Embodiment 1
[0051] figure 2 A structural block diagram of a nuclear power plant core parameter monitoring system provided by an embodiment of the present invention. like figure 2 As shown, the nuclear power plant core parameter monitoring system includes: a measurement component 10 and a signal processing unit 20 electrically connected to the measurement component 10, wherein:
[0052] The measurement assembly 10 includes a plurality of first measurement assemblies 110 and a plurality of second measurement assemblies 120, and each first measurement assembly 110 and each second measurement assembly 120 respectively include a plurality of self-powered neutron detectors 111 for real-time To collect core neutron flux density signals, multiple self-powered neutron detectors are distributed axially and / or radially around the core of the nuclear power plant;
[0053] The signal processing unit 20 includes a core neutron flux density signal processing cabinet 21, which is used to receive the ...
Embodiment 2
[0077] Image 6 It is a schematic flowchart of a nuclear power plant core parameter monitoring method provided by an embodiment of the present invention. like Image 6 As shown, the core parameter monitoring methods of nuclear power plants include:
[0078] Step S1: Multiple self-powered neutron detectors in the measurement component collect core neutron flux density signals in real time.
[0079] Step S2: Send the core neutron flux density signal to the core neutron flux density signal processing cabinet in the signal processing unit.
[0080] Step S3: The core neutron flux density signal processing cabinet processes the received core neutron flux density signal.
[0081] Step S4: Send the processed core neutron flux density signal to the core online monitoring system.
[0082] Step S5: The online core monitoring system monitors the received processed core neutron flux density signal in real time.
[0083] Further, the nuclear power plant core parameter monitoring method...
