易に行えるホットセル内の整備作業方法に関する。[Detailed Description of the Invention] The present invention enables maintenance work such as inspection or repair of equipment using a monitoring device, manipulator, etc. installed in a hot cell to be easily performed by remote control in places where such work is difficult. Concerning maintenance work methods in hot cells.
放射性物質の存在するホットセル内での種々の作業は、

て行っていた。Various operations in a hot cell where radioactive materials are present include:
As shown in FIG. 1, maintenance and inspection of the hot cell 2 yen equipment is carried out using a remotely controllable manipulator 1, and a television camera 3 attached to the manipulator 1 and a hot cell 2
A monitoring device 4 was used to monitor the work of the manipulator 1 using a television camera attached to a circle, and the inside of the hot cell 2 was directly viewed from outside through a blocking window 5.
ところがマニプレータ１を移動させる天井クレーン６や

レール８上やこれより更に上方にある天井クレーン６ａ
等に対する観察は困難でありホットセル２内の十分な点
検が行なえなかった。However, inspection work for the overhead crane 6 that moves the manipulator 1 and the overhead crane 63 that is installed above and that carries equipment etc. cannot be seen from the tracking window 5 because these are located near the ceiling of the hot cell 2. Also, monitoring device 4
Even in the middle of the day, you are looking up, and you can only observe the parts that are facing downwards. Furthermore, there is an overhead crane 6a on the guide rail 8 on which the manipulator 1 moves or further above this.
It was difficult to observe the hot cell 2, etc., and the interior of the hot cell 2 could not be sufficiently inspected.
これ全カバーする為に多くのテレビカメラを取り付ける
ことは、非常に不経済であり、実用的ではない。甘た上
述した場所においての点検作業のみならず部品の修理作

に行えない。Installing many television cameras to cover all of this would be extremely uneconomical and impractical. Not only inspection work at the above-mentioned locations, but also parts repair work and replacement work, etc., cannot be carried out satisfactorily because maintenance equipment is not provided.
上方で作業が行える唯一の箇所と言えばホットセル２上
部に設けた開閉自在の遅閉トラップ９の真下に位置する
所のみであり、非常に不便であった。The only place where work can be done above is the place directly below the openable and closable slow-closing trap 9 provided above the hot cell 2, which is very inconvenient.
そこで本ぞ明はこのような不具合を解消し、ホットセル

メラ１５で、案内レール８ａ上の点検をする。This example is a hot cell 2 yen overhead crane 6.6a
This is a method to perform not only inspection work but also maintenance work such as repair and replacement of various equipment. A lifting device 12 attached to a small overhead crane 11 installed in a cask (airtight container) 10 that is shielded from the radioactive atmosphere has two overhead cranes 6.6a installed inside the hot cell 2. A maintenance device 13 that can run along the guide rails 8 and 8a is suspended, and this maintenance device 13 is equipped with a manipulator 14 for repairing and replacing various devices, and a television camera 15 for inspection. There is. 1 This maintenance device 13 is connected to an external monitor television 17 and a controller 18 via a cable 16, and the movement of the maintenance device 13 and the operation of the manipulator 14 and inspection television camera 15 are performed by remote control. At the bottom of C1 and cask 10,
A door 19 that can be opened and closed is provided. hot cell 2
As part of the maintenance work procedure, first, a large overhead crane 20 installed outside the hot cell 2 transports all casks 10 onto the hot cell 2, and opens and closes the cask 10.
9 is positioned so that it faces the late closing trap 9 of the hot cell 2. The overhead crane on the side to be worked on, in this embodiment the upper overhead crane 6a, is positioned in advance directly below the late-closing trap 9, and the opening/closing door 19 and the late-closing trap 9 are opened and the lifting device 12 is operated. The alignment device 13 is transferred onto the guide rail 8a of the overhead crane 6a. Subsequently, this maintenance equipment M13 is removed from the lifting device 12,
While running on this guide rail 8a, the inspection television camera 15 is used to inspect the guide rail 8a.

て作業を続ける。In addition, in the event that the traversing device 7 of the lower overhead crane 6 breaks down [7], the manipulator 14 of the maintenance device '13 performs the work as shown in the figure. If parts need to be replaced, the parts removed by the manipulator 14 can be transported and replaced by the small overhead crane 11 or another small overhead crane lla installed in the cask 10. Maintenance equipment #
13 is working while moving along the guide rail 8a, the traversing device 7a at one end of the guide rail 8a may be placed on the guide rail 8a where it is in standby E-. When the work with the upper overhead crane 6a is finished, the maintenance device 13 is re-lifted (lifted by the I-elevating device 12 and the upper overhead crane 6at is blocked f4).9. The work is continued by moving it from the position directly below and transferring it to the lower overhead crane 6.

る為、安全である。As explained above, in the present invention, the maintenance equipment isolated from the outside is carried into the hot cell from the late closing trap of the hot cell, and is transferred onto the overhead crane in the hot cell, and the traversing cart of this overhead crane runs. This allows for inspection of the guide rail and its surroundings as well as repair and replacement of glazed equipment while traveling on the guide rail.Until now, it has been possible to conduct inspections in the hot cell using existing monitoring equipment in the hot cell, TV cameras on manipulators, etc. Inspections and maintenance work near the overhead crane that cannot be performed with a manipulator can be performed, and reliability is achieved in terms of hot cell maintenance. Defective products that have been replaced are safe because they can be recovered and processed once they are isolated from the outside world.
