SUBJECT:
EVALUATION OF INSERVICE TESTING RELIEF REQUEST - LASALLE COUNT / STATION, UNIT 1 (MA3758)
Dear Mr. Kingsley:
By letter dated October 8,1998, Commonwealth Edison Company (Comed) submitted a one-time request for relief from certain provisions of Section XI of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code) pursuant to 10 CFR 50.55a for certain plant safety / relief valves.
As required by 10 CFR 50.55a, inservice testing (IST) of certain ASME Code Class 1,2, and 3 pumps and valves must be performed in accordance with Section XI of the ASME Code, except where altematives are authorized or relief is granted by the Commission pursuant to paragraphs (a)(3)(l), (a)(3)(li), or (f)(6)(i). In order to obtain authorization or relief, the licensee must demonstrate that (1) the proposed alternatives provide an acceptable level of quality and safety, (2) compliance would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety, or (3) conformance is impractical for its facility.
Guidance on acceptable altematives to Section XI requirements for certain aspects of the IST program was provided by the NRC in Generic Letter 89-04.
The staff has reviewed the relief request proposed in your letter of October 8,1998. The alternative you have proposed (a two-month extension of the interval) to the ASME Code testing of the main stesim line safety relief va;ves is authorized pursuant to 10 CFR 50.55a(a)(3)(li) in that compliance with the code require ments would result in hardship without a compensating increase in the level of quality and safety. The specific details are contained in the enclosed safety evaluation.
Sincerely, ORIG. SIGNED BY
