Fuel Management Design Research of Fusion—Fission Hybrid Energy Reactor

本文根据聚变-裂变混合能源堆方案设计和燃料组件功率分布的特点,利用自主开发的蒙卡-燃耗耦合程序,开展了详细的燃料管理方案设计研究,分别设计了整体后处理的燃料管理方案、双循环燃料管理方案以及分批燃料管理方案,针对这些类型的燃料管理方案,进行了燃耗分析计算,研究了各种燃料管理方案下各区燃耗及主要裂变核素成分随燃耗的变化。根据各燃料管理方案的主要特点和计算分析结果,对比总结了它们的优点和缺点。本文为今后的聚变-裂变混合能源堆提供了燃料管理上的建议,也为进一步的经济性分析优化研究打下了基础。

Based on the scheme design and the fuel assembly power distribution of the fusion-fission hybrid energy reactor,detailed fuel management design research has been done using the independently developed burn-up program in this paper.Fuel management schemes with whole assembly post-process,double cycles and batch-wise cycles are designed.Based on these types of fuel management schemes,burn-up analysis calculation is carried out and zone-wise burn-up as well as the content of main fission nuclides are researched respectively.According to the main characters and calculation analysis results of the fuel management schemes,the advantages and disadvantages are balanced and summarized.This paper provides some advice for the fuel management of the fusion-fission hybrid energy reactor,which can be used for further economic optimization analysis.
