In the design of FBR (fast breeder reactor) components, a simple and conservative design can be done by the conventional design method based on elastic analyses. However, there is a possibility that the conservativeness becomes excessive. Therefore, we developed inelastic analysis methods and proposed design guidelines based on the developed inelastic analysis methods. In order to validate the design guidelines, we adapted them to accumulated strain evaluation of a reactor vessel near liquid surface and compared the analysis results by recommended constitutive models with those by the conventional method and discussed the results from the points of view of the description of phenomena and the merits of design.
