Reduced activation ferritic martensitic (RAFM) and oxide dispersion strengthened (ODS)
steels are the most promising candidates for fusion first-wall/blanket (FW/B) structures. The …

Prediction of material performance in fusion reactor environments relies on computational
modelling, and will continue to do so until the first generation of fusion power plants come on …

How displacement damage defects generate and evolve in materials irradiated by energetic
particles is a perennial topic in the field of nuclear materials. Here we experimentally reveal …
