1.0 DESCRIPTION

The proposed change revises or adds Surveillance Requirements to verify that the system locations susceptible to gas accumulation are sufficiently filled with water and to provide allowances which permit performance of the verification.

The changes are being made to address the concerns discussed in NRC Generic Letter (GL) 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," [Reference 2].The proposed amendment is consistent with Technical Specifications Task Force Traveler (TSTF)-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation" [Reference 3].2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Florida Power & Light Company (FPL) has reviewed the model safety evaluation published January 15, 2014 as part of the Federal Register Notice of Availability "TSTF-523, Generic Letter 2008-01 Managing Gas Accumulation Using the Consolidated Line Item Improvement Process" (79 FR 2700) [Reference 4]. This review included a review of the NRC staffs evaluation, as well as the information provided in TSTF-523.

As described in the subsequent paragraphs, FPL has concluded that the justifications presented in the TSTF-523 proposal and the model safety evaluation prepared by the NRC staff are applicable to Turkey Point Units 3 and 4 (Turkey Point) and justify this amendment for incorporation of the changes to the Turkey Point Technical Specifications (TS).2.2 Optional Changes and Variations FPL is proposing the following variations from the TS changes described in the TSTF-523, Revision 2 [Reference 3], or the applicable parts of the NRC staffs model safety evaluation.

The Turkey Point TS utilize different numbering, format, and titles than NUREG-1431, "Standard Technical Specifications -Westinghouse Plants" [Reference 5] on which TSTF-523 was based.Specifically, the numbering and titles differences are provided in the table below.NUREG-1431 Turkey Point Standard Technical Specifications Technical Specifications Westinglhouse Plants 3.4.6, RCS LOOPS -Mode 4 3/4.4.1.3, Reactor Coolant System -Hot Shutdown 3.4.7, RCS LOOPS -Mode 5 Loops Filled 3/4.4.1.4.1, Reactor Coolant System -Cold Shutdown -Loops Filled 3.4.8, RCS LOOPS -Mode 5 Loops Not Filled 3/4.4.1.4.2, Reactor Coolant System -Cold Shutdown -Loops Not Filled Page 2 of 5 L-2014-028 Attachment 1 NUREG-1431 Turkey Point Standard Technical Specifications Technical Specifications Westinghouse Plants 3.5.2, ECCS -Operating 3/4.5.2, ECCS Subsystems

-Tavg Greater than or Equal to 350°F 3.6.6A, Containment Spray and Cooling Systems 3/4.6.2, Containment Systems -Depressurization and Cooling Systems 3.9.5, RHR and Coolant Circulation

-High Water 3/4.9.8.1 ,Residual Heat Removal and Coolant Level Circulation

-High Water Level 3.9.6, RHR and Coolant Circulation

-Low Water 3/4.9.8.2, Residual Heat Removal and Coolant Level Circulation

-Low Water Level These differences are administrative and do not affect the applicability of TSTF-523 to Turkey Point. Attachment 3 provides revised (clean) TS pages.TSTF-523 and the model safety evaluation discuss the applicable regulatory requirements and guidance including the10 CFR 50, Appendix A, General Design Criteria (GDC). Turkey Point was not licensed to the 10 CFR 50, Appendix A, GDC. The Turkey Point design criteria are discussed in the Updated Final Safety Analysis Report (UFSAR) Section 1.3, General Design Criteria.

The Turkey Point design criteria that equates to GDC 1 are addressed in UFSAR Section 1.3.1, Overall Requirements and the design criteria that equates to GDC 34 through GDC 40 are addressed in UFSAR Section 1.3.7, Engineered Safety Features.

This difference does not alter the conclusion that the proposed change is applicable to Turkey Point Units 3 and 4.3.0 REGULATORY SAFETY ANALYSIS 3.1 No Significant Hazards Consideration Determination Florida Power & Light Company (FPL) requests adoption of Technical Specification Task Force Traveler (TSTF)-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation," which is an approved change to the standard technical specifications (STS), into the Turkey Point Units 3 and 4 Technical Specifications (TS). The proposed change revises or adds Surveillance Requirements (SRs) to verify that the system locations susceptible to gas accumulation are sufficiently filled with water and to provide allowances which permit performance of the verification.

