Abstract :
Inthisresearch,theoptimizationoftheworthshapeofaxiallyvariablestrengthcontrolrods(AVSCRs)isperformedtoprovideoptimalperformancetotheAVSCRsforthepowermaneuveringofPWRs.Theoptimizationobjectiveisminimizingaxialoffset(AO)violationoftargetboundariesduringthepowermaneuvering,andtheobjectivefunctionsfortheoptimizationarerelationshipsbetweenAOvariationandaxialworthshapeoftheAVSCRs.However,inthiscase,ananalyticobjectivefunctiondoesnotexist,andtheresponseforinputcanonlybeevaluatedbycomputersimulation.Therefore,asimulationoptimizationmethodologyisused.Theresponsesurfacemethodology(RSM)isadoptedandobjectivefunctionsareevaluatedwithatypical100-50-100%,2-6-2-14hpatternofdailyload-followpowermaneuveringusingreactorsimulationcode.TheoptimizationresultshowsthattheoptimizedAVSCRshavegoodperformanceontheAOcontrol.TheviolationoftheAOtargetboundaryduringthepowermaneuveringisminimized,andconsequentlytheAOisregulatedwellwithintheAOtargetbandduringthepowermaneuvering.
