On the Present State of Investigation of Thermodynamic Properties of Solid and Liquid UO2+X
The U¿O system has been investigated for almost fifty years, and, in particular, the UO2±x solid-solution
phase boundary was considered as established since the beginning of the 1980s. Nevertheless, the
results of thermodynamic measurements at temperatures above 2500 K performed with traditional
techniques are probably affected by large errors. These are mostly due to reactions of the sample with
the containment and to poor control of the equilibrium vapour pressure, with consequent composition
instabilities.
