UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 October 19, 2015 Mr. Thomas J. Palmisano Vice President and Chief Nuclear Officer Southern California Edison Company San Onofre Nuclear Generating Station P.O. Box 128 San Clemente, CA 92674-0128

SUBJECT:

SAN ONOFRE NUCLEAR GENERATING STATION, UNITS 2 AND 3 -

ACCEPTANCE REVIEW OF THE LICENSE AMENDMENT REQUEST TO MAKE CHANGES TO SPECIFIC REGULATORY GUIDE COMMITMENTS RELATED TO THE IMPLEMENTATION OF "COLD AND DARK" STATUS (TAC NOS. L53073 AND L53074)

Dear Mr. Palmisano:

By letter dated August 20, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15236A018), Southern California Edison (SCE) submitted a proposed amendment to the San Onofre Nuclear Generating Station, Units 2 and 3 (SONGS)

Updated Final Safety Analysis Report (UFSAR) for review and approval by the U.S. Nuclear Regulatory Commission (NRC). The proposed amendment would revise Appendix 3A of the UFSAR to more fully reflect the permanently shutdown status of SONGS. The revision would include a limited set of exceptions and clarifications to referenced Regulatory Guides to reflect the significantly reduced decay heat loads in the SONGS Units 2 and 3 Spent Fuel Pools and to support corresponding design basis changes and modifications that will allow for implementation of the "cold and dark" strategy outlined in the SONGS Post-Shutdown Decommissioning Activities Report (PSDAR).

The purpose of this letter is to provide the results of the NRC staff's acceptance review of the submittal. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of this request in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staff's ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.

T. Palmisano If you have any questions, please contact me at (301) 415-3178 or via e-mail at marlayna.vaaler@nrc.gov.
