Plasma disruptions in tokamak machines determine the interruption of confinement and the development of loss channels for the thermal and magnetic energies stored within the reactants into the containment structure, posing a threat for the machine’s integrity. In this regard, tokamak design can be well informed by numerical codes modelling the electromagnetic interaction of the MHD plasma with the surrounding conducting structures. The latter provide predictions regarding disruptive plasma instabilities and the ensuing stresses on the walls. The here presented modelling activities have accomplished the self-consistent plasma-wall coupling of the induced (eddy) and source-sink (halo) currents flowing in the machine’s structures during plasma instabilities; the framework leverages the interplay of the non-linear MHD code JOREK with the 3D wall codes STARWALL (thin) and CARIDDI (volumetric). The first reproduced instabilities are shown.
