Abstract
Predictive simulations have been performed for the ignition capability of ITER in the EDA design, using a toroidal drift wave model with one auxiliary ion species. The dynamics of trapped electrons, main ions and auxiliary ions with respective temperatures has been treated self-consistently including a full transport matrix. The code has been run in two modes. First the auxiliary ions are treated as impurities with the alpha power deposited directly on electrons. In this mode the results are similar to those previously obtained by the critical electron temperature gradient model but with the scaling of T{sub E} with Z{sub eff} dependent on the collision frequency. In the second mode the alpha power was given to the auxiliary ions which then became hot alphas. No significant degradation of the confinement occurred. 10 refs, 1 tab.
