Model Safety Evaluation for Plant-Specific Adoption of Technical Specifications Task Force Traveler TSTF-432, Revision 1, “Change in Technical Specifications End States (WCAP-16294)” Using the Consolidated Line Item Improvement Process

The U.S. Nuclear Regulatory Commission (NRC) is announcing the availability of the model safety evaluation (SE) for plant-specific adoption of Technical Specifications (TSs) Task Force (TSTF) Traveler TSTF- 432, Revision 1, "Change in Technical Specifications End States (WCAP- 16294)." The proposed change revises the Improved Standard Technical Specification (ISTS), NUREG-1431, "Standard Technical Specifications Westinghouse Plants," to permit, for some systems, entry into a hot shutdown (Mode 4) end state rather than a cold shutdown (Mode 5) end state. The model SE will facilitate expedited approval of plant- specific adoption of TSTF-432, Revision 1. This TS improvement is part of the consolidated line item improvement process.
