The company informed that a problem related to cooling system electric generator had led to the temporary closure of the reactor on 9 January.

Nuclearelectrica general director Dumitru Dean was quoted by RL news portal as saying that nothing serious has happened at the nuclear power station.

Automatic shut down of the nuclear reactor had no impact on nuclear security, population and environment. Meanwhile, output of electricity production came down.

The Cernavoda NPP is the only nuclear generating station in Romania, and it is comprised of two units with Canadian-made CANDU heavy water reactors.

Each reactor has 700MW capacity – together they produce about 18% of electricity consumed in Romania.
