Preventive Power Reduction of Unit 5 at Bulgaria's Kozloduy NPP

Bulgarian Energy Minister Iva Petrova stated in Sofia on August 21 that due to the persistently low water level of the Danube River, Unit 5 of the Kozloduy Nuclear Power Plant (Kozloduy NPP) has undergone a preventive reduction in power generation of approximately 120 MW, but the plant is currently not in a crisis situation. The unit has an installed capacity of slightly over 1,000 MW. Petrova said that the power reduction is a preventive measure within the plant's action plan for responding to the declining Danube water level, and the current situation is under control. She noted that if the water level continues to drop, Unit 5 may require further power reduction. At present, the plant has established an internal working group to continuously monitor hydrological changes. The situation is...

Bulgaria's Kozloduy NPP Reduces Power Output Due to Falling Danube River Levels

Bulgaria's Ministry of Energy stated that due to the sustained decline in the Danube River water level, Unit 5 of the Kozloduy NPP will reduce its power output by 120 megawatts starting August 21 to mitigate potential operational risks. The Ministry said in a statement that reducing reactor power is one of the measures to ensure the safe operation of the Kozloduy NPP, citing a sustained, abnormal, and rapid decline in the Danube River water level. The Danube River water level within Bulgaria is currently still on a downward trend. It is noted that this is the first time in the 52 years since the Kozloduy NPP was commissioned that its generating capacity has been reduced for such reasons. The plant uses Danube River water to cool the steam in the condensers of the conventional island, with water intake completed by dedicated pump stations located on the riverbank.
