3. Identification of Spent Fuel Pool Water Levels BVPS dischargesirradiatedfuel to a singlespentfuel storagepool for eachunit. With the exceptionof limited time periodsfor maintenanceor non-refuelingoperations, administrativecontrolsmaintaingatesin the openpositionbetweenthe following pools:

spentfuel pool, fuel transfercanaland caskloadingpit. Thus,thesepools are normally inter-connectedand at the samewater level when the water level in the spentfuel pool is greaterthan 1 foot abovethe top of storedfuel seatedin the storageracks.

The water levelsfor the SFPfor the BeaverValley Stationwill be determinedbasedon the existingdesignattributes,commitments,and licensingbasisof the station. This is alsoconsistentwith the NRC andNEI requirements.Levelsthat areto be determined will be establishedas part of the final designandby the CompleteSFPInstrumentation Designmilestonein Section2, Schedule.The proposeddesignfor BVPS will be based on the following key spentfuel pool water levels:

Level 1 - Level adequateto support operation of the normal fuel pool cooling system Indicatedlevel on either the primary or backupinstrumentchannelfor Unit 1 of greater than a to-be-determined elevationplus the accuracyof the SFPlevel instrument channel,which is to be determined.

Indicatedlevel on either the primary or backup instrumentchannelfor Unit 2 of gteater than a to-be-determined elevationplus the accuracyof the SFPlevel instrument channel,which is to be determined.

BeaverValley PowerStationReliableSpentFuel Pool InstrumentationOverallIntegratedPlan Oncethe water level in the Unit I pool dropsbelow a to-be-determined elevation, water will no longer be extractedfrom the pool to be sentto Unit I SFP cooling equipmentto provideheatremovalfrom the Unit I SFP.

Oncethe water level in the lJnit? pool dropsbelow a to-be-determined elevation, water will no longerbe extractedfrom the pool to be sentto Unit? SFPcooling equipmentto provideheatremovalfrom the Unit 2 SFP.

Level2 - Level adequateto provide substantialradiation shieldingfor a person standingon the spent fuel pool operatingdeck Indicated level on either primary or backupinstrumentchannelof Unit I greaterthan 752'-0" plus the accuracyof the SFPlevel instrumentchannel,which is to be determined.This monitoringlevel ensuresthereis an adequatewater level to provide substantialradiationshieldingfor a personstandingon the SFPoperatingdeck.

Indicatedlevel on either primary or backupinstrumentchannelof Unit 2 greaterthan 752'-0" plus the accuracyof the SFPlevel instrumentchannel,which is to be determined.This monitoringlevel ensuresthereis an adequatewater level to provide substantialradiationshieldingfor a personstandingon the SFPoperatingdeck.

This level was selectedbasedon the NEI l2-02 Rev. I guidancefor selectingthe plant specificelevationfor Level 2 given as 10 feet (+/- 1 foot) abovethe highestpoint of any fuel rack seatedin the spentfuel pool.

Level3 - Level where fuel remainscoveredand actionsto implement make-up water addition should no longer be deferred Indicatedlevel on either the primary or backup instrumentchannelof Unit I greater than742'-0" (which is the top of the highestpoint on the spentfuel pool racks)plus the accuracyof the SFPlevel instrumentation,which is to be determined.This monitoring level assuresthat there is adequatewater level abovethe storedfuel seatedin the rack.

Indicatedlevel on either the primary or backup instrumentchannelof Unit 2 greater than742'-0" (which is the top of the highestpoint on the spentfuel pool racks)plus the accuracyof the SFPlevet instrumentation,which is to be determined.This monitoring level assuresthat thereis adequatewater level abovethe storedfuel seatedin the rack.

4. Instruments The planneddesignfor the SFPlevel systeminstrumentationsatisfiesthe requirements and guidelinesof NRC JLD-ISG-2012-03and NEI 12-02Rev. I as discussedbelow.

