(1) J. Paige (NRC) to M. Nazar (FPL), "Turkey Point Units 3 and 4 -"Issuance of Amendments Regarding 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. 244 and 240 to Renewed Facility Operating License Nos. DPR-31 and DPR-41 for the Turkey Point Nuclear 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 to address a clerical error identified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote.
The footnote for Modes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positive reactivity changes as well as fuel movement in order to be consistent 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, TS 3.7.5 Action "c", as currently worded, could interfere with core refueling activities for the Unit 4 Cycle 27 Refueling Outage scheduled for later this fall.Description of the proposed TS change with supporting justification and a no significant hazards determination and environmental consideration are provided in the Enclosure to this letter.The Turkey Point Plant Nuclear Safety Committee (PNSC) has reviewed the proposed license amendments.
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 not involve a significant hazards consideration.
FPL has determined that the proposed amendments involve no significant increase in the amounts or types of any effluents that may be released offsite, and no significant increase in individual or cumulative occupational radiation exposure.
Therefore, FPL has concluded that the proposed amendments 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 assessment need 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 to the onset of the Unit 4 Cycle 27 refueling outage scheduled to commence on November 5, 2012.Florida Power & Light Company 9760 SW 344 St., Florida City, FL 33035 142 0 X-(PL Turkey Point Nuclear Plant L-2012-313 Docket Nos. 50-250 and 50-251 Page 2 of 2 In accordance with 10 CFR 50.91(b)(1), a copy of this letter is being forwarded to the State Designee of Florida.Should you have any questions regarding this submittal, please contact Mr. Robert J. Tomonto, Licensing Manager, at (305) 246-7327.I declare under penalty of perjury that the foregoing is true and correct.Executed on August. 7 , 2012.Very truly yours, Michael Kiley Site Vice President Turkey Point Nuclear Plant Enclosure cc: USNRC Regional Administrator, Region II USNRC Project Manager, Turkey Point Nuclear Plant USNRC Senior Resident Inspector, Turkey Point Nuclear Plant Ms. Cindy Becker, Florida Department of Health Turkey Point Nuclear Plant Docket Nos. 50-250 and 50-251 L-2012-313 Enclosure Page 1 of 10 Enclosure Turkey Point Units 3 and 4 Administrative License Amendment Request No. 223 Regarding Control Room Emergency Ventilation System Technical Specification Turkey Point Units 3 and 4 L-2012-313 Docket Nos. 50-250 and 50-251 Enclosure Page 2 of 10 TABLE OF CONTENTS ADMINISTRATIVE LICENSE AMENDMENT REQUEST NO. 223 REGARDING CONTROL ROOM EMERGENCY VENTILATION SYSTEM TECHNICAL SPECIFICATION SECTION TITLE PAGE Cover Sheet 1--- Table of Contents 2 1.0 Purpose and Scope 3 2.0 Background Information 3 3.0 Description of Proposed Changes 4 4.0 Basis/Justification of Proposed Changes 4 5.0 List of Commitments 5 6.0 Conclusion 5 7.0 No Significant Hazards Determination 5 8.0 Environmental Consideration 6 9.0 Summary of Results 7 10.0 References 7 11.0 Tables & Figures 8 Turkey Point Units 3 and 4 L-2012-313 Docket Nos. 50-250 and 50-251 Enclosure Page 3 of 10 1.0 Purpose and Scope Florida Power and Light Company (FPL) proposes to amend Renewed Facility Operating Licenses DPR-31 and DPR-41 for Turkey Point Units 3 and 4 to correct a clerical error identified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote.
The footnote for Modes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positive reactivity changes as well as fuel movement in order to be consistent with the intent of the FPL responses to the NRC Requests for Additional Information (RAI) regarding the Alternative Source Term (AST) and the Control Room Emergency Ventilation System (CREVS). If not corrected, TS 3.7.5 Action "c", as currently worded, would interfere with the core refueling activities for the Unit 4 Cycle 27 Refueling Outage scheduled for later this fall.2.0 Background Information On June 23, 2011, the NRC issued Amendment Nos. 244 to DPR-31 and 240 to DPR-41 with 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 annotated against 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", as currently worded, would prevent offload of the core at the commencement of the Unit 4 Cycle 27 refueling outage if CREVS is considered inoperable (or the plant is in long term action statements).
Currently, Turkey Point is in Actions a.8 and a.9 with the kitchen area and toilet motor-operated exhaust dampers closed and both exhaust ducts blanked off pending 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, the ability of the affected (inoperable) component to perform its safety function has been provisionally restored, i.e., CREVS is fully functional.
Therefore, the prohibition against fuel movement in Modes 1-4 is no longer applicable.
Similarly, this footnote when applied to TS 3.7.5 Action "c" is intended to acknowledge 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, the ability of the affected (inoperable) component to perform its safety function has been provisionally restored, i.e., CREVS is fully functional.
Although the footnote does require some minor revision to reflect the Modes 5-6 action statement, the conclusion is unchanged.
The prohibition against core alterations, movement of irradiated fuel in spent fuel pool, or positive reactivity changes in Modes 5-6 is no longer applicable.
The amendments proposed here will apply a ++footnote to TS 3.7.5 Action "c" that is based on the **footnote but modified to include core alterations and positive reactivity changes. The TS change will allow a resumption of core alterations, movement of irradiated fuel in the spent fuel pool, and positive reactivity changes in Modes 5 and 6 if actions 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-2012-313 Docket Nos. 50-250 and 50-251 Enclosure Page 4 of 10 This 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 Changes The proposed TS change involves TS 3.7.5 Action "c" only. In order to provide a more specific description of the proposed change, a TS mark-up is attached and a description is provided below with a brief justification.
4.0 Basis/Justification for the Proposed Changes 4.1 Changes to the PTN Technical Specifications
 
