Containment leakagetestingisnot,requiredperL.D.White,Jr.lettertoDennisL.Ziemann,USNRCdatedSeptember 21,1978.3.6-10Proposed Attachment BPage1of2Attachment BThepurposeofthisamendment istoreviseseveralpenetration listingsinTechnical Specification Table3.6-1tosupportanIntegrated LeakRateTest(ILRT)oftheGinnaStationcontainment duringthe1993Refueling Outage.Asaresultofpreparing forthistest,RG&Edetermined thatadiscrepancy existedbetweentheTechnical Specifications andtheNRCapprovedIn-Service Test(IST)Program.Currently, Technical Specification Table3.6-1identifies twomanualvalves(820and204A)ascontainment isolation valves(CIVs)forPenetration 112.Aspartofthethird10yearISTprogramsubmittal forGinnaStation,RG&Eidentified thatvalves820and204AwouldberemovedfromtheISTprogramsincetheirpressureandcontainment isolation functions werebeingperformed byvalves200A,200B,and202(Reference a).TheNRCacceptedthischangebyReference (b).Therefore, RG&ErequeststhatTable3.6-1bechangedtoreplacevalves820and204AwithAOVs200A,200B,and202.Inaddition, reliefvalve203,whichislocatedbetweencontainment isolation valves200A,200B,202and371forthispenetration, willbeaddedtothetable.Allfivevalvesarecurrently intheGinnaStationAppendixJtestingprogram.ThischangewillenablePenetration 112tomeettheexplicitrequirements ofGDC56.ThecurrentTable3.6-1Note17willalsobedeletedsinceitisnolongerused.Technical Specification Table3.6-1alsoidentifies amanualvalveinserieswithanair-operated valveastheCIVsforPenetrations 206,207,321,and322.Thesepenetrations containthesteamgenerator (S/G)blowdownandblowdownsamplepiping.RG&ErequeststhatthemanualvalvesberemovedfromTable3.6-1sincetheS/Gtubesandsecondary sideprovideonecontainment barrier.Thesepenetrations willthenbetreatedanalogous tothemainsteamandfeedwater lineswhichareofsimilarconfiguration.

Table3.6-1Note17willthenberevisedandaddedtothesefourpenetrations toreflecttheuseoftheS/Gtubesandsecondary sideasacontainment boundary.

Table3.6-1Note7willalsobedeletedfromthesefourpenetrations.

Thisnotewasoriginally appliedtotheS/Gblowdownlinessincetheypenetrate themissileshieldinsidecontainment inordertoreachtheS/Gs.However,theNRChasapprovedtheuseof"leak-before-break" (LBB)withrespecttolargediameterReactorCoolantSystempipingatGinnaStation(Reference c).TheuseofLBBexcludestheconsideration ofthedynamiceffectsassociated withpostulated piperupturesper10CFR50,AppendixA,GDC4.Inaddition, plantwalkdowns andareviewofSystematic Evaluation Program(SEP)TopicIII-S.A,EffectsofPipeBreakonStructures, Systems,andComponents InsideContainment, (Reference d)confirmsthateventhoughthesefourlinespenetrate themissileshield,theyarenotsusceptible toanyhighenergylinesources.Thisincludestheaffectsofpipewhipandjetimpingement.

Therefore, thedynamiceffectsassociated withanyhighenergylinebreakinsidecontainment doesnotrequireconsideration withrespecttotheS/Gclosedsystem.Theblowdownlinesinsidecontainment arealsoSeismicCategoryIandSafetyClass2.Consequently, thelinesareconsidered missileprotected basedontheirpresentlocationandhavethenecessary closedsystemdesignrequirements.

Attachment BPage2of2RG&Ewillalsoeliminate 10CFR50AppendixJtestingrelatedtothefourAOVsforPenetrations 206,207,321,and322sincetherearenotanyrequirements toperformthistesting.Instead,RG&Ewillhydrostatically testthesevalvesinaccordance with'theoriginalrequirements asoutlinedintheapprovedthird10yearISTprogramforGinnaStation(IWV-3421 through3425)asaminimum.Thiswillprovidethenecessary assurance thatthevalveswillperformtheirrequiredisolation function.

Thesechangeswillbedocumented intheGinnaStationISTProgramwhichwillbesubmitted totheNRCfollowing theconclusion ofthe1993Refueling OutagesinceRG&Eexpectstomakeseveralotherunrelated ISTProgramchangesatthattime.ThesechangeswillnotrequireNRCapprovalpriortoimplementation.

Inaccordance with.10CFR50.91,thesechangestotheTechnical Specifications havebeenevaluated todetermine iftheoperation ofthefacilityinaccordance withtheproposedamendment would:1.involveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated; or2.createthepossibility ofanewordifferent kindofaccidentpreviously evaluated; or3.involveasignificant reduction inamarginofsafety.Theseproposedchangesdonotincreasetheprobability orconsequences ofapreviously evaluated accidentorcreateanewordifferent typeofaccident.

Furthermore, thereisnoreduction inthemarginofsafetyforanyparticular Technical Specification.

Thedetailedchangesaredescribed inAttachment C.Therefore, Rochester GasandElectricsubmitsthattheissuesassociated withthisAmendment requestareoutsidethecriteriaof10CFR50.91;andanosignificant hazardsfindingiswarranted.
