摘　　要：本文描述了一种用于CEFR块堆反应堆核测量的系统设计,该系统采用单独的裂变室可实现覆盖反应堆功率全量程的测量。通过simulink仿真模拟裂变室信号以及相关电子学仪表处理过程,分析裂变室在三个工况下的信号性能,并通过不同工况下的信号衔接设计,实现裂变室线性测量反应堆全量程功率的目的,即实现裂变室的宽量程测量。通过裂变室宽量程应用,可以减少探测器、仪表、电缆和安装设施的数量,简化核测量系统,使其成本控制和信号性能上更具优势。This paper describes a system design for the nuclear measurement of CEFR reactor,which uses a fission chamber to measure the full range of power covering the reactor.In this paper,the signal performance of the fission Chamber under three working conditions is analyzed by simulating the simulink simulation of the fission chamber signal and the related electronic instrument processing,and the full range power of the fission chamber linear measurement reactor is realized by the signal connection design under different working conditions,that is,the wide range measurement of the fission chamber is realized.The use of fission chamber wide range applications reduces the number of detectors,instrumentation,cables and installation facilities,simplif ies the nuclear measurement system,and gives it a greater advantage in cost control and signal performance.
