4 t
l Dr. George Apostolakis, Chairman of the Subcommittee on Reliability and I
Probabilistic Risk Assessment (RPRA) introduced the topic to the Committee. He l
stated that the purpose of this meeting was to discuss the draft Commission paper, j
" Plans to increase Performance-Based Approaches in Regulatory Activities." This paper addresses the staff's proposed plan for increasing, when appropriate, the use of performance-based approaches to regulation. This paper is also intended to provide early input to the development of Strategy 5 of the NRC Excellence Plan.
I j
NRC Staff Presentation l
Mr. Joseph Murphy, RES, provided a brief presentation to the Committee. He noted that the staff previously met with the ACRS Subcommittee on November 13,1997, and February 20,1998, to discuss issues related to performance-based regulation.
The staff discussed the following points during its presentation:
Performance-based regulation should focus on evaluating the acceptability of outcomes or results. Desired outcomes include: improved health and l
safety, cost effectiveness, efficiency, and increased confidence with non-l prescriptive methods.
The regulatory focus should be on monitoring effectiveness and corrective actions.
Key attributes of a performance-based regulatory system include: measur-able, calculable, or observable parameters; quantitative or qualitative i
objective performance criteria; licensee flexibility in meeting criteria, and maintaining adequate safety margins.
l Major changes to the draft Commission paper since the February 20,1998 briefing, include the recognition that performance-based approaches are not a panacea for all regulatory activities and the development of a plan that is strongly based on Strategy 5 of the NRC Regulatory Excellence Plan.
Strategy 5 is intended to develop a process and identify candidate issues for improving the effectiveness of rules, regulatory guidance, and their application, t
1 451st ACRS Meeting 3
J April 2:4,1998 I
The staff is proposing this to be an agency-wide initiative which considers reactors, waste, and materials program and licensing areas. Elements of the H
plan include: stakeholder input, data collection and analysis of information,
[
screening of regulatory activities, and follow-up activities leading up to and j
including final resolution.
-l Drs. Apostolakis and Wallis questioned the staff view that regulations in 10 CFR Part 20 to maintain exposures as low as reasonably achievable (ALARA) are performance-based. Dr. Powers, Dr. Seale, and Mr. Barton supported the staffs position and stated that Al ARA may represent a very good example of goal-oriented or performance-based regulation. Dr. Apostolakis suggested that the regulations should ensure that core damage frequency (CDF) is maintained as low as is reasonably achievable. He stated that the ideal performance-based system would be at a high level or as close to the quantitative health objectives (QHOs) as i
possible. Dr. Apostolakis also suggested that a research project be initiated in this area. The staff stated that it would be good to do such research, but noted that there may be some difficulty in obtaining funding relative to other research priorities.
Dr. Wallis questioned the objectives and milestones for completion. In particular, he questioned whether they could be more specific. The staff stated that they expect to receive considerable input from stakeholders and suggested that the disparity in responses will likely result in more specific objectives and milestones for the various groups or types of licensees.
The Committee requested copies of the related Staff Requirements Memoranda (SRMs), a copy of Strategy 5, and the transcript from the Commission briefing on fire prntection. These documents were provided to the Committee during the meeting. The Committee also requested a follow-up discussion with the staff regarding these matters. Mr. Murphy provided detailed discussion and answered questions during a meeting session on April 3,1998.
Conclusion The Committee provided a letter to the Executive Director for Operations dated April g,1998, on this matter.

AP800 DESIGN (Open)
[ Note: Mr. Noel F. Dudley was the Designated Federal Official for this portion of the meeting.)
Mr. John Barton, Chairman of the Advanced Reactor Designa Subcommittee, noted that the Subcommittee had met with representatives of Westinghouse Electric Company and the staff for the past day and a half to discuss AP600 Stindard Safety Analysis Report (SSAR) Chapters 2,9,10,12,13 (the security section only),
and 15, and the associated draft Final Safety Evaluation Report (FSER) chapters.
