Forexample,PhaseIconsisted of60documents containing 365items.Basedon13of60documents beingdeficient tosomedegree,thepercentunsatisfactory was22percent.Basedon38itemsof365beingdeficient thepercentunsatisfactory is10.1percent.Whentheinformation wasfurnished totheNRCinameetingNovemberIO,1980andintheinterimreports,thepercentunsatisfactory wasfurnished onthislatterbasis.Throughout theassessment, theteammaderecommendations intendedtoenhancetheeffectiveness ofcorrective actiononfutureoccurrences ofsimilarconditions.
Inallcaseswhererecommendations weremade,thecommitted corrective actionhadbeenimplemented andwassatisfactory forthespecificdeficiency identified.
Insomeinstances, reviewers ofVolumeIhadtheperception thatthecategorization "Satisfactory withRecommendations" equatedinsomemannerto"Unsatisfactory".
Thisperception isincorrect.

10023h0'XECUTIVE SUMMARYTheNuclearRegulatory Commission (NRC)directedNiagaraMohawkPowerCorporation (NMPC)tohaveanindependent assessment ofcorrective actionimplementation andade-quacyperformed.
Management AnalysisCompany(MAC)wascommissioned byNMPCtoperformthisindependent assessment ofcorrective andpreventive actionsrelatedtodeficiencies identified bytheConstruction Appraisal Team(CAT)report,themostrecentSystematic Assessment ofLicenseePerformance (SALP)report,NMPCanditsfivemajorsitecontractors duringtheperiod3anuary1,1981toMarch31,1980.Theindependent assessment wasdividedintofourphases.Interimreportswereissuedforthefirstthreephases.Thisreportincludesthefinalresultsofthefirstthreephasesandtheresultsofthefourthphase.Manyoftherecommendations madeintheinterimreportshavesincebeenimplemented byNMPC.Thisreportdoesnotassesstheeffectiveness ofsuchimplementation orofchangesinorganization,
- staffing, andprogrammadesinceMarch31,1980.Theresultsoftheassessment showthat96.1percentoftheitemsforwhichcorrective actioncommitments madebyNMPCanditscontractors overthisperiodwereadequately implemented.
In9.7percentofthesecases,theMACIndependent Assessment Team(Assessment Team)maderecommendations toenhancetheeffectiveness ofcorrective action.In3.9percentofthecases,thecommitted corrective actionwaseithernotimplemented ornotimplemented adequately.
ThePhaseIInterimReportcovered38of60NRC-identified CATitems,forwhichtheAssessment Teamissued6Corrective ActionRequests(CARs).Sixty-six CATitemswereoriginated, but6wereeithernon-safety-related orcombinedwithotherCATitemsreducingtheevaluated numberto60.Theremaining 22itemshavesincebeenassessed, andresultedintheissuanceof6additional CARs.ThePhaseIIInterimReportcovered33of36NRCviolations identified intheNRCSALPreport,and15of61Construction Deficiency Reports(CDRs).OneCARwasissued,38NRCSALPitemswereoriginated, but2wereforthedeficiencies alreadyaddressed inCATitems,thusreducingthenumberto36.TwoSALPitemsandthreeCDRitemshave 10023h0sincebeenevaluated bytheAssessment Team.Noadditional CARswereissued.ThreeSALPitemsand06CDRitemsarestillunresolved andrequireclosurebyNMPC,socorrective actioncouldnotbeconfirmed.
ThePhaseIIIInterimReportcovered169of196NMPCauditfindings, forwhichfourCARswereissued.TwohundredsixteenNMPCAuditItemswereoriginated, but19wereeithernon-safety-related, coveredinanotherphaseorwereNineMile1items.Oftheremaining 27items,7remainopenandrequireNMPCclosure,and20areevaluated here.Noadditional CARswereoriginated.
TherewasnointerimreportforPhaseIV.Itcovered2,600deficiency documents forthefivemajorsitecontractors.
Theevaluation showed2,550corrective actioncommitments tohavebeensatisfactorily resolved.
OnehundredfiftyofthesewerejudgedSatisfactory withadditional actionrecommended toenhancecorrective actioneffectiveness.
In90cases,thecorrective actionhadnotbeenimplemented adequately andCARswereorigi-nated.Whiletheoverallresultsoftheassessment showedacceptability in96.3percentofthecases,indicating ahighdegreeofreliability inimplementing committed corrective actions,somedeficiencies wereidentified bytheAssessment Team.Acceptable corrective actionhasbeencategorized as"Satisfactory" and"Satisfactory withRecommendations".
Inbothcases,thecorrective actionwasimplemented andwaseffective forthespecificdeficiency.
Analysisshowedthattheprimaryareasofdeficiency relatedto8ofthe18Criteriaof10CFR50,AppendixB,and5concernsrelatedtohardwaredeficiencies.
Theseareasarediscussed furtherinthefollowing paragraphs.

