Based on the Nuclear Regulatory Commission (NRC) staff's review of SCE's license amendment request submittals, a response to the attached draft request for additional information (RAI) is required to facilitate completion of the staff's technical review. I am sending you this preliminary copy to give you an opportunity to ask clarifying questions if the request is not clear. This RAI will be made publicly available following your review.

Please let me know if SCE would like to have a conference call with the NRC staff to clarify this request. Also, let's discuss the proposed timing for SCE's response. Tom Wengert Senior Project Manager U.S. Nuclear Regulatory Commission NRR/DORL/LPL4-2 (301) 415-4037

DRAFT REQUEST FOR ADDITIONAL INFORMATION DEFUELED TECHNICAL SPECIFICATION LICENSE AMENDMENT REQUEST SAN ONOFRE NUCLEAR GENERATING STATION, UNITS 2 AND 3 SOUTHERN CALIFORNIA EDISON DOCKET NOS. 50-361 AND 50-362 TAC NOS. MF3774 AND MF3775 By letter dated March 21, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14085A141), as supplemented by letter dated October 1, 2014 (ADAMS Accession No. ML14280A264), Southern California Edison requested an amendment to the facility operating licenses. The requested amendment would revise the operating licenses and associated Technical Specifications (TSs) to reflect the permanent cessation of reactor operation and the permanently defueled condition of the reactor vessels at San Onofre Nuclear Generating Station (SONGS), Units 2 and 3. The proposed amendment would eliminate most of the previous operating TSs because these TSs are only applicable in operating modes or conditions where fuel is emplaced within the reactor vessel. The proposed license amendment also requested changes to TS definitions and various organizational and program specifications. The following additional information is necessary to complete the Nuclear Regulatory Commission (NRC) staff's technical review:

RAI-SBPB -01: Technical Specification 5.7.1.7 requires that the shipment of hazardous materials on nearby Interstate 5 and a railroad track be monitored and the results submitted to the NRC every three years. The regulatory basis for this requirement is from Title 10 of the Code of Federal Regulations (10 CFR) 100.10, "Factors to Be Considered when Evaluating Sites." This regulation required, in part, that the Commission consider factors such as the nature and inventory of radioactive materials contained in the facility, the safety features engineered into the facility, and the use characteristics of the site environs in determining the acceptability of the site.

Section 2.2.2.2 of the SONGS Updated Final Safety Analysis Report (UFSAR) described that the closest SONGS Units 2 and 3 safety-related structures to these transportation routes are the fuel handling buildings. This UFSAR Section also describes that the hazards considered on these transportation routes included toxic gases, asphixiants, explosives, and flammable materials.

The Section 3.2.14.2 of the Enclosure to the license amendment request states that the Hazardous Cargo Traffic Report required by TS 5.7.1.7 pertains only to an event postulated to occur in MODES 1 through 6. The NRC staff understands this statement is applicable to toxic gas and asphixiant effects on control room operators. However, the basis for the consideration of operating mode with respect to other cargo is not clear because the hazards considered include explosives, the fuel buildings are the nearest safety related structures to the transportation routes, and these structures contain a substantial inventory of spent fuel. Please clarify the basis for deletion of TS 5.7.1.7 by addressing the considerations described above that are required by 10 CFR 100.10.
