Bulgaria’s sole nuclear power plant Kozloduy announced that its 1,000 MW unit 5 was successfully reconnected to the national electricity grid on 09:33 on 28 May, following a month long maintenance downtime.

Unit 5 was taken offline on 24 April. The maintenance works included preventive technical maintenance and repairs of the equipment and systems, trials, specialized inspections and checks to secure the unit’s safe and reliable long-term operation. The reactor was refueled for the 29th fuel cycle.

Originally, NPP Kozloduy had six reactors, but four older 440 MW reactors were shut down in 2007 due to nuclear safety concern of the European Union. The plant currently operates two Soviet- built 1,000 MW reactors, unit 5 and unit 6 which were commissioned in 1987 and 1991 respectively.
