The present invention provides a cladding having an outer circumferential substrate, a zirconium barrier layer metallurgically bonded to the inside surface of the substrate and an inner circumferential liner metallurgically bonded to the zirconium barrier. The inner circumferential liner is more ductile than conventional Zircaloy. The low ductility of the inner circumferential liner is obtained by using a zirconium alloy containing a low tin content (e.g. less than 1.2% by weight) and/or a low oxygen content (e.g. less than 1000 ppm). The inner circumfer...
A method of making a cladding tube having an outer substrate, an intermediate zirconium barrier layer, and an inner liner, the substrate, barrier layer, and inner liner each having interior and exterior circumferential surfaces, the method comprising the following steps: (a) bonding the zirconium barrier layer exterior circumferential surface to the substrate interior circumferential surface; and (b) bonding the inner liner outer circumferential surface to the zirconium barrier layer inner circumferential surface, wherein the inner liner comprises a zirc...
