SUBJECT:
NINE MILE POINT NUCLEAR STATION, UNIT NO. 2 - CORRECTION OF SAFETY EVALUATION ON ALTERNATIVE REGARDING EXCESS FLOW CHECK VALVE TESTING FREQUENCY (TAC NO. MB1491)
Dear Mr. Conway:
By letter dated September 17, 2001, the Nuclear Regulatory Commission (NRC) staff authorized a relief for certain excess flow check valves (EFCVs) as a result of your application dated March 27, 2001. Subsequently, by a letter dated June 28, 2002, Mr. B. S. Montgomery of your company informed the NRC of two inadvertent errors in the March 27, 2001, application for relief. Specifically, valves 2RCS*EFV44A and B should not have been included in the list of EFCVs for the subject relief. The list was reproduced in the NRC staffs safety evaluation accompanying the relief.
Enclosed please find a corrected page 2 of the safety evaluation, showing deletion of valves 2RCS*EFV44A and B. Please use this to correct your records.
Sincerely,
/RA by PTam for RLaufer/

The NRC staff has completed its review of the relief request and is providing the following evaluation.
2.0 VALVE RELIEF REQUEST GVRR-8 The licensee requests relief for the following EFCVs from the ASME Code inservice tests that are required to be performed every refueling outage as specified in OM-10, Paragraph 4.3.2.2, and from the bienniel requirements (Paragraph 4.1 of OM-10) of verifying that the valve position is accurately indicated. The relief request allows that a representative sample of the affected EFCVs be tested each refueling cycle (approximately 24 months) such that each EFCV will be tested at least once every 10 years.

Pursuant to 10 CFR 50.55a(a)(3)(i), authorization is requested to implement an alternative to the requirements of OM-10, paragraph 4.1 and 4.3.2.2(e), which specify that position indication of valves be verified at least once every two years; and full-stroke exercising of check valves be conducted during each refueling outage, respectively.
The proposed alternative is to conduct exercising and valve position verification tests on a representative sample of reactor instrumentation line EFCVs in accordance with the proposed amendment for Technical Specification (TS) Surveillance Requirement (SR) 3.6.1.3.9 submitted in letter NMP2L 1996 dated February 5, 2001.
