Abstract

As part of the ongoing EU DEMO studies, this work is focused on the analysis of the EM forces acting on a DEMO reactor configuration based on Multi Module Segment (MMS) design with respect to module´s dimension. The EM loads both on the single module as well as on the complete blanket segment is performed by means of four different FEM models built varying the poloidal and toroidal dimension of the modules. The eddy currents, electromagnetic forces and moments are computed during a major central disruption scenario with a linear current quench of 42 ms using the ANSYS finite element software.
