ACTION:

Notice of availability.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is announcing the availability of Technical Specifications (TSs) Task Force (TSTF) Traveler TSTF-535, Revision 0, “Revise Shutdown Margin Definition to Address Advanced Fuel Designs,” 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-535 acceptable for inclusion in the following Standard Technical Specifications (STS): NUREG-1433, “Standard Technical Specifications General Electric Plants BWR/4,” and NUREG-1434, “Standard Technical Specifications General Electric Plants, BWR/6.”

SUPPLEMENTARY INFORMATION:

TSTF-535, Revision 0, is applicable to all boiling water reactor (BWR) power plants. The change revises the STS, NUREG-1433, “Standard Technical Specifications General Electric Plants BWR/4,” and NUREG-1434, “Standard Technical Specifications General Electric Plants, BWR/6.” Specifically, the change revises the STS definition of shutdown margin (SDM) to require calculation of SDM at the reactor moderator temperature corresponding to the most reactive state throughout the operating cycle (68 °F or higher). The purpose is to address newer BWR fuel designs, which may be more reactive at shutdown temperatures above 68 °F. This STS improvement is part of the CLIIP.

The NRC staff has reviewed the model application for TSTF-535 and has found Start Printed Page 13101it 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 change does not prevent licensees from requesting an alternate approach or proposing changes other than those proposed in TSTF-535, Revision 0. However, significant deviations from the approach recommended in this notice or the inclusion of additional changes to the license will 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-535, Revision 0.
