本文讨论以钆为可燃毒物反应堆芯的计算方法。给出了２００ＭＷ供热堆钆可燃毒物的设计。用ＴＰＦＡＰ程序和ＷＩＳ－ＳＮ２Ｄ程序对许多基准作了计算。其结果与基准程序的结果、实测临界性和功率分布的结果进行对比。表明本方法与一些基准程序的精度相当。认为本方法可以用于含钆可燃毒物的堆芯设计。 This article discusses the calculation of gadolinium as a burnable poison reactor core. The design of gadolinium combustible poison of 200MW heating reactor is given. Many benchmarks have been calculated using the TPFAP program and the WIS-SN2D program. The results are compared with those of the benchmark program, the measured criticality and the power distribution. This method shows the accuracy of some benchmarks. It is believed that this method can be used for the core design of gadolinium-containing combustible poisons.
