## Summary

The public procurement process conducted by the UK Atomic Energy Authority (UKAEA) involved the supply, installation, and commissioning of Liquid Scintillation Counters. Situated at the Culham Science Centre in Oxfordshire, UKAEA's procurement falls under the industry category of nuclear evaluation instruments. The contracting process followed an open procedure and has been completed, with the award dated 31st March 2026. The awarded supplier is Revvity (UK) Ltd., located in Pontyclun, United Kingdom. The procurement was aimed at upgrading the analytical capabilities at the UKAEA Health Physics Laboratory by replacing end-of-life equipment. The contract, valued at £263,457.12 gross, spans from 16th April 2026 until 31st December 2027.

This tender provides significant opportunities for businesses involved in nuclear evaluation instruments, particularly those with expertise in supplying high-quality, technical laboratory equipment. SMEs, like the awarded supplier Revvity (UK) Ltd., which focus on delivering innovative solutions in nuclear, biological, chemical, and radiological protection, could substantially benefit. With a strong emphasis on maintaining the UK's analytical capabilities in processing tritium samples, businesses offering tailored and advanced technological solutions will find this procurement an attractive platform for business growth and showcasing expertise in delivering critical equipment to central government authorities like UKAEA.

## Notice

The UKAEA Health Physics Laboratory provides analysis of tritium contaminated smears, air samples and liquids from facilities across the Culham site. In addition, gaseous stack discharge samples are also processed. Tritium is measured via LSC techniques. There is potential for Alpha or Beta contamination of tritium samples, although these contamination levels are very low, it is critical that the laboratory's analytical capabilities are maintained to continue the support of UKAEA's mission and goals. The Health Physics Laboratory requires some of their Liquid Scintillation Counters (LSCs) to be upgraded to new ones in a phased programme of replacement, by gradually phasing out end-of-life equipment. There are three LSC counters in laboratory facilities, in need to be replaced. This tender presents the technical specification for procurement of three Liquid Scintillation Counters, and provides details of the requirements to supply, install, commission, and provide training.
