Corrosion resistant composite claddings for nuclear fuel rods
This paper describes a corrosion resistant nuclear fuel element. It comprises: an elongated composite cladding container having a zirconium alloy tube consisting essentially of by weight percent; 0.5 to 2.0 percent tin, 0.2 to 1.5 percent of a solute composed of molybdenum and tellurium and the balance zirconium, the container having a barrier layer of sponge zirconium metallurgically bonded to the inside surface of the alloy tube, the sponge zirconium being about 1 to 30 percent of the thickness of the alloy tube; and a central core of a body of nuclear fuel material selected from the group consisting of compounds of uranium, plutonium, thorium and mixtures thereof disposed in and partially filling the container so as to leave a gap between the container and the core and an internal cavity at one end of the container, an enclosure integrally secured and sealed at each end of the container and a nuclear fuel material retaining means positioned in the cavity.
