Alistofsuchcompo-nentswasdeveloped basedonthesystemelimination criteriapre-sentedinSection2.1andthecomponent elimination criteriaidentified inSection2.2ofthisreport.HELBzonescontaining bothcontrolsystemscomponents ofinterestandHELBlocations weredefinedusingtheappropriate Equipment Qualification Environmental DesignCriteria(EQEDC)zonemapsasaguide,asdescribed inSection2.4ofthisreport.EachHELBzonewasanalyzed, theresultssummarized, andfinalconclusions andrecommendations arepresented inSection4.0.SUMMARYAsystematic studyhasbeenconducted todetermine theconse-quencesofpostulated HELBsandtheireffectsonnonsafety-relatedcontrolsystemcomponents locatedintheaffectedzone.Thedetailedanalysis(Appendix D)describes eachofthepostu-latedHELBeventsandtheirlimitingeffectsonthereactorpa-rameters.

5.CombinetheeffectsoftheHELBwithpotential, simultaneous malfunctions ofcontrolsystemcomponents inthepostulated HELBzoneanddetermine theeffectsonthecriticalreactorparameters.

Thefollowing elimination criteriaareappliedtotheremaining components toarriveatthefinallistofcomponents considered inthedetailedHELBanalysis.

2.Mechanical components (e.g.,structural steel,tanks,pipes,valves)arenotconsidered controlsystemscomponents sub-jecttofailure.However,instrument tapsandtubingforcomponents ofinterest, whichmaybephysically "locatedonmechanical components, are,included.

Thisincludespositionswitchesonair-andmotor-operated valveswhicharenotinterlocked withotherequipment.

4.Components thatprovideonlyindication and/orinputsforalarmsorrecording devicesareeliminated.

Ingeneral,initiating typecontrolcomponents, suchaselements,

Alistofcomponents whichhavebeenconsidered foranalysisbasedontheabovecriteriaandtheircontrolfunctions arein-cludedinAppendixB.2.3HIGHENERGYPIPECRITERIAThecriteriafordetermining highenergylinesusedinthestudywerebasedoncriteriaestablished inSection3.6oftheNMP2FSAR.Highenergypipingisdefinedasthosefluidsystemsthatduringnormalplantconditions, eitherareinoperation oraremaintained pressurized underconditions whereeither'orbothofthefollowing aremet:1.Maximumoperating temperature exceeds2004F2.Maximumoperating pressureexceeds275psigThosehighenergylinesthatoperateabovetheselimitsforlessthan2percentofthetimeandare,requiredtoperformtheirin-tendedfunctionareclassified asmoderate.energylinesand,therefore, areexcludedfromthescopeofthisstudy.Pipingwhosediameteris1-in.NPSorsmallerisalsoexcluded.

ZonemapsareprovidedinFigures1through6attheendofthereport.Thesacrificial approachusedthroughout theanalysisassumedthatanyHELBwithinadefinedzonewouldimpactallcontrolsystemcomponents inthezone.BecauseofthelargeareacoveredbyZoneD,thepotential impactofalinebreakwasfurtheranalyzedtoverifyifabreakatoneendoftheturbinebuildingcanrealistically failnonsafety gradecomponents locatedattheotherendwithintervening

pressure, radiation) areenveloped byemploying thesacrificial approach.

Thesacrificial approachassumesthatanyHELBwithinthede-finedzonewouldadversely impactallcontrolsystemscorn"ponentsinthezone.Usingthisapproach, environmental effectsareenveloped inthedetailedanalysispresented inAppendixD.Theturbinegenerator electrohydraulic system(TMB)isahighpressure, lowtemperature systemwithalimitedvolumeofEHliquidmaintained at"high.pressurebyasmallcapacitypump.Itisinconceivable thatapipebreakinthissystemwillincapacitate allnonsafety gradeinstruments inthezonesofTMBsystempiperouting,andanexception tothesacrificial approachinthiscaseisconsidered justified.
