Title: Invention report process for separation of uranium isotopes

Abstract

A new concept for separation of the isotopes of uranium has been developed. The invention consists of a new process with essentially no moving parts. The new process is called the Ionized Vapor Process and is described in this report.

  • A small twelve-stage gaseous dlffusion cascade was built for the measurement of the barrier separation factor for uranium isotopes. The experiments were performed in a wide range of operating conditions, with the mass flow rate of gaseous uranium hexafluoride at the separation inlet of the order of 1 g/sec under mean operating conditions. The experimental results are presented and compared with theory. Within the precision of the measurements, the theoretical values can be adjusted to the experimental data by choosing an adequate fictitious mean pore radius, different from the permeability pore radius, and an adequate value of the mass transfermore » boundary layer thickness. This adjustment, however, is not entirely satisfactory throughout the whole range of data. (J.S.R.)« less
  • Preliminary results on the separation of uranium isotopes by the nozzle process, which is based on the pressure diffusion in a free expanding jet stream, are reported. A description is given of the apparatus used, and the optimum operating conditions are determined. (J.S.R.)
  • Preliminary studies were made of the feasibility of using the gaseous diffusion process for the production of enriched isotopes of certain specific elements which are of interest in various phases of the United States' nuclear program. The results of these studies indicate the gaseous diffusion process is probably the most practicable method of separating the isotopes of tungsten, molybdenum, and xenon to produce mnterials with the desired characteristics. In each of these cases one is confronted with the problem of separating the isotopes of a multicomponent mixtare: in the case of tungsten the desired isotope W/sup 184/ is a midd1emore » isotope in the naturally occurring mixture. 8pecial modes of operntion are required in order to enrich a mixture with respect to a middle isotope. Since all of the considerations which apply to the separation of the various isotopes mentioned above are included in a discussion of the tungsten problem, only the specific problem of enriching the desired isotope of tungsten is discussed.
