Heat Treatment of Degraded Depleted Uranium Metal Chips
摘要
Abstract
Degraded depleted uranium metal chips were converted to the explosion- and fire-safe state by heat treatment. The composition of products obtained by heat treatment of the degraded chips was determined by X-ray diffraction and thermogravimetric analyses. The treatment of the degraded chips stored for more than 5 years in water by successive drying in a thin bed at 200–230°С and high-temperature calcination at 700°С shows much promise. The procedure yields a stable product, triuranium octoxide.
