PURPOSE:To remove the cladding by being grinded into pieces by thermal shock, by means of rapid cooling the fuel pin by liquid Helium. CONSTITUTION:After a plenum 3a of a fuel pin 3 being mounted on a supporting tool 4 by means of opening a disk 2 of opeining/ closing, the fuel pin is sealed. Liquid Helium is filled up to the fulfilling into a super electric condutive magnet 1 by means of driving a pump 7, and the fuel cladding tube is grinded into pieces by the rash cladding tube is grinded into pieces by the rash termal shock, and the trash of the crushed cladding tube is allowed to be absorbed by magnetcically at the inner surface of the super electric conductive magnet 1. The fuel pellet is deposited at the bottom of the super electric conductive magnet 1. The mixed solution of the liquid Helium and the fuel pellet is allowed to be flowed out into a precipitation tank 11 by means of opening a valve 12. Another trash of the cladding tube is allowed to be dropped on a conveyer 15 from a valve device 8 by means of eliminating the magnetc field. |
