Thermophysical properties of uranium dioxide

Abstract The thermophysical properties of uranium dioxide from room temperature to 6000 K are reviewed. Properties discussed include: enthalpy, heat capacity, vapor pressure, density, thermal expansion, compressibility, thermal conductivity, viscosity, and emissivity. Estimates of the reliability of the recommended values are given; needs for further experiments are pointed out.
