## Summary

Sellafield Ltd procured works for the DNWP0028 Alpha SAS trialling, commissioning and active learning requirement. The work is classified as decommissioning services and relates to activity at the Sellafield site. The title identifies the requirement as Lot 1B, but the published scope provides no further breakdown of the works. This is a specialist nuclear-site decommissioning requirement, rather than a general construction project. The buying organisation is Sellafield Ltd, based in Whitehaven. The procurement concerns delivery at the CA20 1PG site location.

The procurement is complete and was awarded to AtkinsAltrad. The award was made on 23 October 2026, with a value of £5,433,563.28. The contract period runs from 26 October 2026 to 29 June 2028. The route was a selective call-off from a framework agreement. The original submission deadline was 5 October 2026 at 12:00. The procurement was classified as works, and SMEs and voluntary, community and social enterprises were marked as unsuitable. No evaluation basis or award criteria are set out in the published process information. The reported award is for the Alpha SAS trialling, commissioning and active learning requirement.

This award shows that Sellafield buys specialist decommissioning works connected with Alpha SAS trialling, commissioning and active learning through framework call-offs. A future competitor would need to be credible in delivering this specific combination of activities in a Sellafield site environment, with the technical capability and operational capacity to carry out the works. The procurement was marked as unsuitable for SMEs and voluntary, community and social enterprises, indicating that the requirement was positioned for suppliers able to meet its scale and delivery demands. The award identifies AtkinsAltrad as the selected supplier, but the published process information does not establish particular accreditations or experience requirements.
