In ITER parlance, the vessel containing the uranium tritide is called a "getter bed." A key design objective for the ITER Storage and Delivery System is to develop a getter bed that meets the unprecedented levels of performance required for fuelling of the Tokamak and which optimizes the design against needs, which can be conflicting. The performance requirements for the bed are obtained from the fuelling needs of the ITER machine. The ability to deliver gas at a high rate and to quickly reload with gas recycled via the Isotope Separation System creates the need for very effective heat transfer for heating and cooling of the hydride material.
Hydrogen and deuterium testing of the bed containing depleted uranium requires having the processing system inside of a glove box similar to the future ITER Tritium Plant, where the glove box forms part of the tritium confinement system.