====4.1.1 Technical====
 
Specification
 
====3.7.5 Action====
"c".Current TS c. 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 reactivity changes. This ACTION shall apply to both units simultaneously.
Proposed TS c. 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 reactivity changes. 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 indefinite operation is permitted and the system is placed in recirculation mode, then CORE 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.9 on TS page 3/4 7-16a that allows for the movement of irradiated fuel, when the specified action has been taken permitting indefinite operation and CREVS has been placed in recirculation mode, was intended to address not only fuel movement in the spent fuel pool in Modes 1-4 but also refueling activities in both the containment and the spent fuel pool in Modes 5 and 6.The inclusion of core alterations and positive reactivity changes in the ++footnote for TS 3.7.5 Action "c" in Modes 5-6 is consistent with the intent of the **footnote for Modes 1-4 that allows fuel movement while CREVS is in a long-term action but still able to provide its required licensing/design basis function.
The annotation of the modified ++footnote to TS 3.7.5 Action "c" is required to assure the plant's ability to offload and load fuel. TS 3.7.5 Action "c", as currently worded, would prevent the offload of the core at the commencement of the Unit 4 Cycle 27 refueling outage if Turkey Point is in a long term action, e.g., a.8 and a.9, as expected for the kitchen area and toilet exhaust dampers noting that the motor-operated dampers are closed and 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-2012-313 Docket Nos. 50-250 and 50-251 Enclosure Page 5 of 10 5.0 List of Commitments None 6.0 Conclusion The proposed amendments correct a clerical error identified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote.
The footnote for Modes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positive reactivity changes as well as fuel movement in order to be consistent with the intent of the FPL responses to the NRC RAIs regarding AST and the CREVS. If not corrected, TS 3.7.5 Action "c", as currently worded, would interfere with the core refueling activities for Unit 4 Cycle 27 Refueling Outage scheduled for later this fall.7.0 No Significant Hazards Determination The Commission has provided standards in 10 CFR 50.92(c) for determining whether a significant hazards consideration exists. A proposed amendment to an operating license for a facility involves no significant hazard if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.The proposed license amendments to Renewed Facility Operating Licenses DPR-31 for Turkey Point Unit 3 and DPR-41 for Turkey Point Unit 4 will correct a clerical error identified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote.
The footnote for Modes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positive reactivity changes as well as fuel movement in order to be consistent with the intent of the FPL responses to the NRC RAIs regarding AST and the CREVS. If not corrected, TS 3.7.5 Action "c", as currently worded, could interfere with core 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 4 and 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 for the following reasons: 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
No. The proposed amendments do not change or modify the fuel, fuel handling processes, fuel storage racks, number of fuel assemblies that may be stored in the spent fuel pool (SFP), decay heat generation rate, or the spent fuel pool cooling and cleanup system. The proposed TS change will allow core alterations, fuel movement, and positive 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 operation and the system is in recirculation mode. The proposed change corrects a clerical error by annotating TS 3.7.5 Action "c" with a modified footnote consistent with the stated intent Turkey Point Units 3 and 4 L-2012-313 Docket Nos. 50-250 and 50-251 Enclosure Page 6 of 10 of the original license submittals.
The proposed amendments do not cause any physical change to the existing spent fuel storage configuration or fuel makeup. The proposed amendments do not affect any precursors to any accident previously evaluated or do not affect any known mitigation equipment or strategies.
Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
: 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
No. The proposed amendments do not change or modify the fuel, fuel handling processes, fuel racks, number of fuel assemblies that may be stored in the pool, decay heat generation rate, or the spent fuel pool cooling and cleanup system. The proposed TS change will allow core alterations, fuel movement, and positive 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 operation and the system is in recirculation mode. The proposed change corrects a clerical error by annotating TS 3.7.5 Action "c" with a modified footnote consistent with the stated intent of the original license submittals.
Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
: 3. Does the proposed amendment involve a significant reduction in the margin of safety?No. The proposed amendments do not change or modify the fuel, fuel handling processes, fuel racks, number of fuel assemblies that may be stored in the pool, decay heat generation rate, or the spent fuel pool cooling and cleanup system. Therefore, the proposed amendments have no impact to the existing margin of safety for subcriticality required by 10 CFR 50.68 (b)(4).Therefore, the proposed amendments do not involve a significant reduction in the margin of safety.Based on the above discussion, FPL has determined that the proposed change does not involve a significant hazards consideration.
 
