They are used to provide an audible indication of the neutron count rate in containment to the control room and to the operators in containment to prevent high personnel exposure during refueling operations.
The detectors also provide a reactor trip signal in the event of an excessively high startup rate.Calculation PTN-BFJF-91-01,"Neutron Source Requirements During Reload and Initial Criticality
-Turkey Point Units 3&4," demonstrated that the residual neutron production from fission product decay in the reloaded fuel alone provides a detector response sufficiently above background to monitor subcritical multiplication using the source range detectors.
The analysis considered a broad range of fuel initial enrichments, burnups, and decay times.Therefore, the refueling procedures for each unit will be revised to place fuel assemblies with sufficient neutron sources closest to the excore source range detectors to assure an adequate detector response during refueling operations.
The FSAR will be updated to reflect that the reloaded fuel will provide an adequate source of neutrons for future cycles.171 PLANT CHANGE MODIFICATION 91-043 Page 2 of 2 UNIT 4 REMOVAL OF STARTUP SOURCES Safet Evaluation:

186 SAFETY EVALUATXON:
JPE-LR-87-020 Revision 5 OPERATION WITH LOSS OF HVAC TO THE DC EQUIPMENT AND INVERTER ROOMS In 1986, Florida Power and Light (FPL)identified a concern related to the loss of HVAC in the DC Equipment/Inverter Rooms at Turkey Point Units 3&4.This evaluation indicates a maximum operability temperature of 135 degrees Fahrenheit is acceptable (except for the battery rooms where 115 degrees Fahrenheit is the acceptable maximum).Operation at or above this temperature for short periods of time (from a few days to months depending on the particular piece of equipment) does not introduce a failure mechanism.
This evaluation also reviewed the use of supplemental cooling and provided requirements that should be implemented to ensure detection and timely compensatory actions for any credible HVAC failure scenario and resulting temperature excursion in the DC Equipment/Inverter rooms.Safet Evaluation Summa The DC Equipment/Inverter Rooms'VAC systems are not addressed in the Turkey Point Technical Specifications; therefore, this evaluation has no effect on the plant's Technical Specifications.
Since no existing safety analyses are affected and no new failure modes are introduced, the use of supplemental cooling does not constitute an unreviewed safety question pursuant to 10 CFR 50.59.Therefore, prior NRC approval was not required.Revision 5 of this SE provides additional evaluations which justify a 60 minute delay for manually restarting certain HVAC loads after a Loss of Offsite Power (LOOP)event.Also, air flow rates used for the HVAC systems of the DC Equipment and Inverter Rooms have been updated based on post modification testing performed during the dual unit outage of 1990-1991.Issued: November 6, 1991 188 SAFETY EVALUATION:
JPN-PTN-SEMS-90-041 Revision 4 ACCEPTABILITY OF AS-FOUND CONDITION FOR RHR VALVE 3-753A The unit 3 Residual Heat Removal System{RHR)"A" Pump Discharge Check Valve 3-753A has been determined to have a 1 1/32" long by 1/16" wide linear indication the full distance across the valve seat and extending into the valve body.A flaw evaluation has been performed in accordance with general flaw evaluation methods contained in ASME Section XI.Safet Evaluation Summar Revision 0 to this evaluation showed that the continued use and operation of check valve 3-753A, in its as-found condition between March 1990, and the Dual Unit Outage did not affect any Technical Specifications, plant operation or safety, and that an unreviewed safety question did not exist.Revision 1 to this evaluation showed that, based on present flaw condition, continued use and operation of check valve 3-753A is acceptable for the remainder of Unit 3 Cycle 12{not including cycle 13 fuel load activities)
.Revision 2 to this evaluation included administrative changes, clarification to allowed operational durations and miscellaneous consistency changes.Revision 3 to this evaluation showed that continuous operation without reinspection of 3-753A is acceptable based on the calculated flaw growth to be small for more than 40 years.This effectively extends the acceptable operation period of the valve to the end-of-service life of the plant.Revision 4 removes the requirement for the re-inspection of check valve 3-753A at the first opportunity after January 1996, originally in Revision 3.Continued operation of valve 3-753A does not represent an operability concern, does not affect any Technical Specifications, plant operation or plant safety, and does not constitute an unreviewed safety question.Issued: June 26, 1992 189 SAFETY EVALUATION:
JPN-PTN-SEMS-90-066 Revision 0 REMOVAL OF TURBINE OVERSPEED TRIP LOWER RANGE VALUE FROM THE UFSAR Section 14.1.13 of the UFSAR and plant procedures require that the Mechanical Turbine Overspeed Trip stop all flow of steam into or through the turbine when the turbine speed has increased to the range of 1970 RPM to 1998 RPM (this corresponds to approximately 9 1/2%to 11%above normal speed).This Safety Evaluation addresses the elimination of the listed range of 1970 RPM from the UFSAR because the range is restrictive and can cause unnecessary plant delays during startup.The Safety Evaluation also provides the acceptable range of the trip values that should be maintained.
Safet Evaluation Summa The information presented in this safety evaluation demonstrates that the operational function of the Mechanical Turbine Overspeed Trip mechanism upper limit is the critical value and the elimination of the lower limit and the newly defined range as identified in the Safety Evaluation will not adversely effect plant safety or operations.
There are no new restrictions on plant operations pursuant to this evaluation.
Based on this evaluation, this change does not constitute an unreviewed safety question or a change to the plant Technical Specification pursuant to 10CFR50.59.

