1 shows an example of a drum and a package applied to a radioactive waste management system according to an embodiment of the present invention.

First, referring to FIG. 1, a drum 100 applied to a radioactive waste management system may include a plurality of packages. The drum may be a standardized container for the transport of waste generated during the dismantling process of a nuclear facility. In the present invention, the waste may be configured in a package unit, which is a collection of wastes having the same characteristics, which is a smaller unit than the drum, and a management code may be assigned for each package unit. Through this, it is possible to efficiently manage the disposal history of waste by facilitating the dismantling operation and management of waste by managing it in a package unit instead of a large drum, which may be difficult to manage.

A drum management code may be assigned to the drum. 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 a material of the drum, a stage in a processing process packaged with a drum, a storage facility in which the drum is stored, a mass of the drum, and the date of occurrence of the drum. have. Information on such a drum may be input by a user or may be formed based on a database.

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 a first characteristic, and the second package 120 and the third package 130 may include waste of a second characteristic. Each of the plurality of packages may be composed of wastes of the same characteristics. 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 the facility to be decommissioned.

Here, the configuration management information is information on the processes of verifying that the specified requirements have been satisfied by documenting the functional characteristics or physical characteristics of the configuration elements of a nuclear power plant and reporting them in the process of managing changes in the characteristics. Based on configuration management information, wastes from 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 units of packages.

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

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

The first package 110, the second' package 120', and the third' package 130' may be repackaged on a per drum basis. Here, since the drum unit is a unit including three packages, the first package 110, the second' package 120', and the third' package 130' are used as 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.

2 shows an example of a functional configuration of a radioactive waste management system according to an embodiment of the present invention.

Referring to FIG. 2, the radioactive 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), may include a repackaging unit 260.

The package management code assigning unit 210 may assign a package management code for each package unit of waste generated during the dismantling process of a nuclear facility. For example, the package management code includes the history of waste generation, waste type, waste storage facility, type of container, radionuclide information, radioactive waste classification criteria information (e.g., high, medium, low, ultra-low level). Etc.), the mass of the waste, the volume of the waste, the pollution degree of the waste, and the dose rate of the waste. Information on radioactive waste classification standards follows the'Regulations on Radioactive Waste Classification and Self-Disposal Standards' of the Nuclear Safety Commission.

Information on such a package may be input by a user or may be formed based on a database. Here, the database may be a term that refers to a set of previously stored information based on a user's input and the like using a database on the operation history of past facilities and devices by linking configuration management information in the construction and operation stages. The package management code may be a code generated based on characteristics of waste included in the package. The package management code can represent various information on a package, and accordingly, by identifying the package management code, waste can be managed for each package unit.

In addition, the package management code may be updated for each execution when the package processing is performed multiple times. For example, if a decontamination process has been previously performed on the package and a management code indicating this is added, if the melting process is performed, a management code indicating the melting process may be added to the management code representing the decontamination process. have.

The package management code assigning unit 210 may identify the waste based on the previously stored database and determine the characteristics of the corresponding waste. The database may contain information on a variety of wastes that can be generated during the decommissioning of nuclear facilities. The package management code assigning unit 210 may determine the characteristics of the waste based on this.

The package management code assigning unit 210 may include a display unit (not shown) that visually provides information to a user in some cases. In this case, the package management code assigning 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 characteristics of waste stored in the database. For a more detailed description of the input window, refer to FIG. 8.

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

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 information on a drum and a package included therein and store it 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 the package included in the drum management code granting unit 230 Can be saved.

The drum management code assigning unit 230 hierarchically includes a package management code for each of a plurality of packages with respect to the packaged drum, and may assign a drum management code including information on the drum to the drum. Assigning a drum management code can be done in a variety of ways. For example, the drum management code may 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 radioactive waste management system 200, information on the drum can be identified.