FPL has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below: 1: Does the Proposed Change Involve a Significant Increase in the Probability or Consequences of an Accident Previously Evaluated?

Response:

No The proposed change revises or adds SRs that require verification that the Emergency Core Cooling Systems (ECCS), the Residual Heat Removal (RHR) System, and the Containment Spray (CS) System are not rendered inoperable due to accumulated gas and to provide Page 3 of 5 L-2014-028 Attachment 1 allowances which permit performance of the revised verification.

Gas accumulation in the subject systems is not an initiator of any accident previously evaluated.

As a result, the probability of any accident previously evaluated is not significantly increased.

The proposed SRs ensure that the subject systems continue to be capable to perform their assumed safety function and are not rendered inoperable due to gas accumulation.

Thus, the consequences of any accident previously evaluated are not significantly increased.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the Proposed Change Create the Possibility of a New or Different Kind of Accident from any Accident Previously Evaluated?

Response:

No The proposed change revises or adds SRs that require verification that the ECCS, the RHR System, and the CS System are not rendered inoperable due to accumulated gas and to provide allowances which permit performance of the revised verification.

The proposed change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operation.

In addition, the proposed change does not impose any new or different requirements that could initiate an accident.

The proposed change does not alter assumptions made in the safety analysis and is consistent with the safety analysis assumptions.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Does the Proposed Change Involve a Significant Reduction in a Margin of Safety?Response:

No The proposed change revises or adds SRs that require verification that the ECCS, RHR System, and CS System are not rendered inoperable due to accumulated gas and to provide allowances which permit performance of the revised verification.

The proposed change adds new requirements to manage gas accumulation in order to ensure that the subject systems are capable of performing their assumed safety functions.

The proposed SRs are more comprehensive than the current SRs and will ensure that the assumptions of the safety analysis are protected.

The proposed change does not adversely affect any current plant safety margins or the reliability of the equipment assumed in the safety analysis.

Therefore, there are no changes being made to any safety analysis assumptions, safety limits, or limiting safety system settings that would adversely affect plant safety as a result of the proposed change.Therefore, the proposed change does not involve a significant reduction in a margin of safety.Page 4 of 5 L-2014-028 Attachment 1 3.2 Applicable Regulatory Requirements/Criteria Based on the above, FPL concludes that the proposed change presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of"no significant hazards consideration" is substantiated.

4.0 ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR Part 20, or would change an inspection or surveillance requirement.

However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9).

Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

The Technical Specifications for Cold Shutdown allow an inoperable RHR pump to be the operating RHR pump 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 to establish operability.

This is required because of the piping arrangement when the RHR system is being used for Decay Heat Removal.< 1INSERT 1 next page]3/4.4.2 Safety Valves The Pressurizer Code Safety Valves operate to prevent the RCS from being pressurized above its Safety Limit of 2735 psig. Each safety valve is designed to relieve 293,330 lbs per hour of saturated steam at the valve setpoint.

The relief capacity of a single safety valve is adequate to relieve any overpressure condition which could occur during shutdown.

In the event that NO safety valves are OPERABLE, an RCS vent opening of at least 2.20 square inches will provide overpressure relief capability and will prevent RCS overpressurization.

In addition, the Overpressure Mitigating System provides a diverse means of protection against RCS overpressurization at low temperatures.

During operation, all Pressurizer Code Safety Valves must be OPERABLE to prevent the RCS from being pressurized above its Safety Limit of 2735 psig. The combined relief capacity of all of these valves is greater than the maximum surge rate resulting from a complete loss-of-load assuming NO Reactor trip until the first Reactor Trip System Trip Setpoint is reached (i.e., NO credit is taken for a direct Reactor trip on the loss-of-load) and also assuming NO operation of the power-operated relief valves or steam dump valves.The pressurizer safety valves are set to open at an RCS pressure of 2465 psig +2% and -3% to avoid exceeding the maximum design pressure safety limit and to maintain accident assumptions.

