T/AW049/21 - H3AT ISS

A Supplier will be required to undertake the Preliminary and Final Design phase of the ISS sub-system and potential equipment, and process trials prior to delivery to site at Culham Science Centre.   Upon completion of development trials, 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. These are located in the streams between the 4 cryodistillation columns and promote the formation of H2, D2 and T2.
