UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 J\.pril 18, 1978 Honorable Joseph L'l. Hendrie Chairman U.S. Nuclear Regulatory Commission Hashington, DC 20555
SUBJECT:
REPORI' ON ACRS ACTIVITIES:
DECE..,,,lBER 1977 THROUGH APRIL 1978
Dear Dr. Hendrie:
This is a brief report of ACRS activities during the period DeceJT1ber 1977 - April 1978.
Selected topics in this report will be discussed during the next joint NRC-ACPS rreeting.
Review of Operations at "stretch" power During the August, September, and October 1977 ACRS meetings, the NRC Staff discussed with the Committee their plans for approving stretch power operation at the Calvert Cliffs, Palisades, and Maine Yankee nuclear plants.
On November 9, 1977, the Corr.mittee requested additional information regarding the scope and nature of the Staff's reviews in this area in order to develop a mechanism for decisions concerning ACRS involvement in similar future reviews.
'Ihe Director, ONRR responded by rneoo dated December 21, 1977. A meeting of the ACRS Subcommittee on the Safety of Operating Reactors was held on March 22, 1978, to develop additional information on this subject; the Subcommittee plans to recommend an appropriate course of action to the full Committee.
ACRS Comments Concerning the Establishment of a Statutorily Independent, Quasi-Judicial Board for Evaluation of Reactor Accidents Congressman Udall has asked for the ACRS' views and recorranendations re-garding a proposal by Dr. Hal Lewis that a statutory Board, similar to the National TrarlSportation Safety Board, be established to review reactor accidents, determine probable cause, and recommend corrective action to preclude reoccurrence. 'Ihus far, merobers of the Committee Staff have visited the NTSB to discuss their procedures, a Subcommittee has met to consider the matter, and informal discussions have been held with Dr. Lewis.
'Ihe Committee will continue to consider its reply, which has been requested by July 31.

April 18, 1978 New Me.rnber s The COITliilission issued a press release on Dece:~ber 14, 1977 inviting me:nbers of the public to nominate individuals to fill two anticipated vacancies on the Committee.
In response to the press release, forty-six persons were nominated by various individuals and organizations.
The Corr:mittee has considered these nominees and is forwarding its recommendations to you separately.
Planned Meetings wit...11 FRG Reactor Safety Committee and French Groupe Permanent The Committee has made prelL~inary arrangements to meet with members of the Groupe Permanent of France and the FRG Reactor Safety Corrnnittee (RSK}in the United States during Septerriber and November to discuss matters related to reactor safety.
Members of the Committee have met on previous occasions with repre-sentatives of the RSK and the French regulatory organizations including the Groupe Permanent and have found these sessions very informative.
Proposed Use of "Class 9" Accidents in Site Comparisons The Committee has received a copy of a proposal (SECY 78-137) to use assessment of the relative differences in Class 9 accident risks as an element in the comparison of sites when current criteria call for special consideration of alternative sites in environmental reviews.
Since such an approach may have potential L"'!lpacts on safety reviews, the Committee plans to discuss this matter wit..~ the Staff.
ACP..S Fellowship Progra~
Section 6 of the NRC's FY 1978 Authorization Act (PL 95-209) directs the Committee to establish a fellowship program.
vie have been informed that a request to reprogram funds to initiate the fellowship program has not been approved by the House Corrnnittee on Appropriations. The Committee needs guidance regarding co!Y!pliance with this provision of P.L.95-209.
Recent Papers by Dr. Ernest Sternglass Dr. Ernest Sternglass of the University of Pittsburgh forwarded, to an ACRS member, two papers dealing with Strontium-90 levels and changes in cancer mortality near the Haddem Neck and Millstone reactors with a re-quest that the observations reported in these papers be reviewed by the ACRS.
'Ihese papers were transmitted to the National Academy of Sciences National Research Council BEIR Committee for their use in their current reevaluation of the effects of low-level ionizing radiation.

Honorable Joseph April 18, 1978 D'Jna11ic Load Combinations As a result of discussions during several recent ACRS project reviews, the NRC Staff is preparing a study of the rationale and methods for com-bining or not co~bining various dynamic loads such as LOCA and seismic loads which are i..11posed on important nuclear plant structures, systems, and components.
