Southern California Edison Provides Responses to NRC Technical Questions
“We are very confident in our safe restart plan for Unit 2,” said Pete Dietrich, senior vice president and chief nuclear officer “This technical question and answer process is an important part of safety-based technical solutions in the nuclear industry, and it strengthens our ability to communicate the safety principles and proven industry operating experience that the plan was built on.”
The responses will be posted at www.SONGScommunity.com as they are available.
SCE’s restart analyses includes evaluations from independent international experts who completed more than 170,000 inspections to understand the tube wear issues and confirm the effectiveness of corrective actions. SCE’s proposal includes preventive tube plugging and operating Unit 2 at 70 percent power for a five-month period.
San Onofre is the largest source of baseload generation and voltage support in the region and is a critical asset in meeting California’s clean energy needs. Both units at San Onofre are currently safely shut down. Unit 2 remains shut down since it was taken out of service Jan. 9, 2012, for a planned outage. Unit 3 was safely taken offline Jan. 31, 2012, after station operators detected a leak in a steam generator tube.
More information is available at www.edison.com/SONGSupdate and at www.SONGScommunity.com. San Onofre is jointly owned by SCE (78.21 percent), San Diego Gas & Electric (20 percent) and the city of Riverside (1.79 percent).
