To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts
seek solid fuels that must withstand unprecedented temperature and radiation extremes. In …

Molecular dynamics simulations have been carried out to investigate the primary radiation
damage in (U 1-y, Pu y) O 2 solid solution for various temperatures and plutonium contents …

This work presents a detailed study of hyperstoichiometric UO2+ x (0< x< 0.25) oxides and
an assessment of the structural evolution taking place as oxidation proceeds. For this …

Plasticity of irradiated UO 2 is of major interest to improve the risk assessment of the nuclear
fuel cladding failure in the case of design basis accidents. In this study, we investigate the …

Ion accelerators have been used by material scientists for decades to investigate radiation
damage formation in nuclear materials and thus to emulate neutron-induced changes. The …

A ceramic sample of uranium dioxide is probed by Raman imaging followed by a combined
Lorentzian fitting–Principal Component Analysis process. This allows to evidence structural …

The early stages of nucleation and growth of dislocations by irradiation in urania is clarified
based on the combination of experiments and atomistic calculations. It is established that …

The early stage of microstructural evolution of ThO2, under krypton irradiation at 600, 800,
and 1000° C, was investigated using in situ transmission electron microscopy (TEM) …

In situ characterization of defects, microstructure, and properties will provide new
perspectives regarding the structure-property relationship of materials in extreme …

This work focuses on the full characterization of dislocation loops induced by proton
irradiation in single-crystal ThO 2. Irradiation was performed using 2 MeV H+ ions with …
