The maximum peak pressure resulting from a LOCA event is calculated to be less than the design limit of 12 psig, which includes 0.3 psig for initial positive containment pressure.3/4.6.1.5 AIR TEMPERATURE The limitations on containment average air temperature ensure that 1)the containment air mass is limited to an initial mass sufficiently low to prevent exceeding the design pressure during LOCA conditions and 2)the ambient air temperature does not exceed that temperature allowable for the continuous duty rating specified for equipment and instrumentation located within containment.

The containment pressure transient is sensitive to the initially contained air mass during a LOCA.The contained air mass increases with decreasing temperature.

The lower temperature limit of 60'F will limit the peak pressure to less than the containment design pressure of 12 psig.The upper temperature limit influences the peak accident temperature slightly during a LOCA;however, this limit is based primarily upon equipment protection and anticipated operating conditions.

Both the upper and lower temperature limits are consistent with the parameters used in the accident analyses.3/4.6.1.6 CONTAINMENT VESSEL STRUCTURAL INTEGRITY This limitation ensures that the structural integrity of the containment steel vessel will be maintained comparable to the original design standards for the life of the facility.Structural integrity is required to ensure that (1)the steel liner remains leak tight and (2)the concrete surrounding the steel liner remains capable of providing external missile protection for the steel liner and radiation shielding in the event of a LOCA.A visual inspection in conjunction with Type A leakage tests is sufficient to demonstrate this capability.

COOK NUCLEAR PLANT-UNIT 1 Page B 3/4 6-2

3/4 BASES 3/4.7 PLANT SYSTEMS 3/4.7.1.3 CONDENSATE STORAGE TANK The OPERABILITY of the condensate storage tank with the minimum water volume ensures that sufficient water is available to maintain the RCS at HOT STANDBY conditions for 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> with steam discharge to the atmosphere concurrent with total loss of off-site power.The useable water volume limit reflects the volume of water above the centerline of the discharge pipe.An allowance for water not useable because of tank discharge line location or other physical characteristics is not required.3/4.7.1.4 ACTIVITY The limitations on secondary system specific activity ensure that the resultant off-site radiation dose will be limited to a small fraction of 10 CFR Part 100 limits in the event of a steam line rupture.This dose also includes the effects of a coincident 1.0 gpm primary to secondary tube leak in the steam generator of the affected steam line.These values are consistent with the assumptions used in the accident analyses.3/4.7.1.5 STEAM GENERATOR STOP VALVES The OPERABILITY of the steam generator stop valves ensures that no more than one steam generator will blowdown in the event of a steam line rupture.This restriction is required to 1)minimize the positive reactivity effects of the Reactor Coolant System cooldown associated with the blowdown, and 2)limit the pressure rise within containment in the event the steam line rupture occurs within containment.

The OPERABILITY of the steam generator stop valves within the closure times of the surveillance requirements are consistent with the assumptions

'sed in the accident analyses With one steam generator stop valve inoperable in MODE I, action must be taken to restore OPERABLE status within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.Some repairs to the valves can be made with the unit hot.The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> completion time is reasonable, considering the low probability of an accident occurring during this time period that would require a closure of the steam generator stop valves.If the steam generator stop valve cannot be restored to OPERABLE status within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, the unit must be placed in a MODE in which the LCO does not apply.To achieve this status, the.unit must be placed in MODE 2 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and the MODES 2 and 3 action statement entered.The completion times are reasonable, based on operating experience, to reach MODE 2 and to close the steam generator stop valves in an orderly manner and without challenging unit systems.Since the steam generator stop valves are required to be OPERABLE in MODES 2 and 3, the inoperable valves may either be restored to OPERABLE status or closed.When closed, the valves are already in the position required by the assumptions in the safety analysis.The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> completion time is consistent with the MODE 1 action statement requirement.

For inoperable steam generator stop valves that cannot be restored to OPERABLE status within the specified completion time, but are closed, the inoperable valves must be verified on a periodic basis to be closed.This is necessary to ensure that the assumptions in the safety analysis remain valid.The 7 day completion time is reasonable, based on engineering judgement, in view of steam generator stop valve status indications available in the control room, and other administrative controls, to ensure that these valves are in the closed position.If in MODES 2 or 3 the steam generator stop valves cannot be restored to OPERABLE status or are not closed within the associated completion time, the unit must be placed in a MODE in which the LCO does not apply.To achieve this status, the unit must be placed at least in MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.The allowed completion times are reasonable, based on operating experience, to reach the required unit conditions from MODE 2 conditions in an orderly manner and without challenging unit systems.COOK NUCLEAR PLANT-UNIT 1 Page B 3/4 7-3 AMENDMENT$Q, 48$

',I II BASES 2.0 SAFEIY LIMITS AND LIMITING SAH'Y SYSTEM SKI'INGS 2.1 SAFETY LIMITS 2:1.1 REACTOR CORE The restrictions of this safety limit prevent overheating of the fuel and possible cladding perforation which would result in the release of fission products to the reactor coolant.Overheating of the fuel cladding is prevented by restricting fuel operation to within the nucleate boiling regime where the heat transfer coefficient is large and the, cladding surface temperature is slightly above the coolant saturation temperature.

Operation above the upper boundary of the nucleate boiling regime could result in excessive cladding temperatures because of the onset of departure from nucleate boiling (DNB)and the resultant sharp reduction in heat transfer coefficient.

DNB is not a directly measurable parameter during operation and therefore THERMAL POWER and reactor coolant temperature and pressure have been related to DNB through the WRB-2 correlation and W-3 correlation for conditions outside the range of WRB-2.The DNB correlations have been developed to predict the DNB flux and the location of DNB for axially uniform and nonuniform heat flux distributions.

The local DNB heat flux ratio (DNBR)is defined as the ratio of the heat flux that would cause DNB at a particular core location to the local heat flux, and is indicative of the margin to DNB.The DNB design basis is as follows: there must be at least a 95 percent probability that the minimum DNBR of the limiting tod during Condition I and II events is greater than or equal to the DNBR limit of the DNB correlation being used (the WRB-2 correlation for Vantage-5 fuel, and the W-3 conelation for conditions which fall outside the range of applicability of the WRB-2).The correlation DNBR limits are established based on the entire applicable experimental data set such that there is a 95 percent probability with 95 percent confidence that DNB will not occur when the minimum DNBR is at the DNBR limit (1.17 for WRB-2 and 1.3 for the W-3).In meeting the DNB design basis, uncertainties in plant operating parameters, nuclear and thermal parameters, and fuel fabrication parameters are statistically combined with the DNBR correlation statistics such that there is at least a 95 percent probability with a 95 percent confidence level that the minimum DNBR for the limiting rod is greater than or equal to a calculated design limit DNBR.The uncertainties in the above plant parameters are used to determine the plant DNBR uncertainty.

This DNBR uncertainty, combined with the DNBR correlation statistics, establishes a design DNBR value which must be met in plant safety analyses using values of input parameters without uncertainties.

