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 [Field of Industrial Application] 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固化材を充填し、固化さ

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、かつ固化材による重量増加も大きなものであ

置で処理できない欠点がある。 However, in this proposal, the weight of the large radioactive waste processing container as a whole is large, and the weight increase due to the solidification material is also large, so there is a drawback that it cannot be processed using conventional handling equipment during transportation, for example. .

記の問題点を解決できることを見い出した。
As a result of conducting research on the above-mentioned problems, the present inventor has developed a radioactive waste processing body for radioactive waste processing in which a thin dense layer is provided on the surface of a container-shaped aerated concrete body or lightweight concrete body. It has been found that the above-mentioned problems can be solved by solidifying and filling radioactive waste in a container with a solidifying material containing a solidifying material and a foaming material.

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、従つ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て
従来のハンドリング装置で充分に取り扱え、輪送
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. Since the solidification material for solidification and filling includes not only solidification material but also foamable material, it is lightweight in relation to its volume. When disposing on land, it can be handled satisfactorily with conventional handling equipment, transportation costs can be kept low, and it is extremely 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

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
あつた為にそれだけ強度が弱くなるといつた欠点
が起きなくなる。 In addition, the solidifying material used to solidify radioactive waste has good fluidity and can be uniformly filled into the container for radioactive waste treatment. There is no risk of unnecessary large voids being created between the two, and the drawbacks that occur when the strength is weakened due to large voids will not occur.

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.
