DearMr.Johnson,

OnJune8,1990,RG&EnotifiedtheNRCunderthecriterion of10CFR550.72, ofacondition outsidethedesignbasisoftheplantassociated withAOV745,thecomponent coolingwaterisolation returnvalvefromtheexcessletdownheatexchanger.

Thisnotification wasmadeasaresultofinformation contained inTable3.6-1oftheGinnaTechnical Specifications andUFSARTable6.2-13,whichindicated thatAOV745shouldreceiveaContainment Isolation Signal(CIS).However,elementary wiringdrawingsdidnotshowthisvalveasreceiving suchasignal.Subsequent tothisnotification, RG&Edetermined thatinformation contained onTechnical Specification Table3.6-1forMOV749AandMOV749B(component coolingwaterisolation valvestothereactorcoolantpumps)wasalsopotentially misleading basedonthefactthatthesevalvesdonotreceiveaCISbutareshownwithamaximumisolation timeof60seconds.Consequently, RG&Ehasreviewedthebackground information available withrespecttoAOV745,MOV749A,andMOV749B.AllthreevalveswerereviewedbytheNRCduringimplementation oftheTMILessonsLearnedrecommendations andtheSystematic Evaluation Program.Penetration 124awasevaluated inthesetwoprogramsassumingthatitwasnonessential, andthatAOV745wasanormallyopenvalvewhichdidnotreceiveaCISbutwasclosedpost-LOCA.

Meanwhile, Penetrations 127(MOV749A)and128(MOV749B)wereconsidered essential penetrations withnormallyopenedvalvesthatalsodidnotreceiveaCISbutremainopenpost-LOCA.

InaNovember19,1979lettertotheNRCdiscussing TMILessonsLearneptopics,RG&EstatedthatPenetration 124awas"nonesbential" whilePenetrations 127and128were"essential".

Inpreviouscorrespondence fromRG&Eonthissubject(datedJune22,1979),atablewasprovidedwhichlistedallvalvesreceiving aCIS;neitherAOV745,MOV749A,norMOV749Bwerelistedonthistable.9007l70340 900709PDRAGOCK05000244pplleap

/ep44I InTable1oftheFinalEvaluation ReportforSEPTopicVI-4,datedApril12,1982,itisindicated thattheNRCassumedthatAOV745wasnormallyopen,butclosedpost-LOCA.

However,thereisnoinformation listedbeneaththe"Actuation" columnforthisvalvewhichwouldindicatehowthevalvewasexpectedtoclose.ThistablealsoshowsMOV749AandMOV749Basnormallyopenvalveswhichremainopenpost-LOCA.

Thesevalvesareshownas"remotemanual"under"Actuation".

Inaddition, drawingsandtheoriginalGinnaFSARasusedbytheNRCduringtheSEPdidnotshowthattherewasaCIStothesethreevalves.Therefore, theNRChadevaluated AOV745,MOV749AandMOV749Bintheircurrentconfigurations duringboththeTMILessonsLearnedandSystematic Evaluation

Programs, andfoundthemtobeacceptable.

Sincetherewasnoconflicting supporting designbasisinformation (e.g.,UFSAR,elementary drawings) showingthatMOV749AandMOV749BreceiveaCIS,thesevalveswerenotdeclaredinoperable whenitwasdetermined thattheydidnotreceiveaCIS,ashadbeendonewithAOV745.Basedonourreviewofthissituation, RG&Einterprets the60secondmaximumisolation timeaslistedinTechnical Specification Table3.6-1tobevalveclosuretimefollowing ademandtoclose.Thisinterpretation isconsistent withStandardReviewPlan6.2.4,sectionII(n)andhasbeentransmitted totheGinnaStationoperation staff.'Therefore, nochangesarerequiredwithrespecttoMOV749AandMOV749B.Penetration 124aisaclosedsysteminsidecontainment whichisseismicandmissile-protected.

ThecurrentGDC57onlyrequiresamanualorremote-manual valveoutsidecontainment forthisconfiguration.

Thesafetyfunction(i.e.,containment isolation) ofthispenetration ismetinthecurrentconfiguration, evenwithAOV745normallyopen.RG&Ehasthusconcluded thatAOV745doesnotrequireaCIStobeconsidered operablesincethecontainment isolation functionassociated withPenetration 124aisaccomplished bytheclosedsysteminsidecontainment andAOV745(withoutaCIS)outsidecontainment.

Therefore, thecriteriaof10CFR550.73 arenotapplicable tothediscovery thatAOV745doesnotreceiveaCIS.However,becauseourresponsetoitem2.1.4.3intheabovecitedNovember19,1979letterindicated thatwewouldprovideaCIStovalvesinnon-essential penetrations, eventhoughsuchasignalgoesbeyondtherequirements ofGDC57,RG&EcommitstoinstallsuchasignaltoAOV745bytheendofthe1992refueling outage.Inthemeantime, inordertoprovideanotherlevelofassurance ofcontainment isolation, RG&EisplanningtomodifytheEmergency Procedures todirecttheoperators toremote-manually closethisvalvefromtheControlRoomatanappropriate timefollowing receiptofaCIS(e.g.,following immediate actionsofE-0).Theadditionofthisprocedure stepwillbeaccomplished byAugust15,1990.
