Methods of Extracting a Small Quantity of Impurities during Rectification of Uranium Hexafluoride in Fluoride Gas Reprocessing of Spent Nuclear Fuel

Methods for concentrating and extracting a small quantity of volatile impurities of the fluorides of fission products in the rectification method of reprocessing uranium hexafluoride are discussed. Such methods are shown to be efficacious during the operation of experimental and commercial facilities for sublimate and radiochemical operations and in uranium isotope separation plants.
