Isotopic Separation System
The isotopic separation system is used to separate tritium from deuterium and hydrogen. It may be used as the stage following electrolysis in the removal of tritium from heavy water or light water. This product shown is normally used for small quantities. It is designed for 8M³/hr

Automatic or manual operation
Stores pure tritium in getter beds
This equipment is based on two molecular sieve packed columns, each cryogenically cooled with liquid nitrogen, and can alternatively be heated in small increments along their length.
Mixed isotopes of hydrogen from an electrolyzer are batch injected into the system and deposited onto one of the two cooled columns. Temperatures are regulated to allow the isotopes to come off the first column in order of molecular size. By manipulating both columns simultaneously and transferring between the columns, it is possible to achieve a clean cut between the different isotopes and to deposit clean pure tritium onto a getter bed, and to discharge pure hydrogen to the stack thus reducing the volume before adding another batch.
The system is contained in a glove box for safety, though every care is taken to provide a safe leak tight system which is fully welded or utilizes high class low leakage fittings where welding is not possible. Some tritium transfer into the box through permeation is unavoidable because of the high temperatures. Valves are all of the bellows sealed types and instrumentation is of the highest caliber.
