What is being bought

Published requirement description

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.
