NRC TO DISCUSS 2010 PERFORMANCE ASSESSMENT FOR
SAN ONOFRE NUCLEAR GENERATING STATION
The Nuclear Regulatory Commission staff will meet in San Juan Capistrano, Calif., on
April 28, with representatives of Southern California Edison Co. to discuss the agency=s 2010
assessment of safety performance at the San Onofre Nuclear Generating Station.
The meeting, which will be open to the public, will begin at 6:00 p.m. at the Capistrano
Unified School District Board Room, 33122 Valle Road, San Juan Capistrano.
Following the performance assessment, the NRC staff will be available to answer
questions from the public concerning San Onofre, as well as the NRC=s role in ensuring safe
plant operation.
AThe NRC continually reviews the performance of San Onofre and the nation=s other
commercial nuclear power facilities,@ NRC Region IV Administrator Elmo Collins said. This
meeting will provide an opportunity for a discussion of our annual assessment of safety
performance with the company and with local officials and residents who live near the plant.@
A letter sent from the NRC Region IV office to plant officials addresses the performance
of the plant during 2010 and will serve as the basis for the meeting discussion. It is available on
the NRC web site at http://www.nrc.gov/NRR/OVERSIGHT/ASSESS/LETTERS/sano_2010q4.pdf.
San Onofre operated safely in 2010. The licensee addressed longstanding concerns in the
area of problem identification and resolution, but has not been fully successful in addressing
several longstanding human performance issues. The NRC will conduct additional focused
inspections in the human performance area, and also in the safety conscious work environment
area to verify that corrective actions are effective and sustainable.
