UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 January 12, 1978 Honorable Joseph M. Hendrie Chairman
- u. s. Nuclear Regulatory Commission Washington, DC 20555
Subject:
REPORI' ON PEBBLE SPRI~S NUCLEAR PLANT, UNITS 1 AND 2
Dear Dr. Hendrie:
During its 213th meeting, January 5-7, 1978, the Advisory Committee on Reactor Safeguards corrpleted its reviei of the application of the Portland General Electric Corrpany for a permit to construct the Pebble Springs Nuclear Plant, Units land 2. This project was also considered during a Subcommittee meeting held in Portland, Oregon, on October 28, 1977. The Conmittee previously corrpleted a partial review of this project at its 190th meeting, as discussed in its interim report to the Nuclear Regulatory Conmission (NRC) dated February 11, 1976. During its review, the Committee had the benefit of discussions with represen-tatives and consultants of the Portland General Electric Company, the Babcock and Wilcox Corrpany, the Bechtel Power Corporation, and the NRC Staff. The Committee also had the benefit of presentations on the regional tectonics of the Pacific Northwest by representatives of the NRC Staff, the u. s. Geological Survey (USGS), Puget Sound Power and Light Corrpany, Portland General Electric Corrpany, Washington Public Power Supply System, their consultants, and members of the public at Subcorrmittee meetings held on September 1-2, 1977 in San Francisco, California, and on October 27-28, 1977 in Portland, Oregon.
Matters related to the regional tectonics of the Pacific Northwest were con-sidered at the 209th and 211th Cormnittee meetings as reported in the Cornmittee's \
letter dated November 15, 1977 to the NRC Executive Director for Operations. The Corrrnittee also had the benefit of the documents listed.
At the time of the Committee's interim report, February 11, 1976, the NRC Staff, the USGS, and the Appl-icant had not yet completed their re-views of the seismic design basis and of matters related to the possible deposition of volcanic ash arising from major volcanic eruptions of Mount Hood or Mount Saint Bel ens. These reviews have now been co:rrpleted and the ACRS finds the Staff positions on these matters acceptable.

Honorable Joseph M. Hendrie 2 -
January 12, 1978 The Comnittee believes that the Applicant and the NRC Staff should re-view the Pebble Springs Nuclear Plant for design features that could further reduce the possibility or consequences of sabotage.
(Generic Item IIC-2 in ACRS Report, "Status of Generic Items Relating to Light-Water Reactors: Report No. 6," dated November 15, 1977).
Since the Cormni.ttee's earlier partial review, the Staff has identified 13 additional issues, 11 of which require resolution prior to construc-tion. These matters should be resolved in a manner satisfactory to the NRC Staff.
With regard to the generic problems cited in the Cornmittee*s report, "Status of Generic Items Relating to Light-Water Reactors: Report No. 6,"
dated November 15, 1977, items considered relevant to the Pebble Springs Nuclear Plant, Units 1 and 2 are: II-3, 4, SB, 6, 7, 9, 10; IIA-2, 3, 4; IIB-1, 2; IIC-1, 3A, 3B, 4, 5, 6; IID-2; IIE-1. These problems should be dealt with by the NRC Staff and Applicant as solutions are found.
The ACRS believes that, if due regard is given to the items mentioned above and in its report of February 11, 1976, the Pebble Springs Nuclear Plant, Units 1 and 2 can be constructed with reasonable assurance that it can be operated without undue risk to the health and safety of the public.
