Electro-dynamical analysis of the ITER blanket modules for enhanced vertical passive stabilization

The electro-dynamical analysis of the ITER blanket modules when subject to disruption loads has been performed. Several configurations have been analyzed, considering both the blanket module electrically insulated (this case is considered as a reference) and all toroidal rows of blanket modules (except those corresponding to the upper and equatorial ports levels) electrically connected for vertical stability improvement purposes. In particular the solution with a single strap placed in the equatorial plane of each blanket and the solution with two straps symmetric with respect to this plane have been analyzed. Moreover the influence of the radial position of the straps has been evaluated.
