“…thermal fragmentation, resulting from the destabilization of the vapour film around the melt droplets, and hydrodynamic fragmentation, resulting from the velocity differences between the melt droplets and the surrounding medium, are considered. The diameter of the created fragments, which is a user parameter, was set to the code standard value 100 µm, which is based on KROTOS experiments (Huhtiniemi et al, 1999). The explosion is triggered by applying a user defined initial local pressure pulse.…”

“…In MC3D it is conservatively assumed that the melt droplets are completely molten if their bulk temperature is higher than the corium solidus temperature. This overpredicts the ability of corium droplets to efficiently participate in the explosion, since in reality, during premixing, a crust is formed on the corium droplets before the droplet bulk temperature drops below the solidus temperature (Huhtiniemi et al, 1999;Dinh, 2007). This crust inhibits the fine fragmentation process and if the crust is thick enough it completely prevents it.…”
