Notice of Availability of Model Application Concerning Technical Specification Improvement To Modify Requirements Regarding the Addition of LCO 3.0.9 on the Unavailability of Barriers Using the Consolidated Line Item Improvement Process
Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model safety evaluation (SE) and model application relating to the modification of requirements regarding the impact of unavailable barriers, not explicitly addressed in technical specifications, but required for operability of supported systems in technical specifications (TS). The NRC staff has also prepared 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 add an LCO 3.0.9 that provides a delay time for entering a supported system TS when the inoperability is due solely to an unavailable barrier, if risk is assessed and managed. Licensees of nuclear power reactors to which the models apply could then request amendments utilizing the model application, as generically approved by this notice, and confirming the applicability of the SE and NSHC determination to their reactors.
