## Summary

Sellafield Limited, a body governed by public law, has completed the award stage in a procurement process focusing on the maintenance of radiometric hardware and software systems. The tender, titled "Maintenance of Radiometric Hardware and Software Systems and Associated Services," falls under the services category specified by the CPV code 50410000, which relates to the repair and maintenance services of measuring, testing, and checking apparatus. The procurement process was conducted through a limited procedure without prior publication due to technical reasons and exclusive intellectual property rights held by the supplier, Curtiss-Wright Wimborne Limited. Located in Warrington, UK (region UKD1), Sellafield Limited signed the contract on 6th October 2025, valued at £3,298,617.42.

This tender represents a significant opportunity for businesses specialising in highly technical maintenance services, particularly within the radiometric and environmental monitoring sectors. Companies possessing specialised knowledge in maintaining proprietary hardware and software systems with the capacity to deliver offsite and onsite repair, as well as technical support and training services, would be ideal candidates. Large businesses with capabilities to address intellectual property constraints and provide unique technical solutions will find this to be a compelling opportunity to solidify partnerships and grow their business in the niche field of nuclear decommissioning and safety assurance.
