## Summary

Sellafield Limited, a public body governed by public law and specialising in nuclear decommissioning, has completed a procurement process for the maintenance of radiometric hardware and software systems. This tender falls under the services industry category, specifically for repair and maintenance services of measuring, testing, and checking apparatus. Located in the UKD1 region, the contract, valued at £2,966,916, was signed on 2nd October 2025. The procurement method was limited, conducted without prior publication of a call for competition due to technical reasons and the protection of intellectual property rights held by the supplier. The process has now reached the 'award' stage, with the contract awarded to Mirion Technologies (Canberra UK) Ltd.

This tender presents significant opportunities for businesses involved in radiometric technology or those equipped to handle the maintenance and repair of such specialist equipment. Companies with expertise in environmental monitoring and the ability to provide technical support in managing aging and obsolescence of systems are well-suited to compete for similar contracts. Furthermore, businesses possessing intellectual property rights for their technology may find opportunities in similar sole-source procurements, where competition is limited due to specialised technical requirements. This contract highlights the potential for sustained business growth within the niche market of radiometric protection instruments and associated services.

## Notice

- Offsite and onsite repair, maintenance and overhaul of radiometric and environmental monitoring/sampling systems and other specialist equipment, including Lab-Impex and Berthold products and systems. This equipment is typically used at Sellafield for the measurement and quantification of radiation and contamination (including environmental, stack and building ventilation systems). 

- This scope covers, but is not limited to, technical support, aging and obsolescence (A&O) support, and the provision of associated services, including training.

The supplier retains the intellectual property rights (IPR), including copyright and patents, for the Radiometric Protection Instruments being maintained as part of this contract.