Mr. James Winters, Westinghouse, described the design elements in SSAR Chapter 9, " Auxiliary Systems," that are different from past practices. He identified the different components and subsystems described in SSAR Chapter 10 " Steam and Power Conversion," and presented the design bases and analyses results contained in SSAR Chapter 12, " Radiation Protection." He concluded that these SSAR chapters are adequate to support the AP600 design certification.
l Mr. Brian McIntyre, Westinghouse, presented the design information contained in SSAR Chapter 2, " Site Characteristics." He exp!ained the advantages of the proposed security design described in SSAR Chapter 13, " Plant Operations." Mr.
McIntyre explained the regulatory requirements and criteria for loss-of-coolant analyses and presented the analyses results and conclusions, which are contained in SSAR Chapter 15, " Accident Analyses."
He described the radiological consequences analysis contained in Chapter 15 and explained the differences in the analysis from the methodology and criteria used for current operating plants.
Mr. Thomas Kenyon, NRR, stated that the staff had completed its review of the SSAR Chapters under discussion and had identified no open items.
The Committee Members, staff, and Westinghouse discussed the following:
calculation of site-specific atmospheric dispersion factors; security design restrictions that may adversely effect safety; assumptions used in calculating the design basis source term; assumptions used in estimating the containment leak rate; and clarity of exposition and intelligibility of the SSAR and FSER.

UPDATED SOURCE TERM FOR OPERATING PLANTS (Open)
[ Note: Mr. Paul A. Boehnert was the Designated Federal Official for this portion of the meeting.]
Introduction Dr. Kress, cognizant ACRS Member, introduced this topic to the Committee. He noted that the Office of Nuclear Regulatory Research (RES) was tasked with evaluating the impact of the use of the new source term for operating plants. This new source term was developed by the staff, as a result of insights gained from I
severe accident research programs, and documented in NUREG-1465, " Accident Source Terms for Light-Water Nuclear Power Plants".
Dr. Powers recused himself from participation in this session, due to conflict-of-interest concerns. Dr. Kress declared himself in conflict with a portion of the discussion pertaining to use of the TRENDS code, and development of specific values cited in NUREG-1465.
NRC Staff Presentation Details of the source term rebaselining program and the current work status were presented by Mr. C. Ader, RES. In discussing the background, Mr. Ader said that NRC will proceed with rulemaking, subsequent to completion of the rebaselining work, to allow operating plants to make use of the new source term.
The rebaselining effort is designed to develop an understanding of the impacts of implementing the revised source term for operating reactors. The work will proceed in four Phases, in which design basis accident dose calculations will be made with various assumptions for plant operational parameters pursuant to the: Safety Evaluation Report requirements (Phase 1), Final Safety Analysis Report require-ments (Phase 11), updated source term (Phase 111), and proposed plant changes (Phase IV). At present, RES has completed approximately 70% of Phase 111.
Preliminary evaluations of the change to plant risk with use of the revised source term show little impact for such parameters as: containment leak rate, spray operation, filtration systems, and reactor building drawdown time.
In response to Dr. Miller, RES staff said that no " cliffs" have been seen in using the i
NUREG-1465 source term. Dr. Seele inquired as to the impact of the new source term on spent fuel pool risk during shutdown operations. Dr. Kress opined that the 1
l
f
.451st ACRS Meeting 7

source term for this item would be of the same magnitude, but the release timing would be significantly different (~seven days vs hours).
Mrc R. Emch,- NRR, discussed the status of the rulemaking plan for use of the revised source term. The current schedule calls for a Proposed Rule and i
Regulatory Guide (R.G.) to be submitted for Commission review in July 1999. The Final Rule and R.G. would be submitted for review in February 2000. Five i
licensees have applied to make use of the new source term under a Pilot Plant project, in order to gain some regulatory relief in the near term. These applications are under review and should be completed by the end of this year.
Dr. Seale asked if any licensees have applied for relaxation of,statt times for the emergency diesel generators. NRR said that none have been received to date, but such applications are expected. The staff indicated that approval of such requests may be granted, absent a detailed submittal.
I Conclusion This briefing was for information only. No Committee action was required.
VI.
