Abstract.  A concerted effort has been launched to accurately predict electromagnetic loads in ITER due to plasma major disruptions (MDs) and vertical displacement events (VDEs) using the Tokamak Simulation Code (TSC) and compare the predictions made earlier using the DINA code. In this effort the TSC model is first benchmarked with experimental observations in ASDEX Upgrade and NSTX. The upgraded TSC model is then used in predictive simulations for ITER for different MD and VDE scenarios with upward or downward plasma motion and fast or slow current quench depending on the post thermal quench plasma core temperature. The simulation results are compared with earlier DINA predictions.
