英文摘要	In-wall-shielding (IWS) blocks located in ITER vacuum vessels (VVs) are used for neutron shielding. They are subjected to complex eddy current electromagnetic forces during plasma disruption events, especially for IWSs of irregular sectors. Reliable evaluation of this kind of electromagnetic force is of great significance for the structural design of IWSs as well as the safety of fusion reactors. In this paper, the eddy current electromagnetic forces on 121 IWS blocks in the irregular sector and their associated conductive parts were numerically calculated based on one of the most important disruption events (the MD UP LIN36ms disruption event). To promote the accuracy of the simulations, the excitation loads during the plasma disruption current were processed from the database simulated by DINA code into the FE (finite element) model of plasma with a special transformation procedure. The results show that the method of applying plasma current from DINA to the finite element model is reasonable and accurate. The electromagnetic forces of the blocks are demonstrated to be reliable. The block with the maximum electromagnetic force is selected for mechanical analysis, and the reliability of its components is verified.