ELEVATION OF CORE DAMAGE FREQUENCY (CDF) TO A FUNDAMENTAL SAFETY GOAL AND POSSIBLE REVISION TO THE SAFE 1Y GOAL POLICY STATEMENT (Open)
[ Note: Mr. Michael T. Markley was the Designated Federal Official for this portion of the meeting.)
Dr. George Apostolakis, Chairman of the RPRA Subcommittee, introduced the topic to the Committee. He stated that two past Committee letters had recommended that core damage frequency (CDF) be elevated to the same level as the quantitative health objectives (QHOs). He noted that the Committee had reviewed these matters during the March 2-4,1998 ACRS meeting. Dr. Apostolakis stated that a Subcommittee meeting is planned for April 16,1998, to continue discussion of issues related to the elevation of CDF and possible revision to the Commission's Safety Goal Policy Statement. The Subcommittee previously met with the staff on February 20,1998, to discuss these matters.

' April 2-4,1991)
NRC Staff Presentation Messrs. Thomas King and Mark Cunningham, RES, and Gary Holahan, NRR, led
{
the discussion for the NRC staff. The staff discussed the following points during its presentation:
The draft Commission paper, " Modifications to the Safety Goal Policy Statement."
Issues under consideration for possible rsvision to the Policy Statement include:
Elevating CDF to a fundamental goal, Defining a societal risk goal, Establishing a goal with respect to potential land contamination or environmentalimpacts, and Establishing a goal on risks during temporary plant configurations.
Other clarifications on the role of Safety Goals include:
Definition of goals on "how safe is safe enough,"
Relationship between Safety Goals and recent risk-informed regulatory activities, Use of Safety Goals to define " adequate protection,"
Relationship between Safety Goals, PRA, and defense-in-depth, and Discussion of Regulatory Analysis Guidelines metrics for screening issues.
Staff conclusions include:
An immediate update of the Policy Statement is not needed to address current issues.
Changes are needed to make the Policy Statement consistent with current practice (e.g., plant-specific application of Safety Goals, treatment of uncertainties in plant-specific decisionmaking, and removal of the plant performance guideline for large releases).
The impact related to materials licensees needs further study.
Staff resources needed to update the Policy Statement may be better allocated to other activities in the near future.
Modification to the Policy Statement should be deferred one year.
l:
451st ACRS Meeting 9
April 2-4,1998 1
The staff requested a Committee report regarding the subject draft Commis-sion paper and staffs proposal to defer revising the Policy Statement for l
about a year.
l Dr. Wallis questioned the meaning of CDF. Dr. Powers noted that it is considered the onset of core damage or the beginning of core melt. The staff stated that the goal in managing CDF is the prevention of core damage and stated that it is linked to the plant source term.
Dr. Apostolakis questioned the staffs view on the benefit of establishing a goal of 10d CDF/ reactor-year and a nonacceptance limit of 108 CDF/ reactor-year. The staff stated that establishing a numerical structure for decisionmaking is different from Safety Goals as they exist today. The staff added that the goal should be to make the reactors as safe as practicable. Dr. Powers stated that this may be asking more of the Safety Goals than was initially intended. He also suggested that consideration of CDF and Safety Goals may be unnecessarily complicated by issues such as land contamination. Dr. Fontana expressed the view that land contamination must be addressed. Dr. Krass stated that the purpose of the Policy Statement is to present the regulatory philosophy. He noted thet problems arise when philosophy is confused with requirements. Dr. Kress stated that the staff should avoid complicating the Policy Statement with an attempt to redefine adequate protection.
Conclusion The Committee plans to continue its discussion of this matter during the May 1998 ACRS meeting.

