摘　　要：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。The computational methods for assemblies with gadolinium pins are discussed.The design of the gadoinia burnable poison for 200MW heating reactor is presented. Manycalculations for benchmarks are performed with the codes TPFAP and WIMS-SN2D. Theresults compared with those from benchmarking codes or with measured critical and pinpower distributions show that the methods are comparable in accuracy to other codes. Sothe methods can be used for the core design of reactors which contain gadolinia burnablepoison.
