摘要
基于Sobol法,通过对燃料包壳尺寸、燃料富集度等设计输入参数进行拉丁超立方抽样,开展功率峰因子、慢化剂温度系数、控制棒价值等AP1000首循环堆芯物理关键参数对设计输入参数的敏感性分析。分析结果表明:AP1000首循环堆芯物理关键参数对包壳外径、富集度为1.58%、3.20%、3.80%、4.40%的燃料组件、燃料芯块半径、IFBA中硼-10线密度和控制棒导向管尺寸较为敏感。
Based on Sobol method,AP1000 first cycle core key physical parameters such as power peaking factor,moderator temperature coefficient,control rod worth sensitivity analysis can be carried out by the Latin hypercube sampling of input design parameters such as fuel clad diameter,fuel enrichment.The results show that: AP1000 first cycle core key parameters are sensitive to fuel clad outside diameter,fuel assemblies with 1. 58%,3. 20%,3. 80%,4. 40% fuel enrichment,fuel pellet diameter,10 B line density of IFBA and guide thimble diameter.
