Reference:

1. Florida Power & Light Company letter L-2022-149, U4R33 Steam Generator Tube Inspection Report, October 4, 2022 (ADAMS Accession No. ML22277A803)

In Reference 1, Florida Power & Light Company (FPL) submitted the Turkey Point Unit 4 Cycle 33 Refueling Outage (U4R33) Steam Generator Tube Inspection Report, as required by Turkey Point Technical Specification (TS) 6.9.1.8. The report summarized the results of the Turkey Point Steam Generator (SG) tube inspection completed Fall 2022 in accordance with Turkey Point TS 6.8.4.j .

Subsequent to the Reference 1 submittal, FPL identified an error on page 1O of the report. Specifically, tube wear indications at broached support plates (TSP wear) in SG-8 were inadvertently copied to the TSP wear indication listing for SG-C as well. The issue has been entered into FPL's corrective action program (CAP) .

The attachment to this letter contains the corrected ECT data for page 10, as evidenced by the revision bar in the right-hand column . The corrected page 10 supersedes and replaces page 1O of Reference 1.

This letter contains no new regulatory commitments.

Should you have any questions regarding this submission, please contact Mr. Kenneth Mack, Fleet Licensing Manager, at 561- 904-3635.

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

Executed on the 30th day of March 2023 .
