2. General The Supply System has previously met with NRC representatives to discuss the proposed readiness- review programs for WNP-1 and WNP- In the Supply Systems letter of May 22, 1985, a specific request was made that

,

the NRC agree to review the program description of Readiness Reviews at WNP-3 and WNP-1 for approval, agree to participate in the Readiness Review at WNP-3 and WNP-1 and review the Preservation Program Description for approva In letter G03-85-283 dated May 24, 1985, the Supply System sent a copy of

'

the preservation program entitled " Preservation of Assets Preventative Maintenance Program" for NRC review and approval. The description of the programatic controls for the Preservation Program were subsequently furnished with G03-85-358 dated June 28, 1985, which was also submitted for NRC review and approva In letter G01-85-0127/G03-85-0299 dated June 3, 1985, the Supply System requested review and approval of the Design Review Program entitled

" Engineering Assurance Program (EAP)".

, The purpose of the meeting on July 2, 1985 was to reviev the status of the WNP-3 project and the aforementioned submittals pertaining to the Preservation Program and Engineering Assurance Program. Attached are copies of the slides used by the licensee during the presentation of the proposed programs for NRC consideratio The licensee stated that an independent group from outside the Supply System will be utilized to assess and audit the effectiveness of the Readiness Revie The licensee responded as follows, for specific issues / questions:

An independent group from_outside the' Supply System will be utilized

to assess and audit the effectiveness of the progra Procedures will be developed that detail how each design process review is to be conducted.-

The readiness review will verify that the documentation inventory is complet Maintenance Work Requests are reviewed by Engineering after work has

'

been complete *

The cathodic protection system is On-line and has been balanced several time Generally, the manufacturer's recommendations are followed for l preventative maintenance for the protection of equipment, including 1 l surveillance frequency and insulation resistance test t l,

i The Regional Administratbr expressed concern ~as to the existence of a structured program for configuration control to assure that control over maintenance and work cress inside the plant does not diminish during the years of mothballing; emphasizing the need to make absolutely certain

that if something is'taken apart, it is properly reassembled and documented. . He cautioned that over-the years unusual circumstances can 4 occur. The Supply System.needs to make sure the inventory is complete so

. a new generation can pickup the projec '

Supply System management responded, stating that is the heart of what they are doing and that there have not been any big surprises so far in

the preservation of'the plant.

The only comment from the public was fro a member of EFSEC who stated that the Council supported the Readiness Review and Preservation
