Keywords:Fuel debris, Laser heating, Molecular dynamics simulation, Melting point

Melting points of CeO2-ZrO2-FeO1+xmixtures were evaluated by the containerless method with laser heating, and their thermal conductivities and heat capacities were measured as well. Meanwhile, using the molecular dynamics technique, melting behaviors of UO2(or CeO2)-ZrO2-FeO1+xmixtures were evaluated.
