A South Jersey nuclear reactor remained offline Monday after a problem on the non-nuclear side of the plant caused an automatic shutdown.
The Salem 2 reactor turned off around 11:30 a.m. Sunday after a valve that controls water flowing through the steam generators didn't respond properly.
The valve is on one of the feedwater pumps that supplies water to the steam generators. The water is converted to steam, which spins the turbine at the plant which produces electricity.
Plant officials say the shutdown occurred without incident, but it's not clear when the reactor will return to service.
Salem 2 is one of three reactors operated by PSEG Nuclear at its Artificial Island complex in Lower Alloways Creek Township. The other plants were not affected by the valve problem.
