Unit six at Bulgaria’s Kozloduy nuclear power station was taken offline again for a second time in three days on October 30, only five days after it was reconnected to the power grid following scheduled maintenance.
The decision was prompted by a loss of power in the reactor power control systems, the power plant said in a statement. The Nuclear Regulatory Agency has been notified about the case, the statement said.
On October 28, unit six at Kozloduy was taken offline because of a fault in the drainage pipeline of the unit’s turbo generator. The fault was fixed and the unit was reconnected to the power grid a day later.
After shutting down four 440MW units in 2005 and 2006 as a pre-condition to European Union accession, Kozloduy has two 1000MW Soviet-built reactors in operation.
