Summary of the contracting process

Nuclear Waste Services Limited is currently in the tender stage of its procurement process for the Treatment & Conditioning Services Framework, covering the period from 2026 to 2030. This procurement is conducted under an open procedure and involves radioactive waste treatment services, including incineration, supercompaction, and chemical treatment. Located in the UK region of Calderbridge, Seascale, the buying organisation is a public authority within the sub-central government. The tender period closes on 20th October 2025, with an award period ending by 1st June 2026. Interested parties must submit their tenders electronically via the Atamis portal.

This framework presents significant business growth opportunities, particularly for companies skilled in waste management, specifically those with expertise in radioactive waste treatment and handling. The procurement is open to suppliers capable of providing comprehensive waste lifecycle management, encouraging involvement from small to medium enterprises that have specialised services in radioactive materials handling and disposal. An anticipated maximum of five suppliers will be selected, which means substantial competition for businesses looking to secure a role in the framework. The open procedure ensures a fair and transparent bidding process, potentially enhancing market access for innovative solutions within the sector.
