[0038] Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. In order to facilitate the entire understanding of the present invention, the same reference numerals are used for the same elements in the drawings and redundant explanations for the same elements are omitted.

[0039] A quality class of components constituting nuclear power plant equipment is classified into classes Q, A, and S so as to set a quality assurance level applied to a structure, a system, and device.

[0040] In relation to a quality class Q (safety related item), a safety related structure, system, and device are classified into a quality class Q according to a relevant regulation, and the Ordinance of the Ministry of Education, Science and Technology (Regulations on Technical Standards for nuclear reactor equipment) and the quality assurance requirements of 10CFR50 annex B are applied to a design, purchase, construction, and operation.

[0041] In relation to a quality class A (safety impact items), items or tasks corresponding to the following items other than safety related structures, systems, and devices are classified and managed as a quality class A, and appropriate quality assurance requirements designated for design, purchase, construction, and operation are applied thereto.

[0042] A. Items requiring quality assurance in regulatory requirements

[0043] B. Hanger or support related to maintenance of structural integrity of earthquake-proof category II class structures and corresponding device

[0044] C. Items selected by an operator in consideration of operation experience of nuclear power plants and cases of overseas nuclear power plants and a power generation stop causing device among power conversion and power generation equipment and major equipment related to emergency operation procedures.

[0045] In relation to a quality class S (general industrial item), a quality class S is applied to a non-safety related structure, system, and device other than a quality class Q and a quality class A and does not apply quality assurance requirements. The quality class S item is designed, produced, purchased, maintained, and operated according to accepted general industry specifications and standards.

[0046] A three-dimensional model system was used even in a conventional general construction industry field, and the three-dimensional model system was used for marketing to a general consumer and for grasping a construction progress. In a nuclear power plant construction field, a three-dimensional model system has been recently introduced, and technology of a conventional general construction industry field has been much applied. However, construction of a nuclear power plant differs in several aspects from that of a general construction industry field, and in particular, as described above, a quality class is given to each equipment of a nuclear power plant and is strictly controlled. Among quality classes, equipment corresponding to particularly a safety class is very important for shortening a construction time and managing a construction quality in nuclear power plant construction, but handling of a quality class is not reflected in a general three-dimensional model system.

[0047] According to an embodiment of the present invention, when constructing a nuclear power plant (hereinafter, referred to as a nuclear power plant), attribute data (weight, size, and material) of a shape of a three-dimensional model may be searched for according to a quality class (Q, A, S) of nuclear power equipment, a color of a shape of a three-dimensional model according to a quality class may be changed, and an alarm message may be automatically notified to a person in charge or a responsible person before and after a process and thus a major process can be grasped and safety of nuclear power plant construction can be improved.

[0048] Further, according to an embodiment of the present invention, while constructing a nuclear power plant, a progress status of each process may be grasped in real time and there is a function of enabling a user to view the corresponding component on a quality class basis and thus a specific device in a specific area of a power plant may be searched for only by a quality class using an ON/OFF function or a component may be grasped on a quality class basis in a specific area. Thereby, when constructing a power plant, a component that should be particularly careful can be grasped and in order to determine whether the component is installed, a material input and output status can be grasped in connection with an installation inspection result DB and a material input and output DB in real time.

[0049] In conventional three-dimensional model shape management, only a shape (equipment) itself is shown or only attributes (weight, size, and material) of a shape are represented, but according to an embodiment of the present invention, by providing quality class-based three-dimensional model power plant shape information, a quality of the shape can be grasped and safety can be enhanced. Further, by notifying a terminal of a responsible person or a person in charge through alarm, a construction status can be grasped in real time through a mobile device.

[0050] Particularly, in the case of a most important safety quality class Q, a component is displayed with a distinguishable color such as a red color and when a process of the component is performed, by automatically sending alarm to a terminal of a designated person in charge or a responsible person (designated manager), important processes can be grasped.

[0051] Further, when the process is completed, by providing alarm, it may be determined whether an important process is completed.

[0052] According to an embodiment of the present invention, by forming a power plant building and component into a three-dimensional model and by categorizing a power plant building and component according to a quality class, and when a corresponding quality class is selected, a three-dimensional model is changed to highlight (specific color) and thus an important component can be visually distinguished.

[0053] Further, a process status of the component is grasped in connection with a construction process schedule, and in the case of an important quality class, a function notifying a responsible person and a person in charge through alarm is implemented.

[0054] When linking with a process schedule, by linking a component installation inspection DB (installation checkable DB/installation inspection report) and material information about the process ACTIVITY (device), a material input/output and installation status can be grasped and all device components can be searched for and inquired based on a quality class.

[0055] FIG. 1 illustrates a screen for selecting levels and zones for each nuclear power plant building. As illustrated in FIG. 1, according to an embodiment of the present invention, in construction of a nuclear power plant, by displaying a plan view 11 of buildings constituting the nuclear power plant, a user may select a specific building, and by displaying a side view 13 representing a level of buildings, the user may select a level (height, pit) of the building to enable the user to select a desired building and level.

[0056] FIG. 2 illustrates a screen for selecting on/off according to a quality class of a component. When a user selects a desired region of a nuclear power plant, such as a predetermined building or level, a three-dimensional modeling result of the region may be displayed in a display area 10. Here, a quality class selection area 20 may be located, for example, at the right side of the display area 10. FIG. 3 illustrates a quality class list of components. As described above, each of components constituting equipment of the nuclear power plant may be classified into classes Q, A, and S and thus the quality class selection area 20 may include a class Q selection button 21, a class A selection button 22, and a class S selection button 23. A list display button 25 may be included in the quality selection area 20, and when the list display button 25 is clicked, a quality class list 27 may be displayed on the screen.

[0057] FIG. 4 illustrates a screen for displaying only a specific quality class.

[0058] FIG. 5 illustrates construction process management for each quality class. As illustrated in FIG. 5, according to an embodiment of the present invention, when three-dimensional modeling results of each component constituting a nuclear power plant are displayed in the display area 10, the results may be set to have different colors on a quality class basis. As illustrated in FIG. 5, the class Q may be displayed in gray, the class A may be displayed in green, and the class S may be displayed in blue. Accordingly, the user may intuitively recognize a quality class of the component with only a color of the components displayed in the display area 10.

[0059] According to an embodiment of the present invention, the user may select at least one of a plurality of components, and the selected components may be highlighted in a color that is noticeable, for example, red.

[0060] As illustrated in FIG. 5, according to an embodiment of the present invention, a construction process progress status of components having each quality class and components selected by the user through a construction process progress status display area 30 may be displayed so that a user may grasp it in real time. That is, in the construction process progress status display area 30, a process progress status 31 of a class Q component, a process progress status 33 of a class A component, a process progress status 37 of a class S component, and a process progress status 37 of a component selected by the user may be displayed.

[0061] FIG. 6 is a conceptual diagram illustrating selective opening of a three-dimensional model. As illustrated in FIG. 6, the user may select a specific building among buildings constituting a nuclear power plant and select a specific level in the building. Furthermore, as described above, a selection tool of a specific quality class may be added to selectively open a three-dimensional modeling result of a component of the selected quality class.
