Theveepholewasusedtodraincondensation neartheinstrument whichmayhaveaccumulated insidetheflexconduitduringthesimulated DBAtest(seeattachedsketches).

TheDCCNPinstalled configuration incorporated theuseofasealtiteflexibleconduitplusthesealingofboththeentranceandexitoftheflexibleconduitwithanRTVsiliconesealant.Noprovisions foraweep-hole weremadefortheDCCNPspecificdesign.Theapplicable plantdesignstandardfortheinstallation oftheinstrument,

Thesealtiteflexibleconduitusedintheinstallation istradenamed Liquatite andmanufactured bytheAlflexCo.TheplasticcoveringovertheflexiblemetalconduitismadeofaPolyvinyl Chloride(PVC)material.

According tothemanufacturer, theLiquatite flexconduithasnotbeenenvironmentally qualified.

Thehypothesized failuremodeoftheD.C.Cookconfiguration isthatthePVCjacketonth'eflexconduitmayfailduringanaccidentnearanyelevatedpointontheconduitandallowsteamtoenterandcondense.

Thecondensation vouldthem"pool"attheconduitlowpoints,therebysubjecting thepigtailstopossiblesubmergence.

Thefollowing paragraphs ofthismemoaddressthisconcern.IHTRA-SYSTEM Throughconversations withFoxboro,ithasbeendetermined thattheintentoftheweep-hole wastoavoidthe"backing-up" ofcondensate fromthechemicalsprayintotheIntegralJunctionBoxusedinoneofthetwotestedconfigurations.

Theintegraljunctionboxhousesaterminalblockwhichisknowntobesusceptible toleakagecurrentswhenexposedtochemicalspraysolution.

Theweep-hole designwascarried-over tothesecondconfiguration whichwasusedatD.C.Cook.Thesecondconfiguration incorporates aninternalinstrument splicetoaConaxsealassembly.

withnoIntegralJunctionBoxorterminalblockinstalled.

Therefore, the"backing-up" ofcondensate neartheinstrument sealassemblyintheD.C.Cookconfiguration wasofnosignificant concern.Additionally, inbothtestedconfigurations themetalflexconduitloopedbackupaftertheweepholeandwasrouteddowntoapenetration atthebottomofthetestchamber.Thebottomendoftheflexconduitwassealedwhichcreatedapotential forthe"pooling" ofchemicalspraycondensate duringthetest.Inthisrespect,thetestedconfiguration issimilartowhatishypothesized intheD.C.CookPlantconfiguration.

Thepotential forpigtailsubmergence failureismuchlessofaconcernfortheD.C.Cookconfiguration duetothefollowing reasons:1).ItisnotlikelythattheD.C.Cooksealedflexconduitconfiguration wouldfailinsuchawayastocreateaharsherchemicalsubmergence environment forthepigtailsthanwhatwastested.Thetypeofsubmergence inthespeculated D.C.Cookcaseinvolvesasteamcondensate andisnotassociated withcontainment floodingconditions.

Thesteamcondensate shouldtheoretically beatapHvaluewhichislessseverethanthechemicalsprayexposureduringthetest.2)TheKapton-insulated pigtailwiresoftheConaxSealassemblyareindividually protected bytheapplication ofaheatshrinkable polyolefin jacket.Theheatshrinktubingjacketsignificantly improvestheabilityofthepigtailwirestowithstand chemicalsubmergence byaddingaprotective layerofmaterialover.theKaptoninsulation.

Whereapplied,theprotective layerofheatshrinkreducestheexposureoftheKaptoninsulation tothecondensate.

ThetypicalfailureofKaptoninsulated wireisduetoanabrasionoftheinsulating materialduringinstallation combinedwiththeeffectsofthechemicalsolution.

Thepotential forabrasionorothermechanical damageoftheKaptoninsulation duringinstallation atD.C.Cookhasbeenessentially eliminated bytheapplication oftheheatshrinkjacket.

1 5)Thetestreportconfiguration, whichexposedtheKaptoninsulated pigtailstothetestchamberenvironment viathe1/4inchweephole,demonstrates theabilityofthepigtailwirestowithstand harshchemicalconditions evenwithoutaprotective heatshrinkjacket.Inconclusion, webelievethattheomittance oftheweep-hole intheflexconduitneartheinstrument intheD.C.Cookconfiguration doesnothaveadetrimental impactontheenvironmental qualification oftheinstrument, sealassemblyorsealassemblypigtails.

Inaddition, webelievethatthereisnosignificant functional difference betweenthetestedandtheD.C.Cookinstalled configurations ofthefoxboroinstrument pigtailconduits.

~pSsi~+Xo~Gg-HUGIENotice86-03identifies potential problemswiththeenvironmental qualification oftheinternalcontrolwiringinthelimitorque motoroperators.

C/R2-03-86-295 reportsthatajumperwirewasfoundduringtheMOVwalkdownwhichwasnotlistedasanacceptable environmentally qualified wireinmymemototheplantdated1/9/86.Thepurposeofthismemoistodetermine typicalvalveoperability inlightofthecontrolwirequalification uncertainties.

Thecontrolwiringinquestionislocatedcompletely withintheLtmitorque operator's limitswitchcompartment andisusedtointerconnect torqueandlimitswitches.

ForD.C.Cook,terminalblocksarenotinstalled orusedinsidethecompartment.

Instead,fieldcableisdirectlyterminated ontotheswitcheswithinternaljumperwiringproviding anyadditional interconnections.

