Aqueous and gaseous tritiated streams are to be processed in many Fusion, Fission and Isotope Separation Systems. A number of processes have been proposed. Some of them are well established, others are not yet industrially applied. From an engineering point of view these processes are evaluated for use in industrial plants with large scale separating requirements. Tritium processing experience from fission plants (mainly heavy water reactors) can be directly applied to Fusion Reactor Tritium systems. Sufficient experience for equipment design and material selection for industrial plants is already established.
