Title: Thermodynamic assessment of the Pr-O system

Abstract

We found that the Calphad method was used to perform a thermodynamic assessment of the Pr–O system. Compound energy formalism representations were developed for the fluorite α-PrO _2–x and bixbyite σ-Pr ₃ O _{5 ± x} solid solutions while the two-sublattice liquid model was used to describe the binary melt. The series of phases between Pr ₂ O ₃ and PrO ₂ were taken to be stoichiometric. Moreover, the equilibrium oxygen pressure, phase equilibria, and enthalpy data were used to optimize the adjustable parameters of the models for a self-consistent representation of the thermodynamic behavior of the Pr–O system from 298 K to melting.

Thermodynamic assessment of the U–La–O system

Journal Article McMurray, J. W. ; Shin, D. ; Besmann, T. M. - Journal of Nuclear Materials

The CALPHAD methodology was used to develop a thermodynamic assessment of the U-La-O system. The solid solution and liquid phases are described with the compound energy formalism and the partially ionic two-sublattice liquid model respectively. A density functional theory (DFT) calculation for the lattice stability of the fictive lanthanum oxide fluorite structure compound is used to determine the Gibbs energies for the La containing end-members in the CEF model for U_1-yLa_yO_2+x. Experimental thermodynamic and phase equilibria data were then used in optimizations to develop representations of the phases in the system that can be extended to include other actinide andmore »« less

A combined experimental and computational thermodynamic investigation of the U-Th-O system

Journal Article McMurray, Jake Wesley ; Voit, Stewart L. ; Besmann, Theodore M. - Journal of the American Ceramic Society

Here, the thermodynamics of the U–Th–O system have been assessed using the Calphad method. The compound energy formalism (CEF) and a partially ionic two-sublattice liquid model (TSLM) were used for the fluorite U_1–yTh_yO_2±x, γ-(U,Th)₄O₉, and the U–Th–O melt. The O₂ activity of fluorite U_1–yTh_yO_2±x with temperature and composition was determined by thermogravimetric analysis. Thermodynamic studies for the Th–O binary and U–Th–O ternary available in the open literature were critically reviewed. A self-consistent data set was selected and compiled with the equilibrium oxygen pressures determined by thermogravimetry in order to optimize the adjustable parameters of models selected to represent the phasesmore » in the Th–O and U–Th–O systems.« less

Experimental oxygen potentials of U_1-yPr_yO_{2± x} and thermodynamic assessment of the U-Pr-O system

Journal Article McMurray, Jake W. ; Silva, Chinthaka M. - Journal of Nuclear Materials

Thermogravimetric analysis (TGA) was used to determine the oxygen potentials of fluorite urania-praseodymia (U_1-yPr_yO_{2± x}) solid solutions for y = 0.10 and 0.20 between 1000 and 1500 °C. A thermodynamic assessment of U-Pr-O system was performed using the CALPHAD (CALculation of PHAse Diagrams) method. Furthermore, the models well reproduce the TGA measurements and the computed phase relations are in good agreement with those proposed from an X-ray diffraction investigation.

Thermodynamic modeling of the U₃O_8-x solid solution phase

Journal Article Utlak, Stephen A. ; McMurray, Jacob W. - Journal of Nuclear Materials

It is important to accurately characterize the equilibrium behavior of U₃O₈ during UO₂ nuclear fuel fabrication as the determination of the oxygen to uranium ratio in UO₂ powders and pellets is dependent on U₃O₈ stoichiometry. Prior thermodynamic modeling efforts have treated U₃O₈ as stoichiometric; however, it is experimentally known that the phase exhibits hypostoichiometric behavior at temperatures >850 K. The goal of this work was to model U₃O₈ as a solid solution using the compound energy formalism and optimize the model to experimental data according to the CALPHAD methodology. Results of the U₃O_8-x model assessment were visualized by recalculating themore »« less
