Dominion's responsetothe RAI questionsisprovidedherein.
Background
AppendixBof DOM-NAF-2-A documents Dominion's qualificationoftheWRB-1correlationwiththe VIPHE-Dcode.TableB.8-1liststhe departure from nucleate boilingratio(DNBR)designlimitof1.17for VIPRE-DIWRB-1,whichis thevaluethatyieldsa 95%non-DNB probabilityata95%confidencelevel(95/95 limit).AppendixBalsoincludesarestrictionthatstates"VIPRE-DIWRB-1willnotbeusedforfuelwithlessthan13"mixingvanegridspacing."Thepurposeofthisrestrictionwasto preclude theuseofthe VIPRE-DIWHB-1 code/correlation with Westinghousefuelwith IntermediateFlowMixingVanegrids(IFM),whichhaveanominal13"grid spacing.Therestriction was originallyplacedonWRB-1intheissuanceoftheSafety EvaluationReport(SER)forthe COBRAlWRB-1topicalreport, VEP-NE-3-A (Reference6).Whenthe VIPRE-Dfleetreportwasdeveloped,therestrictionfromthe COBRASERwasincludedinthe WRB-1 qualification in AppendixBof DOM-NAF-2-A (Reference 2).Page1of8 SerialNo.09-5288 Docket Nos.50-305/336/423/338/339/280/281 Attachment In Reference7theNRCissueda license amendmentfortheIndianPoint Nuclear GeneratingUnitNo.3(IP3)to accommodate the transition from VANTAGE5fuel withoutIFMsto VANTAGE+withIFMsforCycle10.In Section2.3ofthe safety evaluation for that amendment,theNRC staff stated:"TheWestinghouserodbundlecritical heatflux(CHF)correlation,WRB-1, predicts critical heatfluxinrodbundles based on subchannellocalfluidconditions.Thiscorrelationwas initially approved for the standard 14X14,15X15andthe17X17 standardWestinghousefuel(lI\lCAP-8762).
Evolution of the standard17X17and15X15fuelhavebeen developed by Westinghouseandtheir behavior simulatedbyusingan NRC-approved scalingtechnique.Thisscalingtechniquewas validated for all four of the different17X17fueltypes,but notforthe15X15OFAand the VANTAGE+(w/IFMs)fuel.Notestingwas conductedtoverifythatthe scaling technique appliedtothe15X15 standardfuel;however, cycle 10 analyseshasshownthatthereis substantialdeparturefrom nucleete boiling ratio(DNBR)margin.Consequently,untilsuchtime asfueltestsare conductedonthe15X15VANTAGE+(w/IFMs)tovalidatethe scalingtechniqueand the applicability oftheWRB-1correlation,[it]is acceptableforthe upcoming cycle-,0only.Also,DNBanalyses must be submittedtothe staff for review and approval priortocycle 11." Westinghouse conducted confirmatoryDNBtestingonthe 15X1'5 VANTAGE+fuel designwithIFMsin December1998and January1999.The DNB test results were discussedwiththeNRCduringaMarch17,1999meeting.
documented this meetingina lettertotheNRCdatedMarch29,1999 (Reference8).The measured and predictedcriticalheatfluxfortherangeofthe experimental data wereusedto statistically determine the 95/95%DNBRlimit.Thetestdata yielded a limiting DNBRvalueof1.114,whichislessthantheWRB-1designlimitof1.17.The resultsofthis testing demonstrated thattheuseoftheWRB-1 correlationforthe 15X15 VANTAGE+fuelwithIFMswas conservative and confirmed its applicabilityforthisfueltype.
Westinghouse concludedthattheDNB tests verified the applicationoftheWRB-1 correlationwitha95/95 correlationlimitof1.17tothe 15X15 VANTAGE+fuel.Subsequently,inRefer,ence9theNRCissueda license amendment to remove a footnoteintheIP3 TSs stating"Current DNB analysis contains adequate margin forCycle10.Prior to achieving criticalityinCycle11,theDNB analysis must be reviewed and approvedbytheNRCstaff."Inthe associatedSER,theNRC staff stated:"TheNRC staff reviewedtheconditions of Amendment 175 safety evaluation and the presentation oftheDNBtestresults documented in a letterfromWestinghousedatedMarch29,1999.Therestrictioninthe footnote ofTSSection3.1 was intendedtoensurethat adequate DNBmarginwould exist on cycle-specificbasisuntilthefuel vendorPage2of8 SerialNo.09-5288 Docket Nos.50-305/3:36/423/338/339/280/281 Attachment demonstrated the applicability oftheWRB-1correlation tothe15X15VANTAGE+fueldesign.The staff reviewed the licensee's amendment requestandthe documentation oftheDNBtests pertormea by Westinghouse and determinedthat,becausethe newtestdata yielded a DNBR lowerthanthe bounding limit of 1.17,theWRB-1correlationis applicabletothe15X15VANTAGE+fuel;therefore,use oftheWRB-1 correlation is acceptablefor15X15VANTAGE+fuel beyondCycle10and removal ofthefootnoteisacceptable.TheDNBtesting obviates the needforusingthescalingtechnique;therefore,anyquestion astothe acceptability of thistechniqueisno longerrelevant."Thus,theNRCapprovedtheapplicationofthe Westinghouse WRB-1 correlation with 95/95 correlationlimitof1.17tothe15X15 VANTAGE+fuelwithIFMs.
