Finite Element Stress Analysis OF ITER Module 13

Of the 18 module designs in ITER, the US is responsible for three. Each of these modules will be designed to meet requirements established by the ITER international organization (ITER IO). Finite element analysis (FEA) is being utilized to ensure that the module designs are in compliance with the strength requirements established by ITER IO. The strength requirements are defined in terms of maximum allowable stress and strain conditions under loading scenarios determined by ITER IO. These allowable conditions are based on material properties and the expected frequency of the specific loading condition being investigated. This paper presents the FEA approach applied to the design of Module 13. The thermally induced stress distributions caused by ITER operating conditions and internal pressure of cooling fluid were presented. Stresses caused by electromagnetic forces on the module were also presented if available. The stress levels under these conditions were compared to the allowable limits defined by the ITER IO.
