Nuclear Regulatory ConmmissionAttn.: Document Control DeskWashington, D.C. 20555-0001Re: Turkey Point Units 3 and 4Docket Nos. 50-250 and 50-251Administrative License Amendment Request No. 223 RegardingControl Room Emergency Ventilation System Technical SpecificationReference:(1) J. Paige (NRC) to M. Nazar (FPL), "Turkey Point Units 3 and 4 -"Issuance of AmendmentsRegarding Alternative Source Term (TAC Nos. ME1624 and ME1625)," Accession No.ML1 10800666, June 23, 2011.On June 23, 2011, the U.S. Nuclear Regulatory Commission (NRC) issued Amendment Nos. 244and 240 to Renewed Facility Operating License Nos. DPR-31 and DPR-41 for the Turkey PointNuclear Plant, Units Nos. 3 and 4, respectively, with supporting Safety Evaluation Report (SER)regarding the Alternative Source Term (AST) [Reference 1].During implementation of these amendments, it has been identified that a correction is needed toaddress a clerical error identified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6that omitted an applicable footnote. The footnote for Modes 1-4 also needs to be modified for Modes5-6 to include core alterations and positive reactivity changes as well as fuel movement in order to beconsistent with the intent of the FPL responses to the NRC Requests for Additional Information (RAI)regarding AST and the Control Room Emergency Ventilation System (CREVS). If not corrected, TS3.7.5 Action "c", as currently worded, could interfere with core refueling activities for the Unit 4Cycle 27 Refueling Outage scheduled for later this fall.Description of the proposed TS change with supporting justification and a no significant hazardsdetermination and environmental consideration are provided in the Enclosure to this letter.The Turkey Point Plant Nuclear Safety Committee (PNSC) has reviewed the proposed licenseamendments. The proposed TS change has been evaluated in accordance with 10 CFR 50.91(a)(1),using the criteria in 10 CFR 50.92(c). FPL has determined that the proposed TS change does notinvolve a significant hazards consideration.FPL has determined that the proposed amendments involve no significant increase in the amountsor types of any effluents that may be released offsite, and no significant increase in individual orcumulative occupational radiation exposure. Therefore, FPL has concluded that the proposedamendments meet the criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and,pursuant to 10 CFR 51.22(b), an environmental impact statement or environmental assessmentneed not be prepared in connection with issuance of the amendments.This letter contains no new commitments and no revisions to existing commitments.FPL requests that this license amendment request be approved and the revised TS issued prior tothe onset of the Unit 4 Cycle 27 refueling outage scheduled to commence on November 5, 2012.Florida Power & Light Company9760 SW 344 St., Florida City, FL 33035 142 0X-(PL Turkey Point Nuclear Plant L-2012-313Docket Nos. 50-250 and 50-251 Page 2 of 2In accordance with 10 CFR 50.91(b)(1), a copy of this letter is being forwarded to the StateDesignee of Florida.Should you have any questions regarding this submittal, please contact Mr. Robert J.

