In next generation tokamak devices (ITER) passive stabilisation of the plasma is required to mitigate the consequences of the plasma vertical displacements and to reduce the occurrence of plasma disruptions. To this end two main design approaches have been considered. The first of these (adopted in the ITER CDA design) consists of copper stabilisation loops (i.e. twin loops) attached to box-shaped blanket segments which are electrically and mechanically separated along the toroidal direction. In the second design approach (for the ITER EDA design), relying on a lower plasma elongation, no specific stabilisation loops are required and the passive stabilisation is achieved by toroidally continuous components. In both cases electrodynamic loads arise in the blanket structures during plasma disruptions and/or vertical displacement events. A comparison between the two design approaches has been carried out from the eddy current and related load distribution viewpoint.
