Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 2.5.4.4 Ultimate Heat Sink 2.5.4.4.1 Regulatory Evaluation The ultimate heat sink (UHS) is the source of cooling water provided to dissipate reactor decay heat and essential cooling system heat loads after a normal reactor shutdown or a shutdown following an accident. FPLs review focused on the impact that the proposed EPU has on the decay heat removal capability of the UHS. Additionally, FPLs review included evaluation of the design-basis UHS temperature limit determination to confirm that post-licensing data trends (e.g.,
air and water temperatures, humidity, wind speed, water volume) do not establish more severe conditions than previously assumed.
The NRCs acceptance criteria for the UHS are based on:
- GDC-5, insofar as it requires that SSCs important to safety not be shared among nuclear power units unless it can be shown that sharing will not significantly impair their ability to perform their safety functions; and
- GDC-44, insofar as it requires that a system with the capability to transfer heat loads from safety-related SSCs to a heat sink under both normal operating and accident conditions be provided.
Specific review criteria are contained in SRP Section 9.2.5 and other guidance provided in Matrix 5 of RS-001.
Current Licensing Basis As noted in PTN Updated Final Safety Analysis Report (UFSAR), Section 1.3, the General Design Criteria (GDC) used during licensing of the Turkey Point Nuclear Plant predate those provided today in 10 CFR 50, Appendix A. The PTN GDCs were developed based on the 1967 Atomic Energy Commission Proposed General Design Criteria and are addressed in various sections of the UFSAR.
The PTN GDC applicable to the UHS and within the scope of the stated regulatory evaluation is as follows:
PTN GDC-4, Sharing of Systems: Reactor facilities may share systems or components if it can be shown that such sharing will not result in undue risk to the health and safety of the public.
(GDC-5)
The PTN systems provided to transfer heat from safety-related components to the UHS, i.e.,
closed cooling water canals, are the Component Cooling Water (CCW) System and the Intake Cooling Water (ICW) System. The site occupies an area approximately 2 miles wide by 5 miles long and includes 168 miles of earthen canals covering approximately 6100 acres (4370 acres of water surface). The average canal depth is 2.8 feet. The total water volume in the cooling canals is approximately 12,300 acre-feet (4 billion gallons). The canals receive heated condenser water at one end and supply cooled water at the other end for reuse. The discharge canal receives heated effluent from the plant and distributes the flow into 32 feeder canals. Water in the feeder canals flows south and discharges to a single collecting canal that distributes water to six return canals. Water in the return canals flows north to the plant intake. The entire water circuit, plant Turkey Point Units 3 and 4 EPU Licensing Report 2.5.4.4-1 Ultimate Heat Sink
Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 discharge back to plant intake, is 13.2 miles and takes approximately 44 hours1.833 days <br />0.262 weeks <br />0.0603 months <br />. The temperature rise across the plant, from intake to discharge, averages 15-30°F depending upon the unit, unit load, and various other factors. The average intake temperature is 2.5°F above the average ambient air temperature. The closed cooling water canal system is a shared heat sink that services Turkey Point Units 1, 2, 3 & 4.
The CCW System is the heat sink for the Residual Heat Removal (RHR) System, the Chemical and Volume Control System (CVCS), the Spent Fuel Pit Cooling System and various Reactor Coolant System (RCS) components. A separate CCW System is provided for each nuclear unit.
However, the CCW System provides cross-tie connections for CCW-supplied components that could serve both Turkey Point Units 3 and 4. These components include the safety injection pumps. These cross-tie connections are subject to design criteria involving minimum capacity requirements, unit intermix prohibitions, single active failure tolerance and passive failure isolation capability.
The ICW System provides the cooling water to the safety-related CCW Heat Exchangers as well as to the non-safety-related Turbine Plant Cooling Water (TPCW) Heat Exchangers. A separate ICW System is provided for each nuclear unit.