The pressurizer safety valve lift setting is needed to assure acceptable results for the Loss of Load/ Turbine Trip analysis.

The upper and lower pressure tolerance limits are based on the tolerance requirements assumed in the safety analyses.

RHR System piping and components have the potential to develop voids and pockets of entrained gases. Preventing and managing gas intrusion and accumulation is necessary for proper operation of the required RHR loops and may also prevent water hammer, pump cavitation, and pumping of non-condensible gas into the reactor vessel.Selection of RHR System locations susceptible to gas accumulation is based on a review of system design information, including piping and instrument drawings, isometric drawings, plan and elevation drawings, and calculations.

The design review is supplemented by system walk downs to validate the system high points and to confirm the location and orientation of important components that can become sources of gas or could otherwise cause gas to be trapped or difficult to remove during system maintenance or restoration.

Susceptible locations depend on plant and system configuration, such as stand-by versus operating conditions.

The RHR System is OPERABLE when it is sufficiently filled with water. Acceptance criteria are established for the volume of accumulated gas at susceptible locations.

If accumulated gas is discovered that exceeds the acceptance criteria for the susceptible location (or the volume of accumulated gas at one or more susceptible locations exceeds an acceptance criteria for gas volume at the suction or discharge of a pump), the Surveillance is not met. If it is determined by subsequent evaluation that the RHR System is not rendered inoperable by the accumulated gas (i.e., the system is sufficiently filled with water), the Surveillance may be declared met.Accumulated gas should be eliminated or brought within the acceptance criteria limits.RHR System locations susceptible to gas accumulation are monitored and, if gas is found, the gas volume is compared to the acceptance criteria for the location.

Susceptible locations in the same system flow path which are subject to the same gas intrusion mechanisms may be verified by monitoring a representative sub-set of susceptible locations.

Monitoring may not be practical for locations that are inaccessible due to radiological or environmental conditions, the plant configuration, or personnel safety. For these locations, alternative methods (e.g., operating parameters, remote monitoring) may be used to monitor the susceptible location.

Monitoring is not required for susceptible locations where the maximum potential accumulated gas void volume has been evaluated and determined to not challenge system OPERABILITY.

The accuracy of the method used for monitoring the susceptible locations and trending of the results should be sufficient to assure system OPERABILITY during the Surveillance interval.SR 4.4.1.3.4 is modified by a Note that states the SR is not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after entering MODE 4. In a rapid shutdown, there may be insufficient time to verify all susceptible locations prior to entering MODE 4.The 31 day frequency for ensuring locations are sufficiently filled with water takes into consideration the gradual nature of gas accumulation in the RHR System piping and the procedural controls governing system operation.

3/4.5.3 ECCS Subsystems The OPERABILITY of ECCS components and flowpaths required in Modes 1, 2 and 3 ensures that sufficient emergency core cooling capability will be available in the event of a LOGA assuming any single active failure consideration.

Two SI Pumps and one RHR Pump operating in conjunctionL with two Accumulators are capable of supplying sufficient core cooling to u!limit the peak cladding temperatures within acceptable limits for all pipe break sizes up to and including the maximum hypothetical accident of a circumferential rupture of a reactor coolant loop. In addition, the RHR subsystem provides long-term core cooling capability in the recirculation mode during the accident recovery period.CAUTION Interim Compensatory Measure The provision for temporary restoration of power to locked EGGS valves listed in SR 4.5.2.a for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to permit temporary operation for surveillance and maintenance purposes has been determined to be non-conservative with respect to the safety analysis.

