Southern California Edison (SCE) installed monitoring instruments at Unit 3 at the 2,200 MW San Onofre Nuclear Generating Station in California to find a leak.
Instruments detected a leak in the steam generator tube Jan. 31 and workers safely shut down the plant and isolated the component containing the leaking tube. Unit 3 is currently cooling down and workers are reducing pressure in the plant to stop the leak.
Unit 2 was taken offline Jan. 9 for a planned refueling and maintenance outage. SCE said the company has enough reserve power to meet demand.
