Abstract

In this study, we have proposed an analytical method for calculating the specific heat capacity of uranium nitride nuclear material. The specific heat capacity results have obtained by the use of the Debye-Einstein approximation. The thermal conductivity of nuclear material has been obtained by using the experimental data of thermal diffusivity and the calculation results of specific heat capacity. This method shows that our results are satisfactory for the wide range temperature variations. The proposed approach can be easily applied to determine the thermodynamic properties of the other nuclear materials.

Abstract

In dieser Studie wird eine analytische Methode zur Berechnung der spezifischen Wärmekapazität Uran-Nitrid, das als Brennstoff in Kernreaktoren Verwendung findet, vorgeschlagen. Die Ergebnisse der spezifischen Wärmekapazität werden dabei durch die Verwendung der Debye-Einstein-Näherung erzielt. Die Wärmeleitfähigkeit des Kernmaterials wurde durch Verwendung der experimentellen Daten der Wärmeleitfähigkeit und der Berechnungsergebnisse der spezifischen Wärmekapazität ermittelt. Diese Methode zeigt, dass unsere Ergebnisse für einen weiten Bereich von Temperaturschwankungen zufriedenstellend sind. Der vorgeschlagene Ansatz lässt sich leicht auf die Bestimmung der thermodynamischen Eigenschaften anderer Brennstoffmaterialien anwenden.
