Record low water levels in the Danube River, caused by prolonged drought, are threatening the operation of nuclear power plants in Romania and Hungary. Cooling systems at these plants rely on water from the Danube, and insufficient levels could force reduced output or even shutdowns. This poses risks of power shortages across central and eastern Europe, potentially impacting various industries. River transport is also severely disrupted, hindering the movement of goods like coal, grain and steel. Authorities are monitoring the situation closely and exploring potential mitigation measures, including utilizing alternative water sources or adjusting energy production. The ongoing heatwave and lack of rainfall are exacerbating the problem, with no immediate relief in sight. This situation highlights the growing vulnerability of critical infrastructure to climate change impacts in the region.