SCOPEAspartofitsordermodifying theconstruction permitfortheNineMilePointUnit2(NMP-2)nuclearstation,theNuclearRegulatory Commission (NRC)directedNiagaraMohawkPowerCorporation (NMPC)tohaveanindependent assessment ofcorrective andpreventive actionsperformed.
Thisassessment wastoaddressdeficiencies identified byrecentNRCinspections andbyNMPCanditssitecontractors betweenJanuary1,1981,whenconstruction wasresumed,andMarch31,1980,whenarestructured qualityassurance (QA)organization wasinplace.Actualrestructuring beganinJanuary1980.TheNRCspecifically directedNMPCtoaddressthecorrective actioncommit-mentsmadeinresponsetotheConstruction Appraisal Team(CAT)reportofJanuary31,1980,themostrecentSystematic Assessment ofLicenseePerformance (SALP)report,deficiencies identified byNMPCasaresultofitsownsurveillance andauditactivities, anddeficiencies identified bythemajorsitecontractors:
StoneandWebsterEngineering Corporation (SWEC),ITTGrinnellIndustrial Piping,Incorporated (ITT),ReactorControls, Incorporated (RCI),GeneralElectric(GE),andJohnsonControls, Incorporated (JCI).Management AnalysisCompany(MAC)wascommissioned byNMPCtoperformanindependent reviewofcorrective actioncommitments andimplementations forprogramdeficiencies andnonconformances fortheperiodJanuary1,1981throughMarch31,1980.Thepurposeofthisreviewwastodetermine whethertheunderlying orfundamental causesforthedeficiencies hadbeencorrectly identified, andwhethercorrective andpreventive actionshaveadequately addressed theunderlying andfundamental causesandresolvedthedeficiencies.
12PROJECTAPPROACHAnalysisofthetaskdefinedbytheNRCmadeitevidentthattheworkcouldbedividedintofourphases:thefirsttwodirectedto.NRCfindingsandconcerns, thethirdtoNMPCsurveillance andaudits,andthefourthtodeficiencies identified bythemajorsitecontiactors.
Muchoftheworkofthevariousphaseswasactuallyperformed inparallel.
MACassembled a
10023h0teamofhighlyqualified personnel toperformtheassessment fromitsownstaffandfromotherconsulting andengineering organizations.
ThisIndependent Assessment Team(Assessment Team)wasmadeupofindividuals withnopreviousinvolvement atNMP-2.Eachteammemberhadtechnical expertise inoneormoreofthefollowing disciplines:
~Civil/Structural
~Electrical/Instrumentation andControls(IRC)~Welding/Nondestructive Examination (NDE)~Mechanical
~MaterialandReceiving
~SoftwareAsmanyas05professionals wereusedoveranapproximate 6-monthperiod,withanaverageof36personsthroughout theassessment.
TheAssessment Teamaveraged13yearsofnuclearexperience andhadatotalof1,007yearsofaccumulated professional experience.
Teammembersreviewedatotalof2,900documents andrelatedcorrective actioncommitments.
Ofthetotal,1,920documents relatedtocorrected physicalcomponents, systemsorstructures, whichwereassessedforconformance tospecified requirements aswellasforcorrection oftheidentified deficiencies.
Deficiencies weresegregated bydiscipline (e.g.,mechanical, electrical, civil/structural) andassignedthroughdiscipline leaderstoindividual teammembersforevaluation.
TheAssessment Teamevaluated thecorrective andpreventive actionsthatNMPCoritsappropriate contractor considered adequatetoresolvethedeficiency.
Deficiencies identified bytheNRCCATinspection, SALPassessment andbyNMPCauditandsurveillance activities were100percentevaluated.
Becauseoftherelatively largenumberofdeficiencies identified bythesitecontractors overtheperiodinquestion, astatistical samplingplanwasusedtoidentifythedeficiencies tobeevaluated.
Thedeficiencies wereidentified asprogram-maticorhardware-related andfurtherseparated bydiscipline.
10023hO1-3Thedeficiencies ineachspecificdiscipline identified byeachspecificcontractor constituted alot.Eachlotwassampledatnormalsamplinglevelsinaccordance withMIL-STD-105D, TablesI,IIAandVIIA,(withthemodifi-cationthatpopulations under100were100percentinspected) toachievea95percentconfidence levelthat95percentofthelotwasofadequatequality.Ifthesampleconfirmed thattherequiredlevelofqualityhadbeenmaintained, thelotwasconsidered acceptable andnofurtherreinspection wasrequired.
Ifthesampledisclosed thattherequiredlevelofqualityhadnot'eenmaintained, thesamplesizewasincreased totightened sampling.
Iftightened alsoshowedthatthedesiredqualitylevelhadnotbeenobtained, theAssessment Teammaderecommendations forimprovement whicharecontained inthisreport.TheAssessment Team'seffortconsisted ofathoroughreviewofthestatedcorrective andpreventive actionandstatedorimpliedrootcause;interviews withresponsible personnel; reviewofdesign,appropriate processes, acceptance criteriaandmethods;evaluation ofrelatedprocedures andotherdocumentation; andevaluation ofpersonnel skillrequirements andqualifications.
