TECHNICAL FIELD

The present invention relates to a nuclear power plant data-based design basis management system and a method therefor and, more particularly, to a system and method that can provide efficiency for configuration management in a nuclear power plant because a design basis document necessary for configuration management in a nuclear power plant can be managed in a systematic and integrated manner.

BACKGROUND ART

Nuclear power plants (hereinafter, “nuclear plants”) demand a very high level of safety. To this end, there is a need to apply the concept of configuration management.

Configuration management in a nuclear plant involves a system that always maintains consistency in nuclear plant design basis, facility configuration information, and physical configuration, which requires meeting contractors' and regulators' requirements and verifying and checking all configuration information if necessary. A configuration management process is an integrated management system that evaluates proposed changes to the configuration of a nuclear plant, determines the impact of such changes and implements the best way to implement the changes, and fulfills the procedures of approval, implementation, and documentation of changes to the configuration of the nuclear plant. A configuration management computer system for meeting these requirements should identify a configuration management target, define a product's architecture, track the impact of changes, and clearly express the association between information.

This allows for maintaining/managing consistency among design requirements for systems, structures, and components in a nuclear plant, facility configuration information (for example, a variety of design documents, drawings, and data), and physical plant configurations.

For a nuclear plant's configuration management, a design basis document is quite important. The design basis document may refer to a document that identifies the attributes of systems, structures, components, and topical areas and systematically integrates related documents and design basis information.

A design basis document is used to verify that the corresponding design meets higher-tier requirements by documenting and integrating design requirements, performance requirements, and specific parameters, all of which define design basis, can rule out factors degrading the safety of the nuclear plant by ensuring that facility replacements and performance changes occurring in the operation of the nuclear plant are carried out in compliance with the design basis, allows for integrated management of dispersed design basis when making changes to the design basis to improve the nuclear plant's performance, even with the complex association between the design basis, and serves as information that can be widely used as reference for operation, maintenance, and repair.

Despite the importance of design basis documents, the traditional configuration management using design basis documents has not been very satisfactory due to the difficulties in putting together a huge amount of information.

Moreover, there is currently no association between design basis documents even if design basis documents are created and used, but the categories of design basis included in a design basis document and a huge amount of information on design basis included in each category are simply managed in printouts. This makes it very difficult to review design basis documents when designing a nuclear plant or making design changes or when operating, maintaining, and repairing it. Also, it is practically very difficult to efficiently find associated design basis, since design basis to be included in a design basis document are fragmentarily described and dispersed in massive amounts of documents.

DISCLOSURE

Technical Problem

Accordingly, a technical problem to be solved by the present invention is to computerize design basis to be included in a design basis document, to effectively define an associative relationship between design basis, and to provide an effective system and method for a nuclear plant's operating entity to intuitively and efficiently detect and recognize design basis associated with a particular facility, using the associative relationship, when making design changes or in the operation or maintenance and repair of the nuclear plant.

Technical Solution

An exemplary embodiment of the present invention provides a nuclear power plant data-based design basis management system, the system comprising: a database that stores information on a plurality of design basis for defining a design basis document for configuration management in a nuclear power plant, information on categories corresponding to the design basis, among a plurality of categories, and an associative relationship between the plurality of design basis; a control module that, when a particular design basis corresponding to a particular one of the plurality of categories is selected by a user terminal, extracts provided information of the selected particular design basis from the database, the provided information of the particular design basis comprising information on the particular design basis and information on associated design basis having an associative relationship with the particular design basis and falling into other categories; and an interface module for providing the information extracted by the control module to the user terminal via a predetermined user interface, wherein the plurality of categories comprise design requirements (REQ), at least one design basis specification (DBS) for satisfying the design requirements, at least one structure, system, and component specification (SSCS) for satisfying the design basis specifications, supporting operation information (SOI), design parameters (DP), and supporting design information (SDI) for satisfying the structure, system, and component specifications, and physical structure, system, and component specification data (PSSCD) complying with the supporting operation information (SOI), design parameters (DP), and supporting design information (SDI).

The associative relationship is classified as a higher-tier, lower-tier, or same-tier category relationship between the design basis, wherein, when the particular design basis is selected, the control module provides the user terminal with associated design basis corresponding to higher-tier, lower-tier, and same-tier categories of the particular design basis in a distinguishable way.

