L-2023-054 Page 2 of2 Semi-Annual Update of the Operational Programs Implementation Schedule - Pursuant to the PTN 6

& 7 COLs Section 2.D.(11), the schedule for implementation of operational programs is to be updated every six months. Because there are no changes to FPL's construction decision, the schedule provided in Reference 3 is reaffirmed.

Annual 10 CFR 50.46 Report - The PTN 6 & 7 COLs incorporate by reference AP1000 Design Certification Document (DCD) Revision 19, and thus also the peak fuel cladding temperature calculations performed by Westinghouse Electric Corporation (\\v'EC). Accordingly, the \\v'EC 2022 Model Year 10 CFR 50.46 annual report for the AP1000 Design Certification Analysis of Record (AOR) applies to PTN 6 & 7 (Reference 4).

As described in the Reference 4 letter, there are no new emergency core cooling system model changes that impact peak cladding temperature (PCT) for the 2022 model year. The estimated PCT for the limiting transient, the Best Estimate Large Break Loss-of-Coolant Accident, remains at 2010°F and does not exceed the 10 CFR 50.46(6)(1) acceptance criterion of 2200°F. The summary of the AP1000 Design Certification AOR PCT margin allocations and their bases is provided in Attachment 1 of the Reference 4 letter.

If you have any questions, or need additional information, please contact Michael Davis, Licensing Projects Manager, at 319-851-7032.

I declare under penalty of perjury that the foregoing is true and correct.

Executed on 12th day of April 2023.
