SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is announcing the availability of Technical Specifications (TSs) Task Force (TSTF) Traveler TSTF-426, Revision 5, “Revise or Add Actions to Preclude Entry into LCO [Limiting Condition for Operation] 3.0.3—RITSTF [Risk-Informed TSTF] Initiatives 6B & 6C,” for plant-specific adoption using the Consolidated Line Item Improvement Process (CLIIP). Additionally, the NRC staff finds the proposed TS (Volume 1) and TS Bases (Volume 2) changes in Traveler TSTF-426 acceptable for inclusion in the following Standard Technical Specification (STS): NUREG-1432, “Standard Technical Specifications Combustion Engineering Plants.”

SUPPLEMENTARY INFORMATION:

TSTF-426, Revision 5, is applicable to all Combustion Engineering-designed nuclear power plants. The change revises various TSs to add a Condition for loss of redundant features representing a loss of safety function for a system or component included within the scope of the plant TSs. It would replace Required Actions requiring either a default shutdown or explicit LCO 3.0.3 entry with a Required Action based on the risk significance for the system's degraded condition. This STS improvement is part of the CLIIP.

The NRC staff has reviewed the model application for TSTF-426 and has found it acceptable for use by licensees. Licensees opting to apply for this TS change are responsible for reviewing the NRC's staff SE and the applicable technical bases, providing any necessary plant-specific information, and assessing the completeness and accuracy of their license amendment request (LAR). The NRC will process each amendment application responding to the Notice of Availability according to applicable NRC rules and procedures.

The proposed changes do not prevent licensees from requesting an alternate approach or proposing changes other than those proposed in TSTF-426, Revision 5. However, significant deviations from the approach recommended in this notice or the inclusion of additional changes to the license require additional NRC staff review. This may increase the time and resources needed for the review or result in NRC staff rejection of the LAR. Licensees desiring significant deviations or additional changes should instead submit an LAR that does not claim to adopt TSTF-426, Revision 5.
