By letter dated October 3, 2012, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML122850320) Southern California Edison (SCE) submitted its response to the NRC Confirmatory Action Letter (CAL) dated March 27, 2012, for San Onofre Nuclear Generating Station (SONGS), Unit 2. In support of that response, SCE submitted proprietary versions of several reports by letter dated November 28, 2012 (ADAMS Accession No. ML12348A287).
The CAL specifies SCEs commitments to provide to NRC the results of your assessment of the replacement steam generator tube wear identified at SONGS, the actions taken to prevent loss of tube integrity in Unit 2, and the basis for SCEs conclusion that there is reasonable assurance that the unit can be operated safely. The CAL further stipulates that it will remain in effect until the NRC has reviewed SCEs response to the actions specified therein, including responses to staffs questions and the results of your evaluations; and the NRC staff communicates to SCE in writing that it has concluded that Unit 2 can be operated without undue risk to public health and safety, and the environment.
The NRC staff is continuing its detailed review of the information provided by SCE in support of your conclusion that SG tube integrity will be maintained, and that there is reasonable assurance, as required by NRC regulations, that Unit 2 will operate safely. To complete our review, the staff has determined that additional information is needed regarding the operational assessments discussed in your CAL response.
The staffs latest request for additional information (RAI) is attached. Please note that although the NRC staff has determined that the attached questions are not proprietary, many of the questions refer to information that SCE has requested be withheld in its letter dated November 28, 2012. The NRC staff intends to make this RAI publicly available in advance of our February 27, 2013, meeting with you here at NRC headquarters. If SCE believes that any information in this RAI is proprietary, you are requested to specify that information to me no later than 1:00 PM EST on February 25, 2013. Following any discussions to clarify this RAI, we will formally transmit the final version to you by letter.
The NRC staff may develop additional questions, which we will transmit to SCE as they
become available. Please let me know if you have any questions.

Draft Request for Additional Information on SCE"s Response to NRC"s Confirmatory Action Letter for San Onofre Nuclear Generating Station Unit 2 RAIs 53-67 (ME9727)

Date: Thursday, February 21, 2013 5:07:00 PM Attachments: RAIs 53 to 67.docx February 21, 2013 Mr. Ryan Treadway Manager, Nuclear Regulatory Affairs San Onofre Nuclear Generating Station Southern California Edison Company Ryan:

By letter dated October 3, 2012, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML122850320) Southern California Edison (SCE) submitted its response to the NRC Confirmatory Action Letter (CAL) dated March 27, 2012, for San Onofre Nuclear Generating Station (SONGS), Unit 2. In support of that response, SCE submitted proprietary versions of several reports by letter dated November 28, 2012 (ADAMS Accession No. ML12348A287).

The CAL specifies SCEs commitments to provide to NRC the results of your assessment of the replacement steam generator tube wear identified at SONGS, the actions taken to prevent loss of tube integrity in Unit 2, and the basis for SCEs conclusion that there is reasonable assurance that the unit can be operated safely. The CAL further stipulates that it will remain in effect until the NRC has reviewed SCEs response to the actions specified therein, including responses to staffs questions and the results of your evaluations; and the NRC staff communicates to SCE in writing that it has concluded that Unit 2 can be operated without undue risk to public health and safety, and the environment.

The NRC staff is continuing its detailed review of the information provided by SCE in support of your conclusion that SG tube integrity will be maintained, and that there is reasonable assurance, as required by NRC regulations, that Unit 2 will operate safely. To complete our review, the staff has determined that additional information is needed regarding the operational assessments discussed in your CAL response.

The staffs latest request for additional information (RAI) is attached. Please note that although the NRC staff has determined that the attached questions are not proprietary, many of the questions refer to information that SCE has requested be withheld in its letter dated November 28, 2012. The NRC staff intends to make this RAI publicly available in advance of our February 27, 2013, meeting with you here at NRC headquarters. If SCE believes that any information in this RAI is proprietary, you are requested to specify that information to me no later than 1:00 PM EST on February 25, 2013. Following any discussions to clarify this RAI, we will formally transmit the final version to you by letter.

The NRC staff may develop additional questions, which we will transmit to SCE as they

become available. Please let me know if you have any questions.

Sincerely, Randy Hall, Senior Project Manager San Onofre Special Projects Branch Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation USNRC (301) 415-4032 Randy.Hall@nrc.gov
