Record-Low Danube Puts Romania’s Cernavoda Nuclear Plant and Europe’s Energy Security Under Strain
Record-low water levels on the Danube have forced Romania to shut one of two reactors at its Cernavoda nuclear plant and raised concerns about cooling the remaining unit. As engineers dredge the river and redirect flows with rock-filled barges, the episode shows how climate stress can turn vital power infrastructure into a front line of risk for households and grids well beyond Romania.
When river levels become a national security variable, the cost of climate stress is no longer abstract. Romania’s Cernavoda nuclear plant, a cornerstone of the country’s electricity system, has been forced to take one of its two reactors offline after record-low water on the Danube threatened its cooling capacity. Authorities now face a race against the forecast, which suggests the river could keep falling through at least 16 August. Operators shut down the affected reactor as a precautionary measure, citing insufficient water levels to safely sustain normal cooling operations. The remaining reactor continues to run, but with heightened concern over its own cooling needs as the Danube, which supplies water…
