The proposed change revises or adds Surveillance Requirements to verify that the systemlocations susceptible to gas accumulation are sufficiently filled with water and to provideallowances which permit performance of the verification.
The changes are being made toaddress the concerns discussed in NRC Generic Letter (GL) 2008-01, "Managing GasAccumulation in Emergency Core Cooling, Decay Heat Removal, and Containment SpraySystems,"
[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, GenericLetter 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 staffsevaluation, 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 andthe model safety evaluation prepared by the NRC staff are applicable to Turkey Point Units 3and 4 (Turkey Point) and justify this amendment for incorporation of the changes to the TurkeyPoint 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 PointStandard Technical Specifications Technical Specifications Westinglhouse Plants3.4.6, RCS LOOPS -Mode 4 3/4.4.1.3, Reactor Coolant System -HotShutdown3.4.7, RCS LOOPS -Mode 5 Loops Filled 3/4.4.1.4.1, Reactor Coolant System -ColdShutdown

-Low Water 3/4.9.8.2, Residual Heat Removal and CoolantLevel Circulation
-Low Water LevelThese differences are administrative and do not affect the applicability of TSTF-523 to TurkeyPoint. Attachment 3 provides revised (clean) TS pages.TSTF-523 and the model safety evaluation discuss the applicable regulatory requirements andguidance including the10 CFR 50, Appendix A, General Design Criteria (GDC). Turkey Pointwas not licensed to the 10 CFR 50, Appendix A, GDC. The Turkey Point design criteria arediscussed in the Updated Final Safety Analysis Report (UFSAR) Section 1.3, General DesignCriteria.
The Turkey Point design criteria that equates to GDC 1 are addressed in UFSARSection 1.3.1, Overall Requirements and the design criteria that equates to GDC 34 throughGDC 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 and4.3.0 REGULATORY SAFETY ANALYSIS3.1 No Significant Hazards Consideration Determination Florida Power & Light Company (FPL) requests adoption of Technical Specification Task ForceTraveler (TSTF)-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation,"
whichis an approved change to the standard technical specifications (STS), into the Turkey PointUnits 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 aresufficiently filled with water and to provide allowances which permit performance of theverification.
FPL has evaluated whether or not a significant hazards consideration is involved with theproposed 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 orConsequences of an Accident Previously Evaluated?
Response:
NoThe proposed change revises or adds SRs that require verification that the Emergency CoreCooling Systems (ECCS), the Residual Heat Removal (RHR) System, and the Containment Spray (CS) System are not rendered inoperable due to accumulated gas and to providePage 3 of 5 L-2014-028 Attachment 1allowances which permit performance of the revised verification.
Gas accumulation in thesubject systems is not an initiator of any accident previously evaluated.
As a result, theprobability of any accident previously evaluated is not significantly increased.
The proposedSRs ensure that the subject systems continue to be capable to perform their assumedsafety function and are not rendered inoperable due to gas accumulation.
Thus, theconsequences of any accident previously evaluated are not significantly increased.
Therefore, the proposed change does not involve a significant increase in the probability orconsequences of an accident previously evaluated.
: 2. Does the Proposed Change Create the Possibility of a New or Different Kind of Accidentfrom any Accident Previously Evaluated?
Response:
NoThe proposed change revises or adds SRs that require verification that the ECCS, the RHRSystem, and the CS System are not rendered inoperable due to accumulated gas and toprovide allowances which permit performance of the revised verification.
The proposedchange does not involve a physical alteration of the plant (i.e., no new or different type ofequipment 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 thatcould initiate an accident.
The proposed change does not alter assumptions made in thesafety analysis and is consistent with the safety analysis assumptions.
Therefore, the proposed change does not create the possibility of a new or different kind ofaccident from any accident previously evaluated.
: 3. Does the Proposed Change Involve a Significant Reduction in a Margin of Safety?Response:
NoThe proposed change revises or adds SRs that require verification that the ECCS, RHRSystem, and CS System are not rendered inoperable due to accumulated gas and toprovide allowances which permit performance of the revised verification.
The proposedchange adds new requirements to manage gas accumulation in order to ensure that thesubject systems are capable of performing their assumed safety functions.
The proposedSRs are more comprehensive than the current SRs and will ensure that the assumptions ofthe safety analysis are protected.
