[0045] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] The embodiments provided by the present application can be applied to, for example, Figure 1 as shown in the Figure 1 , Figure 1 It is an application environment diagram of an operating status monitoring method for nuclear facilities provided by an embodiment of the present application. The application environment includes: a neutrino detector 101, a first muon detector 102, a second muon detector 103, a nuclear facility 104 to be monitored, and a processing device 105. The nuclear facility 104 to be monitored is disposed between the first muon detector 102 and the second muon detector 103. The neutrino detector 101 is used to collect neutrinos released by the nuclear facility 104 to be monitored to generate neutrino information; the first muon detector 102 is used to collect the number of muons and the muon forward direction angle before the muons emitted by the muon ray source pass through the nuclear facility 104 to be monitored to generate first muon information; the second muon detector 103 is used to collect the number of muons and the muon forward direction angle after the muons pass through the nuclear facility 104 to be monitored to generate second muon information.

[0047] In one embodiment, as Figure 2 shown in Figure 2 It is a schematic flowchart of an operating status monitoring method for a nuclear facility provided by an embodiment of the present application. Taking the application of this method to the Figure 1 application environment as an example, it includes the following steps:

[0048] S201, the neutrino detector collects neutrino information released by the nuclear facility to be monitored.

[0049] Among them, the nuclear facility 104 to be monitored can be any one of a reactor, a dry storage device for spent fuel, and other radioactive substances with beta decay.

[0050] Exemplarily, a neutrino detector 101 is arranged on one side facing the nuclear facility 104 to be monitored. The neutrino collection surface of the neutrino detector 101 needs to face the nuclear facility 104 to be monitored. Since the target nuclides in the nuclear facility 104 to be monitored will undergo nuclear fission, neutrinos are generated. Neutrinos move at high speeds. Compared with traditional neutron detectors, the distance between the neutrino detector 101 and the nuclear facility 104 to be monitored can be adjusted flexibly. When the distance between the neutrino detector 101 and the nuclear facility 104 to be monitored is relatively far, neutrinos can also reach the neutrino collection surface of the neutrino detector 101 before decay. The neutrino detector 101 collects the number of neutrinos released by each target nuclide in the nuclear facility 104 to be monitored and the neutrino energy spectrum of the nuclear facility 104 to be monitored, and sends the number of neutrinos released by each target nuclide and the neutrino energy spectrum of the nuclear facility 104 to be monitored to the processing device. The processing device determines the power of the nuclear facility 104 to be monitored based on the neutrino information sent by the neutrino detector 101.

[0051] S202, the first muon detector collects the first muon information emitted by the muon ray source towards the nuclear facility to be monitored.

[0052] Optionally, the muon ray source can be cosmic rays in nature, or a muon accelerator can be arranged on one side of the first muon detector as the muon ray source.

[0053] Exemplarily, the first muon detector 102 and the second muon detector 103 are respectively divided into j first preset positions, and each first preset position corresponds to each preset position on the nuclear facility 104 to be monitored. The first preset positions of the first muon detector 102 are used to collect the number of first muons released by the muon ray source and the first muon forward direction angle. Each first preset position collects the corresponding number of first muons and the first muon forward direction angle. The first muon detector 102 sends the number of first muons and the first muon forward direction angle corresponding to each first preset position it has collected to the processing device.

[0054] S203, the second muon detector collects the second muon information emitted by the nuclear facility to be monitored.

[0055] Exemplarily, the second muon information is the muon information collected by the second muon detector 103 after the muons released by the muon ray source pass through the first muon detector 102 and the nuclear facility 104 to be monitored. The second muon information includes the number of second muons and the second muon forward direction angle. The first preset positions of the second muon detector 103 are used to collect the number of second muons and the second muon forward direction angle. Each first preset position collects the corresponding number of second muons and the second muon forward direction angle. The second muon detector 103 sends the number of second muons and the second muon forward direction angle corresponding to each first preset position it has collected to the processing device.

