1, a system 10 for designing a nuclear power plant includes a design requirement management server 100, a design data management server 200, and a design verification server 300 .

Design requirements management server 100 manages the design requirements to meet the safety regulations associated with nuclear power plants in a hierarchical manner. The design data management server 200 manages and stores the design data of the nuclear power plant. The design verification server 300 stores verification rules for verifying whether the design data conforms to the design requirements and verifies the design data according to the verification rules. Design requirement management server 100 notifies safety regulations or other design requirements related to the changed design requirements when any of the design requirements are changed.

The design requirements management server 100 is a server for managing safety regulations related to nuclear power plants and the design requirements associated therewith, and includes safety regulations to be followed in order to build and operate a nuclear power plant, Design requirements can be systematically managed.

Safety regulations are all regulations that must be met for the construction and operation of nuclear power plants, including, for example, laws, regulatory requirements, notices, specifications and standards, and contracts. Safety regulations refer to external enforcement regulations such as laws, the Nuclear Safety Commission of the Government, and Korea Hydro & Nuclear Power Co., Ltd., which produces electricity using nuclear power. For example, safety regulations include laws such as the Nuclear Safety Act related to nuclear safety, the protection and radiation disaster prevention law for nuclear facilities, the radiation safety management law for the living environment, the nuclear energy promotion law, the enforcement decree stipulating the administrative matters necessary for the enforcement of such laws, And the interpretation or details of the Nuclear Safety Commission rules and notifications and technical standards that detail the various licensing procedures, enforcement procedures and technical standards and enforcement rules, technical standards and administrative procedures necessary to actually implement the Enforcement Decree Regulatory standards that specify acceptable methods and condition specifications to meet technical standards, and industry standards and contracts such as KEPIC, ASME, IEEE, and ASTM.

Design requirements are internally defined by designers of nuclear power plants to meet safety regulations and include design criteria of the nuclear power plant to meet the safety regulations, design of the nuclear power plant to meet the design criteria Design specifications that define the function and design criteria of the objects, and design values that include the normal range of design parameters and design limit values to achieve the design specifications.

The design requirement management server 100 can hierarchically manage safety regulations and design requirements. Safety regulations and design requirements can be stored hierarchically by having safety regulations on the top floor and relating design requirements to relevant safety regulations. As described above, the design requirements include design criteria, design specifications, and design values, and the design requirement management server 100 associates the design criteria with the relevant safety regulations, associates the design specifications with the relevant design criteria , Design values can be related to relevant design specifications.

The design requirement management server 100 notifies the designer of the safety requirements or other design requirements associated with the changed design requirements when any of the design requirements is changed so that the designer can determine whether the changed design requirements meet the relevant safety regulations, And whether they do not conflict with each other. For example, the design specification of any one of the design specifications is changed, and the design requirement management server 100 can notify the designer of design standards and design dimensions related to the changed design specification. The designer can easily review whether the changed design specification meets the relevant design criteria and whether the underlying existing design dimensions do not conflict with the changed design specification.

The design requirement management server 100 may determine that the value of any one of the design requirements has changed so that if the value of the changed design requirement is inconsistent or out of the normal range with the value of the other design requirement associated with the changed design requirement, . According to another example, the design requirement management server 100 may change the numerical value or normal range of other design requirements according to the importance of other design requirements.

Designers can create design data for nuclear power plants in accordance with safety regulations and design requirements. Design data refers to data or documents that are the basis for the construction of a nuclear power plant and may be referred to as a design outcome. The design data management server 200 manages and stores design data of a nuclear power plant by a designer. The design data management server 200 can store a change history in which when the design data is changed, when and which part is changed.

Design data written by the designer may not meet safety regulations and design requirements. Because of the myriad of safety regulations and design requirements, designers may have created design data without knowing all of them, and if safety regulations and design requirements change, they may not be aware of these changes. The design verification server 300 can verify the design data based on verification rules to verify whether the design data that the designer has violated conforms to the safety regulations and design requirements. To this end, the design verification server 300 may store verification rules. Validation rules can be written to make the computer understandable according to design requirements.

The design verification server 300 can confirm that the design data does not cause any anomalies if the design data meets the design requirements and if the design data does not meet the design requirements, Parts and related design requirements. Because design requirements may need to be changed, the design verification server 300 may notify design requirements of interest as well as its associated design requirements.

2 is a block diagram of a design requirements management server of a nuclear power plant design system according to an embodiment of the present invention.

2, the design requirement management server 100 includes a design information input unit 110, a design requirement definition unit 120, a design object information unit 130, a history management unit 140, and a design information storage 150 . The design information input unit 110 may include a design information form unit 112 and a design information storage unit 114. The design information store 150 is a database for storing design information, and stores safety regulations 152 and design requirements 154. [ Design requirements 154 may include design criteria 155, design specifications 156, and design values 157. The safety regulations 152 and design requirements 154 are collectively referred to as design information.

