In a tokamak-type fusion device, the presence of large magnetic fields and the plasma disruptive instabilities generate electromagnetic-type phenomena in transient conditions which lead to strong induced eddy currents and body loads. These electromagnetic loads must be correctly accommodated in the engineering design of all reactor components. In particular, the plasma disruptions have a significant impact on the mechanical design of the internal reactor components, such as the multi-segmented first wall, and of their supports. Fully three-dimensional dynamic analyses are required due to the geometrical complexity of the conducting and plasma regions and to the transient nature of the phenomena, from both the electrical and mechanical standpoints.
