摘要
针对反转反应堆(inverted pressurized water reactor-简称IPWR)中子学问题,首先构筑了IPWR全尺寸堆芯模型,在该模型的基础上进行了堆芯组件临界计算和中子学相关参数计算,确定了当氢重比为6.5,水棒直径范围为7～12 mm得组件栅元尺寸设计范围.同时通过点燃耗程序分析了不同可燃毒物在组件中均匀分布时,无限增殖系数随燃耗的变化,确定选择Er2O3作为IPWR堆芯可燃毒物.
This paper built the full size of IPWR （Inverted Pressurized Water Reactor） core mode at first and then based on the mode, through critical calculation and related parame- ters calculation of neutronics, made sure that the H/HM was 6.5 and the diameter range of water hole was 7 - 12 mm. At the same time, by use of origen we analyzed when different burnable poison were evenly distributed in assembly, the Kinf changed with burnup, and fi- nally chose Er203 as IPWR core burnable poison.
