Gas Chromatography and Thermal Cycling Absorption Techniques for Hydrogen Isotopes Separation in Water Detritiation Systems

This work introduces state-of-the-art water detritiation processes and discusses the main technologies materials adopted. Focus is given to gas chromatography (GC) thermal cycling absorption process (TCAP), which are studied as potential back-end for tritium recovery through a system designed small-scale unit. GC TCAP evaluated critically in order establish their applicability final purification of DT stream recovered at bottom cryo-distillation column Both solutions (GC with an inverse column) exhibit safe feasible operation modes characterised by good technological level; furthermore, both these meet design specifications required proposed application. However, use preferred, since this can operate modest temperature producing streams (D2 T2) better purity.