TheAssessment Teamperformed.
sufficient reinspection ofaffectedhardwaretodetermine whetherthecorrective actionhadbeenimplemented asstated,andwhetherithadbeenappropriately appliedonagenericbasissuchaswouldprecluderecurrence ofalikeproblemondifferent itemsofhardwareordocumentation.
Reinspection coincided withareviewofQAdocuments providing acceptance
- criteria, e.g.,procedures, designdrawings, specifications, checklists, inspection instructions usedinperforming theoriginalqualityassessment, andthosedocuments pertaining tocorrective andpreventive measuresafterthedeficiency wasidentified.
Requiredphysicalinspections wereperformed bypersonnel qualified intheappropriate discipline.
Corrective actionrelatingtoanydeficiency wasevaluated as"Satisfactory",
"Satisfactory withRecommendation",
or"Unsatisfactory".
A"Satisfactory" ratingindicated thatthefundamental causeofthedeficiency hadbeencorrectly identified andthatthecorrective andpreventive actionhad 10023h4adequately addressed thecauseandresolvedthedeficiency.
Aratingof"Satisfactory withRecommendation" indicated thattheaction.hadadequately addressed thespecificdeficiency, buttheAssessment Teamfeltfurtheractionwouldassistinprecluding recurrence oftheproblem.Corrective actionsratedas"Unsatisfactory" werethoseforwhichthecommitted corrective andpreventive measureshadnotbeenimplemented,'r wasineffective inresolving thedeficiency.
Itemsrated"Unsatisfactory" wereidentified onanNMPCCorrective ActionRequest(CAR)bytheAssessment TeamandissuedtoNMPCfordisposition.
ThoseCARsoriginated bytheAssessment TeamwhichwereclosedbyNMPCwerealsoreviewedforadequacyofcorrective action.OVERVIEWTheAssessment Teamevaluated 2,900deficiency documents, totaling3,390items,anddetermined byreviewofdocuments andbyphysicalinspection ofaccessible hardwareitemswhethercorrective andpreventive actionhadbeentakenwhichproperlyaddressed thestateddeficiency andwasappropriately andeffectively appliedtoprecluderecurrence.

GeneralNRCconcernsstatedintheCATandSALPreportsaread-dressed,aswellasspecificdeficiencies forwhichtheteamfoundtheimple-mentation ofcorrective andpreventive actionstobelessthansatisfactory.
2.1NRCORDERITEMSTheNRC,initsCATandSALPreportsandOrder,identified significant pro-grammatic problemswithNMPC'sQAprogram,specifically insiteauditingprograms, thecorrective actionsystem,Procurement QualityAssurance (PQA),documentcontrol,designchangecontrolandtimeliness ofinspection andcor-rectionactivities.
TheNRC'sOrderalsoidentified areasofconcerninvolving
- hardware, specifically radiographic film,concreteexpansion anchors,andcableinstallation inthePowerGeneration ControlComplex(PGCC).Theseareaswerespecifically addressed inNMPC'sresponseto.theOrderdatedMay10,1980.Theyareaddressed inthisreporttotheextentthattheAssessment Team'sevaluation substantiated orresolvedthem.2.1.1litAssurance ProamITheNRCSALPreportcitedaweaknesswithintheNMPC/SWEC/ITT QApro-gram.TheAssessment Teamreviewedandevaluated theQAprogramsofsitecontractors bymeansofinterviews andprogram/procedure overview.
TheNMPCsiteQAprogramhasbeenstrengthened.
QualityAssurance Proce-dure(QAP)19,00,"QualityAssurance Department atNineMilePointPP2",wasissuedMarch22,1980,todescribethesiteorganization anddefineresponsibil-ities.Thesiteorganization chartdescribes theresponsibilities ofeachofthefourunitswhichmakeupthesiteorganization.
Additional emphasishasbeenplacedontheauditandsurveillance programs.
SWECqualityprogramshavebeenupgraded, partlyinresponsetotheCATandSALPfindingsandpartlyasacontinuation ofongoingqualityimprovement programs.
Additional emphasishasbeenplacedonauditingandsurveillance ofconstruction activities.
Specialtaskgroupshavebeenestablished toinvestigate 2-210023h4problemareas.TheQualityControl(QC)staffhasbeenincreased byapproxi-mately20percent.Procedures havebeenrevisedtoprovidebettercontrolofqualityactivities.
ITThasincreased thesitequalitystafftoprovidebettercoverageofconstruc-tionactivities.
TheDirectorofQualityAssurance/Quality Control(QA/QC)wasassignedtheresponsibility fordeveloping trendreportstoidentifyproblemareasandprovideameasureofprogress.
Workisunderwaytoutilizeacompu-terizedsystemforpreparing trendreports.Thequalitydocumentation efforthasbeenupgradedandreorganized.
ItnowisdirectedbyaManagerwhoreportsdirectlytotheDirector, QA/QC.Approvalhasbeenrequested foradditional QAEngineers.
