英文摘要	Simulation studies of core plasmas and edge plasmas are performed in ASIPP to accommodate plasma profiles from core to edge based on physics modeling for the CFETR physics design. The coupling between the modeling for core plasmas and edge plasmas are described. The recent progress of the integrated core-pedestal simulations for core plasmas and the SOLPS simulations for plasmas in pedestal-SOL-divertor region are presented, respectively. In the optimization study for core plasma performance, moderate Z(eff) (similar to 2.2) at pedestal top and a high ratio of density at separatrix to density at pedestal (n(sep)/n(ped) similar to 0.5) are found to be beneficial for the achievement of a high fusion gain in CFLTR hybrid scenarios. The edge plasma simulations using the SOLPS code show that using either neon or argon impurity seeding can reduce the stationary power density on the divertor target to an acceptable level (< 10 MW/m(2)) but Z(eff) at pedestal top is still high (Z(eff) similar to 3). Future works to improve the consistence between the simulations of core and edge plasmas are discussed.
