[0018] Example 1

[0019] The containment modeling data determination method provided in this application can be applied to the containment model establishment process before accident analysis in a severe accident calculation program for nuclear power plants. This containment modeling data determination method can be executed by a containment modeling data determination device, electronic equipment, and input card, etc. The following description uses the execution of this containment modeling data determination method by electronic equipment as an example.

[0020] like Figure 1 As shown, the method for determining containment modeling data provided in this application embodiment may include steps S110 to S150.

[0021] S110, acquire the basic data of the containment and a control body division mode, the basic data comprising n compartments, b initial flow channels and d initial thermal structures, the control body division mode comprising a correspondence between each of m containment control bodies and at least one compartment, n and m being positive integers, b and d being non-negative integers, and m≤n.

[0025] S150, determining containment modeling data of the containment according to the m sets of target control parameters, the c sets of target flow channel parameters and the e sets of target thermal structure parameters.

[0026] According to the containment modeling data determination method provided in the embodiments of the present application, the basic data of the containment and the control body division mode are first acquired; then, for each of the m containment control bodies, based on the control body division mode, the compartment parameters of a iThe compartment parameters of the compartments are merged to obtain target control body parameters of each containment control body, so as to obtain m groups of target control body parameters. Then, based on b groups of initial flow channel parameters corresponding to b initial flow channels in the containment, and the control body division mode, the b initial flow channels are merged to obtain c groups of target flow channel parameters corresponding to c target flow channels. Next, based on d groups of initial thermal structure parameters corresponding to d initial thermal structures in the containment, and the control body division mode, the d initial thermal structures are merged to obtain e groups of target thermal structure parameters corresponding to e target thermal structures. Then, the containment modeling data of the containment is determined according to the m groups of target control parameters, the c groups of target flow channel parameters and the e groups of target thermal structure parameters. In the whole process of determining the containment modeling data, no manual intervention is required, and the containment modeling data can be automatically determined, thereby improving the determination efficiency and accuracy of the containment modeling data.

[0027] The specific implementation of each step will be described below.

[0028] In step S110, the containment control body refers to a specific area or volume divided in the containment structure, which is used for thermodynamic and fluid dynamic calculation and analysis.

[0029] The control body division mode provided in the embodiments of the present application is shown in Table 1.

[0030] Table 1

[0031]

[0032]

[0033] It should be noted that the specific names in Table 1 are only for example and do not limit the present application. The number of compartments a corresponding to different containment control bodies i may be the same or different, which is not limited herein. For example, the containment control body CAV includes 3 compartments JR001-1, JR001-2 and JR001-3, the containment control body RPV-ROOM includes 2 compartments JR105 and JR205, and the containment control body PXS-VALVE includes 2 compartments JR100-4 and JR107.

[0034] For example, the control body division mode can be to allocate n compartments (RM1, RM2, …, RMn) to m control bodies (CV1, CV2, …, CVm). n ) to m control bodies (CV1, CV2, …, CV mThe control body division manner includes a corresponding relationship between each containment control body and at least one compartment in the m containment control bodies. The control body division manner can be pre-set in the electronic device by engineers according to experience. For example, some compartments can be combined into one containment control body according to the position of the containment control body and the associated equipment. More specifically, since the pressure vessel penetrates the three compartments JR001-1, JR001-2 and JR001-3, the three compartments JR001-1, JR001-2 and JR001-3 are divided into the same containment control body CAV.

[0035] In some embodiments, obtaining the basic data of the containment and the control body division manner further includes checking the basic data and the control body division manner, including:

[0036] checking the control body division manner;

[0037] checking the compartment parameters to obtain a first checking result;

[0038] checking the flow channel parameters to obtain a second checking result;

[0039] checking the thermal structure parameters to obtain a third checking result.

[0040] The checking of the control body division manner specifically includes:

[0041] all the compartments in the control body division manner are in the basic data of the containment;

[0042] the compartments contained in different containment control bodies cannot be repeated.

[0043] In some examples, the checking of the control body division manner further includes:

[0044] the control body name cannot exceed 16-bit strings.

[0045] The checking of the compartment, flow channel and thermal structure parameters is described in detail in steps S120, S130 and S140.

[0046] Exemplarily, the basic data of the containment and the control body division manner can be pre-stored in the electronic device for subsequent direct calling.

[0047] It should be noted that the values of n, b, c and m can be set according to actual conditions, which are not limited herein, for example, the value of n can be 112, the value of b can be 185, the value of c can be 97, and the value of m can be 40.

[0048] In step S120, after obtaining the basic data of the containment and the control volume division manner, the electronic device can further merge the compartment parameters of the a i compartment corresponding to each containment control volume i based on the control volume division manner to obtain the target control volume parameters of each containment control volume, so as to obtain m sets of target control volume parameters.

[0049] For example, before merging the compartment parameters of the a i compartment corresponding to each containment control volume i, the method can further include: obtaining the compartment parameters of each compartment of the a i compartment corresponding to each containment control volume. For example, the compartment parameters of each compartment of the n compartments are pre-stored in the electronic device, and after obtaining the control volume division manner, the compartment parameters of the a i compartment corresponding to each containment control volume i can be directly obtained from the data of the corresponding compartment in the n compartments of the containment basic data.

[0050] The following Tables 2-1 and 2-2 respectively give the parameter meaning explanation of the compartment and the control volume.

[0051] Table 2-1

[0053] Table 2-2

[0054]

[0055]

[0056] That is, the a i compartment assigned to the same containment control volume CV i (1≤i≤m) is merged, and the specific processing process will be introduced below.

[0057] For example, the compartment parameters of each compartment of the 112 compartments provided by the embodiments of the present application are shown in Tables 2-3 and 2-4.

[0058] Table 2-3

[0059]

[0060]

[0061] Table 2-4

[0062]

[0063] It should be noted that Table 2-3 and Table 2-4 constitute the compartment parameters of each of the 112 compartments, and the values in Table 2-3 and Table 2-4 are only for example and do not limit the present application. For example, the first initial bottom elevation of the compartment JR001-1 is -11.7m, the initial top elevation is -9.5m, the initial volume is 35.3m 2 , the initial water level, the initial flow area, the initial pressure, the initial gas temperature, the initial water temperature, the initial number of PARQX-75 compounders, the initial number of PARQX-150 compounders, the initial number of igniters, the initial boundary state marker, and the initial direction are all empty.