Procedures governing projectactivities havebeenreviewedand,whereindi-cated,upgradedtodirectmoreattention toqualityandtoassurethecompleted facilitywillconformtoestablished requirements.
Themeasuresnotedaboveshouldimprovequalityperformance intheareasofconcernnotedintheSALPreport.Someproblemareaspersist,andadditional improvements canbeexpectedasthelongerrangeprogramimprovements becomeeffective.Forexample,theresultsoftheindependent assessment confirmthatqualityprogramweaknesses existedintheareasidentified bytheNRC.Whileimple-mentation oftheactionsnotedabovewereconfirmed bytheAssessment Team,itistooearlytomeasuretheeffectiveness ofsuchchanges.Inaddition, theAssessment Teammadespecificrecommendations that,togetherwithcontinued emphasisonsurveillance andaudits,shouldenhanceprogrameffectiveness.
2.1.2SiteAuditinProramTheCATreportstatedthattheSWECauditingprogramwasnotsufficient anddidnoteffectively identifyandresolvemajorconstruction problems.
TheAssessment Team'sreviewoftheSWECauditingprogramprocedures revealedgeneraldirectives forcompliance withANSIN05.2.12andspecificinstructions regarding auditformatandformsutilization.
Theprocedures appearade-quateandshouldresultinaneffective auditsystem,ifproperlyimplemented.
10023hO'-3 ActionstakentoimprovetheSWECauditprogramincludedinitiation ofaprojectprocedure whichaddresses timelyclose-out ofauditobservations; increased auditfrequency perthe1980auditschedule; andsupplementing theauditstaffwithtechnical specialists fromoutsidethequalityorganization.
Thepreventive actionplannedisappropriate.
TheAssessment Team,initsreviewofSWEC'sAuditFindings, notedaconsid-erablelackofobjective evidencethattheactionstakentoresolvethefindingswerecompleted.
ExamplesincludePre-survey ASMEIIIAudit1983,C-0andSiteAudit20,1981.Additional SWECreporteddeficiencies, Nonconformance andDisposition Reports(NRDs),andInspection Reports(IRs),havealsobeenclosedwithoutsufficient evidencethatcorrective actionwasverified.Therewasnoenforcedtimelimitforreplyorconclusion.
FieldQualityControl(FQC)inspectors didnotidentifynonconformances adequately whichresultedinexcessive timespentresearching problemresolutions.
Significant deficiencies intheNMPCauditprogramwereaddressed intheCATreport.TheAssessment TeamverifiedthattheNMPCapproachtositeauditshassincebeenevaluated andpositiveactionhasbeentakentoemphasize hard-wareinsubsequent audits.Thisactionhasbeeninitiated throughdevelopment andimplementation ofnewQAprocedures.
The150"openaudititems"identi-fiedbytheNRChavesincebeenclosedandreportedthroughthenewNMPCcomputerized trackingandtrendingsystem,andNMPChasdiscontinued theuseof"openaudititems".AnumberofNMPC'saudititemswereclosedwithoutverification thatrequiredactionswereaccomplished anddocumented.
EightNMPCaudititemsfailedtoidentifyobjective evidencetosupportauditclosure.ManyNMPCaudititemsfailedtoidentifyadequatecorrective actionandactionstopreventrecurrence ofauditdeficiencies.
TheNRCalsoexpressed aconcernthatinthecaseofNMPCandITTsomeauditobservations shouldhavebeenwrittenasnonconformances, andthatthereisnotamechanism inplacetoreviewauditobservations forsignificance andrep'orta-bility.NMPCrevisedtheirprogramtoincludeprovisions forreviewing auditdeficiencies forsignificance.
Thisconcernwasaddressed inCATItem 2-010023h403D-83.TheAssessment Team'sreviewrevealedthatthelicensing procedures associated withreporting andcorrection ofdeficiencies under10CFR50.55(e) andlOCFR,Part21,havenowbeenimplemented.
ITTissuedaletterindicating thattheManagement AuditReportwouldincludeastatement thatthe10CFR50.55(e) reviewhasbeenaccomplished.
InthecaseofITT,theAssess-mentTeamrecommends thattimelyreviewforreportability andcommitments foractionstopreventrecurrence beaddressed byITTinprocedures toassurecontinued compliance.
Auditortrainingonreportable deficiencies shouldbereevaluated, andanyitemslackingobjective evidenceoflOCFR50.55(e) reviewshouldberereviewed anddocumented.
Responsetimehasbeeninordinately longforvendorandcontractor AuditFindingswhichresultedinAuditReportsnotbeingclosedinatimelymanner.Inoneinstance, thisresultedininadvertent useofanunapproved supplier.
Additionally, NMPChasacceptedcontractors'esponses toauditfindingswith-outalwayshavingmadeacomprehensive reviewofsupporting documentation.
TheAssessment Teamidentified atleasttenNMPCaudititemsthatwerenotclosedinatimelymannerinaccordance withprocedural requirements.
ForSWEC'sNRDs,therewereseveralinstances ofdelaysofupto70daysfromthetimethenonconformances werefirstdiscovered untilthenonconformance documentwasprepared.