Although there is no specific PTN GDC analogous to GDC-44 on Cooling Water, the GDC requirements are addressed in the plant design. The Auxiliary Feedwater (AFW) System supplies cooling water to the steam generators at times when the normal feedwater systems are not available. The CCW and ICW Systems are discussed above. These cooling water systems transfer heat from safety-related SSCs to either the ultimate heat sink (cooling canals) in the cases of CCW and ICW Systems or to the atmosphere in the case of the AFW System The CCW system is designed with sufficient redundancy such that a single active failure will not prevent the system from accomplishing its support function of cooling safety related equipment.
The intake cooling water system provides sufficient redundancy so that at least one intake cooling water pump will continue to operate to handle heat loads from design basis accidents following a postulated single active failure. The AFW System is designed with sufficient mechanical and electrical redundancy such that the single failure of an active component, either in the AFW System or in a supporting system, can be accommodated without loss of the overall AFW System safety-related functions.
PTNs UHS and associated structures were evaluated for plant license renewal. System and system components, materials of construction, operating histories and programs used to manage aging effects are documented in NUREG-1759, Safety Evaluation Report (SER) Related to the License Renewal of the Turkey Point Nuclear Plant, Units 3 and 4, dated April 2002 and supplemented in May 2002. See SER Sections 2.4.2.4, 2.4.2.6, and 2.4.2.11. Although the earthen canals were identified as within the scope of license renewal, no aging management program was required while the associated intake and discharge structures cited the Systems and Structures Monitoring Program as appropriate to manage their identified aging effects.

Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 2.5.4.4.2 Technical Evaluation 2.5.4.4.2.1 Introduction The UHS at PTN is a closed-loop cooling canal system that accepts the rejected heat loads from the plants at one end (discharge) and returns cooled water at the opposite (intake) end. The closed-loop cooling water canal system is a shared heat sink that services Turkey Point Fossil Units 1 & 2, and Nuclear Units 3 & 4. The total volume of water in the cooling canals is approximately 12,300 acre-feet (4 billion gallons).
The ultimate heat sink provides water to the Intake Cooling Water (ICW) System via the Intake Structure. The Intake Structure is Seismic Class I to the extent that water is always available to the ICW System. The Intake Cooling Water System provides cooling water for heat removal from safety-related heat exchangers, including the Component Cooling Water heat exchangers which cool the Residual Heat Removal System. Refer to LR Section 2.5.4.2, Station Service Water System, for a description of the cooled components and the water users supplied by the Intake Cooling Water System.
The maximum cooling canal water temperature was assumed to vary seasonally throughout the year for cooldown analyses. Temperatures were adjusted from 92°F (spring/fall) to 97°F (summer) based on the season. See LR Section 2.8.4.4, Residual Heat Removal System which describes the cooldown scenarios using the Ultimate Heat Sink for heat rejection.
A maximum cooling water temperature of 100°F is used for the safety analyses which rely on the ultimate heat sink for heat removal. See LR Section 2.6.1, Primary Containment Functional Design which describes the postulated accident scenarios using the ultimate heat sink for heat rejection.
The closed-loop cooling canal is also used by the non-safety related Circulating Water System to provide cooling water for heat removal from the turbine cycle during normal plant power operations. Refer to LR Section 2.5.8.1, Circulating Water System.
2.5.4.4.2.2 Input Parameters, Assumptions, and Acceptance Criteria Assumptions The following Ultimate Heat Sink temperatures were assumed in RHR Cooldown and postulated accident analyses.

Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 Acceptance Criteria The ultimate heat sink shall remove the Design Basis Accident heat load with a maximum temperature of 100°F.
2.5.4.4.2.3 Description of Analyses and Evaluations The Ultimate Heat Sink was evaluated to ensure it is capable of performing its intended function of a reliable water supply and heat removal capacity for normal and accident conditions following EPU.
The Ultimate Heat Sink was evaluated for the circulating water discharge temperatures during EPU normal operation and initial normal cooldown. These effects were evaluated against the Florida Department of Environmental Protection National Pollutant Discharge Elimination System (NPDES) permit (FL0001562) limits for PTN in LR Section 2.5.8.1, Circulating Water System.
