Nuclearelectrica, the operator of Romania's sole nuclear power plant Cernavoda, said on Friday that one of the plant's two units has automatically disconnected from the grid due to an unidentified problem in the classical part of the plant.

"SN Nuclearelectrica SA announces that Cernavoda NPP Unit 2 was disconnected automatically from the National Power System during the evening of July 20th 2017, 17:40 hours, due to a transient occurring in the classical part of the power plant," Nuclearelectrica said in a press release.

A transient is the generic name of an event that causes a power plant to proceed from a normal state of operation to abnormal functioning.

Cernavoda experts are conducting a technical analysis to determine the nature of the transient, Nuclearelectrica said.

The systems of the power plant are operating in compliance with the design and the ongoing technical analysis has no impact on the nuclear safety of the reactor, the operating personnel, the population and the environment, Nuclearelectrica added.

Due to the fact that the nuclear reactor of Unit 2 is at power, the reconnection of the unit to the national power grid will be performed in several hours.
