. September 3-5, 1997 II. STAFF ACTION PLAN TO IMPROVE THE SENIOR MANAMRMENT MRETING PROPRRE. EECY-97-072 (Open)
[ Note: Mr. _ Paul A. Boehnert was the Designated Federal Official for this portion of the meeting.] -
Mr. Barton, Chairman of the Plant Operations Subcommittee, introduced the cognizant NRC staff represenmtatives present.
He noted that, as a result of the August 28, 1997 meeting of the Combined Subcommittees on this topic, a series of ques-tions were posed for staff response at this time. Mr.-Barton also said that the staff was asked to provide a status report on its efforts to perform an integrated review of; the NRC assessment process for operating plants.
Mr. Michael Johnson, Office of Nuclear Reactor Regulation (NRR), provided a status report on NRR's plans to perform an integrated review of the NRC plant assessment process. He discussed the central elements of the current assessment process: Systematic Assessment of Licensee Performance, the Senior Management Meeting (SMM), the Plant Performance Review, and the Plant Issues Matrix. Dr. Powers asked why the current process missed the problems seen at the Millstone plants. Mr.
Richard Barrett, Office for Analysis and Evaluation of Operating Data (AEOD), stated that, while problems were known to exist, there were no clear criteria available as to which type of regulatory action should be taken in this situation.
The staff noted that an integrated Review Plan is under development, partly in response to several Commission Staff Requirements Memoranda (SRM). The Plan will focus on ensuring that the assessment process emphasizes early identification of declining licensee performance and an open dialogue of assessment results with the industry and public. Efforts will be taken to minimize both the issuance of conflicting messages on plant performance and excessive administrative requirements to implement the assessment process, i
)
. 'l, '
444th ACRS Meeting 3 September 3-5, 1997 Dr. Apostolakis stated that the decisionmaking process used for plant assessment should reflect use of a risk-informed approach. Dr. Powers questioned the staff regarding the development of a specific list of requirements that will be addressed by the Review Plan. The staff indicated that they have not developed such requirements and they need to consider this point.
The staff is scheduled to develop the Review Plan by June 1998 for the Commission's consideration. The Plan is scheduled to be implemented in December 1998.
Mr. Barrett discussed improvements planned to the information base of the SMM. He discussed the performance assessment information, the SMM information flow, and the components of the performance Template. During discussion of these issues, Drs. Seale, Kreas and Apostolakis suggested that AEOD obtain information from the Institute of Nuclear Power Operations (INPO) and the International Atomic Energy Agency on what attributes contribute to a plant that is considered a " good performer." Dr. Powers also observed that the nuclear industry deserves praise for the extensive sharing of informa-tion that has become the norm. He expressed the Pope that such information sharing would not become a casualty of rate competition.
Comments and questions posed during the August 28 Combined Subcommittee Meeting were discussed by Mr. Barrett. He noted that the comments included suggestions that AEOD develop a model basis for its Template and an examination of a sample of significant plant events to determine if prior performance foreshadowed these events. AEOD agreed with these sugges-tions. Mr. Barrett acknowledged that the Subcommittee was also uncomfortable with NRC's use of economic performance indicators.
Specific questions posed by the Subcommittee and Mr. Barrett's responses (in parentheses) were:
J a*
. '. .g.-
O 444th ACRS Meeting 4 September 3-5, 1997 How will the revised SMM process focus on organizational culture and management competency? (The staff will infer the effectiveness of the organization.)
How do indicators assess the timeliness of corrective action programs? (This issue will be addressed via the Template development activities.)
How is the staff assuring that new performance standards are " objective?" (The staff will not be using subjective information to develop performance standards.)
Will the new standards reduce reliance on event-driven assessments? (Yes, the staff will evaluate plant-performance-related data through use of the Template.)
What is being done about consistency among NRC assessment processes? (This is being evaluated via the integrated review process.)
The staff is scheduled to brief the Commission on September 19, 1997 on this matter. Draft reports will be made available for ACRS review in the Fall of 1997, and a Commission Paper is due by the end of 1997.
Conclusion The Committee issued a report to Chairman Jackson, dated September 10, 1997, on this matter.
III. DRAFT REGULATORY GUIDE DG-1069; FIRE PROTECTION PROGRAM FOR PERMANENTLY SHUTDOWN AND DECOMMISSIONING NUCTMR PLANTS (Open)
[ Note: Mr. Amarjit Singh was the Designated Federal Official for this portion of the meeting.]
, *j,
- 444th ACRS Meeting 5 September 3-5, 1997 Introduction Dr. Powers, Chairman of the Fire Protection Subcommittee, stated that the purpose of this session was to discuss the proposed Draft Regulatory Guide on the fire protection program for permanently shutdown and decommissioning nuclear plants.
