A nuclear fuel rod cladding having a burnable absorber integrally incorporated therein has an outer tubular layer of a zirconium alloy; an intermediate layer, of a thickness less than the outer tubular layer, of a zirconium alloy containing a boron-containing burnable absorber; and an inner layer, of a thickness less than the intermediate layer, of zirconium metal. The layers are bonded together to form a cladding for the containment of nuclear fuel.

A nuclear fuel cladding having a predetermined concentration of burnable absorber integrally incorporated therein, for use in containing a nuclear fuel in a reactor, the cladding formed as a hollow composite tube comprising: an outer tubular layer, having a first thickness of at least 15 mils, consisting essentially of a first zirconium alloy; an intermediate layer bonded to the inner wall of said outer tubular layer, having a second thickness less than said first thickness, consisting essentially of a mixture of a boron-containing material having a predetermined enrichment of boron and a second zirconium alloy, said second thickness being defined by said predetermined enrichment of boron in said boron-containing material and by the predetermined concentration of burnable absorber incorporated into said fuel cladding; and an inner layer of zirconium metal, having a third thickness less than said second thickness, bonded to said intermediate layer, said third thickness being sufficient to isolate said intermediate layer from said nuclear fuel.
