Nuclear Stewardship

We believe that nuclear power is an essential part of the energy mix, providing the world with low carbon, reliable electricity. A vital element of the nuclear fuel supply chain is the responsible management and stewardship of nuclear materials, an area in which Urenco plays a trusted role.

Our services

A key part of our commitment to the responsible handling of nuclear materials is overseen by our two wholly-owned subsidiaries; Urenco Nuclear Stewardship (UNS) and Urenco Chemplants (UCP).

Urenco ChemPlants

Urenco ChemPlants (UCP) is a wholly-owned subsidiary based at our Capenhurst site, which is responsible for managing the byproduct that is produced during the enrichment process, known as tails.

The responsible management of tails is crucial to Urenco's commitment to sustainability, which is why we constructed our Tails Management Facility (TMF) that began operations in 2021. The TMF converts tails into a more stable form that allows for long term storage prior to either further enrichment or safe disposal.

Urenco Nuclear Stewardship

Also based at our Capenhurst site, Urenco Nuclear Stewardship (UNS) is a wholly-owned subsidiary of Urenco that has a leading role in waste management, long term storage and decommissioning services.

Our workforce is experienced in providing end-of-lifecycle management solutions for the nuclear industry, including decommissioning and land remediation, waste management and waste services and storage of radiological materials.

Environmental responsibility


We are fully committed to the responsible environmental management of our activities.

We regularly monitor water supplies, air quality and energy emissions (CO2 and direct/indirect energy), as well as carry out environmental impact assessments of all activities. Our activities are also subject to scrutiny by the Office for Nuclear Regulation and the Environment Agency.
