One of two reactors at Bulgaria's nuclear plant at Kozloduy has been plugged back into the electricity grid after being shut down for maintenance last week, the plant's operators said Wednesday.

During the planned repair work on the 1,000-megawatt reactor, a faulty valve regulating steam into the reactor turbine was replaced, the plant's operators said in a statement.

Three imilar valves, which had been scheduled to be replaced later this year, were changed ahead of schedule.

The other 1,000-megawatt reactor in operation at Kozloduy was working at maximum capacity during the repairs, the statement said.

Four 440-megawatt units at Kozloduy were closed in 2002 and 2006 as a condition for joining the European Union in 2007. The old Soviet-built reactors were deemed unsafe.