[0064] In some embodiments, a i compartment parameters of each of the 112 compartments include an initial compartment name, an initial bottom elevation, an initial top elevation, an initial volume, an initial water level, an initial flow area, an initial direction, an initial pressure, an initial gas temperature, an initial water temperature, an initial boundary state marker, p initial numbers of p kinds of hydrogen compounders, and an initial number of igniters, p is a non-negative integer;

[0065] The target control body parameters include a target control body name, a target elevation set Z i , a target volume set VR i , a target water level, a target pressure, a target gas temperature, a target water temperature, a target boundary state marker, p target numbers of p kinds of hydrogen compounders, and a target number of igniters; wherein the target elevation set Z i ={z i1 , z i2 , z i3 , …, z ix , …, z iax}, z i1 represents the first target elevation, z i2 represents the second target elevation; z iax represents the axth target elevation, and the target volume set VR i ={V i1 , V i2 , V i3 , …, V ix , …, V iax}, V i1 =0, V i2 represents the target volume between the target elevation z i1 and the target elevation z i2 , V ix represents the target volume between the target elevation z ix-1 and the target elevation z ix , and V iax represents the target volume between the target elevation z iaxand target elevation z iax The target volume between;

[0066] Based on the control body partitioning method, for each containment control body i, the corresponding a i The compartment parameters of each compartment are merged to obtain the target control body parameters for each containment control body, including:

[0067] If the first check passes, extract a. i Each compartment corresponds to a i The zeroth elevation set Z0 is obtained by taking all the initial bottom and top elevations from the parameters of each compartment and removing duplicates among them. i Among them, Z0 i ={z0 i1 z0 i2 z0 i3 , ..., z0 iax}, z0 i1 Indicates the first zeroth elevation, z0 i2 Indicates the second zeroth elevation; z0 iax Let x represent the zeroth elevation of the x-th element, where x is a positive integer;

[0068] For the zeroth standard high set Z0 i Sort all zeroth elevations in the data to obtain the target elevation set Z. i ;

[0069] Regarding a i RM in any of the compartments ij The initial volume in the corresponding compartment parameters is converted into the target elevation set Z. i The corresponding first volume set VR ij , to obtain a i The first volume set VR ij VR ij ={v(i,j)1,v(i,j)2,…,v(i,j) ax Let v(i,j)1 represent the first volume, and v(i,j)1=0, v(i,j) x | ax≥x>1 Indicates the target elevation z ix- and target elevation z ix The first volume between, RM ij ∈R i , 1≤j≤a i R i Represents a set of compartments;

[0070] According to a i The first volume set VR ijDetermine the target volume set VR of the containment control body. i ;

[0071] a i The maximum value of all initial water levels in the parameters of the compartments containing water is determined as the target water level of the containment control body.

[0072] For each of the p types of hydrogen recombiners, q, a i Among the parameters of each compartment, the type of the compositer q corresponds to a. i The sum of the initial number of recombiners is used to determine the target number of recombiners of type q in the containment control body, so as to obtain the p target number of recombiners corresponding to the p types of hydrogen recombiners in the containment control body.

[0073] a i The sum of the initial igniters in each compartment parameter is used to determine the target igniter number for the containment control body.

[0074] Understandably, the RM cubicle ij In the text, j represents the compartment number; the compartment containing water is the compartment whose initial water level is higher than the bottom elevation.

[0075] It should be noted that the target control volume parameters also include the target control volume name, target pressure, target air temperature, target water temperature, and target boundary state markers. The target control volume name, target pressure, target air temperature, target water temperature, and target boundary state markers can all be set according to actual conditions, and are not limited here.

[0076] In this embodiment, based on the above-described implementation method, the target control body parameters of the containment control body can be automatically determined, providing a basis for the subsequent automatic determination of containment modeling data.

[0077] In some implementations, obtaining the first inspection result specifically includes:

[0078] According to the preset partition requirements, a i Check the compartment parameters of each room;

[0079] In a i If the partition parameters of each partition in each compartment meet the preset partition requirements, the first inspection result is determined to be passed.

[0080] or,

[0081] In a i If at least one of the compartments does not meet the preset compartment requirements, the first inspection result is determined to be unsuccessful.

[0082] In this embodiment, a is determined according to the preset compartment requirements. iThe compartment parameters of each compartment were checked to prepare for subsequent checks on the corresponding a of the containment control body. i The compartment parameters of each compartment in the containment control body are merged to provide a basis for obtaining the target control body parameters of the containment control body, and can improve the accuracy of the target control body parameters.

[0083] In some examples, the default compartment requirements include:

[0084] The initial top elevation is greater than the initial bottom elevation;

[0085] The initial water level is between the initial bottom elevation and the initial top elevation;

[0086] Except for the initial compartment name, all other parameters in the compartment parameters are numerical values;

[0087] a i All initial pressures, initial air temperatures, and initial boundary state markings are identical across all compartments, and the water temperature is identical across all compartments containing water. The water temperature of compartments without water (i.e., water level = bottom elevation) is ignored.

[0088] In other words, in the embodiments of this application, for a i The compartment parameters of each compartment in each compartment are checked, including: a) the initial top elevation is greater than the initial bottom elevation; the initial water level is between the initial bottom elevation and the initial top elevation; the initial bottom elevation, initial top elevation, initial volume, initial water level, initial flow area, initial direction, initial pressure, initial air temperature, initial water temperature, initial boundary state marking, the number of p initial recombiners corresponding to p types of hydrogen recombiners, and the number of initial igniters must be numerical values; b) the merged a i The initial pressure, initial air temperature, initial water temperature (when water is present), and initial boundary state markings of each compartment must be identical. When there is no water in a compartment, i.e., the initial water level equals the initial bottom elevation, the water temperature of that compartment can be ignored during merging; c) Merging a i When the initial flow area and initial direction of each compartment are the same, the same parameter is retained. However, when the initial flow area and initial direction are different, the compartments can still be merged, but the initial flow area and initial direction are deleted. After deletion, the initial flow area and initial direction are calculated in the default way, and a warning message indicating that the initial flow area and initial direction are inconsistent can also be output.

[0089] In some examples, the default compartment requirements also include:

[0090] The values ​​of initial volume, initial flow area, initial pressure, initial air temperature, and initial water temperature must be greater than zero;

[0091] The number of p initial recombiners corresponding to each of the p types of hydrogen recombiners, and the number of initial igniters must be no less than zero.

[0092] The initial direction must be 1 (representing horizontal) or 2 (representing vertical).

[0093] In this example, by setting the above preset compartment requirements, the accuracy of the target control body parameters can be further improved.

[0094] In some examples, the preset compartment requirements further include using default values instead when the initial water level, initial flow area, initial direction, initial pressure, initial air temperature, initial water temperature, initial boundary state marker, p initial compounder quantities, and initial igniter quantity are not provided in the basic data, i.e., using default settings for the above parameters, i.e.:

[0095] The initial water level = the initial bottom elevation;

[0096] The initial flow area = the initial volume ÷ (the initial top elevation - the first initial bottom elevation);

[0097] The initial direction = 2;

[0098] The initial pressure = the containment global atmospheric pressure;

[0099] The initial air temperature = the containment global atmospheric temperature;

[0100] The initial water temperature = the air temperature of the same compartment;

[0101] The initial boundary state marker is 0;

[0102] The p initial type quantities are all 0;

[0103] The initial igniter quantity is 0.

[0104] Exemplarily, the containment global atmospheric pressure is 1 bar, and the containment global atmospheric temperature is 50°C. In order to simplify or facilitate input, so as not to input the initial temperature and initial pressure for all compartments, compartment derivative parameters can be set, including the containment global atmospheric pressure 1 bar and the containment global atmospheric temperature 50°C. That is, using default values, only special compartments need to be input when the containment global atmospheric pressure and the containment global atmospheric temperature are different. In the merger of a i When merging the parameters of the compartments, the compartment derivative parameters do not need to be checked. The initial pressure and the initial temperature of all compartments can also be set as default values, thereby omitting parameter input.

[0105] In this example, by setting the above preset compartment requirements, the demand for necessary parameters of the basic data can be simplified, and the input quantity is reduced.

[0106] Exceptions can also exist, for example, the initial bottom elevation and the initial top elevation can be replaced by the initial bottom elevation and the initial height, etc.

