RELIEF REQUESTS ASSOCIATED WITH THE SECOND 10-YEAR INTERVAL INSPECTION PROGRAM VOGTLE ELECTRIC GENERATING PLANT, UNITS 1 AND 2 (TAC NOS. M98977 AND M98978)

Dear Mr. McCoy:

By letter dated May 29,1997, Southem Nuclear Operating Company, Inc. (SNC), submitted the Vogtle Electric Generating Plant, Units 1 and 2 (Vogtle), second .10-year interval inservice inspection program with associated requests for relief from certain provisions of the American

- Society of Me ,hanical Engineers (ASME) Boller and Pressure Vessel Code (ASME Code),

Section XI By letters dated September 10 and 17,1997, SNC provided additional information in response to an NRC Request for AdditionalInformation, dated August 8,1997.

The staff has completed its review of the relief requests. The staff concludes that for RR 17 and RR-25, the proposed attematives provide an acceptable level of quality and safety, and therefore, pursuant to 10 CFR 50.55a(a)(3)(i), the proposed alternatives are authorized. The proposed alternative contained in RR 26 is authorized, pursuant to 10 CFR 50.55a(a)(3)(i), for Class 1 systems only. The use of the proposed alternative for Class 2 and 3 systems is denied because the frequency of once per period proposed for insulation removal has not been shown to satisfy 10 CFR 50.55a(a)(3) authorization criteria. For RR-22, the use of Code Case N 544 as an alternative to Code requirements is denied because SNC did not provide an adequate technical basis to show that Code Case N-544 provides an acceptable level of quality and safety. The bases for these conclusions is described in the staff's Safety Evaluation (enclosed).

If you have any questions regarding this response to your requests, please have your representative contact Duke Wheeler at (301) 415-1444.
