1 shows an example of a drum and a package used in a waste management method according to an embodiment of the present invention.

Reference numeral 1a shows an example of the inside of a waste storage facility that collects and stores waste (eg, decommissioned waste) generated by the dismantling of a nuclear power facility in a drum 100 unit. As shown, a plurality of drums 100 may be stored in a waste storage facility.

According to an embodiment of the present invention, the drum 100 may be composed of a plurality of packages. For example, the plurality of packages may include the first package 110, the second package 120, and the third package 130. In FIG. 1, the number of the plurality of packages is shown as three, but the spirit of the present invention is not limited thereto, and the number of packages may be more or less.

Each of the plurality of packages may consist of waste of the same nature. The characteristics of the waste may be determined in connection with configuration management information based on the construction and operation history of structures, parts, and equipment in a facility to be dismantled.

Configuration management information is information on processes that verify the fact that specified requirements have been met by documenting the functional or physical properties of a nuclear power plant's configuration elements and recording and reporting them in the process of managing changes to those properties.

The purpose of configuration management is described in IAEA TECDOC-1335 as follows:

-To identify and document the design requirements of SSCs (Structures, Systems and Components) of nuclear power plants.

-To ensure that changes to design requirements have been properly filed, diagnosed, approved, issued, implemented, verified and documented and reflected in plant documentation.

-Safe, reasonable and economical judgment is to ensure that accurate information matching the actual shape of the power plant and its operating characteristics is available.

-The construction, operation, test and manufacture of the actual form of the power plant is consistent with the design requirements expressed in the design document and is consistent throughout the entire operation cycle.

Based on the configuration management information, waste generated in the same facility may have the same physical properties, chemical properties (eg, aluminum, iron) and radiological properties, for example. Accordingly, the same package management code is assigned to one package and can be managed based on this. Accordingly, waste can be managed in a package unit.

The package management code can indicate information about the package. For example, package management codes include waste generation history, waste types, waste storage facilities, container types, radionuclide information, and radioactive waste classification criteria information (e.g., high level, medium level, low level, extremely low level, etc.), It may contain codes indicating information on the mass of waste, the volume of waste, the degree of pollution of waste, and the dose rate of waste, among which the standard for classification of radioactive waste is Nuclear Safety Commission Notification No. 2014-, 'Classification of radioactive waste and its own 'Disposal Standards'. Information about these packages may be entered by a user or formed based on a database. Here, the database may be a term that refers to a set of pre-stored information based on a user's input and the like, using a database of the past operation history of facilities and devices by linking configuration management information at the construction and operation stage.

The waste treatment history may include information on which of the various processes associated with the waste in the package was processed, which combination of various treatment processes, or a single treatment process was repeated. For example, when treated with a decontamination process based on the generation history and characteristic information of the waste, a code pre-specified to indicate the decontamination process may be added to the package management code. Here, the waste-related process may be, for example, at least one of a production process, a packaging process, a classification process, a decontamination process, a melting process, an incineration process, a compression process, a transport process, a repackaging process, and a storage process. However, the type of the process related to the waste is not limited to the above-described example, and may include various processes related to the treatment of the waste.

The type of waste may include information on substances constituting the waste. For example, if the waste of the package consists of lead, a code pre-specified to represent lead can be added to the package management code. Here, the materials constituting the package are, for example, waste filter, waste paper, carbon steel, stainless steel, aluminum, lead, carbon steel, concrete, cement, activated carbon, pollution equipment, soil, sand, vinyl, plastic, fiber. It may be at least one of wood, paper, decontamination paper, waste shoes, laundry waste, asbestos, electric wires, rubber, graphite, and sludge.

The waste storage facility may include information about the facility in which the waste is stored. For example, when waste is stored in a temporary storage, a code pre-specified to represent the temporary storage can be added to the package management code. It goes without saying that the facility in which the waste is stored may be a place where waste is stored in a facility in which the waste management method is performed, and in the package management code, the waste storage facility may be set to various terms indicating such a place.

The type of container may indicate information on the type of container in which the package is stored. For example, when waste is stored in a drum, a code pre-specified to represent the drum can be added to the package management code. Here, the type of container may be a drum or a container.

The radionuclide information may indicate information on radionuclides (Radionuclide) contained in the waste. Radionuclides are easy for those skilled in the art, and specific examples thereof will be omitted.

The radiation level information may indicate information on the level of the radiation level of the waste. For example, when the level of the radiation level of the waste is an extremely low level, a predetermined code indicating that the radiation level is an extremely low level may be added to the package management code. Here, the radiation level may be one of self-disposal, extremely low level, low level, medium level, and high level according to the classification criteria of radioactive waste.

Pollution degree of waste refers to the degree of contamination of the surface of the waste, and the pollution degree of radioactive substances that emit alpha rays and radioactive substances that do not emit alpha rays are classified and presented. The dose rate of waste refers to the radiation dose measured at the surface of the package and drum of the waste.

