The Cavendish Dounreay Partnership (CDP) has successfully removed 700kg of highly enriched uranium (HEU) from Dounreay in Northern Scotland. The CDP is a consortium of Cavendish Nuclear, Jacobs and AECOM that owns that Dounreay site under contract from the UK Nuclear Decommissioning Authority (NDA).

CDP in partnership with the US Department of Energy’s National Nuclear Security Administration (NNSA) transferred the HEU to the US. The HEU from the site will be down-blended in the US as fuel for civil nuclear reactors. The US will send a different form of HEU to Europe, which will be used as research reactor fuel and in the production of medical isotopes. The transfer of the HEU honours the UK government’s commitment to the 2016 Nuclear Security Summit.

CDP chairman Simon Bowen said: “Delivery of this strategically-important project in the decommissioning of the Dounreay site is testament to the hard work of the Dounreay team and the collaborative approach taken by them, the supply chain and the other organisations involved, who have all helped make this a success.”

NDA CEO David Peattie added: “The successful completion of the complex work to transfer HEU is an important milestone in the programme to decommission and clean up Dounreay Site.”

US Department of Energy under-secretary for nuclear security Lisa Gordon-Hagerty said: “This joint effort highlights our strong cooperation and mutual non-proliferation goals.”

The removal is part of an ongoing programme to remove HEU from the site.
