Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The method for generating the nuclear data cross-section library provided by the present disclosure may be executed by a device for generating the nuclear data cross-section library provided by the present disclosure, and may also be executed by an electronic device provided by the present disclosure, where the electronic device may include but is not limited to a mobile phone, a desktop computer, a tablet computer, and other terminal devices, and the method for generating the nuclear data cross-section library provided by the present disclosure is executed by the device for generating the nuclear data cross-section library provided by the present disclosure, and is not limited to the present disclosure, and is hereinafter referred to as "device" for short.
A method, an apparatus, a computer device, and a storage medium for generating a nuclear data cross-section library according to the present disclosure are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for generating a nuclear data cross-section library according to an embodiment of the present disclosure.
As shown in fig. 1, the nuclear data cross-section library generation method may include the steps of:
in step 101, basic information of each nuclide in the nuclide list is acquired.
It should be noted that the nuclide refers to an atom having a certain number of protons and a certain number of neutrons. Nuclei having different nuclear properties of the same isotope have the same number of protons and different numbers of neutrons, and have different structural modes, thereby exhibiting different properties.
The core design is the upstream and core of the reactor design, and the nuclear database for nuclear power plant core design may be a database storing relevant information necessary for nuclear reactor calculation, and may include information such as version information, development date, energy cluster structure, and nuclide list, which is not limited herein.
In the embodiment of the disclosure, the nuclear database for core design of the nuclear power plant may be obtained first, and then the basic information of each nuclide in the nuclide list may be extracted from the nuclear database for core design.
It should be noted that, in the embodiments of the present disclosure, a general database may be used as the nuclear database for designing the core of the nuclear power plant.
And 102, determining a nuclide file corresponding to each nuclide according to the basic information of each nuclide.
Specifically, the nuclide file corresponding to each nuclide can be determined according to the basic information of each nuclide. Wherein, the nuclide file comprises a plurality of section data files. It should be noted that the profile data files are independent of each other, so that any profile of any nuclear species can be corrected, tested and verified conveniently. Since each nuclide corresponds to a respective nuclide file, the nuclide can be easily extended, deleted, or modified, and is not limited herein.
Alternatively, in the embodiment of the present disclosure, the target problem may be determined according to the current core design task, and then the target core material information and the target calculation function information may be determined according to the target problem.
It should be noted that, since only a part of the nuclide information may be involved in the problem to be solved, the core design task to be solved currently, i.e., the current calculation requirement, may be used to determine the target problem to be solved in the present disclosure.
Wherein the target nuclear species may be a nuclear species required for the calculation.
The target question may correspond to the target calculation function information, for example, if the current target question is a burnup question, the target calculation function information may be a calculation type related to burnup, and is not limited herein. Alternatively, the method may also be a conventional calculation problem, a critical calculation problem, a detector simulation calculation problem, and the like, and is not limited herein.
It is understood that, according to the objective problem and the corresponding calculation type, the core material information required by the calculation type, such as fuel, moderator, structural material, burnable poison and fission product, may be first selected in the present disclosure, and then the calculation is performed based on the core material information, which is not limited herein by the present disclosure.
It should be noted that, through the target core material information and the target calculation function information, the apparatus can select the required nuclide information to perform calculation according to the current calculation problem, that is, extract the corresponding cross section data file from the nuclide file corresponding to the current calculation problem to perform calculation.
And step 104, aggregating all the target section data files to generate a target section library.
After determining each target cross-sectional data file, each target cross-sectional data file may be merged to generate a database that may contain cross-sectional data of the target problem currently being solved.
It can be understood that the section data stored in the target section library can be used for the calculation of the current core design, and the calculation efficiency can be improved and the calculation load can be reduced because the section data is the section data file determined based on the target core material information and the target calculation function information.
As a possible implementation manner, the target cross-section library may be read by the core design software, and the target result corresponding to the target cross-section library is calculated and generated.
Specifically, the target cross-section library may be read and calculated by kernel design software based on a one-dimensional cell + component transport program or a geometric-section green's function program, and thus, a result corresponding to the target cross-section library, that is, a target result may be generated.
Note that the embodiment of the present disclosure does not limit the type of the core design software.
And 106, acquiring measured data of the nuclear power plant.
Specifically, the measured nuclear power plant data may be data of each dimension corresponding to the current target result, such as core power, boron concentration, control rod value, and the like, and many of them are not limited herein. The measured data of the nuclear power plant may be obtained by direct measurement through a sensor and an instrument, or may also be obtained through analysis. Therefore, the precision of the nuclear power plant reactor core during calculation can be improved, the calculation efficiency can be improved, and the calculation result is more reliable.