The design information store 150 hierarchically stores design requirements 154 including design criteria 155, design specifications 156 and design values 157 as well as safety regulations 152. [ Specifically, the design information store 150 includes security constraints 152, design requirements 154, hierarchical associations between safety constraints 152 and design requirements 154, and design requirements 154, Is stored. More specifically, the hierarchical association between the security regulations 152 and the design requirements 154 may be a hierarchical association between the security regulations 152 and the design criteria 155. The hierarchical association between the design requirements 154 is a hierarchical association between the design criteria 155 and the design specifications 156 and a hierarchical association between the design specifications 156 and the design values 157 .

The safety regulations 152 are all regulations that must be met for the construction and operation of a nuclear power plant as described above, including for example, laws, regulatory requirements, notices, specifications and standards, and contracts. The design requirements 154 are internally defined by the designers of the nuclear power plant to meet safety regulations and include design criteria 155 of the nuclear power plant to meet the safety regulations 152, Design specifications 156 that define the functions and design criteria of the design objects that make up the nuclear power plant to meet the design specifications 156 and the design range including the normal ranges and design limits of the parameters to achieve the design specifications 156 Numbers 157 are included.

For example, the safety regulation 152 states that "the facility must be equipped with facilities to remove residual heat from the reactor core, including decay heat due to fission products, so that the fuel design limits and reactor coolant pressure boundary design conditions are not exceeded. "The law," Emergency water supply capacity should be sufficient to achieve room temperature shutdown conditions in which the residual heat removal system can be operated ", and" Safety class 1 equipment and support structures - reactor coolant A safety rating of 1 shall be assigned to the pressure-proof part of the equipment and its supporting structures that constitute the reactor coolant pressure boundary which may result in the loss of the reactor coolant beyond the supplemental capacity ".

The design specification 156 may include examples such as "swing check valve and motor driven isolation valve should be installed at the end of each water supply pump ". The design specification 156 also states that the "OOOO pump is a horizontal multistage centrifugal pump." While each pump recirculates the flow rate required to protect the pump to the auxiliary feedwater storage tank, the pressure range of the steam generator (O.OO OO.OO kg / cm ² A (OO ~ O, OOO psia)) can supply O, OOO L / min (OOO gpm) ~ O, OOO L / min (OOO gpm) Examples can be included.

Design values (157) include the values listed in the above design specification (156) from O.OO to OO.OO kg / cm ² A (OO to O, OOO psia) and O, OOO L / min , OOO L / min (OOO gpm) may be included as an example.

Each of the safety regulations 152 is stored in association with at least one design criterion 155 provided to meet the corresponding safety regulation 152 and each of the design criteria 155 meets the corresponding design criterion 155 And each of the design specifications 156 is stored in association with at least one design number 157 provided to meet the design specification 156. The design specifications 156 are stored in association with at least one design specification 156,

The design information store 150 may store safety regulations 152, design criteria 155, design specifications 156 and design values 157 using identification codes and serial numbers. The identification code may include a first identification code for identifying the design information and a second identification code for identifying the facility. The facility may refer to a system, structure, or facility associated with safety regulations 152. For example, the first identification code may correspond to "REQ" corresponding to the safety regulation 152, "DBS" corresponding to the design standard 155, "SSCS" corresponding to the design specification 156, And may include a corresponding "DP ". The second identification code has many types of facilities, so it is not illustrated here.

In the design information store 150, an item identification number can be used to identify design information items and correlate design information with each other. For example, the item identification number may have a format such as "first identification code-second identification code-serial number ". For example, an item identification number such as "REQ-XX-001" may be assigned to the first safety regulation regarding the facility XX with the second identification code "XX ".

DBS-XX-001, contents: (content entry), related design information: REQ-XX-007, SSCS-XX-024 "and the like are stored in the design information storage 150 using this item identification number Can be stored together. This is because the first design standard (DBS-XX-001) for the facility (XX) is the same as the first safety standard (REQ-XX-007) 24 Design Specification (SSCS-XX-024).

