Multi-layered nuclear fuel cladding, according to the present invention, comprises: an inner tube of zirconium alloy, of which both ends are open for providing an accommodation space into which a sintered nuclear fuel pellet is inserted; and an outer tube, disposed coaxially with the inner tube, having a greater diameter than the inner tube so as to surround the outer surface of the inner tube, wherein the outer tube and the inner tube are fixed to closely contact each other, and may be formed from metals different from each other.