On July 29, 1996, the NRC amended its regulations on the decommissioning of nuclear power reactors by amending Part 50,
" Domestic Licensing of Production and Utilization Facilities,"
of Title 10 of the Code of Federal Regulations (CFR). These changes included in the amendment to 10 CFR 50.48, " Fire Protection," which added paragraph 50.48(f). Paragraph 50.4 8 (f) refers to licensees that have submitted the necessary certifications required by the amended 10 CFR 50.82, "Termina-tion of License." Paragraph 50.48(f) requires that the licensee of a permanently shut down nuclear power plant maintain a fire protection program to address the potential for fires that could result in the release or spread of radioactive materials. This proposed draft regulatory guide is to provide guidance to licensees for maintaining fire protection programs for nuclear plants that are permanently shut down and defueled and are in the process of being decommissioned. Such guidance has not heretofore been available.
The staff stated that a licensee may develop a performance-based fire protection program to meet the requirements of 10 CFR 50.4 8 (f) . The performance goals and measures established by the licensee should be based on established industry standards and practices and should provide reasonable assur-ance that the fire objectives of 10 CFR 50.48 will be met.
Conclusion The Committee issued a letter to the Executive Director for Operations, dated September 10, 1997, on this matter. j i

IV. PROPOSED GENERIC LETTER AND REGULATORY GUIDE ASSOCIATED WITH STEAM GENERATOR INTEGRITY (Open)
[ Note: Mr. Noel Dudley was the Designated Federal Official for this portion of the meeting.]
Introduction Dr. Seale, Acting Chairman of the Materials and Metallurgy subcommittee, noted that there is a long history related to the proposed generic letter and draft regulatory guide regarding steam generator tube integrity. He noted that during a recent meeting of the Subcommittees on Materials and Metallurgy and on Severe Accidents, the staff announced a revised approach to ensuring steam generator tube integrity.
This alleviated the need for rulemaking. He stated that there are still several unresolved issues, such as what constitutes a viable regulatory policy with regard to steam generator tube integrity and the relative rigidity of proposed technical specifications.
Staff Presentation Mr. Jack Strosnider, NRR, noted that during the June 12, 1997 ACRS full Committee meeting, the staff presentcd the results of the risk assessment and regulatory analysis, which the staff had developed in support of the proposed rulemaking regarding steam generator tube integrity. He explained that subsequently, in accordance with the directions in a June 30, 1997 SRM, the staff prepared a proposed generic letter that:
a requested licensees to modify technical specifications to address inspection requirements, condition monitoring, and operational assessment; e provided licensees the option for proposing new repair criteria; and
o 444th ACRS Meeting 7 September 3-5, 1997
- - provided model technical specifications. I Mr. Strosnider provided details -of the model technical specifications, which are perfomance-based and focused on the condition of steam generator tubing at the end of the operat-ing cycle. He outlined Draft Regulatory Guide DG-1074, " Steam Generator Tube Integrity," that provides guidance on quantification of inspection methods, perfomance of condition monitoring, and operation assessments. He noted that' the staff plans to brief the ACRS on the resolution of a Differing Professional Opinion and the development of a Draft Regulatory Guide regarding risk guidance: DG-1073, "An Approach to Plant-Specific, Risk-Informed Decision Making: Induced Steam Generator Tube Rupture," when these documents are completed.
Mr. Timothy. Reed, NRR, provided the following responses to issues that had been raised at previous ACRS meetings:
- the use of a safety factor of 3 is correct, e exceeding the operationel leakage performance criteria will not automatically result in enforcement actions,
- defense-in-depth is an attribute of a compliance-based approach and is not a component of - a regulatory risk approach, and
- sufficient guidance exists in the steam generator tube Draft Regulatory Guide for licensees to develop processes to meet the performance criteria.
Mr. Reed stated that many of the issues identified by the ACRS were associated with risk assessments and would be addressed in DG-1073.
The ACRS Members and the staff discussed the relationships among the different documents associated with steam generator integrity, the schedule for completing DG-1073, ind'astry
444th ACRS Meeting 8 September 3-5, 1997 4
involvement in developing the requirements and guidelines, the adequacy of the proposed regulatory structure, and the flexibility provided by the model technical specifications.
Nuclear Enercrv Institute Presentation Mr. Clive Callaway, Nuclear Energy Institute (NEI), stated that he could not constructively contribute to the discussion since neither the proposed generic letter nor DG-1074 were available for industry review. He described the guideline documents that the Electric Power Research Institute (EPRI),
NEI, and the PWR Owners Groups have developed in the areas of nondestructive examination, condition monitoring, and operat-ing experience. He suggested that, based on the industry guidelines, the staff could monitor licensee programs using tube integrity performance criteria. Mr. Callaway stated that there is a need for NEI to meet with the staff to better understand its approach and schedule, and to identify differ-ences between the NRC regulatory guides and the industry guidance documents.
The ACRS Members and Mr. Callaway discussed the existing industry guidelines and the exchange of information between the staff and NEI. Dr. Seale encouraged NEI, as a major stakeholder, to take full advantage of the public comment period for the proposed generic letter.
Conclusion The ACRS issued a report to Chairman Jackson, dated September 15, 1997, on this matter.
