Abstract

Uranium metal is hardened by forming a dispersion of UO2 in the metal matrix, the method used comprising preparing finely-divided UH3 from the metal, treating the hydride with small amounts of oxygen to coate the particles with UO2, heating to decompose the hydride to metal, and then treating again with oxygen. Uranium metal in lump or shot form may be treated at 400 DEG -690 DEG F. with dry hydrogen to form UH3, which may be reconverted to metallic uranium and the process repeated to yield a hydride product of size 0.5 to 20 microns. Argon is then passed into an agitated bed of the hydride and calibrated amounts of oxygen are admitted at ambient temperature to 250 DEG F. Hydrogen is then removed by heating in vacuum at 600 DEG -700 DEG F. and more oxygen is introduced as before to a desired UO2 content in the range 1 to 30% by volume. The uranium-UO2 powder mixture is hot or cold pressed and extruded at 1500 DEG -1700 DEG F. under a pressure of 10,000 to 22,000 pounds per square inch to form a product useful as nuclear fuel.
