## Summary

Nuclear Restoration Services Limited (Dounreay) procured technical support for waste characterisation at the Dounreay site in Thurso, Scotland. The work supports the assessment and characterisation of waste arising at the nuclear site. This is a specialist nuclear-site services requirement, rather than general waste collection or disposal. The procurement was carried out through the Technical & Professional Support Services Framework, with the requirement competed among framework suppliers.

The procurement is complete and has been awarded following a mini-competition under a framework agreement. Eleven contracts were awarded to four suppliers: Cavendish Nuclear, AtkinsRéalis UK Limited, DBD Limited and Amentum Clean Energy Limited. The reported award value is £3,048,000. The contract period runs from 14 September 2026 to 31 August 2028, and the award date is 14 September 2026. The estimated procurement range was £3,048,000 to £3,050,000. The tender submission deadline was 6 July 2026. The procurement used a selective process; evaluation criteria are not stated in the available process details.

The awards show that Dounreay’s waste-characterisation requirement was divided across multiple contracts and placed through competition within a technical and professional support framework. Suppliers competing for comparable work would need relevant capability in characterising waste at a nuclear site, along with the technical expertise and operational capacity to deliver specialist support across a multi-contract requirement. The selected suppliers—Cavendish Nuclear, AtkinsRéalis, DBD and Amentum Clean Energy—indicate the type of established technical and nuclear-sector providers that secured this work. The opportunity was marked as unsuitable for SMEs and voluntary, community and social enterprises, pointing to a requirement aimed at larger, specialist suppliers.
