Paks Nuclear Power Plant faces risks from Danube water levels

The Paks Nuclear Power Plant recently faced operational challenges due to extreme heatwaves and low water levels in the Danube River. During summer heatwaves, rising water temperatures required temporary exemptions from the 30 degree Celsius cooling water limit to maintain energy security. András Perger of Energiaklub noted that while these incidents are not yet systemic, the increasing frequency of high water temperatures is concerning.

In August, the plant narrowly avoided a potential shutdown caused by critically low water levels. The Ministry of Economy and Energy reported that the Danube's water level came within millimeters of a critical threshold before a slight rise allowed operations to continue. To mitigate future risks, preparations have begun for the construction of a riverbed sill between Paks and Dunaszentbenedek to help manage water levels.

Political discussions have also addressed the plant's operational status and energy exports. While some questioned the influence of external economic interests, the Ministry clarified that the risks were strictly environmental and that Hungary supported electricity imports during the period to maintain system balance rather than exporting to Ukraine.
