INFORMATION REPORT SECY-04-0106 June 28, 2004
Contact: T. Kim, OEDO Office of Nuclear Reactor Regulation Public Meeting Regarding the Mitigating Systems Performance Index (MSPI) On June 17, 2004, Office of Nuclear Reactor Regulation (NRR) staff held the monthly public meeting regarding the MSPI. The staff stated that it had not yet received all of the internal stakeholder responses to its May 25, 2004, memorandum that requested identification of critical issues requiring resolution prior to the implementation of MSPI as an alternative to the current Safety System Unavailability (SSU) Performance Indicator (PI). The staff also stated that its goal was to have an agency position on these issues and how to proceed forward by the next monthly meeting scheduled for July 21, 2004. Industry led a discussion of implementation issues if the decision was made to proceed forward with the MSPI. This includes creation of a committee to work on a draft temporary instruction (TI), MSPI implementation guidance, a list of significant differences and assumptions that need to be resolved as a result of the standardized plant analysis risk (SPAR) upgrade and validation reviews for the pilot plants, as well as a sample MSPI basis document to be used in the public workshops. Issuance of Revision to 10 CFR 50.48, "Fire Protection" On June 16, 2004, NRC published a final revision to 10 CFR 50.48, "Fire Protection," in the Federal Register (69 FR 33536). This rule allows current reactor licensees to adopt a set of risk-informed, performance-based fire protection requirements contained in the National Fire Protection Association Standard 805 as an alternative to the existing deterministic, prescriptive fire protection requirements. The final rule becomes effective July 16, 2004. Office of Nuclear Material Safety and Safeguards Louisiana Energy Services Uranium Enrichment Plant Prehearing Conference On June 15, 2004, NRC staff attended a prehearing conference in Hobbs, New Mexico, to discuss proposed contentions raised on the Louisiana Energy Services' uranium enrichment plant proposed to be located in Eunice, New Mexico. Staff from the New Mexico Environment Department, New Mexico Attorney General's office, and Nuclear Information and Resource Service/Public Citizen presented their proposed contentions. Discussion followed the written filings made by the parties. The Atomic Safety and Licensing Board is scheduled to rule on the admissibility of these contentions by mid-July. Center for Nuclear Waste Regulatory Analyses Staff Presentation at CALPHAD (CALculation of PHAse Diagrams) in Krakow, Poland On May 31-June 4, 2004, staff from the Center for Nuclear Waste Regulatory Analyses (hereafter, the Center) attended an International Conference on Phase Diagram Calculations and Computational Thermochemistry. The Center staff presented a talk entitled "Phase Stability of Alloy 22 High-Level Waste Container Weldments: Experiments and Thermodynamic Calculations." The paper discussed results of recent work investigating the effects of fabrication processes on the material stability of Alloy 22, which is a proposed corrosion- resistant waste package material to be used in a potential geologic repository at Yucca Mountain, Nevada. Meeting on Clearance of Solid Materials On June 15, 2004, a staff member from the Division of Industrial and Medical Nuclear Safety participated in a panel discussion on the "Clearance of Solid Materials: Federal and Industry Update," at the 2004 American Nuclear Society annual meeting in Pittsburgh, Pennsylvania. Other panelists included representatives from the Department of Energy, Council of Radiation Control Program Directors, and various NRC licensees. Feedback from presentations and audience discussion was largely in favor of some kind of clearance approach. Participants provided the following reasons for why clearance and a codified regulatory approach are needed: (1) the need for filling a regulatory void; (2) the costs of managing such materials; (3) conservation of space at low-level waste facilities; (4) conservation (through recycling) of valuable resources; and (5) a reduction in risk and costs. Office of Nuclear Regulatory Research International Workshop on Communication on Risk Reduction An international workshop on "Communication on Risk Reduction" was held in Moscow, Russia, on June 7-9, 2004. The workshop was co-sponsored by the NRC and the Institute of Nuclear Safety (IBRAE) of the Russian Academy of Sciences (RAS). More than 50 participants including representatives from Russia, Austria, Belarus, France, Germany, Ukraine, and USA, shared