The package management code may be updated for each execution when the processing of the package is performed multiple times. For example, if a decontamination process has been previously performed for a corresponding package, and a management code indicating it is added, if a melting process is performed, a management code indicating a melting process may be further added to the management code indicating the decontamination process. have.

The drum may be assigned a drum management code. The drum management code may indicate information about the drum. For example, the drum management code may include a code indicating information on at least one of the material of the drum, the steps in the processing process packaged with the drum, the storage facility in which the drum is stored, the mass of the drum, and the date of occurrence of the drum. have. Information on such drums may be entered by a user or formed based on a database.

The drum may be a standardized container for the transport of waste generated during the dismantling of nuclear power plants. In the waste management method of the present invention, the wastes may be configured as a package unit that is a collection of wastes having the same characteristics as a smaller unit than a drum, and a management code may be provided for each package unit. Through this, it is possible to easily manage the dismantling work and waste by efficiently managing the dismantling waste by managing the package unit rather than the drum of a large unit, which may be difficult to manage.

The waste management method of the present invention can efficiently track and manage the history of various waste treatment processes by managing them in package units, and establish the upper and lower information management system of packages and storage containers in consideration of dismantling site workability and applicability. Characteristic information can be easily grasped and used as basic data for history management in waste disposal and self-disposal.

Although not shown, the waste management system according to an embodiment of the present invention is provided with a management code for managing operation and characteristic information based on configuration management information of a dismantling object, and various for reducing radioactive waste based on generated characteristic information. Construction process (e.g. repacking, decontamination, melting, compression, incineration, storage, etc.) components, establishing a package-based information management system for efficient information management of waste treatment processes, and storing multiple packages in containers (e.g. drums) ) To evaluate the waste reduction amount through various treatment processes of the waste, which is packaged in) to manage the history of the treatment process, and to the classification criteria of radioactive waste (e.g., high level, medium level, low level, extremely low level, and self-disposal) Waste management department that can automatically classify according to the level and manage the generation amount by level, and the history of waste disposal required for final disposal and self-disposition It may include a waste history management unit that can be tracked in an integrated manner.

Figure 2 shows an example of a functional configuration of a waste management system according to an embodiment of the present invention. Used below… Wealth ','… Terms such as "means" a unit that processes at least one function or operation, which may be implemented by hardware or software, or a combination of hardware and software. Hereinafter, the content overlapping with the content of FIG. 1 will be omitted.

Referring to FIG. 2, the waste management system 200 includes a package management code granting unit 210, a packaging unit 220, a drum management code granting unit 230, a processing unit 240, and a package management code updating unit 250 , Repacking unit 260 may be included.

The package management code grant unit 210 may assign a package management code for each package unit of waste generated during the dismantling process of a nuclear power plant. The package management code may be a code generated based on the characteristics of waste included in the package. The package management code can indicate various information about the package, and accordingly, the waste can be managed for each package unit by identifying the package management code.

The package management code grant unit 210 may identify wastes based on a pre-stored database and determine characteristics of the wastes. The database may contain information on various wastes that can be generated when the nuclear facility is dismantled. The package management code grant unit 210 may determine the characteristics of the corresponding waste on the basis of this.

Although not illustrated, the package management code grant unit 210 may include a display unit that visually provides information to the user in some cases. In this case, the package management code grant unit 210 may display an input window to obtain a user input for determining characteristics of the waste through the display unit. The user input may include, for example, a user's touch input, click, double click, etc. that designates the characteristics of the waste among various waste characteristics stored in the database. 8 for a more detailed description of the input window.

The packaging unit 220 may package (or package) a plurality of packages, each of which is assigned a package management code, with a drum. For example, when three packages per drum can be inserted in the packaging unit 220, the plurality of packages may be divided into three and packaged in a drum. Based on the packaging, the packaging unit 220 may map a plurality of packages packaged in the drum to each other and store the information. The number of packages included per drum is only an example, and the spirit of the present invention is not limited by the above.

For example, the packaging unit 220 may include a separate memory. In this case, as the packaging operation is performed, the packaging unit 220 may map and store information about a drum and a package included therein in the memory. have. In some cases, the memory for storing such information may be included in the drum management code granting unit 230, which will be described later, and in this case, information on the drum and packages included therein may be provided to the drum management code granting unit 230. Can be saved.

The drum management code granting unit 230 hierarchically includes a package management code of each of a plurality of packages for a packaged drum, and can give the drum a management code including information about the drum to the drum. Granting the drum management code can be done in a variety of ways. For example, the drum management code can be output in the form of a QR code and attached to a predetermined position on the drum. In this case, when the drum management code is recognized by the waste management system 200, information on the drum can be identified.

