Molybdenum Isotope Separation in a Cascade with a Specified Number of Gas Centrifuges in Stages

  • Published:
Atomic Energy Aims and scope

A method of calculating and optimizing a multi-flow cascade with a specified number of gas centrifuges in stages on cuts of their partial flows were developed. A special feature of the method is an iterative fitting of the separation coefficients of the gas centrifuges that depend on the feed flow and the division factor of the flow. A computational experiment was conducted on the separation of molybdenum hexafluoride and concentration of the isotopes 98Mo in an additional product and 100Mo in the waste of the cascade. The basic factors that affect the efficiency in concentrating the components and are associated with the cascade feed and the types of stages in terms of the number of gas centrifuges are determined. It is shown that the feed flows and the separation coefficients of the stages of such cascades differ significantly from those of rectangular and rectangular-sectioned cascades.