information on approaches and methods for reducing risk and enhancing safety, and discussed associated cost and benefit considerations. While approaches for assessing cost and benefit of safety enhancements varied among different countries, the use of probabilistic risk assessment (PRA) results and insights appears to be a common key input for these assessments. Additionally, Russian representatives indicated that a new common regulatory system based on safety/risk concepts is under consideration for all Russian industries. They further indicated that information discussed at the workshop would be very useful to their Russian colleagues as safety/risk concepts become a key element in the Russian regulation. Probabilistic Risk Assessment Workshop On June 9, 2004, RES staff gave a presentation at the Region I Probabilistic Risk Assessment (PRA) Workshop in Coatesville, PA. The workshop involved both Region I staff and licensee PRA staff. The staff's presentation discussed the results of comparisons between the Standardized Plant Analysis Risk (SPAR) models and licensees' PRAs which were performed during the onsite quality assurance (QA) reviews of the Revision 3 SPAR models and the comparison exercise conducted with the pilot plants in the Mitigating Systems Performance Index (MSPI) development program. The staff also identified the major factors that have been determined to influence the differences observed between the SPAR model results and those obtained with the licensees' PRAs. The presentation led to detailed discussions of the Phase 3 analyses in the Significance Determination Process (SDP) and the recently undertaken Risk Assessment Standardization Project (RASP) effort being conducted jointly by NRR and RES. NRC Public Meeting on External Events Probabilistic Risk Analysis Standard On June 10, 2004, the RES staff held a public meeting on the development of Appendix C to Regulatory Guide (RG) 1.200, "An Approach for Determining the Technical Adequacy Of Probabilistic Risk Assessment Results For Risk-Informed Activities." Appendix C to RG 1.200 will provide the staff's regulatory position on the American National Standard (ANS) on external events probabilistic risk analysis methodology. The purpose of the meeting was to present the staff's preliminary observations and questions on this standard. The ANS representative attending the meeting indicated that the NRC staff's observations were useful and that ANS would continue to work with the staff to resolve questions. A second public meeting is scheduled for August 2, 2004. The staff expects to release the draft Appendix C for formal public review and comment by the end of August 2004. Organization for Economic Cooperation and Development - Melt Coolability and Concrete Interaction (OECD-MCCI) Program The fifth OECD-MCCI Program Review Committee (PRC) and Management Board (MB) meetings were held on June 2-4, 2004, at the Commissariat l'Energie Atomique (CEA) Cadarache Laboratory in France. Among the topics discussed at the meeting were the results of a two-dimensional core-concrete interaction test (CCI-1) and two small-scale water ingression and crust strength tests (SSWICS-5 and SSWICS-6), all conducted at the Argonne National Laboratory (ANL) within the past six months. The CCI-1 test was conducted to generate the two-dimensional concrete erosion data involving reactor core material. The data will be used to improve the core-concrete interaction model in NRC's severe accident computer code, MELCOR. The current model is based on one-dimensional experimental data, and is not capable of predicting the two-dimensional concrete erosion process in a reliable manner. The SSWICS tests are providing data for modeling water ingression as a means of cooling ex-vessel core debris. Future tests discussed at the meeting included a second core-concrete interaction test, the seventh SSWICS test (SSWICS-7) and the first melt eruption test (MET-1). The OECD-MCCI Program is hosted and coordinated by NRC with participation by 13 OECD countries and by the U.S. Department of Energy. The outcome of the OECD-MCCI Program is expected to determine the efficacy of severe accident management strategy of flooding the reactor cavity in the unlikely event of a severe core damage accident that may lead to vessel failure and relocation of molten debris on the cavity floor. Results from water ingression, core-concrete interaction, melt eruption, and crust strength tests will be used to develop coolability models for incorporation into NRC's severe accident code. USEC, Inc., Gas Centrifuge Workshop On June 16, 2004, RES staff participated in a workshop at Oak Ridge, Tennessee, on gas centrifuge technology. The workshop involved presentations by recognized gas centrifuge experts, as well as tours of USEC's facilities. USEC, Inc., plans to submit an application for a commercial gas centrifuge plant in August 2004. Nuclear Security and Incident Response Preliminary Notifications
