  Virtual Tour of San Onofre Nuclear Plant Now Online

Business Wire

ROSEMEAD, Calif. -- November 27, 2012

Online visitors to SONGScommunity.com can now take a virtual tour of the San
Onofre Nuclear Generating Station, allowing them to explore inside the 2,200
megawatt nuclear power plant located near San Clemente, Calif.

Safety is the main focus during the online experience and key features
including containment domes, the seawall and emergency diesel generators are
explained through video and audio. The tour is available in English and
Spanish.

“A nuclear plant doesn’t have many tours open to the public for safety and
security reasons,” said Pete Dietrich, senior vice president and chief nuclear
officer. “But with this virtual tour, our community members, our customers and
anyone around the world can come inside the plant and understand what the
facility does and how it works.”

The virtual tour is part of ongoing efforts to inform and educate the public
on the plant overall and specifically on the technical repair, corrective
actions and proposal to safely restart and operate Unit 2. Engineers and
community liaisons are also conducting open houses in several communities in
the region and are available to speak to groups upon request.

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 of the plant are currently safely shut down. Unit 2 was taken out
of service Jan. 9 for a planned outage. Unit 3 was safely taken offline Jan.
31 after station operators detected a leak in a steam generator tube. Southern
California Edison (SCE) submitted its response to the Nuclear Regulatory
Commission’s (NRC) Confirmatory Action Letter on Oct. 4, along with its
restart plan for Unit 2. The unit will not be restarted until all plans have
been approved by the NRC.

The San Onofre plant is jointly owned by SCE (78.21 percent), San Diego Gas &
Electric (20 percent) and the city of Riverside (1.79 percent).
