SUBJECT:

NORTH ANNA POWER STATION UNIT 1 - ASME SECTION XI RELIEF REQUEST NDE SERVICE WATER SYSTEM (SWS) LEAKS (TAC NO. M98381)

Dear Mr. O'Hanlon:

The NRC staff has evaluated the information provided in your March 3.1997, submittal related to the inservice inspection program relief request NDE-33.

Based on the evaluation of relief request NDE-33 it is concluded 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 re) air during the period January 8. 1997, through January 23, 1997, would lave constituted an undue burden on Virginia Electric and Power Company (VEPCO).

Your aiternative program for this period included evaluation of the flaws which is consistent with the guidelines and acceptance criteria of Generic letter (GL) 90-05. The staff finds the structural integrity and operability assessments to be acceptable. You have stated that during the period of January 8 through January 23. 1997, the welds were monitored by plant personnel and all the flaws were repaired by January 23, 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 impracticality of the sde requirements was not shown, the staff finds that celief may be granted pursuant to 10 CFR 50.55a(a)(3)(ii). The staff's evaluation and conclusions are contained in the Enclosure.