Both the primary and backupinstrumentchannelswitl consistof fixed components.The plan is for both channelsto utilize guided wave radar,which functions accordingto the principle of time domainreflectometry.A generatedpulseof electromagnetic energy

BeaverValley PowerStationReliableSpentFuel Pool InstrumentationOverallIntegratedPlan travels down the probe. Upon reachingthe liquid surface,the pulse is reflected and based upon reflectiontimes, level is determined.Guidedwave radarattributes:

Cableassemblyis a fixture locatedcloseto the operatinglevel floor that suspendsa cableinto the pool. The guidedwave radarcableassemblyis smaller, andthereforeeasierto protectfrom eventgeneratedmissilesor falling objects.

Guided wave radar is effectively immuneto interferenceasthe signal staysin the immediatevicinity of the wire antenna.As the cableassemblywill be located closeto the pool wall it is betterprotectedfrom interferencefrom foreign objects.

This technology is immuneto the changesin temperatureor the specific gravity of the SFPwater.

Measuredrangewill be continuousfrom the top of the SFPto the top of the spentfuel racks.

5. Reliability Reliability of the primary and backup instrumentchannelswill be assuredby conformancewith the guidelinesof NRC JLD-ISG-2012-03andNEI 12-02,Rev. 01.

Reliability will be ensuredthroughpropermounting,arrangement, qualification,testing, maintenanceand calibrationof the primary and backupinstrumentchannelsas discussed below.

6. Instrument Channel Design Criteria Instrumentchanneldesigncriteriawill be consistentwith the guidelinesof NRC JLD-ISG-2012-03 andNEI 12-02Rev. l.

7. Arrangement The planneddesignof this systemwill consistof two measurement channels,oneprimary and one backup. Eachchannelconsistsof a level sensor,an electronicsunit and an indicator. The primary and backupinstrumentchannelsensorswould be protected againstmissilesthat may resultfrom damageto the shuctureover the SFP. The sensors will be mountedas closeto the differentSFPcornersas possibleto minimize the possibilityof a singleeventor missiledamagingboth channels.The sensorarrangement hasbeenproposedin a mannerlimiting any interferencewith existingequipmentin or aroundthe SFP. This proposeddesignwould not poseany potentialhazardtopersonnel working aroundthe pool or on the level instrumentationitself.

The proposeddesignlocatesthe electronicsenclosuresin an arearemovedfrom the SFP environment,which would be accessiblein the eventof a beyond-designbasisexternal eventthat would restrict accessto the SFP. The enclosuresfor the two instrument channelswill be separatedto minimize the possibilityof a singleeventdamagingboth

BeaverValley PowerStationReliableSpentFuelPool InstrumentationOverallIntegratedPlan channels. Cabling for eachchannelwill be run in separateconduit and/or cabletray to the control room indicators.

8 . Mounting Installed primary and back up SFP level instrumentchannelequipmentwithin the spent fuel pool shall be mountedto retain its designconfiguration during and following the maximumseismicgroundmotion consideredin the designof the spentfuel pool structure in accordancewith NRC JLD-ISG-2012-03andNEI 12-02Rev. I guidance requirements.

9 . Qualification The primary and backupinstrumentationfor the proposeddesignwill be suitableand reliableat temperature,humidity, and radiationlevelsconsistentwith the SFPwater at saturatedconditionsfor an extendedperiodof time. This reliability will be established through use of an augmentedquality assuranqeprocess. Using the guidanceof NEI L2-02Rev. I andNRC JLD-ISG-2012-03the equipmentdesignwill includereliability againsteffectsof shockandvibration and seismicmotion.

The designwill considerthe environmentalconditionsas discussedby NEI 12-02,Rev. 1 which recommendsconsideringtemperature,humidity, and radiationlevelsduring normal operationand after an extemal beyonddesignbasisevent for no fewer than seven dayspost-eventor until off-siteresourcescanbe deployedby the mitigating strategies.