PROPOSED FINAL STANDARD REVIEW PLAN (SRP) SECTION AND REGULA-TORY GUIDE FOR RISK-INFORMED. PERFORMANCE-BASED INSERVICE INSPECTION (ISI)(Open)
[ Note: Mr. Michael T. Markley was the Designated Federal Official for this portion of the meeting.]
i Dr. George Apostolakis, Chairman of the RPRA Subcommittee introduced the topic to the Committee. He stated that the Committee had reviewed the draft version of Standard Review Plan Section 3.9.8 and Regulatory Guide 1.178 (formerly DG-1063) in July 1997 regarding risk-informed inservice inspection (ISI) for piping. He stated that the staff would discuss the proposed final version of these documents and changes made in response to public comment during this meeting,
451st ACRS Meeting 10 April 2-4,1998 NRC Staff Presentation Mr. Thomas King, RES, and Gary Holahan, NRR, led the discussions for the NRC staff. Messrs. Jack Guttman, RES, and Jack Strosnider, NRR, provided supporting discussion.- Messrs. Goutam Bagchi, Syed Ali, and Stephen Dinsmore, NRR, also participated. The staff discussed the following points during its presentation:
The staff requested a Committee report supporting issuance of these documents for use by the industry and staff.
Thirteen responses were provided by the industry and public in response to the NRC solicitation for comment. Major comments include:
1 Most comnents were supportive of the SRP Section and associated Regulatory Guide.
There was a recommendation to specifically incorporate the method (qualitative) proposed by the Electric Power Research Institute (EPRI).
There was a recommendation that the Appendices to the Regulatory Guide should be deleted. The subject Appendices provide for use of the method (quantitative) proposed by the Westinghouse Owners' Group /American Society of Mechanical Engineers (WOG/ASME).
The use of partial scope probabilistic risk assessments should be allowed.
Both EPRI and WOG/ASME have submitted Topical Reports supporting their approaches.
Key attributes of SRP Section 3.9.8 and Regulatory Guide 1.178 include:
Provide for an acceptable attemative per 10 CFR 50.55a(a)(3)(l).
Allow for either quantitative or qualitative approaches.
Build on SRP Chapter 19 and Regulatory Guide 1.174 (General Guidance), industry topical reports, and the ASME Code Cases.
Allow changes to ISI methods, locations, and frequencies.
Allow partial scope submittals.
Do not allow elimination of ISI for Class-1 piping.
Remove references to the current licensing basis (CLB).
l
451st ACRS Meeting 11 April 2-4,1998 '
}
Industry Presentation Mr. Dennis Weakland, Duquesne Power Company, led the discussions for the WOG/ASME approach. Mr. Ken Balkey and Nancy Closky, WOG, and Mr. Emle Throckmorton, Virginia Power Company, provided supporting discussion. Industry representatives discussed the following points during their presentation:
A large number of plants are approaching their 10-year ISI interval and timely approval of a safety evaluation report (SER) approving the WOG/ASME Topical Report is needed.
Industry representatives contend that approval of the propeeed approach will result in significant savings in occupational raoiation exposure to workers and economic savings in outage completion time.
Additional industry interest is unlikely unless the Topical Report and/or SRP Section and Regulatory Guide are approved. There are no new pilot plants waiting to provide submittals.
WOG/ASME supports keeping the Appendices in the Regulatory Guide.
Messrs. Steve Gosselin, EPRI, and Patrick O'Regan, Duke Engineering and Services Company, provided discussion on the EPRI approach.
Industry representatives discussed the following points during their presentation:
EPRI supports the general guidance provided in the main body of SRP Chapter 3.9.8 and proposed final Regulatory Guide 1.178.
EPRI recommends the Appendices to Regulatory Guide 1.178 be deleted or that the level of detail be eliminated and more emphasis be provided on the principles and references.
There is greater uncertainty with the state-of-the-art for PRA modeling of piping for ISI than in most other risk-informed applications.
Less than full-scope PRAs should be permissible for limited scope applica-tions.
The use of expert opinion should not be framed as an alternative approach, but as a necessary part of any piping reliability assessment.
1
451st ACRS Meeting 12 April 2-4,1998 ASME has approved the Code Cases (N560, N577, and N578) for ISI.
Dr. Apostolakis questioned why the discussion of changes to the CLB was removed from the documents. The staff stated that the Office of the General Council (OGC had objected to its inclusion because it described CLB per 10 CFR 54 for license renewal versus the unique definition that exists for each current operating plant.
Dr. Apostolakis questioned why it was decided to remove the Appendices from the Regulatory Guide. He stated that the main body is not understandable without the Appendices. The staff stated that the Appendices were removed because they had not been fully tested at the pilot plants and that they were trying to be responsive to public comments. Dr. Apostolakis suggested that the staffintegrate some of the key points from the Appendices in the main body. The staff agreed to consider this suggestion.
At the conclusion of the meeting, Dr. Apostolakis suggested that the Committee prepare a report after the staff completes its revision of the Regulatory Guide and SRP Section to incorporate important information now provided in the Appendices.
The eff stated that the subject documents should be issued for trial use rather than issued as final guidance.
Conclusion The Committee deferred issuing a report on this matter, pending receipt of the revised SRP Section and Regulatory Guide. The Committee plans to continue its discussion of this matter during the May 1998 meeting.

CONTINUED NEED FOR THE NUCLEAR SAFETY RESEARCH REVIEW COMMIi i t-E (NSRRC) FUNCTION (Open)
[ Note: Dr. Medhat El-Zeftawy was the Designated Federal Official for this portion of the meeting.]
Former NSRRC member Dr. Neil Todreas, Massachusetts Institute of Technology, stated that in 1988, the NSRRC was formed under the Federal Advisory Committee Act pursuant to a recommendation from the National Research Council. The National Research Council believed that the NRC Research Program lacked direction and a coherent and effective set of principles for organizing an integrated program of research. The National Research Council recommended that "the USNRC Director of Research must establish and maintain good, fundamental research practices, including... establishment of a strong advisory group' that
i 451st ACRS Meeting 13 April 2-4,199$
y includes independent experts from industry and academia, along with representa-tives of organizations performing research."
4 Dr. Todreas stated that the charter of the NSRRC included assessment of and recommendations concoming the following:
Conformance of the NRC nuclear safety research program to the NRC philosophy of nuclear regulatory research as stated in the Commission's Strategic Plan, and to specific Commission directions; Likelihood of the program meeting the needs of the users of research; Appropriateness of the longer range research programs and the correctness of theirdirection; Whether the best people are doing the work at the best places; whether there are other options, including cooperative programs, that would yield higher quality work, or otherwise improve program efficiency; and Whether the program is free of obvious bias, and whether the research products have been given adequate, unbiased peer review.
On a continuing basis, the NSRRC will provide advice to the Director of Research and through him the Commission, on matters of overall management importance in the direction of the NRC's program of nuclear safety research. The Re-search /NRC Safety Research Philosophy Statement included the scope and principles that govem the definition, planning, conduct, and use of research projects. The purpose of research is to provide independent expertise and information for timely regulatory judgments, and to anticipate problems for which new or expanded knowledge can assist the NRC in its mission.
The NSRRC's review and observations included the following :
Review of NSRRC membership NRC RES management Contractor selection Research product quality Research topic definition Dr. Todreas outlined some examples of NSRRC success, such as the focus on user needs, constructive dialogue with RES, and the concept of closure embedded at the
l
'451st ACRS Meeting 14 April y,1998 i-start of research projects that was achieved in issues such as aging and severe accident research. In addition, some research topics were reopened as a result of
- 4 NSRRC review (e.g., TMI-2 accident analysis and seismic hazard ). Some " failure"
- l examples are procurement process revision, management and organization of research, and RES personnel upgrades.
The Commission approved the transfer of the NSRRC function to the ACRS and instructed the ACRS to take an active role in reviewing ongoing research program activities, and to examine the need, scope, and balance of the reactor safety research program. The Commission also requested that the ACRS consider how well RES anticipates research needs and how it is positioned for the changing environment, and recommend whether the NSRRC function is still needed.
Dr. Todreas recommended that the ACRS consider the following:
Revise the Research Philosophy Statement Prioritize ( by group) areas for research emphasis Scrutinize criteria / practices for selecting individuals / organizations to conduct research with consideration given to quality, long term availability of
' the best performers, and intemal NRC procurement vehicles and their consequences.
Conclusion The Committee plans to develop its position and recommendation regarding the NSRRC function and issue a report to the Commission in May 1998.

