Problems solved by technology

[0004] However, the implementation principle of the above-mentioned simulation system is quite different from that of the actual nuclear power unit. At the same time, the important functions of the actual nuclear power unit are simplified, and it is difficult to truly reproduce the relevant training scenarios, so that the system basically loses its training function, and has no effect on the operation. There is some misleading by the staff, which ultimately leads to poor user experience and training for this system

The system can achieve counting function simulation of the neutron fluxes to the maximum extent and is contributed to training of related technicians.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a counting simulation system and method for neutron flux in nuclear power plants. Background technique [0002] The nuclear power plant continuously measures the neutron flux outside the reactor under various working conditions such as shutdown, start-up, and power operation by setting up an external probe, and generates a series of blocking and permitting signals, alarms and alarms after processing the measured signals. Shutdown signal to ensure that the reactor is in a safe and controllable range under any working conditions. The neutron flux counter is an important part of it. The sound in the neutron flux counter system in the main control room is played according to the value of the actual source range. The higher the value, the higher the frequency of the sound, and the lower the value, the higher the frequency of the sound. Low, the operator can roughly judge...
