TSTF-535, Revision 0, is applicable to all boiling water reactor (BWR) power plants. The proposed change revises the Standard Technical Specification (STS), NUREG-1433, “Standard Technical Specifications General Electric Plants BWR/4,” and NUREG-1434, “Standard Technical Specifications General Electric Plants, BWR/6.” Specifically, the proposed 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 consolidated line item improvement process (CLIIP).
This notice provides an opportunity for the public to comment on proposed changes to the STS after a preliminary assessment and finding by the NRC staff that the agency will likely offer the changes for adoption by licensees. This notice solicits comment on proposed changes to the STS, which if implemented by a licensee will modify the plant-specific TS. The NRC staff will evaluate any comments received for the
The proposed 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 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.
