Abstract :
The electromagnetic (EM) loads during plasma disruptions represent one of the main concern for the ITER in-vessel components. To reduce their effects on the mechanical structures some blanket and divertor design changes have been recently introduced. The effectiveness of these changes has been checked for some of the most critical disruption events, centred disruptions and vertical displacement event disruptions. In order to evaluate the contribution to the EM loads of the halo currents as well as of the currents induced by the thermal quench, a plasma model has also been developed
