Themes

DISTINCTIVE is a multi-disciplinary collaboration of 10 universities and 3 key industry partners from across the UK’s civil nuclear sector.

AGR, Magnox and Exotic Spent Fuels
AGR, Magnox and Exotic Spent Fuels

This theme addresses the UK’s spent nuclear fuel inventory, and the preferred options for disposal.  This includes the retrieval of fuel from current storage facilities and the repackaging options available. The theme is concerned with Advanced Gas-Cooled Reactor (AGR), Magnox and other so-called ‘Exotic’ spent fuels, and its goal is to increase knowledge and mechanistic understanding of the processes involved during management.

PuO2 and Fuel Residues
PuO2 and Fuel Residues

This theme addresses the challenge presented by the UK’s civil plutonium inventory.  Plutonium is a bi-product of reprocessing spent fuel received from the UK’s fleet of nuclear power generators, and there are approximately 125 tonnes of Pu in interim storage in the UK.  However, no decision has yet to be made regarding its final treatment and disposition.

Legacy Ponds and Silo Wastes
Legacy Ponds and Silo Wastes

This theme addresses the clean-up of the UK’s biggest safety and security threat; the Sellafield legacy ponds and silos (LP&S).  The LP&S care and maintenance programme currently costs the UK tax payer approximately £70 million per yearto maintain their basic condition.

Structural Integrity
Structural Integrity

This theme addresses the challenge of ageing nuclear infrastructure, and how to ensure the continued safety of the workforce involved in nuclear decommissioning and management. The aim is to develop reliable systems for nuclear infrastructure characterisation, restoration and preservation.
