Summary of the contracting process

Sellafield Ltd procured works for the DNWP0070/Lot1B SEMAS Optioneering Study. The requirement is classified as decommissioning services and concerns a study to assess and compare options for the SEMAS workstream. It sits within the wider decommissioning activity at Sellafield and is intended to support decisions about how that work should be delivered. The main procurement category is works, although the core activity is specialist technical and analytical study work. Delivery is in North West England, within the area covered by postcode CA20 1PG. The named buying organisation is Sellafield Ltd, the company responsible for the Sellafield site and its associated decommissioning programme.

The procurement is complete and has been awarded. Sellafield Ltd used a selective procedure as a call-off from a framework agreement. The contract was awarded to AtkinsAltrad on 17 July 2026 for £338,328.59 including the stated GBP currency. The contract period runs from 20 July 2026 to 30 November 2026. The tender submission deadline was 19 May 2026 at 4pm. This was a single requirement identified as Lot 1B, with the award recorded as active. The procurement was not identified as suitable for small or medium-sized enterprises or voluntary, community and social enterprises. The available evaluation information indicates the award was made through the framework call-off route.

This award shows demand from Sellafield for specialist decommissioning optioneering and technical study capability. A credible future competitor would need to understand nuclear decommissioning environments, develop and compare practicable delivery options, and present clear analysis that can support major asset or programme decisions. Framework access is commercially important because this requirement was placed as a framework call-off rather than as an open competition. Suppliers should therefore be able to demonstrate relevant experience, robust technical assurance, suitably qualified personnel and the organisational capacity to deliver a focused study for a major site operator. The stated suitability position indicates that the buyer was targeting established specialist providers rather than small or voluntary-sector organisations.
