarian Prime Minister noted that coordinated steps and self-restraint from the public are essential to avoid more severe consequences. While the immediate danger of a total blackout has been pushed back for now, the long-term outlook remains uncertain. Both Romania and Hungary are currently relying on expensive power imports to fill the gap left by their reduced nuclear production. For now, the focus remains on managing the limited water supply and hoping that the current energy-saving measures will be enough to keep the lights on until conditions improve.