And step 107, correcting the section data file according to the actual measurement data and the target result of the nuclear power plant.
Specifically, after the measured data of the nuclear power plant is obtained, the nuclide information in the section data file can be corrected, wherein, since each section data file is independent, any specific section can be corrected conveniently and directly. Optionally, the target result and the measured data of the nuclear power plant may be combined to perform correction or comparison verification, which is not limited herein.
In the embodiment of the disclosure, basic information of each nuclide in a nuclide list is firstly acquired, then a nuclide file corresponding to each nuclide is determined according to the basic information of each nuclide, then at least one target section data file is extracted from the nuclide file corresponding to the target nuclide according to target core material information and target calculation function information, wherein the nuclide file comprises a plurality of section data files, then each target section data file is aggregated to generate a target section library, then a target result corresponding to the target section library is determined, then measured nuclear power plant data is acquired, and finally the section data file is corrected according to the measured nuclear power plant data and the target result. Therefore, the nuclide information required by calculation is stored in one data file, so that the time and resources for query search can be reduced, and the data files of all sections are independent, so that correction, comparison and verification can be facilitated, and the operation is facilitated.
Fig. 2 is a flowchart illustrating a method for generating a nuclear data cross-section library according to an embodiment of the disclosure.
As shown in fig. 2, the method for generating the nuclear data cross-section library may include the following steps:
in step 201, basic information of each nuclide in the nuclide list is acquired.
It should be noted that, for a specific implementation of step 201, reference may be made to the specific implementation process of the foregoing embodiment, which is not described herein again.
It should be noted that in some scenarios, for example, when performing simulation calculation on a self-powered detector used in a reactor, a key component in the self-powered detector simulation process is the distribution of neutrons and photons near the self-powered detector, and neutron and photon coupling transport solution based on a deterministic analysis method is usually required, so that if there are no photons and neutron data in basic information of nuclides, the calculation accuracy may be low. In some component power calculation containing burnable poison, because the power distribution difference is large, the power of a poison-containing grid cell is low, the weight of photon heat release on the influence of the power is large, and therefore accurate photon flux distribution is important for photon heat release calculation and burnable poison-containing component power calculation. Therefore, the neutron and photon data information can effectively improve the precision of calculation under some conditions of core and core design calculation.
The photon data information may include photon generation data and photon reaction cross section data, which are not limited herein.
The neutron data information may include burnup information, cross section information, resonance information, kinetic parameters, fission spectrum, trapped energy, and the like, which are not limited herein.
Each nuclide corresponds to its own central data information, and photon data information of isotopes in nuclides of the same element is the same.
It should be noted that by adding the photon data information and the neutron data information, more accurate photon flux distribution can be obtained when the detector and the component are released, so that the calculation precision of the nuclear power plant reactor core design can be higher.
The second basic information is a data set including basic information of nuclides in the nuclide list, photon data information and neutron data information.
And step 204, determining a nuclide file corresponding to each nuclide according to the second basic information of each nuclide.
It will be appreciated that from the second basic information for each species, a corresponding species file, i.e. a cross-sectional data set, for each species may be generated. The cross-section data set includes a plurality of independent files, such as a photon data file, an electronic data file, a middle data file, and the like, which are not limited herein.
And step 206, aggregating the target section data files to generate a target section library.
And step 208, acquiring measured data of the nuclear power plant.
And step 209, correcting the section data file according to the actual measurement data and the target result of the nuclear power plant.
It should be noted that, for specific implementation manners of steps 205, 206, 207, 208, and 209, reference may be made to the foregoing embodiments, and details are not described herein
In the embodiment of the disclosure, basic information of each nuclide in a nuclide list is first obtained, then photon data information and neutron data information corresponding to each nuclide are obtained, then the photon data information and the neutron data information corresponding to each nuclide are added into the basic information of each nuclide to generate second basic information of each nuclide, then a nuclide file corresponding to each nuclide is determined according to the second basic information of each nuclide, then at least one target section data file is extracted from the nuclide file corresponding to the target nuclide according to target reactor core material information and target calculation function information, wherein the nuclide file comprises a plurality of section data files, then each target section data file is aggregated to generate a target section library, then a target result corresponding to the target section library is determined, then measured data of a nuclear power plant is obtained, and finally the section data file is corrected according to the measured data of the nuclear power plant and the target result. Therefore, because the photon data and the neutron data are added, more accurate photon flux distribution can be obtained when the detectors and the components are calculated and released, the calculation result is more accurate, the accuracy of the nuclear power plant reactor core design calculation can be improved by correcting the section data file through the nuclear power plant measured data, and the calculation is more accurate.