[0107] It should be noted that if the first test result is a failure, a message indicating that the compartment parameters failed can be output to remind the user which parameters in which compartments failed the check, facilitating the user's location and correction of the error. After the user modifies the basic data, the user needs to return to the step of obtaining the basic containment data to re-establish the corresponding 'a' for the containment control body. i The compartment parameters of each compartment in each of the a compartments are then checked, and the compartment parameters of each compartment in the a compartments corresponding to the containment control body are then checked.

[0108] It should be noted that, in the embodiments of this application, both the zeroth elevation and the first elevation include the bottom elevation and the top elevation.

[0109] For example, the zeroth elevation set Z0 can be... i Sort all zeroth elevations in the data from smallest to largest to obtain the target elevation set Z. i It can also be applied to the zeroth elevation set Z0. i Sort all zeroth elevations in the data from largest to smallest to obtain the target elevation set Z. i In other words, the target elevation set Z i The target elevations within the area can be in an increasing or decreasing sequence.

[0110] In some examples, it is converted into a target elevation set Z. i The corresponding first volume set VR ij ,include:

[0111] Get the compartment RM ij The first elevation set Z ij Z ij ={zr ij1 ,zr ij2}, zr ij1 This indicates the first elevation, representing the compartment RM. ij The bottom elevation, zr ij2 This indicates the second first elevation, representing the compartment RM. ij The top elevation;

[0112] For the first standard high set Z ij For each first elevation, determine the target elevation set Z. i The elevation position z that is equal to the first elevation value is , z it , where 0≤s <t≤ax,z is =zr ij1 , z it =zr ij2 ;

[0113] According to the corresponding elevation position of the target elevation set, the initial volume v ij of the compartment RM ij is converted into the first volume set VR ij , where v(i,j) x is 0 when x≤s or t<x, and the initial volume v ij of the compartment RM ij is distributed according to the height ratio between each target elevation when s<x≤t,

[0114] In this example, a i initial volume of a i compartment parameter corresponding to a i compartment can be converted into the corresponding first volume set VR i of the target elevation set Z ij by the above process, providing a basis for subsequent merging of the target volume of the containment control body.

[0115] It should be noted that a i compartment forms a compartment set R i , where, RM i1 represents the first compartment, RM i2 represents the second compartment, and RM i represents the a i compartment. Exemplarily, the target volume set VR i of the containment control body CV i1 = {V i2 , V iax , …, V i} corresponds to the target elevation in the target elevation set Z i1 = {z i2 , z i3 , z ix , …, z iax}, where V i1 = 0, V ix represents the target volume between the target elevation z ix-1 and the target elevation z ix , and 1<x≤ax. The target volume set VR i = {V i1 , V i2 , V i3 , …, V iax} is a i first volume set VR i corresponding to a ij compartment contained therein.={v(i,j)1,v(i,j)2,…,v(i,j) ax The sum of the first volumes of the same target elevation in}, i.e. It should be noted that if any V exists ix =0 indicates that the control volume is discontinuous, which means that there is an error in the control volume partitioning method.

[0116] For example, the containment control body CV i Target water level L i Take a i The initial water level (Lw) in each compartment containing water. i1 , The maximum value in ) means that the initial water level of the compartment containing water should be greater than the bottom elevation of that compartment, ignoring the initial water level of compartments without water (i.e., water level = bottom elevation). However, when the initial water level of any compartment is Lw x <L i (1≤x≤a i And Lw x >zr ij1 When ), Lw must be satisfied. x =zr ij2 Otherwise, it indicates an unreasonable situation where there is an air space below the water level of the control body, which means that there is an error in the control body division method or an error in the database.

[0117] For example, the containment control body CV i The number of compositer types q (i.e., the number of target compositers) nq i For a i The number of composite device types q in each compartment The sum, that is

[0118] For example, target volume set VR i For its included a i The first volume of the compartment VR ij The sum of the first volumes of targets at the same elevation, i.e.

[0119] For example, the target control volume parameters may also include target water temperature, target flow area, target direction, and target boundary status markers.

[0120] Taking 52 target control entities as an example, examples of target control entity parameters in this application embodiment are shown in Tables 3-1 and 3-2.

[0123] Table 3-2

[0124]

[0125] It should be noted that the values of Table 3-1 and Table 3-2 are only for example and do not limit the present application. The target control body name and the target control body number can be set according to actual conditions, which are not limited herein. For example, the target control body name is CAV, the target number is 1, the target pressure is 0.1, the target gas temperature is 323, the target water temperature is 323, the target water level is 11.7, the target flow area is empty, the target direction is horizontal, the target boundary state marker is empty, the target PARQX-75 compounder number (i.e. the target compounder number corresponding to the hydrogen compounder type), the target PARQX-75 compounder (i.e. the target compounder number corresponding to the hydrogen compounder type) number, the target igniter number are all 0, the target elevation 1 is -11.7, the target volume 1 is 0, the target elevation 2 is -9.5, the target volume 2 is -35, the target elevation 3 is -6.7, the target volume 3 is -5.0, the target elevation 4 is -4.5, and the target volume is -41.

[0126] In step S130, after obtaining the m groups of target control body parameters, the electronic device can further merge the b initial flow channels based on the b groups of initial flow channel parameters corresponding to the b initial flow channels in the containment vessel and the control body division mode, to obtain c groups of target flow channel parameters corresponding to the c target flow channels.

[0127] For example, the electronic device can pre-store the b groups of initial flow channel parameters corresponding to the b initial flow channels in the containment vessel, so as to be directly called subsequently.

[0128] The following Tables 4-1 and 4-2 respectively give the parameter meaning of the inter-compartment flow channel and the inter-control body flow channel.

[0134] For example, the initial flow channel parameters provided by the embodiments of the present application are shown in Table 4-3 and Table 4-4. The value of b can be set according to actual conditions, which is not limited herein.

[0139] Table 4-4

[0140]

[0141]

[0142] It should be noted that Table 4-3 and Table 4-4 constitute the initial flow passage parameters of 185 initial flow passages, and the values in Table 4-3 and Table 4-4 are only for example and do not limit the present application. For example, the initial flow passage with the initial flow passage name JR001-1 to JR105, the initial upstream compartment name JR001-1, the initial downstream compartment name JR105, the initial upstream opening elevation -9.5m, the initial downstream opening elevation -8m, the initial flow area 0.66m2, the initial opening length 0.46m, the initial opening width 0.46m, the initial flow passage length 4.00m, the initial flow passage direction horizontal direction, and the initial opening state open. 2

[0143] In some embodiments, the initial flow passage parameters include the initial flow passage name, the initial upstream compartment name, the initial downstream compartment name, the initial upstream opening elevation, the initial downstream opening elevation, the initial opening length, the initial opening width, the initial flow area, the initial flow passage length, the initial flow passage direction, and the initial opening state.

[0144] Based on the b sets of initial flow passage parameters corresponding to the b initial flow passages in the containment, and the control body division mode, the b initial flow passages are merged to obtain c sets of target flow passage parameters corresponding to the c target flow passages, including:

[0145] For each of the b initial flow passages, the initial upstream compartment name is replaced by the containment control body name corresponding to the upstream compartment name, and the initial downstream compartment name is replaced by the containment control body name corresponding to the initial downstream compartment name.