For Cook Nuclear Plant Unit 2, the design DNBR values are 1.23 and 1.22 for Vantage-5 fuel typical and thimble cells, respectively.

In addition, margin has been maintained by performing safety analyses to a safety analysis limit DNBR.The margin between the design and safety analysis limit DNBR is used to offset known DNBR penalties (i.e., transition core penalties, rod bow, etc,)and provide DNBR margin for operating and design flexibility.

The curves of Figure 2.1-1 show the loci of points of THERMAL POWER, Reactor Coolant System pressure, and average temperature below which the calculated DNBR is no less than the design DNBR limit value or the average enthalpy at the vessel exit is less than the enthalpy of saturated liquid.COOK NUCLEAR PLANT-UNIT 2 Page B 2-1 AMENDMENT 84, 434, BASES 2.0 SAFEIY LIMITS AND LIIUKI1NG SAIK'IY SYSTEM SETHNGS 2.2.1 REACTOR TRIP SYSTEM INSTRUMENTATION SETPOINTS (Continued)

Ove wer Delta T The Overpower Delta T reactor trip provides assurance of fuel integrity, e.g., no melting, under all possible overpower conditions, limits the required range for Overtemperature Delta T protection, and provides a backup to the High Neutron Flux trip.The setpoint includes corrections for changes in density and heat capacity of water with temperature, and dynamic compensation for piping delays from the core to the loop temperature detectors.

The overpower delta T reactor trip provides protection or back-up protection for at-power steam line break events.Credit was taken for operation of this trip in the steam line break mass/energy releases outside containment analysis.In addition, its functional capability at the specified trip setting is required by this specification to enhance the overall reliability of the Reactor Protection System.Pressurizer Pressure The Pressurizer High and Low Pressure trips are provided to limit the pressure range in which reactor operation is permitted.

The High Pressure trip is backed up by the pressurizer code safety valves for RCS overpressure protection, and is therefore set lower than the set pressure for these valves (2485 psig).The High Pressure trip provides protection for a Loss of External Load event.The Low Pressure trip provides protection by tripping the reactor in the event of a loss of reactor coolant pressure.Pressurizer Water Level The Pressurizer High Water Level trip ensures protection against Reactor Coolant System overpressurization by limiting the water level to a volume sufficient to retain a steam bubble and prevent water relief through the pressurizer safety valves.The pressurizer high water level trip precludes water relief for the uncontrolled control rod assembly bank withdrawal at-power event.COOK NUCLEAR PLANT-UNIT 2 Page B 2-5 AMENDMENT 82, 434, 442, 3/4 BASES 3/4.2 POKER DIS'GUBUTION LIMITS 3/4.2.2 and 3/4.2.3 HEAT FLUX HOT CHANNEL FACTOR AND NUCLEAR ENTHALPY RISE HOT CHANNEL FACTOR Continued When RCS flow rate and PAH are measured, no additional allowances are necessary prior to comparison with the limits of Specification 3.2.3.Measurement errors of 2.1%for RCS flow total flow rate and 4%for F>H have been allowed for in determination of the design DNBR value and in the determination of the LOCA/ECCS limit.Margin between the safety analysis DNBRs and the design limit DNBRs is maintained.(Safety analyses DNBRs: 1.69 and 1.61 for the Vantage 5 typical and thimble cells, respectively.

Design limit DNBRs: 1.23 and 1.22 for the Vantage 5 typical and thimble cells, respectively.)

A fraction of this margin is utilized to accommodate applicable transition core penalties and the appropriate fuel rod bow DNBR penalty for the Vantage 5 fuel (equal to 1.3%per%CAP-8691, Rev.1).The remainder of the margin between design and safety analysis DNBR limits can be used for plant design flexibility.

3/4 BASES 3/4.2 POWER DISTRIBUTION LIMITS 3/4.2.4 UADRANT POWER TILT RATIO The quadrant power tilt ratio limit assures that the radial power distribution satisfies the design values used in the power capability analysis.Radial power distribution measurements are made during startup testing and periodically during power operation.

The limit of 1.02 at which corrective action is required provides DNB and linear heat generation rate protection with x-y plane power tilts.The two hour time allowance for operation with a tilt condition greater than 1.02 but less than 1.09 is provided to allow identification and correction of a dropped or misaligned rod.In the event such action does not correct the tilt, the margin for uncertainty on F~is reinstated by reducing the power by 3 percent from RATED THERMAL POWER for each percent of tilt in excess of 1.0.3/4.2.5 DNB PARAMETERS The limits on the DNB-related parameters ensure that each of the parameters are maintained within the normal steady-state envelope of operation assumed in the transient and accident analyses.The Tav<less than or equal to 583.3'F and pressurizer pressure greater than or equal to 2200 psig (for nominal pressurizer operating pressure of 2235 psig)or greater than or equal to 2050 psig (for nominal pressurizer operating pressure of 2085 psig)are consistent with the UFSAR assumptions and have been analytically demonstrated adequate to maintain the core at or above the design DNBR thoughout each analyzed transient with allowance for measurement uncertainty.

Pressurizer pressure is limited to either of two nominal operating pressures of 2235 psig or 2085 psig, with the corresponding indicated limits set forth in the specifications.

The limits are consistent with the UFSAR assumptions and have been analytically demonstrated to be adequate to maintain the core at or above the applicable design limit DNBR value for the current fuel type throughout each analyzed transient.

The 12-hour surveillance of the RCS flow measurement is adequate to detect flow degradation.

The CHANNEL CALIBRATION performed after refueling ensures the accuracy of the shiftly flow measurement.

The total flow is measured after each refueling based on a secondary side calorimetric and measurements of primary loop temperatures.

COOK NUCLEAR PLANT-UNIT 2 Page B 3/4 2-5 AMENDMENT S2, 434, 0 f 0 3/4 BASES 3/4.4 REACTOR COOLANT SYSTEM 3/4.4.9 PRESSURE/TEMPERATURE LIMITS All components in the Reactor Coolant System are designed to withstand the effects of cyclic loads due to system temperature and pressure changes.These cyclic loads are introduced by normal load transients, reactor trips, and startup and shutdown operations.

The various categories of load cycles used for design purposes are provided in Section 4.1.4 of the FSAR.During startup and shutdown, the rates of temperature and pressure changes are limited so that the maximum specified heatup and cooldown rates are consistent with the design assumptions and satisfy the stress limits for cyclic operation.

