## Summary

The National Nuclear Laboratory Limited has awarded a contract titled "Particle Detector Radiation Testing" to Amentum Clean Energy Ltd. This procurement falls under the industry category of analysis services, with technical testing services as an additional classification. The project is located in the North West region of the United Kingdom and has reached the award stage. The total contract value is £29,801, covering a period from 14 January 2025 to 31 March 2025. The procurement method was a direct single tender action, below threshold.

This procurement opportunity supports business growth by offering a contract to perform essential radiation exposure testing on muon particle detectors, contributing to important decommissioning activities at Sellafield. It is particularly suitable for small and medium-sized enterprises (SMEs) with expertise in technical testing and analysis services. The collaboration with a university and the involvement in high-stakes research and development projects provide an excellent platform for businesses looking to expand their footprint in the nuclear and technical testing sectors.

## Notice

UKNNL are working with a University to develop and trial a muon particle detector to be used to image shielded boxes during decommissioning activities at Sellafield. Whilst in operation the detector will not be shielded and as such will be exposed to the full radiation field from the waste boxes. As part of the research to determine the detectors suitability, it is necessary to understand the functionality of the electronic detector modules when exposed to radiation. After a successful test at a Co-60 gamma facility, this follow up testing will support further development of the detector.
