Thefuelcladding, reactorpressurevesselandprimarysystempipingaretheprincipal barrierstothereleaseofradioactive materials totheenvirons. | |||
SafetyLimitsareestablished toprotecttheintegrity ofthesebarriersduringnormal.plantoperations andanticipated transients. | |||
Thefuelcladdingintegrity SafetyLimitis'setsuchthatnofueldamageiscalculated tooccurifthelimitisnotviolated. | |||
Becausefueldamageisnotdirectlyobservable, astep-back approachisusedtoestablish aSafetyLimitsuchthattheMCPisnotlessthanthelimitspecified inSpecification 2.l.2forbothGEandn..fuel.MCPRgreaterthanthespecified limitrepresents aconser-vativemarginrelativetotheconditions requiredtomaintainfuelcladdingintegrity. | |||
Thefuelcladdingisoneofthephysicalbarrierswhichseparatetheradioactive materials fromtheenvirons. | |||
Theintegrity ofthiscladdingbarrierisrelatedtoitsrelativefreedomfromperforations orcracking. | |||
Al-thoughsomecorrosion oruserelatedcrackingmayoccurduringthelifeofthecladding, fissionproductmigration fromthissourceisincrementally cumulative andcontinuously measurable. | |||
Fuelcladdingperforations, however,canresultfromthermalstresseswhichoccurfromreactoroperation significantly abovedesignconditions andtheLimitingSafetySystemSettings. | |||
Whilefissionpro"ductmigration fromcladdingperforation isjustasmeasurable asthatfromuserelatedcracking, thethermally causedcladdingperforations signalathreshold beyondwhichstillgreaterthermalstressesmaycausegrossratherthanincre-mentalcladdingdeterioration. | |||
Therefore, thefuelcladdingSafetyLimitisdefinedwithamargintotheconditions whichwouldproduceonsetoftransition boiling,MCPRof1.0.Theseconditions represent asignificant departure fromthecondition intendedbydesignforplannedoperation. | |||

SAFETYLIMITSBASES2.1.2THERMALPOWERHihPressureandHihFlowOnsetoftransition boilingresultsinadecreaseinheattransferfromthecladand,therefore, elevatedcladtemperature andthepossibility ofcladfailure.However,theexistence ofcriticalpower,"orboilingtransition, isnotadirectlyobservable parameter inanoperating reactor.Therefore, themargintoboilingtransition iscalculated fromplantoperating parameters suchascorepower,coreflow,feedwater temperature, andcorepowerdistribution. | |||
Themarginforeachfuelassemblyischaracterized bythecriticalpowerratio(CPR),whichistheratioofthebundlepowerwhichwouldproduceonsetoftran-sitionboilingdividedbytheactualbundlepower.Theminimumvalueofthisratioforanybundleinthecoreistheminimumcriticalpowerratio(MCPR).TheSafetyLimitMCPRassuressufficient conservatism intheoperating MCPRlimitthatintheeventofananticipated operational occurrence fromthelimitingcondition foroperation, atleast99.9Xofthefuelrodsinthecorewouldbeexpectedtoavoidboilingtransition. | |||
Themarginbetweencalculated boilingtransition (MCPR=1.00)andtheSafetyLimitMCPRisbasedonade-tailedstatistical procedure whichconsiders theuncertainties inmonitoring thecoreooerating state.Onespecificuncertainty includedinthesafetylimitistheuncertainty inherentintheXN-3criticalpowercorrelation. | |||
XN-NF-524 describes themethodology usedindetermining theSafetyLimitMCPR..X,HsE.RV S.TheXN"3'critical powercorlationisbasedonasignificant bodyofprac-ticaltestdata,providing a'ghdegreeofassuranCe thatthecriticalpowerasevaluated bythecorrelat'on iswithinasmallpercentage oftheactualcriti-calpowerbeingestimated. | |||
eassumedreactorconditions usedindefiningthesafetylimitintroduce conservatism intothelimitbecauseboundinghighradialpowerfactorsandboundingflatlocalpeakingdistributions areusedtoestimatethenumberofrodsinboilingtransition. | |||
Stillfurtherconservatism isinducedbythetendencyoftheXN-3correlation tooverpredict thenumberofrodsinboilingtransition. | |||
Theseconservatisms andtheinherentaccuracyoftheXN-3correlation provideareasonable degreeofassurance thatduringsus-tainedoperation attheSafetyLimitMCPRtherewouldbenotransition boilinginthecore.Ifboilingtransition weretooccur,hereisreasontobelievethattheintegrity ofthefuelwouldnotnecessarily becompromised. | |||
Significant testdataaccumulated bytheU.S.NuclearRegulatory Commission andprivateor-ganizations indicatethattheuseofaboilingtransition limitation toprotectagainstcladdingfailureisaveryc'onservative approach. | |||

