- ПубликацияТолько метаданныеCascades with Flow Expansion for Simultaneous Concentration of Intermediate Components(2019) Fomin, D. N.; Smirnov, A. Y.; Sulaberidze, G. A.; Mustafin, A. R.; Смирнов, Андрей Юрьевич; Сулаберидзе, Георгий Анатольевич; Мустафин, Андрей Рушанович© 2019, Springer Science+Business Media, LLC, part of Springer Nature.A cascade scheme allowing two intermediate-mass isotopes to be concentrated in a single cascade above the maximum admissible concentrations at the outputs of ordinary cascades is proposed. A cascade with two flow expansions and two additional product flows is used for this. For the example of a mixture of tungsten isotopes, it is shown that the concentrations of 183W and 184W can be increased simultaneously up to 70 and 80%, respectively. In addition, additional product flows can be equal to 50–70% of the primary (end) product flow of the cascade.

- ПубликацияОткрытый доступOptimization of a system of square cascades for efficient concentration of intermediate isotopes(2020) Azizov, T. E.; Smirnov, A. Yu.; Sulaberidze, G. A.; Mustafin, A. R.; Смирнов, Андрей Юрьевич; Сулаберидзе, Георгий Анатольевич; Мустафин, Андрей Рушанович© 2020 Published under licence by IOP Publishing Ltd.The problem of obtaining relatively high concentrations of stable isotopes of intermediate mass numbers is considered. The object of research is a connection of three ordinary square cascades. The possibility of simultaneous concentration of isotopes of intermediate masses in different output flows of cascades is shown. The dependencies of the parameters of the cascade schemes under consideration are investigated. The method of optimization of such system of square cascades according to the criterion of minimum relative total flow at given concentrations of target components is proposed. Calculations were made on the example of isotope mixtures with the number of components 4 and 5.
- ПубликацияОткрытый доступObjective function at optimization of separation cascades(2019) Zeng, S.; Jiang, D.; Mustafin, A. R.; Smirnov, A. Y.; Sulaberidze, G.; Borisevich, V. D.; Мустафин, Андрей Рушанович; Смирнов, Андрей Юрьевич; Сулаберидзе, Георгий Анатольевич; Борисевич, Валентин Дмитриевич© 2019 Author(s). The optimization of the parameters for separation cascades is of great importance in their designing. The optimal cascade is usually construed as an installation which allows obtaining the required amount of a marketable product at the lowest unit cost. In many situations pertaining to the case, the cascade comprising a minimum possible number of separation elements (for example, gas centrifuges) has the minimum unit cost. However, there are other criteria, optimization by which leads to another set of the cascade parameters. In this connection it seems important to analyze the objective functions used at the optimization as well as their interactions. The paper proposes a method of optimizing the cascades for the isotope separation based on genetic algorithms. The use of such optimization methods in the theory of cascades is promising because they are resistant to specifying initial approximations and practically independent of the objective function type, as well as easily adaptable to changes in the dimension of the space. These specific features are often the main problems in optimizing the parameters of separation cascades. As an example, optimizing the separation cascade with variable stage separation factors for natural uranium enrichment is considered. The optimization is performed by various criteria of efficiency. The results obtained have made it possible to compare the parameters of the cascades optimized by various criteria and to identify the relationships between them. The developed method can be adapted to optimizing various cascade options for the separation of both binary mixtures and multi-component mixtures.
- ПубликацияОткрытый доступPeculiar properties of transient processes in cascades with additional product flow(2020) Zeng, S.; Jiang, D.; Mustafin, A. R.; Smirnov, A. Y.; Sulaberidze, G. A.; Borisevich, V. D.; Мустафин, Андрей Рушанович; Смирнов, Андрей Юрьевич; Сулаберидзе, Георгий Анатольевич; Борисевич, Валентин Дмитриевич© 2020 Published under licence by IOP Publishing Ltd.One of the important stages in the campaign for separation of multicomponent isotopic mixtures is bringing the separation cascade to a stationary mode of operation. This process, depending on the applied separation method, can be characterized by a relatively long time with associated consumption of the working substance and operating costs. Therefore, the search for the values of the control parameters of the cascade at which it is possible to reduce the transient process time is practically a significant problem in the theory of isotope separation in cascades. One of the current trends in the modern theory of cascades is the study of physical laws of stationary mass transfer in cascades with additional outgoing flows. Such cascades can find application for solving a number of urgent problems, in particular, obtaining relatively high concentrations of isotopes with intermediate masses. At the same time, the laws of unsteady mass transfer in such cascades remain poorly understood. The paper analyses the key patterns of transient processes in a square cascade with an additional product flow. The interconnections between the time of bringing such a cascade to the stationary mode and the external conditions under which the process of separation of the mixture occurs are revealed.