V. REPORTING RELIABILITY AND AVAILABILITY INFORMATION FOR RISK-SIGNIFICANT SYSTEMS AND EOUIPMENT (Open)
[ Note: Mr. Michael T. Markley was the Designated Federal Official for this portion of the meeting.)
. i
, 444th ACRS Meeting 9 September 3-5, 1997 Intreduction Dr. Apostolakis, Chairman of the ACRS Subcommittee on Proba-bilistic Risk Assessment (PRA) introduced the topic to the Committee. He noted that the joint Subcommittees on PRA, Plant Operations, and Fire Protection had met with representa-tives of the NRC staff and of the industry to discuss these matters on August 28, 1997. He stated that AEOD had provided documents related to the NRC control of proprietary materials.
He added that these documents govern the public availability of information provided to the staff by INPO.
NRC Staff Presentation Mr. Steve Mays, AEOD, provided a brief presentation to the Committee. He' summarized the agreements between the NRC and INPO for sharing reliability and availability information provided by INPO. member utilities. He also discussed the regulatory requirements for controlling proprietary informa-tion and limits for sharing this information with the public.
Significant points made during the discussion include:
- 10 CFR Section 2.790 (a) (4) provides for mandatory disclosure of agency documents, with some exceptions, including confidential commercial or proprietary materi-als.
The NRC has established written agreements with INPO that acknowledge the proprietary nature of plant reliability and availability data.
Plant-specific INPO data can be released to the public if the information is the basis for a regulatory decision such as an individual licensing action.
Generic analyses of INPO data can be released where individual plants are not identified.
+
444th ACRS Meeting 10 i September 3-5, 1997 _l
- - Equipment Performance and Information Exchange will be controlled under the same format and requirements as the
-earlier Nuclear Plant Reliability Data System (NPRDS).
Dr. Powers reiterated his concerns from the August 28, 1997 joint Subcommittee meeting, regarding the availability of " raw 1 INPO data" for public scrutiny and evaluation. Drs. Seale and l Fontana also questioned the practice of controlling this information when it is the basis for governmental action or
' decisions.- Dr. Kress questioned the prudence of the staff entering into agreements where the availability of information l to the public is constrained. The staff stated that the i agreement with INPO was essentially the same as that which l controlled access to NPRDS data. Mr. Mays also stated that !
these agreements exist to protect the financial interests of l sponsoring organizations such as those for thermal-hydraulic computer code development.
l At the conclusion of the meeting, Dr. Apostolakis stated that the Committee expects to prepare a report to'the Commission regarding this matter. ,
conclusion The Committee provided a report to Chairman Jackson dated September 11, 1997, on this matter.
VI. NRC PROGRAMS FOR RISK-BASED ANALYSIS OF REACTOR OPERATING EXPERIENCE AND SPECIAL STUDIES (Open)
(Note: Mr. Amarjit Singh was the Designated Federal Official for this portion of the meeting.)
Introduction Dr. Apostolakis, Chairman of the Probabilistic Risk Assessment Subcommittee, stated that the purpose of this session was to hear a briefing by representatives of the NRC staff regarding
444th ACRS Meeting 11 September 3-5, 1997 the NRC programs for risk-based analysis of reactor operating experience as well as the results of several special studies performed by the staff, including those related to auxiliary feedwater, Westinghouse reactor protection systems, loss of offsite power, initiating events, reactor core injection cooling, high pressure core injection, and fire events.
NRC Staff Presentation The staff briefed the Committee regarding the accident sequence precursor (ASP) program. The ASP program was originally a research project developed by RES. The responsi-bilities were later transferred to AEOD. This program is now a specific task action in the PRA Implementation Plan where AEOD conducts and manages the ASP program. During the August 29, 1997 Subcommittee meeting, representatives from RES discussed their efforts to support AEOD through ASP model development.
Conclusion This session was information only and no Committee action was required.
VII. SITE-SPECIFIC SAFETY GOATA (Open)
(Note: Mr. Noel Dudley was the Designated Federal Official for this portion of the meeting.)
Dr. Thomas Kress, Chairman of the Safety, Technology, and Criteria subcommittee, led a discussion concerning the development of site-specific large, early release frequency (LERF) criteria for nuclear plants. He explained that Mr.
Richard Sherry, Jt CRS Senior Fellow, had helped to develop a methodology for calculating site-specific LERF criteria from the individual early fatality quantitative health objective (QHO). The methodology was sent out to three national laboratories for peer review.
}
'l, '
I 444th ACRS Meeting 12 September 3-5, 1997 Dr. Kress explained that the site-to-site variability of the site-specific LERF values, compared to the uncertainties associated with the methodology, were small enough so that site-specific LERF criteria were not necessary. He noted that I based on the methodology results, total early fatality risk or societal risk, which is strongly effected by the population density near nuclear plants, should be considered as a metric l for making regulatory decisions. I i
Dr. Kress read a draft ACRS report on this subject. Dr. l Powers raised the issue of the uncertainties associated with the radionuclide dispersion model used in the methodology.
