Abstract

Self-consistent modeling of ITER has been carried out using the 1.5D BALDUR integrated predictive modeling code. In these simulations, a core transport model is described by a combination of an anomalous transport and a neoclassical transport. An anomalous transport is calculated using the Multimode (MMM95) core transport model, while a neoclassical transport is computed using the NCLASS model. At the reference design point, it is found that ITER fusion power production improves with the increase of pedestal temperature, average electron density, and auxiliary heating power. However, the power production reduces with the increase of impurity content. For the variation of the density and auxiliary heating power, the fusion Q increases linearly with both parameters. It is also found that the sawtooth mixing radius tends to decreases with increasing of pedestal temperature, average electron density and auxiliary heating power; however, it increases with impurity content. In addition, the sawtooth frequency tends to increase with the increase of heating power; but decrease with pedestal temperature.
