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.
