Mail Stop: EX/JB Juno Beach, FL 33408

SUBJECT:

TURKEY POINT NUCLEAR GENERATING UNIT NOS. 3 AND 4 REGULATORY AUDIT

SUMMARY

FOR THE REVIEW OF LICENSE AMENDMENT REQUEST TO REVISE THE FIRE PROTECTION PROGRAM IN SUPPORT OF REACTOR COOLANT PUMP SEAL REPLACEMENT PROJECT (EPID L-2022-LLA-0128)

Dear Mr. Coffey:

By application dated August 26, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22243A161), Florida Power & Light Company (FPL, the licensee) submitted a license amendment request (LAR) for the Turkey Point Nuclear Generating Unit Nos. 3 and 4.

The proposed LAR will revise the operating license, paragraph 3.D, Fire Protection, for fire protection program changes that may be made without prior U.S. Nuclear Regulatory Commission (NRC) approval. One of the criter ia for such a change is that the risk increase resulting from the change is less than 1x10-7/year (yr) for CDF [core damage frequency] and less than 1 x 10-8/yr for LERF [large early release frequency]. The change is to support replacement of the currently installed reactor coolant pump (RCP) seals with the Framatome RCP hydrostatic seal package equipped with the Passive Shutdown Seal.

B. Coffey

The NRC staff reviewed FPLs LAR and determined that a regulatory audit would assist in the timely completion of the LAR review. The NRC staff conducted a regulatory audit that consisted of a remote audit from March 9 to June 29, 2023. The audit plan was provided to Mr. Jarrett Mack of your staff by email dated January 5, 2023 (ML23006A026). The audit plan included a list of items to be provided on an electronic portal. The staff reviewed these documents and held discussions with members of FPL on the LAR relevant to the NRC staffs review. The results of the regulatory audit were used by the NRC staff to finalize requests for additional information, which were issued by email dated May 5, 2023 (ML23129A832), and August 14, 2023 (ML23226A075). The audit summary for the audit is enclosed.

Sincerely,

/RA/

SUMMARY

REGARDING LICENSE AMENDMENT REQUEST TO

REVISE THE FIRE PROTECTION PROGRAM IN SUPPORT OF

REACTOR COOLANT PUMP SEAL REPLACEMENT PROJECT

TURKEY POINT NUCLEAR GENERATING UNIT NOS. 3 AND 4

DOCKET NOS. 50-250 AND 50-251

EPID NO. L-2022-LLA-0128

1.0 BACKGROUND

The regulatory audit is a planned license or regulation-related activity that includes the examination and evaluation of primarily non-docketed information. The regulatory audit is conducted with the intent to gain understanding, to verify information, and/or to identify information that will require docketing to support the basis of a licensing or regulatory decision.

Performing a regulatory audit of a licensees information is expected to assist the U.S. Nuclear Regulatory Commission (NRC) staff in efficientl y conducting its review or gain insights on the licensees processes or procedures. Information that the NRC staff relies upon to make the safety determination must be submitted on the docket. However, the NRC staff may review supporting information retained as records under Title 10 of the Code of Federal Regulations (10 CFR) 50.71, Maintenance of records, making of reports, and/or 10 CFR 54.37, Additional records and recordkeeping requirements, which, although not required to be submitted as part of the licensing action, would help the staff better understand the licensees submitted information.

By application dated August 26, 2022 (Agen cywide Documents Access and Management System (ADAMS) Accession No. ML22243A161), Florida Power & Light Company (FPL, the licensee) submitted a license amendment request (LAR) for the Turkey Point Nuclear Generating Unit Nos. 3 and 4 (Turkey Point).

The proposed LAR will revise the operating license, paragraph 3.D, Fire Protection, for fire protection program changes that may be made without prior NRC approval. One of the criteria for such a change is that the risk increase resulting from the change is less than 1x10-7/year (yr) for CDF [core damage frequency] and less than 1 x 10-8/yr for LERF [large early release frequency]. The change is to support replacement of the currently installed reactor coolant pump (RCP) seals with the Framatome RCP hydrostatic seal package equipped with the Passive Shutdown Seal.

An audit team consisting of NRC staff conducted a remote regulatory audit to support the review of the LAR from March 9 to June 29, 2023. The purpose of the audit was to gain an understanding of the information needed to support the NRC staffs licensing decision regarding the LAR and to develop requests for additional information (RAIs).

Enclosure

The information submitted in support of the LAR is under final review, and any additional information needed to support the LAR review will be formally requested by the NRC staff using the RAI process in accordance with the Office of Nuclear Reactor Regulation Office Instruction LIC-101, Revision 6, License Amendment Review Procedures (ML19248C539).

2.0 AUDIT ACTIVITIES AND OBSERVATIONS

The NRC audit team consisted of NRC staff. The list of attendees from the NRC, FPL, and FPLs contractors is provided in Section 4.0.

During the remote regulatory audit, the NRC audit team held an entrance meeting with FPL on March 9, 2023. During the remainder of the remote audit, the NRC audit team participated in technical discussions with FPL according to the audit plan dated January 5, 2023 (ML23006A026). The NRC audit team held an exit meeting with FPL on June 29, 2023, where the NRC staff provided a brief conclusion of the teams goals, objectives, and technical discussions. Section 5.0 contains a list of the documents audited by the NRC audit team.

3.0 RESULTS OF THE AUDIT

As a result of the remote regulatory audit, RAIs were issued to FPL on May 5, 2023 (ML23129A832) and August 14, 2023 (ML23226A075). FPL provided responses to the RAIs in supplements dated May 31, 2023 (ML23151A607), July 27, 2023 (ML23208A191), and August 25, 2023 (ML23240A153).
