Abstract
A process is provided involving the use of hydrogen for the separation of uranium and plutonium and mixtures thereof, from composite substances and assemblies or mixtures containing metallic and ceramic components where the metallic component is zirconium or a zirconium alloy and the ceramic component contains uranium and/or plutonium.
Claims4
A method of separation of a ceramic component which is a compound of uranium, plutonium or uranium and plutonium from a metallic component is zirconium or an alloy consisting essentially of zirconium and containing minor amounts of tin, iron, chromium, or niobium or combinations thereof comprising the steps of contacting composites, assemblies or mixtures containing said components with hydrogen at a temperature of from about 200.degree. C to 700.degree. C at about 1-100 atmospheric pressure to form brittle zirconium hydride and separating said zirconium hydride from the chemically unchanged ceramic component.
