Neoclassical impurity transport in the core of an ignited tokamak plasma

摘要

Impurity behaviour in the course of an ignited fusion reactor (ITER FDR) is investigated under the assumption that the impurity fluxed are dominated by neoclassical transport. Equilibrium impurity profiles are evaluated for two temperature profiles and compared with the results for purely anomalous diffusion with a core diffusion of D_an = 0.5M2/3. The neoclassical fluxes are core is below 0.1 m 2/3 and decreases Z of the impurity.
