Notice of Availability of Model Application Concerning Technical Specification Improvement To Extend the Completion Times for Inoperable Containment Isolation Valves at General Electric 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 Standard Technical Specifications (STSs) 3.6.1.3, "Primary Containment Isolation Valves (PCIVs)," for boiling-water reactors (BWR) in NUREG-1433, Revision 3, "Standard Technical Specifications, General Electric Plants, BWR/4," and "NUREG-1434, Revision 3, "Standard Technical Specifications, General Electric Plants, BWR/6." The proposed change to the STSs 3.6.1.3 would extend to 7 days the completion time (CT) (or allowed outage time (AOT)) to restore an inoperable PCIV to operable status or isolate the affected penetration flow path both for selected primary containment penetrations with two (or more) PCIVs and for selected primary containment penetrations with only one PCIV. This change is based on analyses provided in a generic topical report (TR) submitted by the BWR Owners' Group (BWROG). The BWROG, through its participation in the Technical Specification (TS) Task Force (TSTF) proposed this change to the STSs in Change Traveler No. TSTF-454, Revision 1. This notice also includes a model safety evaluation (SE) and a model no significant ha
