Abstract
During fuel irradiation tests of material and fuel rods, all parts of cylindrical shells with
multiple holes act as heat sources due to fission heat and γ-flux. The thermal stress is induced by a
temperature difference among the heat sources. In this study, the thermal stress of the cylindrical
structure is minimized by using an optimization method about the geometric variables. The circular
shapes of the multi-specimens are investigated. For the thermal analysis of the structure, the finite
element method code, ANSYS 8.1 is used. A sub-problem approximation method is used for the
structural design optimization.
