O PSEG Public Service Electric and Gas Company 80 Park Plaza Newark, N.J. 07101 Phone 201/430-7000 February 10, 1983 Director of Nuclear Reactor Reguletion U.S. Nuclear Regulatory Commission 7920 Norfolk Avenue Bethesda, Maryland 20014 Attention: Mr. Albert Schwencer, Chief Licensing Branch 2 Division of Licensing Gentlemen:

HOPE CREEK GENERATING STATION DOCKET NO. 50-354 CODES AND STANDARDS FOR REACTOR COOLANT PRESSURE BOUNDARY EQUIPMENT This letter is in response to NRC staff request, dated November 4, 1981, for further information relating to Public Service Electric and Gas Company's request for authorization to use certain components in its Hope Creek Generating Sta-tion Unit 1, which were designed to codes which differ from those specified in subsections (c) through (f) of 10CFR50.55a.

l Public Service Electric and Gas Company's initial request of January 30, 1979, provided a listing of the reactor coolant pressure boundary components for the Hope Creek Generating Station Unit 1, and indicated the purchase order date and the codes each component is constructed to. As requested by l the NRC staff, the attachment to this letter provides addi-tional information to indicate the codes which are permitted by 10CFR50.55a, and the results of our analysis which iden-l tifies and summarizes for each component the requirements contained in the codes permitted by 10CFR50.55a which are interpreted as being different than the requirements in the code edition and addenda used for construction of the com-ponents. As used in Attachment I, the term " Code of Con-struction" shall mean the code used in the constt3ction, and the term " Code of Comparison" shall mean the code edition and addenda of ASME Section III permitted by 10CFR50.55a.

I Code paragraph references and titles listed in Attachment I l are from the code edition and addenda of ASME Section III l permitted by 10CFR50.55a for each component.

Director of Nuclear 2/10/83 Reactor Regulation The design, fabrication, and testing of these components are in accordance with the recognized codes and standards in ef-fect at the time the components were ordered and provide an acceptable level of quality and safety. Public Service Electric and Gas Company believes that the revisions identi-fied to the " Code of Construction" do not increase the level of quality and safety to compensate for the severe hardship that would be encountered in meeting all requirements of the later codes.

We trust that this transmittal fulfills the NRC staf f 's re-quest for additional information on this matter and will en-able resolution of Public Service Electric and Gas Company's request for an authorization from the Commission in accord-ance with Section 50.55a(a) (2) (i) and (ii) of 10CFR Part 50 to use the codes referenced for the components listed in the attachment to this letter.
