SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE RANCHO SECO INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI) PROPOSED LICENSE AMENDMENT NO. 2 (TAC. NO. L23757)
Dear Mr. Redeker:
By letter dated July 29, 2004, the Sacramento Municipal Utility District (SMUD) submitted an amendment request to the U.S. Nuclear Regulatory Commission (NRC) to allow for the storage of Greater Than Class C waste at the Rancho Seco ISFSI. On October 15, 2004, you were notified that the NRC staff had completed its acceptance review of your application and that your application contained sufficient information for staff to perform a detailed technical review.
We also provided you with a schedule for completing the technical review of your application.
The staff has determined that further information is needed to complete its technical review.
The information requested is listed in the enclosure. Additional information requested by this letter should be submitted in the form of revised pages. To assist us in scheduling staff review of your response, we request that you provide this information by December 30, 2004. If you are unable to provide a response by that date, you must notify us in writing, at least two weeks in advance, of your new submittal date and the reasons for the delay. The staff will then assess the impact of the new submittal date and notify you of a revised schedule.
Please reference Docket No. 72-11 and TAC No. L23757 in future correspondence related to this licensing action. If you have any questions, please contact me at (301) 415-8580.
Sincerely,
/RA/

1 ENCLOSURE Request for Additional Information Rancho Seco Independent Spent Fuel Installation Docket No. 72-11 By application dated July 29, 2004, Sacramento Municipal Utility District (SMUD) requested an amendment to the Rancho Seco Independent Spent Fuel Storage Installation (ISFSI) to allow for temporary storage of Greater Than Class C (GTCC) waste at the Rancho Seco ISFSI. This request identifies additional information needed by the Nuclear Regulatory Commission staff in connection with its review of the Final Safety Analysis Report (FSAR). The requested information is listed by chapter number and title in Appendix C of the FSAR, Greater Than Class C (GTCC) Waste Canister. NUREG-1567, "Standard Review Plan for Spent Fuel Dry Storage Facilities," and the Spent Fuel Project Offices Interim Staff Guidance - 17 (ISG-17),
Interim Storage of Greater Than Class C Waste were used for this review. ISG-17 represents recommendations on how to revise NUREG-1567 regarding specific methods that could be used to conduct reviews of site-specific license amendments that request storage of GTCC waste. This request describes information needed by the staff for it to complete its review of the FSAR and to determine whether the applicant has demonstrated compliance with regulatory requirements.
Chapter 1 Introduction and General Description of Installation The following information is needed to assure compliance with Title 10 of the Code of Federal Regulations (10 CFR) 72.120:
1-1 Provide the radionuclide inventory for the GTCC waste.
The radionuclide inventory is one of the key parameters used to describe waste. (See ISG-17, page 7, Section 4.5.1.3) 1-2 Provide the GTCC waste acceptance criteria, including the upper and lower bound limits of acceptable variability. It is the NRC staffs understanding that SMUD is not requesting to store significant neutron source or fissionable material in the GTCC waste canisters at the Rancho Seco ISFSI.
Although process waste and such components are a category of GTCC wastes, they have not been considered in the FSAR for this application. These waste acceptance specifications need to be incorporated in the technical specifications. (See ISG-17, page 7, first paragraph of Section 4.5.1.)
Chapter 3 Principal Design Criteria The following information is needed to assure compliance with 10 CFR 72.122(b):
3-1 State the conclusions and its impact on safety of the GTCC canister seismic loading analysis noted in Section 3.2.1. (See ISG-17, page 5, last paragraph)
Chapter 9 Conduct of Operations The following information is needed to assure compliance with 10 CFR 72.44(c)(3)(i):
9-1 Identify, in the Technical Specifications, surveillance requirements that will be used to inspect and monitor the GTCC waste in storage. (See ISG-17, page 19, Section 9.5.3.2)
Identify procedures to identify and monitor the GTCC waste canister. According to Appendix C, Section 9.4 of the FSAR, the GTCC waste stored within the GTCC waste canister will be identified and monitored, as described in the Rancho Seco procedures.
Identify the program that will be used to conduct visual inspections of the GTCC waste container integrity. According to ISG-17, page 20, the staff should determine whether the applicant has incorporated a program to conduct visual inspections of the GTCC waste container integrity.
9-2 Describe the procedures in place that will maintain confinement during storage and retrieval (if necessary) and that will provide for periodic inspections for potential degradation in confinement.
Inspections should include examination of any degradation (e.g., buildup of corrosion products, holes, swelling) that could affect the structural integrity, shielding effectiveness, or confinement of the GTCC waste. Describe how SMUD plans to handle potential degradation of the confinement system. (See ISG-17, page 19, Section 9.5.3.2 and page 20, Section 9.5.4.2).
According to Appendix C of the FSAR, Section 10.1, controls and limits on the GTCC waste canister will be applied to provide assurance that the ISFSI is unaffected. In Appendix C of the SAR, Section 10.3, operating limits applicable to the SAR are provided. The operational limits for the GTCC waste container helium leakage rate of the inner seal weld is identified and only applies during GTCC waste loading operations.