An ID or OD one-quarter thickness surface flaw is postulated at the location in the vessel which is found to be the limiting case.There are several factors which influence the postulated location.The thermal induced bending stress during heatup is compressive on the inner surface while tensile on the outer surface of the vessel wall.During cooldown the bending stress profile is reversed.In addition, the material toughness is dependent upon irradiation and temperature and therefore, the fluence profile through the reactor vessel wall, the rate of heatup and also the rate of cooldown influence the postulated flaw location.The heatup limit curve, Figure 3.4.2, is a composite curve which was prepared by determining the most conservative case, with either the inside or outside wall controlling, for any heatup rate up to 60'F per hour.The cooldown limit curves of Figure 3.4-3 are composite curves which were prepared based upon the same type analysis with the exception that the controlling location is always the inside wall where the cooldown thermal gradients tend to produce tensile stresses while producing compressive stresses at the outside wall.The heatup and cooldown curves were prepared based on the most limiting value of the predicted adjusted reference temperature at the end of 14.5 EFPY.The reactor vessel materials have been tested to determine their initial RTND T.The results of these tests are shown in Table B 3/4.4-1.Reactor operation and resultant fast neutron (E)1 MeV)irradiation will cause an increase in the RTNDT.Therefore, an adjusted reference temperature must be predicted in accordance with Regulatory Guide 1.99, Revision 2.This prediction is based on the fluence and a chemistry factor determined from one of two Positions presented in the Regulatory Guide.Position (1)determines the chemistry factor from the copper and nickel content of the material.Position (2)utilizes surveillance data sets which relate the shift in reference temperature of surveillance specimens to the fluence.The selection of Position (1)or (2)is made based on the availability of credible surveillance data, and the results achieved in applying the two Positions.

3/4 BASES 3/4.4 REACTOR COOLANT SYSTEM 3/4.4 9 PRESSURE/TEMPERATURE LIMITS Continued The actual shift in the reference temperature of surveillance specimens and neutron fluence is established periodically by removing and evaluating reactor vessel material irradiation surveillance specimens and dosimetry installed near the inside wall of the reactor vessel in the core area.The heatup and cooldown limit curves of Figures 3.4-2 and 3.4-3 include predicted adjustments for this shift in RT>>r at the end of 14.5 EFPY, as well as adjustments for possible errors in the pressure and temperature sensing instruments.

The 14.5 EFPY heatup and cooldown curves were developed based on the following:

1.The intermediate shellplate, C5556-2, is the limiting material as determined by position I of Regulatory Guide 1.99, Revision 2, with a Cu and Ni content of 0.15%and 0.57%, respectively.

2.The fluence values contained in Table 6-14 of Westinghouse WCAP-13515 report,"Analysis of Capsule U From the Indiana Michigan Power Company D.C.Cook Unit 2 Reactor Vessel Radiation Surveillance Program", dated February 1993.The RT>>r shift of the reactor vessel material has been established by removing and evaluating the reactor material surveillance capsules in accordance with the removal schedule in Table 4.4-5.Per this schedule, Capsule U is the last capsule to be removed until Capsule S is to be removed after 32 EFPY (EOL).Capsules V, W, and Z will remain in the reactor vessel and will be removed to address industry reactor vessel embrittlement concerns, if required.The pressure-temperature limit lines shown on Figure 3.4-2 for reactor criticality and for inservice leak and hydrostatic testing have been provided to assure compliance with the minimum temperature requirements of Appendix G to 10 CFR 50.The number of reactor vessel irradiation surveillance specimens and the frequencies for removing and testing these specimens are provided in Table 4.4-5 to assure compliance with the requirements of Appendix H to 10 CFR Part 50.The limitations imposed on pressurizer heatup and cooldown and spray water temperature differential are provided to assure tliat the pressurizer is operated within the design criteria assumed for the fatigue analysis performed in accordance with the ASME Code requirements.

The OPERABILITY of two PORVs, or of one PORV and the RHR safety valve ensures that the RCS will be protected from pressure transients which could exceed the limits of Appendix G to 10 CFR Part 50 when one or more of the RCS cold legs are less than or equal to 152'F.Either PORV or RHR safety valve has adequate relieving capability to protect the RCS from overpressurization when the transient is limited to either (1)the start of an idle RCP with the secondary water temperature of the stem generator less than or equal to 50'F above the RCS cold leg temperatures of (2)the start of a charging pump and its injection into a water solid RCS.Therefore, any one of the three blocked open PORVs constitutes an acceptable RCS vent to preclude APPLICABILITY of Specification 3.4.9.3.3/4.4.10 STRU TURAL INTEGRITYThe inspection and testing programs for ASME Code Class 1, 2 and 3 components ensure that the structural integrity of these components will be maintained at an acceptable level throughout the life of the plant.To the extent applicable, the inspection program for these components is in compliance with Section XI of the ASME Boiler and Pressure Vessel Code.COOK NUCLEAR PLANT-UNIT 2 Page B 3/4 4-10 AMENDMENT BQ, 423, 4A, 474 iJ, ,L 3/4 BASES 3/4,5 EMERGENCY CORE COOLING SYSTEMS-3/4.5.1 ACCUMULATORS Continued allowed completion times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.If more than one accumulator is inoperable, the plant is in a condition outside the accident analyses;therefore, LCO 3.0.3 must be entered immediately.

3/4.5.2 311d 3/4.5.3 ECCS SUBSYSTEMS The OPERABILITY of two independent ECCS subsystems ensures that sufficient emergency core cooling capability will be available in the event of a LOCA assuming the loss of one subsystem through any single failure consideration.

Either subsystem operating in conjunction with the accumulators is capable of supplying sufficient core cooling to limit the peak cladding temperatures within acceptable limits for all postulated break sizes ranging from the double ended break of the largest RCS cold leg pipe downward.In addition, each ECCS subsystem provides long term core cooling capability in the recirculation mode during the accident recovery period.COOK NUCLEAR PLANT-UNIT 2 Page B 3/4 5-la AMENDMENT BQ, 447, 440, 1 II 3/4 BASES 3/4.6 CONTAINMENT SYSTEMS 3/4.6.1.4 INTERNAL PRESSURE The limitations on containment internal pressure ensure that 1)the containment structure is prevented from exceeding its design negative pressure differential with respect to the outside atmosphere of 8 psig and 2)the containment peak pressure does not exceed the design pressure of 12 psig during LOCA conditions.

The maximum peak pressure resulting from a LOCA event is calculated to be less than the design limit of 12 psig, which includes 0.3 psig for initial positive containment pressure.3/4.6.1.5 AIR TEMPERATURE The limitations on containment average air temperature ensure that I)the containment air mass is limited to an initial mass sufficiently low to prevent exceeding the design pressure during LOCA conditions and 2)the ambient air temperature does not exceed that temperature allowable for the continuous duty rating specified for equipment and instrumentation located within containment.

The containment pressure transient is sensitive to the initially contained air mass during a LOCA.The contained air mass increases with decreasing temperature.

The lower temperature limit of 60'F will limit the peak pressure to less than the containment design pressure of 12 psig.The upper temperature limit influences the peak accident temperature slightly during a LOCA;however, this limit is based primarily upon equipment protection and anticipated operating conditions.

Both the upper and lower temperature limits are consistent with the parameters used in the accident analyses.3/4.6.1.6 CONTAINMENT VESSEL STRUCTURAL INTEGRITY This limitation ensures that the structural integrity of the containment will be maintained comparable to the original design standards for the life of the facility.Structural integrity is required to ensure that (1)the steel liner remains leak tight and (2)the concrete surrounding the steel liner remains capable of providing external missile protection for the steel liner and radiation shielding in the event of a LOCA.A visual inspection in conjunction with Type A leakage tests is sufficient to demonstrate this capability.

