A portable neutron detector signal dynamic simulation device

Abstract

The invention provides a portable neutron detector signal dynamic simulation device. The device comprises a back plate and a man-machine interaction module, a boron proportional counter tube detector signal simulation module, a compensated ionization chamber detector signal simulation module, a long ionization chamber detector signal simulation module, a fission chamber detector signal simulation module, an analog quantity module, a digital quantity module and a control communication module which are connected and communicated through the back plate, wherein the man-machine interaction module acquires data input by a user and distributes the data to the boron proportional counter tube detector signal simulation module, the compensated ionization chamber detector signal simulation module, the long ionization chamber detector signal simulation module, the fission chamber detector signal simulation module, the analog quantity module and the digital quantity module through the control communication module and the back plate to generate corresponding simulation signals. By the device, RPN neutron detector output signals and RPN-associated external system output signals are simulated, and a technical means is provided for the equipment debugging, logic function checking and fault detection of an RPN system.

Description

technical field [0001] The invention relates to the technical field of nuclear power safety measurement, in particular to a portable neutron detector signal dynamic simulation device. Background technique [0002] The external nuclear instrumentation system (RPN) uses a series of neutron detectors distributed outside the reactor pressure vessel of the nuclear power plant to continuously monitor the reactor power, power change rate and axial distribution of power, and display various signals measured It is one of the important systems directly related to the safety of the reactor to record and feed back the information on the status of the reactor during reactor loading, shutdown, start-up and power operation. [0003] At present, the RPN system of nuclear power plants does not have a special neutron detector signal simulation device to realize equipment debugging and fault diagnosis, which affects the safe and stable operation of nuclear power plants. Therefore, there is an...