SomeexamplesareSWEC'sNRDs5332,5026,5145,6903,and0801.Anexcessive amountofdelaywasalsonotedintherevisingofConstruction Management Procedures (CMPs).Inassessing SWECSiteAudit23,oneCMPrevisionrequiredsevenmonths,anothertenmonths.Theprogramshouldbereviewedforefficiency andtimeliness.
2.1.3Corrective ActionSstemTheNRCstatedinitsCATreportthat"corrective actionsystemswerede-ficientwithregardtothecorrection ofnonconformances identified andtheassociated documentation".
TheNRC'sconcernsregarding theadequacyofNMPC'sverification ofcorrective actionfocusedondocumentation, timeliness, andtheeffectiveness ofsurveillance andverification activities.
I0023hO'-5 Documentation SomeEngineering andDesignCoordination Reports(ERDCRs)wereusedtodocumentnonconforming conditions, asnotedinCATItem9-83.TheAssess-mentTeamfoundbyreviewoftrainingrecordsthattrainingofsiteofficepersonnel, CherryHillPQApersonnel andselectedkeypersonnel intheproperuseofthesehasbeenaccomplished.
Engineering changesof,acceptance criteriaarenowresolvedforCATitemdeficiencies, butFQCverifications havenotbeenperformed toensurethatpreviously installed itemswouldmeettherevisedcriteria.
FQCverification ofpreviously installed itemsisplannedbutnotasyetimplemented.
SWECissuedProjectProcedure (PP)20,Supplement Number820-67onMarch30,l980toprovideadditional construction guidancerelativetosituations inwhichadesignchangeisissuedafteraninstallation hasbeencompleted andinspected.
TheAssessment Teamrecommends thatallpre-viouslyissueddesigndocuments, HcDCRsandEngineering ChangeNotices(ECNs),thatidentified nonconforming conditions bereviewedforpotential reportability underlOCFR50.55(e) andlOCFR,Part21.TheSALPreportalsonotedproblemsinthedocumentation ofcorrective action.TheNRCnotedthatthedocumentation packetshouldcontainacopyoftheinitialsurveyreportwiththeassignedconcernnumber;actionthatwasinitiated tocorrect;lOCFR50.55(e) interimreport,ifapplicable; verifiedcor-rectiveactiontaken;finallOCFR50.55(e) report,ifapplicable, togetherwiththeNRCfinalIRwiththelineitemnoticeofclosure;andthatsuchdocumenta-tionshouldbemandatory.
TheAssessment Teamdetermined thatalldocumen-tationpackagesprocessed oflatehavebeenverycomplete, andtheappropriate degreeofdocumentation isnowrequired.
Therefore, thisisnolongerconsid-eredaconcern.TheNRCalsoexpressed concernthattheuseofType"C"IRsprecludetrending, andallowtraining, meetingsandmemostobeusedtocorrect'thedeficiency ratherthanpreparing anNhD.TheAssessment Teamsubstantiated theiVRCconcern,andrecommends thatType"C"IRsbeutilizedasaprogrammatic surveillance documentonly.Anycorrective actionforhardwaredeficiencies requiredbyaType"C"IRshouldbedispositioned usingaNRD.Itisrecom-mendedthatfurtherfollow-up onthisconcernbeinitiated byNMPC.CAR 2-610023hO80.0166wasissuedby'heAssessment TeamonthetimelyclosureofSWEC'sType"C~!ftRsSWECType"A"IRsdonotnormallyindicatetheactiontakenand/orthejustifi-cationtoclosethedeficiency.
Thisresultsinlittlesupporting documentation toverifywhatactionsweretakentoresolvetheproblem.Thisdeficiency contributed toCAR80.0116regarding reworkedanchorbolts.Timeliness Excessive contractor delaysinimplementing committed corrective/preventive actionwerenotedintheCATAssessment.
AnexampleofthisisCATItem31-83.TheSALPreportalsonoteddelaysofuptoeightmonthsininitiating, resolving anddispositioning deficiencies.
ExamplesincludeNRCItem81-13-01EandCDR81-02.TheAssessment Teamnotedsomeinadequacies inthetrackingsystemforNRDsrelatedtoexpeditious closureofopenNdcDs.Thepresentsystemforwardsacopyofthedispositioned NODtothecontractor forhisaction.Thereisnomechanism for.trackingwhatthecontractor isdoingtoimplement thedisposi-tionandclosetheNRD.NRD-0952, forexample,hasremainedopenformorethanayearwiththecontractor takingnoactiontomakethenecessary repairs.TheNADlogshouldbemonitored periodically andstatusupdatesprovidedsothatNdcDscanbeclosedoutmoreexpeditiously.

Theengineershouldthenconfirmthesituation sothatacompletedisposition canbeprovidedtoresolvetheentirediscrepancy.
Verification ofCorrective ActionTheNRCnotedthatreinspection activities bycontractors andverifications byNMPC'sQAhavenotbeentotallyeffective.