Additional evaluations related to the Ultimate Heat Sink are addressed in the following Licensing Report Sections:
- Intake Cooling Water discharge temperatures, heat loads, and flow rates to the cooling canal system - LR Section 2.5.4.2, Station Service Water System.
- Post-accident heat removal requirements - LR Section 2.6.1, Primary Containment Functional Design.
- Reactor cooldown requirements - LR Section 2.8.4.4, Residual Heat Removal System.
2.5.4.4.2.4 License Renewal Impact Evaluation Portions of the Ultimate Heat Sink are within the scope of License Renewal. EPU activities do not add any new components nor do they introduce any new functions for existing components that would change the license renewal system evaluation boundaries. The changes associated with the operation of the Ultimate Heat Sink at EPU conditions do not add any new or previously unevaluated materials to the system. System component internal and external environments remain within the parameters previously evaluated. Thus, no new aging effects requiring management are identified.
2.5.4.4.2.5 Results The Ultimate Heat Sink continues to meet its licensing, design, and performance capabilities at EPU conditions as evidenced by the evaluation results below.
General Design Criteria The evaluation of the Ultimate Heat Sink capabilities at EPU conditions demonstrates that PTN will continue to meet the current licensing basis with respect to the requirements of PTN GDC-4.
There will be no increase in the amount of water withdrawn as a result of the EPU project. The Ultimate Heat Sink contains sufficient volume to provide cooling water to both units under all normal, abnormal, and accident conditions. Therefore, the Ultimate Heat Sink continues to meet Turkey Point Units 3 and 4 EPU Licensing Report 2.5.4.4-4 Ultimate Heat Sink
Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 the design requirements with respect to sharing of systems and components in accordance with PTN licensing basis and PTN GDC-4.
Water Supply and Heat Removal Requirements The Ultimate Heat Sink will continue to provide the required water supply and heat sink capacity at EPU conditions; the Intake Cooling Water flow requirements for cooling of safety-related heat exchangers either do not change or decrease slightly. The maximum increase in cooled water temperature leaving the cooling canal system to return to the units is approximately 0.9°F, from 91.9°F to 92.8°F. The analysis results discussed in LR Section 2.8.4.4, Residual Heat Removal System and LR Section 2.6.1, Primary Containment Functional Design confirm that the Ultimate Heat Sink will continue to provide sufficient water supply and heat removal for cooldown and to mitigate the postulated accident scenarios.
The intake cooling water returned to the Ultimate Heat Sink from cooled components experiences a small temperature change at normal operating, cooldown, and accident conditions due to the EPU. During normal operation and normal cooldown, the intake cooling water discharge temperatures increase slightly and the time to cooldown the plant is extended. During accident conditions, the intake cooling water discharge temperatures continue to be bound by existing analyses and the system design parameters. The circulating water flow rates remain within the existing design rating of the pumps. The circulating water discharge temperature is expected to increase by approximately 4°F at EPU conditions. The effect of intake cooling water discharge temperature changes during normal operation, normal cooldown, and accident conditions at EPU is minimal due to the mixing of the intake cooling water with circulating water, screen wash, and storm drain flows at the Discharge Structure before the effluent is discharged to the cooling canals. The intake cooling water flow rate is insignificant when compared to the flow rate of the circulating water through the condenser.
The discharge of circulating water is governed by the Florida NPDES permit. As discussed in LR Section 2.5.8.1, Circulating Water System. The higher circulating water temperature during normal plant power generation has no impact on the current NPDES permit which does not limit the maximum discharge temperature, differential temperature across the condenser, or total discharge heat.
2.5.4.4.3 Conclusion FPL has assessed the effects of the proposed EPU on the UHS safety function, including the validation of the design-basis UHS temperature limit based on post-licensing data. Based on this information, FPL concludes that the proposed EPU will not compromise the design-basis safety function of the UHS, and that the UHS will continue to satisfy the requirements of the plants current licensing basis with regard to PTN GDC-4 following implementation of the proposed EPU.
Therefore, FPL finds the proposed EPU acceptable with respect to the UHS.

Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 2.5.4.4 Ultimate Heat Sink 2.5.4.4.1 Regulatory Evaluation The ultimate heat sink (UHS) is the source of cooling water provided to dissipate reactor decay heat and essential cooling system heat loads after a normal reactor shutdown or a shutdown following an accident. FPLs review focused on the impact that the proposed EPU has on the decay heat removal capability of the UHS. Additionally, FPLs review included evaluation of the design-basis UHS temperature limit determination to confirm that post-licensing data trends (e.g.,
air and water temperatures, humidity, wind speed, water volume) do not establish more severe conditions than previously assumed.
The NRCs acceptance criteria for the UHS are based on:
- GDC-5, insofar as it requires that SSCs important to safety not be shared among nuclear power units unless it can be shown that sharing will not significantly impair their ability to perform their safety functions; and
- GDC-44, insofar as it requires that a system with the capability to transfer heat loads from safety-related SSCs to a heat sink under both normal operating and accident conditions be provided.
Specific review criteria are contained in SRP Section 9.2.5 and other guidance provided in Matrix 5 of RS-001.
Current Licensing Basis As noted in PTN Updated Final Safety Analysis Report (UFSAR), Section 1.3, the General Design Criteria (GDC) used during licensing of the Turkey Point Nuclear Plant predate those provided today in 10 CFR 50, Appendix A. The PTN GDCs were developed based on the 1967 Atomic Energy Commission Proposed General Design Criteria and are addressed in various sections of the UFSAR.
The PTN GDC applicable to the UHS and within the scope of the stated regulatory evaluation is as follows:
PTN GDC-4, Sharing of Systems: Reactor facilities may share systems or components if it can be shown that such sharing will not result in undue risk to the health and safety of the public.
(GDC-5)
The PTN systems provided to transfer heat from safety-related components to the UHS, i.e.,
closed cooling water canals, are the Component Cooling Water (CCW) System and the Intake Cooling Water (ICW) System. The site occupies an area approximately 2 miles wide by 5 miles long and includes 168 miles of earthen canals covering approximately 6100 acres (4370 acres of water surface). The average canal depth is 2.8 feet. The total water volume in the cooling canals is approximately 12,300 acre-feet (4 billion gallons). The canals receive heated condenser water at one end and supply cooled water at the other end for reuse. The discharge canal receives heated effluent from the plant and distributes the flow into 32 feeder canals. Water in the feeder canals flows south and discharges to a single collecting canal that distributes water to six return canals. Water in the return canals flows north to the plant intake. The entire water circuit, plant Turkey Point Units 3 and 4 EPU Licensing Report 2.5.4.4-1 Ultimate Heat Sink
Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 discharge back to plant intake, is 13.2 miles and takes approximately 44 hours1.833 days <br />0.262 weeks <br />0.0603 months <br />. The temperature rise across the plant, from intake to discharge, averages 15-30°F depending upon the unit, unit load, and various other factors. The average intake temperature is 2.5°F above the average ambient air temperature. The closed cooling water canal system is a shared heat sink that services Turkey Point Units 1, 2, 3 & 4.
The CCW System is the heat sink for the Residual Heat Removal (RHR) System, the Chemical and Volume Control System (CVCS), the Spent Fuel Pit Cooling System and various Reactor Coolant System (RCS) components. A separate CCW System is provided for each nuclear unit.
However, the CCW System provides cross-tie connections for CCW-supplied components that could serve both Turkey Point Units 3 and 4. These components include the safety injection pumps. These cross-tie connections are subject to design criteria involving minimum capacity requirements, unit intermix prohibitions, single active failure tolerance and passive failure isolation capability.
The ICW System provides the cooling water to the safety-related CCW Heat Exchangers as well as to the non-safety-related Turbine Plant Cooling Water (TPCW) Heat Exchangers. A separate ICW System is provided for each nuclear unit.