[0146] ​In a case where the second checking result is passed, the initial flow passage with the same initial upstream containment control body name and the initial downstream containment control body name is deleted, to obtain h first intermediate flow passages, h≤b, and h is a non-negative integer; the parameters of the first intermediate flow passage include a first flow passage name, a first upstream containment control body name, a first downstream containment control body name, a first upstream opening elevation, a first downstream opening elevation, a first opening length, a first opening width, a first flow area, a first flow passage length, a first flow passage direction, and a first opening state;

[0147] For the first intermediate flow passage, all the first intermediate flow passages with the same upstream and downstream containment control body names are adjusted to have the same flow direction, to obtain h second intermediate flow passages. The parameters of the second intermediate flow passage include a second flow passage name, a second upstream containment control body name, a second downstream containment control body name, a second upstream opening elevation, a second downstream opening elevation, a second opening length, a second opening width, a second flow area, a second flow passage length, a second flow passage direction, and a second opening state;

[0148] For the second intermediate flow passage, the second intermediate flow passages with the same characteristic parameters are merged to obtain c target flow passages and c sets of target flow passage parameters corresponding to the target flow passages; the target flow passage parameters include a target flow passage name, a target upstream containment control body name, a target downstream containment control body name, a target upstream opening elevation, a target downstream opening elevation, a target opening length, a target opening width, a target flow area, a target flow passage length, a target flow passage direction, and a target opening state.

[0149] In the embodiment, through the above manner, the c sets of target flow passage parameters can be automatically determined, to provide a basis for subsequent automatic determination of containment modeling data.

[0150] Exemplarily, the upstream compartment name of the initial flow passage JR001-1-JR001-2 is JR001-1, and the downstream compartment name is JR001-2, the upstream compartment name JR001-1 is replaced by the containment control body CAV to which the upstream compartment name JR001-1 belongs, and the downstream compartment name JR001-2 is replaced by the containment control body CAV to which the downstream compartment name JR001-2 belongs. That is, the initial upstream containment control body name of the initial flow passage JR001-1-JR001-2 is CAV, and the initial downstream containment control body name is CAV.

[0151] In some examples, the obtaining of the second checking result specifically includes:

[0152] The b sets of initial flow passage parameters corresponding to the b initial flow passages are checked according to preset flow passage requirements;

[0153] In a case where the b sets of initial flow channel parameters corresponding to the b initial flow channels all meet the preset flow channel requirements, it is determined that the second checking result is passed.

[0154] Or,

[0155] In a case where at least one of the b sets of initial flow channel parameters corresponding to the b initial flow channels does not meet the preset flow channel requirements, it is determined that the second checking result is failed.

[0156] In the embodiment, the b sets of initial flow channel parameters corresponding to the b initial flow channels are checked according to the preset flow channel requirements, which provides a basis for subsequent merging of the b initial flow channels and improves the accuracy of the c sets of target flow channel parameters.

[0157] In some examples, the preset flow channel requirements include:

[0158] The initial flow channel parameters other than the initial flow channel name, the initial upstream compartment name and the initial downstream compartment name are numerical values.

[0159] That is, the initial upstream opening elevation, the initial downstream opening elevation, the initial opening length, the initial opening width, the initial flow area, the initial flow channel length, the initial flow channel direction and the initial opening state must be numerical values. The initial opening length, the initial opening width, the initial flow area and the initial flow channel length must be greater than 0. The initial opening state must be 0 or 1.

[0160] In some examples, the preset flow channel requirements include:

[0161] The initial opening state represents the opening share in the interval [0, 1]. When the initial opening state is greater than or equal to 1, it indicates that the initial flow channel is completely open, and is reset to 1 during checking. Warning information can be given at the same time. When the initial opening state is less than or equal to 0, it indicates that the initial flow channel is completely closed, and is reset to 0 during checking. Warning information can be given at the same time.

[0162] In the example, by setting the above preset flow channel requirements, the accuracy of the target flow channel parameters can be further improved.

[0163] In some examples, the preset flow channel requirements include: an initial upstream opening elevation, which can be referred to as an initial upstream elevation in short, and an initial downstream opening elevation, which can be referred to as an initial downstream elevation in short. An initial opening length can be a corresponding height when the opening is vertical. When the initial opening length ≠ the initial opening width, the flow channel opening is rectangular, and when the initial opening length = the initial opening width, the flow channel opening is circular. An initial flow direction can include one of a horizontal direction, a vertical direction, a unidirectional forward horizontal direction, a unidirectional forward vertical direction, a unidirectional reverse horizontal direction, and a unidirectional reverse vertical direction, wherein the forward direction refers to a flow from an upstream compartment to a downstream compartment, and the reverse direction refers to a flow from the downstream compartment to the upstream compartment. An initial opening state represents an opening share of the flow channel, and an actual flow area of the flow channel = an initial flow area * the initial opening state.

[0164] For example, for a square hole with a side length of 5 cm, an initial opening length of 5.001 cm and an initial opening width of 5 cm can be set, so that the opening shape is identified by setting the initial opening length ≠ the initial opening width, without the need for additional definition of the opening shape, thereby reducing the number of input parameters.

[0165] In some examples, the preset flow channel requirements further include that, when the initial flow area, the initial flow direction, and the initial opening state are not provided in the basic data, default values are used instead, i.e., the above-mentioned parameters are set by default, namely:

[0166] The initial flow area = a unit flow area of the initial flow channel;

[0167] The initial flow direction = 0;

[0168] The initial opening state = 1.

[0169] That is, the default initial flow area = a unit flow area of the initial flow channel; the initial flow direction defaults to the horizontal direction; and the initial opening state defaults to full opening.

[0170] In some examples, the preset flow channel requirements further include that, when only one of the initial upstream opening elevation and the initial downstream opening elevation is provided in the basic data, the initial upstream opening elevation and the initial downstream opening elevation are defaulted to be equal; and when only one of the initial opening length and the initial opening width is provided, the initial opening length and the initial opening width are defaulted to be equal, namely:

[0171] The initial upstream opening elevation = the initial downstream opening elevation (when only the initial downstream opening elevation is provided);

[0172] The initial downstream opening elevation = the initial upstream opening elevation (when only the initial upstream opening elevation is provided);

[0173] The initial opening length = the initial opening width (when only the initial opening width is provided);

[0174] Initial opening width = initial opening length (when only initial opening length is provided).

[0175] Exemplarily, the flow channel derivation parameters can also be provided in the electronic device, and the flow channel derivation parameters include opening height, unit flow area, wet perimeter, and parallel flow channel number. For a horizontal flow channel, the opening height = initial opening length; for a vertical flow channel, the opening height = 0.01 m by default; the unit flow area = π*initial opening length 2 / 4 (for a circle) or initial opening length*initial opening width (for a square); the wet perimeter = π*opening length (for a circle) or 2*(initial opening length+initial opening width) (for a square); and the parallel flow channel number = initial flow area / unit flow area.

[0176] In the present example, by providing the above preset flow channel requirements, the demand for necessary parameters of the basic data can be simplified, and the input quantity can be reduced.

[0177] It should be noted that the flow channel derivation parameters are required for modeling, but are not checked during merging. The initial opening length and the initial opening width are checked during merging, and the new flow area after merging will determine the derivation parameters again. The unit flow area and the wet perimeter after merging will not change, but the parallel flow channel number will change due to the change of the total flow area.

[0178] It should be noted that in the case where the second check result is not passed, an initial flow channel parameter error prompt information can be output to prompt the user which parameters of which initial flow channels do not meet the preset flow channel requirements, so as to facilitate the user to locate the error position and modify the error. After the user modifies, the user needs to return to the step of obtaining the basic data of the containment vessel again to obtain b sets of initial flow channel parameters corresponding to the b initial flow channels in the containment vessel, and then check the b sets of initial flow channel parameters corresponding to the b initial flow channels in the containment vessel.

