Southern California Edison Provides Responses to NRC Technical Questions  
ROSEMEAD, Calif., Feb. 1, 2013 — Southern California Edison (SCE) has begun 
sharing its technical responses to requests for additional information from the 
Nuclear Regulatory Commission (NRC) as part of the ongoing thorough review of 
SCE’s repair, corrective actions and restart proposal for Unit 2 of the San 
Onofre Nuclear Generating Station. 
“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 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 and at San Onofre is jointly owned by SCE (78.21 percent), San 
Diego Gas & Electric (20 percent) and the city of Riverside (1.79 percent).
