Kinetic and thermodynamic studies of the dissolution of thoria-urania solid solutions
TL;DR: In this article, the dissolution of Th 1� xUxO2 was investigated through leaching experiments combined with X-ray photoelectron spectroscopy (XPS) and XAS analyses.
Journal ArticleDOI
Thoria and inert matrix fuels for a sustainable nuclear power
TL;DR: In this paper, inert matrix fuels, possibly containing thoria, were used in a once-through cycle for nuclear power to meet the proliferation risk, and the results showed that these fuels are very well suited for direct disposal in a geological repository.
Journal ArticleDOI
The kinetics of dissolution of Th1−xUxO2 solid solutions in nitric media
TL;DR: In this article, the dissolution of thorium-uranium (IV) dioxide solid solutions has been investigated in nitric media as a function of several parameters (leaching time, acidity of the leachate, temperature and uranium substitution rate in the solid solution) by using batch experiments.
Journal ArticleDOI
Corrosion of UO2 and ThO2: A quantum-mechanical investigation
TL;DR: The addition of Th to U-based fuels increases resistance to corrosion due to differences in redox-chemistry and electronic properties between UO2 and ThO2 as mentioned in this paper.
Journal ArticleDOI
Immobilization of radionuclides in single-phase crystalline waste forms : A review on their intrinsic properties and long term behaviour
TL;DR: In this paper, the authors considered a set of solids considered as potential host matrices for specific immobilization of radionuclides and compared their respective performance in terms of dissolution rate, radiation effects and surface sorption properties.

A kinetic study of the dissolution of uraninite
TL;DR: The kinetics of uraninite dissolution in water may be summarized by the equation: R = (-d(uran)/dt) = 10/sup 20/./sup 25/ (SS) (RF)/sup -1/ (10/sup -3.38-10.8 NOC/) (a/sub..sigma..CO/sub 2//) (D.O.) (a sub H/sup +//) exp (-7045/T) day/sup 1/1/

A new fuel material for once-through weapons plutonium burning
TL;DR: For the burning of plutonium derived from nuclear warheads, once-through type oxide fuels have been studied by considering their proliferation resistance and environmental safety as well as their technological backgrounds of fuel fabrication and reactors.
