## Summary

Nuclear Restoration Services Limited commissioned a specialist safety assessment service for its Dounreay site in Scotland. The requirement was to produce a deterministic fire risk assessment supporting the safety case for a new Prototype Fast Reactor Alkali Metal Store. This is a technical safety-case assignment rather than construction, equipment supply or general fire-risk consultancy. The work falls within safety-case services and is relevant to organisations with expertise in fire hazard analysis, nuclear safety, reactor-related facilities and the preparation of evidence for regulated safety cases. Delivery is associated with Dounreay, at KW14 7TZ, in Scotland. The buyer is Nuclear Restoration Services Limited, whose Dounreay operations are the setting and purpose for the assessment.

The procurement has been awarded and the tender is complete. Nuclear Restoration Services Limited selected Mott MacDonald Ltd through a selective call-off from a framework agreement. The award was made on 10 August 2026 for £42,600 including the stated currency of GBP. The contract period runs from 11 August 2026 to 28 October 2026. The tender submission deadline was 5 August 2026 at 12:00. The requirement was classified as a services procurement and identified as suitable for small and medium-sized enterprises. There were no lots or separate awards. The available process information establishes the framework call-off route; the published procurement data does not set out a separate quality, price or other scoring basis for the selection.

For a supplier assessing future demand from this buyer, the award indicates a focused need for specialist fire-safety analysis that can be incorporated into a nuclear safety case. Credible competitors would need demonstrable capability in deterministic fire risk assessment, fire hazard identification and consequence analysis, together with the ability to produce clear, auditable technical evidence for a safety-case process. Experience of nuclear facilities, reactor projects or comparable high-hazard industrial environments would help establish technical credibility. Suppliers should also be able to work closely with the asset owner and safety-case team, understand the risks associated with alkali-metal storage, and deliver a concise assessment to a demanding technical standard within a defined assignment.
