UNITEDSTATES NUCLEAR REGULATORY COMMISSION ADVISORYCOMMITTEEON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 July 16, 1984 Honorable Nunzio J. Palladino Chairman U.S. Nuclear Regulatory Commission Washington, D.C.

20555

SUBJECT:

ACRS REVIEW OF THE REPORT OF THE DIABLO CANYON PEER REVIEW GROUP During its 291st

meeting, July 12-14,

1984, the Advisory Committee on Reactor Safeguards completed its review of a draft report (Reference 1) prepared by the Diablo Canyon Peer Review Group as requested by your memorandum dated July 9,

1984.

This matter was considered during a

Subcommittee meeting held in Washington, D.C.

on July ll, 1984.

During our review we had the benefit of discussions with members of the NRC

Staff, including NRC Inspector, Nr.

Isa Yin, representatives of the Pacific Gas and Electric Company (Licensee),

and representatives of the Independent Design Verification Program (IDVP) organization.

We also heard statements from two members of the public and had the benefit of the documents listed.

The draft report of the Peer Review Group relates to activities under-taken by the Licensee in accordance with the seven conditions imposed by the Commission in the low power license for the Diablo Canyon Nuclear Power Plant, Unit 1.

The report also addresses issues raised regarding the scope and effectiveness of the IDVP and concerns relating to quality.

assurance aspects of the work done by the onsite engineering group.

The Peer Review Group has concluded that the seven license conditions have been addressed satisfactorily by the

Licensee, that the previous conclusions of the NRC Staff regarding the acceptability of the IDVP remain valid, and that the Programmatic Issues concerning the onsite engineering group have been resolved.

Although Nr. Yin participated to some degree in the reviews made by the Peer Review Group, he has concerIIs about the extent of the reviews and the judgmental basis for some of its findings.

We believe that Nr.

Yin's concerns represent a

difference in professional engineering judgment.

We believe that the Peer Review I'roup's review of the Licensee's activities was adequate for the purpose.-