For inoperable steam generator stop valves that cannot be restored to OPERABLE status within the specified completion time, but are closed, the inoperable valves must be verified on a periodic basis to be closed.This is necessary to ensure that the assumptions in the safety analysis remain valid.The 7 day completion time is reasonable, based on engineering Judgement, in view of steam generator stop valve status indications available in the control zoom,'and other adlai.stzative controls, to ensure that these valves are in the closed position.Xf in NODES 2 or 3 the steam generator stop valves cannot be restored to OPERABLE status or aze not closed within the associated completion time, the unit must be placed in a MODE in which the LCO does not apply.To achieve this status, the unit-must be placed at least in MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in NODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.The allowed completion times aze reasonable, based on operating experience, to reach the required'nit conditions from MODE 2 conditions in an orderly manner and without challenging unit systems.COOK NUCLEAR PLANT-UNXT 1 B 3/4 7-3a AMENDMENT NO.185,

J ACTOR COOLANT SYSTEM BASES 3 4.4.9 PRESSURE TEMPERATURE LIMITS I All components in the Reactor Co olant System are designed to withstand the effects of cyclic loads due to system temperature and pressure changes.These cyclic loads are introduced by normal load transients, reactor trips, and startup and shutdown operations.

The various categories of load cycles used for design purposes are provided in Section 4.1.4 of the FSAR.During startup and shutdown, the rates of temperature and pressure changes are limited so that the maximum specified heatup and cooldown rates are consistent with the design assumptions and satisfy the stress limits for cyclic operation.

An ZD or OD one~arter thickness surface flaw is postulated at the location in the vessel which is found to be the limiting case.There are several factors which influence the postulated location.The thermal induced bending stress during heatup is compressive on the inner surface while tensile on the outer surface of the vessel wall.During cooldown, the bending stress profile is reversed.Zn addition, the material toughness is dependent upon irradiation and temperature and therefore, the fluence profile through the reactor vessel wall, the rate of heatup and also the rate of cooldown influence the postulated flaw location.The heatup limit curve, Figure 3.4.2, is a composite curve which=was prepared by determining the most conservative case, with either the inside or outside wall controlling, for any heatup rate up to 60'F per hour.The cooldown limit curves of Figure 3.4-3 are composite curves which were prepared based upon the same type analysis with the exception that the controlling location is always the inside wall where the cooldown thermal gradients tend to produce tensile stresses while producing compressive stresses at the outside wall.The heatup and cooldown curves were prepared based on the most imiting value of the predicted adjusted reference temperature at the end of EFPY.t9.8'he reactor vessel materials have been tested to determine their initial RTmn.'he results of these tests are shown in Table B 3/4.4-1.Reactor operation and resultant fast neutron (E>1 MeV)irradiation will cause an increase in the RT~.Therefore, an adjusted reference temperature must be predicted in accordance with Regulatory Guide 1.99, Revision 2.This prediction is based on the fluence and a chemistry-factor determined from one of two Positions presented in the Regulatory Guide.position (1)determines the chemistry factor from the copper and nickel content of the material.Position (2)utilizes surveillance data sets which relate the shift in reference temperature of surveillance specimens to the fluence.The selection of Position (1)or (2)is made based on the availability of credible surveillance data, and the results achieved in applying the two Positions.

COOR NUCLEAR PLANT-UNIT 2 0 3/4 4-6 AMENDMENT NO.69 i,~, 17),

REACTOR COOLANT SYSTEM BASES The actual shift in the reference temperature of surveillance specimens and neutron fluence is established periodically by removing and evaluating reactor vessel material irradiation surveillance specimens and dosimetry installed near the inside wall of the reactor vessel in the core area.The heatup and cooldown limit curves of Figures 3.4-d 3.4-3 predicted adjustments for this shift in RT~at the end of FPY, as adjustments f'r possible errors in the pressure and emperature instruments.

The EFPY heatup and cooldown curves were developed based f ollowing: include well as sensing on the 1.The intermediate shellplate, C5556-2, is the limiting material as determined by position 1 of Regulatory Guide 1.99, Revision 2, with a Cu and Ni content of 0.15%and 0.57%, respectively.

2~The fluence values contained in Table 6-14 of Westinghouse WCAP-13515 report,"Analysis of Capsule U From the Indiana Michi,gan Po~er Company D.C.Cook Unit 2 Reactor Vessel Radiation Surveillance Program", dated February 1993.The RT~shift of the reactor vessel material has been established by removing and evaluating the reactor material surveillance capsules in accordance with the removal schedule in Table 4.4-5.Per this schedule, Capsule U is the last capsule to be removed until Capsule S is to be removed after 32 EFPY (EOL).Capsules V, W, and 2 will remain in the reactor vessel and will be removed to address industry reactor vessel embrittlement concerns, if required.The pressure-temperature limit lines shown on Figure 3.4-2 for reactor criticality and for inservice leak and hydrostatic testing have been provided to assure compliance with the minimum temperature requirements of Appendix G to 10 CFR 50.The number of reactor vessel irradiation surveillance specimens and the frequencies for removing and testing these specimens are provided in Table 4.4-5 to assure compliance with the requirements of Appendix H to 10 CFR Part 50.The limitations imposed on pressurizer heatup and cooldown and spray water temperature differential are provided to assure that the pressurizer is operated within the design criteria assumed for the fatigue analysis performed accordance with the ASME Code requirements.

The OPERABILITY of two PORVs, or of one PORV and the RHR safety valve ensures that the Rcs will be protected from pressure transients which could exceed the limits of Appendix G to 10 CFR Part 50 when one or more of the RCS cold legs are less than or equal to 1524F.Either PORV or RHR safety valve has adequate relieving capability to protect the RCS from overpressurization when the transient is limited to either (1)the start of an idle RCP with the secondary water temperature of the stem generator less than or equal to 50'F above the RCS cold leg temperatures of (2)the start of a charging pump and injection into a water solid RCS~Therefore, any one of the three blocked open PORVs constitutes an acceptable RCS vent to preclude APPLICABILITY of Specification 3.4.9.3.3 4.4.10 STRUCTURAL INTEGRITY The inspection and testing programs for ASME Code Class 1, 2 and 3 components ensure that the structural integrity of these components will be maintained at an acceptable level throughout the life of the plant.To the extent applicable, the inspection program for these components is in compliance with Section XZ of the ASME Boiler and Pressure Vessel Code.COOK NUCLEAR PLANT-UNIT 2 B 3/4 4-10 AMENDMENT NO~89,~i 15k i 171

The containment pressure transient is sensitive to the initially contained air mass during a LOCA.The contained.air mass increases with decreasing temperature.

