Thermophysical properties of mixed oxide fuel and stainless steel type 316 for use in transition phase analysis

For use in transition phase analysis, we have obtained thermodynamic and transport properties of mixed oxide fuel and stainless steel type 316, over a very wide range of temperatures. The majority of the thermodynamic properties for these materials in their solid and liquid states are based on either actual experimental data or extrapolation of low temperature data. However, a number of properties for these materials in the vapor state are based on very limited and scarce data. These properties include saturation vapor pressure, latent heat of vaporization and specific volume of saturated vapor. Due to complete lack of experimental data, a number of other properties such as specific heats, heat of vaporization (especially for stainless steel), transport properties, and the properties at the critical state had to be estimated by use of generally reliable empirical relations. It is recommended that efforts be initiated to obtain experimental data for these materials in the vapor state to verify both existing empirical relations and the relationships that are obtained here based on theoretical analyses.
