【発明の詳細な説明】 （関連技術分野） 本発明は、原子力発電所で発生する放射性物質で汚染さ
れた雑固体廃棄物の減容処理方法に関するものである。Description: TECHNICAL FIELD The present invention relates to a method for reducing the volume of miscellaneous solid waste contaminated with radioactive substances generated in a nuclear power plant.
（従来技術） 放射性物質で汚染された雑固体廃棄物は従来より２００
ドラム缶に入れて保管されているが保管スペースに問
題がある。(Prior Art) Miscellaneous solid waste contaminated with radioactive materials has been
It is stored in a drum, but there is a problem with the storage space.
このため、雑固体廃棄物を入れたドラム缶を圧縮減容
し、この減容された数個の廃棄物を別の新しいドラム缶
に入れて保管することが考えられている。Therefore, it is considered to compress and reduce the volume of a drum containing miscellaneous solid waste and store the volume-reduced several wastes in another new drum.
これを可能にするためには、廃棄物の入ったドラム缶の

る。To make this possible, it is necessary to reduce the diameter of waste drums. As one of the proposals, the inner peripheral surface of the compression sleeve is a compression sleeve including an upper large diameter portion, a lower small diameter portion, and an intermediate taper portion, and the inner peripheral surface of the compression sleeve is formed at the peripheral portion of the press ram. A large number of vertical grooves that engage with a large number of ridges are recessed, and a cylindrical container filled with solid waste is stored in the large diameter part of the upper part of the compression sleeve, and the vertical direction of the inner peripheral surface of the compression sleeve is stored. When the press ram is lowered by engaging the protrusion of the peripheral edge of the press ram with the groove, the cylindrical container inside the large diameter part of the compression sleeve is pressed downward together with the solid waste inside it, while passing through the taber part. Receives a compressive force from the entire circumference toward the center and reduces the outer diameter to the lower small diameter portion where it is finally pressed by the press ram at high pressure to reduce its vertical height by a fraction. What was made to be reduced to compression volume It is.

重大な欠点がある。焼付きを生じさせないように、ドラ
ム缶のプレスラム側が圧縮スリーブのテーパ部を通過す
る時、移動速度を極めて遅い速度にしなければならず、
速度制御系が極めて高価な装置となる不都合がある。However, this presses the cylindrical container (drum can) housed in the compression sleeve with the press ram, so the drum can is deformed (compressed volume reduction) under the condition that the press ram side end is blocked by the press ram, and There is a serious defect that seizure occurs on the inner peripheral surface of the compression sleeve on the side of the press ram and it becomes inoperable. When the press ram side of the drum can passes through the taper part of the compression sleeve, the moving speed must be extremely slow so as not to cause seizure.
There is a disadvantage that the speed control system becomes an extremely expensive device.
このように廃棄物の入ったドラム缶の径方向への絞り込
み技術はまだ完成されていないのが実状である。As described above, the technology for narrowing down the drums containing waste in the radial direction has not been completed yet.
（考案の解決しようとする問題点） 本発明は上記に鑑みてなされたもので、廃棄物を入れた
ドラム缶を、別の新しいドラム缶に収納可能に圧縮減容
する方法を提供することにある。(Problems to be Solved by the Invention) The present invention has been made in view of the above circumstances, and an object thereof is to provide a method of compressing and reducing the volume of a drum containing waste to be stored in another new drum.

からなることを特徴とする。(Means for Solving Problems) Teeth are arranged radially in the circumferential direction of the drum can, and a pressing drive device is provided for each, and the teeth are pressed by the pressing drive device to deform the outer periphery of the drum can into a petal shape. And the step of reducing the diameter of the drum can, and the step of inserting the drum reduced in the inside diameter of the drum in the container into the container and compressing the drum in the axial direction of the drum with a punch.
