Notice of Availability of Model Application Concerning Technical Specification Improvement To Revise Containment Isolation Valve Completion Times (TSTF-498, Revision 1, for Babcock & Wilcox Plants)

Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model safety evaluation (SE) relating to the modification of technical specification (TS) 3.6.3, Containment Isolation Valves associated with implementation of BAW- 2461-A, "Risk-Informed Justification for Containment Isolation Valve Allowed Outage Time Change." The NRC staff has also prepared a model license amendment request and a model no-significant-hazards consideration (NSHC) determination relating to this matter. The purpose of these models is to permit the NRC to efficiently process amendments that propose to modify TS Completion Times (CTs) for CIVs. Licensees of nuclear power reactors to which the models apply can then request amendments after confirming the applicability of the SE and NSHC determination to their reactors. Licensees of nuclear power reactors to which the model applies may request amendments using the model application.