===8.0 Environmental===
 
Consideration 10 CFR 51.22(c)(9) provides criteria for and identification of licensing and regulatory actions eligible for categorical exclusion from performing an environmental assessment.
A proposed amendment of an operating license for a facility requires no environmental assessment, if the operation of the facility in accordance with the proposed amendment does not: (1) involve a significant hazards consideration, (2) result in a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, and (3) result in a significant increase in individual or cumulative occupational radiation exposure.
FPL has reviewed this LAR and determined that the proposed amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement Turkey Point Units 3 and 4 L-2012-313 Docket Nos. 50-250 and 50-251 Enclosure Page 7 of 10 or environmental assessment needs to be prepared in connection with the issuance of this amendment.
The basis for this determination follows.Basis This change meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) for the following reasons: 1. As demonstrated in the 10 CFR 50.92 evaluation, the proposed amendment does not involve a significant hazards consideration.
: 2. The proposed amendment does not result in a significant change in the types or increase in the amounts of any effluents that may be released offsite. The proposed amendments do not change or modify the fuel, fuel handling processes, fuel racks, number of fuel assemblies that may be stored in the pool, decay heat generation rate, or the spent fuel pool cooling and cleanup system. The proposed amendments do not change the design or operation of the spent fuel or spent fuel storage system. The proposed amendments do not directly or indirectly affect effluent discharges.
: 3. The proposed amendment does not result in a significant increase in individual or cumulative occupational radiation exposure.
The proposed amendments do not change or modify the fuel, fuel handling processes, fuel racks, number of fuel assemblies that may be stored in the pool, decay heat generation rate, or the spent fuel pool cooling and cleanup system. The proposed amendments do not change the design or operation of the spent fuel or spent fuel storage system. The proposed amendments do not directly or indirectly affect the radiological source terms.9.0 Summary of Results The proposed amendments correct a clerical error identified in the issued TS involving TS 3.7.5 Action "c" for Modes 5 and 6 that omitted an applicable footnote.
The footnote for Modes 1-4 also needs to be modified for Modes 5-6 to include core alterations and positive reactivity changes as well as fuel movement in order to be consistent with the intent of the FPL responses to the NRC RAIs regarding AST and the CREVS. If not corrected, TS 3.7.5 Action "c", as currently worded, would interfere with the core refueling activities for Unit 4 Cycle 27 Refueling Outage scheduled for later this fall.10.0 References
