研制了基于脉冲堆核测量系统探测器的数字反应性仪。选择适合该堆动态反应性实时监测的数值计算和数字滤波方法,研究了落棒法和插棒法测量控制棒价值的空间效应的修正方法。经过在脉冲堆上测量验证,结果令人满意。
A digital reactivity meter based on the detector of pulsed heap nuclear measurement system was developed. The numerical calculation and digital filtering method suitable for the real-time monitoring of the reactor’s dynamic response are selected to study the correction method of the space effect of the falling rod method and the stick rod method to measure the value of the control rod. After the pulse stack on the measurement verification, the results are satisfactory.
