“The unplanned outages represent controlled shutdowns of the nuclear power plant in order to perform precise remediation works on certain equipment, in addition to the annual corrective maintenance program within the planned outages,” the company said in a statement.

The same reactor was shut down two times before this year, for repair or maintenance works.

Nuclearelectrica operates Romania’s sole nuclear power plant in Cernavoda, whose two 700-megawatt reactors cover around 18% of the country’s electricity consumption.
