SUBJECT:
FOUR RELIEF REQUESTS FOR VALVE INSERVICE TESTING PROGRAH-NINE MILE POINT UNIT 1
(TAC NO. H96337)
Dear Hr. Sylvia:
By letter dated August 9,
- 1996, as supplemented February 28,
- 1997, Niagara Mohawk Power Corporation proposed revisions to four relief requests for Nine Mile Point Nuclear Station, Unit 1
(NMP-1), with respect to the second ten-year interval program for inservice testing of valves.
The four requests are identified as:
VG-2, Revision 1;
CS-RR-6, Revision 1;
LP-RR-2, Revision 1;
and CRD-RR-3, Revision 1.
The existing version of these relief requests were previously by the NRC staff in safety evaluations dated March 7, 1991 (Relief Requests VG-2, LP-RR-2, and CRD-RR-3),
and July 26, 1995 (Relief Request CS-RR-6).
As described in the enclosed safety evaluation (SE), the NRC staff has completed its review of the your submittals and concludes that:
1.
The Code requirement for Relief Request CS-RR-6, Revision 1, is impractical to perform and the relief is granted as requested pursuant to 10 CFR 50.55a(f)(6)(i).
2.
For Relief Requests LP-RR-2, Revision 1,
and CRD-RR-3, Revision 1,
your proposed alternative to defer verification of reverse flow closure to refueling outages is approved pursuant to 10 CFR 50.55a(f)(4)(iv) based upon your letter dated February 28,
- 1997, which proposes to meet the requirements of Paragraphs 4.3.2, and 6.2 of OH-10 and reference Section
- 3. 1. 1.3 of NUREG-1482 in the IST program.
3.
For Relief Request VG-2, Revision 1, your proposed alternative to use Option B to 10 CFR 50, Appendix J for leakage-rate testing of LJ containment isolation valves is approved pursuant to the provisions in 10 CFR 50.55a(f)(4)(iv) based upon your letter dated February 28,
- 1997, which proposes to meet OH-10 paragraphs 4.2.2.2, "Containment Isolation Valves;" 4.2.2.3(e),
"Analysis of Leakage-Rates;"
and 4.2.2.3(f), "Corrective Action."
The proposed alt'ernative in relief request VG-2, Revision 1, to not perform the trending required by IWV-3427(b) for LA containment isolation tmC HLE Col'H CSH'703070152 970305 PDR ADGCK 05000220 P

B. Ralph Sylvia valves is approved because you will meet the NRC staff position as stated in GL 89-04, Position 10.
The proposal to leak test the pressure isolation valves in accordance with the technical specifications and the guidelines in NUREG-1482, Section 4.4.7, "Pressure Isolation Valves," rather than IWV-3420 is approved pursuant to 10 CFR 50.55a(a)(3)(i),
since it provides an acceptable level of quality and safety.
You should complete the actions to comply with the provisions in the approval of the alternative testing proposed for relief requests LP-RR-2, Revision 1, CRD-RR-3, Revision 1, and VG-2, Revision 1, within 180 days from the date of this letter.