Examplesofthiscondition werefoundbytheAssessment TeaminCATItem25-83,"RCIUndersized Welds";
10023hO'-7 CATItem01-83,"WeldFillerControl";
andCATItem21-83,"CivesUndersized Welds",whichresultedintheissuanceofCARs80.0003,80.0105and80.0057.2.1.0Procurement alitAssurance TheiVRC'sconcernthatmaterialinspected atthesourcepriortoreleasebySWEC-PQChasoftenbeeninnoncompliance w'ithprocurement documents wasassessedbyCATItem7-83.TheAssessment Teamverifiedthatcorrective actionaddressed thecommitment torevisesourceinspection planningtorequirewitnesstestingandverification ofobjective evidence.
Thepreventive actionplansrequireforNMPCtoparticipate insourceinspection (selectively).
Theactiontaken,inadditiontoimplementation oftherecommendations inSection0.0,shouldresolvethisconcern.TheNRCalsonotedthatalthoughtheinspection planforCivesSteelrequired100percentvisualexamination inaccordance withAWSD.l.l,beamswerefoundwithinsufficient weldmaterial.
Thishasbeenaddressed inCATItem21-83.TheAssessment Teamootedllunsatisfactory weldsthatwereidentified andreportedonNdcDs,butwerethendispositioned "acceptasis".TpeAssessment Teamhasrecommended that.theentirelot(notjustthosethatwereconsidered unsatisfactory) bereinspected anddispositions madebyEngi-neeringtoensurethatbeamswithunsatisfactory weldsarenotbeingusedelsewhere intheproject.2.1.5DocumentandDesinChaneControlDocumentControlThemajorNRCconcernspertaining todocumentcontrolwere:(1)drawingswerenotbeingreviewedaccording toprocedures, and(2)iVMPCandSWECdidnothaveadequatecontroloverthedesignchangesystem.TheAssessment TeamverifiedthatiVMPChasinstituted anumberofchangesinitsdocumentcontrolsystem.Ithasestablished acomputerized systemforpostingdesignchangesandreducedthenumberofdrawingstationstoaidinmorepromptdistribution ofchanges.Inaddition, iVMPCestablished ataskforcetoreviewtheproblemandareviewprocessfornewdrawings.
TheAssessment Teamrecommends thatallNMPCpermanent plantrecordsbe 2-810023hOindexed,protected, consolidated andretrievable inaccordance withANSIN05.2.9.Atpresent,recordsaredifficult toaccess,astheyarekeptinseveraldifferent locations andindexingforretrievability isnotuniform.Despiteimprovements andcontinued attention byNMPCandSWEC,documentcontrolcontinues topresentproblems.
Improvements havebeenandarebeingmadebutproblemareasstillpersist.Relateddocuments donotcross-reference eachotherforeaseoftracking.
TheITTprogram(s) foridentifying, voiding,superseding, invalidating andclosingdeficiency documents shouldbereevalu-ated.Inonecase,fourdifferent DRs,oneNRDandoneIRweregenerated toidentifyandprocessthesameproblemwhich,inthefinalanalysis, wasnotanonconformance.
Averification ofdeficiency shouldbeinitiated oneachnonconforming condition identified inordertopreventthistypeofsituation.
Thebasisforclosureofvoidedorsuperseded nonconformance documents shouldalsobelistedonapplicable forms.Frequently insufficient orincorrect reference information anddisposition directions areprovidedoncorrective actiondocuments, Forexample,ITTNRP-077wassubmitted toSWECfordisposition; however,SWECreturnedsametoITTunanswered becauseofinsufficient information.
SWECrequested ITTtoreevaluate andprovidesupporting dataandresubmit.
Thisactionneveroccurred, andtheNRDwassubsequently closedbyoriginating otherNRDs.Thereappearstobeaprogrammatic deficiency inITT'sNODprogram.InthespecificcaseofITT'sNRDIG-1750,theNRDwassubsequently revisedfromCATIItoCATIwhentheclose-out signature wasappliedwithoutobtaining newsignatures fromthosewhopreviously approvedthedisposition.
Theprocedures shouldberevisedtocorrectthisproblem.ITTprocedure FQCIO.I-O,Revision15,doesnotrequiretheNODformtobefullycompleted whenanewYidcDisissuedunlesstheNODhasbeenprocessed byDocumentControl.Thisdeficiency allowsNRDstobesuperseded orrevisedbysubsequent NRDswithoutproviding apapertrailtofollowtheproblem.Theprocedure shouldbeamended.
100231K'-9 DesignChangeControlTheNRC'sCATreportidentified problemsinthedocumentchangecontrolprogramindicating that"craftsandinspectors maynotbeusingthelatestdesigndocuments intheperformance oftheirwork".Italsocitedthe"highrateofdesignchangeinitiation andtheinability tomaintainandreviseconstruction drawingsinatimelymannertoreflectsuchchanges".
