APPARATUS FOR DISMANTLING OF SPENT NUCLEAR FUEL ASSEMBLY

摘要

PURPOSE: An apparatus for disassembling a spent nuclear fuel assembly is provided to install a drawing device in the spent nuclear fuel assembly by lifting a holding unit when drawing out the spent nuclear fuel rod. CONSTITUTION: A support(100) includes a base plate, a bottom plate, a pair of vertical columns, a support plate and a top plate. A pair of bearings are installed in the base plate. The bottom plate is combined with a support shaft of the bearings. The vertical columns are coupled on the bottom plate. The support plate connects the vertical columns. The top plate is coupled on the vertical columns. A driver(200) is combined in the support. A holding unit(300) holds the spent nuclear fuel assembly and moves up and down by the driver. A transfer unit guides the movement of the holding unit. A drawing unit draws out the spent nuclear fuel rod from the spent nuclear fuel assembly. The controller controls the operation of the driver according to the position of the holding unit.
