Abstract
The thermal diffusion is one of the useful methods of the hydrogen isotope separation. This paper reports on the experiments using Cryogenic-Wall thermal diffusion column cooled by liquid nitrogen which have been performed in the total reflux and the withdraw modes. As using the same inner diameter column, Cryogenic-Wall thermal diffusion column has the higher separation factor, but the lower optimum pressure than Ordinary-Wall thermal diffusion column cooled by water. It is obtained that Cryogenic-Wall column with a smaller inner diameter has the remarkable high separation factor and the higher optimum pressure. In the withdraw mode, the characteristics of the separation factor as a function of the feed rates is obtained about the several inner diameter columns.
