A.DESCRIPTION OFTECHNICAL SPECIFICATION CHANGESThisLARproposestorevisetheGinnaStationITSassummarized belowandshowninAttachment II.1.LCO3.5.1SR3.5.1.2isrevisedtocorrectthespecified accumulator boratedwatervolumevaluesinordertomatchwiththeassociated accumulator percentlevelvalues.B.BACKGROUND OnFebruary13,1996,theNRCissuedAmendment No.61totheGinnaStationtechnical specifications.

Thisamendment replacedtheexistingGinnaStationtechnical specifications intheirentiretywithITSthatwerebasedonNUREG-1431.

IncludedwithintheITSwastheadditionofspecificaccumulator boratedwatervolumestomatchwiththeexistingaccumulator percentlevelvalues.Thatis,theprevioustechnical specifications alreadyrequiredanaccumulator inventory basedonpercentlevel.ThewatervolumesincubicfeetthatwereaddedtoSR3.5.2.1wereintendedtobethesameaccumulator inventories andwerethosecalledoutintheaccidentanalyses.

However,asidentified inRG&EActionReport97-0960,ithassincebeendetermined thatthewatervolumesasspecified intheITSdonotcorrectly matchupwiththepercentlevelvalues.Thiswasduetoanerrorintheaccumulator wallthickness usedinthecalculation.

Toensurecontinued compliance withtheexistingSR3.5.2.1requirements, RG8'cEiscurrently maintaining RWSTlevelbetween67%and82%level(versusthespecified 50%to82%level).Thisbandwasdetermined basedonmeetingthemostlimitingofthespecified cubicfeetandpercentlevelvalues.RG&EandWestinghouse havesincere-evaluated theaffectedaccidentanalyses(e.g.,smallandlargeLOCAandsteamlinebreaks)usingthecorrectcubicfeetvalueswithrespecttothe50%and82%levelsasspecified inSR3.5.2.1anddetermined anegligible changeresults(i.e.,theresultsareacceptable).

Itshouldbenotedthatasdescribed onITSbasespageB3.5-4,onlyanominalaccumulator levelisusedintheaccidentanalysisduetocompeting effectsofhigherversuslowerlevels.Thatis,theaccidentanalysisdoesnotusetheupperandloweraccumulator volumes,onlyanaverage.Consequently, thepurposeofthisLARistocorrecttheconversion error.Nomodifications arerequiredinordertoimplement thisLAR.C.JUSTIFICATION OFCHANGESThissectionprovidesthejustification forallchangesdescribed inSectionAaboveandshowninAttachment II.Thejustifications areorganized basedonwhetherthechangeis:morerestrictive (M),lessrestrictive (L),administrative (A),ortherequirement isrelocated (R).Thejustifications listedbelowarealsoreferenced inthetechnical specification(s) whichareaffected(seeAttachment II).Itisnotedthatthereareonlyadministrative changesassociated withthisLAR.C.1miniraiv1.Theaccumulator boratedwatervolumeincubicfeetiscorrected inordertomatchwiththespecified accumulator percentlevelinSR3.5.2.1.Thischangeisrequiredtocorrectanerrorthatwascausedbyusinganincorrect accumulator wallthickness.

Theaffectedaccidentanalyses(e.g.,smallandlargeLOCAandsteamlinebreaks)havebeenre-evaluated byRG&;EandWestinghouse usingthecorrectcubicfeetvalueswithrespecttothe50%and82%levels.Theresultsindicatethattherewasanegliglible changesuchthatallrequirements withrespecttotheemergency corecoolingsystemremainmet(e.g.,10CFR50,AppendixK).Therearenotlessrestrictive (L),morerestrictive (M),orrelocated (R)changesassociated withthisLAR.

D.SIGNIFICANT HAZARDSCONSIDERATION EVALUATION TheproposedchangestotheGinnaStationTechnical Specifications asidentified inSectionAandjustified inSectionChavebeenevaluated withrespectto,10CFR50.92(c)andshowntonotinvolveasignificant hazardsconsideration asdescribed below.Thissectionisorganized basedonSectionCabove.D.1linfminirihnTheadministrative changesdiscussed inSectionC.ldonotinvolveasignificant hazardsconsideration asdiscussed below:Operation ofGinnaStationinaccordance withtheproposedchangesdoesnotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated.

Thechangeisonlytocorrectaconversion errorwithrespecttoaccumulator boratedwatervolume.Thisdoesnotincreasetheprobability ofanyaccidentpreviously evaluated sincetheaccumulator watervolumeprovidesmitigation capability only(i.e.,doesnotinitiateanyaccident).

Theaffectedaccidentanalyseswithrespecttotheaccumulator (e.g.,smallandlargeLOCAandsteamlinebreak)havebeenre-evaluated usingthecorrectaccumulator watervolumevalueswithacceptable results.Therefore, thesechangesdonotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously analyzed.

Operation ofGinnaStationinaccordance withtheproposedchangesdoesnotcreatethepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated.

Theproposedchangesdonotinvolveaphysicalalteration oftheplant(i.e.,nonewordifferent typeofequipment willbeinstalled) orchangesinthemethodsgoverning normalplantoperation.

GinnaStationoperators verifyaccumulator watervolumeviapercentlevel(versuscubicfeet)whichremainsunchanged.

Thus,thischangedoesnotcreatethepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated.

Operation ofGinnaStationinaccordance withtheproposedchangesdoesnotinvolveasignificant reduction inamarginofsafety.Theproposedchangesonlycorrectaconversion error.Theerrorhasbeenre-evaluated withacceptable results.Assuch,noquestionofsafetyisinvolved, andthechangedoesnotinvolveasignificant reduction inamarginofsafety.Basedupontheaboveinformation, ithasbeendetermined thattheproposedchangestotheGinnaStationTechnical Specifications donotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated, doesnotcreatethepossibility ofanewordifferent kindofaccidentpreviously evaluated, anddoesnotinvolveasignificant reduction inamarginofsafety.Therefore, itisconcluded thattheproposedchangesmeettherequirements of10CFR50.92(c)anddonotinvolveasignificant hazardsconsideration.