The ACRS Members and the staff discussed the relationship between population density and societal risk, the historical debates regarding societal risk, the difficulty in redefining a QHO, and the consequences of having plants operating outside a newly defined safety goal. l Conclusion The ACRS issued a report to Chairman Jackson, dated September 19, 1997, on this matter.
VIII.USE OF UNCERTAINTY VERSUS POINT VALUES IN THE PRA-RELATED DECISIONMAKING PROCESS (Open)
[ Note: Mr. Michael T. Markley was the Designated Federal Official for this portion of the meeting.)
Dr. Apostolakis, Chairman of the ACRS Subcommittee on PRA, provided a report of the meeting of the joint Subcommittees on PRA, Plant Operations, and Fire Protection regarding the use of uncertainty versus point values in the PRA-related decisionmaking process. He noted that joint Subcommittees had met with representatives of the NRC staff and of the industry on August 28-29, 1997, to discuss these matters. He stated that the Commission had approved the Committee and staff's
. 444th ACRS Meeting 13 September 3-5, 1997 request for an extension in responding to the SRM dated May 27, 1997.
Dr. Apostolakis noted that the staff had conducted a workshop to solicit industry and public feedback on the draft Standard Review Plan (SRP) and associated guidance for risk-informed, performance-based regulation. He summarized a few points raised by participants at the workshop including completeness of PRAs and implications for risk-informed changes to the current licensing basis, types of uncertainty and approaches for addressing them, concern that acceptance criteria would be implemented as limits, and concern over the implications for plants that already exceed the Commission's Safety Goals. He also noted that Dr. Harry Martz of Los Alamos National Laboratory had given a presentation on the consideration of uncertainty in the application of Safety Goals.
NRC Staff Presentation Mr. Thomas King, Office of Nuclear Regulatory Research (RES),
led the discussions for the NRC staff. Messrs. Mark Cunningham, RES, .nd Gareth Parry, NRR, provided supporting discussion. The staff summarized key considerations in the treatment of uncertainty, guidelines for assessing complete-ness, and the schedule for completion of the SRP and associ-ated guidance for risk-informed, performance-based regulation.
Significant points made during the discussion include:
The state of the art in risk analysis has uncertainty (completeness, model, and parameter), variability in analysis assumptions, and quantifiable and unquantifiable uncertainty.
Acceptance guidelines and definitions of change have inherent difficulties in numerical values and decision guidelines, direction and magnitude of change, and bundling of proposed changes.
i', .,',.
. 444th ACRS Meeting.
14 September 3-5, 1997 The staff philosophy for addressing uncertainty is presented in Draft Regulatory Guide DG-1061 (General Guidance) including the use of mean values, use of sensitivity ' analysis and qualitative arguments, and qualitative or bounding analysis to address completeness.
- Meetings with the'ACRS Subcommittee on PRA are scheduled for October 21-22 and November 13-14, 1997, to address potential policy issues and the proposed final.SRP and associated guidance.
Dr. Apostolakis expressed the view that the Commission may have considered the. issue of completeness and uncertainty in establishing its Safety Goals.- Drs. Kress and Powers stated that there was still a need for assessment of the risks for other modes of operation. (e .g. , low-power and shutdown operations). Dr. Apostolakis stated that requiring quantifi-cation of uncertainty analysis may unnecessarily limit risk-informed initiatives. He suggested that trore consideration be given to unquantifiable benefits of proposed changes.
Ennelusion The Committee expects to provide a report to the Commission l during a future meeting.
IX. MFFTING WITH THE NRC FYFCUTIVE DIRECTOR FOR OPERATIONE (Open)
[ Note: Dr. M. El-Zeftawy was the Designated Federal Official for this portion of the meeting.)
Dr. Seale welcomed Mr. L. Joseph Callan, Executive Director for Operations, and his staff. Dr. Seale stated ACRS appreci-ation for the willingness and cooperation of Mr. Callan and his staff to discuss with the Committee items of mutual interest.
I

, 444th ACRS Meeting 15 September 3-5, 1997 Mr. Callan noted that he received a memorandum from the ACRS Executive Director indicating six items of interest to the ;
committee. The Committee, however, chose to discuss only three items. These were the Senior Management Meeting (SMM) process, NRC oversight of Department of Energy (DOE) nuclear facilities, and NRC Research Program activities.
Mr. Callan stated that the SMM is an important part of l
the NRC process for evaluating licansee performance.
Decisions regarding the appropriate level of regulatory attention to plants exhibiting performance problems are made at the semiannual SMM. Throughout the process, the information regarding the performance of the plants is provided primarily by the regions and NRR. The AEOD ;
staff also provides independent insights based on the NRC l Performance Indicators. The Office of Enforcement (OE) and the Office of Investigations (OI) provide additional insights. The SMM process is described in detail in SECY-96-093 anti in Management Directives 8.13 and 8.14.
In an SRM dcted June 28, 1996, the Commission directed the staff to assess the SMM process and evaluate the 1 development of indicators that can provide a basis for l judging whether a plant should be placed on or deleted j from the watch list. In response to this SRM, a study was perfomed with the assistance of a contractor (Arthur Andersen) and a report was issued on December 30, 1996.
