Embodiment 1

[0032] Such as figure 1 As shown, in the first embodiment of the neutron counting system of the nuclear power plant simulator of the present invention, it includes a source range detector 101 , a general control platform 102 , and an audio-visual counting module 103 .

[0033] Wherein, the source-range detector 101 is used to simulate the source-range neutron sensor in an actual nuclear power plant, and realizes the function of converting the neutron flux signal into a neutron counting signal.

[0034] The source range detector 101 includes an IO data interface, the IO data interface is connected to an external data source, and a neutron flux signal F is input through the IO data interface. The neutron flux signal F refers to the number of neutrons passing through a unit area per unit time, and the unit is n.cm -2 .s -1 , which has a linear interpolation function relationship with the kernel power.

[0035] The neutron flux signal F includes an analog signal generated by mo...

Embodiment 2

[0045] The difference with the first embodiment is that the control board of the general control platform 102 also has a second data interface, and the second data interface is connected to the audio-visual counting module 103, and the control board of the general control platform 102 The equivalent nuclear power is also generated according to the neutron counting signal N, and the equivalent nuclear power is output through the second data interface. In addition, the neutron counting system described in this embodiment mainly simulates the source range measurement channel in an actual nuclear power plant. Referring to the corresponding relationship table of neutron flux, neutron count value and equivalent nuclear power shown in Table 1, this implementation The variation range of the neutron flux in the example can be 10 -1 n.cm -2 .s -1 ~2×10 5 n.cm -2 .s -1 .

[0046] For example, the neutron flux signal F is 10 -1 n.cm -2 .s -1 , the neutron counting signal N is 8×1...

Embodiment 3

[0069] The difference between this embodiment and the first embodiment of the neutron counting method of the present invention is that the method further includes, using the display screen of the audio-visual counting module 103 to connect with the control board via the second data interface , showing the equivalent nuclear power corresponding to the on-off pulse signal, so that trainees can deepen their understanding of nuclear power while hearing the neutron impact sound from the horn.

[0070] The neutron counting system of the nuclear power plant simulator of the present invention has a simple structure. The above-mentioned system simulates the actual nuclear power plant environment, completes the function of the actual source range detector, and emits a simulated neutron impact sound, which is helpful for relevant training of technicians Correspondingly, the cost of training is also reduced. At the same time, the neutron counting system of the nuclear power plant simulator...

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a neutron counting system and method based on a nuclear power plant full range simulator. Background technique [0002] Due to its complex technology, high difficulty and the characteristics of nuclear safety, nuclear power plants have relatively high requirements for the qualification and ability of operation and maintenance personnel. Nuclear power plants must be operated and maintained by competent personnel in accordance with design standards and specifications. According to the requirements of international practices and national and safety regulations, nuclear power plant operators must hold operating licenses issued by the National Security Bureau, and to obtain corresponding licenses, they must pass the study, training and examination of the full range of nuclear power plant simulators. [0003] The full range simulator of nuclear power plant is the necessar...