2.1SAFETYLIMITSBASES
2.0INTRODUCTION
Thefuelcladding, reactorpressurevesselandprimarysystempipingaretheprincipal barrierstothereleaseofradioactive materials totheenvirons.
SafetyLimitsareestablished toprotecttheintegrity ofthesebarriersduringnormal.plantoperations andanticipated transients.
Thefuelcladdingintegrity SafetyLimitis'setsuchthatnofueldamageiscalculated tooccurifthelimitisnotviolated.
Becausefueldamageisnotdirectlyobservable, astep-back approachisusedtoestablish aSafetyLimitsuchthattheMCPisnotlessthanthelimitspecified inSpecification 2.l.2forbothGEandn..fuel.MCPRgreaterthanthespecified limitrepresents aconser-vativemarginrelativetotheconditions requiredtomaintainfuelcladdingintegrity.
Thefuelcladdingisoneofthephysicalbarrierswhichseparatetheradioactive materials fromtheenvirons.
Theintegrity ofthiscladdingbarrierisrelatedtoitsrelativefreedomfromperforations orcracking.
Al-thoughsomecorrosion oruserelatedcrackingmayoccurduringthelifeofthecladding, fissionproductmigration fromthissourceisincrementally cumulative andcontinuously measurable.
Fuelcladdingperforations, however,canresultfromthermalstresseswhichoccurfromreactoroperation significantly abovedesignconditions andtheLimitingSafetySystemSettings.
Whilefissionpro"ductmigration fromcladdingperforation isjustasmeasurable asthatfromuserelatedcracking, thethermally causedcladdingperforations signalathreshold beyondwhichstillgreaterthermalstressesmaycausegrossratherthanincre-mentalcladdingdeterioration.
Therefore, thefuelcladdingSafetyLimitisdefinedwithamargintotheconditions whichwouldproduceonsetoftransition boiling,MCPRof1.0.Theseconditions represent asignificant departure fromthecondition intendedbydesignforplannedoperation.
TheMCPRfuelcladdingintegrity Safetylimitassuresthatduringnormaloperation andduringantici-patedoperational occurrences, atleast99.9Xofthefuelrodsinthecoredonotexperience transition boiling(ref.XN-NF-524(A)).

SAFETYLIMITSBASES2.1.2THERMALPOWERHihPressureandHihFlowOnsetoftransition boilingresultsinadecreaseinheattransferfromthecladand,therefore, elevatedcladtemperature andthepossibility ofcladfailure.However,theexistence ofcriticalpower,"orboilingtransition, isnotadirectlyobservable parameter inanoperating reactor.Therefore, themargintoboilingtransition iscalculated fromplantoperating parameters suchascorepower,coreflow,feedwater temperature, andcorepowerdistribution.
Themarginforeachfuelassemblyischaracterized bythecriticalpowerratio(CPR),whichistheratioofthebundlepowerwhichwouldproduceonsetoftran-sitionboilingdividedbytheactualbundlepower.Theminimumvalueofthisratioforanybundleinthecoreistheminimumcriticalpowerratio(MCPR).TheSafetyLimitMCPRassuressufficient conservatism intheoperating MCPRlimitthatintheeventofananticipated operational occurrence fromthelimitingcondition foroperation, atleast99.9Xofthefuelrodsinthecorewouldbeexpectedtoavoidboilingtransition.
Themarginbetweencalculated boilingtransition (MCPR=1.00)andtheSafetyLimitMCPRisbasedonade-tailedstatistical procedure whichconsiders theuncertainties inmonitoring thecoreooerating state.Onespecificuncertainty includedinthesafetylimitistheuncertainty inherentintheXN-3criticalpowercorrelation.
XN-NF-524 describes themethodology usedindetermining theSafetyLimitMCPR..X,HsE.RV S.TheXN"3'critical powercorlationisbasedonasignificant bodyofprac-ticaltestdata,providing a'ghdegreeofassuranCe thatthecriticalpowerasevaluated bythecorrelat'on iswithinasmallpercentage oftheactualcriti-calpowerbeingestimated.
eassumedreactorconditions usedindefiningthesafetylimitintroduce conservatism intothelimitbecauseboundinghighradialpowerfactorsandboundingflatlocalpeakingdistributions areusedtoestimatethenumberofrodsinboilingtransition.
Stillfurtherconservatism isinducedbythetendencyoftheXN-3correlation tooverpredict thenumberofrodsinboilingtransition.
Theseconservatisms andtheinherentaccuracyoftheXN-3correlation provideareasonable degreeofassurance thatduringsus-tainedoperation attheSafetyLimitMCPRtherewouldbenotransition boilinginthecore.Ifboilingtransition weretooccur,hereisreasontobelievethattheintegrity ofthefuelwouldnotnecessarily becompromised.
Significant testdataaccumulated bytheU.S.NuclearRegulatory Commission andprivateor-ganizations indicatethattheuseofaboilingtransition limitation toprotectagainstcladdingfailureisaveryc'onservative approach.
Muchofthedatain-dicatesthatLMRfuelcansurviveforanextendedperiodoftimeinanenviron-mentofboilingtransition.