[0179] Exemplarily, still taking the initial flow channels JR001-1-JR001-2 as an example, the upstream containment vessel control body name is CAV, and the downstream containment vessel control body name is CAV, that is, the upstream containment vessel control body name and the downstream containment vessel control body name of the initial flow channels JR001-1-JR001-2 are the same, that is, JR001-1-JR001-2 is a flow channel located inside the containment vessel control body CAV, and the initial flow channels JR001-1-JR001-2 are deleted.

[0180] Exemplarily, all the first intermediate flow channels having the same upstream and downstream containment vessel control body names are adjusted to have the same flow direction, including:

[0181] For any one of the h intermediate flow channels X, among the remaining h-1 intermediate flow channels, if there exists a case where the name of the first upstream containment control body of the first intermediate flow channel Y is the same as the name of the first upstream containment control body of the first intermediate flow channel X, and the name of the first downstream containment control body of the first intermediate flow channel Y is the same as the name of the first downstream containment control body of the first intermediate flow channel X; or, if there exists a case where the name of the first upstream containment control body of the first intermediate flow channel Y is the same as the name of the first downstream containment control body of the first intermediate flow channel X, and the name of the first downstream containment control body of the first intermediate flow channel Y is the same as the name of the first upstream containment control body of the first intermediate flow channel X, then it is determined that the first intermediate flow channel X and the first intermediate flow channel Y have the same upstream and downstream containment control body names; if the first intermediate flow channel Y... k The upstream containment control body name is the same as the downstream containment control body name of the first intermediate flow channel X, and the first intermediate flow channel Y... k If the name of the downstream containment control body is the same as the name of the upstream containment control body of the first intermediate flow channel X, then the name of the first intermediate flow channel Y will be changed. k The name of the second upstream containment control body is updated to the name of the first upstream containment control body of the first intermediate channel X, and the name of the first intermediate channel Y is changed. k The name of the second downstream containment control body is updated to the name of the first downstream containment control body of the first intermediate channel X, and the name of the first intermediate channel Y is changed. k The elevation of the second upstream opening is updated to the first intermediate flow channel Y. k The elevation of the first downstream opening, and the first intermediate flow channel Y k The elevation of the second downstream opening is updated to the first intermediate flow channel Y. k The first upstream opening elevation, the updated first intermediate channel Y k Called the second intermediate flow channel Y′ k The parameters of the remaining second intermediate channels that have not been updated are the same as before the update, resulting in h second intermediate channels; where {Y1, Y2, ..., Y... K} is the set of all first intermediate channels Y that have the same upstream and downstream containment control body names as the first intermediate channel X. k ∈{Y1, Y2, ..., Y K}, 1≤k≤K.

[0182] For example, merging second intermediate flow channels with the same characteristic parameters yields c target flow channels, including: for any second intermediate flow channel X′ among h second intermediate flow channels, in the remaining h-1 second intermediate flow channels, if there exists a second intermediate flow channel Y′ whose second upstream containment control body name, second downstream containment control body name, second upstream opening elevation, second downstream opening elevation, second opening length, second opening width, second flow channel length, second flow channel direction, and second opening state are all the same as those of the second intermediate flow channel X′, then it is determined that the second intermediate flow channel Y′ has the same characteristic parameters as the second intermediate flow channel X′; for any second intermediate flow channel X′ among h second intermediate flow channels, {Y′1, Y′2, Z′3, ..., Y′...} K} is the set of all second intermediate flow channels Y′ that have the same characteristic parameters as the second intermediate flow channel X′, Y′ k ∈{Y′1, Y′2, z′3,…,Y′ K If 1≤k≤K, then the second intermediate flow channel X′ and all second intermediate flow channels {Y′1, Y′2, Z′3, ..., Y′} will be connected. k The target flow channel C is merged into a single target flow channel C. The target flow channel C has the same target flow channel name, target upstream containment control body name, target downstream containment control body name, target upstream opening elevation, target downstream opening elevation, target opening length, target opening width, target flow channel length, target flow channel direction, and target opening state as the second upstream containment control body name, second downstream containment control body name, second upstream opening elevation, second downstream opening elevation, second opening length, second opening width, second flow channel length, second flow channel direction, and second opening state as the second intermediate flow channel X′. The target flow area of ​​the target flow channel C is the sum of the target flow areas of all the second intermediate flow channels {X′, Y′1, Y′2, Z′3, ..., Y′...}. K The sum of the second flow areas of} yields c target flow channels and c sets of target flow channel parameters corresponding one-to-one with the c target flow channels, where c is a non-negative integer.

[0183] Taking the merged c of the embodiments of this application as an example, the multiple sets of target flow channel parameters provided in the embodiments of this application are shown in Table 5.

[0184] Table 5

[0185]

[0186]

[0187] It should be noted that the names and values in Table 5 are only for example, and do not limit the present application. For example, the target flow channel with the name of 1CAV-RPV-R has a target flow channel number of 801, a target upstream containment control body number of 801, a target downstream containment control body number of 802, a target upstream opening elevation of -9.5, a target downstream opening elevation of -8, a target opening height of 0.01, a target flow area of 0.66, a target flow channel length of 4, a target hydraulic diameter of 0.46, a target flow channel direction of 0, and a target opening state of 1.

[0188] In step S140, after obtaining the c sets of target flow channel parameters, the electronic device can further merge the d initial thermal structures based on the d sets of initial thermal structure parameters corresponding to the d initial thermal structures in the containment, and the control body division mode, to obtain e sets of target thermal structure parameters corresponding to e target thermal structures.

[0189] For example, the electronic device can pre-store the d sets of initial thermal structure parameters corresponding to the d initial thermal structures in the containment, so as to be directly called subsequently.

[0198] For example, the initial thermal structure parameters provided by the embodiments of the present application are shown in Tables 6-3 and 6-4.

[0202] Table 6-4

[0203]

[0204]

[0205] It should be noted that Table 6-3 and Table 6-4 constitute the initial thermal structure parameters of 214 initial thermal structures, and the values in Table 6-3 and Table 6-4 are only for example and do not limit the present application. For example, the initial thermal structure name JR001-1B, the initial left adjacent compartment name JR001-1, the initial right adjacent compartment name ENVI, the initial shape parameter 2, the initial net surface area 27.43m 2 , the initial lowest point elevation -15.2m, the initial height 4m, the initial concrete thickness 3.5m, the initial lining thickness, the initial L-face paint thickness, the initial R-face paint thickness, the initial air gap thickness and the initial liquid film continuity marker are all empty.

