| 摘 要： | 以秦山核电厂一期工程反应堆为例，运用基于蒙特卡罗方法的MCNP程序建立了模拟计算模型，构建出反应堆压力容器内堆芯组件成分及排布，利用MCNP程序中的KCODE卡计算了反应堆中可燃毒物棒数量和位置的变化对有效增值系数Keff值的影响。结果表明，在不考虑控制棒和化学补偿控制对反应堆Keff值影响的情况下，随着可燃毒物棒数量的增多，Keff值呈线性下降的趋势，当毒物棒的布局由密到疏时，Keff值由大变小，这与理论结果一致。

| Abstract: | Taking Qinshan nuclear power plant as an example, in this paper, Monte Carlo method was used in the MCNP procedures for the establishment of nuclear power station simulation model, construct the reactor pressure vessel and vessel core component composition and arrangement, KCODE card was used to calculate the effect of the number and the location of burnable poison control rod factor Keff by the boron acid. The calculation results show that, with the increasing in the number of burnable poison control rod value-added factor Keff shown a downward trend, and with the burnable poison control rod from the dense to sparse, which Keff will be decreasing slowly. This condition is consistent with the theoretical. Key words： |
