摘要

Since thermal striping is a coupled thermohydraulic and thermomechanical phenomenon, sodium mock-up tests were usually required to confirm structural integrity against it. France and Japan have developed evaluation procedures of thermal striping to establish design-by-analysis methodology for this phenomenon. In order to compare ideas and to validate these methods, two benchmark problems were planned under the framework of CEA/JNC cooperation in fast reactor technologies. One of benchmarks provided by CEA is temperature and fatigue evaluation of tubes and plates tests performed with the FAENA facility. Another problem from JNC is the same evaluation of plate tests conducted by the TIFFSS facility. This report describes the results of inter comparison of temperature and fatigue strength evaluation methods through application to both FAENA and TIFFSS experiments.
