Nuclear Regulatory Commission May 4, 2010 – Federal Register Recent Federal Regulation Documents

The NRC proposes to amend its regulations to incorporate by reference the 2005 Addenda through 2008 Addenda of Section III, Division 1, and the 2005 Addenda through 2008 Addenda of Section XI, Division 1, of the ASME Boiler and Pressure Vessel Code (ASME B&PV Code); and the 2005 Addenda and 2006 Addenda of the ASME Code for Operation and Maintenance of Nuclear Power Plants (ASME OM Code). The NRC also proposes to incorporate by reference ASME Code Case N-722-1, ``Additional Examinations for PWR Pressure Retaining Welds in Class 1 Components Fabricated With Alloy 600/82/182 Materials Section XI, Division 1,'' and Code Case N-770, ``Alternative Examination Requirements and Acceptance Standards for Class 1 PWR [Pressurized- Water Reactor] Piping and Vessel Nozzle Butt Welds Fabricated with UNS N06082 or UNS W86182 Weld Filler Material with or without Application of Listed Mitigation Activities.''

The NRC is requesting public comment on the proposed model application (with model no significant hazards consideration determination) and model safety evaluation (SE) for plant-specific adoption of Technical Specifications Task Force (TSTF) Traveler TSTF- 500, Revision 2, ``DC Electrical RewriteUpdate to TSTF-360.'' The TSTF-500, Revision 2, is available in the Agencywide Documents Access and Management System (ADAMS) under Accession Number ML092670242. The proposed changes modify technical specification (TS) requirements related to direct current (DC) electrical systems in limiting condition for operation (LCO) 3.8.[4], [``DC SourcesOperating,''] LCO 3.8.[5], [``DC SourcesShutdown,''] and LCO 3.8.[6], [``Battery Parameters.''] A [new or revised] ``Battery Monitoring and Maintenance Program'' is being proposed for Section [5.5] [``Administrative ControlsPrograms and Manuals.''] This proposed model SE will facilitate expedited approval of plant-specific adoption of TSTF-500, Revision 2.