LOSS OF SHUTDOWN COOLING EVENT AT RIVER BEND NUCl FAR STATION (Open)
[ Note: Mr. Amarjit Singh was the Designated Federal Official for this portion of the meeting.]
The licensee presented the circumstances surrounding two incidents at River Bend Station involving a !oss of shutdown cooling. The first incident occurred during testing of the alternate decay heat removal (ADHR) subsystem, which resulted in
)
an inadvertent loss of shutdown cooling and caused the reactor coolant temperature to increase. The second event involving loss of shutdown cooling was caused by an inadvertent isolation of the shutdown cooling suction path, i
l
~
451st ACRS Meeting 15 f
April 23,1998
\\
These events were caused by the inadequate operating procedures associated with the establishment and maintenance of shutdown cooling to include complete instructions to administratively protect key shutdown cooling paths. Rather, the licensee relied upon operators to be sufficiently knowledgeable of plant conditions
- and to take appropriate actions to protect the integrity of shutdown cooling.
The NRC staff presented its safety and regulatory conclusions regarding these incidents. The staff stated that the licensee failed to maintain adequate procedures associated with technical specifications and that these deficiencies resulted in enforcement action.
Conclusion This briefing was for information only. No Committee action was required.

[ Note: Mr. Sam Duraiswamy was the Designated Federal Official for this portion of the meeting.]
The Committee discussed the response from the NRC Executive Director for Operations to ACRS comments and recommendations included in the following ACRS report:
EDO letter dated March 23,1998, responding to the ACRS report dated February 19,1998, conceming the ACRS interim letter on the safety aspects of the Westinghouse Electric Company application for certification of the AP600 plant design.
The Committee decided it was satisfied with the EDO response on this matter. With regard to the issue of the Westinghouse APS00 design certification documentation, the Committee does not have a concern relative to its adequacy for safety findings. The Committee does believe, however, that the NRC staff should ensure that the Westinghouse documentation be of sufficient quality to provide a traceable and well-archived licensing basis for the AP600 design celtification.
C.
Report on the Meeting of the Planning and Procedures Subcommittee (Open)
The Committee heard a report from Chairman Seale and the Executive Director, ACRS, on the Planning and Procedures Subcommittee meeting held on April 1,1998. The following items were discussed:
1.
INTERNATIONAL MEETINGS (Open)
The Secretary of the British Advisory Committee NUSAC, Mr. Paul Raynesford, called in response to a letter from ACRS suggesting a meeting between the two Committees. Mr. Raynesford stated that the next NUSAC meeting would be held in Scotland on July 1-2,1998.
Unfortunately, the only time available to meet with members of the ACRS would be one hour on July 1st and at dinner that evening. The NUSAC meetings are closed and ACRS members would not be able to attend the meeting on July 2nd. Due to the limited time available for exchanging views with NUSAC during their July meeting, it is
451st ACRS Meeting 18 April 2-4,1991) suggested that only the ACRS Chairman and Executive Director attend this meeting and that arrangements be made for the two committees to meet at a later date.
RECOMMENDATION The Subcommittee recommended that the ACRS staff contact l
NUSAC and determine a possible date for the two Committees to i
meet in 1999.
The Quadripartite Meeting is scheduled for October 5-9,1998, which is immediately after the October ACRS meeting. In order to provide adequate time for the Members to retum home after the ACRS meeting and depart for Japan to attend the Quadripartite Meeting, the Subcommittee recommended that the October ACRS meeting be held from Wednesday, September 30 (1:00 P.M.) through Friday, October 2,1998.
l The Committee agreed to pursue the possibility of a meeting with l
NUSAC in 1999. The Committee also agreed to change the dates of l
the October ACRS meeting to September 30 through October 2, 1998.

ACRS RETREAT FOLLOW-UP 4
The minutes for the January 30-31,1998, ACRS retreat were issued on March 13,1998. At this retreat, the Subcommittee made the following decisions:
The ACRS Subcommittee structure should be revised to delete the Auxiliary and Secondary Systems Subcommittee and the tasks assigned to this Subcommittee will be placed under the Plant Operations Subcommittee.- Additionally, responsibilities l
of the various subcommittees were modified. Subsequently,-
ACRS staff identified some alternative and additional changes to the Subcommittee structure.