The lower temperature limit of 60'F will limit k P PP~t I tk t d tg pressure of 12 psig.The'upper temperature limit influences the peak accident temperature slightly during a LOCA;however, this limit is based primarily upon equipment protection and anticipated operating conditions.

Both the upper and lower temperature limits are consistent with the para-meters used in the accident analyses.3/4.6.1.6 CONTAIHMEHT STRUCTURAL INTEGRITY This limitation ensures that the structural integrity of the con-tainment w'ill be maintained comparable to the original design standards for the life of the facility.Structural integrity is required to ensure that (1)the steel liner remains leak tight and (2)the concrete surround-ing the steel liner remains capable of providing external missile protec-tion for the steel liner and radiation shielding in the event of a LOCA.A visual inspection in conjunction with Type A leakage tests is sufficient to demonstrate this capability.

(i Attachment 4 to AEP:NRC:1223 Page 2 Page 2-2 Section 1.3 Figure 2.1-1 Group.Uprate Margin Description Increase rated thermal power to 3588 MNt.Revise Reactor Core Safety Limits Remarks The support for this proposed change consists of analyses that have been performed over a period of years.Including the new analyses, which are described in Attachment 6, NCAP 14489, and the evaluations described in Attachment 7, Balance of Plant Evaluations and Miscellaneous Safety Evaluations, all the necessary analyses and evaluations have been completed to support an uprate of Unit 2 to a core power of 3588 MNt.The new analyses and summaries of earlier analyses and evaluations performed by Westinghouse Electric Corporation for the nuclear steam supply system (NSSS)are described in NCAP 14489.The impact of recent model changes on.the new analyses is discussed in Attachment 1 under Group 1 changes as well as in Attachment 6.Attachment 7 describes balance of plant evaluations and miscellaneous safety evaluations.

Since the analyses which support the uprated power have been performed over a period of years, Attachment 5 is provided to describe the history of earlier analyses and to identify the submittal of earlier work and the associated SER's.The review status of the analyses supporting the uprated core power is discussed in Attachment 1 under Group 1 changes and in Attachment 5.The Safety Limit Figure currently in the Unit 2 Technical Specifications was designed for a mixed core of Westinghouse and Advanced Nuclear Fuel.The Unit 2 core now consists totally of Westinghouse Vantage 5 fuel.The new thermal design is discussed in Section 3.3.2.1 of Attachment 6 WCAP 14489'he proposed Safety Limit Figure is consistent with a rated thermal power of 3588 MWt and an all Vantage 5 core.

Attachment 4 to AEP:NRC:1223 Page 3 Page 2-5 Section Table 2.2-1 Footnote Group Admin Description Redefine design flow in footnote of Table 2.2-1 to be 1/4 MMF.Remarks Minimum Measured Flow (MMF)is Reactor Coolant System Total Flow Rate of T.S.3.2.5.MMF is used directly in the DNB analyses as discussed in Section 3.3.2.1 of Attachment 6, WCAP 14489.MMF is 1'35 times thermal design flow (TDF).Therefore, the MMF employed in the DNB analysis is 1.035 times TDF.TDF is specified in Section 3.3.3.1 of WCAP 14489.TDF is generally used in no-DNB analyses.See, for example, WCAP 14489 tables 3.1-7 and 3.1-13.A lower (loop)TDF is indicated in Table 3.5-1 because the containment analysis bounds both units and Unit 1 is analyzed for a St flow asymmetry.

Design flow in current technical specification Table 2.2-1 is loop MMF or total MMF/4.2-7 2-7 2-7 Table 2.2-1 Margin Table 2.2-1 Margin Table 2.2-1 Margin The upper limit on T'ncreased to 581.34F to reflect analyses.Both analyzed, nominal RCS pressures, 2235 psig and 2085 psig, are indicated.

Tau 1 reduced from 28 secs to 22 secs.New OTDT and OPDT setpoints have been calculated to support operation at a rated thermal power of 3588 MWt with all Westinghouse Vantage 5 cores which are currently being used in Unit 2.K1 was increased from its current value of 1.09 to 1.17 thereby signi,ficantly increasing load rejection margin.The value 1.17 was selected to allocate some margin to instrumentation, increased allowance for core burnup effects such as changes in hot leg streaming, and an increase in the positive~I break point for the f(~I)penalty.Increased load rejection margin was also obtained by reducing tau 1 from 28 seconds to 22 seconds.The analysis value of K4 was also evaluated to obtain increased margin for burnup effects.The OTDT and OPDT trips are discussed in Section 3.3.2.1 of WCAP 14489.Details, including T', T', and time constants of the analyzed setpoint, are in Table 3.3-4 of WCAP 14489.Due to the analysis performed for transition cores of both Westinghouse and Advanced Nuclear Fuel, low pressure operation was not permitted for operation with mixed cores of Westinghouse and Advanced Nuclear Fuel.The basis for this limitation is discussed in Section"Group 4" of Attachment 1.Unit 2 is currently operated with cores of all Westinghouse Vantage 5 fuel.Therefore, low pressure operation is acceptable.

Therefore, the OPDT setpoint was analyzed with a low upper limit on Tto convert unused margin to operating margin.The OPDT trip is discussed in Section 3.3.2.1 of WCAP 14489.Details, including T, of the analyzed setpoint are in Table 3.3-4 of WCAP 14489.The values indicated in the markups of'Attachment 3 and in the proposed technical specifications of Attachment 2 were calculated by our organization using the Westinghouse"stepit" methodology described in WCAP-12741.

This is the same methodology used for the calculation of all existing Reactor Trip and Engineered Safety Feature Actuation Setpoints.

This methodology is consistant with the requirements of ISA Standard S67.04.

Attachment 4 to AEP:NRC:1223 Page 5 Page 3/4 2-15 Section Section 3.2.5 Group Transit ion Description Increase DNB temperature limit from 578.74F to 583.30F.Remarks Due to the analysis performed for transition cores consisting of both Westinghouse fuel and Advanced Nuclear Fuel, the maximum nominal Tavg was limited to 576 F for operation with mixed cores of Westinghouse and Advanced Nuclear Fuel.Unit 2 is currently operated with cores of all Westinghouse Vantage 5 fuel.Therefore, the full analyzed temperature window analyzed for an all Vantage 5 core is acceptable.

The DNB temperature limit is obtained by adding the controller allowance to the high nominal Tavg used in the analysis and then subtracting the readability allowance.

The high nominal Tavg for a full Vantage 5 core is 581.34F and the controller allowance is 4.1oF.These values are found in Table 3.3-1 and Section 3.3.3.1 of WCAP 14489, respectively.

The readability allowance, calculated by AEPSC, is 2.1 F.The resulting DNB temperature limit is 583.3OF.The high nominal Tavg for a full Vantage 5 core is identified in the Vantage 5 Reload Transition Safety Report for Cook Nuclear Plant Unit 2 (RTSR), reference 11 of Attachment 5.RTSR was submitted via reference 13 of Attachment 13 of Attachment 5.Operation of Unit 2 with Westinghouse fuel was approved in reference 17 of Attachment

Remove reference to low temperature limit in order to return the specification to a purely DNB specification.

