Washington Public Power Supply System P.O. Box 968 3000 George Washington Way Richland, Washington 99352 (509) 372-5000 Docket No. 50-397 G02-82-864 October 22, 1'982 Hr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D. C. 20555

Dear Hr. Denton:

Subject:

NUCLEAR PROJECT NO. 2 - VERIFICATION OF DESIGN AND CONSTRUCTION ADEQUACY Enclosed is a copy of a document entitled "WNP-2 Plant Verification Report". This report is being provided for your use preparatory to a meeting between the Supply System and the NRC staff on this subject scheduled for November 10, 1982, in Bethesda, Haryland. The orginal issue of this report was provided informally to R. Auluck of your staff and to NRC Region V. Also, the Region V staff was briefed on our plant verification plans in detail at a meeting in Walnut Creek on June 25, 1982.

The WNP-2 Plant Verification Report presents in a single document the basis for confidence that WNP-2 has been designed and will be constructed to meet applicable Regulatory requirements and Safety Analysis Report commitments. The plant verification programs described in this report are part of a broader "WNP-2 Plant Completion Plan".

The Plant Completion Plan covers:

a) Plant Verification requirements and design verification construction verification performance verification (testing) operating envelope verification b) Construction Completion c) Organization Readiness d) Operational Readiness.

The Plant Completion Plan (which includes Plant Verification as an element) was first conceived as a response to the Supply System's Managing Director's request for a " . . .well documented basis for acceptance of plant completion, safety, and technical adequacy".

This request, issued in January 1981, six months after he assumed pgpI 8210270013 821022 Lp PDR ADOCK 05000397 (

0 H. R. Denton Page 2 October 22, 1982 WNP-2 Verification of Design and Construction Adequacy the Directorship, came during a one year construction suspension required to correct prior quality problems of several construction contractors. This program, when fully implemented,-will provide the basis for certification by the Supply System Chief Executive of readiness to proceed with safe operation of WNP-2.

The Plant Verification Report describes the programs which were conducted or begun during the suspension to identify and correct deficiencies and re-establish an adequate quality level for completed work. It also describes the changes in management practices which the Supply System adopted to correct these early construction problems, including the employment of a more experienced construction management/

systems completion contractor to assist in maintaining a high level of quality following construction restart in June 1981.

In addition to re-establishing the construction quality baseline for past work and describing methods for assuring that it will be continued to completion, the report also describes the bases for confidence in the design as developed by the architect-engineer and the nuclear steam supply system contractor. When both are complete, these design and construction verification activities would, under normal circumstances, be sufficient to demonstrate the technical adequacy of WNP-2.

However, in response to the Managing Director's request for an acceptance review, and noting the design quality. problems encountered at Diablo Canyon and elsewhere, the Supply System has decided to take several additional steps which go beyond normal practice, and which address NRC's concerns for strengthening quality assurance for nuclear plants under construction. These include a reverification that the design requirements for all safety systems are complete and clearly documented and, by independent design reviews of three selected systems confirm that these requirements were correctly reflected in the detailed design documents used in construction. 'Any deficiencies noted in these reviews will be submitted to an independent "findings review committee" for evaluation and disposition. The Plant Verification Program and the implementation of several of its critical elements will be subjected to independent technical audit by an outside firm.

The Supply System believes that the Plant Verification Program described here will, when complete, provide confidence that WNP-2 is designed and constructed in accordance with committed requirements.

Very truly yours, G. D. Bouchey, N ager Nuclear'Safety 8 Licensing GDB/sm Attachment cc: NS Reynolds . TH Novak A Schwencer DG Eisenhut A Auluck RH Engelken
