Abstract
The structural integrity of the ITER thermal shield (TS) has been verified by structural analysis. In this paper, the analysis process methodology and demonstration of the structural integrity for the TS are described. The analysis is performed for the TS global models and detailed models, such as supports and joints. TS joints in the shell model are modeled using orthotropic material properties. To verify the structural reliability for the TS, plastic collapse, buckling, ratcheting, and fatigue are assessed in accordance with ASME Section VIII, Div. 2.