DuringtheAssessment Team'sreviewofdrawings, itwasnotedthatrecentchangestosomedrawingsusegenericandnon-specific terminology inthedrawingrevisionblock.Anexampleis"(F-8,G-8)asperlatestdesigndocu-ments".Severalexamplesofthiswerenoted.Thispracticemakesitvirtually impossible toidentifywhetherallappropriate changeshavebeenincorporated.
SWECshouldberequiredtobemoreexplicitinidentification ofchangestodrawings.
TheNRC'sconcernthatQCinspection hadnotbeengiveninspection attributes toassurethatequipment (batteryrack)installations areconsistent withseismicqualification requirements wasaddressed inCATItem2-83.Thiswasnotsubstantiated bytheAssessment Team.Theinspector properlyinspected tothedrawing,whichspecified "steel"bolts.Thisspecification isconsistent withseismicqualifications.
TheAssessment TeamconcurswithNMPC'sconclusion.
TheNRC'sconcernthatinadequate procedural controlexistsfortrackingallaspectsofequipment andtheirdesignchangeswithseismicqualification requirements wasaddressed inCATItem2-83.NMPC'sactionsweretoidentifyandreviewexistingassemblies andconnections forconsistency withseismicqualifications, andtoestablish trackingcontrolsfordesignchangeswithseismicqualification requirements inSWEC'sPP90.TheAssessment Teamverifiedthattheseactionswereappropriate andthattheyhadbeenimplemented.
2.1.6RadioahicFilmaliInitsCATreport,theNRCfoundiVMPC'sprogramforreviewandacceptance ofradiographs wasdeficient.
TheAssessment Teamsubstantiated thiscon-cern.Itfoundthattheoverallqualityoftheradiographic filmanditshandlingwaspoor.Originalfilmwasnotavailable forthoseweldments thatwere L0023h0repaired, makingitimpossible todetermine whatareawasactuallyrepaired, oriffullcoverageoftherepairareawasobtained:
Inthemajorityofcases,no"readersheet"fortheoriginalweldwasavailable whenrepairswererequired.
Thecondition ofthefilmwassuchthattherewasconcernwhetherthefilmwouldremainlegibleforthedurationoftherequiredretention.
Finally,therewerediscontinuities onsomeradiographic filrqthatwerenotnotedontheRadiographic Examination (RT)readersheet.TheNRCnotedthatSWECIRsidentifying radiographic problemswerenotbeingdispositioned inatimelymanner,corrective actionappearedinadequate, andSWEChadfailedtocontrolandmonitorthesiteradiographic activities ofITT.TheAssessment Teamreviewedtheproblemandthecorrective actionthathadibeentaken.NMPCconducted a100percentreviewofITT'sradiographs whichhadbeenacceptedandfiledinthevaultasof3anuary1980.Deficiencies discovered byNMPCduringthereviewwerenotedonNMPC'sSurveillance Reports(SRs).AsaresultofNMPCSRs,SWECgenerated severalType"C"IRstotrackNMPC-identified deficiencies andinitiatecorrective.

Theenhancement condition isnolongeraproblem,andtheotherradiographic problemsalsoappeartobeintheprocessofresolution.
Basedontheactiontakentodateandtheactionsinprogress, theAssessment Teambelievesthatradiography performed on-sitewillmeetthequalityrequirements.
\2.1.7ConcreteExsionAnchorsInitsCATreportandintheOrder,theNRCstatedthatconcreteexpansion

TheNRCalsonotedthattherewasnoinspection attribute toassurenutsarenot"bottoming out"onthethreadsoftheconcreteexpansion anchorbolts.TheAssessment Teamverifiedthatrevision0toSpecification S203Cincludedanattribute for'bottoming out".Installation procedures for"drilled-in concretetypeexpansion anchors"havebeenrevisedtoincludethisinspection attribute.
10023h4PowerGeneration ControlComlexTheNRC'sOrderobservedcableseparation violations incablesinPGCCduct-waysandcableswhichenterPGCCcontrolboards.TheAssessment Teamfoundthatconcernsareactivelybeingaddressed byNMPC,SWECandGEbydeveloping andimplementing subdivisional separation instructions formodifying theclasslEdivisionpanelsandtermination cabinetsinvolvedinpreviously acceptedshoporvendorwiring.Thestatusofthisworkaccomplished todatewasstilluncleartotheAssess-mentTeam.ManyFieldDesignInstructions (FDls)andFieldDeviation DesignReports(FDDRs)remaintobeclosedout.Work,rcworkandrepairstillmustbeperformed throughout thePGCCcomplexforthereduction orelimination ofallseparation criteriaconcerns.
ItappearsthatNMPCisnotproceeding forcefully togetGEandSWECtoresolvetheseparation criteriaproblem.Therearenumerouschangedocuments toresolvetheproblemsrelatedtoGEequipment, toauthorize thework,andtoverifythecompletion ofwork.Aconcerted effortmustbemadetoclose-out thedocumentation bycompleting theprescribed work.Specificexamplesofthisconcernarediscussed below.Theunderfloor racewaycovershavenotbeeninstalled forproperseparation.
