First this paper describes the design requirements in the FaCT project, especially for the safety design. The results of the EAGLE project are briefly described, and their implication in the safety design/assessment of the SFR investigated in the FaCT Project is shown. In the experiments in the EAGLE project, molten pool of fuel-steel mixture or alumina was successfully formed in the test section and discharged downward through the internal duct structure. These results show that the molten material in the core is discharged due to the pressure in the core shortly after the failure of the internal duct in the early stage of molten material formation and that the discharged material could be quenched as fragmented debris if sufficient amount of coolant is available. This implies that there could be a design solution for the safety design requirements in the FaCT Project.
