SUBJECT:
NORTH ANNA POWER STATION. UNITS 1 AND 2 - ASME SECTION XI RELIEF REQUESTS NDE-44 AND NDE SERVICE WATER SYSTEM (SWS) LEAKS (TAC NOS. M99805 AND M99806)
Dear Mr. O'Hanlon:
The NRC staff has evaluated the information provided in your October 13. 1997, submittal related to the inservice inspection program ralief requests NDE-44 and NDE-39.
Based on the evaluation of relief requests NDE-44 and NDE-39, it is concluded that the repair would have necessitated removing portions of the SWS that are otherwise structurally sound and capable of performing their intended safety function. This would have unnecessarily reduced the margin of safety of the SWS. Therefore, the immediate Code repair during the period September 9, 1997, through September 25, 1997, would have constituted an undue burden on Virginia Electric and Power Ccmpany (VEPCO).
Your alternative program for this pe; tod included evaluation of the flaws which is consistent with the guidelines and acceptance criteria of Generic Letter 90-05.
The staff finds the structural integrity and operability assessments to be acceptable.
You have sttted that during the period of September 9, 1997, through September 25, 1997, the weld were monitored by plant persor.nel and all the flaws were repaired by September 25, 1997.
In addition, you had evaluated the defective areas and determined that the flaws were acceptable and the SWS was determined to be operable.
While the impractical 1ty of the Code require.aents was not shown, the staff finds that relief may be granted pursuant to 10 CFR 50.55a(a)(3)(ii) in that compliance with the Code would have resulted in hardship without a b@\\
compensating increase in the level of quality and safety. The staff's evaluation and conclusions are contained in the Enclosure.
