Self‐consistent modeling of dust particle kinetics and multi‐fluid multi‐species transport of boundary plasmas in ITER is performed with the multi‐physics code DUSTT/UEDGE. Results are presented for the sensitivity of the pedestal and divertor plasmas to the injection rate, size, and source location of the dust particles. The cases of low‐ z and high‐ z dust material injection are compared. The impact of dust ablation on impurity inventory, distribution of ions over ionization states, and electron plasma power losses is studied. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
