Divertor Modelling for Conceptual Studies of Tokamak Fusion Reactor FDS-Ⅲ

摘要

Divertor modelling for the conceptual studies of tokamak fusion reactor FDS-Ⅲ is carried out by using B2.5-EIRENE(SOLPS5.0) code package. The modelling is proformed by taking real MHD equilibrium, divertor geometry and real plasma species with D-T mixture, He ash and Carbon impurities into account. The profiles of plasma temperature and heat fluxes at the target plates have been obtained, the modelling results also show the fluxes of Carbon impurities from physical and chemical sputtering to the core plasma through separatrix. The analysis to the power balance of a particle has been done based on the modelling results.
