RESAR-414
SUBJECT:
SUMMARY
OF MEETING HELD DECEMBER 1,1978 TO DISCUSS THE RESAR-414 INTEGRATED PROTECTION SYSTEM DESIGN VERIFICATION PROGRAM On December 1,1978, we met with representatives of the Westinghouse Electric Corporation (W) at NRC Headquarters in Bethesda, Maryland.
W requested the meeting in order to discuss with us the current status and future plans for the RESAR-414 Integrated Protection System (IPS)
Design Verification Program. A list of attendees is contained in Enclosure No. 1.
During its introductory remarks, W informed us that, instead of continuing work on the RESAR-414 design effort, it was pursuing prep-aration of an FDA application for the RESAR-412 design which would be tendered in July 1979. This RESAR-412 design would incorporate the same IPS contained in the RESAR-414 design.
It was agreed that further discussion of 'd licensing plans be postponed until the meeting scheduled in the afternoon with hRC regarding standardized designs.
W then described the method which it proposes to use to document the IPS design in the generic sense that will facilitate referencing by applicants in individual case reviews. Enclosure No. 2 contains this proposal. Briefly, this method would use the topical report approach.
The documentation would consist of three parts:
(1) the so-called "I&C" (instrumentation and controls) material normally contained in Chapter 7 of an SAR, (2) and (3) aapendices documenting the Design 2i Verification Program. These would be of two types - (i) tests and i
(ii) analyses.
W reported that the testing aspect of the design verification program Ts currently in progress. Some results should be available in early 1979. 'd then described plans under consideration for the preparation of a Systems Verification Manual. Since proprietary information will be involved, the mechanics of how the staff's review of the test results will be conducted must be worked out with this consideration.

'le expressed concern about how the staff's canpower and resources situation might affect our review of the design verification program.
The ideal situation would be to have our review and evaluation com-pleted before any OL application incorporating the IPS design is submitted for review. Depending upon the staff's manpower require-ments, this may or may not be possible.
We then discussed the staff's requirements for validation and verifi-cation of IPS design which are being developed.
In view of the critical manpower problem, we proposed that further discussions in the form of meetings and telephone conmunications be held so that our review of the W verification program can begin. A meeting was tenta-tively scheduliiid for the period between December 15 and 21,1978. We requested that W examine our guidelines for validation and verification so that at the iiext meeting they can explain how the RESAR-414 IPS design verification program meets our objectives. This explanation should also indicate where, on the record, the documentation describing this conformance is located. We emphasized the importance of getting early resolution of any differences of opinion regarding conformance.
W provided us with a summary of the R&D matters mentioned in the RESAR-4'l4 Safety Evaluation Report along with their current status and future plans if pertinent to the RESAR-414 IPS verification program review.
This information is contained in Enclosure No. 3.
