Abstract

ABSTRACT Due to the higher flexibility of square cascades than tapered cascades, this research focuses on the design and optimization of square cascades to provide the enriched uranium used in the fresh fuel of a power reactor with different enrichment levels. In order to design and optimize square cascades, two computational codes based on the particle swarm optimization algorithm and the grasshopper optimization algorithm have been developed for the design and optimization of square cascades. The results show that by using optimal square cascades, it is possible to directly produce the fresh enriched uranium required for a power reactor at different enrichment levels (4.1%, 3.7%, and 3.3%), and there is no need to dilute the products enriched by natural or depleted uranium, and the mixing unit can be removed from enrichment facilities. Also, the results obtained from both algorithms show that the total number of optimized square cascades and gas centrifuges required for the production of the annual fuel for a power reactor are very close to each other and have a difference of about 0.65–1.24%.

用PSOA和GOA设计和优化方形级联，为核动力反应堆提供新鲜燃料

摘要:由于方形叶栅比锥形叶栅具有更高的灵活性，本文研究了方形叶栅的设计和优化，以提供不同浓缩水平的动力堆新燃料所使用的浓缩铀。为了设计和优化方形叶栅，开发了基于粒子群优化算法和蚱蜢优化算法的两种计算程序来设计和优化方形叶栅。结果表明，采用最优方级联可以直接生产不同浓缩水平(4.1%、3.7%和3.3%)的动力堆所需的新鲜浓缩铀，无需对天然铀和贫铀浓缩产物进行稀释，混合装置可以从浓缩设施中移除。同时，两种算法的计算结果表明，优化后的方形叶栅和气体离心机生产动力堆年燃料所需的总数非常接近，相差约为0.65 ~ 1.24%。
