ROSEMEAD, Calif., Jan. 31, 2012 – Southern California Edison (SCE), operator of the San Onofre Nuclear Generating Station, has begun a precautionary shutdown of Unit 3 because sensors installed for this purpose detected a possible leak in one of the unit’s steam generator tubes.
The potential leak poses no imminent danger to the public or plant workers. There has been no release to the atmosphere. San Onofre personnel will evaluate the cause of the leak and the steps required to repair it and resume operations.
Unit 2 is currently offline for a planned maintenance, refueling and technology upgrade outage. Southern California Edison has ample reserve power to meet customer needs while Unit 3 is offline.
The Nuclear Regulatory Commission was immediately informed of this development.
