NRC TO MEET WITH SOUTHERN CALIFORNIA EDISON CO. OFFICIALS TO 

DISCUSS SAN ONOFRE NUCLEAR GENERATING STATION STEAM GENERATOR 

ISSUES

The Nuclear Regulatory Commission has rescheduled a meeting with representatives of 

Southern California Edison Co. (SCE) for Nov. 30 to address the company’s response to the 

NRC’s Confirmatory Action Letter concerning actions required to be taken to address steam 

generator tube degradation at the San Onofre Nuclear Generating Station. The plant, operated by 

SCE, is located in San Clemente, Calif.

The meeting will be held between 6 and 9 p.m. (PST) at the Hills Hotel, 25205 La Paz 

Road in Laguna Hills, Calif.

NRC staff will meet with SCE officials to discuss the company’s response to the NRC 

Confirmatory Action Letter of March 27, 2012, concerning actions required to be taken by the 

company to address steam generator tube degradation at San Onofre. The company’s response to 

the Confirmatory Action Letter is available at:

http://pbadupws.nrc.gov/docs/ML1228/ML122850320.html .

A leak in a Unit 3 steam generator tube on Jan. 31 led to the shutdown of that unit. The 

other reactor, Unit 2, was off-line for maintenance and refueling at the time. Subsequent 

inspections of the nearly new steam generators in both units found unexpected wear. Both units 

remain safely shut down and will not be permitted to restart until NRC has reasonable assurance 

they can be operated safely. 

The meeting will include a technical presentation by SCE on the basis, methodology, and 

conclusions of their efforts to identify the causes of the unexpected steam generator tube wear, 

the corrective actions taken to address those causes, and the basis for continued safe operation of 

Unit 2. The presentation and NRC dialogue is expected to require the majority of the meeting 

time. The public is invited to observe the meeting and will have an opportunity to communicate 

with the NRC staff after the business portion of the meeting, before it is adjourned.
