| Abstract: | Experiments on the separation of H2-HD isotopic gas mixture were performed with a 1,020 mm-height “Cryogenic-Wall” thermal diffusion column with a heated tube of 9.63 mm-outer-radius and a cooled tube of 14.21 mm-inner-radius which was cooled by liquid nitrogen. Abandance ratios of HD to H2 in the feed, product and waste flow were measured by stable isotope mass spectrometer Finnigan MAT252. Our rigorous numerical code has predicted dependence of separation factors obtained experimentally upon the operating pressure fairly well. |
