本発明は、核燃料ペレットの装填装置に係り、特に核燃
料ペレットを容易に被覆管に装填できるようにした核燃
料ペレットの装填装置に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a nuclear fuel pellet loading device, and more particularly to a nuclear fuel pellet loading device that allows nuclear fuel pellets to be easily loaded into a cladding tube. Regarding.
（従来の技術および発明が解決しようとする課題）
一般に、核燃料ペレットはチャンファ−と呼ばれる面取
り加工がされ、その直径が１．０．３＋＋ｕｉ程度の大
きさに形成されている。(Prior Art and Problems to be Solved by the Invention) Generally, nuclear fuel pellets are chamfered to have a diameter of about 1.0.3++ ui.
また、この核燃料ペレットを装填する被覆管は、金属製
で内径か１０．５ｍｍ、長さが４．０００ｍｍの細くて
長い中空管で構成されている。The cladding tube into which the nuclear fuel pellets are loaded is a long, thin hollow metal tube with an inner diameter of 10.5 mm and a length of 4.000 mm.

とえ加工かできても孔が小さいので空気を十分に速く逃
がすことがきす実状に適さない。Nuclear fuel pellets are normally loaded into this thin cladding tube using a pusher rod or the like in the atmosphere. In this case, when the fuel pellet is pushed into the cladding tube, the gap between the fuel pellet and the cladding tube is about 0.21 mm, so as the fuel pellet is pushed into the cladding tube, the tip of the cladding tube The air may be blocked by the fuel pellet and stagnate, reducing the pushing speed, or work efficiency. Therefore, as an improvement measure, it was considered to create a hole in the center of the nuclear fuel pellet and pusher rod to allow air to escape, but since the diameter of the nuclear fuel pellet and pusher rod is small, it is difficult to perform such processing. Even if it could be machined, the holes would be too small to allow air to escape quickly enough, making it unsuitable for the actual situation.

題かあった。Also, in this method, when loading nuclear fuel pellets, the nuclear fuel pellets are dropped into the cladding tube, so the nuclear fuel pellets that were previously loaded...!
There was a problem of chipping or the first place of hitting the ground.
