Separation of helium and hydrogen isotopes by ISS (Isotope Separation System) at the TSTA

Separation experiments were performed with Isotope Separation System (ISS) at the TSTA from 1988 through 1989. These experiments included two column experiments with D-T mixture and four column experiments with D-T mixture and impurities (He and H{sub 2}). The objectives of these experiments were to obtain fundamental data of cryogenic distillation columns under wider range of operational condition than previous work, to observe the influence of He on the operation of cryogenic distillation columns, and to obtain fundamental data of cryogenics distillation columns under the influence of He. 2 refs., 7 figs., 2 tabs.
