【 摘 要 】

Available open literature on thermophysical properties of both MOX and UO{sub 2} fuels has been reviewed, and the best set of thermal properties has been selected. The properties reviewed are solidus and liquidus temperatures of the uranium-plutonium dioxide system (melting temperature), thermal expansion, density, heat of fusion, enthalpy, specific heat, and thermal conductivity. Only fuel properties are studied in this report. The selected properties are used in thermal-hydraulic codes to study design basis accidents. The majority of the properties presented are for solid fuel.