Although there is no specific PTN GDC analogous to GDC-44 on Cooling Water, the GDC requirements are addressed in the plant design. The Auxiliary Feedwater (AFW) System supplies cooling water to the steam generators at times when the normal feedwater systems are not available. The CCW and ICW Systems are discussed above. These cooling water systems transfer heat from safety-related SSCs to either the ultimate heat sink (cooling canals) in the cases of CCW and ICW Systems or to the atmosphere in the case of the AFW System The CCW system is designed with sufficient redundancy such that a single active failure will not prevent the system from accomplishing its support function of cooling safety related equipment.
The intake cooling water system provides sufficient redundancy so that at least one intake cooling water pump will continue to operate to handle heat loads from design basis accidents following a postulated single active failure. The AFW System is designed with sufficient mechanical and electrical redundancy such that the single failure of an active component, either in the AFW System or in a supporting system, can be accommodated without loss of the overall AFW System safety-related functions.
PTNs UHS and associated structures were evaluated for plant license renewal. System and system components, materials of construction, operating histories and programs used to manage aging effects are documented in NUREG-1759, Safety Evaluation Report (SER) Related to the License Renewal of the Turkey Point Nuclear Plant, Units 3 and 4, dated April 2002 and supplemented in May 2002. See SER Sections 2.4.2.4, 2.4.2.6, and 2.4.2.11. Although the earthen canals were identified as within the scope of license renewal, no aging management program was required while the associated intake and discharge structures cited the Systems and Structures Monitoring Program as appropriate to manage their identified aging effects.

Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 2.5.4.4.2 Technical Evaluation 2.5.4.4.2.1 Introduction The UHS at PTN is a closed-loop cooling canal system that accepts the rejected heat loads from the plants at one end (discharge) and returns cooled water at the opposite (intake) end. The closed-loop cooling water canal system is a shared heat sink that services Turkey Point Fossil Units 1 & 2, and Nuclear Units 3 & 4. The total volume of water in the cooling canals is approximately 12,300 acre-feet (4 billion gallons).
The ultimate heat sink provides water to the Intake Cooling Water (ICW) System via the Intake Structure. The Intake Structure is Seismic Class I to the extent that water is always available to the ICW System. The Intake Cooling Water System provides cooling water for heat removal from safety-related heat exchangers, including the Component Cooling Water heat exchangers which cool the Residual Heat Removal System. Refer to LR Section 2.5.4.2, Station Service Water System, for a description of the cooled components and the water users supplied by the Intake Cooling Water System.
The maximum cooling canal water temperature was assumed to vary seasonally throughout the year for cooldown analyses. Temperatures were adjusted from 92°F (spring/fall) to 97°F (summer) based on the season. See LR Section 2.8.4.4, Residual Heat Removal System which describes the cooldown scenarios using the Ultimate Heat Sink for heat rejection.
A maximum cooling water temperature of 100°F is used for the safety analyses which rely on the ultimate heat sink for heat removal. See LR Section 2.6.1, Primary Containment Functional Design which describes the postulated accident scenarios using the ultimate heat sink for heat rejection.
The closed-loop cooling canal is also used by the non-safety related Circulating Water System to provide cooling water for heat removal from the turbine cycle during normal plant power operations. Refer to LR Section 2.5.8.1, Circulating Water System.
2.5.4.4.2.2 Input Parameters, Assumptions, and Acceptance Criteria Assumptions The following Ultimate Heat Sink temperatures were assumed in RHR Cooldown and postulated accident analyses.

2.5.4.4.2.3 Description of Analyses and Evaluations The Ultimate Heat Sink was evaluated to ensure it is capable of performing its intended function of a reliable water supply and heat removal capacity for normal and accident conditions following EPU.
The Ultimate Heat Sink was evaluated for the circulating water discharge temperatures during EPU normal operation and initial normal cooldown. These effects were evaluated against the Florida Department of Environmental Protection National Pollutant Discharge Elimination System (NPDES) permit (FL0001562) limits for PTN in LR Section 2.5.8.1, Circulating Water System.
Additional evaluations related to the Ultimate Heat Sink are addressed in the following Licensing Report Sections:
- Intake Cooling Water discharge temperatures, heat loads, and flow rates to the cooling canal system - LR Section 2.5.4.2, Station Service Water System.
