The lower cryopump ports in International Thermonuclear Experimental Reactor (ITER) as a part of the vacuum vessel play many important roles. As the boundary of vacuum it must be ensured against structural damage. In this study a finite element model of the lower cryopump ports was developed by ANSYS code with a purpose to evaluate the stress and displacement level on it. Two kinds of loads were taken into account. One was the hydrostatic pressure including the normal operation pressure and test pressure. The other was the seismic load. The analysis results show that the peak stress does not exceed the allowable stress for either the hydrostatic pressure or the seismic load according to the ITER structural design criterion, which indicates that the structure has a good safety margin.

“…The mechanical strength of the upper port plug must be evaluated for the expected EM loads, especially for an upward fast VDE, which will produce the largest expected load on the upper port plug [6]. Here, EM loads and moments using a three-dimensional (3D) model have been evaluated for the support flange, which is a key point in the cantilevered structure.…”

A structural analysis of the International Thermonuclear Experimental Reactor (ITER) vacuum vessel's lower port region was presented by means of a finite element analysis method. The purpose is to evaluate the stress and displacement level on this structure under various combinations of five designed loads, including the gravity of the vacuum vessel, seismic loads, electromagnetic loads, and possible pressure loads to ensure structural safety. The cyclic symmetry finite element model of this structure was developed by using ANSYS code. The results showed that the maximum stress does not exceed the allowable value for any of the load combinations according to ASME code and the nine vacuum vessel (VV) supports have the ability to sustain the entire VV and in vessel-components and withstand load combinations under both normal as well as off-normal operation conditions. Stress mainly concentrates on the connecting region of the VV support and lower port stub extension.
