The Salem 2 nuclear power plant in southern New Jersey is shut down because of a problem with a reactor coolant pump.
Spokesman Jo Delmar tells Today's Sunbeam of Salem that the Salem 2 reactor went offline automatically at 6 p.m. Sunday. Delmar says an auxiliary pump automatically kicked in when the main pump shut down.
He says the cause is under investigation.
Salem 2 is one of three reactors operated at the Artificial Island generating site in Lower Alloways Creek Township on the Delaware River.
The Salem 1 and Hope Creek reactors continue to operate at full power. The three plants provide enough electricity to power 3 million homes.