The Arthur Andersen report addressed two major areas:
the SMM information base and the SMM process. The first ;
area involves the inputs to the SMM decision process, including performance indicators and the criteria used by NRC senior managers. The second area involves the roles of SMM participants, the method of reaching consensus, the presentation of information, and the documentation of meeting results. Based on the Andersen study and the staff's independent evaluation, a set of nine recommenda-tions and actions were proposed. These are:
A 444th ACRS Meeting 16 September 3-5, 1997 Assess leading indicators, such as management and operational effectiveness on an ongoing basis.-
Re-engineer assessment.information to better sup-port the SMM decisionmaking process.
- Shift from use of subjective to objective factors.
Restrict format and volume of information provided to senior managers for the SMM.
Initiate continued ' effort to improve information access through automation.
- Attain a better balance in SMM participant's roles in the decision process and include consideration of consensus decisionmaking techniques.
- Present information in a rigorous and structured manner.
- Develop a better process for completing the public record of SMM meetings.
Mr. Callan noted that the Arthur Andersen report is only a starting effort and the staff is continuing to work on SMM implementation. AEOD issued a memorandum that provides guidance on the implementation of the above recommendation, including a corresponding milestone schedule. By June 1998, the majority of the recommenda-tions are scheduled to be implemented.
- Mr. Hugh Thompson,Jr. , Deputy Executive Director for Regulatory Programs, described the status of NRC over -
sight of DOE nuclear facilities. He noted that the NRC
444th ACRS Meeting 17 September 3-5, 1997 position regarding the regulation of nuclear safety, safeguards, security, and radiation protection at DOE facilities requires careful consideration. Among the issues to be considered are the magnitude of the poten-tial workload, the types of DOE facilities and opera-tions, NRC's current statutorf authority, overlapping regulatory authority with other Federal agencies, and NRC's funding requirements and the mechanism that could 1
be employed to recover the cost of its oversight.
]
Direction Setting Issue #2 addressed options for NRC's position on the regulation of DOE facilities. In March 1997, after considering public comments, as well as the December 1996 DOE decision to seek transfer of oversight to NRC, the Commission endorsed seeking the transfer to NRC of responsibility for the regulatory oversight of l
certain DOE nuclear facilities, contingent on adequate l funding, staffing, and a clear delineation of the authority NRC would exercise over these facilities. In addition, the Commission directed the staff to convene a high-level NRC Task Force to identify, in conjunction with DOE, the policy and regulatory issues needing analysis and resolution. In June 1997, both DOE Secretary Pefia and NRC Chairman Jackson agreed to pursue J NRC regulation of DOE nuclear facilities, on a pilot program basis.
- In FY 1998, the Task Force plans to conduct a pilot program of simulated regulation at three facilities. These are Lawrence Berkeley National Laboratory, the Spent Fuel Dry Transfer and Storage Facility (Idaho), and the Radiochemical Engineering Development Center (Tennessee). In FY 1999, additional pilot facilities of a different nature will be added.
- Mr. Ashok Thadani, Deputy Executive Director for Regula-tory Effectiveness, stated that one of the general objectives of the NRC Strategic Plan is to " supply research needed to regulate effectively." The supporting strategy for accomplishing this objective states that the
1

l these criteria, which are embedded in a methodology for !
assessing where core research capabilities will be needed in the foreseeable future, and to determine their size and composition.
In an SRM dated March 28, 1997, the Commission'Anstructed j the staff to develop and submit-to-the Commission a plan for implementing the Commiesion's-decision that "...the preparation and coordination of rulemaking should move from RES to the Program Offices, and that most confirma-tory research activities now in the Program Offices should move to RES." In addition, the Commission noted in the SRM that there are many-key questions raised in DSI #22, and the staff should provide an integrated set of recommendations for Commission consideration. In order to respond to the SRM, the Directors of NRR, NMSS, AEOD, and RES have formed an ad hoc steering group. The steering group noted that, of the.202 issues identified by the Strategic Assessment and Rebaselining Steering Committee, the issue of the future role, scope, and organization of NRC's generic issues program remains an open issue, the resolution of which also affects the role and function of RES. Hence, it would seem appropriate to pursue resolution of these issues simultaneously.
Mr. Thadani noted that the agency needs to stay abreast of national 'and international nuclear safety develop-L ments, emerging technologies, and design concepts.
l In conclusion, Dr. Seale thanked Messrs. ' Callan, Thompson, and Thadani, and the NRC staff regarding the information provided to the Committee, and invited Mr. Callan and his staff to a l-

X. BWR PRESSURE VESSEL SHELL WELD INSPECTIONS (Open)
-[ Note: Mr. Amarjit Singh was the designated Federal Official for this portion of the meeting.)
