摘要
堆外通量测量电离室刻度试验是方家山核电厂定期物理实验之一,该试验利用KME热功率测量和堆内中子通量图测量的结果进行RPN系数刻度,使RPN系统能够准确地反映出反应堆的实际功率水平和堆内轴向功率偏差的情况。方家山使用ETALONG程序对该试验数据进行处理获得KU、KL、α系数,由于该软件为封闭式,无法获得其内部计算方法,本论文利用堆内外校刻的原理对75%FP试验数据进行处理,并与软件处理结果进行对比,以验证该方法的可用性。
External Flux Measurement Ionization Chamber Calibation Test is one of the Fangjiashan nuclear power plant regular physical experiments,which using the results of KME thermal power measurement and reactor neutron flux pattern measurement to calibrate RPN calibration coefficient,so that RPN system can accurately reflect the reactor actual power level and reactor axial power difference.Fangjiashan use the ETALONG program to obtain KU, KL, alpha coefficient of the test data,because the software is closed, it can not get its internal calculation method.In this paper, the principle of internal and external calibration is used to process the data of 75%FP test,and the results are compared with the software,in order to verify the availability of the method
