Abstract
Method for conditioning metallic waste shells of zirconium or zirconium alloys obtained during processing of irradiated nuclear reactor fuel elements for noncontaminating final storage. The waste shells are subjected to a controlled oxidation at increased temperature to produce noncombustible, stable waste products which consist substantially of zirconium dioxide. The noncombustible, stable waste products so-produced are brought to final storage.
