MHD-calibrated ELM model in simulations of ITER

Simulations of ITER have been carried out using the JETTO integrated modeling code in which theory motivated models are used for the H-mode pedestal and for the stability criteria that lead to the ELM crashes. In the simulations, ELM crashes are triggered either by ballooning or peeling modes. The equilibrium and MHD stability analyses codes, HELENA and MISHKA, are used to evaluate the edge stability of the plasma just prior to an ELM crash in order to calibrate and confirm the validity of the stability criteria used to trigger ELMs in the JETTO simulations. In the simulations, core transport is calculated using an anomalous transport model such as the Mixed Bohm/gyro-Bohm model, while ion thermal neoclassical transport is used for the pedestal region. Studies are carried out varying the auxiliary heating power and the width of the pedestal in order to examine sensitivity of fusion Q to these parameters.