[0206] In some embodiments, the initial thermal structure parameters include the initial thermal structure name, the initial left adjacent compartment name, the initial right adjacent compartment name, the initial shape parameter, the initial direction parameter, the initial net surface area, the initial lowest point elevation, the initial height, the initial concrete thickness, the initial lining thickness, the initial lining position, the initial L-face paint thickness, the initial R-face paint thickness, the initial air gap thickness and the initial liquid film continuity marker;

[0207] Based on the d sets of initial thermal structure parameters corresponding to the d initial thermal structures in the containment, and the control body division mode, the d initial thermal structures are merged to obtain e sets of target thermal structure parameters corresponding to e target thermal structures, including:

[0208] For each of the d initial thermal structures, the initial left adjacent compartment name is replaced by the containment control body name corresponding to the left adjacent compartment name to obtain the initial left containment control body name, and the initial right adjacent compartment name is replaced by the containment control body name corresponding to the initial right adjacent compartment name to obtain the initial right containment control body name;

[0209] In the case where the third check result is passed, the d group of initial thermal structure parameters are preprocessed to obtain d group of preprocessed first intermediate thermal structure parameters, the preprocessed first intermediate thermal structure parameters include a first thermal structure name, a first left side adjacent control body name, a first right side adjacent control body name, a first shape parameter, a first direction parameter, a first net surface area, a first lowest point elevation, a first height, a first concrete thickness, a first lining thickness, a first lining position, a first L face paint thickness, a first R face paint thickness, a first air gap thickness and a first liquid film continuity mark;

[0210] For any first intermediate thermal structure A1 in the d first intermediate thermal structures, there is at least one first intermediate thermal structure B1 in the remaining d-1 first intermediate thermal structures i In the case where the preset merging condition is met, the first intermediate thermal structure A1 and the at least one first intermediate thermal structure B1 i are merged into a second intermediate thermal structure A2 to obtain d2 second intermediate thermal structures, e≤d2

[0211] For any second intermediate thermal structure A2 in the d2 second intermediate thermal structures, there is at least one second intermediate thermal structure B2 in the remaining d2-1 second intermediate thermal structures i In the case where the preset merging condition is met, the second intermediate thermal structure A2 and the at least one first intermediate thermal structure B2 i are merged into a third intermediate thermal structure A3 to obtain d3 third intermediate thermal structures, e≤d3

[0212] The above steps are repeated to obtain dN intermediate Nth thermal structures, for any intermediate Nth thermal structure AN of the dN intermediate Nth thermal structures, if there is no intermediate Nth thermal structure BN of the remaining dN-1 intermediate Nth thermal structures that satisfies the preset merging condition, then the thermal structure merging ends, e target thermal structures are obtained, and e sets of target thermal structure parameters corresponding to the e target thermal structures are obtained, e = dN, and e, dN and N are non-negative integers; the target thermal structure parameters include a target thermal structure name, a target left-side adjacent control body name, a target right-side adjacent control body name, a target shape parameter, a target direction parameter, a target net surface area, a target lowest point elevation, a target height, a target concrete thickness, a target lining thickness, a target lining position, a target L-face paint thickness, a target R-face paint thickness, a target air gap thickness and a target liquid film continuity marker.

[0213] That is, for any intermediate N-1th thermal structure A(N-1) of the d(N-1) intermediate N-1th thermal structures, if there is at least one intermediate N-1th thermal structure B(N-1) i that satisfies the preset merging condition among the remaining d(N-1)-1 intermediate N-1th thermal structures, the intermediate N-1th thermal structure A(N-1) and the at least one intermediate N-1th thermal structure B(N-1) i are merged into an intermediate Nth thermal structure AN to obtain dN intermediate Nth thermal structures, e ≤ dN < d(N-1), and dN is a non-negative integer. Exemplarily, the initial lining thickness is the initial steel material thickness, the initial L-face paint thickness is the paint thickness of the left side surface, the initial R-face paint thickness is the paint thickness of the right side surface, and the initial air gap thickness is the thickness of the air gap between the concrete and the steel lining.

[0214] Exemplarily, the initial left-side adjacent compartment name of the initial thermal structure JR571-JR505 is JR571, and the initial right-side adjacent compartment name is JR505, the initial left-side adjacent compartment name JR571 is replaced by the containment control body STAIR2 to which the initial left-side adjacent compartment name JR571 belongs, and the initial right-side adjacent compartment name JR505 is replaced by the containment control body SPACE1-IN to which the initial right-side adjacent compartment name JR505 belongs. That is, the initial left-side adjacent containment control body name of the initial thermal structure JR571-JR505 is STAIR2, and the initial right-side adjacent containment control body name is SPACE1-IN.

[0215] In some examples, the obtaining of the third check result specifically includes:

[0216] checking the d sets of initial thermal structure parameters corresponding to the d initial thermal structures in the containment according to preset thermal structure requirements;

[0217] In a case where the d groups of initial thermal structure parameters corresponding to the d initial thermal structures in the containment vessel all satisfy the preset thermal structure requirement, the third check result is determined to be passed;

[0218] Or, in a case where at least one group of initial thermal structure parameters corresponding to the d initial thermal structures in the containment vessel does not satisfy the preset thermal structure requirement, the third check result is determined to be failed.

[0219] In the embodiment, the d groups of initial thermal structure parameters are subjected to the preset thermal structure requirement, so that the accuracy of the d groups of initial thermal structure parameters is improved, and the accuracy of the e groups of target thermal structure parameters determined subsequently is further improved.

[0220] In some examples, the preset thermal structure requirement includes:

[0221] Except for the initial thermal structure name, the initial left adjacent compartment name, the initial right adjacent compartment name and the initial liquid film continuity mark, other parameters must be numerical values. That is, the initial shape parameter, the initial direction parameter, the initial net surface area, the initial lowest point elevation, the initial height, the initial concrete thickness, the initial lining thickness, the initial L-face paint thickness, the initial R-face paint thickness and the initial air gap thickness must be numerical values. The initial direction parameter must be 1 or 2 or -2, the initial net surface area and the initial height must be greater than 0, and the initial concrete thickness, the initial lining thickness, the initial L-face paint thickness, the initial R-face paint thickness and the initial air gap thickness must be greater than or equal to 0;

[0222] In a case where the initial shape parameter is 0, i.e., the thermal structure shape is a flat plate, the initial net surface area cannot be null;

[0223] The sum of the initial concrete thickness and the initial lining thickness must be greater than 0, i.e., at least one of them is not zero. That is, the initial concrete thickness ≠ 0, indicating that the initial thermal structure body is a concrete structure; the initial concrete thickness = 0 and the initial lining thickness ≠ 0, indicating that the initial thermal structure is one of a steel plate, a steel pipe and a steel containment vessel, and the material of the lining is stainless steel;

[0224] The bottom elevation of the adjacent compartment of the initial thermal structure ≤ the initial lowest point elevation of the thermal structure ≤ the top elevation of the adjacent compartment of the initial thermal structure;

[0225] In a case where the initial liquid film continuity mark exists, the initial direction parameter of the thermal structure must be 1, i.e., the thermal structure is in a vertical direction.

[0226] In the example, by setting the above preset flow channel requirement, the accuracy of the target thermal structure parameters can be further improved.

[0227] In some examples, the preset thermal structure requirement includes:

[0228] The initial shape parameter = 0, indicating a flat plate; the initial shape parameter ≠ 0 indicates a cylinder, and the absolute value indicates the inner radius of the cylinder, the initial shape parameter > 0 indicates that the left compartment of the initial thermal structure is adjacent to the inner surface of the cylinder, and the initial shape parameter < 0 indicates that the left compartment of the initial thermal structure is adjacent to the outer surface of the cylinder;

[0229] The initial direction parameter is p1, indicating the vertical direction; the initial direction parameter is p2, indicating the horizontal direction and the left compartment of the initial thermal structure being above; the initial direction parameter is -p2, indicating the horizontal direction and the left compartment of the initial thermal structure being below, wherein p1≠p2;

[0230] For example, the values of p1 and p2 can be set according to actual conditions, which are not limited herein, for example, the value of p1 can be 1, the value of p2 can be 2, and the value of -p2 can be -2.