The design requirement defining section 120 can hierarchically define the safety regulations 152 and the design requirements 154. [ Safety constraints 152 and design requirements 154 stored in the design information store 150, and their associations, can be defined by the design requirement defining section 120. [ Although not shown in FIG. 2, the design requirement defining section 120 may include a safety regulatory store that stores safety regulations 152 as a top level in the design information store 150 along with associated design criteria 155 have. Design requirements defining section 120 is a design that stores design criteria 155 as a lower layer of safety regulations 152 in design information store 150 along with associated safety regulations 152 and associated design specifications 156. [ And may include a reference storage unit. Design requirements defining section 120 is a design that stores design specifications 156 as a lower layer of design criteria 155 in design information store 150 along with associated design criteria 155 and associated design values 157. [ And a specification storage unit. The design requirement defining section 120 may include a design numerical value storing section that stores the design values 157 as a lower layer of the design specifications 156 in the design information store 150 together with the related design specification 156 . XXS-XX-024 "in the above example designates the design requirement defining section 120 (DBS-XX-001, content: (write content), related design information: REQ- And stored in the design information storage 150 by the reference definition unit.

The design information input unit 110 inputs design information including safety regulations 152, design criteria 155, design specifications 156 and design values 157 stored in the design information storage 150 And provides an interface to do so. The design information input unit 110 includes a design information form unit 112 and a design information storage unit 114. The design information form unit 112 can define characters, numbers, units, etc. of design information. Here, the units may be units such as flow rate, temperature, pressure, and the like. In the above example, units such as "kg / cm ² A" and "psia" can be defined as units of pressure, and units such as "L / min" and "gpm" For example, since the information stored as the design number 157 can be composed only of numbers, the design information form section 112 can define units of these numbers.

The design information storage unit 114 transmits the design information input through the design information input unit 110 to the design requirement defining unit 120 and the design requirement defining unit 120 associates the design information with other design information And the design information may be stored in the design information storage 150 together with the association with other design information. The design information stored in the design information storage 150 includes detailed values as it goes down to the lower layer, and these detailed values can be managed through the design information input unit 110. [

The design target object information unit 130 may store design objects constituting the nuclear power plant and identification codes for identifying the design object. Here, the design objects refer to components included in the design data, for example, a system, a structure, a facility, and the like that constitute a nuclear power plant. For example, the design target body may include a swing check valve, a motor-driven isolation valve, a water pump, a pipe, and the like. For example, "AF-PP01" can be defined as an identification code for the water supply pump by using the designing object information unit 130. [

The history management unit 140 can manage the history including the change history when the safety regulations 152 or design requirements 154 stored in the design information storage 150 are changed. For example, the history management unit 140 can manage the changed design information by using the revision number whenever the design information is changed. Accordingly, the contents and system of past design information can be confirmed.

3 is a block diagram of a design data management server of a nuclear power plant design system according to an embodiment of the present invention.

Referring to FIG. 3, the design data management server 200 may include a design data manager 210, a history manager 220, and a design data store 230.

The design data store 230 may store design data, that is, the design results, which are the basis for constructing the nuclear power plant. The design data may include design objects constituting a nuclear power plant, and their connection information. The design data may include specific specifications of the design objects, such as size, area, capacity, thickness, and the like. The design data can store information about how the design objects are connected. The design data can be stored using the identification code of the design object. For example, connection information between design objects may be defined using an identification code for identifying design objects.

The design data management unit 210 may store the design data in the design data store 230 or provide an interface through which the data can be modified.

The history management unit 220 can manage the history including the change history when the design data stored in the design data store 230 is changed. For example, each time the design data is changed, the history management unit 220 can manage the changed design data using the revision number, and the contents of the past design data can also be confirmed.

4 is a block diagram of a design data management server of a nuclear power plant design system according to an embodiment of the present invention.

Referring to FIG. 4, the design verification server 300 may include an association unit 310, a design verification unit 320, and a verification rule repository 330. The design verification unit 320 may include a design rule generation unit 322 and a verification processing unit 324. [

The design verification server 300 sends verification rules to the verification rule store 330 to verify whether the design data stored in the design data store 230 matches the design requirements 154 stored in the design information store 150. [ Lt; / RTI > The design verification server 330 also determines whether the design data stored in the design data store 230 conforms to the design requirements 154 stored in the design information store 150 in accordance with the verification rules stored in the verification rule store 330 Can be verified.

The linking unit 310 links design objects of the design data stored in the design data store 230 and design objects of the design requirements 154 stored in the design information store 150 for verification operation of the design verification server 300 Can be linked to each other. The linking unit 310 can link the design objects of the design data with the design objects of the design requirements 154 using the identification code. The identification code may be stored in association with the design target object corresponding to the design target object information unit 130. [

The design verification unit 320 can verify whether the design data conforms to the design requirements 154 based on the verification rules stored in the verification rule store 330. [ The design verification unit 320 may include a design rule generation unit 322 that generates verification rules corresponding to the design requirements 154 and a verification processing unit 324 that verifies design data based on the verification rules.

