Dynamic amplification of reaction forces in the blanket module attachment during plasma disruption of ITER

The typical inboard and outboard ITER blanket modules attached on vessel portions have been analyzed under the dynamic electromagnetic loading with the ANSYS program. The module and keys on the vacuum vessel come in contact and leave it because of the assembly clearances. The evolution of the contact forces on the keys and the axial reactions in the flexible supports is analyzed. The dynamic amplification factors are calculated and compared for the different temperature, gravity and damping conditions.