[0231] For example, the initial lining thickness > 0 indicates that the initial lining position is between the concrete and the left compartment, and < 0 indicates that the initial lining position is between the concrete and the left compartment, so that the lining position does not need to be defined separately.

[0232] For example, the initial liquid film continuity marker consists of 2 characters, such as “AB”, wherein the first character indicates the liquid film series, and the second character indicates the liquid film continuity surface. B=q1 indicates that the liquid film continuity exists on the left side, and B=q2 can indicate that the liquid film continuity exists on the right side. The values of q1 and q2 can be set according to actual conditions, which are not limited herein, but are not equal to each other. For example, the value of q1 is 1, and the value of q2 is 2.

[0233] In some examples, the preset thermal structure requirements further include that when the initial net surface area (when the initial shape is a cylinder), the initial concrete thickness, the initial lining thickness, the initial L-face paint thickness, the initial R-face paint thickness, the initial air gap thickness, and the initial liquid film continuity marker are not provided in the basic data, the default values are used instead, that is, the default settings are used for the above parameters, that is:

[0234] When the initial shape of the initial thermal structure is a cylinder, the initial net surface area = the unit net surface area of the initial thermal structure;

[0235] The initial concrete thickness, the initial lining thickness, the initial L-face paint thickness, the initial R-face paint thickness, and the initial air gap thickness are all 0;

[0236] The initial liquid film continuity marker is empty.

[0237] For example, the initial net surface area can be omitted when the initial shape is a cylinder, and the default initial net surface area = the unit net surface area when the initial shape is a cylinder; the first initial paint thickness is 0 by default, the second initial paint thickness is 0 by default, the initial air gap thickness is 0 by default, and the initial liquid film continuity marker is empty by default (that is, none).

[0238] Exemplarily, the electronic device is further provided with thermal structure derived parameters, which can include a thermal structure top elevation, an outer diameter (if a cylinder), a unit net surface area, a same thermal structure number, an inner surface characteristic length, and an outer surface characteristic length. The thermal structure top elevation = thermal structure initial lowest point elevation + initial height (thermal structure in vertical direction) or thermal structure initial lowest point elevation + initial concrete thickness (thermal structure in horizontal direction); the thermal structure outer diameter = |initial shape parameter| + initial concrete thickness (initial shape parameter ≠ 0); the unit net surface area = 2π * |initial shape parameter| * initial height (initial shape parameter ≠ 0) or initial net surface area (initial shape parameter = 0); the same thermal structure number = initial net surface area / unit net surface area; the inner surface characteristic length = 2 * |initial shape parameter| (initial shape parameter ≠ 0) or initial net surface area 0.5 (initial shape parameter = 0); the outer surface characteristic length = 2 * thermal structure outer diameter (initial shape parameter ≠ 0) or initial net surface area 0.5 (initial shape parameter = 0).

[0239] It should be noted that the thermal structure derived parameters are needed for modeling, but are not checked when merging.

[0240] In the present example, by setting the above preset thermal structure requirements, the demand for necessary parameters of the basic data can be simplified, and the input quantity can be reduced.

[0241] Exemplarily, in the case where the third checking result is not passed, an initial thermal structure parameter error prompt can be output to prompt the user which initial thermal structure and which parameters do not meet the preset thermal structure conditions, so as to facilitate the user to locate the error position and modify the error. After the user modifies, the user needs to return to the step of obtaining the containment basic data again to obtain d sets of initial thermal structure parameters corresponding to the d initial thermal structures in the containment, and then check the d sets of initial thermal structure parameters corresponding to the d initial thermal structures in the containment.

[0242] In some examples, the d sets of initial thermal structure parameters are preprocessed to obtain d sets of preprocessed first intermediate thermal structure parameters, including:

[0243] If the initial direction parameter of the initial thermal structure A0 shows that the initial thermal structure is horizontal and the left control body is below the initial thermal structure, the parameters of the initial thermal structure A0 are preprocessed, so that the first direction parameter of the first intermediate thermal structure A1 becomes horizontal and the left control body is above the first intermediate thermal structure A1, the first left control body name of the first intermediate thermal structure A1 is updated to the initial right control body name of the initial thermal structure A0, the first right control body name of the first intermediate thermal structure A1 is updated to the initial left control body name of the initial thermal structure A0, the first lining position of the first intermediate thermal structure A1 is updated to the opposite side of the initial lining position of the initial thermal structure A0, the first L-side paint thickness of the first intermediate thermal structure A1 is updated to the initial R-side paint thickness of the initial thermal structure A0, and the first R-side paint thickness of the first intermediate thermal structure A1 is updated to the initial L-side paint thickness of the initial thermal structure A0; in the case of a cylindrical thermal structure shape, if the initial shape parameter shows that the inner surface is adjacent to the left control body, the first shape parameter of the first intermediate thermal structure A1 is changed to that the inner surface is adjacent to the right control body, and if the initial shape parameter shows that the inner surface is adjacent to the right control body, the first shape parameter of the first intermediate thermal structure A1 is changed to that the inner surface is adjacent to the left control body; the remaining parameters remain unchanged;

[0244] If the initial direction parameter of the initial thermal structure A0 shows that the initial thermal structure is vertical, and the first shape parameter shows that the initial thermal structure shape is cylindrical and the left control body is outside the cylinder, the parameters of the initial thermal structure A0 are preprocessed, so that the first shape parameter of the first intermediate thermal structure A1 shows that the initial thermal structure shape is cylindrical and the left control body is inside the cylinder, the first left control body name of the first intermediate thermal structure A1 is updated to the initial right control body name of the initial thermal structure A0, the first right control body name of the first intermediate thermal structure A1 is updated to the initial left control body name of the initial thermal structure A0, the first lining position of the first intermediate thermal structure A1 is updated to the opposite side of the initial lining position of the initial thermal structure A0, the first L-side paint thickness of the first intermediate thermal structure A1 is updated to the initial R-side paint thickness of the initial thermal structure A0, the first R-side paint thickness of the first intermediate thermal structure A1 is updated to the initial L-side paint thickness of the initial thermal structure A0, and if the liquid film continuity mark of the initial thermal structure A0 shows that there is a continuous liquid film, the first liquid film continuity mark of the first intermediate thermal structure A1 is updated to the opposite side of the initial liquid film continuity mark of the initial thermal structure A0; the remaining parameters remain unchanged;

[0245] If the initial orientation parameter of the initial thermal structure A0 shows that the initial thermal structure is vertically oriented, the initial shape parameter shows that the initial thermal structure is a flat plate, and the initial liner position shows that the liner is adjacent to the left control body, the parameters of the initial thermal structure A0 are pre-processed, so that the first liner position parameter of the first intermediate thermal structure A1 shows that the liner is adjacent to the right control body, the first left control body name of the first intermediate thermal structure A1 is updated to the initial right control body name of the initial thermal structure A0, the first right control body name of the first intermediate thermal structure A1 is updated to the initial left control body name of the initial thermal structure A0, the first liner position of the first intermediate thermal structure A1 is updated to the opposite side of the initial liner position of the initial thermal structure A0, the first L-side paint thickness of the first intermediate thermal structure A1 is updated to the initial R-side paint thickness of the initial thermal structure A0, the first R-side paint thickness of the first intermediate thermal structure A1 is updated to the initial L-side paint thickness of the initial thermal structure A0, and if the continuous liquid film marker of the initial thermal structure A0 shows that there is a continuous liquid film, the first continuous liquid film marker of the first intermediate thermal structure A1 is updated to the opposite side of the initial continuous liquid film marker of the initial thermal structure A0; the remaining parameters remain unchanged.

