Inelastic analysis methods are expected to realize rational design of FBR (fast breeder reactor) components. Development of constitutive models which enable appropriate prediction for inelastic behaviors of structures which are subjected to mechanical and thermal loads has been promoted, and the preparation of the guidelines for inelastic design analysis is underway. Requirements for constitutive models as well as related verification and validation problems are specified in the guidelines. The results of application of the constitutive models for 316FR stainless steel to these problems are briefly described in this paper.
