Metal containers such as drums and containers lined with concrete are generally used, and radioactive waste is filled inside, hardened with cement, etc., and then placed inside a concrete pit in an uninhabited area. Final land disposal with storage is being considered. However, as shown in, for example, Japanese Utility Model Application Publication No. 63-199100, all of these conventional disposal containers have wide mouths, so it is necessary to perform extensive lid-jointing after filling the contents. As a result, it was not possible to fill the container to its entire internal capacity, creating gaps between the contents and the lid, and the drawback was that the storage capacity, which is the storage capacity relative to the overall container capacity, was low. .

The object of the present invention is to provide a disposal container for powdery radioactive waste that can be significantly improved.

2 is a ceramic inner container housed therein. This ceramic inner container 2 has a wall thickness of, for example, 10 mm.
It is approximately 15 mm in diameter, and a small-diameter injection port 3 is formed at its upper part. The injection port 3 may be large enough to inject powdery radioactive waste and a kneaded material such as cement, asphalt, or polymer, and should have a diameter of about 60 to 80 mm.
If it is less than 60 mm, it is difficult to inject the kneaded material, and if it exceeds 80 mm, the advantage of having the injection port 3 with a small diameter diminishes. 4 is a sealing member for sealing this injection port 3. Although it is preferable to use a ceramic plug as shown in the drawing as the sealing member 4, any other type of cap may be used.

充填を可能とするためである。 The top plate 2b around the injection port 3 is inclined conically toward the injection port 3. This is to increase the efficiency of filling the contents by gradually filling the kneaded material toward the injection port 3, and ultimately to enable filling with a volume ratio of 100%.

A fixing material 5 such as mortar having a thickness of about 10 mm to 15 mm is filled in the gap between the ceramic inner container 2 and the ceramic inner container 2. If the thickness of the fixing material 5 is less than 10 mm, the impact resistance will be lowered, and if it exceeds 15 mm, the capacity storage rate will be lowered, which is not preferable. In addition, it is preferable that the upper surface of the inner ceramic container 2 is also filled with an upper fixing material 6 such as mortar.

ととなる。(Function) The disposal container of the present invention configured as described above is a ceramic inner container in which a mixture of powdery radioactive waste 10 and cement, asphalt, polymer, etc. is fixed in advance inside the metal container 1. The injection port 3 is injected through the small-diameter injection port 3 of No. 2, and after solidification is completed, the injection port 3 is sealed with a sealing member 4, and the upper part is filled with an upper fixing material 6 such as mortar, and the lid is tightened. Therefore, it will be stored for a long time in this state.

険を防止するうえで効果的なものである。 In this way, in the disposal container of the present invention, the injection port 3 of the ceramic inner container 2 has a small diameter of 60 to 80 mm, so it is sufficient to use a small sealing member 4 to seal it. be. Therefore, the length of connection with the sealing member 4 is also extremely short, and leakage of the contents can be reliably prevented. In addition, in the disposal container of the present invention, the top plate 2b of the ceramic inner container 2 is inclined conically toward the injection port 3, so that it is possible to fill the kneaded material up to the mouth toward the injection port 3. The contents can be filled to nearly 100% of the container's total capacity. In particular, containers made in a conical shape can be filled 100%, making it possible to significantly improve the capacity storage rate. In addition, the disposal container of the present invention encloses the powdery radioactive waste 10 inside the non-water permeable ceramic inner container 2 with a fixing material 5 such as mortar with a thickness of about 10 mm to 15 mm, so it can be used for a long period of time. Even if the outer metal container 1 is corroded during storage, the risk of radioactive substances leaking to the outside can be eliminated. This fixing material 5 is effective in preventing the danger of damage to the ceramic inner container 2 due to external impacts or the like.

めて大きいものである。(Effects of the invention) As explained above, the present invention uses a ceramic inner container that has a small-diameter injection port and a top plate around it that is tilted conically toward the injection port to be used as a metal container. By storing the waste inside, the storage capacity of powdery radioactive waste is greatly improved, and the risk of leakage of radioactive materials to the outside is prevented. Therefore, by using the disposal container of the present invention, storage space can be used efficiently and a large amount of powdery radioactive waste can be stored. Therefore, the present invention has extremely great practical value as a disposal container for powdery radioactive waste that eliminates the problems of the conventional method.