The processing unit 240 may determine a processing process for each of a plurality of packages included in the drum based on the package management code and the drum management code. Based on recognizing the drum management code, the processing unit 240 may obtain information on the package management code included in the drum.

The processing unit 240 may include information on the processing process, and based on this, the processing unit 240 may determine a suitable processing process for each characteristic of the package. Specifically, the processing unit 240 may identify the package management code, identify information about each package included in the drum, and identify characteristics of the package to determine a suitable processing process for each package.

Information on the treatment process may refer to data previously stored in the treatment unit 240 in relation to waste treatment. The processing unit 240 may determine a processing process suitable for characteristics of the package based on information on the processing process. For example, the treatment process may include a decontamination process, a melting process, an incineration process, a compression process, and a self-disposal process. However, it goes without saying that the treatment process is not limited to the above-described example.

When a processing process is determined for each package by the processing unit 240, a processing process for each package may be performed accordingly. The processing process of the package may be performed by a separate processing device that performs the processing process. In some cases, the processing unit 240 may be connected to the processing device by wire or wirelessly to provide information on the determined processing process to the processing device so that the processing process of the package is performed.

When the execution of the processing process is completed, the processing unit 240 may receive information indicating that the processing process is completed from the processing device or may receive an input from the user indicating that the processing process is completed. The processing unit 240 may determine whether to perform the processing process based on this.

After the processing process is performed, the package management code update unit 250 may update the package management code by adding code including information on which the processing process has been performed to the existing package management code. For example, when a melting process is performed on one package, the package management code update unit 250 may update the package management code by adding a code designated in advance to indicate the melting process to the package management code.

The repackaging unit 260 may repackage a plurality of packages in units of the drum 100 based on the updated package management code. In this case, a drum management code indicating hierarchical information about the drum 100 and hierarchically including the package management codes of each of a plurality of packages may be provided to the drum 100 generated by repackaging. More detailed description related to the repacking will be described later.

Figure 3 shows the flow of each step of the waste management method according to an embodiment of the present invention. Needless to say, each step of the method illustrated in FIG. 3 may be performed in a different order as illustrated in the drawings. Hereinafter, contents overlapping with those described in FIG. 1 or 2 will be omitted.

Referring to FIG. 3, a package management code based on characteristics of waste may be provided for each package unit of waste (S110). The characteristics of the waste may be recognized by the package management code grant unit 210 or determined based on user input. A package management code indicating the characteristics of the determined waste can be assigned to each package.

A plurality of packages, each of which is assigned a package management code, may be packaged in the drum 100 (S120). The capacity of the drum 100 may be predetermined, and accordingly, a certain number of packages may be packaged with the drum 100. For example, the capacity of the drum 100 may be designated as 200L, and when the capacity of the package is 50L, four packages may be packaged as the drum 100. The capacity of the package has been exemplified in the same case, but is not limited thereto and may be configured with different capacity.

A drum management code may be assigned to the packaged drum 100 (S130). The drum management code may indicate information about the drum 100 and may hierarchically include a package management code for each package included in the drum 100.

The processing process for each package may be determined (S140). The processing process for each of the plurality of packages included in the drum may be determined based on the package management code and the drum management code.

After the processing process is performed, the package management code may be updated using a code including information on which the processing process has been performed (S150). Specifically, when the processing process is performed, the package management code may be updated by adding a code indicating the performed processing process to the predetermined package management code.

Figure 4 specifically illustrates the steps of determining and repackaging the treatment process of the waste management method according to an embodiment of the present invention.

Referring to FIG. 4, it may be determined whether a treatment process is required for a package of waste (S210). Specifically, the package management code included in the drum 100 may be identified through the drum management code of the drum 100 including the package, and it may be determined whether a processing process is required for the package based on the package management code. When the drum 100 includes a plurality of packages, a step of determining whether a processing process is required for each of the plurality of packages may be performed.

If a processing process is required for the package, a processing process may be performed for the package (S220). In addition, if a processing process is not required for the package, the package may be repackaged (S230). That is, if a treatment process is not required for the package, the package can be repackaged as it is without performing the treatment process. When repackaged, the package can be repackaged with other packages that were previously packaged together. In this regard, it will be described in more detail with reference to FIGS. 5 and 6.

Figure 5 shows an example of a conceptual diagram of a waste management method according to an embodiment of the present invention. Specifically, FIG. 5 shows an example in which a plurality of wastes contained in one drum are repackaged into one drum again after the treatment process is performed.

First, referring to FIG. 5, the initial drum 100 may include a plurality of packages. The plurality of packages may include a first package 110, a second package 120, and a third package 130. In this case, the first package 110 may include waste of the first characteristic, and the second package 120 and the third package 130 may include waste of the second characteristic.

