The sixth power unit of the Kozloduy NPP was unplugged from the country’s electrical grid on October 29 at 9 p.m., according to the plant’s managers. The generator’s cooling system, which is the non-nuclear portion of the device, is out of service due to a technical issue. The radiation situation has stayed the same. The nuclear power plant’s duty teams have taken all required steps to fix the problem and integrate the unit into the electricity system.
The sixth unit of the Kozloduy NPP had its yearly maintenance on the same day, as planned. At 12:52 p.m., the unit was linked to the national electrical grid after a Nuclear Regulatory Commission inspection.
The required equipment maintenance tasks were completed as part of the repair campaign, which got underway after the unit was shut down on September 24, 2022. A series of actions have been implemented to improve safety and guarantee the unit’s long-term performance. The unit six reactor has been reloaded with new nuclear fuel for the upcoming fuel campaign.
Currently, the Kozloduy NPP is in charge of two pressurised water reactors with a combined gross output of 2000 MWe and a net output of 1966 MW. VVER-1000 reactors are Units 5 and 6, built-in 1987 and 1991, respectively. As part of a plan to increase Unit 5’s capacity to 1,100 MWe by 2017, the unit’s lifespan was to be increased by 30 years.
The Kozloduy Nuclear plant is located 5 kilometres at 3 miles east of Kozloduy, a town on the Danube river close to the Romanian border and 180 kilometres (110 mi) north of Sofia. It is the only nuclear power station in the nation.