Reduce safety injection actuation setpoint on low pressurizer pressure to 1815 psig.Remarks Due to the analysis performed for transition cores consisting of both Westinghouse fuel and Advanced Nuclear Fuel, low pressure operation was not permitted for operation with mixed cores of Westinghouse and Advanced Nuclear Fuel.The basis for this limitation is discussed in Section"Group 4" of Attachment 1.Unit 2 is currently operated with cores of all Westinghouse Vantage 5 fuel.Therefore, low pressure operation is acceptable.

The DNB pressure limit is obtained by subtracting the total pressure allowance used in the analysis from the nominal operating pressure used in the analysis and then adding the readability allowance.

The nominal pressures and the total allowance are found in Section 3.3.1 and 3.3.3.1 of WCAP 14489, respectively.

The readability allowance, calculated by AEPSC, is 18.9 psi.The pressure limit currently in the T/Ss for high pressure operation is conservatively higher than the calculated value of 2191 psig.The proposed limit of 2050 psig for low pressure operation is an addition.Zt is conservatively higher than the calculated value of 2041 psig.The proposed value for the low pressure limit is the same as the unit 1 limit.The proposed change converts the DNB speci.fication back to a purely DNB specification.

This proposal is discussed further in Attachment 1.Additional margin to trip for safety injection on low pressurizer pressure was needed as discussed in the description of changes for Group 4 of Attachment 1.The required evaluations to lower the safety analysis value for the setpoint have been performed as discussed in Sections 3.3.4.5 and 3.3.4.6 of WCAP 14489.The nominal Technical Specification setpoint proposed is the same as the corresponding setpoint for Unit 1.Th'e instrument allowances calculated by our organization support this nominal setpoint.

Et is consistent with value for unit 1 and is proposed in order to make the Technical Specifications of the two units more similar.At the time of the transition from Advanced Nuclear Fuel to Westinghouse fuel, the reanalysis of mass and energy release (M&E)outside containment for rerating and reduced temperature/reduced pressure operation was not complete.The evaluation of the then applicable analysis assumed an NSSS power of 3425 MWt and a nominal setpoint for low steam line pressure no less than 520 psig.The AEPSC analysis of the impact of the steam line mass and energy release (SM&E)outside containment on the operabilit of equipment in the main steam enclosures, at 3588 MWt core power, was described and submitted in reference 24 of Attachment 5.Reference 24 was our proposal to operate both units with 0 ppm boron concentration in the boron injection tank (BZT).The SHEE was analyzed consistently with the proposed safety injection setpoint on low steam line pressure.The mass and energy release portion of this analysis is discussed in Section 3.3.4.7 of WCAP 14489.The core response steamline and feedwater line breaks submitted with the RTSR support the proposed setpoint.The references for the RTSR, its submittal, and approval are 11, 13, and 17 of Attachment 5.Evaluations of these analyses are discussed in Sections 3.3.4.6 and 3.3.4.7 of WCAP 14489.The revised SM&E release analysis to containment also supports the proposed setpoint.This analysis is discussed in WCAP 14285, reference 29 of Attachment 5.WCAP 14285 was submitted via reference 30 of Attachment 5.Zt is not yet approved.This analysis is summarized, in Section 3.5.4 of WCAP 14489.

It is consistent with value for unit 1 and is proposed in order to make the Technical Specifications of the two units more similar.See remark on reduction of safety injection actuation on lo steam line pressure on page 3/4 3-23.See remark on the change of allowable value for safety injection actuation setpoint on low steam line pressure on page 3/4 3-23.The Non-LOCA accidents were reanalyzed or reevaluated based on a pressurizer valve setpoint tolerance of 3%.This is noted in section 1.1 and 3.3.2.2 of WCAP 14489.The analyses affected are discussed in Sections 3.3.4.3, 3.3.4.4, 3.3.4.6, 3.3.5.1, and 3.3.5.2 of WCAP 14489.This requirement is consistent with a similar requirement which was approved for the main steam safety valves.It is being submitted for both units because it was inadvertently omitted in our submittal AEP:NRC:1207, dated May 26, 1995, which included the analytical justification for an increase in pressurizer safety valve setpoint tolerance for Unit 1.See remark on setpoint tolerance magnitude on page 3/4 4-4.See remark on as left setpoint tolerance on page 3/4 4-4.

The applicability of the current heatup and cooldown curves is discussed in Section 3.11.2.1 of Attachment 6, WCAP 14489.See the xemark on the applicability of the heatup and cooldown curves on page 3/4 4-25 When the SBLOCA analysis performed to support the main stea safety valve tolerance relaxation to 3%was carried out, it was found that a power reduction was required to obtain satisfactory results with the high head safety injection (HHSZ)cross ties closed.Since then, improvements have been made to the Westinghouse NOTRUMP SBLOCA model.As indicated in the cover letter to this submittal, the SBLO analysis performed for this submittal was performed using the new model.The results of this analysis show that an acceptable PCT results with the HHSZ cross tie valves closed at a core power of 3588 MWt.The SBLOCA analyses are described in Section 3.1.2.4 of WCAP 14489.3/4 7-2 Table 3.7-1 Uprate Lower the maximum Allowable Power Range Setpoint.These setpoints are calculated in accordance with the prescription in Westinghouse Nuclear Safety Advisory Letter 94-001.Zn this prescription, nominal NSSS power appears in the denominator of the equation for the setpoint.Therefore, the proposed setpoints were lowered accordingly.

ATTACHMENT 5 TO AEP:NRC:1223 DISCUSSION OF PREVIOUS RELATED SUBMISSIONS

Attachment 5 to AEP:NRC:1223 Page 1 Introduction The analyses that support the proposed uprating of Donald C.Cook Nuclear Plant unit 2 have been performed over a period of years in several contexts.The analysis of the nuclear steam supply system (NSSS)for an NSSS power of 3600 MWt was performed in conjunction with analyses to operate unit 1 at reduced temperature and pressure (the"Rerating Program").Most of the core response analyses were performed at an uprated core thermal power of 3588 MWt as a part of the transition from Advanced Nuclear Fuel to Westinghouse Vantage 5 fuel.The recently submitted analyses, AEP:NRC:1223, to support an increase in the permitted level of steam generator tube plugging (SGTP)for unit 1 includes a steam mass and energy release (SM&E)analysis to the containment which bounds both units at 3600 MWt.For this submittal, previous NSSS analyses and core response analyses have been reviewed, new analyses have been performed where necessary, and the balance of plant (BOP)evaluated, as described within this submittal, to support the proposal to increase the core rated thermal power to 3588 MWt.Attachment 6 to this submittal is WCAP 14489.Xt describes the analyses, evaluations, and reviews performed by Westinghouse Electric Corporation and summarizes earlier work performed by Westinghouse Electric Corporation to support an increased core rated thermal power for unit 2.WCAP 14489 also describes analyses and evaluations performed simultaneously to support certain increases in operating margin such as increased setpoint tolerance for the pressurizer safety valves.Attachment 7 discusses balance of plant evaluations that have been performed by AEPSC to assess the impact of increased core power.Section 2.0 of WCAP 14489 discusses the previous work performed by Westinghouse Electric Corporation to support the uprated core power for unit 2.The evaluations described in WCAP 14489 are based on these earlier analyses.The earlier analyses are described in Rerating Program WCAP's 11902 and 11902 Supplement 1, references 3 and 10, and in the Vantage 5 Reload Transition Safety Report for Donald C.Cook Nuclear Plant Unit 2, Revision 1, March 1990 (RTSR), reference 11.The SGTP SMEE analysis is described in WCAP 14285, reference 29.WCAP 11902 and its supplement are referred to as the"Rerating Program" in WCAP 14489.The reload transition safety report is referred to as"RTSR" in WCAP 14489.The increase in the permitted level of steam generator tube plugging program is referred to as"SGTP Program" in WCAP 14489.The rerating Program, RTSR, SGTP Program, WCAP 14489 (the unit 2 Uprating Program), and the BOP evaluations provide the support for this submittal.

