摘要

运用蒙特卡罗方法中的MCNP程序建立秦山某核电站模拟计算模型

构建出反应堆压力容器及压力容器内堆芯组件成分及排布

利用KCODE卡计算反应堆中硼酸质量分数对有效增值系数Keff值的影响。计算结果表明:在不考虑控制棒和可燃毒物对反应堆有效增值系数Keff值影响的情况下

随着硼酸质量分数的增大

有效增值系数Keff值线性从1.33047降到1.02484

计算结果与实际值一致。

Abstract

In this paper

Monte Carlo method were used in the MCNP procedures for the establishment of Qinshan nuclear power station simulation model

construct the reactor pressure vessel and vessel core component composition and arrangement

KCODE card were used to calculate the effect of the effective value-added factor Keff by the boron acid .The calculation results show that

without considering the control rods and the burnable poison on the reactor effective value-added factor Keff

with the increasing of the boric acid concentration

Keff linear dropped from 1.330 47 to 1.024 84

the results consistent with the actual value.
