により設けられている。 In radioactivity processing facilities such as nuclear reactors, each processing chamber is hermetically divided by a thick shielding wall. An example of this is shown in the side sectional view of FIG. As shown in the figure, each processing chamber A, B is divided by a shielding wall 1, and the ceiling wall of each processing chamber A, B is provided with openings 2A, 2B. Radioactive substances 10 in radioactivity processing equipment 4A, 4B installed in processing chambers A, B are taken in and out through these openings 2A, 2B. This opening 2A, 2
B is always plugged with plugs 3A and 3B that fit thereto to prevent leakage of radioactivity to the outside. Note that this plug serves as a shielding door. In addition, in order to prevent exposure to radiation from the radioactive materials 10 taken out from the processing chambers A and B, an amber zone (intermediate chamber) C is provided at the top of the processing chambers A and B with a shielding wall 5.

The plugs 3A and 3B of the processing chambers A and B are moved by a crane 7 having a hook 9 and moving on a rail 6.
are pulled up and removed from the openings 2A and 2B, respectively, and then the radioactive material 10 is pulled up from the radioactivity processing equipment 4A to the amber zone C by the crane 7, and moved as it is into the radioactivity processing equipment 4B in the processing chamber B, Alternatively, it can be pulled up to the floor in Amber Zone C and stored in a cask (radiation-resistant container).
The entire cask is transported to the opening 2B of the processing chamber B, and then moved to the radioactivity processing equipment 4B in the processing chamber B for treatment. When the movement is completed, the crane 7 moves the plugs 3A and 3B to the respective openings 2A and 2.
B is fitted and sealed.

極めて面倒な操作が必要であつた。 However, with the conventional shielding door structure as described above, when moving radioactive materials, the plug that seals the opening must be removed and fitted using a crane, making operation difficult. It was very troublesome. In addition, since both plugs are removed and transported, radioactivity leaks from the openings, and to prevent this, a transportable shutter must be used and the shutter must be transported together with the cask. This required an extremely troublesome operation.
そこで、本考案は上記従来技術の欠点に鑑み、
運搬作業の操作を容易に行なえると共に放射能等

ができる。 FIGS. 2a and 2b show a planar cross-section of the processing chamber and a cross-section taken in the direction of the arrow, respectively. As shown in both figures,
Each of the processing chambers A and B is divided by a shielding side wall 1, and the shielding side wall 1 is provided with an opening 11 that opens from the floor surface. This opening 11 is formed in a size that allows the processing equipment 13 to enter and exit, and is provided with a shielding door 12 that is large enough to close this opening. This shielding door 12 has an eyebolt 16 installed in its upper part, and by hooking the end of a wire 17 to this eyebolt 16 and driving it with a crane, it moves upward and opens the opening 11. ing. In addition, a groove 15 having a width that allows the lower end of the shielding door 12 to fit into the floor surface where the shielding door 12 is located is provided along the shielding side wall 1 with a length approximately twice the width of the shielding door 12. It is being Therefore, when the shielding door 12 is closed, the lower end of the shielding door 12 enters into the groove 15 and is reliably sealed, thereby preventing radiation leakage.

る。 Further, as shown in FIG. 2a, a movable bed 18 is fitted into the groove 15 so as to be movable in the longitudinal direction of the groove. A moving rail 19 having the same width as the rails 14A and 14B is laid on the moving floor 18 in the same direction. When the shielding door 12 is raised and the opening 11 is opened, this moving rail 19
The moving bed 18 moves within the groove 15 to the opening 11 and is installed between the rails 14A and 14B, thereby connecting the rails 14A and 14B.
In this case, the end face of the groove serves as a stopper for the moving bed.

段溝に限定されることはない。 As shown in FIGS. 3a and 3b, which are cross-sections taken in the direction of the - arrow in FIG. 22. The chain 20 is connected to both ends of the moving bed 18, supported by each sprocket 21, and arranged in an annular shape, and rotated in directions c and d shown in the figure by the operation of a drive motor 22. Furthermore, since the upper side of the chain 20 passes through the inside of the groove 15, in this embodiment, the cross-sectional shape of the groove 15 is as shown in FIG. The bottom of the groove 15 is formed into a two-step groove with a small groove, and the chain 20 is inserted into the small groove.
It is structured so that it can pass through. Therefore, the shielding door 1
When the chain 2 is closed, the lower end of the shield door 12 is locked by the stepped portion in the groove 15, so that the chain 20 is not damaged. Note that the shape of this groove is not limited to the two-step groove as in this embodiment.

共に遮蔽扉１２をｂ方向に降ろせばよい。 When opening the opening 11 in such a shielding door structure, as shown in FIG.
If the processing equipment 13 is moved in the c direction and connected to the rails 14A and 14B, the processing equipment 13 becomes movable.
On the other hand, when closing the opening 11, the moving rail 19 can be moved in the d direction and the shielding door 12 can be lowered in the b direction, as shown in FIG. 3b.
尚、本実施例においては、処理室間を区画する