- Post-accident heat removal requirements - LR Section 2.6.1, Primary Containment Functional Design.
- Reactor cooldown requirements - LR Section 2.8.4.4, Residual Heat Removal System.
2.5.4.4.2.4 License Renewal Impact Evaluation Portions of the Ultimate Heat Sink are within the scope of License Renewal. EPU activities do not add any new components nor do they introduce any new functions for existing components that would change the license renewal system evaluation boundaries. The changes associated with the operation of the Ultimate Heat Sink at EPU conditions do not add any new or previously unevaluated materials to the system. System component internal and external environments remain within the parameters previously evaluated. Thus, no new aging effects requiring management are identified.
2.5.4.4.2.5 Results The Ultimate Heat Sink continues to meet its licensing, design, and performance capabilities at EPU conditions as evidenced by the evaluation results below.
General Design Criteria The evaluation of the Ultimate Heat Sink capabilities at EPU conditions demonstrates that PTN will continue to meet the current licensing basis with respect to the requirements of PTN GDC-4.
There will be no increase in the amount of water withdrawn as a result of the EPU project. The Ultimate Heat Sink contains sufficient volume to provide cooling water to both units under all normal, abnormal, and accident conditions. Therefore, the Ultimate Heat Sink continues to meet Turkey Point Units 3 and 4 EPU Licensing Report 2.5.4.4-4 Ultimate Heat Sink
Turkey Point Units 3 and 4 L-2010-113 Docket Nos. 50-250 and 50-251 Attachment 4 the design requirements with respect to sharing of systems and components in accordance with PTN licensing basis and PTN GDC-4.
Water Supply and Heat Removal Requirements The Ultimate Heat Sink will continue to provide the required water supply and heat sink capacity at EPU conditions; the Intake Cooling Water flow requirements for cooling of safety-related heat exchangers either do not change or decrease slightly. The maximum increase in cooled water temperature leaving the cooling canal system to return to the units is approximately 0.9°F, from 91.9°F to 92.8°F. The analysis results discussed in LR Section 2.8.4.4, Residual Heat Removal System and LR Section 2.6.1, Primary Containment Functional Design confirm that the Ultimate Heat Sink will continue to provide sufficient water supply and heat removal for cooldown and to mitigate the postulated accident scenarios.
The intake cooling water returned to the Ultimate Heat Sink from cooled components experiences a small temperature change at normal operating, cooldown, and accident conditions due to the EPU. During normal operation and normal cooldown, the intake cooling water discharge temperatures increase slightly and the time to cooldown the plant is extended. During accident conditions, the intake cooling water discharge temperatures continue to be bound by existing analyses and the system design parameters. The circulating water flow rates remain within the existing design rating of the pumps. The circulating water discharge temperature is expected to increase by approximately 4°F at EPU conditions. The effect of intake cooling water discharge temperature changes during normal operation, normal cooldown, and accident conditions at EPU is minimal due to the mixing of the intake cooling water with circulating water, screen wash, and storm drain flows at the Discharge Structure before the effluent is discharged to the cooling canals. The intake cooling water flow rate is insignificant when compared to the flow rate of the circulating water through the condenser.
The discharge of circulating water is governed by the Florida NPDES permit. As discussed in LR Section 2.5.8.1, Circulating Water System. The higher circulating water temperature during normal plant power generation has no impact on the current NPDES permit which does not limit the maximum discharge temperature, differential temperature across the condenser, or total discharge heat.
2.5.4.4.3 Conclusion FPL has assessed the effects of the proposed EPU on the UHS safety function, including the validation of the design-basis UHS temperature limit based on post-licensing data. Based on this information, FPL concludes that the proposed EPU will not compromise the design-basis safety function of the UHS, and that the UHS will continue to satisfy the requirements of the plants current licensing basis with regard to PTN GDC-4 following implementation of the proposed EPU.
Therefore, FPL finds the proposed EPU acceptable with respect to the UHS.
