Purification of Reprocessed Uranium from 232, 234U in an Additional Product with Feed Point Shifted Toward the Main Product

Atomic Energy Aims and scope

A method of purifying reprocessed uranium hexafluoride from 232, 234U in an additional product of a fourstream cascade is proposed. Shifting the feed point toward the cascade’s main feed stream significantly reduces the concentration of 232, 234U in the additional feed. The main product stream of a four-stream cascade is enriched to 235U concentration 20%. It is subject to dilution to a nuclear safe mixture. A computational experiment was performed on the basis of a procedure for calculating cascades with separation coefficients corresponding to gas centrifuges. It is shown that high-quality low-enriched uranium can be produced from the purified product. It almost meets ASTM C996-15 specifications for 232, 234U for commercial grade uranium hexafluoride.
