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Er2 O3作为IPWR堆芯可燃毒物.
針對反轉反應堆(inverted pressurized water reactor‐簡稱IPWR)中子學問題,首先構築瞭IPWR全呎吋堆芯模型,在該模型的基礎上進行瞭堆芯組件臨界計算和中子學相關參數計算,確定瞭噹氫重比為6.5,水棒直徑範圍為7~12 mm得組件柵元呎吋設計範圍.同時通過點燃耗程序分析瞭不同可燃毒物在組件中均勻分佈時,無限增殖繫數隨燃耗的變化,確定選擇Er2 O3作為IPWR堆芯可燃毒物.

This paper built the full size of IPWR (Inverted Pressurized Water Reac‐tor) core mode at first and then based on the mode ,through critical calculation and related parameters 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 finally chose Er2 O3 as IPWR core burnable poison .
