In order to eliminate the energetic potential in the case of postulated core-disruptive accidents (CDAs) of sodium-cooled fast reactors, introduction of a fuel subassembly with an inner-duct structure (FAIDUS) has been proposed. In the present study, to demonstrate a function for early fuel discharge, analytical study using three-dimensional particle-based simulations were performed against a series of multi-component, multi-phase thermal hydraulics phenomena, which are formation of molten pool of fuel and steel mixture caused by disruption of fuel pins, and, heat-transfer from the pool to duct wall.
