Keywords:MOX, Physical Property, Heat capacity, Thermal conductivity

The model which evaluates the specific heat and a thermal conductivities of MOX fuels was derived using sound speeds, lattice parameter, thermal expansion and oxygen potential. The model named Science-based Integrated Models for MOX Properties (ScIM for MOXProp) can describe various physical property data as functions of temperature, Pu content, MA content and O/M ratio. The model will be applied to a fuel performance code seamlessly as parameters of fuel compositions.