Office of Administration Licensing Proceeding for a High-Level Radioactive Waste Geologic Repository: Licensing Support Network, Submissions to the Electronic Docket (AH31- Part 2) On June 14, 2004 (69 FR 32836), a final rule that amends the Commission's Rules of Practice was published in the Federal Register. The final rule addresses the use of the Licensing Support Network (LSN) and the electronic docket in the licensing proceeding on the disposal of high-level radioactive waste at a geologic repository. The amendments establish basic requirements and standards for submission of adjudicatory materials to the electronic docket by parties to the high-level radioactive waste licensing proceeding. The amendments also address the issue of reducing the unnecessary loading of duplicate documents on individual participant LSN document collection servers, the continuing obligation of LSN participants to update their documentary material, the Secretary of the Commission's determination that the Department of Energy licensing application is electronically accessible, and material that may be excluded from the LSN. The final rule becomes effective July 14, 2004. Chief Information Officer ADAMS User Group (AUG) Meets at NRC Headquarters The ninth meeting of the Agencywide AUG was held on June 16, 2004. Approximately 14-16 AUG members and NRC staff participated in the meeting. Agenda items, which were submitted in advance, included several issues related to the Web-based access to ADAMS, including the status of future system upgrades.

Region I Salem and Hope Creek The NRC conducted the annual assessment meeting with Public Service Electric and Gas Company (PSEG) for the Salem and Hope Creek stations on June 16, 2004. The meeting also included discussions of the results of three assessments PSEG had undertaken to review the work environment at the Salem and Hope Creek stations, as well as PSEG's plans for improving that environment. PSEG stated that it is developing a comprehensive plan to improve not only the work environment, but also the corrective action and work management programs. PSEG corporate officers reiterated a commitment to dedicate needed resources to improve the material condition of the facilities as well as the work environment; to docket a description of its action plan by June 25, 2004; to periodically meet with the NRC to discuss progress, and conduct periodic assessments to measure improvement. Following the meeting with PSEG, State and local officials and members of the public were offered an opportunity to ask questions of the NRC staff. Those comments included requests that the units be shut down. Vermont Yankee (VY) Missing Fuel Investigation A Region I inspector was on site the week of June 14, 2004 to follow the licensee's investigation into the missing fuel rod segments from VY. Entergy completed in-pool inspections and continues to review records and interview personnel for the investigation. Entergy expects to complete its investigation report by the end of July, with the root cause analysis report to follow. NRC plans to conduct a special inspection of the licensee's investigation beginning August 2, 2004. Entergy submitted an Licensee Event Report (LER) describing the known details related to the missing fuel segments, including radionuclide content. The LER revised the size of the smaller of the two segments from a previously reported 7 inches (based on plant records from the 1979-80 period) to 9 inches. This change was due to more accurate measurement of the piece of the fuel rod remaining in the VY spent fuel pool. Representatives of the NRC Office of the Inspector General were also on site this week observing portions of the inspection. Buffer Zone Protection Plan Survey The Department of Homeland Security (DHS) is developing a program to provide local law enforcement agencies (LLEA) with the response tools to provide better security support to nuclear power plant security forces. On July 16-17, 2004, DHS, the Pennsylvania State Police and other LLEA conducted a pilot Buffer Zone Protection Plan Survey at the Limerick Generating Station. The product of the pilot will be used as a model Buffer Zone Protection Plan Survey to be conducted at all other nuclear power plants in the future.
