## Summary

The United Kingdom Atomic Energy Authority is planning a procurement process titled "H3AT ISS" within the installation services industry, specifically for the Culham Science Centre located in Abingdon, Oxfordshire. The procurement is currently in the planning stage, with an anticipated future notice date set for 15th July 2021. This tender involves the design and installation of the Isotope Separation System (ISS), requiring expertise in engineering and installation services pertaining to complex scientific equipment.

This procurement presents a valuable opportunity for businesses specialising in engineering, design, and installation of mechanical and electrical systems, particularly those with experience in high-tech environments. Companies offering services related to cryo-distillation, testing equipment installation, and integration within specialised scientific systems would be particularly well-suited to compete. Engaging with this project could lead to potential long-term contracts and partnerships in the growing field of fusion research.

## Notice

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. 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.

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.
