Bulgarian nuclear power plant Kozloduy-upgrade contract with Rusatom Service

, SEE Energy News

A 14.5 million euros contract was signed between Bulgarian sole nuclear power plant Kozloduy and Russian Rusatom Service, part of state-owned nuclear energy company Rosatom.

This contract is for upgrade of the neutron flux control systems of both units.

The statement from the company said that The upgrade of the neutron flux control systems is related to NPP Kozloduy’s project for increasing the operating capacity of its two units to 104 %. Rusatom Service was the sole bidder at the tender for the upgrade.

Last October, operational life of NPP Kozloduy’s unit 6 was extended by additional 10 years. In 2017, unit 5 received 10-year operational license extension, which will expire in 2027. In 2018, Bulgarian Nuclear Regulatory Agency (BNRA) has granted approval for continuous operation of NPP Kozloduy unit 6 at increased thermal capacity of 104 %.

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.
