The present invention relates to a combustible radioactive waste input module and a portable radioactive waste treatment apparatus including the same, and more particularly, to a combustible radioactive waste input module capable of minimizing the possibility of exposure of workers by automating the process of inputting combustible radioactive waste; It relates to an integrated container-type incineration facility in which a miniaturized radioactive waste incineration treatment device is mounted in a transportable container including the same.

In general, radioactive waste generated during the operation of a nuclear power plant or nuclear-related facility is usually stored in a storage facility such as a nuclear power plant or a management facility such as a radioactive waste repository. However, the cost required for the final disposal of the radioactive waste by constructing the radioactive waste repository is substantial, which is a burden in reality.

In particular, in the case of an unexpected accident such as the Fukushima nuclear accident, radioactive waste is so large that it is impossible to manage it through a radioactive waste repository. Accordingly, there is a method of burning and disposing of radioactive waste using an incinerator as an example of the prior art for reducing the amount of radioactive waste and treating it. By incinerating the radioactive waste as described above, the amount of radioactive waste can be reduced, and there is an advantage that a large amount of radioactive waste can be reduced and treated at once.

However, the above-mentioned radioactive waste incineration treatment also has restrictions on the installation space due to the enlarged facility, and generates civil complaints from local residents because it generates radioactively contaminated incineration ash and exhaust gas.

As shown in FIG. 3 , the first door 1112 may be connected to the first opening/closing motor 1114 by a chain 1116 to move up and down in a sliding manner to open and close the buffer zone 1110 . In other words, before the drum 100 enters the buffer zone 1110 , the first door 1112 is opened, but after the drum 100 is gripped by the gripping unit 1130 , the first opening/closing motor 1114 operates It operates to close the first door 1112 to seal the buffer zone 1110 . In order to smoothly open and close the first door 1112 in a sliding manner, a rail 1118 and a roller 1119 may be provided.

And, when the first door 1112 is closed, a negative pressure is always formed inside the buffer zone 1110, and when the lid 110 of the drum 100 is opened, the air containing the radioactive material is prevented from leaking to the outside. In order to do this, the buffer zone 1110 communicates with an exhaust pipe (not shown), and air in the buffer zone 1110 that has moved through the exhaust pipe (not shown) may be discharged to the outside through a filter unit 3200 to be described later.

An automatic conveying device such as a conveyor may be applied to the unit 120 .

6 and 7 are views showing a state in which the drum is gripped by the gripping unit in the combustible radioactive waste input module according to an embodiment of the present invention.

The holding unit 1130 may be located in the buffer zone 1110 as described above. In addition, the holding unit 1130 may include a receiving member 1132 , a rotating member 1134 , and a pressing member 1136 . The accommodating member 1132 is fixed to the elevating unit 1140 so that the outer circumferential surface of the drum 100 is seated, and one side is opened to have an arc shape in cross section. In addition, the rotating member 1134 is rotatably hinged to at least one end of the receiving member 1132 to open and close the opened portion of the receiving member 1132 . In other words, the accommodating member 1132 and the rotating member 1134 may form a ring shape together and wrap a part of the outer peripheral surface of the drum 100 from the outside of the drum 100 to fix the drum 100 .

A first sensor S1 for detecting a position when the drum 100 approaches the inner circumferential surface of the receiving member 1132 for fixing the drum 100 may be provided. In other words, the first sensor (S1) is to detect how close the drum 100 moving toward the accommodating member 1132 by the horizontal movement unit 120 to the accommodating member 1132, the drum 100 and the accommodation When the distance between the members 1132 is less than or equal to a preset value, the rotating member 1134 is closed so that both the inner peripheral surfaces of the receiving member 1132 and the rotating member 1134 are in contact with the outer peripheral surface of the drum 100 to grip the drum 100 can do. Here, the preset value is a very small value and may be, for example, a value within 10 mm. That is, the first sensor S1 may grip the drum 100 when the drum 100 and the accommodating member 1132 are very close to each other. And, if the horizontal moving unit 120 is a device that automatically transports the drum 100 such as a conveyor, when the value measured from the first sensor S1 is less than or equal to a preset value, the horizontal moving unit 120 is stopped. can

The pressing member 1136 rotates the rotating member 1134 in the direction of holding the drum 100 and keeps the rotating member 1134 holding the drum 100, and in this embodiment, the rotating member ( As 1134), a pneumatic cylinder 1136 may be applied. That is, as the piston 1138 protrudes from the cylinder 1136 , it can be rotated by pushing the rotating member 1134 in a direction for gripping the drum 100 .

In this embodiment, the rotating member 1134 may be provided at both ends of the receiving member 1132 , respectively. That is, a pair of rotation members 1134 may be provided to face each other. And, a second sensor (S2) for detecting a distance from the other end is provided at one end of the pair of rotating members 1134 so that the distance between the ends of the pair of rotating members 1134 is constant. may signal to the pressing member 1136 to remain very close to each other. In other words, the piston 1138 may continue to press the rotating member 1134 to maintain the state in which the drum 100 is gripped. In addition, when the distance between the ends of the pair of rotating members 1134 is less than or equal to a preset value, the second sensor S2 operates the elevating member to output a signal for raising the drum 100 .

The elevating unit 1140 is coupled to the holding unit 1130 to elevate and lower the holding unit 1130, and as a result, the drum 100 can be moved up and down. The elevating unit 1140 is coupled to a rod-shaped guiding member 1142 and a holding unit 1130 having a length in the vertical direction, and a guiding member 1142 to be movable in the vertical direction with respect to the guiding member 1142. ) may include a vertical movement member 1144 coupled to the vertical movement motor 1146 for providing power so that the vertical movement member 1144 is movable.

In addition, the opening/closing unit 1150 includes a third sensor S3 for measuring the distance to the upper surface of the drum 100 when the opening/closing unit 1150 is raised by the elevating unit 1140. can do. The third sensor S3 may be installed very close to the opening/closing unit 1150 . Accordingly, when the value measured from the third sensor S3, that is, the distance from the drum 100 is less than or equal to a preset value, power may be applied to or removed from the electromagnet 1152. More specifically, if the value measured by the third sensor S3 in the state where the signal is input from the second sensor S2 and the drum 100 rises is less than or equal to a preset value, power is applied to the electromagnet 1152 to The drum 100 can be opened by allowing the lid 110 of the drum 100 to stick to the electromagnet 1152 . In addition, as will be described later, when a signal is output from the fourth sensor S4 and a value less than a preset value is input from the third sensor S3 after the drum 100 is overturned, the power is removed from the electromagnet 1152 and the electromagnet The lid 110 may be removed from 1152 so that the lid 110 covers the drum 100 .

The elevating unit 1140 detects the position of the drum 100 and, when the drum 100 reaches a preset position, stops the operation of the elevating unit and drives the overturning unit 1160 to overturn the drum 100 signal can be output. The elevating unit 1140 may raise the drum 100 until the drum 100 approaches the opening/closing unit 1150 as described above. Then, in order to overturn the drum 100, the drum 100 is slightly lowered in a state in which the lid 110 of the drum 100 is opened by the opening/closing unit 1150, and the fourth sensor S4 is at this time the drum The position of (100) can be detected.
