By letter dated February 4, 2025, (ML25036A099), Florida Power and Light Company (FPL), submitted a license amendment request applicable to Turkey Point Unit 4. The request is to extend the implementation date for previously approved license amendment 291 related to reactor coolant pump seal replacement.
By email dated February 13, 2025, I transmitted a draft request for additional information (RAI) to you. You responded that no clarification was needed regarding the draft RAI. The final RAI is attached.
FPL has agreed to respond to the attached final RAI on or before February 28, 2025. The NRC staff considers that timely responses to RAIs help ensure sufficient time is available for staff review and contribute toward the NRCs goal of efficient and effective use of staff resources. If circumstances result in the need to revise the requested response date, please contact Perry Buckberg at (301) 415-1383 or via email at Perry.Buckberg@nrc.gov.

REQUEST FOR ADDITIONAL INFORMATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION REGARDING LICENSE AMENDMENT REQUEST TO EXTEND THE IMPLEMENTATION DATE FOR AMENDMENT 291 IN SUPPORT OF REACTOR COOLANT PUMP SEAL REPLACEMENT PROJECT TURKEY POINT NUCLEAR GENERATING STATION, UNIT 4 FLORIDA POWER AND LIGHT COMPANY DOCKET NO. 50-251 EPID NO.

Background===
By letter dated February 4, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25036A099), Florida Power and Light Company (FPL, the licensee), submitted a license amendment request (LAR) for Turkey Point Nuclear Generating Station, Unit No. 4 (Turkey Point).
The proposed amendment would modify the implementation date for Amendment No. 291 for Turkey Point issued on January 22, 2024 (ML23320A306), and corrected June 26, 2024 (ML24159A265). The U.S. Nuclear Regulatory Commission (NRC or the Commission) previously issued Amendment No. 291 with an implement date of by the completion of refueling outage 4R33 (spring 2025) for Unit No. 4.
L-2025-LLA-0026 APLB RAI 1:
The licensee stated in the LAR that the conversion to the new RCP seal design is a complex modification necessitating, amongst other changes, replacement of the rotating assembly seal housing and seal water injection piping, thereby requiring detailed planning, scheduling and equipment staging and that due to unforeseen circumstances, vendor fabrication of the seal conversion equipment is delayed.
The licensee also stated in the LAR that it chooses to complete the scheduled rotating assembly replacements but install another set of Flowserve NX seals during the Unit 4 spring 2025 outage and that the rotating assembly replacements will serve to reduce the installation scope and duration for the new RCP seal conversion during the following spring 2027 outage and that since the current Fire Protection Program reflects the current seal design, operating for an additional cycle will not present new or heightened operational risk.
Please explain what equipment is included in the rotating assembly replacements that will be completed during the Unit 4 spring 2025 outage and whether or not the equipment is considered like for like replacements or is considered new equipment needed to support the Framatome
RCP hydrostatic seal package equipped with the Passive Shutdown Seal (PSDS). If the latter, explain how this new equipment will properly work with the Flowserve NX seals and not increase risk during the time it is installed.