Introduction Dr. seale, Acting Chairman of the Materials and Metallurgy and Severe Accidents Subcommittees, stated that the purpose of this session was to hear presentations by representatives of the NRC staff regarding the interim Safety Evaluation Report on a report, "BWR Vessel and Internals Project, BWR Reactor Pressure Vessel Shell Weld Inspection Recommendations (BWRVIP-05)," submitted by on the Boiling Water Reactor Vessel and Internals Project (BWRVIP). -
NRC Staff Presentatlon The NRC staff provided the background and the results of its independent assessment of the BWRVIP-05 report, The staff performed an independent assessment of the BWRVIP-05 report. i The staff concluded that the BWRVIP-05 report did not include l a risk-informed analysis, nor did it adequately consider beyond design basis transients, which appear to dominate the estimated frequency of BWR reactor vessel failures. On the basis of the independent assessment of the BWRVIP-05 report, the. staff also concluded that any significant reactor pressure vessel vulnerability to failure would not be expected until relatively late in the life of the reactor vessel, when higher j levels of embrittlement are reached. Based on this conclu- !
i i

e 444th ACRS Meeting 20 l September 3-5, 1997 i
sion, the staff will consider plant-specific requests, if technically justified, to delay inspections of the circumfer-ential welds for up to 40 months. I i
The staff is expected to complete its review of the BWRVIP-05 report and issue a final Safety Evaluation Report by December 1997, concluJion l
The Committee issued a letter to the Executive Director for Operations, dated September 10, 1997, on this matter.
XI. SUBCOMMITTEE REPORT (Open)
[Notm : Mr. Paul A. Boehnert was the' Designated Federal Official for this portion of the meeting.)
i The Chairman of the Thermal-Hydraulic Phenomena Subcommittes '
provided a report on the meeting that was held to continue its review of the Westinghouse Test and Analysis Program being conducted in support of the AP600 design certification. The Subcommittee reviewed the modifications made to the H NOTRUMP small-break loss-of-coolant accident (LOCA) code to support its use for AP600 evaluation model analyses. The Subcommittee concluded that Westinghouse needs to address the following issues:
- A number of specific items need to be examined to ensure that the code meets the requirements stipulated in Appendix K to 10 CFR 50.46.
The documentation associated with the AP600 version of NOTRUMP requires improvement.
- A stronger tie needs to be demonstrated between the Phenomena Identification and Ranking Table and verifica-
444th ACRS Meeting 21 September 3-5, 1997 tion and validation testing to show that the tests have appropriately covered the ranges of important phenomena.
A proposed fix to the code (taking an initial arbitrary
- penalty" in the in-containment refueling water storage tank. level) to compensate for poor performance on drain flow from the pressurizer needs to be justified with regard to its meeting the intent of Appendix K.
Conclusion The Subcommittee will hold a follow-on meeting to address these issues.
XII. SUBCOMMITTEE REPORT (Open)
[ Note: Dr. M. El-Zeftawy was the Designated Federal Official for this portion of the meeting.)
Dr. Kress, Chairman of the Regulatory Policies and Practices subcommittee, provided a report to the full Committee regard-ing a meeting on August 27, 1997. The purpose of the Subcom-mittee meeting was to explore the subject of defense-in-depth.
The Subcommittee discussed the formal definition of defense-in-depth, how it has been used historically and if there is a need for a new policy statement, and if necessary and suffi-ciency limits could be established.
Dr. Kress summarized the main points of the Subcommittee discussion as follows:
- Defense-in-depth (DID) historically has been defined mostly by example and is generally unclear.
- DID is a philosophy and not a requirement.
- DID is structurally scattered throughout the body of the regulations, and thus, the necessary and sufficiency
'. . . ~
'444th ACRS Meeting 22 September 3-5, 1997 (N&S) limits are already set by the existing regulations.
PRA is a tool that measures the effectiveness of imple-mentation of the DID philosophy.
A new policy statement on DID is probably not needed.
If a new policy statement is to be developed, it should be part of a new policy on PRA and Safety Goals.
DID can be defined in terms of three " levels:" preven-tion, mitigation, and emergency response.
- It seems impractical to establish N&S limits for levels 1 and 3, because the requirements for these are perfor-mance in nature.
It would be useful to develop technical risk-based NES lim 3ts for level 2 requirements. The most important need is to establish the appropriate regulatory balance between core damage frequency and conditional containment failure probability.
Conclusion The Subcommittee concluded that the experience that will be gained in the near future by implementing the defense-in-depth portions of the risk-informed decision process on requested changes to the licenses basis should be very useful. It might be reasonable to await this experience before developing any policy statement. i XIII. PROPOSED RULE ON SHUTDOWN AND FUEL STORAGE POOL OPERATIONS (open)
[ Note: Dr. M. El-Zeftawy was the Designated Federal Official for this portion of the meeting.]
l
f '444th ACRS Meeting 23
. September- 3-5,-1997 Introduction Dr. Powers stated that the NRC is proposing to amend its regulations regarding.the Shutdown Rule. On April 18,1997, the ' ACRS; issued its report to the Commission expressing concerns regarding the existing understanding of risk during shutdown operations. The staff sees a need for an enforceable rule to ensure safety during shutdown operations.
