The European Fast Reactor (EFR) collaboration with the EFR Associates Design and Construction Rules Committee, and the R&D Agreement (AGT9B) produced significant developments in design-by-analysis procedures for high temperature plant. Many of these developments are judged to be relevant to the non-creep conditions of LWR plant, and for this reason, the CEC DGXI Working Group Codes and Standards supported this study to review and make recommendations on their potential application for improving LWR design code procedures. The topics considered are judged to be those where the most significant and relevant developments have been made and the list, although not exhaustive, is as follows:
- Negligible creep criteria
- Design-by-analysis procedures for weldments
- Shakedown design rules
- Design-by-analysis methods for tubeplates
- Buckling rules
- Interaction diagrams for assessing ratcheting
- Rules for the prevention of elastic follow-up in piping
- Strain range enhancement
- Constitutive equations for inelastic analysis
- Margins on Level D criteria
- Zarka's method