JPN-PTN-SEMJ-90-105 Revision 0 GENERIC LETTER 88-17: DEFEAT OF RHR SUCTION VALVES INTERLOCK DURING MID-LOOP OPERATIONS This safety evaluation addresses a recommendation in GL 88-17 to implement/revise procedures and administrative controls.These procedures and administrative controls are to avoid operations that can lead to perturbations to the RCS and/or systems that are necessary to maintain the RCS in a stable and controlled condition'hile the RCS is in a reduced inventory condition.
More specifically, this safety evaluation addresses preventing a spurious isolation of the RHR suction isolation valves MOV-"-750 and 751.This is to be accomplished by defeating the RCS high pressure interlock function of, these valves when in reduced inventory condition.
This interlock can lead to loss of RHR event and consequently to further reduction in RCS inventory'afet Evaluation Summa This safety evaluation shows that defeating the RHR interlocks associated with MOV-~-750 and MOV-*-751 while in modes 5 and 6 during reduced inventory operation prevents a spurious isolation of the RHR suction isolation valves MOV-*-750 and 751 and does not constitute an unreviewed

JPN-PTN-SEES-90-142 Revision 2 TEMPORARY INSTALLATION AND OPERATION OF SPARE NIS SOURCE RANGE DETECTORS This safety evaluation addresses the Temporary System Alteration
{TSA)that installs two spare source range detectors within the active region of the core which will be connected to the existing preamplifiers only in case of failure of either primary source range detector.This temporary installation and operation will supply spare monitoring capabilities.
The installation and operation of the spare detectors shall only be used during fuel movement operations (Mode 6)where the safety actuation function of the source range has been defeated.Safet Evaluation Summa As evaluated in this safety evaluation the implementation of the referenced TSA with the subsequent connection of the spare detector in case of single failure, does not change plant operation or safety, and does not create an unreviewed safety question or require a change to any Technical Specification.
Therefore, prior NRC approval is not required.Issued: September 4, 1991 192
SAFETY EVALUATION:
JPN-PTN-SENS-90-145 Revision 2 TEMPORARY LIQUID RADWASTE DISCHARGE HEADER MODIFICATION The scheduled work for Condenser and Intake Bay maintenance on Units 3 and 4 during the dual unit outage may result in a loss of all circulating water pumps for indeterminate periods of-time.The liquid ra'dwaste discharge header is interlocked with circulating water flow such that solenoid valves SV-*-1413 and SV-*-1414 will shut on loss of circulating water flow, terminating any liquid discharges.
A Temporary System Alteration (TSA 3-91-61-35) will be installed to bypass the solenoid valves and discharge liquids into the ICW pump discharge will for any time all Unit 3 and 4 circulating water pumps are inoperable.
This safety evaluation addresses the effects of bypassing the solenoid valves, and using ICW pump flow for effluent dilution instead of Unit 3 and 4 circulating water (CW)pump flow for calculating the pre-and post-release isotopic Maximum Permissible Concentrations (MPC).Safet Evaluation Summa This safety evaluation concluded that the temporary change did not require any changes to the Plant Technical Specifications, did not affect plant safety or operation, and did not constitute an unreviewed safety question pursuant to 10, CFR 50.59.Therefore, prior NRC approval was not required for implementation.

