摘要
基于第三代先进非能动压水堆核电厂的设计特点、运行方式及其复杂的燃料组件设计,考虑各种能谱硬化因素,研究组件燃耗计算的运行条件组合,获得指定燃耗深度下的核素密度。建立乏燃料贮存格架的临界计算模型,并对临界安全分析中的关键因素(如末端效应、可信事故工况等)进行详细研究,最终初步设计出满足我国最新(临界)标准和要求的、可应用于实际工程的高密度乏燃料贮存格架。
Based on the design characteristics, operational strategies, as well as the complicated fuel assembly designs, factors leading to a harder neutron spectrum are considered and a combination of operational parameters is identified to obtain the conservative isotopic inventories. Criticality analysis models are built, and factors such as the end effect and the credible accident conditions are studied in detail. Finally, a primary(criticality) design of the high density spent fuel storage rack is developed which meets the most updated(criticality) criteria and can be used in NPP projects.
