摘要：

Neoclassical impurity transport is compared with transport calculated from the reactive drift wave model of turbulent transport for an ITER-like [R. Aymar, P. Barabaschi, and Y. Shimomura, Plasma Phys. Controlled Fusion 44, 519 (2002)] scenario. The turbulent transport is inward for both main ions and impurities, but the impurity ion inward transport is much weaker than the main ion inward transport. The neoclassical impurity transport is outward because of temperature screening. The total impurity transport, determined by a balance between turbulent and neoclassical transport, depends sensitively on the charge number of the impurity and the ratio of the ion density and temperature scale lengths, eta(i).
