SAN ONOFRE (CNS) - Southern California Edison announced Saturday it has informed the Nuclear Regulatory Commission that it has completed additional inspections of the San Onofre Nuclear Generating Station Unit 2 steam generators, based on Unit 3 findings.
On April 11, Southern California Edison identified wear in two of the 19,454 tubes in the Unit 2 generators that was similar to the type of wear that was previously seen in Unit 3. Southern California Edison conducted these inspections with technology specifically designed to identify this type of wear.
"Our number one priority is, and always has been, the health and safety of the public and our employees," said Southern California Edison Senior Vice President and Chief Nuclear Officer Pete Dietrich. "Our commitment remains the same; the utility will only bring the units on line when we and the NRC are satisfied that it is safe to do so."
Southern California Edison also provided a letter to the Nuclear Regulatory Commission today updating the ongoing Unit 2 steam generator tube inspections and to confirm the actions outlined in the commission's confirmatory action letter, which Southern California Edison received on March 27.
The letter outlines actions Southern California Edison must complete at the nuclear plant before seeking permission from the commission to restart Units 2 and 3.
Unit 3 of the plant south of San Clemente has been shut down since Jan. 31, when station operators detected a leak in one of its steam generator tubes.
Its two steam generators are undergoing extensive testing and inspections in order to fully assess their condition and the cause of the leak.
Unit 2 was taken down for planned maintenance Jan. 9.
Unit 1 was shut down in 1992 over fears that it could not withstand a major earthquake.