RECOMMENDATION The Subcommittee structure is being revised to reflect the recommen-l dations made at the retreat. The Subcommittee recommended that

NEW MEMBER SOLICITATION A solicitation for a new ACRS member closed on March 13,1998.
We have received approximately 20 applications. Copies of the resumes are available in the Caucus Room. The ACRS Screening Panel plans to hold interviews during the May ACRS full Committee meeting and make recommendations to the Commission by June 1998. ACRS members will also be able to interview the selected candidates during the May meeting.
RECOMMENDATION The Subcommittee recommended that members review the applica-tions and make recommendations to the Screening Panel through the ACRS Executive Director.
D.
Future Meeting Agenda Appendix IV summarizes the proposed items endorsed by the Committee for the 452nd ACRS Meeting, April 30-May 2,1998.
The 451st ACRS meeting was adjoumed at 12:17 p.m. on Saturday, April 4,1998.
f l.
1 451st ACRS Meeting 19 1
Apr12-4,1998 i
l proposed revisions to the Subcommittee structure be provided to the Committee at the May 1998 meeting.
Areas of potential overlap beMeen ACRS and the Advisory Committee on Nuclear Waste (ACNW) were discussed and several decisions were made on the division of responsibilities between the two Committees. A draft letter (pp. 5-8) on Coordination of Efforts was prepared by the ACRS Chairman and Vice Chairman, which was subsequently reviewed by the ACNW Chairman and Vice Chairman.
The ACNW has suggested some revisions to this letter as,d has suggested that, instead of issuing a memorandum between the two committees, a Memorandum of Understanding (MOU) be prepared for the Commission. The ACRS and ACNW staff will prepare a draft MOU for review by both Committees.
RECOMMENDATION The Subcommittee recommended that a draft MOU on the coordina-tion of efforts between ACRS and ACNW be made available to the Committee, if possible, at the May 1998 ACRS meeting.
i The Committee decided that a letter between the two Committee i
Chairmen, with a copy to all Commissioners, was preferable to an MOU. A draft will be provided at the May ACRS meeting.
Several members recommended that the Home Page be improved to allow letters to be found by searching for them by date, title or subject. It was also suggested that viewgraphs be available on the Home Page along with the transcripts. The ACRS/ACNW staff is studying the feasibility of incorporating these suggestions into the Home Page.
RECOMMENDATIOR The Subcommittee recommended that the Committee be kept informed of developments on this issue.
The ACRS Operating Plan must be updated quarterly. The next update is due in July and any comments received from f
the Commission will be incorporated at that time. During the l
l
y L
451st ACRS Meeting 20 t
April 2A,1998 I
June ACRS meeting, the Planning and Procedures Subcom-mittee will review how well the ACRS has met the planned accomplishments during the preceding quarter and report to the full Committee.
l RECOMMENDATION The Subcommittee recommended that the updated plan be provided to the Committee when available.
One of the ACRS goals is to identify new issues. It was suggested that time be set aside during full Committee meetings, having Subcommittees make recommendations, and t
seeking industry input. These suggestions should be dis-cussed and decisions be made on their implementation.
RECOMMENDATION The Subcommittee recommended that this matter be discussed after completion of the ACRS review of the AP600 design and the Safety Research Program Report to the Commission.
3.
ATHEANA PEER REVIEW A meeting to support the peer review of ATHEANA is scheduled for June 10-12,1998, in Seattle, WA. All ACRS members are invited to attend as observers. Members planning to attend should notify the ACRS staff by April 3,1998. ACRS discussion and review of the ATHEANA process will take place during a subsequent ACRS Subcommittee or full Committee meeting.
RECOMMENDATION The Subcommittee recommended that members who plan to attend this meeting inform the ACRS staff and that Dr. Apostolakis, as the cognizant Subcommittee Chairman, be designated to attend as the i
ACRS representative.