The footnote for Modes 1-4 also needs to be modified for Modes 5-6 toinclude core alterations and positive reactivity changes as well as fuel movement in order tobe consistent with the intent of the FPL responses to the NRC Requests for AdditionalInformation (RAI) regarding the Alternative Source Term (AST) and the Control RoomEmergency Ventilation System (CREVS). If not corrected, TS 3.7.5 Action "c", as currentlyworded, would interfere with the core refueling activities for the Unit 4 Cycle 27 RefuelingOutage scheduled for later this fall.2.0 Background InformationOn June 23, 2011, the NRC issued Amendment Nos. 244 to DPR-31 and 240 to DPR-41with supporting Safety Evaluation Report (SER) regarding the Alternative Source Term(AST) [Reference 1]. During site review of the TS for implementation, it was noted that**footnote at the bottom of TS page 3/4 7-16a had not being carried over and annotatedagainst TS 3.7.5 Action "c" for Modes 5 and 6 at the top of the following TS page 3/4 7-16b. It was further noted that **footnote only addresses "movement of irradiated fuel"and not "core alterations" or "positive reactivity changes." Therefore, Action "c", ascurrently worded, would prevent offload of the core at the commencement of the Unit 4Cycle 27 refueling outage if CREVS is considered inoperable (or the plant is in long termaction statements). Currently, Turkey Point is in Actions a.8 and a.9 with the kitchen areaand toilet motor-operated exhaust dampers closed and both exhaust ducts blanked offpending further design review.The existing **footnote acknowledges that when an action specified in Actions a.4, a.6,a.7, a.8, or a.9 is taken and the system (CREVS) is placed into the recirculation mode, theability of the affected (inoperable) component to perform its safety function has beenprovisionally restored, i.e., CREVS is fully functional. Therefore, the prohibition againstfuel movement in Modes 1-4 is no longer applicable.Similarly, this footnote when applied to TS 3.7.5 Action "c" is intended to acknowledgethat when an action specified in Actions a.4, a.6, a.7, a.8, or a.9 is taken and the system(CREVS) is placed into the recirculation mode, the ability of the affected (inoperable)component to perform its safety function has been provisionally restored, i.e., CREVS isfully functional. Although the footnote does require some minor revision to reflect theModes 5-6 action statement, the conclusion is unchanged. The prohibition against corealterations, movement of irradiated fuel in spent fuel pool, or positive reactivity changes inModes 5-6 is no longer applicable.The amendments proposed here will apply a ++footnote to TS 3.7.5 Action "c" that isbased on the **footnote but modified to include core alterations and positive reactivitychanges. The TS change will allow a resumption of core alterations, movement ofirradiated fuel in the spent fuel pool, and positive reactivity changes in Modes 5 and 6 ifactions have been taken that permit indefinite operation, i.e., make CREVS functional,and CREVS has been placed in recirculation mode.

Turkey Point Units 3 and 4 L-2012-313Docket Nos. 50-250 and 50-251 EnclosurePage 4 of 10This is consistent with the intent of FPL RAI response letters L-2010-083 dated 5/21/2010,L-2010-197 dated 9/15/2010, and L-2011-185 dated 5/11/2011 [References 3, 4, and 5].3.0 Description of Proposed ChangesThe proposed TS change involves TS 3.7.5 Action "c" only. In order to provide a morespecific description of the proposed change, a TS mark-up is attached and a description isprovided below with a brief justification.4.0 Basis/Justification for the Proposed Changes4.1 Changes to the PTN Technical Specifications4.1.1 Technical Specification 3.7.5 Action "c".Current TSc. With the Control Room Emergency Ventilation System inoperable,immediately suspend all operations involving CORE ALTERATIONS,movement of irradiated fuel in the spent fuel pool, or positive reactivitychanges. This ACTION shall apply to both units simultaneously.Proposed TSc. With the Control Room Emergency Ventilation System inoperable",immediately suspend all operations involving CORE ALTERATIONS,movement of irradiated fuel in the spent fuel pool, or positive reactivitychanges. This ACTION shall apply to both units simultaneously.++If action per ACTIONS a.4, a.6, a.7, a.8, or a.9 is taken such that indefiniteoperation is permitted and the system is placed in recirculation mode, thenCORE ALTERATIONS, movement of irradiated fuel in the spent fuel pool,or positive reactivity changes may resume.Basis for the Change: The **footnote annotated in Actions a.4, a.6, a.7, a.8, and a.9on TS page 3/4 7-16a that allows for the movement of irradiated fuel, when thespecified action has been taken permitting indefinite operation and CREVS has beenplaced in recirculation mode, was intended to address not only fuel movement in thespent fuel pool in Modes 1-4 but also refueling activities in both the containment andthe spent fuel pool in Modes 5 and 6.The inclusion of core alterations and positive reactivity changes in the ++footnote forTS 3.7.5 Action "c" in Modes 5-6 is consistent with the intent of the **footnote forModes 1-4 that allows fuel movement while CREVS is in a long-term action but stillable to provide its required licensing/design basis function. The annotation of themodified ++footnote to TS 3.7.5 Action "c" is required to assure the plant's ability tooffload and load fuel. TS 3.7.5 Action "c", as currently worded, would prevent theoffload of the core at the commencement of the Unit 4 Cycle 27 refueling outage ifTurkey Point is in a long term action, e.g., a.8 and a.9, as expected for the kitchenarea and toilet exhaust dampers noting that the motor-operated dampers are closedand both exhaust ducts are blanked off pending further design review.A markup of the proposed TS change is attached.