Design rule generator 322 may generate verification rules written in a language understood by the computer in response to design requirements 154. [ The safety regulations 152 and design requirements 154 stored in the design information store 150 are described in the form of a sentence that can be understood by the designer. Safety regulations (152) or design requirements (154) can not be directly understood by computers, so they must be transformed into verification rules that are written in a way that the computer understands. The verification rules can be generated by a person in a computer language.

The verification processing unit 324 can verify the design data stored in the design data storage 230 using the verification rule generated by the design rule generation unit 322. [ The verification processing unit 320 can determine whether the design data has been prepared in accordance with the design requirements 154 by searching the design data according to the verification rule.

For example, the design specification " The swing check valve and the motor drive isolation valve should be installed at the rear end of each water supply pump "shown as an example above can be converted into the verification rule by the design rule generation unit 322. [ The verification processing unit 324 can verify the design data with this verification rule.

The verification processing unit 324 can search the feed water pump and the steam generator from the design data and limit the search range between the feed water pump and the steam generator. For example, when it is assumed that the identification code of the water supply pump is "AF-PP01 ", it is possible to retrieve the design target object having the identification code" AF-PP01 " The design data may include various feature information as a subclass of the feed pump (AF-PP01).

The verification processing unit 324 can confirm the identification code of the pipe connected to the rear end of the searched feed water pump AF-PP01 according to the verification rule. Assuming that the identification code of this pipe is "AF-AA001 ", the verification processing unit 324 can search for the pipe having the identification code" AF-AA001 "in the design data according to the verification rule. The design data may include various feature information as a subclass of the pipeline (AF-AA001). For example, the feature information may include the flow direction of the water supply. If the flow direction of the water supply is a forward direction, the identification code of another design object to which the pipe (AF-AA001) is connected can be checked and the design object having this identification code can be searched.

In this manner, the design objects connected to the piping can be searched sequentially until the steam generator connected to the pipeline is searched. The verification processing unit 324 can check whether a design object having an identification code corresponding to the swing check valve or the motor drive isolation valve exists between the water supply pump AF-PP01 and the steam generator.

If there is a design target object having an identification code corresponding to the swing check valve or the motor drive isolation valve between the feed pump AF-PP01 and the steam generator, the verification processing unit 324 determines that the verification target has passed the verification rule, The design data can be verified again according to the following verification rule. If there is no design object having an identification code corresponding to the swing check valve or the motor drive isolation valve between the feed pump AF-PP01 and the steam generator, the verification processing unit 324 has failed to pass the verification rule And notify the designer that the verification rule has not been passed. The verification processing unit 324 can also notify the designer of the identification code including the position of the water pump AF-PP01 that failed to pass the verification rule and information on the verification rule.

A method for changing design data using the nuclear power plant design system 10 according to an embodiment of the present invention will be described.

The design data of a nuclear power plant may need to be changed. The design data management server 200 can transmit the changed design data to the design verification server 300 when the design data stored in the design data storage 230 is changed. The design verification server 300 can verify whether the changed design data conforms to the design requirements 154 in accordance with the verification rules stored in the verification rule repository 330. [ If the modified design data conforms to the design requirements 154 as a result of the verification according to the verification rule, the design verification server 300 can notify that the changed design data conforms to the design requirements 154. However, if the verification result is negative in the verification rule, the design verification server 300 can transmit the design requirements 154 that the modified design data does not match to the design requirement management server 100. [ The design requirement management server 100 can notify the designer of the design requirements that the changed design data does not match. In addition, the design requirement management server 100 can additionally inform the designer of safety regulations or other design requirements related to design requirements for which the changed design data does not meet.

According to another example, a request to change the design data may be received from the designer. The designer can use the nuclear plant design system 10 to identify design data and design requirements associated with the change request. The designer can determine if the design requirements need to be revised. This judgment can be provided by the nuclear plant design system 10. [ To do this, the designer may find design constraints 154 that are inconsistent in modifying the design data and verifying the revised design data, and thus found design requirements 154 need to be modified . ≪ / RTI >

If a new design requirement is to be added, the designer can use the design information input unit 110 and the design requirement definition unit 120 to store new design requirements in the design information store 150. [ At this time, other design requirements related to new design requirements or information on safety regulations may be stored together.

The designer can modify the design requirements 143 stored in the design information storage 150 using the design information input unit 110 and the design requirement definition unit 120. [ If the specific numerical value of the design requirement needs to be changed, it can be modified using the design information input unit 110. [ When the design requirement is added or changed in this manner, such a history can be stored in the history management unit 140.

On the other hand, the designer can change the design data using the design data management server 200. The modified design data may be stored in the design data store 230. Also, the history management unit 220 can leave a design data change history.

Thereafter, the changed design data is transmitted to the design verification server 300.