Conditionsconsideredarethe radiologicalconditionsfor a normal refuelingquantityof freshly discharged(100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />)fuel with SFPwater level at Level 3 as definedby NRC OrderEA-12-051,temperatures of 212"Fand 100%relativehumidity, boiling water and/or steam,and concentratedboratedwater.

The sensorelementsof the guidedwave radarapproachwill consistsolely of special cablethat will not be negatively impactedby the environmentalconditions described.

The electronicenclosureswill be mountedin an areaoutsidethe SFPareathat is accessibleby personnelafter an externalbeyonddesignbasiseventand is expectedto be a mild environment.The analogindicatorwill be mountedin the main control room, and as suchwill be suitablefor the environmentalconditionsof the main control room following an externalbeyonddesignbasisevent.

10. Independence The primary instrumentchannelwill be independentof the backupinstrumentchannel.

The primary and backupinstrumentchannelswill be physicallyand electricallyseparated to maintain channelindependence.The sensorswill be separatedas far apartas practical within the constraintsof existing pool geometryand equipment. Electronicsenclosures will be separatedby a suitabledistanceor may utilize structuralfeaturesof the room in

BeaverValley PowerStationReliableSpentFuel Pool InstrumentationOverallIntegratedPlan which they are locatedas a barrierto provideprotectionagainsta singleevent(missile, explosion,etc.)from damagingthe electronicsof both instrumentchannels.Powerwill be suppliedfrom two separatepower busesat a minimum, with a preferenceof different power divisionsor channelsas available. Cablingwill be run in separateconduitand/or cabletray. The sametechnologywill be usedfor both the primary and backup instrument channels.

I l. Power Supplies Eachchannelwill normally be poweredfrom independent720VAC power sourcesand will have a dedicatedbattery backup.A minimum battery life of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> will be providedto allow for power restorationfrom portableequipment.

12. Accuracy The guidedwave radardesignprovidescontinuousmonitoringof the SFPwater level.

The accuracyof the SFPlevel instrumentchannel,from sensorto main control room indicator,will be consistentwith the guidelinesof NRC JLD-ISG-2012-03and NEI 12-02,Rev. 1. Instrumentchannelswill be designedto maintaintheir design accuracywithout recalibrationfollowing a power interruption or changein power source.

13. Testing Testingwill be consistentwith the guidelinesof NRC JLD-ISG-2012-03and NEI 12-02,Rev. l. The instrumentchanneldesignwill includeprovisionsfor routine testingand calibration. The instrumentationwill allow for in-situ testingand calibration of the level instrumentationto minimize calibrationeffort and instrumentdowntime.

Calibrationprocedureswill be developedin accordancewith plant proceduresandvendor recommendation.

14. Display The displaywill be consistentwith the guidelinesof NRC JLD-ISG-2012-03and NEI l2-02 Rev. 1. Trainedpersonnelwill, at a minimum, be ableto monitorthe SFP water level from an appropriateand accessiblelocation, and will provide on demandor continuousindicationof SFPwater level. The SFPlevel instrumentationwill providefor displayof fuel pool level using an indicatorlocatedin the main controlroom. The indicatorwill be poweredby the instrumentloop andwill not requireadditionalpower circuits from thosedescribedabove.

BeaverValley PowerStationReliableSpentFuel Pool InstrumentationOverallIntegratedPlan 15.Instrument ChannelProgram Criteria:

15.1. Training The SystematicApproachto Trainingwill be utilized when developingand implementingtraining. Training for maintenanceand operationspersonnelwill be developedand provided.

t. Introduction On March 12,20L2,the NuclearRegulatoryCommission(NRC) issued Order EA-12-05l, Order ModifuingLicenseswith Regardto ReliableSpentFuel Pool Instrumentation.Order EAl2-051 requireslicenseesto "have a reliableindicationof the water level in associatedspentfuel storagepools capableof supportingidentification of the following pool water level conditionsby trainedpersonnel: 1) level that is adequate to supportoperationof the normalfuel pool cooling system,2) level that is adequateto provide substantialradiationshieldingfor a personstandingon the spentfuel pool operatingdeck,and 3) level wherefuel remainscoveredand actionsto implementmake-up water additionshouldbe no longerdeferred." OrderEA-12-051alsorequiresall holdersof operatinglicensesissuedunder 10 CFR Part 50 to submitto the Commission for review an overall integratedplan, includinga descriptionof how compliancewith OrderEA-12-051requirementswill be achieved,by February28,2013.

