Abstract: 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.
