The fast breeder reactor (FBR) uses liquid sodium as a primary coolant, and is characterized by operation at high temperature and under atmospheric pressure. Therefore, the main vessels are essentially required to cope with thermal stresses in their structural design. To reduce such stresses, it is necessary to make the vessel walls as thin as possible. This makes it essential to study the stability of reactor structures against buckling under earthquake loadings. However, it generally takes an enormous amount of computer time to execute dynamic buckling analysis by the finite element method. The purpose of the present paper is to describe the development of an elastic-plastic dynamic buckling analysis code for axisymmetric shells of revolution with high efficiency including fluid-structure interaction.
