The space between the double walls of ITER Vacuum Vessel is filled with pre-assembled or modular shield blocks called "in-wall shielding". It has two main functions; one is to provide an effective neutron shielding and the other to reduce the toroidal field ripple in the outboard region. The in-wall shielding is designed to minimize electromagnetic forces acting on the shield blocks. The electromagnetic forces have been calculated with the latest disruption scenarios. Magnetization forces have also been calculated for ferromagnetic inserts. Structural integrity has been validated by structural analyses.