SAFETY EVALUATION JPN-PTN-SEIS-91-093 Revision 0 SAFETY EVALUATION FOR OVERTEMPERATURE (OT)AND OVERPOWER (OP)DELTA-T FOR TURBINE RUNBACK SETPOINT This safety evaluation addresses setting the Overtemperature Delta-T (OT Delta-T)and the Overpower Delta-T (OP Delta-T)turbine runback setpoints to a value below the recommended Delta-T setting of 2%power below the trip setpoints.
Setting the OT and OP turbine runback to a value below the typical recommended setting will provide assurance that the alarms from the OT Delta-T Rod Stop and the Auto turbine runback will be eliminated (reduced).The OT Delta-T and OP Delta-T turbine runback is intended to improve plant availability by assisting the operators in mitigating a transient to prevent a reactor trip and no credit is taken in any safety analysis.The setpoint chance impacts the operation of the turbine runback feature only when the rod control system is in manual for a limited number of slow developing transients.
Although the time window for effective operator action has been shortened, sufficient time to mitigate a transient still exists to avoid a reactor trip.Safet Evaluation Summa This safety evaluation concludes that the OT Delta-T and OP Delta-T turbine runback setpoint at Turkey Point Units 3 and 4 can be reduced to 2%of nominal loop Delta-T below the trip setpoint to reduce the number of turbine runback alarms.In the event that a turbine runback should occur while the rod control system is in manual, the operator would insert control rods to reduce reactor power to prevent a reactor trip.The safety evaluation concludes that above change does not require a change to the Technical Specifications, does not impact plant safety or safe operation, and does not constitute an unreviewed safety question as defined by lOCFR50.59 (a)(2).Therefore, this activity did not require prior NRC review and approval.Issued: November 22, 1991 212

-PLACING SEQUENCER TEST MODE TO OFF The Sequencers are designed to perform a continuous automatic test and to abort the Auto-Test in response'o a Valid Input.The Sequencer Auto-Test program generates minimum duration pulse signals that, are used in the Programmable Logic Controller (PLC)for the purpose of verifying the PLC program and the circuit continuity.
Certain failures of the PLC output test modules can result in the generation of a false"Valid Signal" that is processed by the sequencer as a field Valid Input.Because this is potentially an undesirable situation, this safety evaluation justifies placing the test mode selector switch to"OFF" and discontinuing use of the Auto-Test.
A Manual Test will be performed on a 30 day interval.Confirmation or modification of the test requirements necessary to fulfill the 30 day surveillance interval will be provided under separate documentation.
The Sequencer Not In Auto Test alarm will also be defeated during this time period in accordance with TSA 4-91-24-40.
These conservative measures will assure that the potential failure mode is eliminated while testing is being performed on a failed test module.Revision 1 of this safety evaluation provides the requirements necessary to meet the 30 day surveillance interval.Safet Eva1uation Summa This safety evaluation concludes that disabling the Sequencer Auto Self-Test feature by placing the test selector switch in OFF does not present an unreviewed safety question or require a change to the Technical Specifications, and does not impact plant operation or safety.Therefore, prior NRC approval was not required pursuant to 10 CFR 50.59.Issued: January 23, 1992 213 SAFETY EVALUATION JPN-PTN-SEFZ-92-001 Revision 0 SAFETY EVALUATION FOR EDDY CURRENT TESTING OF NUCLEAR FUEL AT TURKEY POINT UNIT 4 This safety evaluation reviews the spent fuel rod inspection at Turkey Point Unit 4, using a Spent Fuel Rod Inspection Stand.The potential safety issues associated with performing this inspection are enveloped by the fuel handling analyses previously evaluated in the FSAR.Safet Evaluation Summa This evaluation shows that the eddy current testing of the nuclear fuel at Turkey Point Units 4 does not constitute an unreviewed safety question, does not require a change to the Technical Specifications, and does not impact plant operation or safety.Therefore, prior NRC approval was not required pursuant to 10 CFR 50.59.Issued: January 10, 1992 214 SAFETY EVALUATION JPN-PTN-SECP-92-004 Revision 1 UNIT 3 TWENTIETH YEAR CONTAINMENT TENDON SURVEILLANCE The Technical Specifications, Section 4.6.1.6.1 requires that containment tendon surveillance be performed at one, three and five years (and every five years thereafter) after the initial containment structural integrity test.The containment structure tendon surveillance program is a systematic means of assessing the continued performance of the containment post-tensioning system.The surveillance and construction activities associated with the Unit 3 twentieth year tendon surveillance are restricted such that design basis structural integrity is maintained.
Therefore, surveillance activities may be performed during power operation.

