UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 205SI001 April 26, 1999 Mr. James M. Levine Senior Vice President, Nuclear Arizona Public Service Company Post Office Box 53999 Phoenix, AZ 85072-3999
SUBJECT:
PALO VERDE NUCLEAR GENERATING STATION - APPROVAL OF INSERVICE INSPECTION RELIEF REQUESTS 11 AND 12 (TAC NOS.
MA5248, MA5249 AND MA5250)
Dear IVlr. Levine:
By letters dated April20 and 21, 1999, Arizona Public Service Company (APS) submitted Relief Requests Nos. 11 and 12 for the second 10-year inservice inspection interval for the Palo Verde Nuclear Generating Station, Units 1, 2, and 3. APS requested the use of alternatives to certain 10 CFR 50.55a(g) requirements pursuant to 10 CFR 50.55a(a)(3)(i).
The NRC staff has reviewed the requests and our evaluation is provided in the enclosed safety evaluation.
Relief Request No. 11 requests approval to use an alternative to IWA-5242(a) of Section XI to the American Society of Mechanical Engineers Code, which requires that insulation be removed from pressure-retaining bolted'connections during the pressure test of systems borated for reactivity control. The proposed alternative would allow insulation removal and visual examination of the bolted connections to be'done earlier in the refueling outage while the system is depressurized.
Relief Request No. 12 requests approval to use an alternative to IWA-5250(a) which requires that bolting be removed and visually inspected when leakage is detected at a bolted connection during the conduct of the system pressure test. The proposed alternative would allow an evaluation of other factors concerning the leakage joint as a possible alternative to disassembly and visual examination of the bolting.
