Notice of Availability of Model Application Concerning Technical Specification Improvement To Extend the Completion Times for Inoperable Containment Isolation Valves at Combustion Engineering Plants Using the Consolidated Line Item Improvement Process

Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model application relating to changes to the completion time in Standard Technical Specifications (STS) 3.6.3, "Containment Isolation Valves (Atmospheric and Dual)," for Combustion Engineering (CE) plants. The change to the Technical Specifications (TSs) would extend to 7 days the completion time to isolate the affected penetration flow path when selected containment isolation valves (CIVs) are inoperable in either a penetration flow path with two CIVs or in a penetration flow path with one CIV in a closed system. These changes are based on Revision 2 of Technical Specification Task Force (TSTF) change traveler TSTF-373, "Increase CIV Completion Time in Accordance with CE-NPSD-1168," which has been approved for incorporation into the STS for CE plants (NUREG-1432). The purpose of this model is to permit the NRC to efficiently process amendments that propose to modify TSs to extend the completion time for CIVs. Licensees of nuclear power reactors to which the model applies may request amendments using the model application.