The proposed change does not adversely affect anycurrent plant safety margins or the reliability of the equipment assumed in the safetyanalysis.
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 aresult of the proposed change.Therefore, the proposed change does not involve a significant reduction in a margin ofsafety.Page 4 of 5 L-2014-028 Attachment 13.2 Applicable Regulatory Requirements/Criteria Based on the above, FPL concludes that the proposed change presents no significant hazardsconsideration 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 facilitycomponent located within the restricted area, as defined in 10 CFR Part 20, or would change aninspection or surveillance requirement.
: However, the proposed change does not involve (i) asignificant hazards consideration, (ii) a significant change in the types or significant increase inthe amounts of any effluent that may be released
: offsite, or (iii) a significant increase inindividual or cumulative occupational radiation exposure.
Accordingly, the proposed changemeets 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 hours forsurveillance testing to establish operability.
This is required because ofthe piping arrangement when the RHR system is being used for DecayHeat Removal.< 1INSERT 1 next page]3/4.4.2 Safety ValvesThe Pressurizer Code Safety Valves operate to prevent the RCS frombeing pressurized above its Safety Limit of 2735 psig. Each safetyvalve is designed to relieve 293,330 lbs per hour of saturated steam atthe valve setpoint.
The relief capacity of a single safety valve isadequate to relieve any overpressure condition which could occurduring shutdown.
In the event that NO safety valves are OPERABLE, an RCS vent opening of at least 2.20 square inches will provideoverpressure relief capability and will prevent RCS overpressurization.
In addition, the Overpressure Mitigating System provides a diversemeans of protection against RCS overpressurization at lowtemperatures.
During operation, all Pressurizer Code Safety Valves must beOPERABLE to prevent the RCS from being pressurized above itsSafety Limit of 2735 psig. The combined relief capacity of all of thesevalves is greater than the maximum surge rate resulting from acomplete loss-of-load assuming NO Reactor trip until the first ReactorTrip System Trip Setpoint is reached (i.e., NO credit is taken for adirect Reactor trip on the loss-of-load) and also assuming NOoperation of the power-operated relief valves or steam dump valves.The pressurizer safety valves are set to open at an RCS pressure of2465 psig +2% and -3% to avoid exceeding the maximum designpressure safety limit and to maintain accident assumptions.
Thepressurizer safety valve lift setting is needed to assure acceptable results for the Loss of Load/ Turbine Trip analysis.
The upper andlower 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 ofentrained gases. Preventing and managing gas intrusion and accumulation is necessary forproper 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 ofsystem design information, including piping and instrument
: drawings, isometric
: drawings, planand elevation
: drawings, and calculations.
The design review is supplemented by systemwalk downs to validate the system high points and to confirm the location and orientation ofimportant components that can become sources of gas or could otherwise cause gas to betrapped 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 areestablished for the volume of accumulated gas at susceptible locations.
If accumulated gas isdiscovered that exceeds the acceptance criteria for the susceptible location (or the volume ofaccumulated gas at one or more susceptible locations exceeds an acceptance criteria for gasvolume at the suction or discharge of a pump), the Surveillance is not met. If it is determined bysubsequent 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, thegas volume is compared to the acceptance criteria for the location.
Susceptible locations in thesame system flow path which are subject to the same gas intrusion mechanisms may beverified by monitoring a representative sub-set of susceptible locations.
Monitoring may not bepractical for locations that are inaccessible due to radiological or environmental conditions, the plantconfiguration, or personnel safety. For these locations, alternative methods (e.g., operating parameters, remote monitoring) may be used to monitor the susceptible location.
Monitoring isnot required for susceptible locations where the maximum potential accumulated gas voidvolume has been evaluated and determined to not challenge system OPERABILITY.
Theaccuracy of the method used for monitoring the susceptible locations and trending of the resultsshould 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 until12 hours after entering MODE 4. In a rapid shutdown, there may be insufficient time to verify allsusceptible locations prior to entering MODE 4.The 31 day frequency for ensuring locations are sufficiently filled with water takes intoconsideration the gradual nature of gas accumulation in the RHR System piping and theprocedural controls governing system operation.

