INFORMATION REPORT SECY-07-0043 March 7, 2007
Contact: R. Taylor, OEDO Office of Nuclear Reactor Regulation (NRR) NRC Regulatory Issue Summary (RIS) 2007-02, "Clarification of NRC Guidance for Emergency Notifications During Quickly Changing Events" On February 2, 2007, the staff issued the subject RIS. The RIS described that it is not permissible to restart the 15-minute notification clock if degrading plant conditions cause an escalation in the declared emergency while the notification for the previous declaration was in progress. Public Meeting with Industry on Generic Safety Issue (GSI)-191 On February 7 and 8, 2007, the staff participated in a public meeting with the nuclear industry including the Nuclear Energy Institute, nuclear utilities, and vendors on GSI-191, "Assessment of Debris Accumulation on Pressurized Water Reactor (PWR) Sump Performance." The primary focus of the meeting was chemical effects and downstream (in vessel) effects. In the chemical effects area, presentations from the sump strainer vendors and PWR Owner's Group indicate that the initial industry testing strategy to account for chemical effects has encountered challenges. Currently, Westinghouse is performing tests to support the revision of its chemical model. The sump strainer vendors are revising their test plans and most vendors indicated revised testing would initiate in the late spring to summer time frame. Licensees are evaluating a number of options to address chemical effects including removal of fibrous insulation, changes to the post-Loss of Coolant Accident (LOCA) containment pool buffer, ability to back-flush the strainer, and water management to prevent debris from reaching the sump strainer. Meeting with Entergy Corporation on GSI-191 On February 9, 2007, the staff met with representatives of Entergy Corporation, the licensee for Indian Point, at NRC headquarters. Entergy described the existing containment sump configuration at Indian Point and the modifications completed or under consideration to address GSI-191. Entergy noted that both units will have much larger strainers installed by spring 2007, but that additional changes may be required to address chemical effects. Entergy discussed its strategy for handling post-LOCA debris, including a circuitous flowpath to the sumps through the incore instrumentation tunnel. Office of New Reactors (NRO) North Anna Early Site Permit (ESP) Hearing On February 8, 2007, counsel filed the staff's responses to the Atomic Safety and Licensing Board questions related to the Safety Evaluation Report for the North Anna ESP. This filing was in accordance with the Board's Order of January 18, 2007. On February 8, 2007, the ASLB held a Limited Appearance Session in Louisa County, Virginia. About 30 members of the public presented their views. Office of Nuclear Material Safety and Safeguards (NMSS) Meeting with Transnuclear Inc. (TN), to Discuss Amendment Request On February 8, 2007, staff met with TN to discuss their January 12, 2007, Standardized NUHOMS® design, amendment 10, application. The amendment proposes to: (1) add two new high heat-load, high-burnup dry shielded canisters (DSCs); (2) add a high-seismic version of the horizontal storage module; and (3) change the authorized contents for the NUHOMS®-24PTH DSC and the NUHOMS®-32PT DSC. TN requested an expedited review of it's application. The staff stated at the meeting that, given the complexity of the review, and assuming all issues can be resolved with one Request for Additional Information, a typical time for completing a safety evaluation report for this type of amendment request is approximately 1 year. Meeting with Holtec International to Discuss the HI-STAR 180 Transportation Package On February 13, 2007, staff met with Holtec International, to discuss a new application for the HI-STAR 180 transportation package. The HI-STAR 180 is unique because it uses METAMIC®, a neutron absorber, for the fuel basket material. Holtec is also proposing a bolted dual lid configuration. Either lid can act as the containment boundary. Holtec provided an introduction and brief overview of the design and special features of the new package. The application was submitted January 10, 2007. Meeting with Eureka County, Nevada, Officials On February 14, 2007, the NMSS Director and staff met with a County Commissioner, the Director of Public Works, and nuclear waste consultants for Eureka County, Nevada. As a recipient of nuclear waste funds, the county conducts oversight of the Yucca Mountain project, including full participation in the National Environmental Policy Act process, relative to the proposed repository. The county officials were particularly interested in NRC's process for deciding the extent to which it could adopt a final environmental impact statement for the repository. Eureka County officials' primary concerns relate to potential transportation impacts. Another topic of discussion was potential impacts of the Department of Energy's use of a Transportation, Aging, and Disposal Canister (TAD). Office of Information Services (OIS) Freedom of Information Act (FOIA) and Privacy Act (PA) Requests Received During the Period of February 9 through February 15, 2007:
