Docket No, 50-220 Niagara Hohawlc Power Corporation ATTN: Hr. Gerald K. Rhode Vice President Engineering 300 Erie Boulevard Uest Syracuse, Now Yorh 13202 Gentlemen:

RE: Nine ?file Point Ue wish to call your attention to the fact that the inservice,in'spection testing requirenents for AS'ode Class 1, 2 and 3 conponents for nuclear power planta delineated in 10 CFR Part 50.55a were changed by a revision to the regulations published on February 27, 1976 (copy enclosed) ~ The revised regulations require inservice inspection and testing to be perforned in accordance ith the examination and testing requirements set forth in

~

Section XI of ASIK, Boiler and Pressure Vessel Code, and Addenda, A review of the 1974 edition of ASIDE Section ZI indicates that conflicts may occur between these requirements and the technical specifications presently in effect for your facility. To avoid these and future conflicts, you should, in accordance with S50.55a(g)(5)(ii), apply to the Commission for anendnent of your tcchnical specifications. Any such conflicting technical specifications should be replaced with a reference to 10 CPR 50,55a, Sample language for such technical specification changes is provided as an enclosure.

As specified in the revised regulation, for plants arith Operating Licenses issued prior to lfarch 1, 1976, its provisions become effective after September 1, 1976, at 'the start of the next regular 40 month, inspection period, The initial inservice examinations conducted during the first 40 nonth period, and the initial inservice tests of pumps and valves conducted during the first, 20 month period, must comply with the,requirenents in editions of the ASHE Code and Addenda in effect no more than 6 months prior to the date of start of facility commercial operation.

Xf you deternine that conformance with certain ASHE Section XI inservice inspection and testing requirements is inpracticable, you should submit information to the Division of'Operating Reactors to support your determin-ations in accordance with 550.55a(g)(5)(iii) and (iv) ~ Your deterninations should separately identify the specific AQfE Code requirenent that is inpracticable for each affected component. Ue wil.l evaluate your deterninations 'and, if appropriate, grant reli'ef pursuant to %0.55a(g)(6)(i)
