Structural design and analysis of in wall shielding for ITER

In order to shield the neutron current and reduce the ripple during the ITER fusion reaction process, the in-wall shielding structures have been inserted between the two shells of the ITER vacuum vessel, and the safety of the reaction could be ensured. The conceptual design, the design guideline, the detail design and the assembly scheme for the in-wall shielding have been introduced. Choosing one shielding block which formed the in-wall shielding structure as the research object, its heat-structure coupling analysis has been fulfilled, and component response stress is less than the allowable stress??and the rationality of its structural design has been validated.
