Nuclear Regulatory Commission October 11, 2007 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model safety evaluation (SE) and a model application related to the modification of containment combustible gas control requirements in technical specifications (TS) for Boiling Water Reactors (BWR). The NRC staff has also prepared a model no-significant-hazards-consideration (NSHC) determination related to this matter. The purpose of these models is to permit the NRC to efficiently process license amendment applications that propose to adopt TSTF-478, Revision 2, ``BWR Technical Specification Changes that Implement the Revised Rule for Combustible Gas Control.'' TSTF-478, Revision 2, deletes Standard Technical Specification (STS) 3.6.3.3, ``Containment Atmosphere Dilution (CAD) System'' and modifies STS 3.6.3.1, ``Drywell Cooling System Fans,'' in NUREG-1433, ``Standard Technical Specifications General Electric Plants, BWR/4, Rev. 3,'' to establish TS for containment combustible gas control requirements as permitted by revised 10 CFR 50.44. Licensees of nuclear power reactors to which the models apply could then request amendments, confirming the applicability of the SE and NSHC determination to their plants. The NRC staff is requesting comment on the model SE, model application, and model NSHC determination prior to announcing their availability for referencing in license amendment applications.
