TOPAZ‐Ⅱ反应堆的中子通量密度很低，这使其在运行过程中引入的135 Xe 反应性很小，其数值难以采用现有的蒙特卡罗程序进行计算。本文考虑了中子价值对反应性的作用，采用 MVP‐BURN 程序对TOPAZ‐Ⅱ反应堆的135 Xe 小反应性进行了计算。该方法可为其他类似反应堆的小反应性计算提供参考。

Due to the very low neutron flux density of TOPAZ‐ Ⅱ reactor ,the 135 Xe reac‐tivity is too small for the Monte Carlo code to get the accurate results .In this paper ,the adjoint neutron flux was taken into account ,and the MVP‐BURN code was used to calculate small 135 Xe reactivity .This method can also provide a reference for the calcula‐tion of small reactivity for other reactors .
