For the first time in its 52-year history, the Kozloduy NPP is preemptively limiting the operation of Unit 5 due to unprecedentedly low water levels in the Danube River.

Preventive measures at Kozloduy NPP

The Ministry of Energy has announced that, starting today, Kozloduy NPP is reducing the power output of Unit 5 by approximately 120 MW. The decision was prompted by the critical drop in the Danube River water level and forecasts for continued drought.

This is the first time in the plant's 52-year history that such a measure has been necessary due to extreme hydrological conditions.

Why is the restriction necessary?

The Ministry emphasizes that the safety of nuclear power facilities remains a priority. The plant's teams are working around the clock to optimize the operation of the pumps and cooling systems under the current difficult conditions.
