## Summary

Sellafield Limited purchased 150 area-mark criticality lockets, described as dosimeters for monitoring radiation exposure. This is a goods requirement supplied for delivery in the United Kingdom. The buyer is Sellafield Limited, a public authority based in Warrington. The requirement is focused on the supply of specialist radiation-monitoring equipment rather than a service, installation project or wider equipment programme. Businesses with relevant dosimeter or criticality-monitoring product lines are the closest fit. The procurement concerns one defined requirement and one lot, covering the stated quantity of 150 lockets.

The procurement is complete and has been awarded. Sellafield Limited used a direct award below the relevant threshold, without competition. Nuvia Ltd was selected as supplier on 18 September 2026, and the contract was signed on the same date. The contract runs from 21 September 2026 to 28 January 2027. Its value is £69,750 excluding VAT, or £83,700 including VAT. The contract is active. The award covers the single requirement for criticality lockets and is classified under CPV 38527200, dosimeters. The published outcome identifies one supplier and does not set out a competitive scoring or evaluation basis.

This procurement indicates demand from Sellafield Limited for a defined batch of specialist radiation-monitoring equipment. A credible future supplier would need products suitable for criticality monitoring and area marking, with the technical assurance, product documentation and supply controls expected for equipment used in a safety-sensitive public-sector environment. Capacity to provide 150 units within a short delivery window would be relevant, as would reliable UK distribution and the ability to meet precise specification requirements. The awarded supplier, Nuvia Ltd, is a large specialist business, so competitors should be prepared to demonstrate comparable technical competence, quality management, regulatory understanding and dependable fulfilment for Sellafield’s operational requirements.
