Abstract
The economics of nuclear fuel management must be ultimately based on uranium analyses. Many uranium-bearing materials have a high monetary value and ever- increasing quantities are involved both domestically and internationally, so that precise and accurate determinations of the uranium content assume considerable importance. Since purities and uranium concentrations of nuclear material samples are widely divergent, many different standard analytical procedures often must be used to satisfy specific needs. Sometimes, however, new procedures must be developed. Several of these procedures are presented from the standpoint of their improved precision and accuracy or rapid sample processing. These analytical procedures can be applied to the uranium determinations of uranium hexafluoride samples at all isotopic assay levels, to recovered uranium compounds returned from licensees, to uranium-bearing waste solids and solutions, and to umpire samples to resolve analytical discrepancies between laboratories.
