Abstract
A structural analysis of the International ThermonuclearExperimental Reactor (ITER) vacuum vessel's lower port region waspresented by means of a finite element analysis method. The purposeis to evaluate the stress and displacement level on this structureunder various combinations of five designed loads, including thegravity of the vacuum vessel, seismic loads, electromagnetic loads,and possible pressure loads to ensure structural safety. Thecyclic symmetry finite element model of this structure was developedby using ANSYS code. The results showed that the maximum stress doesnot exceed the allowable value for any of the load combinationsaccording to ASME code and the nine vacuum vessel (VV) supports havethe ability to sustain the entire VV and in vessel-components andwithstand load combinations under both normal as well as off-normaloperation conditions. Stress mainly concentrates on the connectingregion of the VV support and lower port stub extension.