JPN-PTN-SENP-92-009 Revision 0 SUBSTANTIAL SAFETY HAZARDS EVALUATION RELATED TO PRESSURIZER VENTS AT COLD SHUTDOWN Vendor letter FPL-92-529 notifying Florida Power and Light of a potential 10 CFR 21 concern involving the use of pressurizer vents during cold shutdown.This evaluation reviews the issues associated with the Westinghouse letter and the adequacy of level instrumentation associated with reduced inventory operation with respect to INPO SOER 88-3, recommendation 4.The above letter identified a potential issue which relates to limitations of pressurizer venting for decay heat removal at cold shutdown.During a loss of RHR cooling event, there is a potential for water hold-up in the pressurizer if the reactor coolant is allowed to boil.It is possible that the steam velocity in the surge line would be high enough that liquid entrainment prevents water from draining back from the pressurizer into the hot leg.This effect is also called surge line flooding.This Substantial Safety Hazards Evaluation serves two functions.
First, it evaluates the Westinghouse letter with respect to the plant specific conditions at Turkey Point.The Substantial Safety Hazards Evaluation portion concludes that a substantial safety hazard does not exist and is not reportable under 10 CFR 21.Second, the 10 CFR 50.59 safety evaluation portion allows for certain procedure changes that govern reduced inventory operation to be made to enhance the operator's ability to cope with a loss of RHR event.Safet Evaluation Summa The procedure changes recommended in this evaluation provide cautions and notes that provide more information to the operations personnel during loss of RHR events.The procedure changes do not alter the manner or the methodology employed to mitigate loss of RHR events.The safety evaluation concludes that the proposed procedure changes do not require a change to any Technical Specification, did not impact the safety and operation of the plant, and does not constitute an unreviewed safety question.Therefore, prior NRC approval is not necessary.

{TSA)REPLACING CHARGING PUMP 4B RELIEF VALVE RV-4-283B WITH A BLIND FLANGE This Safety Evaluation addresses the temporary replacement of Charging Pump Relief Valve RV-4-283B with blind flanges in accordance with TSA 04-92-47-3 to eliminate a potential leakage path through the valve during troubleshooting.
Testing performed previously has identified leakage of about 5 gpm through one or more of three flow paths associated with the 4B Charging Pump.Eliminating the relief valve as a leakage path allows for checking of the other two potential flow paths.The pressure integrity of the Charging System is maintained by the TSA and an operator will remain in the area while the 4B charging pump{and blind flanges)are exposed to system pressure.Removal of the relief valve is acceptable from an overpressure protection standpoint because the 4B pump will not be operated.During the last In Service Test on the 4A charging pump the flow was inadequate with the 4B pump valved in;however, with the 4B pump isolated, the 4A pump's flow was found to be acceptable.
To be conservative, the 4A charging pump will be declared out of service while the 4B pump is valved in.Considering the 4C charging pump to be the only operable charging pump causes Unit 4 to be in a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> LCO.Sachet Evaluation Summa This safety evaluation concludes that the temporary system alteration does not require any changes to the Plant Technical Specifications, does not affect plant safety or operation, and does not involve an unreviewed safety question pursuant to 10 CFR 50.59.Therefore, prior NRC approval was not required prior to implementation.

JPN-PTN-SEIS-92-013 Revision 0 SAFETY EVALUATION FOR OVERTEMPERATURE AND OVERPOWER DELTA-T TURBINE RUNBACK SETPOINT CHANGE On Friday 11/15/91, Florida Power 6 Light-Turkey Point Unit 3, the Delta-T.parameter used in the Overtemperature/Overpower (OT/OP)Delta-T{DT)setpoint calculation was normalized to 100%power at actual 100%power plant conditions.
During this time the plant began to experience alarms in the OT Delta-T Rod Stop and the Auto Turbine Runback Rod Block on Unit 3 loop B circuit with no significant consequence to plant operation.
Turbine runback requires 2-out-of-3 loops for actuation.
The alarm was caused by fluctuations of the Delta-T signal (Delta-T lead/lag minus the OTDT trip setpoints) which were occasionally reaching the turbine runback setpoint.PC/M 91-191 and 91-192 were issued to change the turbine runback setpoints to l.l F below their respective trip setpoints.
However, several spurious alarms have been received after implementation of the above PC/Ms.This safety evaluation addresses plant operation with the OTDT and OPDT turbine runback setpoints set equal to their respective reactor trip setpoints.
Safet Evaluation Summa The turbine runback on OTDT or OPDT is for plant availability only.As such, the turbine runbacks are considered quality related.Credit is not taken for turbine runback on a OTDT or OPDT signal in any FSAR accident analyses.The results of this safety evaluation show the requested change to the OTDT and OPDT turbine runback setpoints does not have an adverse effect on plant operation or safety, does not constitute an unreviewed safety question, and does not require changes to the Technical Specifications.
Therefore, prior NRC approval was not required pursuant to l0 CFR 50.59.Issued: April 2, 1992 220