The NRC issuedJapanLessons-Learned ProjectDirectorate,JLD-ISG-2012-03, Compliancewith Order EA-L2-051,ReliableSpentFuel Pool Instrumentation, Revision0, datedAugust 29,2012,that endorseswith exceptionsand clarifications,the methodologiesdescribedin NuclearEnergyInstitute(NEI) NEI 12-02,Industry Guidancefor Compliancewith NRC Order EA-12-051, "To Modify Licenseswith Regard to ReliableSpentFuel Pool Instrumentation," Revision 1, datedAugust 24,2012.

3. Identification of Spent Fuel Pool Water Levels PNPPdischargesirradiatedfuel to a singlespentfuel storagepool. With the exceptionof limited time periodsfor maintenanceor non-refuelingoperations,administrativecontrols maintaingatesin the openpositionbetweenthe following pools: fuel storage&

preparationpool, fuel transferpool, spentfuel storagepool, and caskpit. Thus,these pools are nonnally inter-connectedand at the samewater level when the water level in the spentfuel pool is greaterthan 3.5 feet abovethe top of storedfuel seatedin the storageracks. The water levels for the SFPfor the Peny Stationwill be determinedbasedon the existingdesignattributes,commitments,and licensingbasisof the station. This is also consistentwith the NRC JLD-ISG-2012-03andNEI 12-02requirements.The proposed designfor PNPPis basedon the following key spentfuel pool water levels: Level 1 - Level adequateto support operationof the normal fuel pool cooling system Indicatedlevel on either the primary or backupinstrumentchannelof greaterthan elevation619'-6" plus the accuracyof the SFPlevel instrumentchannel,which is to be determined.The highestpoint on the spentfuel pool racksis at elevation591'-4". This level is basedon the elevationof the skimmersthat will preventwatertransfer from the SFPto the SurgeTanks that feed normal spentfuel pool cooling. Oncethe water level in the pool dropsbelow elevation619'-6", water will no longerbe extracted from the pool to be sentto SurgeTanks to provide water make up for SpentFuel Pool Cooling. Level 2 - Level adequateto provide substantialradiation shieldingfor a person standingon the spent fuel pool operatingdeck Indicatedlevel on eitherprimary or backupinstrumentchannelof greaterthan6074" plus the accuracyof the SFPlevel instrumentchannel,which is to be determined.This monitoring level ensuresthere is an adequatewater level to provide substantial radiationshieldingfor a personstandingon the SFPoperatingdeck. This level was selectedbasedon the NEI 12-02Rev. I guidancefor selectingthe plant specificelevationfor Level 2 given as l0 feet (+/- 1 foot) abovethe highestpoint of any fuel rack seatedin the spentfuel pool. This level will provide adequateradiation shieldingfor a personstandingon the spentfuel pool operatingdeck from the fuel in the pool. However,the Perry SFPcontainsothermaterialscapableof providing sufficientdosesuchthat the pool deckwould not be inhabitableshouldthe materialsbe uncovered.The detaileddesignwill updateor developapplicableplant proceduresto addressactionsrequiredto addressradiologicalconditionscreateddue to the stored radioactivematerial.

