行）。 For example, as shown in Japanese Patent Publication No. 57-197500, a drum can is filled with radioactive waste pellets, a sodium silicate composition solution as a filler is injected, and the drum is sealed. Yes (Page 5 of the same bulletin, from line 3 in the upper right column to line 5 in the lower left column)

小さい樹脂ペレツト等が浮上してドラム缶上部に
集中する。 In the above-described method, when a sodium silicate composition solution as a filler is injected into a drum filled with radioactive waste pellets, resin pellets with low specific gravity float up and concentrate in the upper part of the drum.
この場合、ドラム缶下部に充填剤のみ層が形成さ

レツトである樹脂ペレツト等には充填剤が十分に
充填されずに固化処理される。In this case, only a layer of filler is formed at the bottom of the drum, while resin pellets, which are radioactive waste pellets, concentrated at the top of the drum are not sufficiently filled with filler and are solidified.
したがつて、作製した放射性廃棄物ペレツトの
固化体は、放射性廃棄物ペレツトに充填剤が均一
に行きわたつていなく分離して充填されている。 Therefore, in the produced solidified body of radioactive waste pellets, the filler is not uniformly spread over the radioactive waste pellets, but is filled in separate pieces.

う欠点があつた。 As described above, since the radioactive waste pellets and the filler are not uniformly arranged, there is a drawback that the strength of the solidified body itself is extremely weak. moreover,
There was a drawback that the lower part of the drum was not sufficiently filled with radioactive waste pellets, and the volume reduction effect of the solidified material was small.

An example of lid production is shown in FIG. First, spheres or sphere-like shapes 1 made of silica or a material with excellent alkali resistance are placed in a cylindrical mold to a certain thickness. Next, a disk-shaped lid 3 is created by adhering to this silica stone or the like with a binder 2 such as cement and a sodium silicate solution. Here, the second
As shown in the figure, in order to form a cavity between adjacent lid-forming base materials and allow the filler to pass through, all the voids in the adjacent lid-forming base materials are filled with binder. Instead, a lid can be created by bonding adjacent spheres or lid-forming base materials having a shape similar to spheres, that is, by bonding only the contact points (adding binder to the extent that the surface of the lid-forming base is wet).

処理処分用容器を形成している。 The weight of the lid 3 used is greater than the buoyancy of the light waste pellets in the filler 2. This lid 3 has a filler penetration channel 6 of irregular shape which allows the filler 2 to pass through but prevents the light waste pellets in the radioactive waste pellets 4 from flowing out. The waste container body 5 and the lid 3 form a container for solidifying and disposing of waste.
