Theoretical evaluation of thermal conductivity and its application of BaUO3

Abstract

In this work, an efficiently analytical expression has presented to calculate for the thermal conductivity using Debye function. Note that, the Debye function can be applied to calculate some of the thermodynamic properties of matter and fluids. It has been demonstrated that this formula gives very correct results thermal conductivity of nuclear fuel for a wide range of temperature. The results for thermal conductivity of BaUO3 materials have been compared with theoretical calculations and experimental data and shown that the analytical formula can be satisfactorily used for other nuclear fuel materials.