[0056] S204. The processing device determines the operating state of the nuclear facility to be monitored according to the particle information. The particle information includes neutrino information and / or muon information. The muon information includes first muon information and second muon information.

[0057] Among them, the operating state of the nuclear facility to be monitored includes the power of the nuclear facility to be monitored and / or the remaining material conditions at each preset position of the nuclear facility to be monitored.

[0058] Exemplarily, the processing device determines the power of the nuclear facility 104 to be monitored according to the neutrino information collected by the neutrino detector 101. According to the first muon information collected by the first muon detector 102 and the second muon information collected by the second muon detector 103, the remaining material conditions at each preset position of the nuclear facility 104 to be monitored are determined.

[0059] The above method for monitoring the operating state of a nuclear facility is applied to a monitoring system. The monitoring system includes a target detector, a nuclear facility to be monitored, and a processing device. The target detector includes a neutrino detector and / or two muon detectors. The two muon detectors include a first muon detector and a second muon detector. The nuclear facility to be monitored is arranged between the first muon detector and the second muon detector. The neutrino detector collects the neutrino information released by the nuclear facility to be monitored. The first muon detector collects the first muon information emitted by the muon ray source to the nuclear facility to be monitored. The second muon detector collects the second muon information emitted by the nuclear facility to be monitored. The processing device determines the operating state of the nuclear facility to be monitored according to the particle information. In the traditional technology, the RPN is used to monitor the operating state of the nuclear facility. If there is an obstacle between the RPN and the nuclear facility, the operating state of the nuclear facility monitored by the RPN will also be affected. In this application, the neutrino detector and / or two muon detectors are used to monitor the operating state of the nuclear facility. The neutrino has a fast propagation speed and a slow decay speed, and the distance between the neutrino detector and the nuclear facility can be adjusted flexibly, improving the flexibility of monitoring the power of the nuclear facility. The muon has a strong penetration ability. Using the muon detector to monitor the operating state of the nuclear facility solves the problem that the shielding object affects the monitoring of the operating state of the nuclear facility.

[0060] It should be noted that in the above embodiment, the target detector includes a neutrino detector and two muon detectors, so that the power of the target nuclear facility and the nuclear fuel position can be monitored simultaneously, which is beneficial to improving the reliability of nuclear security monitoring.

[0061] Optionally, the processing device can determine the operating state of the nuclear facility to be monitored only through one of the neutrino information and muon information. The target detector can only include a neutrino detector, or the target detector can only include the first muon detector and the second muon detector. For example, in one embodiment, the processing device determines the operating state of the nuclear facility to be monitored according to the neutrino information. At this time, the target detector is a neutrino detector, the particle information includes neutrino information, and the processing device determines the power of the nuclear facility to be monitored according to the neutrino information; according to the power of the nuclear facility to be monitored, the operating state of the nuclear facility to be monitored is determined. Or, in one embodiment, the processing device determines the operating state of the nuclear facility to be monitored according to the first muon information and the second muon information. At this time, the target detector can also only include the first muon detector and the second muon detector, the particle information includes the first muon information and the second muon information, and the processing device determines the remaining material situation at each preset position of the nuclear facility to be monitored according to the first muon information and the second muon information, and determines the operating state of the nuclear facility to be monitored according to the remaining material situation at each preset position of the nuclear facility to be monitored, which is not limited here. For the convenience of description, in the following embodiments, the target detector includes a neutrino detector and two muon detectors as an example for illustration.

[0062] In one embodiment, the above S204, the processing device determines the operating state of the nuclear facility to be monitored according to the particle information, which can be implemented in the following manner:

[0063] The processing device determines the power of the nuclear facility to be monitored according to the neutrino information; the operating state includes the power of the facility to be monitored.

[0064] Exemplarily, the neutrino detector 101 sends the neutrino information of the nuclear facility 104 to be monitored collected to the processing device, and the processing device determines the power of the nuclear facility 104 to be monitored according to the neutrino information of the nuclear facility 104 sent by the neutrino detector 101.

