ABSTRACT:
Zirconium-based corrosion resistant alloys are provided primarily for use as a cladding material for fuel rods in a boiling water nuclear reactor, the alloy in one embodiment consisting essentially of about 0.5-2.0 percent by weight of tin, about 0.5-1.0 percent by weight of a solute, the solute being composed of a member selected from the group consisting of molybdenum, tellurium and mixtures thereof, or alternatively, the solute will contain niobium in combination with molybdenum and/or tellurium and the remainder being zirconium, and in another embodiment the alloy consists essentially of about 0.5-2.0 percent by weight of tin 0.3-1.4 percent by weight of a solute, the solute being composed of tellurium, and the remainder being zirconium.
