Reference:
- 1. Florida Power and Light Company (FPL) letter L-2012-077, "Turkey Point Nuclear Generating Station Units 3 and 4 License Amendment Request No. 220 - Permanent Alternate Repair Criteria (H*) for Steam Generator Expansion Region," April 30, 2012.

October 10, 2012.
Per Florida Power and Light Company (FPL) letter L-2012-077 (Reference 1) and pursuant to 10 CFR 50.90, FPL requested an amendment to the Technical Specifications (TS) of Renewed Facility Operating Licenses DPR-31 and DPR-41 for Turkey Point Units 3 and 4 to permanently revise TS 6.8.4.j, Steam Generator (SG) Surveillance Program, to exclude portions of the SG tube below the top of the SG tubesheet from periodic tube inspections.
FPL letter L-2012-373 (Reference 2) supplemented the Reference I submittal clarifying Regulatory Commitment Number 2 in Enclosure 5 of L-2012-077. Based on discussions with the Staff, a revision to Regulatory Commitment Number 2 is required. The attachment to this letter replaces Enclosure 5 of L-2012-077 in its entirety. The revision to Regulatory Commitment Number 2 does not impact the no significant hazards consideration determination previously submitted by Reference 1.
Please contact Mr. Robert Tomonto, Licensing Manager, at 305-246-7327 if there are any questions.

Turkey Point Units 3 and 4 will apply a factor of 1.82 to the operational leakage limit normal operating leakage associated with the tubesheet associated with the expansion region in the condition monitoring (CM) and Permanent Alternate operational assessment (OA). Specifically, for the CM Repair Criteria (PARC) assessment, the component of operational leakage from the and the 1.82 leakage prior cycle from below the H* distance will be multiplied by a factor will be established factor of 1.82 and added to the total accident leakage from any in the CMOA starting other source and compared to the allowable accident induced with the Unit 4 Cycle 27 leakage limit. For the OA, the difference between the RFO and the Unit 3 allowable accident induced leakage and the accident induced Cycle 27 RFO.
leakage from sources other than the tubesheet expansion region will be divided by 1.82 and compared to the observed operational leakage. An administrative operational leakage limit will be established to not exceed the calculated value.
