DE-CLADDING MACHINE FOR IRRADIATED NUCLEAR FUEL

摘要

A de-cladding machine for irradiated nuclear fuel is provided to cut a metal nuclear fuel rod or de-clad with a different width by exchanging a bite inside a hot cell. A de-cladding machine for irradiated nuclear fuel includes a base(10), a workpiece clamping unit(20), a workpiece cutting unit(40), a driving unit, and a workpiece depth adjusting unit(60). The workpiece clamping unit(20) is installed on the base(10), and has a plurality of vice units. Metal nuclear fuel rods are fixed on the vice units. The workpiece cutting unit(40) is arranged to face the workpiece clamping unit(20), and has a rotary plate(37) which controls the angles of bites(35). The driving unit has a motor giving a rotary force to the workpiece cutting unit(40). The workpiece depth adjusting unit(60) includes rotary levers(62), a taper rod(65), and a forward/backward movement control unit(70). The taper rod(65) is formed between the rotary levers(62). The forward/backward movement control unit(70) controls the insertion depth of the taper rod(65) between the rotary levers(62).
