RE: NRC Acceptance Review: St Lucie, Units 1 and 2 - License Amendment to Allow Risk Informed Completion Times (RICT) for the 120-Volt AC (EPID L-2020-LLA-0283)

Date: Tuesday, January 19, 2021 8:48:00 AM Wyatt/Ken, I apologize but I listed the estimated completion date as 1/15/2021 instead of 2022. This email below supersedes that sent to you on 1/15/2021.

Mr. Godes, By letter dated December 21, 2020 (Agencywide Documents Access and Management System Accession No. ML20356A162), Florida Power & Light Company (the licensee) requested amendments to the Renewed Facility Operating License Nos. DPR-67 and NPF-16 for St. Lucie Plant, Units 1 and 2, respectively. The proposed license amendments would revise the St. Lucie Operating Licenses and Technical Specifications (TS) to permit the application of risk-informed completion times (RICT) for the 120-Volt AC Instrument Bus requirements, consistent with TSTF-505 , Revision 2, "Provide Risk-Informed Extended Completion Times RITSTF Initiative 4b". The purpose of this correspondence is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this amendment 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.

Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the TSs) must fully describe the changes requested, and following as far as applicable, the form prescribed for original application. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.

The NRC staff has reviewed your submittal and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the amendment request 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. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that the LAR will take approximately 710 hours0.00822 days <br />0.197 hours <br />0.00117 weeks <br />2.70155e-4 months <br /> to complete. The NRC staff expects to complete the review of the licensing action by January 15, 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. These estimates are based on the NRC staffs initial review of the application and they could change, due to several factors including requests for additional information, unanticipated addition of scope to the review, and review by NRC advisory committees or hearing-related activities. Additional delays may occur if the submittal is provided to the NRC in advance of or in parallel with industry program initiatives or pilot applications. If you have any questions, please contact me at (301) 415-7410.

Thanks,

-Nate Natreon (Nate) Jordan Nuclear Engineer (Project Manager)