Reference AR 1811016.Technical Specifications Surveillance Requirement 4.5.2.e.3 requires that each EGGS component and flow path be demonstrated OPERABLE every 18 months by visual inspection which verifies sump components (trash racks, screens, etc.) show NO evidence of structural distress or abnormal corrosion.

The strainer modules are rigid enough to provide both functions as trash racks and screens without losing their structural integrity and particle efficiency.

Therefore, strainer modules are functionally equivalent to trash racks and screens. Accordingly, the categorical description, sump components, is broad enough to require inspection of the strainer modules.

The administrative requirements for Special Reports are defined in Technical Specifications section 6.9.2.3/4.6.1.7 Containment Ventilation System The Containment Purge supply and exhaust isolation valves are required to be closed during a LOCA. When NOT purging, power to the purge valve actuators will be removed (sealed closed) to prevent inadvertent opening of these values. Maintaining these valves sealed closed during plant operation ensures that excessive quantities of radioactive materials will NOT be released via the Containment Purge System.Leakage integrity tests with a maximum allowable leakage rate for Containment Purge supply and exhaust supply valves will provide early indication of resilient material seal degradation and will allow opportunity for repair before gross leakage failures could develop. The 0.60 La leakage limit shall NOT be exceeded whenthe leakage rates determined by the leakage integrity tests of these valves are added to the previously determined total for all valves and penetrations subject to Type B and C tests.Management of gas voids is 3/4.6.2 Depressurization and Coolinq Systems important to containment spray system OPERABILITY.

3/4.6.2.1 Containment Spray System The OPERABILITY of the Containment Spray System ensures that containment depressurization capability will be available in the event of a LOCA. The pressure reduction and resultant lower containment leakage rate are consistent with the assumptions used in the safety analyses.

The allowable out-of-service time requirements for the Containment Spray System have been maintained consistent with that assigned other inoperable ESF equipment and do NOT reflect the additional redundancy in cooling capability provided by the Emergency Containment Cooling System. Pump performance requirements are obtained from the accidents analysis assumptions.

Motor Operated Valves (MOVs) 862A, 862B, 863A, 863B are required to take suction from the Containment Sump via the RHR system.PC-600 supplies controlling signals to valves MOVs 862B and 863B, to prevent opening these valves if RHR pump B discharge pressure is above 210 psig. PC-601 provides similar functions to valves MOVs 862A and 863A. Although all four valves are normally locked in position, with power removed, the capability to power up and stroke the valves must be maintained in order to satisfy the requirements for OPERABLE flow paths (capable of taking suction from the containment sump).When PC-600/-601 are calibrated, a test signal is supplied to each circuit to check operation of the relays and annunciators operated by subject controllers.

This test signal will prevent MOVs 862A, 862B, INSERT 3 863A, 863B from opening. Therefore, it is appropriate to tag out the next page MOV breakers, and enter Technical Specification Action Statement 3.5.2.a. and 3.6.2.1 when calibrating PC-600/-601.

3/4.6.2.2 Emerclencv Containment Coolina Svstem The OPERABILITY of the Emergency Containment Cooling (ECC)System ensures that the heat removal capacity is maintained with acceptable ranges following postulated design basis accidents.

To support both containment integrity safety analyses and component cooling water thermal analysis, a maximum of two ECCs can receive an automatic start signal following generation of a safety injection (SI)signal (one ECC receives an A train SI signal and another ECC receives a B train SI signal). To support post-LOCA long-term containment pressure/temperature analyses, a maximum of two ECCs are required to operate. The third (swing) ECC is required to be OPERABLE to support manual starting following a postulated LOCA event for containment pressure/temperature suppression.

INSERT 3 Containment Spray System piping and components have the potential to develop voids and pockets of entrained gases. Preventing and managing gas intrusion and accumulation is necessary for proper operation of the containment spray trains and may also prevent a water hammer and pump cavitation.

Selection of Containment Spray System locations susceptible to gas accumulation is based on a review of system design information, including piping and instrument drawings, isometric drawings, plan and elevation drawings, and calculations.

