摘要: 研究建立了反应堆二次中子源源强的机理性计算方法,并计算了某核电厂反应堆第2循环装料时的二次中子源源强。为验证二次中子源源强的计算结果,计算了反应堆装料第2步完成后堆外源量程探测器的计数率,并与实测结果进行对比。源量程探测器计数率计算结果与实测结果符合得非常好,验证了二次中子源源强计算结果的正确性以及所建立的计算方法的合理性。Abstract: This paper studies and proposes a mechanism-based calculation method of secondary neutron source (SNS) intensity of nuclear reactor, and calculated the SNS intensity of the reactor of a certain nuclear power plant at the refueling outage of the second cycle. In order to verify the calculated SNS intensity, when the step 2 of the refueling process is finished, the counting rate of the ex-core source range detector is calculated and compared with the measured data. The comparison result shows good agreement and indicates the correctness of the SNS intensity calculation result and the reasonableness of the proposed calculation method.