3/4.5.3 ECCS Subsystems The OPERABILITY of ECCS components and flowpaths required inModes 1, 2 and 3 ensures that sufficient emergency core cooling capability will be available in the event of a LOGA assuming any single active failureconsideration.
Two SI Pumps and one RHR Pump operating in conjunctionL with two Accumulators are capable of supplying sufficient core cooling tou!limit the peak cladding temperatures within acceptable limits for all pipebreak sizes up to and including the maximum hypothetical accident of acircumferential rupture of a reactor coolant loop. In addition, the RHRsubsystem provides long-term core cooling capability in the recirculation mode during the accident recovery period.CAUTIONInterim Compensatory MeasureThe provision for temporary restoration of power to locked EGGS valves listedin SR 4.5.2.a for up to 24 hours to permit temporary operation for surveillance and maintenance purposes has been determined to be non-conservative withrespect to the safety analysis.
Therefore, until appropriate changes to SR 4.5.2via LAR 212 are approved and implemented, restoration of power to the valveslisted in SR 4.5.2.a shall be limited to one hour in order to provide alternative valve position indication in the event that the continuous valve positionindication (amber light) in the control room is unavailable.

Reference AR 1811016.Technical Specifications Surveillance Requirement 4.5.2.e.3 requires thateach EGGS component and flow path be demonstrated OPERABLE every18 months by visual inspection which verifies sump components (trashracks, screens, etc.) show NO evidence of structural distress or abnormalcorrosion.
The strainer modules are rigid enough to provide both functions as trash racks and screens without losing their structural integrity andparticle efficiency.
Therefore, strainer modules are functionally equivalent to trash racks and screens.
Accordingly, the categorical description, sumpcomponents, is broad enough to require inspection of the strainer modules.

The allowable out-of-service time requirements for the Containment Spray System have been maintained consistent with that assignedother inoperable ESF equipment and do NOT reflect the additional redundancy in cooling capability provided by the Emergency Containment Cooling System. Pump performance requirements areobtained from the accidents analysis assumptions.
Motor Operated Valves (MOVs) 862A, 862B, 863A, 863B are requiredto take suction from the Containment Sump via the RHR system.PC-600 supplies controlling signals to valves MOVs 862B and 863B, toprevent opening these valves if RHR pump B discharge pressure isabove 210 psig. PC-601 provides similar functions to valves MOVs862A and 863A. Although all four valves are normally locked inposition, with power removed, the capability to power up and stroke thevalves must be maintained in order to satisfy the requirements forOPERABLE flow paths (capable of taking suction from the containment sump).When PC-600/-601 are calibrated, a test signal is supplied to eachcircuit to check operation of the relays and annunciators operated bysubject controllers.

The requirement to have two RHR loops OPERABLE when there isless than 23 feet of water above the reactor vessel flange ensures thata single failure of the operating RHR loop will NOT result in a completeloss of residual heat removal capability.
With the reactor vessel headINSERT 4 removed and at least 23 feet of water above the reactor pressurenSet page vessel flange, a large heat sink is available for core cooling.

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 sequencebegins with control rod unlatching, followed by removal of upperinternals, followed by unloading fuel assemblies to the SFP. The corereload sequence consists of reloading fuel assemblies from the SFP,followed by upper internals installation, followed by latching controlrods. Therefore, if the Containment Ventilation Isolation System isdemonstrated OPERABLE at least once per 7 days following thespecified testing within 100 hours prior to the start of control rodunlatching, then Containment Ventilation Isolation System operability need NOT be demonstrated within 100 hours prior to the start of corereload. Otherwise, the specified testing is required to be performed within 100 hours prior to the start of core reload.
