TL;DR: In this paper, it is shown that uncertainty bands related to oxygen behavior in the equilibria between condensed phases and gas should not significantly affect the qualitative trend of the current solid-liquid phase boundaries.

DFT+U study of the structures and properties of the actinide dioxides
James T. Pegg,James T. Pegg,Xavier Aparicio-Anglès,Mark T. Storr,Nora H. de Leeuw,Nora H. de Leeuw +5 more
TL;DR: In this paper, the most suitable Coulombic (U) and exchange (J) parameters for different functionals were parametrized within the DFT+U formulism to reproduce the experimental band-gap and lattice parameters for actinide oxides.

Coupled thermochemical, isotopic evolution and heat transfer simulations in highly irradiated UO2 nuclear fuel
Markus H.A. Piro,James E Banfield,Kevin T. Clarno,Srdjan Simunovic,Theodore M. Besmann,Brent J. Lewis,W.T. Thompson +6 more
TL;DR: In this paper, the authors used thermochemical, isotopic and heat transfer models to predict the departure from stoichiometry of UO 2, but also considered dissolved fission and activation products in the fluorite oxide phase, noble metal inclusions, secondary oxides including uranates, zirconates, molybdates and the gas phase.
Volume interdiffusion coefficient and uncertainty assessment for polycrystalline materials
TL;DR: In this paper, uncertainties on the interdiff usion coefficient as a function of concentration have been computed for each method, and small volume coeffi cient measurements were enhanced by means of a small angle acquisition pro le line with respect to the interface.

SGTE data for pure elements
TL;DR: In this article, the authors present the data for the condensed phases of 78 elements as currently used by SGTE (Scientific Group Thermodata Europe) as a sound basis for the critical assessment of thermodynamic data, thereby, perhaps, limiting unnecessary duplication of effort.

The Thermo-Calc databank system☆
TL;DR: Using the facilities of Thermo-Calc one can tabulate thermodynamic data, calculate the heat change of chemical reactions and their driving force, evaluate equilibria for chemical systems and phase transformations and calculate various types of multicomponent phase diagrams by an automatic mapping procedure.

A regular solution model for phases with several components and sublattices, suitable for computer applications
Bo Sundman,John Ågren +1 more
TL;DR: In this paper, a thermodynamic model based on the regular solution approximation is presented and a formalism, suitable for phases with an arbitrary number of sublattices, is developed, in order to simplify the analytical expressions for the integral Gibbs energy.
