TheLERnotedthatthePointBeachfacilitywasoperatingat100%capacitywhentheconcernwasidentifiedandthatdesignchangewouldnot'emadeuntilthenextscheduledoutage.UponreceiptoftheWestinghousenotificationonOctober20,1989,RG&E(corporate)initiatedatimelyreviewforapplicabilitytoGinnaStation.BasedontheWisconsinElectricLERandonWestinghouse'scalculationofthelowprobabilityofswitchfailure,itwasapparentthatthematterdidnotconstituteanimmediatesafetyconcern.WhenitwasidentifiedthattheswitchconfigurationwasapplicabletoGinnaStation,aninternalengineeringrecommendationwasmadeconsistentwiththeguidanceoftheWestinghouseletterandattachedLER,thatanEWRbeinitiated.ThiswascompletedonNovember17,1989.ThisrecommendationwasthenevaluatedwithinNuclearSafetyandLicensing,resultinginadiscussionwithsitetechnicalsupportpersonnelrelativetothissituationonDecember19,1989.OnDecember20,sitepersonnelinitiatedaGinnaStationEventReportperProcedureA-25.1(EventNo.89-168).TheeventreportindicatedthatthesitePlantOperationsReviewCommittee(PORC)had,onDecember20,1989,concludedthatplantoperationcouldcontinueforthefollowingreasons:1.Westinghousestatedthatthe.probabilityoffailurewasverylow(i.e.,10'o10'/yr);2.EmergencyOperatingProceduresdirectedOperatorstousemanualSIinitiationwhereindicatorsshowautomaticinitiationhasfailed;3.AseparateautomaticSIinitiatingmechanismwouldactivatewhencontainmentpressurereached4psig;4.Duringdepressurization,abistablelightwill'lertoperatorsofablockedSIsignal;and5.VisualverificationoftheSIswitchplungerpositionindicatesthatthecontactsareintheproperposition.TheviolationstatesthatthetimebetweenOctober20,1989,whenRG&E(corporate)wasnotifiedbyWestinghouse,andthecommunicationofthisinformationtothesitetechnicalstaffonDecember19,1989,showsthattheSIdesigndeficiencywasnotpromptlyidentifiedandcorrected,andindicatesproblemsincommunicationbetweencorporateengineeringandsitepersonnel.WhileRG&Edoesnotdenythisviolation,webelievethattheactionstakenbyRG&EwereappropriateinviewofRG&E'spreliminaryconclusionthattheissuedidnotconstituteanimmediatesafetyconcern.

RG&EbelievesthatAppendixB,CriterionXVIdoesnotestablishaprecisetimelimitforresolutionofsafetyissues.Rather,issuessuchas"promptness"or"timeliness"aresubjectivemattersthatinherentlydependuponthesafetysignificanceofthesituation.GiventhatRGGEhadadocumentedrecommendationfromWestinghousethatnoimmediatesafetyconcernexisted(ascorroboratedbythePointBeachLER),itsactionstowardresolutionoftheissuewerepromptandtimely.AnyotherinterpretationsofCriterionXVIwouldbecountertopublichealthandsafetybecauseitwouldrequirelicenseestotreatalldeficienciesornon-conformingitemsthesame(i.e.,regardlessofsafetysignificance).Thissamebasicphilosophywasaffirmedinananalogouscontext'inrecentguidanceissuedbyNRC'sOfficeofNuclearReactorRegulation'(NRR).Specifically,onJuly19,1989,Dr.T.E.Murley,Director,NRC/NRR,sentamemorandumtoalloftheregionaladministratorsentitled"GuidanceonActionToBeTakenFollowingDiscoveryofPotentiallyNonconformingEquipment."Inhismemorandum,Dr.Murleystatedthat"[t]hereisnogenerallyappropriatetimeframeinwhichoperabilitydeterminationsshouldbemade."Forequipmentwhichis"clearlyinoperable,"animmediatedeclarationofinoperabilityshouldbemadeandtheappropriatetechnicalspecificationsfollowed.However,Dr.Murley'smemorandumcontraststhissituationwiththosewhereequipmentnonconformancessimplyraisetheissueofoperability.InsuchsituationsDr.Murleystatesthat:operabilitydeterminationsshouldbemadebylicenseesassoonasracticable,andinatimeframecommensuratewiththealicableeuiment'simortancetosafetusinthebestinformationavailable,(e.g.,analyses,atestorpartialtest,experiencewithoperatingevents,engineeringjudgementoracombinationofthefactors)(emphasissupplied).Althoughthisguidancerelatestotimingofoperabilitydeterminations,itisequallyappropriatewithrespecttoresolutionofopenitemsunderCriterionXVI.Consistentwiththisphilosophyandbasedonthebestinformationavailable,futurecasesofthistypewillberesolved"assoonaspracticable"andinatimecommensuratewiththesafetysignificanceofthematter.CommunicationbetweencorporateandsitepersonnelwillbeinitiatedpromptlyonceapplicabilitytoGinnaStationisdetermined.CorrectiveStesWhichHaveBeenTakenandtheResultsAchievedCorporateandsitetechnicalstaffandthePORChavereviewedthecircumstancessurroundingthepotentiallygenericdesigndeficiencyrelatedtothecontrolroomSIblock/unblockswitch.AsstatedinLER89-016,the.followingactionsweretaken:
