Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、放射性廃棄物処理体に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a radioactive waste processing body.
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
同化材を充填し、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 assimilation 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、かつ固化材に
よる１貴増加も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処理できない欠点がある。However, in this proposal, since the entire weight of the large radioactive waste treatment container is large, and the increase in waste due to the solidification material is also large, there is a drawback that, for example, it cannot be handled with conventional handling equipment during transportation. be.
本発明者は、前記の問題点に対する研究を進めた結果、
放射性廃棄物処理体の構成を、容器状の気泡コンクリー

とすれば、前記の問題点を解決できることを見い出した
。As a result of research into the above-mentioned problems, the inventor has found that
The structure of the radioactive waste treatment body is such that radioactive waste is placed in a container-shaped container-shaped aerated concrete body or lightweight concrete body with a thin dense layer on the surface, and the radioactive waste is placed in a container made of solidifying materials and foaming materials. It has been found that the above problems can be solved by solidifying and filling with a solidifying material containing.
すなわち、容器状の気泡コンクリート体又は軽量コンク
リート体の表面に緻密な層を薄く設けた放射性廃棄物処
理用容器は、体積の割りには重量が比較的軽いものであ

性材料のみではなく起泡性材料を含むものであるから、
体積の割りには軽量なものであり、従って本発明の放射
性廃棄物処理体を処理場に搬送して陸地処分するに際し
テ従来のハンドリング装置で充分に取り扱え、輸送費を
安いものとでき、極めて経済的である。In other words, a container for radioactive waste disposal, which is a container-shaped aerated concrete body or lightweight concrete body with a thin dense layer on the surface, is relatively light in weight compared to its volume, and is also suitable for storing radioactive waste. The solidifying material for solidifying and filling includes not only solidifying materials but also foaming materials.
It is lightweight relative to its volume, and therefore, when the radioactive waste treatment bodies of the present invention are transported to a treatment plant and disposed of on land, they can be sufficiently handled with conventional handling equipment, and transportation costs can be kept low. Economical.
又、放射性廃棄物を固化する為に用いられる固化材は流
動性が良く、放射性廃棄物処理用容器内に均一に充填さ
せることができ、従って得られる固化体と放射性廃棄物
処理用容器との間に不必要な大きな空隙が生じる恐れが
なく、大きな空隙があった為にそれだけ強度が弱くなる
といった欠点が起きなくなる。In addition, the solidifying material used to solidify radioactive waste has good fluidity and can be filled uniformly into the radioactive waste processing container, making it possible to mix the resulting solidified material with the radioactive waste processing container. There is no risk of unnecessary large voids being created between the two, and the drawback that the strength is weakened due to the presence of large voids does not occur.
さらには、気泡を有する構造のものであるから、凍結融
解にも強く、そしてこの気泡が独立気泡タイプのもので
ある場合には、放射性物質の滲出はより一層少ないもの
である。Furthermore, since it has a structure with bubbles, it is resistant to freezing and thawing, and if the bubbles are of a closed cell type, leakage of radioactive substances is even less.
