l l l ENCLOSURE 2 l l Summary of Issues Discussed During the July 20 - 21,1999, Region IV Risk Information f Counterpart Workshop 1. Industry /NRC interface issues related to the use of risk information The Region IV ser.ior reactor analysts (SRAs) provided a recap and perspective of NRC initiatives and activities accomplished during the previous year. Communication of risk information and quantitative analyses between NRC Region IV and Region IV licensees was effective. Challenges were identified in the area of more timely exchange of information relative to notices of enforcement discretion (NOED) requests and risk significant maintenance activities. 2. Use of risk information at the National Aeronautics and Space Administration (NASA) A contractor representative from NASA provided an overview of the development and use of PRA technology in the space shuttle program. Information on the development of computer codes and modeling approaches were shared with the meeting participants. I l Where possible, analogies between the NASA and nuclear industry approaches were identified. 4 3. Use of risk information in prioritizing engineering work A representative from the Nebraska Public Power District provided an overview of the i use of PRA technology in prioritizing engineering activities at Cooper Nuclear Station. The discussion centered around which engineering activities are most amenable to risk prioritization and the limitations of the use of PRA technology in this type of application. 4. Changes to 10 CFR 50.65, the " Maintenance Rule" Representatives from the Office of Nuclear Reactor Regulation (NRR) provided a summary of the status of the Maintenance Rule and the schedule for implementation of the upcoming rule change. The discussions involved the development of the new regulatory guidance and the upcoming revision to NUMARC 93-01. The NRR representatives also provided an overview of recent discussions with the Nuclear Energy i institute (NEI). S. NRR perspective on risk informed activities The Director, Division of Systems Safety and Analysis, of NRR provided an overview of l risk informed activities from a program office perspective. The presentation stimulated a i discussion of the NRC's approach to uses of risk information, including approaches to l revising the requirements of 10 CFR part 50. Additionally, a perspective on the quantitative thresholds associated with risk significance was provided. t ( l I 1 it _

2 6. Fire risk analysis Representatives from NRR provided a presentation on the proposed methodology for assessing the risk of fire protectior, findings. The discussion included an overview of the i methodology as well as a specific example to illustrate the process. 7. Roundtable discussions Representatives from the NRC and the industry conducted roundtable discussions to explore issues of mutualinterest. Of particular interest were the discussions involving the status of the industry effort to certify PRA models, methods and approaches associated with shutdown risk, use of risk information in licensee event reports, the significance determination process (SDP) associated with the new oversight and assessment process, and general NRC/ industry interface issues. 8. Risk informed changes to the inspection and assessment process A representative from NRR provided an overview of the NRC's new oversight and assessment process. Emphasis was placed on the pilot plant activities, and in particular, the SDP. Several specific case studies were provided to illustrate how the new process is designed to operate. 9. Combustion Engineering Owners Group (CEOG) initiatives An industry representative provided an overview of CEOG activities from a risk perspective. The discussion involved specific examples of technical specification allowed outage time extensions and other specific exemptions from the regulations being requested by CE licensees. 10. Temporary changes and transition risk A representative from Southern Califomia Edison's San Onofre Nuclear Generating Station provided information related to the risk implications of temporary plant changes and transition risk. The discussion involved issues related to the appropriateness of modifying various assumptions and success criteria as well as overall methodological considerations. Several specific results were quoted as case studies. The ensuing discussions involved the implications of these types of results in future NOEDs. 11. Methods of shutdown risk assessment A representative from Entergy's River Bend Station (RBS) provided an overview of the methods of shutdown risk assessment. The discussion was centered around RBS's approach to modeling shutdown risk. Insights we're provided as to the overall results of the RBS shutdown PRA as well as contributors to shutdown risk. I

, 12. NRC Feedback on Specific issues of Concern During the course of the workshop, participants requested feedback on the following three issues: a. Can facilities other than the pilot plants provide feedback to the NRC regarding the new oversight and assessment process? Yes. All facilities are encouraged to become familiar with ar d provide feedback on the new oversight and assessment process. Currently, the existing process of " regulatory feedback" via NRC management site visits is the process to be used. However, a Federal Register Notice will be published, which will describe the new process and will solicit public (and industry) feedback. b. . What are the NRC's plans to revise the SDP to make it more plant-specific? During the current pilot process, the published risk studies (i.e., Individual Plant Examinations (IPEs)) are being reviewed to develop plant-specific sequences to be used in the SDP. These sequences are then further reviewed by NRC risk analysts in cooperation with representatives from the pilot plants in order to ensure their accuracy. At the end of the pilot plant phase of the new oversight process, the NRC will review the results of these efforts to determine the most effective and efficient approach to apply to the remainder of the plants. c. Does the new requirement to assess the risk of maintenance activities in 10 CFR 50.65 a(4) apply to activities such as building scaffolding in the turbine building? Yes, to the extent that such activities have an impact on plant risk. The requirement to assess the risk of maintenance activities is intended to envelope those plant activities that may adversely affect the probability of an initiating event and/or the availability or reliability of mitigating systems. Therefore, to the extent that building scaffolding fulfills one of these considerations, it should be considered. The NRC is developing a revised Regulatory Guide which will provide more definitive guidance on the changes to the Maintenance Rule. ) 2

WORKSHEET FOR REACTOR AND PLANT SYSTEM DEGRADED CONDITIONS Referance/ Title (LER #, inspection Report #, etc): BWR Example No. 4 Factual Description of Identified Condition (statement of facts known about the issue, without hypothetical failures included): + Due to maintenance errors, the wrong lubricating oil was used in the high pressure core injection (HPCI) and reactor core isolation cooling (RCIC) turbines. Subsequently, the licensee determined that both HPCI and RCIC would have failed after running for about two hours. The errors were made 28 days prior to discovery.
