Operators are working to restart the Salem 2 nuclear reactor in Lower Alloways Creek Township, NJ, after it shut down this weekend because of a valve problem on the non-nuclear side of the plant.

The reactor automatically shut down Sunday at 11:30 a.m. after a valve that controls water flowing through the steam generators did not respond to control room operators’ directions.

“The plant responded as designed with no major issues,” said Joe Delmar, a spokesman for the plant’s operator, PSEG Nuclear. “A repair plan has been developed for the valve and once repairs are completed we will take the appropriate steps to safely place the plant back online.”

The valve is on one of the feedwater pumps that supplies the water to the steam generators.

The water converts to steam which then spins the turbine at the plant which produces electricity.

An official from the Nuclear Regulatory Commission (NRC) said the shutdown was “uncomplicated.” NRC inspectors were monitoring the shutdown.

Salem 2 had just returned to service on Nov. 19 after a month-long scheduled refueling outage.

Delmar said there was no estimated time when the Salem 2 reactor would return to service.

Meanwhile, the other two units at PSEG Nuclear’s Artificial Island generating complex — Salem 1 and Hope Creek — remained operating at full power.
