Abstract

This report reviews the methods for predicting the response of structures at high temperature with particular reference to the steel structures of PWRs and LMFBRs. The fundamental aspects of these methods are equilibrium, strain/displacement relationships and material constitutive laws. Of particular interest here is the effect of temperature on time dependent deformation under stress (creep) and on time independent plastic deformation (yielding). The analysis methods available fall into three categories, viz empirical, analytical and numerical. The structural materials in LMFBRs and PWRs are mainly austenitic stainless steels and low alloy ferritic steels. Data for these are gathered in their generic forms and parameters derived for use in simple constitutive laws.
