摘　　要：在压水堆功率运行过程中,由于燃耗效应和硼化效应的原因,一回路硼酸溶液中^(10)B的丰度会随时间不断地发生变化,而核电厂又无法提供^(10)B丰度的实时测量值,从而导致核设计程序对临界硼浓度的计算值在循环中期低于实测值。因此,为了降低堆芯一回路临界硼浓度计算值与实测值之间的偏差,本文基于西安交通大学核工程计算物理实验室(NECP)自主研发的Bamboo-C软件给出了^(10)B丰度的计算方法,该方法能够同时考虑燃耗效应和硼化效应对临界硼浓度的影响。采用本文^(10)B丰度计算方法,对福清核电厂M310机组功率运行历史进行跟踪模拟,并且将一回路临界硼浓度和^(10)B丰度的计算值与实测值进行对比验证。验证结果表明,本文^(10)B丰度计算方法能够改善堆芯临界硼浓度的数值计算结果,具备工业应用的条件。During the power operation of PWR,due to burnup effect and boronation effect,the abundance of ^(10)B in the primary circuit boric acid solution will change continuously with time,and the nuclear power plant can not provide the real-time measured value of ^(10)B abundance.As a result,the calculated value of the critical boron concentration in the nuclear design program is lower than the measured value in the middle of the cycle.Therefore,in order to reduce the deviation between the calculated value and the measured value of the critical boron concentration in the primary circuit of the core,this paper gives a calculation method of ^(10)B abundance based on the Bamboo-C software independently developed by the Nuclear Engineering Computational Physics(NECP)Laboratory of Xi'an Jiaotong University.This method can consider the influence of burnup effect and boronation effect on the critical boron concentration at the same time.Using the ^(10)B abundance calculation method mentioned in this paper,the power operation history of the M310 unit of Fuqing NPP was tracked and simulated,and the calculated values of the primary circuit critical boron concentration and B-10 abundance were compared and verified with the measured values.The verification results show that the ^(10)B abundance calculation method mentioned in this paper can improve the numerical calculation results of core critical boron concentration,and has the conditions for industrial application.