[0065] In this embodiment, the processing device determines the power of the nuclear facility to be monitored according to the neutrino information; the operating state includes the power of the facility to be monitored. The neutrino has a fast propagation speed and a slow decay speed, and the distance between the neutrino detector and the nuclear facility to be monitored can be flexibly adjusted, improving the flexibility of monitoring the power of the nuclear facility.

[0066] In one embodiment, the neutrino information includes the number of neutrinos released by the nuclear facility to be monitored collected by the neutrino detector and the neutrino energy spectrum of the nuclear facility to be monitored. The processing device determines the power of the nuclear facility to be monitored according to the neutrino information, which can be implemented in the following manner:

[0067] The processing device determines the power of the nuclear facility to be monitored according to the number of neutrinos and the neutrino energy spectrum.

[0068] Exemplarily, assume that there are i (i≥1) target nuclides in the nuclear facility 104 to be monitored that undergo fission reactions to generate neutrinos. The neutrino detector 101 collects the neutrinos released by each target nuclide released by the nuclear facility 104 to be monitored and the neutrino energy spectrum of the nuclear facility 104 to be monitored, and determines the power P of the nuclear facility 104 to be monitored, which can be expressed by the following relational expression:

[0069]

[0070] Among them, is the neutrino energy spectrum of the nuclear facility 104 to be monitored, P is the power of the nuclear facility 104 to be monitored, and x i represents the fission fraction of the target nuclide i, is the neutrino energy spectrum of the target nuclide i, σ is the cross-section value of the reaction between neutrinos and protons, m is the mass of the target used for detection in the neutrino detector 101, γ is the detection efficiency of the neutrino detector 101, π is the pi, d is the distance between the generation of neutrinos in the nuclear facility 104 to be monitored and the neutrino detector 101, and v i is the number of neutrinos released per fission of the target nuclide i.

[0071] In this embodiment, the processing device determines the power of the nuclear facility to be monitored according to the number of neutrinos and the neutrino energy spectrum. Neutrinos have a fast propagation speed and a slow decay speed, and the distance between the neutrino detector and the nuclear facility to be monitored can be flexibly adjusted, improving the flexibility of monitoring the power of the nuclear facility.

[0072] In one of the embodiments, for the above S204, the processing device determines the operating state of the nuclear facility to be monitored according to the particle information, which can be implemented in the following manner:

[0073] The processing device determines the remaining material conditions at each position of the nuclear facility to be monitored according to the muon information; the operating state includes the remaining material conditions at each position of the facility to be monitored.

[0074] Exemplarily, the first muon detector 102 collects the first muon information emitted by the muon ray source to the nuclear facility 104 to be monitored, and sends the collected first muon information to the processing device; the second muon detector 103 collects the second muon information emitted by the nuclear facility 104 to be monitored, and sends the collected second muon information to the processing device. The processing device determines the remaining material conditions at each position of the nuclear facility 104 according to the first muon information and the second muon information.

[0075] In this embodiment, the processing device determines the remaining material conditions at various positions of the nuclear facility to be monitored according to muon information; the operating state includes the remaining material conditions at various positions of the facility to be monitored. Compared with the traditional method of using an optical camera to monitor the fuel position of a nuclear facility, muons have strong penetration ability and are not easily affected by obstacles between the target detector and the nuclear facility to be monitored, avoiding the influence of obstacles on the monitoring of the operating state of the nuclear facility.

[0076] Figure 3 FIG. is a schematic flowchart of a method for determining the remaining material conditions at various positions of a nuclear facility to be monitored provided by an embodiment of the present application. This embodiment relates to a possible implementation manner of how the processing device determines the remaining material conditions at various positions of the nuclear facility to be monitored according to muon information. On the basis of the above embodiment, as Figure 3 shown, the above method includes:

[0077] S301, the processing device determines the muon scattering distribution width according to the first muon information and the second muon information.