Westinghouse submittedReference10totheNRC,which described evaluationsperformedforthe15x15Upgradefueldesign.Thissubmittalservedas Westinghouse notificationtotheNRC,asrequiredbytheSERon WestinghouseFuelCriteria EvaluationProcess(FCEP),thatthe NRC-approvedprocessin WCAP-12488-A (Reference11)wasusedforthevalidationoftheWRB-1DNBcorrellation applicability tothe15X15 Upgradefue!design.The Westinghouse FCEP specifies the guidelinesrelevantto determine correlation applicabilitytoanewgriddesign.In Reference 10, Westinghousepresentedtheresultsofthe evaluationprocessand concludedthattheWRB-1DNBcorrelationwith95/95correlationlimitof1.17andthe associated correlationrangesare acceptableforapplicationtothe15X15Upqradefuel assembly design.Dominion employed a two-stepprocesstoconfirmtwo necessary methodology elementsforanalysisofthe15x15Upgradedesign.First,itwas necessarytoconfirm the applicabilityofthe qualificationoftheVIPRE-DIWRB-1 qualification as documented in AppendixBof DOM-f\IAF-2-Atothe Westinghouse 15X15 Upgradefuelproduct.The second elementwasto supportremovalofthe13"gridspacingrestriction.Asafirststep,Dominionreplicatedthe Westinghouse evaluationofthe confirmatoryCHFtestdataandprovidedtheresultsofthisevaluationtotheNRCin References1and3.Reference 1 summarizedtheDominionresultsinnarrativeterms.
Reference3providedthedetailed numerical and technical descriptionofthe Westinghouse proprietary dataanddataanalysis.No significant differenceswerefoundbetweenthe Westinghouse and VIPRE-Dresults.Theapplicationof VIPRE-DIWRB-1 with H5/95DNBRlimitof1.17was demonstratedtobe conservativeforgrid spacingsof13"for15X15fuel(i.e.,15X15fuelwithIFMs).Thesecondstepoftheprocessappliesthe conclusionsofthe Westinghouse FCEP evaluationforthe15X15Upgradein Reference 10.Therefore,Dominionhasconcludedthatthe VIPRE-DIWRB-1designlimitof1.17and associated statisticscanbe conservativelyappliedtothesafetyanalysisofthe Westinghouse 15X15 Upgrade fuel productwithIFMs.Page3of8 SerialNo.09-5288 Docket Nos.50-305/336/423/338/339/280/281 AttachmentItiswith respecttothe'first step describedintheabove paragraphthattheNRC staff providedanRAIto completethereviewofthe proposed change in References1and3.Dominion's responsetotheRAI questionsisprovidedbelow.NRCQuestion1 11120109 supplement, page 4 of 8, Equation 2, reference is madetothe T-statistic test.It appears that this shouldbethe F-Statistictest.The same appliesinthe sentence above the equation,"comparing T statistic" should be"comparing F-statistic.

Attachment The qualificationofthe VIPRE-DIWRB-1 code/correlation in AppendixBof2-Autilized945datapointsfrom19test series(n).Normally,the number of degrees of freedom(N)wouldbethetotal numberofdataminusone(n-1).
However, because Westinghouse used these experimentaldatato correlatethe12 constants that appearintheWRB-1 correlation,thetotal number of degrees of freedom was corrected to account forthis.Thus, the standard deviationofthe database in Appendix B (aM/p)was corrected accordingly to accountforthisreduced number of degrees of freedom.EquationB.6.2of Reference2N=n-1-12 O"N=O"M/P'[(n-1)/N]%The DNBR designlimitforthetestdatafrom Test100with VIPRE-DIWRB-1 code/correlation is calculated as describedinTable1of Reference3.The calculations in Table1are identical to those described in TableB.6-2in AppendixBofA.In Table1,theStanclardDeviation(sigma)ofthetestdatais calculatedusingn-1.The number of degrees of freedomisthetotal numberofdataminusone.No additional correctiontothe degrees of freedom is necessary to accountforthe correlationofthe 12 constants.
Hence, the correctionfactor,(n-1)/N,is identically1(one).The specific responsestothe questionsarethen:(a)The standard deviationofthe sample population, sigma or aM/p, is determinedusingn-1inthe denominator.(b)The standard deviationofthe databasemaybe corrected to accountfora reduced number of degrees of freedom.The number of degrees of freedomisthetotal numberofdataminusone.No additional correction to the degrees of freedom is necessary to accountforthe correlationofthe 12 constants.Thus,for Test100,the number of degrees of freedom,N,is equalton-1.(c)The Corrected Standard Deviation, ON, is determined by multiplying the Standard Deviationofthesample, aM/p,bythe correction factor, which istheratioof(n-1)IN.Thevalueofthis correction factor is identically one.Thus,the Corrected StandardDeviationisequaltothe Standard Deviationofthe sample.The purpose of presenting the calculationofthe DNBR designlimitfor Test100as described in Table1of Reference3isto provide a calculation comparableinallwaystothe established method of TableB.6-2in AppendixBof DOM-NAF-2-A.Page5of8 SerialNo.09-5288DocketNos.
