AN COATING APPARATUS FOR INNER SURFACE OF NUCLEAR FUEL CLADDING

摘要

PURPOSE: A device for coating the inner surface of a nuclear fuel cladding tube is provided to reduce the manufacturing costs of a nuclear fuel cladding tube by recycling graphite materials from the nuclear fuel cladding tube. CONSTITUTION: A cladding tube receiving unit(10) receives a nuclear fuel cladding tube. A feed unit(20) supplies graphite solutions to an implantation unit. An implantation unit(30) includes a grid plate. The implantation unit implants the graphite solution into the inner surface of the nuclear fuel cladding tube through a penetration hole. A recovery unit(40) comprises a recovery plate and a recovery device. The recovery plate collects the graphite solution outputted from the grid plate and the cladding tube receiving unit. The recovery device transmits the graphite solution collected by the recovery plate to the supply unit.
