Abstract: PURPOSE: A zirconium-ceramic hybrid tube for a nuclear fuel rod coating pipe and a manufacturing method thereof obtain the excellent ductility and low absorption properties of zirconium and the excellent heat resistance and corrosion resistance properties of ceramic by forming the zirconium-ceramic hybrid tube in a multi-layer structure of a zirconium tube and a ceramic tube. CONSTITUTION: A zirconium-ceramic hybrid tube (10) has a two-layer structure of a zirconium tube (11) and a fiber type ceramic tube (12). The ceramic tube is composed of fiber type ceramic or monolithic ceramic. The zirconium tube is composed of zirconium or a zirconium alloy. One or more ceramic tubes and one or more zirconium tubes form a multi-layer structure by being successively laminated in a concentric form. A graphite tube is interposed between the ceramic tube and the zirconium tube.
