Hydropower units and a group at thermal plant Turceni have been activated to compensate for the Cernavoda reactor’s downtime, the sources said.

Nuclearelectrica issued a statement confirming that the reactor was shut down at 7:42 a.m., after vibrations were detected in the turbine. “All of the plant’s systems worked as designed; the reactor’s power was kept at 60%. (…) This event did not affect the safety of the plant’s staff, the public or the environment,” the statement said.

The same reactor had been restarted last week after a scheduled overhaul that took more than 30 days.

The Cernavoda plant, with its two units, covers around 18% of the national energy production.
