摘要
在临界安全分析中采用燃耗信任制是实现核电厂乏燃料组件密集化贮存的基础之一。本文针对非能动先进压水堆核电厂研究了燃耗信任制的分析方法,建立了完整的计算体系,并在此基础上针对先进压水堆核电厂燃料组件的设计特征以及机械补偿(MSHIM)运行策略等特点,分析其轴向燃耗和温度分布以及组件径向富集度分布等关键参数对临界安全分析的影响,相关研究结果对乏燃料密集化贮存设计的工程应用具有实际的借鉴意义。
This paper focuses on the criticality safety analysis of the spent fuel storage design for passive advanced PWR employing burnup credit (BUC) method. Combined with the feature of fuel assembly design and operation strategy of passive advanced PWR, such factors as radial enrichment design, axial temperature distribution, and burnup shape in fuel assemblies, etc. are considered in this paper. Some suggestions are concluded based on the obtained results for the BUC application on spent fuel dense storage design of advanced PWR.
