Sodalites have been investigated experimentally for the capture and long-term containment of 129I, a significant and hazardous waste product of the nuclear fuel cycle. Sodalites are zeolite-type structures commonly occurring in nature in alkaline ign

A candidate Ni Mo Cr Fe alloy (GH3535) for application as a structural material in a molten salt nuclear reactor was irradiated with 1 MeV Kr2+ ions (723 K, max dose of 100 dpa) at the IVEM-Tandem facility. The evolution of defects like dislocation l

This ion-irradiation study covers the four major crystal structure types in the Ln 2 TiO 5 series (Ln = lanthanide), namely orthorhombic Pnma , hexagonal P6 3 /mmc , cubic (pyrochlore-like) Fd-3m and cubic (fluorite-like) Fm-3m . This is the first sy

The crystalline and amorphous structures of U3Si have been investigated using density functional theory techniques for the first time. The effects of disorder and the impact of fission products has been separated to understand the swelling characteri

Systematic molecular dynamics simulations of low energy cascades have been performed to examine how threshold displacement events are effected by changes in crystal structure. Exploiting the structural proximity of the rutile, anatase and brookite po

Atomic scale modelling suggests that excess oxygen can be accommodated in the group II perovskite zirconates by the formation of peroxide ion defects. This is unprecedented given the lack of charge compensating defects required for standard excess ox

Accommodation of excess oxygen in CeO 2 , ThO 2 and UO 2 has been investigated using ab-initio modelling. Calculations indicate that hyperstoichiometry is preferentially accommodated by the formation of peroxide species in CeO 2 and ThO 2 but not in