PerryNuclearPowerPlantReliableSpentFuel Pool InstrumentationOverallIntegratedPlan Level3 - Level where fuel remainscoveredand actionsto implement make-up water addition should no longer be deferred Indicatedlevel on either the primary or backupinstrumentchannelof greaterthan 594'-6" plus the accuracyof the SFPlevel instrumentation, which is to be determined. This monitoringlevel assuresthat thereis adequatewater level abovethe storedfuel seatedin the rack. The top of the highestpoint on the spentfuel racksis locatedat 591'-4'0.The top of the gate seatthat separatesthe two pools containing spentfuel (the fuel storageand preparationpool and the spentfuel storagepool) from the fuel transferpool is at elevation594'-6' . Oncethe water dropsbelow this point, the singleSFPhas effectivelybeensegregated into four separatepits. Consequently,594' -6" is the level at which actionsto initiatewater make-upwill not be further delayed.This settingis in compliancewith the Order; however,it representsa slight variation to the NEI guidance.The NEI guidancerecommendsusingthe top of the highestfuel rack in the spentfuel pool as level 3. The conditionsdescribedabovemakeit undesirableto use top of the highestfuel rack as level 3. This is a conservativedecisionto treat 594'-6" as top of the fuel and necessaryto ensureproper actionsare taken in the event that one of the channelsof SFPlevel instrumentationis lost or in the eventthat level is decreasing due to a hole in one of the pools.

4. Instruments The planneddesignfor the SFPlevel systeminstrumentationsatisfiesthe requirements and guidelinesof NRC JLD-ISG-2012-03and NEI 12-02Rev. I as discussedbelow.

The instrumentationwill consistof permanent,fixed primary and backup instrument channels.The plan is for both channelsto utilize guidedwave radar,which functions accordingto the principle of time domainreflectometry.A generatedpulseof electromagnetic'energy travelsdown the probe. Upon reachingthe liquid surfacethe pulseis reflectedandbasedupon reflectiontimes level is determined.Guidedwave radar attributes: Cableassemblyis a fixture locatedcloseto the operatinglevel floor that suspendsa cableinto the pool. The guidedwave radarcableassemblyis smaller, andthereforeis easierto protectfrom eventgeneratedmissilesor falling objects. Guided wave radar is effectively immuneto interferenceasthe signal staysin the immediatevicinity of the wire antenna.As the cableassemblywill be located closeto the pool wall it is betterprotectedfrom interferencefrom foreign objects. This technology is immuneto the changesin temperatureor the specific gravity of the SFPwater. Measuredrangewill be continuousfrom the top of the SFPto the top of the spentfuel racks.

s. Reliability Reliability of the primary and backup instrumentchannelswill be assuredby conformancewith the guidelinesof NRC JLD-ISG-2012-03andNEI 12-02,Rev. 01.

Reliability will be ensuredthroughpropermounting,affangement,qualification,testing, maintenanceand calibration of the primary and backup instrumentchannelsas described below.

6. Instrument ChannelDesignCriteria Instrumentchanneldesigncriteriawill be consistentwith the guidelinesof NRC JLD-ISG-2012-03andNEI 12-02Rev. l.

The fuel storage& preparationpool and the spentfuel storagepool are the only pools that containspentfuel racks.The caskpit andthe fuel transferpool do not hold spentfuel. Additionally, the gatesthat separatethe fuel storageand preparationpool and the spent fuel storagepool from the fuel transferpool havenot beeninstalled in more than 15 years andwill requireevaluationto be re-installed.Therefore,thesepools aretreatedas one pool with regardto this Order. The designof the fuel transferpool and its gatesis suchthat thereis an approximate3.5 foot gap betweenthe top of the fuel racks in the two pools containing spentfuel (the fuel storage& preparationpool and the spentfuel storagepool) and the top of the fuel transfer pool gateseat. As a result,the top of the fuel transferpool gateseat(approximately3 feet abovethe fuel racks)will be usedasLevel 3. This settingis in compliancewith the Order;however,it representsa slight variationto the NEI l2-02, Rev. I guidance(which recommendsusingtop of the fuel racksfor level 3). This is a conservativedecisionand it will ensurethat actionsare taken to preventthe spentfuel from being uncovered.