Turkey Point Units 3 and 4 L-2012-313Docket Nos. 50-250 and 50-251 EnclosurePage 5 of 105.0 List of CommitmentsNone6.0 ConclusionThe proposed amendments correct a clerical error identified in the issued TS involving TS3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote. The footnote forModes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positivereactivity changes as well as fuel movement in order to be consistent with the intent of theFPL responses to the NRC RAIs regarding AST and the CREVS. If not corrected, TS 3.7.5Action "c", as currently worded, would interfere with the core refueling activities for Unit 4Cycle 27 Refueling Outage scheduled for later this fall.7.0 No Significant Hazards DeterminationThe Commission has provided standards in 10 CFR 50.92(c) for determining whether asignificant hazards consideration exists. A proposed amendment to an operating licensefor a facility involves no significant hazard if operation of the facility in accordance withthe proposed amendment would not: (1) involve a significant increase in the probabilityor consequences of an accident previously evaluated; or (2) create the possibility of a newor different kind of accident from any accident previously evaluated; or (3) involve asignificant reduction in a margin of safety.The proposed license amendments to Renewed Facility Operating Licenses DPR-31 forTurkey Point Unit 3 and DPR-41 for Turkey Point Unit 4 will correct a clerical erroridentified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6 that omitted anapplicable footnote. The footnote for Modes 1-4 also needs to be modified for Modes 5-6 toinclude core alterations and positive reactivity changes as well as fuel movement in order tobe consistent with the intent of the FPL responses to the NRC RAIs regarding AST and theCREVS. If not corrected, TS 3.7.5 Action "c", as currently worded, could interfere withcore refueling activities for Unit 4 Cycle 27 Refueling Outage scheduled for later this fall.FPL has reviewed this proposed license amendment for FPL's Turkey Point Units 3 and 4and determined that its adoption would not involve a significant hazards consideration.The bases for this determination are:The proposed amendment does not involve a significant hazards consideration forthe following reasons:1. Does the proposed amendment involve a significant increase in the probabilityor consequences of an accident previously evaluated?No. The proposed amendments do not change or modify the fuel, fuel handlingprocesses, fuel storage racks, number of fuel assemblies that may be stored in the spentfuel pool (SFP), decay heat generation rate, or the spent fuel pool cooling and cleanupsystem. The proposed TS change will allow core alterations, fuel movement, andpositive reactivity changes in Modes 5 and 6 subject to the conditions specified in the++footnote that actions have been taken to permit indefinite system/component operationand the system is in recirculation mode. The proposed change corrects a clerical error byannotating TS 3.7.5 Action "c" with a modified footnote consistent with the stated intent Turkey Point Units 3 and 4 L-2012-313Docket Nos. 50-250 and 50-251 EnclosurePage 6 of 10of the original license submittals. The proposed amendments do not cause any physicalchange to the existing spent fuel storage configuration or fuel makeup. The proposedamendments do not affect any precursors to any accident previously evaluated or do notaffect any known mitigation equipment or strategies.Therefore, the proposed changes do not involve a significant increase in theprobability or consequences of an accident previously evaluated.2. Does the proposed amendment create the possibility of a new or different kind ofaccident from any accident previously evaluated?No. The proposed amendments do not change or modify the fuel, fuel handlingprocesses, fuel racks, number of fuel assemblies that may be stored in the pool, decayheat generation rate, or the spent fuel pool cooling and cleanup system. The proposedTS change will allow core alterations, fuel movement, and positive reactivity changesin Modes 5 and 6 subject to the conditions specified in the ++footnote