“…Their research shows that the total flow is not suitable as an optimization criterion in cascades with variable separation factors. In 2020, Azizov et al optimized a single square cascade with a specified configuration in order to avoid searching for the initial approximation for the concentration of the components of the separable mixture in outgoing flows [11]. In 2020, Imani et al optimized a transient square cascade based on the PSO algorithm to achieve the maximum product [12].…”

This paper presents the optimization of a system of square cascades for separating the middle components of xenon. It also presents the optimal use of square cascades in this system. As an example, the separation of 130 Xe, an element whose middle isotope is much more complex than any of the other isotopes of xenon, is provided. The Grey Wolf Algorithm is applied for optimization. and the parameters of cascade feed flow rate, cut off the cascade, feed location, feed flow of gas centrifuges (GC), and the cut of the first stage are optimized in such a way that the maximum recovery of the target isotope and the maximum cascade capacity are achieved. Based on the optimization results, the more steps the cascade has, the fewer separation steps are needed for the nine selected cascades with 180 GCs. As a result, both the recovery factor and the amount of product increase.