TheMOVcontrolcircuitvoltageisungrounded 220VACor250VDC.Thepostulated controlwirefailuremodesareopen-circuits, single-wire groundsandwire-to-wire shortswhich,depending onthecircumstances explained below,maycauseinadvertent orincorrect operation oftheassociated MOV.Opencircuitsorhighresistance connections arenormallyattributed toincorrect termination ofthecontrolcircuitwiringandwillgenerally notoccurasaresultofextremeenvironmental conditions, TheinternalwiringofanMOVisprotected bythelimitswitchcompartment coverfromdirectsprayimpingement duringanaccidentwhichcouldtheoretically loosenacontrolwireandcreateanopencircuit.Circuitshortsandgrounds(including bothhighimpedance/leakage currentorlowimpedance/direct shortconditions) mayhypotehtically occurasaresultofgrosselectrical insulation breakdown orasaresultofinsulation leakagecurrentssufficient tocausemisoperation ofthevalvecontrolcircuit.FortheDCCNPcontrolvoltagelevels,grosselectrical breakdown couldonlyoccurondirectconductor-to-conductor orconductor-to-ground contact.Electricarc-overishighlyunlikelyatlowvoltagelevelsduringnormaloperation oftheMOV.Directshortsarepossibleonlywhereconductor breakthrough occursasaresultof'severecableinsulation IHTRA~SYSTEM 1

Basedontheievegeneenericproperties ofpossiblejumperwiringatDCCNP,webelthatthistypeofextremedegradationshouldnotoccurunderspecified accidentconditions.

Theconfiguration oftheindividual controlwireswithinthelimitswitchcompartment greatlyminimizes theprobability ofthelnvlndividual conductors achieving contactwithgroundedcomponents

~Wororotherexposedconductors.

Mostjumpersarelessthanafeincheslong,especially betweenlimitswitchtermination poins.tExcesswireisnormallykepttoaminimumwiththemajorityofwirestakingadirectpathbetweenterminalpointsthusr'educing thelikelihood ofelectrical contact.Thegeneralconstruction ofthelimitswitchandtorqueswitchinsulating blocksalsoreducestheexposureofpossibleelectrical contactswithrecededterminalpoints.Althoughconductor breakthrough shouldnotoccur,sufficient insulation degradation maycausechangesintheindividual wireinsulation resistances forsevereenvironments.

Whilesuchchangescouldresultinthewire'sinability toadequately passahighvoltagewithstand testperformed aspartofthequalification (e.g.IEEE-383),

thesechangesareunlikelytocausesignificantly lowconductor-to-conductor orconductor-to-groundInsulation Resistance (IR)valuesnecessary tocauseMOVfailureormisoperation.

Thephysicalwireseparation mentioned abovecreateslongleakagecurrentpathswhicheffectively insurethatlowIRvalveswillnotoccur.Furtherreducingtheprobability ofMOVmisoperation duringanaccidentisthatalargepercentage ofinstalled jumperwiringisenvironmentally qualified wireasexplained inmymemotoA.A.Blind-DCCNPdated1/9/86.(Attached)

Additional justification forsafecontinued operation isthefactthattheDCCNPMOVcontrolcircuitvoltagesareungrounded.

Ungrounded or"floating" voltagesystemstypically allowasingleconductor togroundfaultwithouthavinganimpactonthecontrolcircuit.Onlywhentwosimsultaneous conductor-to-ground (i.e.conductor-to-conductor) faultsoccurwouldtherebeachanceformisoperation oftheMOV.Thepossibility ofspuriousoperation ofMOV'sduetoshortcircuitsisalsominimized byAEP~sdesignphilosophy ofdoublebreakingofthecontrolcircuit.Thedoublebreakconceptrequirescontrolcontactstobelocatedatbothpolarities oftheactuating circuit.Withthisconfiguration andungrounded controlvoltages, ashortcircuittogroundofasingleinternaljumperwireoftheMOVcannotcauseaspuriousoperation ofthevalve.

Finally,itshouldbenotedthatintheunlikelyeventthatwiredegradation effectsMOVoperability, remotevalverepositioning canbeaccomplished fromthevalvecontrolcenter.Manualactuation ofthemotorcontactor canadequately reposition theaffectedvalveassumingtheVCCisaccessible luringthepost-DBE.

DearMrDrab:

Aswe'avepreviously discussed, oneofthelatestenvironmental qualification uncertainties involvestheUseof"T-drains" onLimitorque actuatormotors~NeededfromLimitorque isaclarification onthequalification requirements fortheuseofT-drains.

Specifically, thefollowing concernsneedtobeaddressed:

1.InwhichLimitorque environmental qualification testreportswereT-drainsinstalled onmotors?2.WhataretheT-drainrequirements withrespecttoinsideversusoutsidecontainment buildingvalvemotoroperators?

Weunderstand thatLimitorque haaqualified actuators withandwithoutT-drainsinstalled inthemotors.Doyou"considertheT-drainstobeanabsolutequalification requirement oradesignenhancement, especially sincesomeactuatora werequalified withoutT-drains?

Ifrequired, doyourecommend thatallactuatormotorshaveT-drainsinstalled, evenwhereT-drainholesarenotavailable?

4.Whatarethespecifictechnical reasonsfortheinstallation ofT-drains?

Cantherebeplant-specific actuatorconfigurations inwhichT-drainsarenotrequired.

Forexample,woulditbepossibleforthecondensate todrainoffthroughotheravenues.
