SCE Considers License Amendment for San Onofre Nuclear Plant

  SCE Considers License Amendment for San Onofre Nuclear Plant

Business Wire

ROSEMEAD, Calif. -- March 22, 2013

Southern California Edison (SCE) is considering voluntarily submitting a
license amendment request to the Nuclear Regulatory Commission (NRC) to
support the restart of Unit 2 of the San Onofre Nuclear Generating Station.
The amendment is consistent with SCE’s plan to operate the unit’s steam
generators at 70 percent power as a conservative safety measure.

SCE is requesting a meeting with the NRC to discuss the possible amendment.
This meeting, which would be open to the public, would provide an opportunity
for SCE to discuss with the NRC the scope and content of a potential amendment
to ensure it meets regulatory requirements. The meeting will also help SCE
evaluate the nature and timeliness of the NRC process for review and approval
of the amendment. Separately, SCE representatives have informed the Atomic
Safety Licensing Board, the independent, adjudicatory arm of the NRC, of the
company’s consideration of submitting a license amendment.

SCE would like to restart Unit 2 by the summer to meet peak customer demand
for electricity. The San Onofre nuclear plant is the largest source of
baseload generation and voltage support in the region and is a critical asset
for reliability and in meeting California’s clean energy goals.

Last week, SCE submitted a detailed operational assessment requested by the
NRC that supports safe operation of Unit 2 at 100 percent power for 11 months
to answer a request from the NRC related to the plant’s technical
specifications. Approval of that assessment would eliminate the need for the
license amendment. However, because the NRC may take substantial time to
review this operational assessment, SCE is simultaneously considering the
license amendment.

“We want to do every responsible thing we can do to get Unit 2 up and running
safely before the summer heat hits our region,” said Ron Litzinger, SCE
president. “While the NRC continues to review the technical materials we’ve
submitted, we’re considering a request for a license amendment so that we can
pursue the best path to safe restart while avoiding unnecessary delays.”

If SCE pursues the amendment, it will submit a “No Significant Hazards
Consideration” analysis demonstrating that the license amendment does not
involve any significant safety risks. Regardless of whether an amendment or
SCE’s 100 percent power operational assessment is approved, SCE will only
operate Unit 2 at 70 percent power for an initial period of five months,
following which the unit will be shut down for steam generator tube

NRC approval is required before SCE can restart Unit 2. The repair, corrective
action and restart plan for Unit 2, along with additional technical
information to address questions from the NRC, are available to the public at
