摘要： An improved process for recovering irradiated nuclear reactor fuel material is disclosed. This process includes the steps of extracting uranium, plutonium and neptunium from a solution of irradiated fuel, passing this stream to a reflux column, where a high saturation of uranium is maintained. Separation of uranium from plutonium and neptunium, and further decontamination of uranium results from this high saturation. This process is simple, has a high recovery efficiency and high decontamination, uses relatively small amounts of process reagents and produces a relatively small volume of radioactive waste material.