[0078] Exemplarily, let the number of muons Q j1 collected by the first muon detector 102 at each first preset position and the forward direction angle W j1 of the muons, and the number of muons Q j2 collected by the second muon detector at each first preset position and the forward direction angle W j2 . According to the first muon information Q j1 , W j1 at each first preset position, and the second muon information Q j2 , W j2 , determine the muon scattering distribution width d j 1 of each preset position of the nuclear facility 104 to be monitored corresponding to each first preset position.

[0079] S302, the processing device determines the average atomic number and average atomic mass of each preset position of the nuclear facility to be monitored according to at least two muon scattering distribution widths; each muon scattering distribution width corresponds to a different setting position, and the setting position is the setting positions of the two muon detectors.

[0080] Exemplarily, according to the positional relationship between the above first muon detector 102, the nuclear facility 104 to be monitored, and the second muon detector, rearrange the first muon detector 102 and the second muon detector, and determine the muon scattering distribution width d j 2 of each preset position of the new nuclear facility 104 to be monitored again according to the method for determining the muon scattering distribution width described above. According to d j 1 and d j2. Determine the average atomic number and average atomic mass of each preset position of the nuclear facility to be monitored 104, as shown in the following relationship:

[0081]

[0082] Where In is the natural logarithm, L is the path length of the muon in the nuclear facility to be monitored 104, and Z j is the average atomic number of the preset position corresponding to the first preset position j in the nuclear facility to be monitored 104, A j is the average atomic mass of the preset position corresponding to the first preset position j in the nuclear facility 104 to be monitored, b is the relativistic speed, c is the speed of light, and p is the density of the nuclear facility 104 to be monitored. By combining the above equations (1) and (2), the average atomic number and average atomic mass of each preset position in the nuclear facility 104 to be monitored are determined.

[0083] S303: The processing device determines the remaining material situation at the corresponding preset position according to the average atomic number and average atomic mass of each preset position.

[0084] For example, the initial average atomic number of each preset position before the fission reaction of the monitored nuclear facility 104 occurs is Z j1 , the initial average atomic mass is A j1 The average atomic number of each preset position currently calculated is Z j2 , with an average atomic mass of A j2 , according to Z j1 With Z j2 The size of the difference, A j1 With A j2 The size of the difference determines the remaining material at the corresponding preset location. If the difference is small, the target nuclide at the preset location corresponding to the monitored nuclear facility 104 is more remaining. If the difference is large, the target nuclide at the preset location corresponding to the monitored nuclear facility 104 is less remaining.

[0085] In traditional technology, the remaining material situation of the nuclear facility is monitored by installing an optical camera near the nuclear facility. If there is an obstruction between the optical camera and the nuclear facility, the remaining material situation of the nuclear facility cannot be monitored.

[0086] In this embodiment, the processing device determines the muon scattering distribution width according to the first muon information and the second muon information. The processing device determines the average atomic number and the average atomic mass of each preset position of the nuclear facility to be monitored according to at least two muon scattering distribution widths. Each muon scattering distribution width corresponds to a different setting position, and the setting position is the setting positions of two muon detectors. The processing device determines the remaining material condition of the corresponding preset position according to the average atomic number and the average atomic mass of each preset position. Muons have strong penetration ability and are not easily affected by the presence of obstacles between the target detector and the nuclear facility to be monitored, avoiding the influence of the obstacles on the monitoring of the remaining material condition of the corresponding preset position of the nuclear facility.

[0087] In one of the embodiments, the above method further includes:

[0088] The second muon information is the muon information emitted from the nuclear facility to be monitored and collected by the second muon detector after the muons corresponding to the first muon information are incident on the nuclear facility to be monitored.

[0089] Exemplarily, after the muons corresponding to the first muon information are incident on the nuclear facility 104 to be monitored, each target nuclide i that undergoes a fission reaction in the nuclear facility absorbs the incident muons and changes the forward direction angle of the muons. When the muons pass through the nuclear facility 104 to be monitored, both the number and the forward direction angle of the muons change. The second muon information is the muon information collected by the second muon detector after the muons released by the muon ray source pass through the first muon detector 102 and the nuclear facility 104 to be monitored.

[0090] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least a part of other steps or steps or stages in other steps.
