## Summary

Nuclear Restoration Services Limited procured an alternative method of bulk nitrogen supplies for the Dounreay site, Phase 2. The requirement is categorised as a service and includes a feasibility-study element (CPV 79314000). It supports activity at the Dounreay nuclear restoration site in Scotland. The buyer is Nuclear Restoration Services Limited, a public authority responsible for the procurement and associated site requirement. The selected supplier, Nuvia Limited, is a large organisation. The scope is focused on bulk nitrogen provision through an alternative supply method rather than a general industrial-gases framework, and is specific to the Dounreay site. Businesses reviewing the opportunity should therefore have a relevant bulk-gas supply or technical feasibility capability applicable to a nuclear-site operating environment.

The procurement has been completed and the contract was awarded to Nuvia Limited under a single lot. The route was a below-threshold limited competition, recorded as a direct-award contract in the tender description. The contract was signed on 13 August 2026 and runs from 13 August 2026 to 4 August 2027. Its gross value is £99,077.34. The contract is active and the award is active. The evaluation basis is not set out in the available process details. The award covers services associated with the alternative bulk nitrogen supply method for Dounreay, including the feasibility-study classification. No separate supplier or lot award is recorded.

This completed procurement demonstrates a defined requirement from Nuclear Restoration Services Limited for an alternative bulk nitrogen supply method at the Dounreay site, with a feasibility-study component and a contract scale below the applicable threshold. It is relevant to businesses that can combine bulk nitrogen supply with technical assessment, feasibility work and practical delivery planning for a specialist site. A credible competitor would need to show that it can maintain reliable supply, understand the operational constraints of a nuclear restoration environment and develop an alternative method rather than simply provide standard gas deliveries. The limited-competition route also indicates that suppliers need to be identifiable, technically credible and able to engage with a focused requirement. Nuvia Limited’s award provides a benchmark for the type of established supplier likely to satisfy this buyer.
