It said Unit 1 will be shut down in a controlled manner to remedy an issue on the classic/secondary technological circuit.

The controlled shutdown of Cernavoda’s Unit 1 is performed according to the procedures applicable in case of such events and is necessary in order to allow staff to perform the remediation works under safety conditions given the fact that the working fluid (demineralized water) is at high temperature and pressure.

The failure occurred at the classic technological circuit of Unit 1 and the related remediation works do not have any adverse impact on the nuclear safety, the environment, the personnel or the population, Nuclearelectrica said.