NRC Staff Presentation Mr. Eric Weiss, NRR, stated that the objective of the propci..ad rule is t.o establish a clear regulatory framework for ensuring that cold shutdown, refueling outages, and fuel pool opera-tions continue to be conducted in a safe manner. To accom-plish the objective for fuel pool operations, licensees would be required to document factors important to safety in their Final Safety Analysis Report and incorporate these factors'in fuel pool operating procedures.
The proposed rule consists of three parts: Shutdown Opera-tions, Fire Protection,-and Spent Fuel Pool Operations. The proposed rule also allows licensees to enhance' operational flexibility by . the use of PRA methods as a complement to traditionel analyses.
The Shutdown Operation section of the proposed rule was structured with the objectives of reducing the frequency of events that can lead to loss of the decay heat removal function, assuring that mitigative equipment is available for those events that do occur, providing a measure of performance
~
through monitoring of parameters that represent necessary I safety functions, and facilitating inspection and enforcement l activities. These goals are to be achieved through'a combina-tion of procedural, monitoring, and mitigation capability requirements.
l l
l
444th ACRS Meeting 24 September 3-5, 1997 The Fire Protection section is intended to extend the fire protection provisions already provided during power operation to shutdown operation. The proposed rule would require licensees to implement measures to minimize the frequency of fires during shutdown operations. It would also require that the decay heat removal function be maintained free of fire damage, or that fire damage be limited by promptly detecting.
controlling, and extinguishing fires that do occur.
)
l The Fuel Storage Pool Operhtions section is intended to establish clearly defined regulatory controls for current ;
operational practices in spent fuel pool operations and to facilitate inspection and enforcement.
In support of the shutdown operation requirements of 10 CFR Section 50.67, conforming changes would have to be made to other regulations. The most significant of these are:
Adding the structures, systems, and components necessary for compliance with the shutdown operation requirements of Section 50.67 to the Maintenance Rule (Section 50.65) and the License Renewal Rule (10 CFR Part 54),
- Providing for notification and submitting reports to the NRC in accordance with Section 50.72 and Section 50.73, of any event that results in actuation of the mitigation j equipment, and
- Adding a definition of shutdown operations to Section 50.2 which makes it clear that normal operation includes shutdown operation.
I Nuclear Enerev Institute Presentation j Mr. Anthony Pietrangelo stated that the Nuclear Energy ,
Industry (NEI) is concerned that the proposed rule will not I raise the current level of safety, yet will conservatively l cost the industry an estimated $200 million to implement. In
1 444th ACRS Meeting 25 September 3-5, 1997 addition, the proposed rule overlooks the regulatory oversight and safety benefits provided by 10 CFR 50.65, the Maintenance Rule.- The implementation burden associated with the proposed rule would only increase economic pressure and divert licensee attention from outage . management to regulatory compliance without an attendant benefit in safety.
Mr. Pietrangelo noted that since 1991, when the industry developed and implemented' NUMARC 91-06, Guidelines for Industry Actions to Assecs Shutdown Management, there has been a significant decrease in both the frequency and severity of events during shutdown. In addition to the substantial improvement in safety, there has been an equally impressive productivity improvement resulting in a 40% reduction in the median refueling outage duration. Therefore, it is in the industry's self interest to continue the practices that have been successful in achieving safer, shorter outages.
The industry believes that the Maintenance Rule and other existing regulations adequately address NRC concerns over the potential for licensees to withdraw from current practice, and that a separate shutdown rule is unnecessary. In addition, the industry and the NRC have worked for several years to develop a practical model to demonstrate risk-informed, performance-based regulation through the maintenance rule. As such, the maintenance rule provides a regulatory framework that encompasses both shutdown and power operations. The potential for achieving a more consistent and cohesive risk-informed, performance-based regulatory framework cannot be realized if overlapping and inconsistent requirements are added that impose regulatory burden without improving safety..
conclusion The Committee issued a report to Chairman Jackson, dated September 10,'1997, on this matter. It recommended that the proposed rule not be issued for public comment. The Committee recommended that the NRC satff explore other methods and work L
I 444th ACRS Meeting 26 l
September 3-5, 1997 j I
with the industry to find ways to achieve enforceability without penalizing industry practices. The Committee also recommended that fuel storage pool operatione and fire protection requirements for shutdown operations not be included in the proposed rule.
XIV. IMPROPER CONTROL ROD MOVEMENT DURING SHUTDOWN AT ZION UNIT 1. j AND NONCONSERVATIVE OPERATIONS DURING ISOLATION OF RECIRCULA-TION PUMP SEAL TRAK AT CLINTON (Open)
[ Note: Mr. Michael T. Markley was the Designated Federal Official for this portion of the meeting.)
Introduction Mr. Barton, Chairman of the ACRS Subcommittee on Plant Operations, introduced the topic to the Committee. He briefly summarized the operating events at Zion Unit 1 and Clinton.
He noted that the ACRS had requested the staff presentation to focus on the human and organizational performance issues. He also noted that licensee representatives from each utility were in attendance and would be willing to answer questions as ,
needed. Mr. Barton introduced cognizant NRC representatives I in attendance.