The design review is supplemented by system walk downs to validate the system high points and to confirm the location and orientation of important components that can become sources of gas or could otherwise cause gas to be trapped or difficult to remove during system maintenance or restoration.

Susceptible locations depend on plant and system configuration, such as stand-by versus operating conditions.

The Containment Spray System is OPERABLE when it is sufficiently filled with water.Acceptance criteria are established for the volume of accumulated gas at susceptible locations.

If accumulated gas is discovered that exceeds the acceptance criteria for the susceptible location (or the volume of accumulated gas at one or more susceptible locations exceeds an acceptance criteria for gas volume at the suction or discharge of a pump), the Surveillance is not met. If it is determined by subsequent evaluation that the Containment Spray System is not rendered inoperable by the accumulated gas (i.e., the system is sufficiently filled with water), the Surveillance may be declared met. Accumulated gas should be eliminated or brought within the acceptance criteria limits.Containment Spray System locations susceptible to gas accumulation are monitored and, if gas is found, the gas volume is compared to the acceptance criteria for the location.

Susceptible locations in the same system flow path which are subject to the same gas intrusion mechanisms may be verified by monitoring a representative sub-set of susceptible locations.

Monitoring may not be practical for locations that are inaccessible due to radiological or environmental conditions, the plant configuration, or personnel safety. For these locations, alternative methods (e.g., operating parameters, remote monitoring) may be used to monitor the susceptible location.

Monitoring is not required for susceptible locations where the maximum potential accumulated gas void volume has been evaluated and determined to not challenge system OPERABILITY.

The accuracy of the method used for monitoring the susceptible locations and trending of the results should be sufficient to assure system OPERABILITY during the Surveillance interval.The 31 day frequency for SR 4.6.2.1 .c takes into consideration the gradual nature of gas accumulation in the Containment Spray System piping and the procedural controls governing system operation.

SR 4.6.2.1 .a is modified by a Note which exempts system vent flow paths opened under administrative control. The administrative control should be proceduralized and include stationing a dedicated individual at the system vent flow path who is in continuous communication with the operators in the control room. This individual will have a method to rapidly close the system vent path if directed.

The requirement to have two RHR loops OPERABLE when there is less than 23 feet of water above the reactor vessel flange ensures that a single failure of the operating RHR loop will NOT result in a complete loss of residual heat removal capability.

With the reactor vessel head INSERT 4 removed and at least 23 feet of water above the reactor pressure nSet page vessel flange, a large heat sink is available for core cooling. Thus, in inext page the event of a failure of the operating RHR loop, adequate time is-provided to initiate emergency procedures to cool the core.3/4.9.9 Containment Ventilation Isolation System The OPERABILITY of this system ensures that the containment ventilation penetrations will be automatically isolated upon detection of high radiation levels within the containment.

The OPERABILITY of this system is required to restrict the release of radioactive material from the containment atmosphere to the environment.

T.S. surveillance requirement 4.9.9 states: 4.9.9 The Containment Ventilation Isolation System shall be demonstrated OPERABLE within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to the start of and at least once per 7 days during CORE ALTERATIONS by verifying that Containment Ventilation Isolation occurs on a High Radiation test signal from each of the containment radiation monitoring instrumentation channels.A normal refueling consists of 2 CORE ALTERATION sequences:

unloading the core, and reloading the core, typically with a suspension of CORE ALTERATIONS in between. The core unload sequence begins with control rod unlatching, followed by removal of upper internals, followed by unloading fuel assemblies to the SFP. The core reload sequence consists of reloading fuel assemblies from the SFP, followed by upper internals installation, followed by latching control rods. Therefore, if the Containment Ventilation Isolation System is demonstrated OPERABLE at least once per 7 days following the specified testing within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to the start of control rod unlatching, then Containment Ventilation Isolation System operability need NOT be demonstrated within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to the start of core reload. Otherwise, the specified testing is required to be performed within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to the start of core reload.