The design requirements (REQ) are defined as a top-tier category, the design basis specifications (DBS) are defined as a lower-tier category of the design requirements (REQ), the structure, system, and component specifications (SSCS) are defined as a lower-tier category of the design basis specifications, the supporting operation information (SOI), design parameters (DP), and supporting design information (SDI) are defined as lower-tier categories of the structure, system, and component specifications, the physical structure, system, and component specification data (PSSCD) is defined as a lower-tier category of the supporting operation information (SOI), design parameters (DP), and supporting design information (SDI), and the supporting operation information (SOI), design parameters (DP), and supporting design information (SDI) are defined as same-tier categories.

The database stores information on a reference document for each of the design basis, and, when the particular design basis is selected, the control module provides information on the reference document through the interface module if there is a reference document for the particular design basis.

The database stores tag information for a facility corresponding to the physical structure, system, and component specification data (PSSCD).

The database further comprises physical plant configuration information for a facility corresponding to the physical structure, system, and component specification data (PSSCD), and, when the physical structure, system, and component specification data is selected, the control module provides the physical plant configuration information.

The control module creates traceable associative relationship information hierarchically representing information on a plurality of design basis having an associative relationship, from particular physical structure, system, and component specification data to the design requirements category, which is a top-tier category corresponding to the particular physical structure, system, and component specification data, and provides the created traceable associative relationship information to the user terminal.

When a certain design basis included in the traceable associative relationship information is selected, the user provides provided information of the selected design basis to the user terminal.

Another exemplary embodiment of the present invention provides a nuclear power plant data-based design basis management method, the method comprising: storing, by a nuclear power plant data-based design basis management system, information on a plurality of categories for defining a design basis document for configuration management in a nuclear power plant, information on at least one design basis included in each of the categories, and an associative relationship between the plurality of design basis; when a particular design basis corresponding to a particular one of the plurality of categories is selected by a user terminal, extracting, by the nuclear power plant data-based design basis management system, provided information of the selected particular design basis from the database, the provided information of the particular design basis comprising information on the particular design basis and information on associated design basis having an associative relationship with the particular design basis and falling into other categories; and providing, by the nuclear power plant data-based design basis management system, the extracted information to the user terminal via a predetermined user interface.

In the step of providing, by the nuclear power plant data-based design basis management system, the extracted information to the user terminal via a predetermined user interface, the nuclear power plant data-based design basis management system provides the user terminal with associated design basis corresponding to higher-tier, lower-tier, and same-tier categories of the particular design basis in a distinguishable way.

In the step of, when a particular design basis corresponding to a particular one of the plurality of categories is selected by the user terminal, extracting, by the nuclear power plant data-based design basis management system, provided information of the particular design basis from the database, if the particular design basis is the physical structure, system, and component specification data (PSSCD), the nuclear power plant data-based design basis management system extracts physical plant configuration information for a facility corresponding to the physical structure, system, and component specification data and includes the same in the provided information of the particular design basis.

The nuclear power plant data-based design basis management method further comprises: creating, by the nuclear power plant data-based design basis management system, traceable associative relationship information hierarchically representing information on a plurality of design basis having an associative relationship, from particular physical structure, system, and component specification data to the design requirements category, which is a top-tier category corresponding to the particular physical structure, system, and component specification data; and providing the created traceable associative relationship information to the user terminal.

The nuclear power plant data-based design basis management method may be implemented by a computer program in combination with hardware.

Advantageous Effects

A technical spirit of the present invention offers the advantage of computerizing design basis to be included in a design basis document, effectively defining an associative relationship between design basis, and making effective use of the design basis document, using the associative relationship, in design, operation, or maintenance and repair.

Furthermore, the user may intuitively find an association between associated design basis and a hierarchical relationship between them since they can distinguish associated design basis corresponding to higher-tier, same-tier, and lower-tier categories from each other when selecting a particular design basis, and this may be advantageous when detecting related reference information.

Furthermore, the user can check design basis associated with a particular facility at a time, from bottom-to-tier categories representing the particular facility, thereby allowing for integrated detection and management when a user action is needed on the particular facility.
