Summary of the contracting process

Nuclear Restoration Services Limited procured a modular containment system, known as ModuCon, for contamination control during post-operational clean-out operations at the Harwell site. The requirement is for a temporary enclosure that creates a safe, suitably ventilated radiological work area for removing hazardous materials from storage tubes. The system must be capable of being dismantled and reconstructed in different locations within the site facility. This is a goods procurement covering modular and portable buildings (CPV 44211100). The work is associated with nuclear restoration and decommissioning activities, particularly controlled handling of hazardous and radioactive materials. The named supplier is Nuvia Limited, a large organisation based in Warrington.

The procurement is complete and was awarded to Nuvia Limited through a direct award. The award decision was dated 21 July 2026, with a standstill period ending on 30 July 2026. The contract is scheduled to run from 3 August 2026 to 30 January 2027, with signature due by 3 August 2026. The awarded value is £400,000 gross. The buyer justified the direct award on technical grounds, stating that Nuvia’s ModuCon was the only appropriate product available and that there were no reasonable alternatives. The procedure had one lot, assessed as suitable for SMEs. The award is recorded as pending, although the supplier has been selected.

This procurement indicates demand from Nuclear Restoration Services Limited for specialist, relocatable containment infrastructure used in nuclear decommissioning and hazardous-material removal. A credible future competitor would need to design, supply or integrate temporary enclosures that provide effective contamination control, suitable ventilation and a safe radiological working environment. The ability to dismantle and reconstruct the system at different locations within a nuclear site is central to the requirement. Suppliers would also need evidence that their solution is technically distinct, reliable and capable of meeting demanding site-safety and operational constraints. Relevant experience in nuclear restoration, post-operational clean-out, radiological protection, modular buildings or hazardous-area engineering would strengthen their position when comparable requirements are next considered.
