Abstract

This article presents results of development of the mathematical model of nonstationary separation processes occurring in gas centrifuge cascades for separation of multicomponent isotope mixtures. This model was used for the calculation parameters of gas centrifuge cascade for separation of germanium isotopes. Comparison of obtained values with results of other authors revealed that developed mathematical model is adequate to describe nonstationary separation processes in gas centrifuge cascades for separation of multicomponent isotope mixtures.

Highlights

  • Gas centrifuge (GC) method of isotope separation is industrial method of uranium enrichment

  • Process gases are used for isotope separation by GC method

  • Actual task is full-scale research of nonstationary process. This problem had been discussed in the papers [1,2,3,4,5,6,7], authors of which had developed of dynamic stability principles, analytical and numerical solution methods of nonstationary hydraulic equations and mathematical models of nonstationary processes in free cascades

Summary

Introduction

Gas centrifuge (GC) method of isotope separation is industrial method of uranium enrichment. Actual task is full-scale research of nonstationary process This problem had been discussed in the papers [1,2,3,4,5,6,7], authors of which had developed of dynamic stability principles, analytical and numerical solution methods of nonstationary hydraulic equations and mathematical models of nonstationary processes in free cascades. These processes was researched in the cascades for uranium isotopes separation. We have developed of mathematical model of nonstationary hydraulic processes in gas centrifuge cascade for separation of multicomponent isotope mixtures and realized it as program software.
