Gamma Spectrometric Determination of Uranium-235 in Uranium Hexafluoride in 1S and 2S Cylinders

摘要

This report is a continuation of Report K-2021, issued in January 1981. The U-235 isotopic abundances of UF sub 6 at 4% and 0.4% U-235 have been determined in both 1S and 2S cylinders by gamma spectrometry. The source of a positive bias in the 1S-Feed results repoted previously has been eliminated. (ERA citation 07:011407)
