Abstract

This article presents four strategies for separating two stable isotopes of iridium with 99.9% purity. The cascades employed are tapered, square, and squared-off. To design and optimize these cascades, four computational codes were developed using the PSO algorithm. The findings indicate: (1) The tapered cascade strategy cannot achieve 99.90% separation for either type of centrifuge; (2) For the first centrifuge, both square and squared-off cascades strategy successfully separate the isotopes, achieving 99.90% purity, with recovery percentages of ¹⁹¹Ir and ¹⁹³Ir at 99% and 33%, respectively; (3) For the second centrifuge, only the square cascade strategy achieves 99.90% separation, with recovery percentages of approximately 99% for both isotopes.

气体离心法分离铱元素稳定同位素的四种策略比较

本文介绍了以 99.9% 的纯度分离两种稳定同位素铱的四种策略。采用的级联包括锥形、方形和方形级联。为了设计和优化这些级联，使用 PSO 算法开发了四个计算代码。结果表明：(1) 锥形级联策略在两种离心机中都无法达到 99.90% 的分离度；(2) 在第一种离心机中，方形和方形级联策略都成功分离了同位素，纯度达到 99.90%，191Ir 和 193Ir 的回收率分别为 99% 和 33%；(3) 在第二种离心机中，只有方形级联策略达到了 99.90% 的分离度，两种同位素的回收率约为 99%。
