Detroit Edison letter to NRC, " Proposed Technical Specification Change (License Amendment)- Implementation of 10 CFR 50 Appendix J Option B," NRC-95-0133, dated December 21,1995
Subject:
Relief Request for Inservice Testing Program for Pumps and Valves to Implement Test Frequencies Consistent with 10 CFR 50 Appendix J Option B Detroit Edison submitted the Reference 2 proposed License Amendment to implement 10CFR50, Appendix J, Option B When implemented, this license amendment will allow containment leakage rate test frequencies to be specified by performance-based criteria in the Primary Containment Leakage Rate Testing Program, defined in proposed Technical Specification Section 6.8.5.g. In the case of containment isolation valves, the allowable base test intervals may be increased to a maximum of 60 months. The containment isolation valves are also subject to the testing requirements of the Fermi 2 Inservice Testing Program, which in turn, is based on the requirements of Section XI of the ASME Boiler and Pressure Vessel Code, 1980 Edition through the Winter 1980 Addenda. Paragraph IWV-3422 of Subsection IWV states in part that valve leak rate tests shall be conducted at least once every 2 years. In the Implementation Plan provided in Enclosure I to the Reference 2 submittal, Detroit Edison stated that prior to using extended intervals for certain components in excess of ASME Section XI test interval limits, a relief request will be submitted and approved.
Relief Request VR-61 is attached for review and approval so that Fermi 2 can take g g g full advantage of the performance-based containment leakage test frequencies allowed 9604010252 960327 l

USNRC March 27,1996 NRC-96-0036 Page 2 for containment isolation valves by 10 CFR Part 50 Appendix J, Option B. In particular, reliefis requested from paragraph IWV-3422 of the applicable code to the extent that it requires leakage testing at least once every 2 years. The basis for the request is that the proposed alternative provides an acceptable level of quality and safety. This acceptable level of quality and safety has been demonstrated by the NRC at the industry-wide level as the basis for revising 10 CFR Part 50 Appendix J to include Option B. The Reference 2 proposed License Amendment reiterates the applicability of this conclusion to Fermi 2 for the purpose ofimplementing the Option B performance-based requirements. As a result, no additional documentation or justification is provided with the attached relief request to demonstrate that the i
proposed alternative provides an acceptable level of quality and safety.
It is requested that the enclosed relief request be granted concurrent with, or pnor to, 1
the approval of the proposed License Amendment submitted in Reference 2, which requested approval by August 1,1996. This would allow the new Technical Specifications and the changes to the IST program related to containment leak rate testing to be implemented at the same time prior to the beginning of RF05, which is i
scheduled to begin September 27,1996. Implementation of the new Appendix J Technical Specifications prior to the outage will allow the deferral of Type A testing that would have been required during RFOS to a future outage.
Several previously granted relief requests extending the test interval from 3 months to refueling stated that the testing during refueling would be performed as part of or concurrent with LLRTs at test intervals no greater than two years. Fermi 2 plans to revise these relief requests to retain the two-year test interval as granted by the relief requests, but using one of the accepted test methods other than the LLRTs as defined in Generic Letter 89-04 or other related regulatory guidance documents. NRC review and approval is not required for these revisions.
No commitments are being made in this letter. If you have any questions on this matter, please contact Mr. Robert Newkirk at (313) 586-4211.

Enclosure to NRC-96-0036 Page1 RELIEF REQUEST NO. VR-61 SYSTEM:
SYSTEMS PENETRATING PRIMARY CONTAINMENT COMPONENT:
Valves subject to ASME Section XI, Category A Containment Isolation Valve Leakage Tests. See Table VR-61 for a list of valves to which this Relief Request applies.
CATEGORY:
A and A/C FUNCTION: The subject valves perform a containment isolation function as defined in 10CFR50, Appendix A, Criteria 55,56, and 57.
TEST REOUIREMENTS: Per IWV-3422 the subject valves shall be leak rate l
tested on a frequency of at least once every 2 years.
BASIS FOR RELIEF: 10 CFR Part 50, Appendix J, has been revised to allow licensees to implement performance-based containment leak rate test intervals in accordance with Regulatory Guide 1.163, dated September 1995. RG 1.163 endorsed, with specific exceptions, NEI 94-01, Industry Guideline for Implementing Performanced Based Option of 10CFR50, Appendix J, dated July 26,1995. Under certain conditions, the base test intervals for containment isolation valve leak rate testing may be as long as 60 months. The basis for the request is that the proposed alternative provides an acceptable level of quality and safety. This acceptable level of quality and safety has been demonstrated by the NRC at the industry-wide level as the basis for revising 10 CFR Part 50 Appendix J to include Option B. The proposed License Amendment that implements Option B reiterates the applicability of this conclusion to Fermi 2 for the purpose ofimplementing the Option B performance-based requirements.
ALTERNATE TESTING: The Containment Isolation Valves listed in Table VR-61 will be leak rate tested at frequencies specified in accordance with Reg. Guide 1.163, but at base intervals no greater than 60 months.
