Extended MHD simulations for application to ITER disruption mitigation techniques

Various disruption scenarios are modeled computationally by use of the CORSICA [1] and NIMROD [2] codes, following the work of Kruger [3] and Strauss [4] with the aim of providing starting-points for investigation of tokamak disruption mitigation techniques [5]. It is found that pressure-driven instabilities previously observed in simulations of DIII-D are verified, and that halo currents from vertical displacements are observed in simulations with implementation of resistive walls for ITER. We discuss implications and plans for simulations of disruption mitigation techniques. We outline validation activities for existing facilities.\\[4pt] [1] J. Crotinger, et al Proc.
