ガスの発生に伴う内圧の上昇により固化不能になったり
、燃焼し難いという問題があるので、処理前に水分を除
去する必要がある。By the way, if waste is treated as it is, such as by reducing its volume and stabilizing it, there are problems such as steam explosions occurring during the treatment, the internal pressure rising due to the generation of steam and gas, making it impossible to solidify, and making it difficult to burn. Therefore, it is necessary to remove water before processing.
ところが、実際には後処理、処分に対する考慮が払われ

。Below, we will explain how to use the drying bag configured as described above. When the waste (B) is placed in the storage container (5) and transported, the water coming out of the waste (B) is filtered through the cylindrical filter (5). 5a), but since the entry port (5d) at the bottom of the storage container (5) is closed by the on-off valve (5b), the water that has passed through this filter (5a) flows into this storage container (5).
There is no leakage from the air, preventing external radiation contamination. When the storage container (5) is housed in the drying container (1), the top 11 (la) of the drying container (1) is closed and sealed, and the opening/closing valve (5b) is connected to the cap fitting (4). This valve (5b) is closed by being pushed by the tip of the mouthpiece (4b).
) is pressed against the lower surface of the storage container (5) by a coil spring (4c), preventing contaminated water from flowing out from the storage container (5) into the drying container (1). be done. Dry capacity 2 of such storage container (5):
(1) During the work of storing the contaminated water inside the drying container (1), the contaminated water that has flowed into the drying container (1) is discharged to the outside from the drain pipe (1c).
次いで、収容容器（５）に収容された廃棄物（ロ）の乾
燥が以下の如くにして行われる。Next, the waste (b) contained in the container (5) is dried in the following manner.
先ず、脱ガス装置（２）の真空ポンプ（２ｃ）を作動さ

ジルコニウム合金になる燃料棒の切断部位が偏平に変形
していても、また細粉であって乾燥ガスの流通性が悪く
ても水分の蒸発が早められるので、それらの内部乾燥を
容易に行い得る。First, the vacuum pump (2c) of the degassing device (2) is operated to degas the inside of the drying container (1). For example, even if the cut part of a fuel rod made of zirconium alloy is deformed into a flat shape, or even if the drying gas has poor circulation due to fine powder, the evaporation of moisture will be accelerated, allowing the internal drying of the fuel rod. can be easily performed.

な活性の強い物質であっても、それらの発火、爆発を容
易に防止することができる。Further, the gas heater (3) is connected to the inert gas supply source (3b).
When heated inert gas is supplied through a), this inert gas flows into the container (5) from the inlet (4a) of the fitting (4) and dries the waste (b). It is possible to easily prevent ignition and explosion of even highly active substances such as cutting residues of fuel rods that become zirconium alloys.
さらに、ヒータ（１ｂ）に電力が投入されることによっ
てもこの廃棄物（ロ）は加熱され乾燥される。Furthermore, this waste material (b) is heated and dried also by supplying electric power to the heater (1b).
このように、３つの乾燥手段の相乗効果によってこれら
の廃棄物０をより効果的に、しかも安全に乾燥させるこ
とができることとなる。In this way, the synergistic effect of the three drying means makes it possible to dry these waste materials more effectively and safely.
なお、上記実施例は本発明の一具体例にすぎず、従って
本実施例によって本発明の技術的思想の範囲が限定され
るものではない。It should be noted that the above embodiment is only one specific example of the present invention, and therefore the scope of the technical idea of the present invention is not limited by this embodiment.
本発明によれば、収容容器に入れて被処理体を移動する
に際しては、この被処理体から出る水はフィルタをとお
るが、収容容器の底部の突入口が開閉弁で閉弁されてい
るので、フィルタをとおった水がこの収容容器から流出
することがない。According to the present invention, when the object to be processed is moved in the container, the water coming out of the object passes through the filter, but the inlet at the bottom of the container is closed by the on-off valve. , water that has passed through the filter will not flow out of this container.
次いで、収容容器が乾燥容器に入れられると、乾燥容器
が密封されると共に、開閉弁が口金具で押されてこの弁
が開く一方、口金具に外嵌されているシート座が弾発体
により収容容器の底面に押圧され、収容容器からの水の
流出が防止されるので、汚染物質の散逸が防止されるこ
ととなる。Next, when the storage container is placed in the drying container, the drying container is sealed and the opening/closing valve is pushed by the cap fitting to open this valve, while the seat seat fitted on the cap fitting is pressed by the elastic body. Since it is pressed against the bottom surface of the storage container and water is prevented from flowing out from the storage container, the dissipation of contaminants is prevented.
そして、脱ガス装置を作動させれば乾燥容器内の脱ガス

発が促進され、しかも加熱した不活性ガスにても乾燥さ
れるので、発火、爆発し易い被処理体であっても発火、
爆発等の発生の恐れがなく、安全な乾燥処理作業が可能
になる。When the degassing device is activated, the inside of the drying container is degassed, which accelerates the evaporation of water even in conditions with poor ventilation, and it also dries even with heated inert gas. , ignition, even if the object is easily ignited or exploded.
Safe drying operations can be performed without the risk of explosions or the like.
さらに、この被処理体はヒータによっても加熱されるの
で、各乾燥手段の相乗効果により被処理体をより効果的
に乾燥させることができ、その効果は極めて大である。Furthermore, since the object to be processed is also heated by the heater, the object to be processed can be dried more effectively by the synergistic effect of each drying means, and the effect is extremely large.