The processing unit 240 may determine a processing process for each of the plurality of packages using waste information of the radioactive waste input to the package management code. At this time, the processing unit 240 may preset a target level for the overall (average) radioactive contamination of the radioactive waste, as well as a local level for the local (partial) radioactive contamination of the radioactive waste. The waste information may include information on at least one of the material, shape, volume, mass, density, thickness, surface contamination thickness, nuclide concentration distribution for surface contamination by nuclide, and nuclide concentration for volume contamination by nuclide. I can.

For example, the processing unit 240 may determine whether the waste information of the radioactive waste previously input in the package management code satisfies a preset target level, and determines whether the radioactive waste that satisfies the target level satisfies a preset local level. can do. Radioactive waste that meets the local level can be disposed of in its original state, ie without further treatment.

If the average radioactivity concentration does not satisfy the preset target level, the processing unit 240 may calculate (select) a treatment process (for example, a decontamination process) to satisfy the target level. In addition, the processing unit 240 may determine whether the waste information of the radioactive waste processed through the calculated treatment process satisfies a preset target level, and may determine whether the radioactive waste satisfying the target level satisfies a preset local level. Radioactive waste that satisfies the local level can be disposed of.

The treatment process for satisfying the target level may include a repackaging process, a decontamination process, a melting process, an incineration process, a compression process, and a self-disposal process. In this embodiment, as a treatment process for satisfying the target level, a decontamination process is applied, but is not limited thereto, and an optimal process for effectively treating radioactive waste may be used. When the decontamination process is calculated as a treatment process, the processing unit 240 may receive specific information on the decontamination process.

For example, the treatment unit 240 includes volumetric decontamination (volume decontamination decontamination coefficient by nuclide...), physical surface decontamination (surface removal thickness...), surface leachate decontamination (surface decontamination coefficient by nuclide, decontamination depth per nuclide) ...), remaining amount of waste before and after decontamination (volume change ratio, mass change ratio...), secondary waste generation ratio (solids that do not need solidification, solids that need to be solidified, liquid/sludge that needs to be solidified...), secondary of nuclides Information on the rate of flow to waste can be entered. In this embodiment, as a treatment process for satisfying the target level, a decontamination process is applied, but is not limited thereto, and an optimal process for effectively treating radioactive waste may be used.

If the waste information of the radioactive waste processed through the calculated treatment process does not meet the preset target level, the processing unit 240 performs the aforementioned treatment process until the waste information of the radioactive waste satisfies the preset target level. Can repeat. For example, in a state in which the target level and local level for radioactive contamination are set in advance, the processing unit 240 may dispose of the radioactive waste or continue the treatment process depending on whether the radioactive waste satisfies the target level and the local level. have.

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

The information on the treatment process may refer to data previously stored in the treatment unit 240 in connection with waste treatment. The processing unit 240 may determine a processing process suitable for characteristics of the package based on the information on the processing process.

When a processing process is determined for each package by the processing unit 240, the processing process may be performed for each package accordingly. The package treatment process may be performed by a separate treatment device that performs the treatment 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, thereby causing the package processing process to be performed.

When the processing process is completed, the processing unit 240 may receive information indicating that the processing process has been completed from the processing device or receive a user's input indicating the completion of the processing process. The processing unit 240 may determine whether to perform the processing process based on this. This processing unit 240 may be referred to as a'processing device'. Such a treatment device may be included in the radioactive waste management system 200, but may be implemented as a device independent from other components of the radioactive waste management system 200.

After the processing process is performed, the package management code update unit 250 may update the package management code by adding a 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 predetermined code 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 that hierarchically includes a package management code for each of a plurality of packages and indicates information on the drum 100 may be given to the drum 100 generated by repacking.

Meanwhile, the package management code grant unit 210, the packaging unit 220, the drum management code grant unit 230, the processing unit 240, the package management code update unit 250, and the repackaging unit 260 are microprocessors. It may be implemented by a computing device, a memory, etc.

In addition, the radioactive waste management system 200 according to an embodiment of the present invention may include a display unit for displaying a user interface. In this case, the radioactive waste management system 200 may provide a user interface indicating an input window for receiving information related to a package from a user.

The user interface may include, as a package name, a package ID, a location where a waste included in the package is generated, an input window for inputting information on a material, volume, dose rate, nuclide, and the like of the waste included in the package.

A characteristic of the package is determined based on the user's input to the input window, and information about this may be stored in a database. The database may include a management code representing characteristics of a package, and a package management code represented by a combination of various management codes may be determined based on the characteristics of the package.

In some cases, the user interface may include an input window for receiving input of drum information. In this case, an input window for inputting information about a container ID, a drum creation date, a drum material, etc. as the drum name may be included in the user interface.

Based on receiving a user input related to the information of the drum, the package and the drum may be mapped and the drum information may be stored in the database. Accordingly, when information on the drum is inquired, information on the package can be checked together, and the package can be efficiently managed.

Although not shown, in some cases, the radioactive waste management system 200 may display information stored in the database through the display unit. That is, the radioactive waste management system 200 may display information on a package or drum stored in the database based on a user input to the above-described user interface. In this case, the package for the drum may be displayed hierarchically, and accordingly, a part of the package information may be inquired by inquiring the information on the drum.

The user interface displayed on the radioactive waste management system 200 described in this specification is only an example, and various types of user interfaces conforming to the spirit of the present invention may be provided by the radioactive waste management system 200. to be.

3 shows the flow of each step of a method for managing a history of a radioactive waste treatment process according to an embodiment of the present invention. It goes without saying that each step of the method illustrated in FIG. 3 may be performed in a different order as illustrated in the drawings depending on the case. 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 assigned for each package unit of waste (S110). The characteristics of the waste may be determined based on the user's input or the waste is recognized by the package management code assigning unit 210. A package management code indicating the characteristics of the determined waste may be assigned to each package.

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

A drum management code may be given to the packaged drum (S130). The drum management code may represent information on the drum, and may hierarchically include a package management code for each package included in the drum.

A processing process for each package may be determined (S140). A 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.

Hereinafter, a step (S140) in which a processing process for each package is determined will be described in detail.

4 illustrates the flow of each step of a method of determining a radioactive waste treatment process according to an embodiment of the present invention, and FIG. 5 is a flow of a step of determining a method of determining a radioactive waste treatment process according to an embodiment of the present invention. Specifically shown.

4 to 5, the step of determining the treatment process (S140) includes a step of providing waste information of radioactive waste (S141), a step of determining whether the waste information satisfies a target level (S142), It may include a step (S143) of determining whether the radioactive waste satisfies the local level, and a step (S144) of disposing of the radioactive waste. The step S140 of determining such a processing process may be performed by the processing unit 240.

First, in the step (S141) in which waste information of radioactive waste is provided, waste information of radioactive waste may be input, information on a preset treatment process suitable for the input waste information may be input, and the input waste information Through this, the average concentration of radioactivity in radioactive waste can be calculated. The waste information may include information on at least one of the material, shape, volume, mass, density, thickness, surface contamination thickness, nuclide concentration distribution for surface contamination by nuclide, and nuclide concentration for volume contamination by nuclide. I can. In addition, the predetermined treatment process may include a repackaging process, a decontamination process, a melting process, an incineration process, a compression process, and a self-disposal process.

In this embodiment, a decontamination process may be used as a preset treatment process. Information on the decontamination process may include information on volumetric decontamination, physical surface decontamination, surface leaching decontamination, residual amount of waste before and after decontamination, secondary waste generation rate, and flow rate of nuclides to secondary waste. As for the average radioactivity concentration, volume contamination, uniform surface contamination, linear surface contamination, and exponential surface contamination may be considered. Since the average radioactivity concentration is a typical radioactivity average concentration (Bq/g) for each nuclide is used, a detailed description thereof will be omitted. Typical radioactivity average concentration (Bq/g) for each nuclide is as shown in Equation 1 below.

[Equation 1]

In Equation 1, i is the type of nuclide waste and n is the quantity (count) of the nuclide waste.

In the step S142 of determining whether the waste information satisfies the target level, it may be determined whether the provided waste information satisfies a preset target level. The target level can be understood as the target activity level in the treatment of the entire radioactive waste. This target level can be calculated from waste information from radioactive waste. For example, the target level may be calculated in consideration of a set waste level and an additional target reduction ratio.

In the step of determining whether the radioactive waste satisfies the local level (S143), it may be determined whether the radioactive waste that satisfies the target level satisfies a preset local level. The local level can be understood as the level of activity targeted for radioactive contamination generated in a portion of the radioactive waste (local portion).

In the step (S144) in which the radioactive waste is disposed, the radioactive waste satisfying the target level and the local level may be disposed in an original state.

When the average radioactivity concentration does not satisfy the preset target level, the step of determining the treatment process (S140) includes calculating a treatment process for satisfying the target level (S145), and the radioactive waste treated through the treatment process. The step of supplying the waste information of (S146), the step of determining whether the waste information satisfies the target level (S147), the step of determining whether the radioactive waste satisfying the target level satisfies the local level (S148), and , It may further include a step (S149) of disposing the radioactive waste satisfying the target level and the local level.

In step S145 in which a processing process for satisfying the target level is calculated (determined), a suitable processing process may be determined to satisfy a preset target level. For example, when the decontamination process is calculated as a treatment process, specific information on the decontamination process may be input. Specific information on the decontamination process may include information on volumetric decontamination, physical surface decontamination, surface leaching decontamination, residual amount of waste before and after decontamination, secondary waste generation rate, and flow rate of nuclides to secondary waste.

In step S146 of supplying waste information of the radioactive waste treated through the treatment process, waste information of the radioactive waste treated through the decontamination process, which is a calculated treatment process, may be supplied. At this time, the waste information includes the material, shape, volume, mass, density, thickness, surface contamination thickness of the radioactive waste changed through the decontamination process, the distribution of the nuclide concentration for surface contamination by nuclide, and the nuclide concentration for the volume contamination by nuclide. Can include.

In step S147 of determining whether the waste information satisfies a target level, it may be determined whether the provided waste information satisfies a preset target level. In step S148 of determining whether the radioactive waste satisfying the target level satisfies the local level, it may be determined whether the radioactive waste satisfying the target level satisfies a preset local level. In step S149 of disposing of the radioactive waste satisfying the target level and the local level, the radioactive waste satisfying the target level and the local level may be disposed.

In the step (S147) of determining whether the above-described waste information satisfies the target level, if the waste information does not meet the preset target level, the treatment process is calculated until the waste information satisfies the preset target level ( S145), the step of supplying waste information (S146), the step of determining whether the target level is satisfied (S147), the step of determining whether the local level is satisfied (S148), and the step of disposing of the radioactive waste (S149) are repeated. Can be.

Meanwhile, 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.

On the other hand, the radioactive waste treatment process history management method according to an embodiment is implemented in the form of a computer-readable recording medium storing a computer program programmed to perform the procedure included in this method, or in a computer-readable recording medium. It can be implemented in the form of a stored computer program. Since the method for managing the history of the radioactive waste treatment process implemented by the computer-readable recording medium includes the method for managing the history of the process of treating the radioactive waste described above, the description will be made using the above-described information, and the duplicate description will be omitted. .

As described above, according to the embodiment of the present invention, it is possible to systematically manage wastes of nuclear facilities requiring continuous observation and management. Accordingly, it is possible to systematically manage the information on the generation and treatment history of radioactive waste generated in nuclear facilities, secure the ease of treatment and disposal, reduce the amount of radioactive waste, and secure safety by reducing worker exposure.

In addition, according to an embodiment of the present invention, not only the overall radioactivity concentration of the radioactive waste, but also the local radioactive contamination contained in the radioactive waste is determined by determining the necessity of the treatment process, and the local radioactive contamination contained in the radioactive waste is also treated. By judging the necessity of the process, efficient treatment of radioactive waste can be achieved.

Meanwhile, although specific embodiments have been described in the detailed description of the present disclosure, various modifications may be made without departing from the scope of the present disclosure. Therefore, the scope of the present disclosure is limited to the described embodiments and should not be defined, and should be determined by the scope of the claims and equivalents as well as the scope of the claims to be described later.
