Effective parameters of cascades with a given number of gas centrifuges in stages for stable isotope separation

The paper considers two methods developed for calculating squared-off cascades of gas centrifuges taking into account variable separation factors of gas centrifuges and a given concentration of the target isotope in outlet streams. The first method optimizes feeding streams of stages in individual sections corresponding to the stage type; the second uses a calculation scheme varying the cuts of partial component streams for profiling the stage feeding stream changing along the cascade. A computational experiment was conducted to separate molybdenum hexafluoride in a three-stream cascade of two stage types. An example of ⁹²Mo concentration demonstrates characteristic features of cascades calculated by the compared methods.
