Inelastic analysis methods are expected to realize rational design of FBR (fast breeder reactor) components. Constitutive models play a key role in jedicting inelastic behaviors of structures which are subjected to mechanical and thennal loads. Development of constitutive models which enable precise but certainly conservative prediction has been promoted, and guidelines for inelastic design analysis were proposed. The constitutive models currently recommended for the FBR-grade type 316 stainless steel (316FR) in the guidelines are outlined in this paper.
