UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Nuclear Restoration Services Limited is considering a future Delivery Partner procurement for decommissioning the legacy Shaft and Silo intermediate-level radioactive waste storage facilities at the Dounreay Site in Caithness, Scotland. The requirement is classified as works and covers engineering and construction works associated with dismantling, managing and restoring these nuclear storage facilities. The work would support the wider decommissioning of the Dounreay site and would be delivered on the site in Caithness. It is intended for organisations able to operate in a nuclear decommissioning environment and deliver complex engineering and construction activities. The buyer is Nuclear Restoration Services Limited, a public authority responsible for nuclear restoration activities.

This procurement is at the planning stage: NRS is conducting preliminary market engagement for a potential future contract, rather than inviting tenders. The anticipated procurement is a single planned lot, with an estimated gross value of £40,000,000. The expected contract period is 15 February 2027 to 14 February 2037. NRS indicates that the next notice is expected on 1 January 2027, and a supplier webinar was planned for 13 May 2026 to provide high-level information about the programme and potential Delivery Partner role. The procurement is above the applicable threshold and is expected to involve a framework agreement. The market engagement is being conducted under the Procurement Act 2023.

This will suit established nuclear decommissioning contractors, engineering businesses and construction organisations able to work as, or alongside, a Delivery Partner on a technically complex radioactive-waste storage decommissioning programme. Relevant preparation should focus on demonstrating capability in nuclear-site delivery, engineering and construction, decommissioning legacy facilities, and managing work over a long operating period. Suppliers should be ready to explain how they would plan and control complex works, maintain safe operations and coordinate delivery at the Dounreay site. Businesses without nuclear experience may be relevant where they can provide specialist engineering or construction capacity through a credible delivery model. The early engagement provides an opportunity to understand the programme and potential role before the future procurement is developed.