Attention shouldbegiventoinstalling thecoversassoonaspossibleinthesequenceofevents.Installation ofthecoversatalaterdatemaybeasignifi-cantproblem.Separation attributes arenotalwaysaccurately recordedonIRs,astheAssess-mentTeamverifiedforCATItems3-83and8-83.TheIRsweremarkedas"later"or"NR"whendivisional separation criteriawerenotmet,ratherthanbeingdocumented asnonconformances.

..3~/ProblemsintheWelding/NDE areaidentified bytheNRCinvolved1)thequalityofradiographic film,and2)thequalityofweldsandassociated documentation.
Thefirstconcernwasaddressed aboveinSection2.1.7,Radiographic FilmQuality.Thesecondconcern,addressed inthissection,coversweldquality,weldingrepairs,weldmaterialcontrol,welderqualifications, andweldinspec-tion.TheNRCidentified alargenumberofundersized shopweldsforsupportsbyCivesSteelinCATItem21-83.Basedonvisualinspection, 15to20percentwererejectable.

WeldRepairsTheAssessment Teamfoundanumberofproblemswithweldrepairs,asdis-cussedinthefollowing paragraphs.
Over-grinding isacommonoccurrence whenattempting toremoveminordefects.Craftsshouldbeinstructed nottochase(grind)defectstotheextentthatminimummaterialthickness isvio-lated.DefectswhichcannotberemovedwithaminimumofgrindingshouldbedirectedtoEngineeing fordisposition.
Allcontractors exceedengineering welddesignsizewhenperforming weldrepairs.Duringreinspection thiscondition existedinapproximately 75percentofreworkedwelds.Althoughnodistortion wasobserved, depositing moremetalthanrequiredbydesigniscostlyintimeandmaterial.
Craftsshouldbeinstructed/trained tolimitweldsizetoEngineering requirements.
instruction shouldbeapplicable toinitialweld,repairandrework.ITTconsistently failedtoidentifyweldrepairsaccording toSpecification P30ICwhichstatesthat"eachattemptatrepairofasubjectweldwillbeidentified withanRl,R2,etc.,asrequired".
Onpiperestraint weldrepairs,theinterpretation ofSpecification P30lC,i.e.,replacement ofweldnumbersonmajorrepairsanddetermining whenaweldshouldorshouldnotshowa"deleted" indicator, isinconsistent.
At0 10023hO2-17SWEC'sQAprocedure, QS-9.3,specifies thatWeldDataSheets/Weld RepairDataSheetsarenotrequiredforweldswhichdonotrequireNondestructive Examination (NDE).Thiscondition createddifficulty inverifying theadequateclose-out ofthesetypeIRs.Duetoalackofdocumentation, theAssessment Teamhadnochoicebuttoacceptreworkofweldsbasedonvisualinspection ofcondition (ifaccessible) andinspector's signature.
Thispracticeisalsoper-formedbyothercontractors on-site.TheAssessment Teamdetermined thistobeunsatisfactor yandCAR80.0110wasissued.WeldMaterialControlTheAssessment Teamalsofoundanumberofproblemswithweldmaterialcontrol.3CIweldfillermaterialcontrolprocedures requiretheforemanorweldertoplacetheweldnumberofthejointbeingweldedonthecarboncopyoftheWMR(QualityCategoryIonly).Whenreviewing WMRs,itisdifficult todetermine whereweldingwasactuallyperformed fromthesedocuments.
ThecurrentRevision12ofQualityAssurance Standard9.00hasdeletedtheabovesentencebutdidnotreplacetherequirement; therefore, theweldnumberplacement sectionisnotcoveredclearly.Thesurveillance performed bySWEConcontrolofweldfillermaterialisper-formedonceaweek,butthesurveillance doesnotdistinguish betweenCATIorCATIIwork.Therefore, manyoftheWMRsinspected areforCATIIworkorweldertesting,etc.TheNRC'sconcernsrelativetoweldrodcontrolhavebeenaddressed inCATItemOl-83.Committed corrective actionhasbeenconsid-eredinadequate andCAR80.0105hasbeeninitiated.
Inaddition, minorerrorsarefrequently madewhencompleting WMRs.TheAssessment Teamrecommends aprogrammodification toprovidecleardefinition ofrespon-sibilities forqualityverification, increased QCin-process inspection andmoni-toring,andadditional trainingforcrafts.WelderQualifications TheNRC'sconcernthat,welderqualifications donotmeetAmericanSocietyofMechanical Engineers (ASME)CodeSectionIXineffectattimeofqualification 2-ISI0023h4wasaddressed inCATItem26-83.Thecondition ofsomewelderqualification recordswasobservedbytheAssessment Teamtobeunsatisfactory andCAR80.0002wasgenerated.

Also,problemswiththevisualinspection ofpipingsupportweldsandthedocumentation forsomewelderqualifications wereidentified inactivities involving RCI.TheAssessment TeamfoundthatITThasonmanyoccasions closedDeviation Reports(DRs)priortocompletion ofradiography.
