Design and Effect of Pulse Signal Generator for Simulation Reactor Test in Semi-physical Technology

为适应核测量仪表开发过程中常规功能性能试验和堆上试验的需求,设计了半实物堆上试验脉冲信号发生器。设计基于对脉冲信号特点的分析,采用虚拟仪器的概念,结合反应堆信号随机性特点和反应堆启动过程的实测数据,模拟反应堆上试验脉冲信号的频率变化特性,并介绍了该方法应用在核测量仪表测试中的效果。

In order to adapt to the needs of the routine functional performance test and heap test during the development of nuclear measurement instruments,a test pulse signal generator on the semi-physical reactor was designed. The design is based on the analysis of the characteristics of the pulse signal and uses the concept of a virtual instrument. It combines the random signal characteristics of the reactor and the measured data of the reactor startup process to simulate the frequency variation characteristics of the test pulse signal on the reactor. The method is also applied to nuclear measurement instruments. Test effect.
