数字化核仪表系统样机堆上试验及验证

针对目前国内核电厂核仪表系统设备主要依赖进口的现状，设计研发了一套数字化核仪表系统样机，系统样机主要包括中子探测器组件、信号调理和处理样机以及信号监控设备。通过介绍样机在商用堆上的安装和试验情况，详细分析了反应堆启堆、升功率、满功率及降功率运行期间的试验数据。试验结果表明，中子探测器与信号调理和处理样机配合良好，整套系统样机运行稳定可靠。 

Test and Verification for Digital Nuclear Instrumentation System Prototype on Reactor

In view of the current situation of nuclear instrumentation system equipment mainly relying on import in the current domestic nuclear power plant, a set of digital nuclear instrumentation system prototype was designed and developed. The system prototype mainly includes neutron detector assembly, signal conditioning and processing prototype and signal monitoring equipment. By introducing the installation and test of the prototype on the commercial reactor, the test data during reactor startup, power increase, full power and power reduction are analyzed in detail. The test results show that the neutron detector cooperates well with the signal conditioning and processing prototype, and the whole system prototype runs stably and reliably.