The waste of the first characteristic may not require an additional treatment process, and the waste of the second characteristic may require an additional treatment process. Accordingly, the processing process of the first package 110 may not be performed, and the processing process of the second package 120 and the third package 130 may be performed.

Each of the package management codes of the second package 120 and the third package 130 may be updated to further include information on the processing process performed by the processing process. The second package 120 including the updated package management code will be referred to as a second 'package 120', and will be referred to as a third package 130 'containing the updated package management code.

The first package 110, the second 'package 120', and the third 'package 130' may be repackaged based on a drum unit. Here, since the drum unit is a unit including three packages, the first package 110, the second 'package 120', and the third 'package 130' into one final drum 100 '. Can be repackaged. Here, the final drum 100 ′ may have a drum management code different from the initial drum 100. For example, information on the drum creation date included in the drum management code of the initial drum 100 may indicate different dates. On the other hand, Figure 6 shows another example of a conceptual diagram of a waste management method according to an embodiment of the present invention. Specifically, FIG. 6 illustrates an example in which a plurality of drums are repackaged into a plurality of drums after a treatment process for each of the plurality of wastes is performed.

Referring to FIG. 6, each of the first initial drum 600 and the second initial drum 610 may include a plurality of packages. The first initial drum 600 may include a 1-1 package 601, a 1-2 package 602, and a 1-3 package 603. The second initial drum 610 may include a 2-1 package 604, a 2-2 package 605, and a 2-3 package 606.

Among the plurality of packages included in the first initial drum 600, the first-first package 601 has a first characteristic, and the first-2 package 602 and the first-3 package 603 have a second characteristic. You can. Among the plurality of packages included in the second initial drum 610, the 2-1 package 604 has the second characteristic, and the 2-2 package 605 and the 2-3 package 606 have the third characteristic. You can.

The waste of the first characteristic may not require an additional treatment process, and the waste of the second characteristic and the waste of the third characteristic may require an additional treatment process. For example, the waste of the second characteristic may require a melting process, and the third characteristic may require a decontamination process. Accordingly, the processing process of the first-first package 601 may not be performed, and the first-second package 602, the first-three package 603, the second-first package 604, and the second The -2 package 605 and the 2-3 package 606 may be subjected to processing processes suitable for each.

In some cases, when the treatment process is performed, the characteristics of the waste may change, and accordingly, the characteristics of the waste, which were originally different, may be similar. Specifically, referring to FIG. 6, the 2-2 package 605 and the 2-3 package 606 were for wastes having different characteristics from the 1-1 package 601, but the 2nd-2 As the treatment process suitable for the 2 package 605 and the 2-3 package 606 is performed, it may be changed into waste having characteristics similar to the 1-1 package 601. For example, when the decontamination process is performed on the 2-2 package 605 and the 2-3 package 606 having the third characteristic, the 2-2 package 605 and the 2-3 package 606 ) May be changed to 2-2 'package 605' and 2-3 'package 606' having the first characteristic.

In this case, wastes having the same characteristics may be repackaged into one drum. Specifically, the 2-2 'package 605' and the 2-3 'package 606' having the first characteristic as a result of performing the treatment process and the 1-1 package 601 of the first characteristic are excluded. 1 may be repackaged with the final drum 620.

In this aspect, the 1-2 package 602, the 1-3 package 603, and the 2-1 package 604 each have a 1-2 'package 602 having the same characteristics as a result of the processing process It may be changed to '), the 1-3' package 603 ', and the 2-1' package 604 '. Accordingly, the 1-2 'package 602', the 1-3 'package 603', and the 2-1 'package 604' may be repackaged with the second final drum 630. .

Repacking in FIG. 6 illustrates an example in which packages having the same characteristics are repackaged for each drum unit, but is not limited thereto. In some cases, repackaging may be performed in an arbitrary set of packages in which processing is performed or processing is not required. It may be.

7 shows an example of a package management code of waste in connection with shape management information of a dismantling object according to an embodiment of the present invention.

Referring to FIG. 7, the package management code is a code indicating various information related to waste included in the package, and may be configured to be managed in connection with configuration management information based on design and operation information of a dismantling target. Specifically, the package management code includes a first management code 701 for a project name related to the generation of waste, a second management code 702 for a physical breakdown structure (PBS), and a product for representing a tissue classification system. It may be composed of three management codes 703, a fourth management code 704 indicating a function classification system, and a fifth management code 705 indicating a serial number.

The first management code 701 may indicate which project waste is generated based on. For example, the first management code 701 may indicate information on a project name related to waste included in the package. For example, the database of the waste management system 200 may include information on various projects related to nuclear facilities or waste, and the project name associated with the package to which the first management code 701 is assigned in the database is selected and thus The corresponding code can be designated as the first management code 701.

Accordingly, the waste management system 200 may identify information on the project name associated with the package by recognizing the first management code 701 later.