NRC Staff Presentation Mr. Robert Dennig, NRR, introduced the presenters from the NRC staff. Mr. Marc Dapas, Region III, presented the findings of-the Augmented Inspection Team (AIT) for the event at Zion. l Mr. Geoffrey Wright, Region III, presented the findings of the Special Inspection Team (SIT) at Clinton. Mr. Greg Galletti, NRR, discussed the human factors aspects of the Clinton and ,
Zion events. Mr. Jay Persensky, RES, provided supporting l discussion regarding human performance modeling and methodolo- :
gies.
444th ACRS Meeting 27 September 3-5, 1997 Mr. Dapas reviewed the sequence of events for the Zion incident and summarized the findings of the AIT assessment.
He noted that on February 21, 1997, a control room operator improperly inserted control rods too far into the core, taking the reactor suberitical. The operator continuously withdrew rods to restart the reactor without direction from shift management. At the onset of this incident, the plant was approaching the end of allowed outage time (AOT) for a containment spray pump (CS) pump that was out of service (inoperable with maintenance ongoing) and operators had commenced a controlled shutdown of the unit. Operating shift l management w.s focused on restoring the CS pump and there were l approximately 39 people in the control room envelope including senior station management. Significant points made during the discussion include:
i Operations supervision did ne maintain a proper level of ;
oversight to ensure that operating shift activities were l conducted in a controlled manner.
Direction was not provided to operations supervision to correct command and control deficiencies, communications problems, lack of teamwork, and control room distrac-tions. l Actions of the nuclear station operator reflected a lack of understanding of reactor physics and of proper control rod manipulations for approach to criticality.
- The significance of the event was not communicated to management in a timely manner. Operations management returning of the operating shift to licensed duties reflected a lack of appreciation for the significance of the event.
- The operating shift was newly formed and the licensed operator requalification program was deficient in
444th ACRS Meeting 28
' September 3-5, 1997 assessing shift capability in conducting the shut-down/ prompt restart evolution.
- The - Zion event did not pose a risk to the health and safety v2 the public. However, the event revealed significant w fety insights regarding human performance.
Mr. Wright reviewed the sequence of events for the Clinton incident'and summarized the findings of.the SIT assessment. ,
He noted that on September 5, 1996,. operators at Clinton were attempting to place the unit in single-loop operation by isolating the . "B" reactor recirculation pump (RRP-B)- At the time, the licensee believed the seal package for RRP-B was the source of unidentified reactor coolant leakage. Ineffective-planning resulted in operators taking nonconservative action to isolate the seal flow to RRP-B. The seal failed and the leak rate increased from about 5 gpm-to approximately 38 gpm.
Significant points made during the discussion include:
- Inappropriate operator action resulted in the failure of the "B" reactor recirculation pump seal and extended shutdown of the unit.
Management failed to put economic expectations in proper i perspective with safety. Emphasis had been placed on !
maintaining power production in attaining single loop operations.
Operator actions reflected an attitude of procedural ,
compliance through intent rather than adherence to actions defined in procedures.
i Mr. Galletti discussed the human factors analysis framework, noted the significant findings of the inspection teams, and reviewed the actions relative to each of the findings.
Significant points made during the discussion include:
s .
j 444th ACRS Meeting 29 September 3-5, 1997 The Clinton incident did not have the same command and control issues observed at Zion. However, management tolerance for. procedural deviations and a lack of sensitivity to removing performance barriers.was evident at Clinton but not at~ Zion. Also, Clinton'had longer-term problems with effectiveness of past corrective actions.
- - Both incidents provide valuable input for the NRC's Human Performance and Human Reliability Implementation Plan -
including information for the HFIS database and Senior Management Meeting (SMM) .
- The staff plans to use the ATHEANA model to assess human performance.
Dr. Apostolakis questioned how proper control room communica-tions are defined. The staff stated that the protocol is an announcement of planned actions by the reactor operator, a repeat-back acknowledgement by the cognizant shift supervisor or senior reactor operator that the message is understood, and.
an announcement by the operator when the subject' action is being taken.
Mr.. Barton stated that fundamental operator knowledge of reactivity changes is an industry-wide problem, He added that most operator training programs are symptom-based and that this training focuses on transients rathur than reactivity control. Mr. Barton also questioned operating shift composi-tion at Zion. In particular, he questioned -why the subject operating crew had not worked together before or trained as a working unit. The licensee stated that this crew was formed as a sixth operating shif t (from five existing shifts) to support outage activities.
Dr. Seale questioned when the human performance assessment--
would move more toward PRA. The staff stated that the ATHEANA
1 l
444th ACRS Meeting 30 l September 3-5, 1997 model would be used and the Seabrook Nuclear Plant was participating as a pilot plant.
l l
At the conclusion of the meeting, Mr. Barton thanked the i participants and stated that he was not recommending the l Committee to prepare a letter or report regarding these matters.
l Conclusion This briefing was for information only. No Committee action was required. i XV. EXECUTIVE SESSION (Open) l
