〔産業上の利用分野〕
本発明は、放射性廃棄物処理用容器に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a container for treating radioactive waste.
例えば、放射性廃棄物をセメント等の固化材で固化して
充填したドラム缶複数個を一つの大きな放射性廃棄物処
理用容器に入れ、この放射性廃棄物処理用容器の隙間に
固化材を充填し、固化させ、これを所定の処理場に搬送
して陸地処分することが考えられている。For example, multiple drums filled with radioactive waste solidified with a solidification material such as cement are placed in one large radioactive waste treatment container, and the solidification material is filled into the gaps between the radioactive waste treatment containers and solidified. The idea is to transport the waste to a designated treatment plant and dispose of it on land.
しかし、この提案においては、大きな放射性廃棄物処理
用容器全体の重量が大きなものである為、例えば搬送に
際して従来のハンドリング装置で１７】部に放射性廃棄
物が充填されている大きな放射性廃棄物処理用容器を処
理できない欠点がある。However, in this proposal, since the entire weight of a large radioactive waste disposal container is large, for example, when transporting a large radioactive waste disposal container filled with radioactive waste, it is difficult to use conventional handling equipment. There is a drawback that containers cannot be processed.
本発明は前記の問題点に鑑みてなされたものであり、容

The container body 1 has a size of 1 m, and the inner surface of the container body 1 is coated with, for example, P-G material having a thickness of 0.1 to 5 cr.

属板等緻密な組織を持つ層２が一体的に設けられている
。A layer 2 having a dense structure such as GRC, FRP, engine concrete, polyethylene, resin such as vinyl chloride resin, metal plate such as stainless steel plate, etc. is integrally provided.
尚、容器本体１の形状は立方体に限られることなく、円
筒形その他任意の形のものでよい。Note that the shape of the container body 1 is not limited to a cube, and may be any other shape such as a cylinder.

密な組織を持つ層４が一体的に設けられている。Reference numeral 3 denotes a 1.5 cm thick lid made of the same material as the container body 1, for example, aerated concrete. A layer 4 having a dense structure and made of the same constituent material as the layer 2 having a dense structure is integrally provided.
周、上記緻密な組織を持つ層２，４は、容器本体１及び
蓋体３の内面側ではなく、外面側に設けるようにしても
よく、又、内面側と外面側の両方に設けるようにしても
よい。The layers 2 and 4 having a dense structure may be provided on the outer surface of the container body 1 and the lid 3 instead of on the inner surface, or may be provided on both the inner and outer surfaces. It's okay.
上記のように放射性廃棄物をセメント等の固化材で固化
充填したドラム缶を複数個入れる為の放射性廃棄物処理
用容器が構成されていると、この容器は大型なものであ
るにもかかわらず普通コンクリート（比重約２．３）に
よる場合よりも軽量であり、この容器による重量増加分
は比較的少なく、従って搬送等に際して従来のノ・ンド
リング装置で取り扱える。As mentioned above, if a radioactive waste disposal container is configured to hold multiple drums filled with radioactive waste solidified with a solidifying material such as cement, this container is usually large in size. It is lighter than concrete (specific gravity approximately 2.3), and the added weight of the container is relatively small, so it can be handled by conventional no-undling equipment during transportation and the like.
又、放射性廃棄物処理用容器の容器本体１及び蓋体３は
、例えば気泡コンクリートといった素材で構成されてい
るから、凍結融解に強く、シかもこれに緻密な組織を持
つ層が一体的に設けられているから、水等が内部に入り
込むことはなく、又、放射性物質が外部に滲出すること
を効果的に防止できる。In addition, since the container body 1 and the lid 3 of the container for radioactive waste treatment are made of a material such as aerated concrete, they are resistant to freezing and thawing, and a layer with a dense structure is integrally provided thereon. This prevents water from entering the inside and effectively prevents radioactive substances from leaking outside.
冑、蓋体３は、プレキャストコンクリート又は高密度後
打コンクリート等によるものでもよい。The helmet and lid 3 may be made of precast concrete or high-density post-cast concrete.

ない等の特長を有する。The container for radioactive waste disposal according to the present invention is a container-shaped aerated concrete body or lightweight concrete body with a thin dense layer on the surface, so even if the size of the container increases, it is relatively light and lightweight. Therefore, a plurality of drums filled with radioactive waste solidified with a solidifying material such as cement are placed in this container, and a solidifying material such as aerated concrete or aerated cement glass is filled and solidified into the gap. When transported to a processing plant and disposed of on land, it can be handled satisfactorily using conventional handling equipment, transportation costs can be kept low, it is economical, and it is resistant to freezing and thawing, making it highly durable. Furthermore, it has features such as no leakage of radioactive substances.
