ANALYSIS OF CASCADES COMPOSED OF TWO TYPES OF SEPARATORS BASED ON THE SEGMENTED Q-CASCADE

It is possible that an isotope separation cascade uses two types of separators having diff erent separation factors. Arrangement of the separators in the cascade may aff ect its separation performance and, therefore, fi nding the appropriate arrangement is of interest in practice. Six arrangements are considered, four of which have the schemes of a single cascade with four segments, and two have the schemes of a double cascade with two segments on each cascade. Based on the segmented Q-cascade, diff erent separators are installed in diff erent segments. Taking the cascade relative total fl ow as the objective of optimization, analyses are performed on the relations of the relative total fl ow with separation factors and the ratio of the two separators. The results show that diff erent arrangements result in diff erent performances, which can be signifi cant. The double cascade scheme is the best.
