Danube Record Lows Force Hungary Nuclear Shutdown Amid Heatwave

Extreme heat and record-low Danube levels have closed Hungary's nuclear plant and triggered red alerts across Italy.
Record-low water levels in the Danube River have forced the shutdown of Hungary’s only nuclear power plant, MVM Paks. The plant, which relies on the river for cooling, can no longer operate safely as water levels have dropped below critical thresholds due to a prolonged heatwave and lack of rainfall. The shutdown is expected to put significant pressure on Hungary's power grid.
The environmental crisis is not limited to Hungary; Romania, Bulgaria, and Serbia are also reporting historically low levels for the Danube. The lack of water is disrupting shipping lanes and agricultural irrigation across Central and Eastern Europe. Climate experts note that the frequency of these extreme low-flow events is increasing, posing a long-term threat to energy infrastructure that depends on river water.
In a related weather event, Italy has placed nearly all major cities, including Rome, Milan, and Naples, on red alert for extreme heat. The heatwave is expected to intensify through Monday, with temperatures reaching dangerous levels. Public health officials are urging citizens to stay indoors as the energy sector struggles to keep up with the soaring demand for air conditioning.
