摘　　要：研究了MC方法在插棒法空间效应修正因子计算中的应用。用MCNP／4B计算了脉冲堆稳态堆芯第一循环插棒前后探测器位置的中子注量率,得到了探测器位置的空间因子。设计了修正空间效应的方法,并用该方法测量了脉冲堆所有控制棒的积分价值,结果令人满意。The MC method to modify spatial effects in rod-insertion is studied in this paper. With MCNP/4B code, Neutron flux at detector position in Pulsed Reactor has been calculated when the rods were at the top and the bottom position. The spatial factors at the detector have been calculated. A Modified spatial effects method depended on MC calculation was designed. Using this method, all control rods integral worth have been measured in Pulsed Reactor, and the satisfied results are obtained.
