The system will undergo a Factory Acceptance Test (FAT) prior to site delivery. Installation, a Site Acceptance Test (SAT) in conjunction with supplier, and integration into the H3AT Tritium Loop will be carried out by the Systems Integrator/Integrated Control System contractor(s). Anticipated system description The Isotope Separation System (ISS) separates a mixture of the six different Q2 (hydrogen) forms into streams containing predominantly H2 (protium), D2 (deuterium) and T2 (tritium) species. Cryo-distillation is the chosen technology. Cryodistillation exploits the small difference in volatility between the isotopes to achieve separation. The quantities of isotopologues of hydrogen – HD, HT and DT are reduced in the system using packed beds of catalyst, known as equilibriators. ## CPV classification Installation services (except software) Compressors for refrigerating equipment Heat-exchange units, air-conditioning and refrigerating equipment, and filtering machinery Heat-exchange units and machinery for liquefying air or other gases Heat-exchange units Heat pumps Machinery for liquefying air or other gases Distilling, filtering or rectifying apparatus Installation services of electrical and mechanical equipment Installation services of electrical equipment Installation services of electricity distribution and control equipment Source Find a Tender (UK) · Notice ocds-h6vhtk-02a2b6-2021-04-06T11:36:26+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-02a2b6-2021-04-06T11:36:26+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
