A method for phenomenological and chemical kinetics study of autocatalytic reactive dissolution by optical microscopy. The case of uranium dioxide dissolution in nitric acid media

EPJ Nuclear Sciences & Technologies, 2018
Dissolution is a milestone of the head-end of hydrometallurgical processes, as the stabilization rates of the chemical elements determine the process performance and hold-up.

PRELIMINARY REPORT ON CONVERSION OF URANIUM HEXAFLUORIDE TO URANIUM DIOXIDE IN A ONE-STEP FLUID-BED PROCESS

, 1959
A one-step, continuous, fluid-bed process for the conversion of uranium hexafluoride to uranium dioxide was successfully carried out in preliminary experiments in a 1 1/2-inch-diameter Monel reactor.

Determination of U3O8 in UO2 by infrared spectroscopy

REM: International Engineering Journal
The oxygen-uranium (O-U) system has various oxides, such as UO2, U4O9, U3O8, and UO3. Uranium dioxide is the most important one because it is used as nuclear fuel in nuclear power plants.

Effects of stoichiometry on the defect clustering in uranium dioxide

, 2015
This study addresses the on-going topic of point defects and point defect clusters in uranium dioxide. Molecular statics simulation using an extended pair potential model that accounts for disproportionation equilibrium as charge compensation has been ...

First-Principles Investigation: Effects of Molybdenum Substitution on the Elastic Properties of Uranium Dioxide

Crystals
Uranium dioxide (UO2) is the standard fuel in light water reactors, but improving its mechanical performance is essential for achieving higher burnups. This study employs first-principles density functional theory with the DFT + U approach to investigate
