NRC Acceptance Review: St Lucie, Units 1 and 2 RR#2 and RR#5 (EPID L-2020-LLR-0020)

Date: Thursday, February 20, 2020 3:27:00 PM Mr. Godes, By letter dated January 27, 2020 (Agencywide Documents Access and Management System Accession No. ML20027B419), Florida Power & Light Company (the licensee) requested relief from the American Society of Mechanical Engineers Code (ASME Code),

Section XI for the St. Lucie Nuclear Plant, Unit 1 (St. Lucie, Unit 1) Fifth 10-Year Inservice Inspection (ISI) Interval and the St. Lucie Nuclear Plant, Unit 2 (St. Lucie, Unit 2) Fourth 10-Year ISI Interval, respectfully. Specifically, relief is being requested from the schedule of reactor pressure vessel (RPV) bolting examinations specified in ASME Section XI Code, Table IWB-2500-1, Category B-G-1, and IWB-2420, in order to accommodate an additional set of reactor vessel closure studs, nuts, and washers that are shared between St. Lucie, Units 1 and 2. Alternatively, the licensee specified the following: The licensee will continue to perform the ASME required nondestructive examinations (NDE) examinations of RPV bolting between scheduled refueling outages while the bolting is being cleaned and prepared for service in the opposite unit. Examinations will continue to be performed of all three sets of bolting during the St. Lucie, Unit 1 Fifth Interval and the St. Lucie, Unit 2 Fourth Interval in accordance with Code Category B-G-1 requirements and applicable relief requests. The bolting will continue on a 10-year schedule for examination. Additionally, as part of the preparation for service process, the licensee will continue to perform visual examinations of each bolting set in accordance with maintenance procedures.

The NRC staff has reviewed your application 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 assessment regarding the acceptability of the proposed 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, you should be aware that there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified. 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 review of the proposed alternative will take approximately 140 hours0.00162 days <br />0.0389 hours <br />2.314815e-4 weeks <br />5.327e-5 months <br /> to complete. The NRC staff expects to complete the review within one year of this acceptance (i.e., by February 2021). 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. If you have any questions, please contact me at (301) 415-7410.

Thanks,

-Nate
