## Description

The Isotope Separation System \(ISS\) is a sub-system of the H3AT Facility ITER-like Tritium Loop, designed to separate hydrogen isotope gas mixtures by cryogenic distillation\. It will take mixed hydrogen isotopes from the Hydrogen Purification System and protium from the Water Detritiation system, to produce isotope streams to suit ITER, DEMO and H3AT research requirements\. This sub-system will feed tritium and deuterium to the Storage and Distribution System and protium to the Water Detritation System\. This system will comprise 4 cryogenic distillation columns, cold box, valve box, packed bed reactors \(equilibriators\), expansion vessels and refrigeration plant\.
