DISTINCTIVE is a multi-disciplinary collaboration of 10 universities and 3 key industry partners from across the UK’s civil nuclear sector.
PhD/PDRA – PDRA
Academic Leads – Tom Scott and Ross Springell
Researchers: James Darnbrough and Leila Costelle
University – University of Bristol
The project will investigate the physiochemical changes occurring in SNF fuels – specifically uranium metals and exotics – during recovery from aqueous storage, forced drying and repackaging in an ‘open’ but nominally dry engineered containment system.

We will work on non-irradiated U metal and UC samples, corroded under different aqueous conditions using the specialist gas-rig capability in Bristol. We will investigate the physiochemical changes occurring in the corroded materials during drying (over different temperatures) to evaluate transformative reactions occurring at the material surface. Specifically we will seek to understand the developing reactivity and fate of both uranium dioxide and uranium hydride present within the corrosion product.
