Therotorwasbalancedand,asisnormalpractice, thestatorwasvarnished andtheendwindingspainted.ThereisconcernaboutthestatusoftheClassIEqualification ofthismotorasaresultoftheuseofnon-certified materials usedtovarnishthestator.Thechemicalcompatibility ofthenewlyaddedvarnishwiththeoriginalmaterials isunknown.AtwophaseprogramwasproposedtoAmericanElectricPower(AEP).byBattelletoresolvethesequestions.

PhaseI,AnalysisofMaterials, involvesasearchforinformation anddatatodemonstrate thatthenewlyaddedmaterials andtheoriginalmaterials arecompatible, andthatthemotorremainsqualified forClass1Eservice.PhaseII,Materials qualification, involvestheirradiation ofacombination oftheoriginalstatormaterials andthenewlyappliedmaterials todemonstrate thatthere.isnoadversereactiontoradiation.

ThisistheFinalReportforPhaseI.Thefollowing sectionscontainasummaryoftheworkperformed, conclusions, andrecommendations forfurtheractionbyAmericanElectricPower.Thefinalsectionofthisreport,Materials AnalysisOetails,providespermanent documentation oftheinforma-tionlocatedandhighlights theinformation thatsubstantiates thecon-clusions.

Thefinalsection,Materials AnalysisOetails,islengthyandisdirectedtowardthosepersonswithadetailedinterestintheeffectsof"radiation onorganicmaterials.

SUMMARYTheobjective ofthePhaseIanalysisofthematerials wastodetermine ifthevarnishandpaintaddedtothemotorhaveanyadverseeffectontheoriginally qualified materials andthequalification ofthemotor.Thefirststepwastoobtaininformation aboutthematerials usedbythemotormanufacturer, Westinghouse, andtheshopwhichbalancedandvarnished themotor.Thetwomaterials usedbyWestinghouse wereidentified as:Item818-6-665,AirOryInsulating Enamel-Epoxy,andItemd28-172EpoxyVarnish.Theinformation aboutthematerials usedbyWestinghouse wasproprietary andwasobtainedonlyafterBattellehadenteredaconfidential information agreement withWestinghouse.

Theshopthatbalancedthemotorusedmaterialmanufactured bySchenectady

Chemical, Inc.,withtheregistered trademarkednameAquanel600,awaterborneinsulating varnish.Thisvarnishisamodifiedalkydsolutioncontaining dimethylaminoethanol andbutylcellosolve.

Thesearchforpertinent datainpublished literature wasconducted intwosteps:(I)asearchofpublished indexesofengineering andtechnical literature, and(2)asearchofcomputerized databases.

Asitturnedout,a 3reportonasignificant surveywaslocatedwhichcontained anextensive bibliography.

Copieswereobtainedofpertinent reportsandjournalarticlesfromthisbibliography.

Themostrecentinformation obtainedwasdated1979.Thecomputerized databasesearchwasthenconducted toobtainthemostrecentinformation available, 1986.Abstracts contained inthecomputersearchoff-lineoutputconfirmed theconclusions whichhadbeenmadefromthepre-1980information.

Copiesofseveraloriginalreportslocatedbythecomputersearchwereorderedtoobtaininformation onthespecificmaterials usedonthemotorinquestion.

Noinformation wasfoundonthespecificmaterials usedontheD.C.CookSafetyInjection Motor.However,alltheinformation obtainedfromworld-wide sourcesconfirmsthatwithfewspecificexceptions organicmaterials usedforpaints,varnishes, andinsulating coatingsmaybeexpectedtoperformsatisfactorily toradiation dosesupto108rads.Thisinforma-tionissummarized inthelastsectionofthisreportandpertinent detailshavebeenhighlighted byarrowsinthelefthandmargin(==>).CONCLUSIONS Reviewoftheinformation obtainedthroughtheliterature searchsupportsthefollowing conclusions:

(1)Radiation damageisnotlikelytooccuruntilthevarnishes andpaintsinquestionhavereceivedadoseofmorethan108rads.(2)Thereisnotlikelytobeanyproblemunlesstheoriginalandover-laid varnishandpaintsarechemically incompatible.

(3)Itisfeasibletoperformarelatively simplelaboratory evaluation ofthematerials inquestiontodetermine chemicalcompatibility.

(4)Ifthematerials areincompatible, thereisnoneedtoperformirradiation tests.

(5)Thermalagingofvarnishandpaintsamplesmaybeperformed priortoirradiation ofsamples.(6)Ifthematerials arechemically compatible, andifelectrical measurements afterirradiation to108rads(gamma)shownodegradation, continued useofthemotorforitsClass1Eapplication isacceptable.

RECOMMENOATIONS Thefollowing recommendations aremadeonthebasisoftheaboveconclusions.

(1)Thechemicalcompatibility oftheoriginalmotorinsulation materials withthenewlyappliedinsulation materials bedetermined experimentally.

Theseexperiments maybeconducted usingtwistedpairsofcopperwireandneednotusestatorwindings.

Smallsamplesizeanalysistechnique shouldbeusedwithasamplesizeof16.(2)Iftheoriginalandthenewlyaddedmaterials arechemically compatible, irradiation experi-mentsshouldbeconducted toverifytheeffectsofradiation onthismaterialcombination.

Theseexperiments shouldbeconducted toatotaldoseof108radswithinsulation resis-tanceandvoltagebreakdown measurements madebeforeandafterirradiation.

Itisnotnecessary tomakethesemeasurements duringirradiation.

/TSReceiving/Visual Inspection Thetestspecimenshallbesubjected toaninspection forthepurposeofidentification anddocumentation.

Theinspection shallbeperformed asspecified inParagraph 3.1,SectionII,ofthisreport.1.2Radiation ExposureThetestspecimenshallbesubjected totheRadiation ExposureTestasspecified inParagraph 3.2,SectionII,ofthisreport.Before,during,andaftertheirradiation period,thetestspecimenshallbesubjected toInsulation Resistance Testsasspecified inParagraph 3.2.1,SectionII,ofthisreport.1.3Post-Test Inspection Uponcompletion oftheradiation

exposure, thetestspecimenshallbesubjected toapost-test inspection.

Theinspection shallbeperformed asspecified inParagraph 3.3,SectionII,ofthisreport.20PROCEDURES 2.1Receiving/Visual Inspection Avisualinspection ofthetestspecimenwasconducted uponreceiptattheradiation facility.

Theinspection wasperformed inordertodocumentthemanufacturer andmodelnumberofthespecimentobetestedandanynoticeable damage.Radiation ExposureThetestspecimenwasplacedinthehotcellatIsomedix, Inc.Facilityandsubjected toadoserateofapproximately 0.5SX10rads/hour.

Atapointmidwaythroughtheradiation

exposure, thetestspecimenwasrotated180'oensureuniformexposuredistribution.

Thetestspecimenwassubjected toaminimumtotalintegrated doseof10.01X10radsgamma,airequivalent.

Uponcompletion ofirradiation, thetestspecimenwasremovedfromthehotcell.Insulation resistance measurements wereperformed onthetestspecimenbefore,during,andaftertheperiodofradiation exposure.

Thetestspecimenwaspositioned inthehotcellduringallinsulation resistance measurements.

Eachinsulation resistance measurement wasconducted byapplying1000VDCtothespecimenmotorphases(connected together) foroneminute.Insulation resistance valueswererecordeduponcompletion oftheoneminuteinterval.