7. Arrangement The planneddesignof this systemwill consistof two measurement channels,oneprimary and one backup. Eachchannelwill consistof a level sensor,an electronicsunit and an indicator. The primary and backupinstrumentchannelsensorswill be protectedagainst missilesthat may result from damageto the structureover the SFP. The sensorswill be mountedat the westernend of the fuel pool (the fuel preparationand storagepool), but as closeto the adjacentcornersas possibleto minimize the possibilityof a singleeventor missiledamagingboth channels.The sensorarrangement hasbeenproposedin a manner limiting any interferencewith existingequipment in or aroundthe SFP. This planned designis conservativeand is in compliancewith OrderEA-12-051however,it does representa minor deviationfrom the NEI Guidance.The NEI Guidancerecommends putting instrumentationin opposite(diagonal)endsof the spentfuel pool. Due to the limited available locations(causedby interference)for installation,the instrumentation cannotbe installedon opposite(diagonal)endsof the pool. This planneddesignwill also not poseany potentialhazardto personnelworking aroundthe pool or on the level instrumentationitself.

PerryNuclearPowerPlantReliableSpentFuel Pool InstrumentationOverallIntegratedPlan The proposeddesignlocatesthe electronicsenclosuresin an arearemovedfrom the SFP environment,which would be accessiblein the eventof a beyond-designbasisexternal eventthat would restrictaccessto the SFP. The enclosuresfor the two instrument channelswill be separatedto minimize the possibilityof a singleeventdamagingboth channels. Cabling for eachchannelwill be run in separateconduit and/or cabletray to the control room indicators. 8 . Mounting Installedprimary andback up SFPlevel instrumentchannelequipmentwithin the spent fuel pool shall be mountedto retainits designconfigurationduring and following the maximum seismicgroundmotion consideredin the designof the spentfuel pool structure in accordancewith NRC JLD-ISG-2012-03andNEI 12-02Rev. I guidance requirements. 9 . Qualification The primary and backup instrumentationfor the proposeddesignwill be suitableand reliable at temperature,humidity, and radiation levels consistentwith the SFPwater at saturatedconditionsfor an extendedperiodof time. This reliability will be established through use of an augmentedquality assuranceprocess. Using the guidanceof NEI 12-02Rev. 1 andNRC JLD-ISG-2012-03,the equipmentdesignwill include reliability againsteffectsof shockandvibration and seismicmotion. The designwill considerthe environmentalconditionsas discussedby NEI 12-02,Rev. I which recommendsconsideringtemperature,humidity, and radiationlevelsduring normal operationand after a beyonddesignbasisexternalevent for no fewer than seven dayspost-eventor until off-site resourcescan be deployedby the mitigating strategies. Conditionsconsideredarethe radiologicalconditionsfor a normal refuelingquantityof freshly discharged(100 hours)fuel with SFPwater level at Level 3 as definedby NRC OrderEA-12-051,temperatures of 2l2oF and 100%relativehumidity,boiling water and/or steam,and concentratedboratedwater. The sensorelementsof the guidedwave radarapproachwill consistsolely of special cablethat will not be negativelyimpactedby the environmentalconditionsdescribed. The electronicenclosureswill be mountedin an areaoutsidethe SFPareathat is accessibleby personnelafter a beyonddesignbasisexternaleventand is expectedto be a mild environment.The analogindicatorwill be mountedin the main control room, and as suchwill be suitablefor the environmentalconditionsof the main control room following a beyonddesignbasisexternalevent. The vendorsuppliedsensorsand associatedelectronicswill be requiredto be testedand qualified for shockandvibration as a result of a beyonddesignbasisexternalevent. Seismicqualificationof equipment will be equivalentto the maximumgroundmotion spectrumfor the areain which it is to be installed.
