The mitigation of thermal and mechanical loads during disruptions is an urgent task to be solved for ITER to ensure the integrity of Plasma-Facing Components (PFC). However, extreme loads are already an issue for present day machines like JET and in particular for the new ITER-like wall implemented in JET which will have the material used in ITER for DT operation. Reduction of such loads to tolerable values is needed, thereby, the generation of high-energy electrons (RE) is of special concern. RE in JET can carry currents of up to 50% of plasma current before the disruption, leading to a fast and localised deposition of several MJ on plasma-facing components. Disruption mitigation has to fulfil three aims: mitigation of forces by halo and eddy currents, mitigation of convective heat loads during the thermal quench, mitigation of heat loads by runaway electrons. ITER needs a reduction of the forces by a factor 3-5 and a reduction of the thermal loads on Be and W components by a factor 10 to ensure integrity and lifetime of PFC.
