Abstract
The prediction of electromagnetic loads on the ITER blanket modules during a plasma disruption is considered for two different blanket modules and different disruption events. The key features of the analysis procedure will be presented including the modeling the blanket modules (first wall and shield block), the plasma disruption current, and the integration of these models to produce a high-fidelity electromagnetic simulation that describes a plasma disruption event.

The electromagnetic calculations are performed using the Opera-3d software. The loads due to the eddy currents were calculated for two outboard blanket modules and a number of selected disruption scenarios. Once these loads have been calculated they can also be exported for additional postprocessing to assess the mechanical loading effects.
