1.
Section 4.2 - The design audit plan should discuss the guidelines to be used in detennining the appropriateness of design methods.
Since
" state of the art" evaluation techniques have changed since truch of the Diablo Canyon evaluations have been perfonned, how will these changes be evaluated?
2.
Section 5.0 - For the independent sample calculations, will current evaluation techniques be used in analyzing the structures and components? The sampling plan implies that the sample will.be expanded each time an independent evaluation gives results not within 15% of the original calculations.
Will this expansion of the sample size be automatic if the 15% criteria is exceeded or will there be an interpretation of the results on a case basis?
3.
Senion 6.0 - Will the independent field verification include piping ard supports which were previously covered by IE Bulletin 79-14 work?

DEC 171981 MEMORANDUM FOR: Chaiman Palladino Comissioner Gilinsky Comissioner Bradford fomissioner Ahearne Comissioner Roberts FROM:
William J. Dircks.
Execut,ive Director for Operations
SUBJECT:
INVESTIGATIONINTOCIRCUMSTANCESSURROUNDINGTHEDEVELOPNENT 0F THE " PRELIMINARY REPORT, SEISMIC REVERIFICATION PROGRAM" PREPARED By R.'L. CLOUD ASSOCIATES, INC. FOR PG&E I have directed an investigation into this issue. The. reasons for this action and the details of the investigation are described below.
Background
Congressman Udall's office advised us by telephone in late November that they had received infomation that Cloud' Associates had circulated an early draft of the subject report in October for coment by PG&E. On.the basis of this information, Region V obtained from PG&E on December 1 a draft with a transmittal letter from Cloud dated October 21. Before a staff review could be completed, Congressman Panetta's office provided EDO with excerpts from a marked-up copy of the same draft on December 10, 1981 which indicated that l
circulation had taken place within PG&E which may have compromised Cloud Associates independence as an auditor. A factor bearing on this judgment was the statement made at a Cloud Associates /PG&E/NRR meeting on November 3 which led us to believe that no circulation preliminary to the draft provided NRC in November had taken place. Based on further inquiries by Region V, Cloud provided NRC additional PG&E mark-ups on the October draft. Ori December 14, 1981 EDO requested Region V to initiate an investigation.
Investigation Responsibilities: NRR will undertake review of the marked-up copies
'of the October draft Cloud Associates report against the draft received by NRC in November. Region V will conduct interviews -(under oath with transcripts) with involve.d Cloud Associates and PG&E personnel. Region V will meet with senior staff from NRR, IE and OEDO in order to obtain a peer review of the_ scope _aad findings of the investigation prior to finalizatio$.
