1. Florida Power & Light Company letter L-2014-029 date July 14, 2014, "License Amendment Request, Application to Revise Technical Specification to Adapt Technical Specifications Task Force (TSTF) Traveler-523, "Generic Letter 200801, Manage Gas Accumulation," Using the Consolidated Line Item Improvement Process," Accession No. ML14198A074.

2. NRC Letter dated June 22, 2015, "St. Lucie Plant, Unit Nos. 1 and 2 - Issuance of Amendments Regarding Risk-Informed Justifications for the Relocation of Specific Surveillance Frequency Requirements to a Licensee-Controlled Program (TAC Nos.

MF3495 AND MF3496)," Accession No. ML15127A066.

In Reference 1, Florida Power & Light Company (FPL) submitted a request for an amendment to the Technical Specifications (TS) for St. Lucie Units 1 and 2. This amendment would incorporate TSTF-523 as the means for satisfying gas management Technical Specification requirements as required by Generic Letter 2008-01. Although the license amendment request

([AR) was developed with the surveillance frequencies embedded in the associated TS surveillance requirements, the TSTF also allowed relocation of the surveillance frequency requirements into a Surveillance Frequency Control Program (SFCP) for licensees with that program.

In Reference 2, the NRC approved TS amendments 223 and 173 (St. Lucie Units I and 2, respectively) that allows St. Lucie to implement a SFCP. The approved changes were consistent with U.S. Nuclear Regulatory Commission (NRC)-approved TS Task Force Standard TS change TSTF-425, "Relocate Surveillance Frequencies to Licensee Control - RITSTF [Risk-Informed TS Task Force] Initiative Sb," Revision 3.

This letter provides new TS markups and justification for the TSFT-523 LAR utilizing the SFCP TS surveillance requirement option that was approved by the NRC in Reference.2. The no significant hazards consideration conclusion in Reference 1 bounds the changes. Although not provided in this correspondence, the.TS Bases for the associated TSs will be revised to include the use of the.SFCP.

FPL requests a 120 day implementation period for this [AR. This letter contains no new.

regulatory commitments and does not modify any existing commitments.

St. Lucie Units 1 and 2 L-201 5-180 Docket Nos. 50-335 and 50-389 ATTACHMENT 1 Justification for the Chanqie TSTF-425 allowed licensees to relocate surveillance frequencies to the Surveillance Frequency Control Program (SFCP). TSTF-523 provided an option to relocate the gas accumulation surveillance frequencies into the SFCP. The use of the SFCP was approved subsequent to the submittal of this TSTF-523 LAR.

The provided markups simply replaced any referenced TS surveillance requirement frequency (e.g., "every 31 days," etc.) with the phrase "in accordance with the Surveillance Frequency Control Program," as allowed by TSTF-523. Any differences between the TSTF and FPL's proposed wording and format are due to the custom nature of the St. Lucie's TSs. Therefore, the intent of TSTF-523 is met and these proposed changes are administrative in nature.

With less than the required shutdown cooling loops OPERABLE, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> initiate corrective action to return the required loops to OPERABLE status, or to establish greeter than or equal to 23 feet of water above the reactor pressure vessel flange, as soon as possible.

b.

With no shutdown cooling loop in operation, suspend operations that would cause introduction into the RCS, coolant with boron concentration less than required to meet the boron concentration of Technical Specification 3.9.1 and within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> initiate corrective action to return the required shutdown cooling loop to operation, Close all containment penetrations providing direct access from the containment atmosphere to the outside atmosphere within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

SURVEILLANCE REQUIREMENTS 4.9.8.2 In accordance with the Surveillance Frequency Control Program:

a.

At least one shutdown cooling loop shall be verified to be in operation.

b.

The total flow rate of reactor coolant to the reactor pressure vessel shall be verified to be greater than or equal to 3000 gpm.*

c.

Verify shutdown cooling trains locations susceptible to gas accumulation are sufficiently filled with water.

The reactor coolant flow rate requirement may be reduced to 1850 gpm if the following conditions are satisfied before the reduced requirement is implemented: the reactor has been determined to have been subcritical for at least 125 hours0.00145 days <br />0.0347 hours <br />2.066799e-4 weeks <br />4.75625e-5 months <br />, the maximum ROS temperature is <_ 11 70F, and the temperature of CCW to the shutdown cooling heat exchanger is < 87°F.

One required shutdown cooling loop may be inoperable for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for surveillance testing, provided that the other shutdown cooling loop is OPERABLE and in operation.
