NRC Acceptance Review - Braidwood/Byron/Clinton - Adoption of TSTF-273, "Safety Function Determination Program Clarifications" Hi Phil, By letter dated July 30, 2021 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21211A585), Exelon Generation Company, LLC (Exelon) submitted a license amendment request to adopt Technical Specification Task Force Traveler 273 (TSTF-273) at Braidwood Station, Units 1 and 2, Byron Station, Unit Nos. 1 and 2, and Clinton Power Station, Unit 1. Specifically, the proposed technical specification (TS) changes adds explanatory text to the LCO 3.0.6 Bases clarifying the "appropriate LCO for loss of function," and that consideration does not have to be made for a loss of power in determining loss of function.
Explanatory text is also added to the programmatic description of the Safety Function Determination Program (SFDP) in TS 5.5.15 (Braidwood Station and Byron Station) and TS 5.5.10 (Clinton Power Station) to provide clarification of these same issues. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
The NRC staff has reviewed the submittal and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed alternative in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.
Based on the information provided in your submittal, the NRC staff has estimated that this request will take approximately 115 hours0.00133 days <br />0.0319 hours <br />1.901455e-4 weeks <br />4.37575e-5 months <br /> to complete. The NRC staff expects to complete this review in approximately 12 months from the date of this acceptance, which is August 2022. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager.
If you have any questions, please contact me at (301) 415-6606.