Pu ose of Attachment 5 The purposes of.this attachment are to: 2.indicate those aspects of earlier analyses which have been submitted for NRC review and approved, indicate those aspects of earlier analyses which have been submitted for NRC review but are not yet approved (This category is comprised of the SGTP Program.),

Attachment 5 to AEP:NRC:1223 Page 2 3.4~briefly describe the earlier analyses, and provide references for previous submittals and NRC SER's for the convenience of the reviewer.The discussion of this attachment describes submittals for both units because much of the supporting analysis for unit 2 was performed to bound both units.Submittals primarily for unit 1 are sometimes supported by analyses bounding both units and/or include Technical Specifications modifications for unit 2.The following list summarizes the status of analysis features of earlier analyses: Princi al Features of the Earlier Anal ses Which Have Been Reviewed and A roved b NRC 1~2.3.4.5.6.Reduced temperature operation for unit 2.10%degradation for the RHR and HHSI pumps for both units.Increased MSIV response time for both units.BIT 0 ppm boric acid concentration for both units.Reduced temperature and pressure operation for unit 1.Reduced minimum measured flow for unit 1.Princi al Features of the Earlier Anal ses Which Have Been Submitted for Review But Have Not Been A roved (These features are proposed in the unit 1 increased steam generator tube plugging limit submittal, reference 30.)2.3.4, 5.10%degradation for the centrifugal charging pumps for both units.Minimum RWST temperature of 70~F for both units.Shutdown Margin requirement of 1.3%for both units.Proposals to increase operating margin for unit 1.Analysis to support operation of the spent fuel pool with one unit.operating at 3588 MWt Princi al Features of This unit 2 U rate Submittal 1.2.3.4.5.Unit 2 rerate to 3588 MWt.Increase the tolerance of pressurizer safety valve setpoint to 3%for unit 2.Increase OTaT/OP~T operating margin.Remove mixed core penalties.

15%degradation for safety injection and RHR pumps.Pu ose of the Earlier Anal ses Reratin Pro ram The earlier analyses were performed to accomplish a number of goals.The first of these was to permit operation of unit 1 at reduced primary temperature and pressure.The benefit of.operating in a reduced primary temperature and pressure mode was to slow the degradation of the unit 1 steam generators.

In addition, since essentially all of the analytic basis of the Cook Nuclear Plant units had to be reviewed or revised, analyses were performed to position unit 1 for subsequent uprating to 3413 MWt core power and unit 2 to 3588 MWt core power.The margin formerly intended to be allocated to a potential unit 1 uprate was subsequently allocated to an increased steam generator tube

Attachment 5 to AEP:NRC:1223 Page 3 plugging limit in the unit 1 increased steam generator tube plugging limit submittal, reference 30.The earlier analyses also supported increased operating margins in selected areas.Among these were increased allowable ECCS pump degradation, reduction of required shutdown margin (SDM), a reduction in the minimum temperature of the refueling water storage tanks (RWST), reduction to zero of the boron concentration in the boron injection tanks (BIT), and slower response times for certain components and systems which applied to unit 2.Descri tion and Review Histo of Prior Submittals This section describes the prior analyses for the Cook units in essentially chronological order with an emphasis on unit 2.The first of the earlier analyses is described in reference 1, WCAP-11908,"Containment Integrity Analysis for Cook Nuclear Plant units 1 and 2." It was submitted for NRC review by reference 2.Reference 1 presented a long term containment analysis which bounded both units at a core power of 3413 MWt, operation at a reduced temperature and pressure, and operation of the ECCS with residual heat removal (RHR)crossties closed.Since the analysis described in reference 1 was performed, two new long term containment integrity analyses have been performed for the Cook Nuclear Plant units.One was performed in conjunction with the proposal to increase the unit 1 steam generator tube plugging limit.It was performed at an NSSS power of 3425 MWt and is described in reference 29.Therefore, a new analysis was performed at an NSSS power of 3600 MWt.It is described in WCAP-14489 which is Attachment 6 to this submittal and reference 31.Neither of these new analyses has been reviewed at this time by the NRC.The next group of analyses is described in reference 3, WCAP-11902,"Reduced Temperature and Pressure Operation for Cook Nuclear Plant Unit 1 Licensing Report." Reference 3 presented the remainder of the analyses and evaluations necessary to support operation of unit 1 at reduced temperature and pressure.The NSSS systems and components analysis was performed for an NSSS power level of 3600 MWt.Reference 3 was submitted for NRC review by reference 4.The letters of references 5, 6, 7, and 8 provided supplementary information to the staff related to the request for approval (references 2 and 4)to operate unit 1 at reduced temperature and pressure.The request to operate unit 1 in this manner was approved by reference 9.Reference 10, WCAP 11902, Supplement 1,"Rerated Power and Revised Temperature and Pressure Operation for Cook Nuclear Plant Units 1&.2 Licensing Report", describes the balance of the analyses which were performed by Westinghouse Electric Corporation to support the operation of unit 1 at uprated power and reduced temperature and pressure.This report describes analyses and evaluations which were performed to bound both units at an uprated NSSS power of 3600 MWt.In particular, NSSS systems and components were evaluated for an uprated NSSS power of 3600 MWt for both units.The report also describes an analysis of the steam mass and energy release (SM&E)to containment, the associated containment analysis, and the SMRE

Attachment 5 to AEP:NRC:1223 Page 4 release outside containment.

These two analyses assumed a shutdown margin of 1.3%, an increased time response for main steam isolation, 0 ppm boron concentration in the boron injection tank (BIT), and were performed to bound both units at the unit 2 uprated core power of 3588 MWt.Since the SMGE to containment analysis described in reference 10 was performed, the SMRE to containment has been reanalyzed.

