摘　　要：A simulation on HCSB-DEMO （helium-cooled solid breeder, HCSB） edge plasma, by using 2D edge plasma transport code SOLPS5.0, is presented. There is 400 MW heat power crossing CIB （core interface boundary）. The heat flux profiles and peak flux at the divertor targets with different boundary densities axe investigated. It is indicated that the HCSB-DEMO divertor should operate at a proper upstream density in order to avoid a high heat flux at the divertor targets. When the upstream density is 0.63x 102~ m-3, the peak heat flux at the divertor targets will be above 17 MW/m2. The cross-field transport, the power crossing CIB and the power fraction taken by electrons and ions and SOL （scrape-off-layer） thickness are analyzed as unknown parameters. It is shown that the peak flux at the divertor target is very sensitive to these parameters. The simulation results will be used in the divertor design for HCSB-DEMO.A simulation on HCSB-DEMO （helium-cooled solid breeder, HCSB） edge plasma, by using 2D edge plasma transport code SOLPS5.0, is presented.