[0246] For example, in the case where the initial orientation parameter is -2:

[0247] The first orientation parameter = 2;

[0248] The first left adjacent containment control body name = the initial right adjacent containment control body name;

[0249] The first right adjacent containment control body name = the initial left adjacent containment control body name;

[0250] The first shape parameter = the opposite of the initial shape parameter;

[0251] The first liner thickness = the opposite of the initial liner thickness;

[0252] The first L-side paint thickness = the initial R-side paint thickness;

[0253] The first R-side paint thickness = the initial L-side paint thickness;

[0254] The remaining first intermediate thermal structure parameters are the same as the corresponding initial thermal structure parameters.

[0255] That is, all the initial thermal structure parameters in the horizontal direction are uniformly changed to a thermal structure with a first orientation parameter of 2 after pre-processing.

[0256] It should be noted that the initial thermal structure parameters with an initial orientation parameter of 1 or 2 do not need to be processed.

[0257] Or, in some other examples, when the initial direction parameter is 1 and the initial shape parameter is < 0, such as the initial shape parameter = -1.5:

[0258] The first shape parameter = the absolute value of the initial shape parameter;

[0259] The first left side adjacent containment control body name = the initial right side adjacent containment control body name;

[0260] The first right side adjacent containment control body name = the initial left side adjacent containment control body name;

[0261] The first liner thickness = the opposite number of the initial liner thickness;

[0262] The first L-side paint thickness = the initial R-side paint thickness;

[0263] The first R-side paint thickness = the initial L-side paint thickness;

[0264] If the initial liquid film continuity mark is “*1” and the initial liquid film continuity mark is not empty, the first liquid film continuity mark is “*2”; if the initial liquid film continuity mark is “*2”, the first liquid film continuity mark is “*1”. Where “*” represents the same character;

[0265] The rest of the first intermediate thermal structure parameters are the same as the corresponding initial thermal structure parameters.

[0266] That is, all the vertical direction cylindrical initial thermal structure parameters are uniformly changed to the first direction parameter 1 and the first shape parameter greater than or equal to 0 after pretreatment.

[0267] It should be noted that the initial direction parameter is 1 and the initial thermal structure parameter with the shape parameter greater than or equal to 0 does not need to be processed.

[0268] Or, in some other examples, when the initial direction parameter is 1 and the initial shape parameter = 0, and the initial liner thickness < 0:

[0269] The first liner thickness = the absolute number of the initial liner thickness;

[0270] The first left side adjacent containment control body name = the initial right side adjacent containment control body name;

[0271] The first right side adjacent containment control body name = the initial left side adjacent containment control body name;

[0272] The first L-side paint thickness = the initial R-side paint thickness;

[0273] The first R-side paint thickness = the initial L-side paint thickness;

[0274] In the case that the initial liquid film continuous mark is not empty, if the initial liquid film continuous mark is "*1", the first liquid film continuous mark is "*2"; if the initial liquid film continuous mark is "*2", the first liquid film continuous mark is "*1". Wherein "*" represents the same character;

[0275] The rest of the first intermediate thermal structure parameters are the same as the corresponding initial thermal structure parameters.

[0276] That is, all the vertical direction plate initial thermal structure parameters are uniformly changed to the first direction parameter 1 and the first shape parameter 0 after preprocessing, and the initial liner thickness is greater than or equal to 0.

[0277] It should be noted that the initial direction parameter is 1, the initial shape parameter is 0, and the liner thickness is greater than or equal to 0, which does not need to be processed.

[0278] Through the above preprocessing, a basis is provided for subsequent merging into the first target thermal structure.

[0279] In some examples, the preset merging condition includes any one of a first preset merging condition, a second preset merging condition, a third preset merging condition and a fourth preset merging condition.

[0305] the N-1 air gap thickness of the N-1 intermediate thermal structure A (N-1) = the N-1 air gap thickness of the N-1 intermediate thermal structure B (N-1) i of the N-1 air gap thickness;

[0306] the N-1 liquid film continuity mark of the N-1 intermediate thermal structure A (N-1) and the N-1 liquid film continuity mark of the N-1 intermediate thermal structure B (N-1) i are all null, or the N-1 liquid film continuity mark of the N-1 intermediate thermal structure A (N-1) is “*1” and the N-1 liquid film continuity mark of the N-1 intermediate thermal structure B (N-1) i is “*2”, or the N-1 liquid film continuity mark of the N-1 intermediate thermal structure A (N-1) is “*2” and the N-1 liquid film continuity mark of the N-1 intermediate thermal structure B (N-1) i is “*1”.

[0307] That is, the N-1 intermediate thermal structure A (N-1) and the N-1 intermediate thermal structure B (N-1) are both vertical flat plates i The N-1 left containment control body name, the N-1 right containment control body name, the N-1 liner thickness, the N-1 L-face paint thickness, the N-1 R-face paint thickness and the N-1 liquid film continuity flag of the N-1 intermediate thermal structure A (N-1) are exactly opposite to those of the N-1 intermediate thermal structure B (N-1), and the rest of the parameters are equal.

[0322] It should be noted that there may be errors between the values of "the N-1 net surface area of the N-1 intermediate thermal structure A (N-1) ÷ the N-1 height of the N-1 intermediate thermal structure A (N-1)" and "the N-1 net surface area of the N-1 intermediate thermal structure B (N-1) ÷ the N-1 height of the N-1 intermediate thermal structure B (N-1) i ; i This condition can also be modified as:

[0329] The N-1 lowest point elevation of the N-1 intermediate thermal structure A(N-1) + The N-1 height of the N-1 intermediate thermal structure A(N-1) = The N-1 lowest point elevation of the N-1 intermediate thermal structure B(N-1) i of the N-1 intermediate thermal structure B(N-1), or, The N-1 lowest point elevation of the N-1 intermediate thermal structure A(N-1) = The N-1 lowest point elevation of the N-1 intermediate thermal structure B(N-1) i + The N-1 height of the N-1 intermediate thermal structure B(N-1)i;

[0337] In other words, both are vertical flat plates with intermediate thermal structures A(N-1) and B(N-1). i The names of the N-1 left-side containment control body, the N-1 right-side containment control body, the N-1 lining thickness, the N-1 L-side paint thickness, the N-1 R-side paint thickness, and the N-1 liquid film continuity markings indicate that the left and right adjacent containment control bodies are exactly opposite. The N-1 lowest point elevation and the N-1 height show vertical continuity, the net surface area per unit height is the same, and the N-1 concrete thickness and the N-1 air gap thickness are all equal.

[0338] It should be noted that the values ​​in "the (N-1)th net surface area of ​​the (N-1)th intermediate thermal structure A (N-1) ÷ the (N-1)th height of the (N-1)th intermediate thermal structure A (N-1)" and "the (N-1)th intermediate thermal structure B (N-1)" are related to the concept of "intermediate thermal structure". i The net surface area of ​​the (N-1)th digit ÷ the (N-1)th intermediate thermal structure B(N-1) i There may be an error between the two values ​​of "N-1th height". This condition can be modified as follows:
