The prediction of electromagnetic loads on blanket module 1 of the ITER device during a plasma disruption event is considered. This analysis is performed for a number of design variations (of the blanket module) and different disruption events.

The key features of the analysis procedure will be presented including the geometric description of the blanket module composed of a first wall, shield block, and vacuum vessel. The modeling of the plasma current will also be described.

The electromagnetic analyses are performed using the Opera-3d software. The transient eddy currents are first calculated, from which the electromagnetic loads are determined. Once these loads have been calculated they can also be exported for additional post-processing to assess the mechanical loading effects.
