The first design may describe, for example, information such as a number range of components that may be used by the core, a fuel assembly arrangement, and the like, which is not limited. In some embodiments, the first design may be one or more (e.g., 10) schemes, and the number of generated first designs may be set by the user, which is not limited.

S104: the target design is determined from the first design based on the parameter value of the first parameter and the first parameter threshold.
Specifically, the core design system of the present embodiment may compare the parameter value of the first parameter with the first parameter threshold, and if the parameter value of the first parameter is within the first parameter threshold, it indicates that the design requirement is met, take the first design as the target design of the core, that is: and the user designs the core arrangement of the reactor according to the target design scheme.
When the generated first design schemes are multiple schemes, the parameter value of the first parameter in the calculation result of each first design scheme can be compared with the first parameter threshold value, and whether each first design scheme is the target design scheme or not can be judged.

The solution database module in the core design system of the embodiment of the disclosure may call a design solution library, which is used to store the historical design solution of the core, and may be a solution after detailed calculation.
Specifically, in the perturbation calculation process, the solution database module of the present embodiment may first query the design solution library for a similar historical design solution to the first design solution, and the similar historical design solution may be referred to as the second design solution. The second design may be obtained, for example, according to the text similarity between the first design and the history design, or may be obtained by any other possible manner, which is not limited. In the case where the first design is a plurality of designs, the corresponding second design may be obtained for each of the first designs, or an approximate second design may be obtained for all of the first designs, which is not limited thereto. An example of a second design approach to achieving an approximation will be described below.
Wherein, the historical design schemes stored in the design scheme library can be physically analyzed by the reactor, and each historical design scheme can have a neutron eigenvalue equation in a corresponding continuous or discrete form of transportation, which can be expressed as:
wherein the vector ψ is the generalized neutron fluence, k is the system effective gain value coefficient, M, S is the equation coefficient matrix, where ψ and k are solution variables, and the parameters of interest to the user can be deduced from ψ and k.
When a disturbance occurs in the system, equation (1) can be changed into the following form:
where Δ represents the amount of change, the following equation can be mathematically derived for a disturbance:
wherein ψ is a mathematical conjugate equation solution, which can be solved according to the related known quantity in equation (1).
Thus, for each historical design (including the second design) stored in the design library, there may be a corresponding known variable, including the equation coefficient matrices M and S, the conjugate equation solution ψ, and any other possible variable that may be used to perform perturbation calculations on the first design.
S304: an amount of difference in the second parameter in the first design and the second design is determined.
The difference amount in this embodiment may be referred to as a variation amount, and may be represented by Δm and Δs (see equation 3), for example, which may be obtained according to the second parameters corresponding to the generated first design scheme and the approximated second design scheme, that is: the difference amounts Δm and Δs are determined from the difference of the second parameter. In some embodiments, the second parameter may be, for example, a component cross-section parameter, wherein the user may specify a component type in the core design information, the component type determination may be the cross-section parameter, or the second parameter may be any other possible parameter, without limitation.
S305: and performing perturbation calculation based on the equation coefficient matrix, the conjugate equation solution and the difference quantity, and solving the reactor core reactivity coefficient of the first design scheme.
Specifically, the equation coefficient matrices M and S, the conjugate equation solution ψ, and the difference amounts Δm and Δs can be brought intoThe core reactivity coefficient may be obtained, and includes, for example, the generalized neutron fluence density ψ and the system effective gain value coefficient k.
S306: a parameter value of a third parameter of the first design is determined based on the core reactivity coefficient.
That is, after determining the generalized neutron fluence density ψ and the system effective gain value coefficient k, a third parameter focused by the user in the first design scheme may be derived according to ψ and k, where the third parameter in this embodiment may be, for example, the boron concentration.
S307: and screening the first design scheme according to the parameter value of the third parameter and the third parameter threshold value.
Specifically, the present embodiment may compare the parameter value of the third parameter (boron concentration) with the third parameter threshold (i.e., boron concentration threshold), may reserve the first design (scheme 1) for subsequent calculation if the boron concentration parameter value of the first design (scheme 1) satisfies the third parameter threshold, and delete the first design (scheme 2) if the boron concentration parameter value of the first design (scheme 2) does not satisfy the third parameter threshold. Therefore, the embodiment can perform preliminary screening on a plurality of first design schemes through perturbation calculation, and the first design schemes after screening pass the preliminary screening perform subsequent detailed calculation, so that calculation time required by calculation of the subsequent schemes is shortened.
In some embodiments, if the first design solution meeting the third parameter threshold does not exist after screening, namely: the first design is not all met with the third parameter threshold requirement, in which case the present embodiment may adjust the core design information and regenerate the first design. In practical applications, the control parameters in the core design information are mainly adjusted, and after the control parameters are adjusted, the first design scheme is regenerated.
Therefore, the embodiment can utilize the existing schemes subjected to detailed calculation in the scheme library to rapidly screen the first design schemes and screen valuable schemes to perform subsequent detailed calculation, so that each first design scheme can be prevented from being subjected to detailed calculation, and the time of detailed calculation is saved.
S308: and calculating the first design scheme to obtain a calculation result, wherein the calculation result comprises a parameter value of the first parameter.
S309: the target design is determined from the first design based on the parameter value of the first parameter and the first parameter threshold.
The descriptions of S308-309 are specifically referred to the above embodiments, and are not repeated here.
In some embodiments, the target design may also be stored in a design library as a historical design for use in screening subsequent designs.
In this embodiment, core design rules, component types, core component area information, control parameters and other core design information are obtained, a heuristic algorithm is adopted to calculate the core design information, a first design scheme of the core is generated, and a calculation result is obtained by calculating the first design scheme, wherein the calculation result comprises a parameter value of the first parameter, and a target design scheme is determined from the first design scheme according to the parameter value of the first parameter and a first parameter threshold value. Thus, a higher quality core design is provided for the nuclear power plant. In addition, the embodiment can utilize the existing schemes subjected to detailed calculation in the scheme library to rapidly screen the first design schemes and screen valuable schemes to perform subsequent detailed calculation, so that each first design scheme can be prevented from being subjected to detailed calculation, and the time of detailed calculation is saved.
