Influence of the U3O7 domain structure on cracking during the oxidation of UO2
Lionel Desgranges, Hervé Palancher, M. Gamaléri +5
Cracking is observed when a UO_{2} single crystal is oxidised in air. Previous studies led to the hypothesis that cracking occurs once a critical depth of U_{3}O_{7} oxidised layer…
Pre-Stressed Sub-Surface Contribution on Bulk Diffusion in Metallic Solids
Laura Raceanu, Virgil Optasanu, Tony Montesin +1
Our recent modelling works and corresponding numerical simulations realized to describe the UO2 oxidation processes confirm the theory showing that an applied mechanical strain can…
Internal Interface Strains Effects on UO2/U3O7 Oxidation Behaviour
Nicolas Creton, Virgil Optasanu, Sébastien Garruchet +4
The growth of a U3O7 oxide layer during the anionic oxidation of UO2 pellets induced very important mechanical stresses due to the crystallographic lattice parameters differences b…
Theoretical Study of Coupling Mechanisms between Oxygen Diffusion, Chemical Reaction, Mechanical Stresses in a Solid-Gas Reactive System
Nicolas Creton, Virgil Optasanu, Tony Montesin +1
This paper offers a study of oxygen dissolution into a solid, and its consequences on the mechanical behaviour of the material. In fact, mechanical strains strongly influence the o…
A thermodynamic approach of the mechano-chemical coupling during the oxidation of uranium dioxide
Nicolas Creton, Virgil Optasanu, Tony Montesin +2
The aim of the present work is to introduce a thermodynamic model to describe the growth of an oxide layer on a metallic substrate. More precisely, this paper offers a study of oxy…
