Journal ArticleDOI
Comparison of interatomic potentials for UO2. Part I: Static calculations
TL;DR: In this paper, the authors assess the range of applicability of the available interatomic potentials for UO 2 by static calculations, together with defect properties: the formation and activation energies of vacancies and interstitials, the binding energy of small clusters of these defects and the volume change associated with them.
Journal ArticleDOI
Post-irradiation examination of uranium–7 wt% molybdenum atomized dispersion fuel
Ann Leenaers,S. Van den Berghe,E. Koonen,C. Jarousse,F. Huet,M. Trotabas,M. Boyard,S. Guillot,L. Sannen,Marc Verwerft +9 more
TL;DR: In this article, two low-enriched uranium fuel plates consisting of U-7wt%Mo atomized powder dispersed in an aluminum matrix, have been irradiated in the FUTURE irradiation rig of the BR2 reactor at SCK•CEN.
Journal ArticleDOI
Comparison of interatomic potentials for UO2. Part II: Molecular dynamics simulations
TL;DR: In this article, the authors used semi-empirical potentials to simulate the temperature evolution of different elastic properties (lattice parameter, specific heat, bulk modulus and Gruneisen parameter) and by calculations of bulk melting temperature.
Journal ArticleDOI
Accurate lattice parameter measurements of stoichiometric uranium dioxide
TL;DR: In this article, the lattice parameter of pure stoichiometric UO2 was evaluated as being 547.127 ± 0.008 pm at 20°C, which is substantially higher than many published values for the UO 2 lattice constant and has an improved precision by about one order of magnitude.
Journal ArticleDOI
Evolution of the Uranium Chemical State in Mixed-Valence Oxides.
Gregory Leinders,René Bes,Janne Pakarinen,Kristina O. Kvashnina,Kristina O. Kvashnina,Marc Verwerft +5 more
TL;DR: High energy resolution fluorescence detection X-ray absorption near edge spectroscopy at the uranium M4 edge is used, and a pivot from U(IV)-U(V) to U(V-U(VI) charge compensation is identified, corresponding with transition from a fluorite-type structure (U3O7) to a layered structure ( U3O8).
