  SCE Submits Draft License Amendment for Nuclear Plant Unit 2 Restart

ROSEMEAD, Calif. -- April 1, 2013

Southern California Edison (SCE) has voluntarily submitted a draft license
amendment request to the Nuclear Regulatory Commission (NRC) for discussion.
The draft is designed to support safely restarting Unit 2 of the San Onofre
Nuclear Generating Station to address customer electricity demand and grid
reliability concerns during the upcoming summer months. SCE is considering
submitting a final amendment request after discussing it with the NRC staff at
a public meeting Wednesday in Rockville, Maryland.

The draft license amendment request, if finalized and submitted for NRC
approval, would support SCE’s plan to operate Unit 2 at 70 percent power for
five months. Operating at 70 percent power prevents conditions that caused the
tube-to-tube wear in Unit 3 that resulted in the nuclear plant being shut down
since January 2012. SCE and three independent companies with expertise in
nuclear generation have confirmed it is safe to operate the Unit 2 steam
generators. The NRC has been evaluating these analyses, which are based on
exhaustive testing and inspections, since October 2012.

“Since last fall, SCE has provided the public and the NRC with detailed
analyses from global experts that support safe restart of Unit 2,” said Ron
Litzinger, SCE president. “We are considering the proposed voluntary amendment
as the best path to get Unit 2 safely up and running before the hottest months
of the year hit our region.”

SCE would be asking the NRC to act on the amendment before the end of May to
facilitate timely restart of Unit 2 to meet peak summer electricity demand.
Following the initial five-month operating period, SCE would shut down Unit 2
for steam generator tube inspections. Based on inspection data, Unit 2 would
resume operation at 70 percent power for an appropriate operating period
during the remainder of the 18-24 month fuel cycle while SCE updates its
analysis to determine the appropriate long-term power level.

The San Onofre nuclear plant 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. According to testimony filed by SCE for its General Rate
Case and as part of a report prepared in 2010 by IHS Global Insight, operating
the nuclear plant directly generates economic activity worth on average $2.2
billion per year. The impact grows to $3.3 billion per year if secondary
economic effects are considered, which include the supply chain purchases of
businesses supported by the nuclear plant and spending by those employed by
the plant.

Both units at the San Onofre nuclear plant 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.

San Diego Gas & Electric (20 percent) and the city of Riverside (1.79
percent). Follow us on Twitter (www.twitter.com/SCE) and like us on Facebook
