San Onofre nuclear power plant shutting down
June 7, 2013
Southern California Edison announced Friday it will retire the Unit 2 and Unit 3 reactors and lay off approximately 1,000 employees.
San Onofre has not generated any electricity since January 31, 2012, when officials discovered an 82 gallon per day fluid leakage in the Unit 3 replacement generator. Unit 2 was undergoing a refueling outage at the time of the shutdown. The third reactor, Unit 1, has been decommissioned since 1992.
Upon shutdown, San Onofre officials discovered higher than expected tube wear in the replacement generators of both reactors. The Mitsubishi Heavy Industries report determined that tube wear from contact with other tubes, anti-vibration bars and retainer bars in the Unit 3 replacement steam generator caused the leakage.
Ted Craver, Chairman and CEO of Edison International, parent company of SCE, said the uncertainty about when and if the plant might return to service was not good for its customers and investors.
Southern California Edison also announced plans to pursue recovery of damages from Mitsubishi Heavy Industries, the supplier of the replacement steam generators, as well as recovery of amounts under applicable insurance policies.