that actions havebeen taken to permit indefinite system/component operation and the system is inrecirculation mode. The proposed change corrects a clerical error by annotating TS3.7.5 Action "c" with a modified footnote consistent with the stated intent of theoriginal license submittals.Therefore, the proposed changes do not create the possibility of a new or differentkind of accident from any accident previously evaluated.3. Does the proposed amendment involve a significant reduction in the margin ofsafety?No. The proposed amendments do not change or modify the fuel, fuel handlingprocesses, fuel racks, number of fuel assemblies that may be stored in the pool, decayheat generation rate, or the spent fuel pool cooling and cleanup system. Therefore, theproposed amendments have no impact to the existing margin of safety for subcriticalityrequired by 10 CFR 50.68 (b)(4).Therefore, the proposed amendments do not involve a significant reduction in themargin of safety.Based on the above discussion, FPL has determined that the proposed change does notinvolve a significant hazards consideration.8.0 Environmental Consideration10 CFR 51.22(c)(9) provides criteria for and identification of licensing and regulatoryactions eligible for categorical exclusion from performing an environmental assessment.A proposed amendment of an operating license for a facility requires no environmentalassessment, if the operation of the facility in accordance with the proposed amendmentdoes not: (1) involve a significant hazards consideration, (2) result in a significant changein the types or significant increase in the amounts of any effluents that may be releasedoffsite, and (3) result in a significant increase in individual or cumulative occupationalradiation exposure. FPL has reviewed this LAR and determined that the proposedamendments meet the eligibility criteria for categorical exclusion set forth in10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement Turkey Point Units 3 and 4 L-2012-313Docket Nos. 50-250 and 50-251 EnclosurePage 7 of 10or environmental assessment needs to be prepared in connection with the issuance of thisamendment. The basis for this determination follows.BasisThis change meets the eligibility criteria for categorical exclusion set forth in10 CFR 51.22(c)(9) for the following reasons:1. As demonstrated in the 10 CFR 50.92 evaluation, the proposed amendment does notinvolve a significant hazards consideration.2. The proposed amendment does not result in a significant change in the types or increasein the amounts of any effluents that may be released offsite. The proposed amendmentsdo not change or modify the fuel, fuel handling processes, fuel racks, number of fuelassemblies that may be stored in the pool, decay heat generation rate, or the spent fuelpool cooling and cleanup system. The proposed amendments do not change the designor operation of the spent fuel or spent fuel storage system. The proposed amendmentsdo not directly or indirectly affect effluent discharges.3. The proposed amendment does not result in a significant increase in individual orcumulative occupational radiation exposure. The proposed amendments do not changeor modify the fuel, fuel handling processes, fuel racks, number of fuel assemblies thatmay be stored in the pool, decay heat generation rate, or the spent fuel pool cooling andcleanup system. The proposed amendments do not change the design or operation ofthe spent fuel or spent fuel storage system. The proposed amendments do not directlyor indirectly affect the radiological source terms.9.0 Summary of ResultsThe proposed amendments correct a clerical error identified in the issued TS involving TS3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote. The footnote forModes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positivereactivity changes as well as fuel movement in order to be consistent with the intent of theFPL responses to the NRC RAIs regarding AST and the CREVS. If not corrected, TS 3.7.5Action "c", as currently worded, would interfere with the core refueling activities for Unit 4Cycle 27 Refueling Outage scheduled for later this fall.10.0 References1. J.
