Therefore, ithasbeenassumedthatthecapsuleweldmaterialissimilartothebeltlineweldsintermsofitsmechanical behaviortrend.Theirradiated CharpydataforthecapsuleweldmaterialwasanalyzedusingtheSAMMcFRACcode[McFRAC).

Therefore, thefinalo,wasdetermined usingaweightedaverageofplantspecificandgenericdataconservatively assumingtherewereonlytendatapointsinthedatabaseanalyzedbyOdette,toyieldcr,=17'F.Thisvalueforcr,isrecommended forusein[RG1.99]Margintermcalculations forallofthebeltlineweldmaterials.

Manyoperating powerplantswerebuiltwhencurrentregulations concerning establishment oftheinitialRT~~werenotinforce.Znmanycases,insufficient dropweightandCharpydataareavailable todetermine theRT~~inaccordance withthecurrentSectionXIIoftheASMEcode.Priorto1972,theASMEcoderecpxired thattheaverageofthreeCharpyspecimens beatleast30ft-lb.atadesignated temperature, withnosingleimpactenergylessthan25ft-lb.Thesearetheruleswhichwereusedforthevessel.TheNRCBranchTechnical

12isoverlyconservative forsomematerials anddoesnottakeadvantage oftheuseoflimitedunirradiated norirradiated dataintheanalysis.

GEalsohasagenericmodelwhichisbasedonatransition regionslopeof.5ft-lb./'F.

However,thismodel,liketheNRCmodel,isgenericandlacksstatistical rigor.Neutronirradiation ofpressurevesselmaterials causes:anincreaseinthe30ft-lb.transition temperature 2)aloweringoftheuppershelf3).adecreaseintheslopeofthetransition region[OD86]Inaddition, Odettehasshownthatthetransition regionoccursoveranapproximately constantintervaloftemperature.

Odettepointedoutthatthisfact,inconcertwithacontinuous decreaseofuppershelfenergy(USE),requiresthatthe'transition regionslopemustdecreasewithirradiation.

Theaveragevalueofthetransition temperature range,6T~,isabout200F+45Fforwelds.Thesedata,alongwithOdette'syieldstrengthmodel,canbeusedtoprovideanaccurateestimateoftheRTQ7ofthebeltlineweldmaterials assumingthattheNDTToccursatalowertemperature thanthetemperature atwhichthreeCharpyspecimens wouldexhibit50ft-lbs.ofenergyminus60.Thisassumption isaccurateformostpressurevesselmaterials becausetheNDTTisexpectedtooccuratornearthebrittleness transition regionneartheonsetofthelowershelf.AnalysisoftheLWRASTMA533Bdatabasesubstantiates thisassumption.

Inthe23casesanalyzed, theNDTTwaslessthanorequaltotheRT~~.In15outof23cases,theRT~~wasdetermined fromtheCharpydata.Theaveragedifference betweentheactualRTgp~andtheRTgp7estimated usingtheReference[MA85]approach II 13was8'Fforweldsand10'Fforbasemetal.Theaveragenetdeviation isabout4.3'Fforplateandweld.Asimilaranalysiswasconducted forASTMA302Bdata.Inallofthe17casesanalyzedtheNDTTwaslessthanorequaltotheRT~T.TheRTgpTwasdetermined fromCharpydatain13ofthe17cases.TheaveragebetweentheASMEcodedetermined RT~Tandthatdetermined usingReference
