摘　　要：利用MONK程序对MOX热室项目燃料贮存水池进行了核临界安全分析。针对给定的水池尺寸和燃料棒数量,确定燃料以分区方式贮存。选取国际公布的临界基准实验数据,验证并确定MONK程序计算分析类似物料形态时的偏倚和次临界限值,其次进行保守假设,确定贮存水池在正常及事故工况下其中子有效增殖因数,评价贮存水池的安全性。计算结果表明,贮存水池在最危险事故工况下,其最大中子增殖因数小于次临界限值,系统处于临界安全状态。The MONK code was used to analyze the nuclear critical safety of the fuel storage tank for the MOX hot room project.The fuel partition storage method was determined by the given tank size and fuel rod number.The critical benchmark data published internationally were selected to verify and determine the MONK code to calculate the bias and subcritical limits of similar material forms.The conservative hypothesis was carried out to determine the effective neutron multiplication factor of the storage tank which was under normal and accident conditions,and to evaluate the safety of the storage tank.The calculation results show that the maximum neutron multiplication factor of the storage tank is less than the sub-critical limit under the most dangerous accident condition,and the system is in the critical state of safety.
