Verification of TOKES simulations against the MGI experiments in JET

The integrated tokamak simulation code TOKES is proposed for estimation of the ITER first wall radiation damage during massive injection of noble gas inside the core for mitigation of the disruptions. Simulations of MGI processes ab initio are almost impossible because of complexity of the problem, but one can get reliable results elaborating the TOKES scenario from JET experiments and applying it for ITER conditions. With this aim the TOKES code is used for simulation of JET shots disrupted with MGI. The TOKES scenario for the thermal quench of MGI at JET and its extrapolation to ITER have been developed basing on analysis of the available JET database and on comparison with the simulations performed.

► The code TOKES is proposed for estimation of the ITER first wall damage during MGI.
► The TOKES code is applied for simulation of two JET shots disrupted with MGI.
► TOKES scenario for TQ of MGI in JET and its extrapolation to ITER are developed.
► The simulation results are in reasonable agreement with selected experiments.
