Technical Specification Improvement for Combustion Engineering Plants to Risk-Inform Requirements Regarding Conditions Leading to Exigent Plant Shutdown 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) relating to changes in Combustion Engineering (CE) plant conditions leading to exigent plant shutdown in technical specifications (TS). The NRC staff has also prepared a model no-significant-hazards- consideration (NSHC) determination relating to this matter and a model license amendment request (LAR). The purpose of these models is to permit the NRC to efficiently process amendments that propose to adopt technical specifications changes, designated as TSTF-426, related to Topical Report WCAP-16125-NP, Revision 0 (Rev 0), September 2003 (previously CE NPSD-1208, Rev. 0), "Justification for the Risk Informed Modifications to Selected Technical Specifications for Conditions Leading to Exigent Plant Shutdown," which was approved by an NRC SE dated July 9, 2004. Licensees of CE nuclear power reactors to which the models apply could then request amendments, confirming the applicability of the SE and NSHC determination to their reactors. The NRC staff is requesting comment on the model SE and model NSHC determination prior to announcing their availability for refer
