This report mainly introduces trends in fast reactor development in Japan in addition to introducing overseas development trends for major developing countries. The paper describes major severe accident study results focusing on kinetics of interaction in core material mixtures, physical properties of core material mixtures, high temperature thermodynamic data for the uranium oxide (UO $_{2}$ )-iron (Fe)-boron carbide (B $_{4}$ C) system, experimental studies on B $_{4}$ C-stainless steel (SS) kinetics and B $_{4}$ C-SS eutectic material relocation (freezing), and B $_{4}$ C-SS eutectic and kinetics models for severe accident code systems,

CEA and JAEA defined new sub-tasks under the current implementing arrangement: Kinetics of interaction in core material mixtures- Physical properties of core material mixtures, High temperature thermodynamic data for the UO $_{2}$ -Fe-B $_{4}$ C system, Experimental studies on B $_{4}$ C-SS kinetics and B $_{4}$ C-SS eutectic material relocation (freezing), B $_{4}$ C/SS eutectic and kinetics models for SIMMER code systems, Methodology for the modelling of mixtures liquefaction kinetics. The paper describes major R&D results obtained in the France-Japan collaboration under the previous implementing arrangement as well as experimental and analytical roadmaps under the current arrangement.
