E4 L. Jordan, Director, Division of Engineering and Quality Assurance. IE

SUBJECT:

DIABLO CANYON DESIGN VERIFICATION PROGRAM - REVIEW OF PHASE II PROGRAM MANAGEMENT PLAN

Reference:

Memorandum from D. G. Eisenhut to R. C. DcYoung, dated August 11, 1982 Per your request we have reviewed the Teledyne program management plan for Phase 11 of the Diablo Cenyon IDVP submitted by letter dated June 18, 1982 and

. have the following corments:

1.

The definition of the scope of the Phase I and Phase II programs makes it difficult to determine which seismic activities are excluded from the Phase I work. Based on the IDVP findings to date and the scope PG1E internal work, the Phase I activities have expanded beyond the f,ormal definition in the NRC Order and potentially impact all aspects of the seismic design. Therefore, a more logical and clear cut definition would consider all seismic related activities in Phase I and all non-seismic related activities in Phase II. Sinre PG&E is currently involved in a major effort in reviewing and reanalyzing structures and equipment, it would make little sense to review areas of the seismic design in Phase II that may be superseded by the current PG&E effort. This connent is similar in context to comment number 2 of my July 30th memorandum to you entitled "Diablo Canyon Design Verification Program" (See Enclosure).

2.

Part of the Phase II program involves review of piping analyses with the

' Phase II cut off date being November 30, 1981.

PG&E is currently review-ing all piping analysis done by computer and, if necessary, will reanalyze these systems using Bechtel's computer program. Therefore, the Phase II program should consider the results of the PG&E effort prior to selecting samples for analysis.