The new analysis also bounds both units at an NSSS power of 3600 MWt.Zt was performed in conjunction with the proposal to increase the unit 1 steam generator tube plugging limit.It is described in reference 29 and was submitted with reference 30.Reference 11,"Vantage 5 Reload Transition Safety Report for Cook Nuclear Plant Unit 2 (RTSR)", together with reference 1,"Containment Integrity Analysis for Cook Nuclear Plant units 1 and 2", reference 3, WCAP 11902, Reduced Temperature and Pressure Operation, and reference 10, WCAP 11902, Supplement 1, Rerated Power and Revised Temperature and Pressure Operation, support reduced temperature and pressure operation for unit 2 at an uprated core power of 3588 MWt.However, reference 1 and the RHR and HHSZ crosstie closed LOCA cases of reference 11 only support a unit 2 core power of 3413 MWt.The analyses reported in references 1, 10, and 11 support operation with Westinghouse fuel, 10%degradation of the CCP's, HHSZ pumps, and RHR pumps, an increase of 3 seconds in MSIV response time for unit 2, 0 ppm boric acid concentration in the BIT for unit 2, a minimum RWST temperature of 70'F for unit 2, and a SDM of 1.3%for unit 2.The letter of reference 13 submitted reference 11, RTSR, and the portions of reference 10, WCAP 11902, Supplement 1, which addressed the SMEE to the containment.

The letters of references 14, 15, and 16 provided supplementary information to the staff related to reference 13.Operation of unit 2 with Westinghouse fuel at reduced temperature, with 10%degradation of the RHR and HHSZ pumps, was approved by reference 17.Some changes to both the unit 1 and unit 2 Technical Specifications which returned certain activities to administrative control were also made.The letters of references 18 and 19 for unit 1 and unit 2 respectively proposed technical specifications that implemented an increase of 3 seconds in the MSZV response times.These proposals were supported by reference 3, WCAP-11902, for both units, reference 10, WCAP-11902, Supplement 1, for both units, reference 11, RTSR, for unit 2, and evaluations performed by us.The letters in references 18 and 19 submitted the portions of reference 10, WCAP 11902, Supplement 1, which addressed the SMEE to the containment.

The propo'sais to increase the MSZV response times by 3 seconds were approved by references 20 and 21.The letter of reference 22 proposed to reduce the primary system minimum measured flow (MMF)for unit 1.This proposal was approved by reference 23.The letter of reference 24 proposed to reduce the boron concentration in the BIT's of both units to 0 ppm.This proposal was supported by reference 3, WCAP-11902, reference 10, WCAP-11902, Supplement 1, reference 11, RTSR, and analyses performed by us.The AEPSC analysis of the impact of the steam line mass and energy release (SM&E)outside containment on the operability 4 fl Attachment 5 to AEP:NRC:1223 Page 5 of equipment in the main steam enclosures was described in reference 24.Reference 10, WCAP 11902, Supplement 1, was submitted in its entirety in support of this proposal.The proposal was approved by reference 25.The letters of references 26 and 27 proposed to relax the tolerance of the main steam safety valve (MSSV)setpoints for both Cook Nuclear Plant units.The proposal was based on new analyses and on evaluations performed by Westinghouse Electric Corporation.

The evaluations were based on the analyses described in reference 1, WCAP-11908,"Containment Integrity Analysis for Cook Nuclear Plant units 1 and 2", reference 3, WCAP-11902, reference 10, WCAP-11902, Supplement 1, and reference 11, RTSR.The descriptions of the new analyses and evaluations were included as attachments to these letters, references 26 and 27.The unit 2 SBLOCA analysis described in the MSSV submittal was performed assuming that the high head safety injection (HHSI)crossties were closed.It was performed at a core power of 3250 MWt.As a result provisions were included in the Technical Specifications which required a power reduction when the HHSI crossties are closed.In this submittal, a proposal to remove this provision is made based on a new SBLOCA analysis using new models.The new analysis is de'scribed in Attachment 6 of this submittal which is reference 31.The MSSV setpoint relaxation proposal was approved by reference 28.A recent submittal which impacts the proposal to uprate unit 2 is the proposal to increase the limit of unit 1 steam generator tube plugging.This submittal is reference 30.It has not yet been approved by the NRC.Reference 30 includes a revised steam mass and energy release to containment analysis which bounds both units at an NSSS power of 3600 MWt and proposals to increase operational margin for unit 2.The increases in operating margin include 10%head degradation for the centrifugal charging pumps, a reduction in the minimum refueling water storage tank temperature to 70oF, and a reduction in the required shutdown margin to 1.3't.Reference 30 also proposes to increase the pressurizer safety valve tolerance from 1%to 3%for unit 1 only.Two of the proposed changes in this submittal, AEP:NRC: 1223, is the addition of footnotes which requires that the as left magnitude of the pressurizer safety valves be 1%.This proposal was inadvertently omitted from Reference 30.Attachment 6 to reference 30 is reference 29, WCAP 14285, Revision 1,"Donald C.Cook Nuclear Plant Unit 1 Steam Generator Tube Plugging Program Licensing Report".In addition, this submittal r'equires the approval of previous submittals (references 32 and 33)in order to be implemented.

They have not yet been approved by the NRC.These submittals contain a"Refueling Operations Decay Time Technical Specif ication Amendment Request" permitting core of f load 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> after subcriticality.

The analyses for this proposal support the operation of one unit, Donald C.Cook Nuclear Plant unit 2, at a core power of 3588 MWt from a spent fuel pool thermal hydraulic point of view.The" final submittal for unit 2 is this submittal.

It proposes to uprate the core rated thermal power to 3588 MWt.It also proposes increases in unit 2 operating margin by increasing as Attachment 5 to AEP:NRC:1223 Page 6 found pressurizer safety valve setpoint tolerance to 3%, increasing the OT~T/OP~T operating margin, and increasing the analyzed safety injection and residual heat removal pump head degradation to 15%.Attachment 6 to this submittal is reference 31, WCAP 14489, Revision 1,"Donald C.Cook Nuclear Plant Unit 2, 3600 MWt Uprating Program Licensing Report".References 2.WCAP-11908, Containment Integrity Analysis for Cook Nuclear Plant Units 1 and 2, M.E.Wills, July 1988.Letter AEP:NRC:1024D, Containment Long Term Pressure Analysis to Support RHR Crosstie Closure, from M.P.Alexich to T.E.Murley, August 22, 1988.WCAP-11902, Reduced Temperature and Pressure Operation for Cook Nuclear Plant Unit 1 Licensing Report, D.L.Cecchett, and D.B.Augustine, October 1988.4, 5.6.Letter AEP:NRC:1067, Reduced Temperature and Pressure Program Analyses and Technical Specification Changes, from M.P.Alexich to T.E.Murley, October 14, 1988.Letter AEP:NRC:1067A, Supplemental Technical Specification Changes for Reduced Temperature and Pressure Program, from M.P.Alexich to T.E.Murley, December 30, 1988.Letter AEP:NRC:1067B, Additional Information on Reduced Temperature and Pressure Submittal:
