Bulgaria’s nuclear power sector has regained a critical asset as the Kozloduy Nuclear Power Plant has successfully reconnected its 1,000 MW Unit 6 to the national electricity grid after a brief outage. This shutdown was necessitated by issues with protective equipment in the turbine’s non-nuclear section. Following the replacement of faulty components, engineers conducted thorough safety checks on the newly installed protective membranes in the turbine’s steam separator system, confirming that all systems are functioning correctly.
Unit 6 has faced multiple interruptions over recent months due to similar technical issues, with previous shutdowns recorded on December 15 and 21, as well as in February of this year. These recurring outages have raised concerns about the reliability of electricity generation from this unit.
The Bulgarian Energy Ministry estimates that approximately 200,000 MWh of electricity production was lost during these outages, translating into a financial impact of tens of millions of euros. The ministry noted that difficulties in sourcing original components from Russia contributed to these technical complications. In response to procurement challenges, alternative parts were installed to restore functionality.
This situation highlights significant risks associated with reliance on limited suppliers for critical technology. Caretaker Energy Minister Traycho Traykov emphasized the necessity for diversifying supply chains and finding dependable alternatives for essential equipment. As operations ramp up, the reactor is projected to achieve its full 1,000 MW output within the next two weeks, marking an important step toward stabilizing Bulgaria’s energy production capabilities.