JPN-PTN-SEIS-92-014 Revision 0 SAFETY EVALUATION FOR HIGH DELTA-T ALARM SETPOINT CHANGE While preparing scaling drawings for the Eagle-21 System, it was discovered that the High Delta-T alarm setpoint may not be set to the proper value.The High Delta-T alarm is controlled by comparators TC-412A2, TC-422A2 and TC432A2 for Loops A, B and C respectively.
These comparators are calibrated using Plant Procedures 3/4-PMI-041.6I 7, 8.Currently the acceptance criteria given by these procedures require that the setpoint for these comparators be set to 58.8 F.The current setpoint is derived from multiplying 1.05 times the original plant design Delta-T.of 56.1'F,{1.05 X 56.1=58.8).However, during a calibration of the Eagle-21 System at 50%reactor power in Turkey Point Unit 3I it was discovered that the design Delta-T.was being used instead of the required measured Delta-T.during calorimetrics.
Safety evaluation JPN-PTN-SEFJ-91-040 evaluated the effect of using the original plant design Delta-T.on the reactor trip logic.This safety evaluation addresses the current High Delta-T alarm setpoint and provides for revision of the High Delta-T alarm setpoint using the required measured Delta-T..Safet Evaluation Summar The High Delta-T alarm is intended to provide the operator with a warning of an impending Overtemperature or Overpressure Delta-T reactor trip.As such, the High Delta-T alarm is considered Quality Related.Credit is not taken for High Delta-T alarm signal in FSAR accident analysis and the setpoint change introduces no adverse effect on plant operation or safety.The results of this safety evaluation show that operation with the revised High Delta-T alarm setpoint does not constitute an unreviewed safety question and does not require any Technical Specification changes.Therefore, prior NRC approval is not required pursuant to 10 CFR,S0.59.

SECTION 3 RELOAD SAFETY EVALUATIONS 225 RELOAD SAFETY EVALUATIONS PLANT CHANGE MODXFXCATXON 91-018 TURKEY POINT UNIT 4 CYCLE 13 FUEL RELOAD This engineering package (EP), provides the reload core design of the Turkey Point Unit 4 Cycle 13 developed by Florida Power&Light Co.The Cycle 13 energy requirement is 10650 EFPH based on a Cycle 12 length of 9790 EFPH.The primary design change to the core for Cycle 13 is the replacement of 64 irradiated assemblies with 48 fresh Region 15 fuel assemblies and 16 irradiated assemblies re-inserted from previous cycles.The fuel is arranged in a low leakage pattern with no significant differences between the Cycle 13 loading pattern and the Cycle 12 design.Region 15 incorporates Debris Resistant Fuel Assemblies (DRFA)wh'ich use longer fuel rod bottom endcaps and relocated grids.This design was first used at FPL in Turkey Point Unit 3 Cycle 12.In addition, there are several other minor design changes which include: 2)3)an increase in the radius of the fuel rod bottom end plug to facilitate rod loading;addition of a skirt to the bottom nozzle for increased strength;implementation of an anti-snag outer grid strap into the zircaloy grids;and updated WABA assembly which reflect the latest design features for this component.
The safety analysis of this design was performed by Westinghouse and indepen'dently reviewed by Florida Power and Light Co.Supplement 1: Supplement 1 to the EP adds curves of RCS boron concentration required to maintain shutdown margin as a function of temperature and exposure to support operation with a reduced boric acid concentration in the boric acid tanks.These curves provide operational guidance to ensure that shutdown margin is maintained at various RCS temperatures during reactor cooldowns.
This supplement does not affect, amend, or change the original'afety evaluation or any Technical Specifications.
226 Safet Evaluation Summar This safety evaluation concluded that implementation of this EP vill not adversely impact plant safety or operation.
Cycle 13 operation does not pose an unreviewed safety question and can be implemented with no changes to the Turkey Point Technical Specifications.
Therefore, prior NRC approval is not required for implementation.
