Description

Technology Field

[0001] The present invention relates to a radioactive waste packaging device, a radioactive waste packaging system including the same, and a radioactive waste packaging method. More specifically, it relates to a radioactive waste packaging device capable of disposing of particulate radioactive waste without a separate particle sorting process during the treatment process of radioactive waste including particulate radioactive waste, a radioactive waste packaging system including the same, and a radioactive waste packaging method. Background Technology

[0003] To proceed with the safe permanent disposal of low- and intermediate-level radioactive waste, the acceptance criteria for cave disposal facilities presented by the Radioactive Waste Accepting Agency (KORAD) must be met.

[0004] In this case, waste containing particulate matter is determined to have a dispersion risk based on particle size and composition ratio, and is generally classified as waste that does not meet acceptance criteria.

[0005] Specifically, it is stipulated that radioactive waste contains particulate matter if particles with a diameter of 0.01 millimeters or less account for 1 percent or more of the weight of the waste, or if particles with a diameter of 0.2 millimeters or less account for 15 percent or more of the total.

[0006] Conventionally, three methods were used to dispose of waste containing particulate matter in accordance with acceptance standards.

[0007] The first method is to separate and remove particles smaller than 0.2 millimeters, which is a method of separating only larger particles through particle size separation.

[0008] At this time, the particle sorting method had the problem of incurring additional manpower, time, and costs beyond drum packaging because a separate particle size separation process was required. In addition, since the separated fine particles must be processed separately, there is also the problem of the waste management process becoming longer.

[0009] The second is to reduce the risk of dispersion by immobilizing waste using cement.

[0010] In this case, when cement is used for immobilization, there was a problem in that the addition of cement to the waste significantly increased the total amount of waste, and additional equipment, manpower, time, and costs were required for immobilization.

[0011] Finally, a method was used to package particulate matter using a non-dispersing packaging material inside the drum.

[0012] In this case, by utilizing non-dispersing packaging materials, waste containing particulate matter could be simply packaged inside a drum without additional costs or separate processing steps, thereby meeting acceptance criteria while simultaneously preventing the problem of increasing waste.

[0013] However, there are currently no non-dispersion packaging materials available that are authorized by receiving agencies to package waste containing particulate matter. Therefore, the development of usable non-dispersion packaging materials is urgent to ensure the efficient disposal of waste with dispersion risks and to reduce management costs. The problem to be solved

[0015] The present invention aims to solve the aforementioned problems, and the objective of the present invention is to provide a non-dispersing packaging material capable of safely packaging radioactive waste containing particulate matter to meet the acceptance criteria for cavern disposal facilities.

[0016] Another objective of the present invention is to provide a non-dispersing packaging material that can reduce waste management costs without undergoing additional particle size separation or waste immobilization processes.

[0017] Another objective of the present invention is to provide a radioactive waste packaging technology that can effectively prevent the risk of dispersion of particulate matter while minimizing the increase in waste volume.

[0018] The problems of the present invention are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art to which the present invention pertains from the description below. means of solving the problem

[0020] According to one aspect of the present invention, a radioactive waste packaging device for packaging particulate radioactive waste without particle sorting is provided, comprising: an inner layer in which the particulate radioactive waste is contained; and an outer layer formed of a fiber material having a predetermined tensile strength, in which the inner layer is contained.

[0021] At this time, the inner lining is formed by joining an inner lining body formed of a transparent vinyl material, and a bonding reinforcement part formed by heat-bonding the inner lining body may be formed at the lower part of the inner lining.

[0026] At this time, one end and the other end of the first body of the outer shell in the longitudinal direction can be stitched multiple times along the height direction of the outer shell.

[0027] At this time, one end and the other end of the longitudinal side of the first body of the outer shell can be sewn four times with a single needle.

[0031] At this time, the binding cord can be tied in a form that forms two closed curves and two open curves while the binding part is wound multiple times.

[0032] At this time, both ends of the binding cord include markers that mark a position at a predetermined distance from each end of the binding cord, and on the two open curves, the markers may be positioned at a distance within a preset range from the center of the binding cord in a bound state.

[0033] At this time, the device further includes a binding member formed of a flexible material, and the inner lining includes a second binding portion that gathers radially inward with respect to a virtual central axis parallel to the height direction of the inner lining while the particulate radioactive waste is contained in the inner lining, and the binding member can bind the second binding portion.

[0034] At this time, the second binding member may be bound by the binding member while in a state where it is gathered radially inward with respect to the central axis and rotated at least once.

[0035] At this time, two of the above-mentioned binding members are provided so that the second binding part can be bound in two places in the height direction.

[0036] At this time, the above binding member may be formed with a terminal end that is not pointed.

[0051] In the following description, descriptions of some components may be omitted to clarify the features of the present invention.

[0052] FIG. 1 is a cross-sectional view illustrating the relationship between the length and the accommodation of a radioactive waste packaging device according to one embodiment of the present invention and a radioactive waste packaging system including the same. FIG. 2 is a front view of a radioactive waste packaging device according to one embodiment of the present invention.

[0053] A radioactive waste packaging device according to one embodiment of the present invention, a radioactive waste packaging system including the same, and a radioactive waste packaging method are related to a radioactive waste packaging device, a radioactive waste packaging system including the same, and a radioactive waste packaging method that can dispose of particulate radioactive waste without a separate particle sorting process during the treatment process of radioactive waste including particulate radioactive waste.

[0054] As illustrated in FIG. 1, a radioactive waste packaging system according to one embodiment of the present invention may include a radioactive waste packaging device comprising an outer shell (10) and an inner shell (20), and a drum (30) on which the radioactive waste packaging device is mounted.

[0055] At this time, when the outer skin (10) and the inner skin (20) are spread out in the up and down direction, the length of the outer skin (10) and the inner skin (20) can be formed to be longer than the up and down length of the drum (30).

[0056] As shown in FIG. 1, the vertical length (H1) of the outer shell (10) and the vertical length (H2) of the inner shell (20) can be formed to be longer than the vertical length (H3) of the drum (30).

[0057] Accordingly, when the outer shell (10) and the inner shell (20) are mounted on the drum (30) and the outer shell (10) and the inner shell (20) cover the drum (30), the exposure of the drum (30) to the outside can be minimized, thereby preventing particulate radioactive waste from escaping the radioactive waste packaging device and remaining in the drum (30) as much as possible.

[0058] As shown in FIG. 2, the radioactive waste packaging device mounted on the drum (30) is subsequently separated from the drum (30), at which time the radioactive waste (60) can be contained together in the inner lining (20) without the particulate radioactive waste and non-particulate radioactive waste being separated.

[0059] At this time, the inner lining (20) is sealed within the outer lining (10) with the radioactive waste (60) contained therein, so that the particulate radioactive waste can primarily be prevented from being dispersed outside the radioactive waste packaging device.

[0060] Additionally, the outer shell (10) can seal the inner shell (20) containing the radioactive waste (60) from the outside, thereby secondarily preventing the particulate radioactive waste from dispersing outside the radioactive waste packaging device.

[0061] At this time, the vertical length (H1) of the outer shell (10) and the vertical length (H2) of the inner shell (20) are formed to be longer than the vertical length (H3) of the drum (30), so that when the radioactive waste packaging device is mounted on the drum (30), the outer shell (10) can be primarily covered over the outside of the drum (30), and the inner shell (20) can be secondarily covered over the outside of the drum (30).

[0062] At this time, the outer shell (10) and the inner shell (20) may be formed in an overall cylindrical shape, and the bottom diameter of the inner shell (20) may be formed larger than the bottom diameter of the outer shell (10) and the bottom diameter of the drum (30).

[0063] FIG. 3 is a front view illustrating the appearance of the first body of the outer shell according to an embodiment of the present invention before it is joined. FIG. 4 is a front view illustrating the appearance of the second body of the outer shell according to an embodiment of the present invention before it is joined. FIG. 5 is a front view of the outer shell according to an embodiment of the present invention. FIG. 6 is a drawing illustrating a binding strap according to an embodiment of the present invention. FIG. 7 is a drawing illustrating the appearance of the binding strap tied according to an embodiment of the present invention. FIG. 8 is a drawing illustrating the outer shell and the binding strap according to an embodiment of the present invention.

[0064] Referring to FIGS. 3 to 5, the outer shell (10) of a radioactive waste packaging device according to one embodiment of the present invention may be formed in a cylindrical shape in which a first body (11) and a second body (12) are combined so as to prevent dispersion of radioactive waste (60) and to perform the role of protecting.

[0065] At this time, the first body (11) and the second body (12) may be composed of fibers of polypropylene (PP) fabric to ensure strong tensile strength and durability, and may be formed in a woven form of warp and weft threads of polypropylene fabric.

[0066] At this time, the warp is formed from a material having a tensile strength of 326 MPa or more, and the weft can be formed from a material having a tensile strength of 175 MPa or more.

[0067] In addition, the fabric constituting the outer shell (10) may have a thickness of 900D or more, and is formed to maintain sufficient mechanical strength while preventing the external leakage of radioactive waste.

[0068] Meanwhile, the first body (11) can be formed in a structure in which the left end (14) and the right end (16) shown in FIG. 3 are joined together in a square shape to form the side of the cylindrical structure of the outer shell (10).

[0069] At this time, the left end (14) and the right end (16) can be joined through four or more stitches to form the seam (19) shown in FIG. 5.

[0070] Through this, the radioactive waste packaging device according to one embodiment of the present invention can secure strong structural integrity that is not easily deformed even under external impact or tensile load.

[0071] Meanwhile, the second body (12) is formed to cover the lower part of the first body (11) and can be designed as a circular structure as shown in FIG. 4.

[0072] At this time, the second body (12) can be joined to the first joint (13) located at the bottom of the first body (11), and the joining of the first body (11) and the second body (12) can be performed through multiple stitches.

[0073] At this time, the first joint (13) and the second joint (15) can be joined by multiple stitching to ensure durability.

[0074] For example, the first joint (13) and the second joint (15) can be sewn four times with a single needle.

[0075] At this time, the second joint (15) of the second body (12) may be located 20 mm radially inward from the edge of the second body (12) toward the center of the second body (12).

[0076] Meanwhile, as illustrated in FIG. 5, a binding strap (40) is attached to the first binding part (18) of the assembled outer shell (10).

[0077] The binding cord (40) can perform the function of binding the first binding part (18) of the outer shell (10), and can be divided into two branches, wrapped in opposite directions, and then bound in the form of a butterfly knot.

[0078] At this time, as the butterfly knot is formed, the binding cord (40) can form a loop (46) portion formed of two closed curves and an end portion (48) formed of two open curves.

[0079] At this time, the length of the binding cord (40) can preferably be formed to be 1,000 to 1,050 mm. Also, referring to FIG. 6, a predetermined marker (42) may be placed on the binding cord (40) to ensure uniform binding through the binding cord (40) and to check the binding state of the binding cord (40).

[0080] The marker (42) can be marked at a position a first distance (L1) away from both ends of the binding string (40).

[0081] At this time, referring to FIG. 7, the first distance (L1) corresponds to the length of the end portion (48) of the binding cord (40) when the binding cord (40) is knotted, and can correspond to the distance between the end of the binding cord (40) and the marker (42).

[0082] At this time, the user can check the knot status of the binding string (40) by whether the marker (42) is located within a preset distance from the knot center (44).

[0083] For example, if the length of the loop (46) portion of the binding cord (40) is excessively long so that the marker (42) is not visible, the knot of the binding cord (40) may become unstable when pulled by the loop (46), so the knot can be fixed by pulling the binding cord (40) toward the end portion (48).

[0084] Conversely, if the distance between the marker (42) and the knot center (44) is excessively long beyond a preset distance range, the knot may be untied when the binding cord (40) is pulled toward the end (48), so the knot can be fixed by pulling the loop (46) portion of the binding cord (40).

[0085] Accordingly, the knot state of the binding string (40) can be checked according to the position of the marker (42) of the binding string (40), making it possible to easily check the binding state of the outer shell (10) visually.

[0086] Meanwhile, the binding cord (40) can be tied with a knot after wrapping the first binding part (18) of the outer shell (10) multiple times with respect to a virtual central axis parallel to the height direction of the outer shell (10) while radioactive waste (60) is contained within the inner shell (20) located within the outer shell (10).

[0087] Accordingly, the knot formed by the binding cord (40) can perform the function of preventing the binding cord (40) from coming undone after wrapping the first binding part (18) multiple times, and also the function of tightening the first binding part (18) after the binding cord (40) wraps the first binding part (18).

[0088] At this time, the outer shell (10) can be made of a polypropylene fabric with excellent wear resistance to protect radioactive waste for a long period of time, and has excellent resistance to external environmental factors such as moisture or chemicals, so that the radioactive waste can be safely stored.

[0089] Additionally, the outer shell (10) is designed to be slightly taller than the inner shell (20), thereby allowing the packaging to remain stable even after the waste is sealed.

[0090] Accordingly, the outer shell (10) can perform the function of protecting the waste from external impact and preventing radioactive waste from leaking out by applying a multi-layer protection structure with a thick fiber layer and strong seams.

[0091] FIG. 9 is a drawing illustrating an inner lining according to an embodiment of the present invention. FIG. 10 is an enlarged drawing illustrating a bonding reinforcement portion of the inner lining according to an embodiment of the present invention. FIG. 11 is an enlarged drawing illustrating a bonded inner lining according to an embodiment of the present invention.

[0092] Referring to FIGS. 9 to 11, the inner lining (20) may include a second binding portion (21) located at the top, a second receiving portion (23) located at the bottom of the second binding portion (21) in which radioactive waste (60) is received, and a bonding reinforcement portion (22) located at the bottom of the second receiving portion (23).

[0093] The inner lining (20) can directly accommodate radioactive waste (60) and perform the function of isolating the radioactive waste (60) from the outside.

[0094] To this end, the inner lining (20) can be formed from a transparent vinyl material capable of satisfying IPX7 level waterproof performance.

[0095] For example, the inner lining (20) can be formed from polyethylene (PE) material.

[0096] At this time, in order to simultaneously ensure airtightness and rigidity of the inner lining (20), the inner lining (20) can be formed in such a way that the lower part of the inner lining body, which is formed from a transparent vinyl material during the manufacturing process, is heat-bonded.

[0097] Accordingly, a bonding reinforcement part (22) can be formed on the lower part of the inner skin (20).

[0098] More specifically, the bonding reinforcement (22) can be formed to have a width of 1 mm or more. The bonding reinforcement (22) of the inner lining (20) not only has the function of simply sealing the inner lining (20), but can also reinforce the structure of the inner lining (20) by withstanding the load of radioactive waste (60) contained in the inner lining (20) at the bottom of the inner lining (20).

[0099] In the illustrated embodiment, the bonding reinforcement (22) is shown as being formed on the lower part of the inner skin (20), but it is not necessarily limited thereto, and the bonding reinforcement (22) may also be located on other parts of the inner skin (20), such as the side of the inner skin (20), to ensure the rigidity and stability of the inner skin (20).

[0100] Meanwhile, after radioactive waste (60) is contained within the inner lining (20), the second binding portion (21) of the inner lining (20) may be gathered radially inward with respect to a virtual central axis parallel to the height direction of the inner lining (20).

[0101] Afterwards, the second binding part (21) can be rotated at least once around the virtual central axis.

[0102] For example, the second binding part (21) can be rotated twice.

[0103] Afterwards, the second binding part (21) can be connected in a rotated state by a binding member (50) formed of a flexible material.

[0104] At this time, the binding member (50) can be formed as a cable tie, for example.

[0105] At this time, the binding member (50) may be formed in a round shape without the end portion being cut or processed to have a pointed tip.

[0106] Accordingly, it is possible to prevent the outer shell (10) from being damaged while the binding member (50) is received within the outer shell (10) together with the inner shell (20).

[0107] At this time, the binding member (50) is provided in multiple numbers, so that the second binding part (21) can be bound multiple times along the upper and lower directions of the second binding part (21).

[0108] For example, as shown in FIG. 11, two binding members (50) can bind the second binding member (21) in two places in the up and down direction.

[0109] FIG. 12 is a flowchart illustrating a radioactive waste packaging device according to one embodiment of the present invention and a radioactive waste packaging method including the same.

[0110] Referring to FIG. 12, a radioactive waste packaging device according to one embodiment of the present invention and a radioactive waste packaging method including the same may include the step of mounting the radioactive waste packaging device on a drum (30) (S100), the step of receiving particulate radioactive waste within the radioactive waste packaging device (S200), the step of binding an inner lining (20) (S300), and the step of binding an outer lining (10) (S400).

[0111] The radioactive waste packaging method of the present invention is carried out using an inner lining (20) and an outer lining (10) of a radioactive waste packaging device so as to safely seal and store radioactive waste.

[0112] First, a drum (30) in which a radioactive waste packaging device is placed is prepared. At this time, after placing an outer shell (10) inside the drum (30), an inner shell (20) is inserted inside the outer shell (10), and a step (S100) of mounting the radioactive waste packaging device on the drum (30) can be performed.

[0113] At this time, the vertical length (H1) of the outer shell (10) and the vertical length (H2) of the inner shell (20) are formed to be longer than the vertical length (H3) of the drum (30), so that when the radioactive waste packaging device is mounted on the drum (30), the outer shell (10) can be primarily covered over the outside of the drum (30), and the inner shell (20) can be secondarily covered over the outside of the drum (30).

[0114] Afterwards, with the upper part of the inner lining (20) open, radioactive waste (60) is introduced into the inner lining (20), and a step (S200) in which particulate radioactive waste is contained within the radioactive waste packaging device can be performed.

[0115] In this process, work can be performed to ensure that radioactive waste is completely contained within the inner lining (20).

[0116] Afterwards, when radioactive waste is contained within the inner lining (20), a binding step (S300) of the inner lining (20) can be performed by folding the second binding part (21) located on the upper part of the inner lining (20) and binding it using a binding member (50) made of a flexible material.

[0117] At this time, the binding member (50) that binds the inner skin (20) is formed in a shape where the end is not sharp, and serves to tightly bind and seal the second binding part (21) of the inner skin (20).

[0118] In this process, the inner lining (20) can be contracted radially inward along the central axis, and thus can be sealed to prevent radioactive waste from leaking out.

[0119] Afterwards, the sealing strength can be increased by rotating the second binding part (21) of the inner skin (20) one or more times while wrapped with the binding member (50), and if necessary, two binding members (50) can be used at positions spaced apart in the height direction to bind.

[0120] When the sealing of the inner skin (20) is completed, an outer skin (30) binding step (S400) can be performed in which the second binding part (21) of the outer skin (10) is wrapped and bound with a binding strap (40).

[0121] At this time, the binding cord (40) serves to close and seal the second binding part (21) of the outer shell (10), and can be bound in the form of a butterfly knot after being wrapped multiple times with both ends of the binding cord (40) wrapped in opposite directions.

[0122] At this time, markers (42) are included at both ends of the binding cord (40), and the markers (42) serve as a standard for checking whether the binding cord (40) is wound to an appropriate length. After the butterfly knot is completed, a verification process can be performed to check whether a uniform binding has been achieved by checking whether the markers (42) are located within a preset range from the center of the binding cord (40).

[0123] The bound outer shell (10) serves to protect the waste from external shocks or other environmental factors and can prevent radioactive waste inside the inner shell (20) from leaking out.

[0124] The radioactive waste packaging device, once packaged, remains sealed inside the drum (30), ensuring stability even during long-term storage or transport of the waste.

[0125] In addition, during the packaging process, the packaging condition may be photographed and recorded at the 25%, 50%, 75%, and 100% stages, and a process of visually inspecting for the presence of waste may be performed.

[0126] Through such a series of processes, a radioactive waste packaging method including a radioactive waste packaging device according to one embodiment of the present invention can effectively block radioactive waste and perform the function of minimizing environmental impact.

[0127] Although embodiments of the present invention have been described above, the spirit of the present invention is not limited to the embodiments presented in this specification. Those skilled in the art who understand the spirit of the present invention may easily propose other embodiments within the scope of the same spirit by adding, changing, deleting, or adding components, and such embodiments shall also be considered to fall within the scope of the spirit of the present invention.
