1.1 These test methods cover procedures for the chemical, mass spectrometric, and spectrochemical analysis of nuclear-grade uranium dioxide powders and pellets to determine compliance with specifications.
1.2 The analytical procedures appear in the following order:
Sections Uranium by Ferrous Sulfate Reduction in Phosphoric Acid and 7 to 15 Dichromate Titration Method Uranium and Oxygen Uranium Atomic Ratio by the Ignition 16 to 22 (Gravimetric) Impurity Correction Method Carbon (Total) by Direct Combustion-Thermal Conductivity 23 to 32 Method Total Chlorine and Fluorine by Pyrohydrolysis Ion-Selective 33 to 39 Electrode Method Moisture by the Coulometric, Electrolytic Moisture Analyzer 40 to 47 Method Nitrogen by the Kjeldahl Method 48 to 55 Isotopic Uranium Composition by Multiple-Filament Surface- Ionization Mass Spectrometric Method Spectrochemical Determination of Trace Elements in High-Purity 56 to 63 Uranium Dioxide Silver, Spectrochemical Determination of, by Gallium Oxide 64 to 65 Carrier D-C Arc Technique Rare Earths by Copper Spark-Spectrochemical Method 66 to 75 Impurity Elements by a Spark-Source Mass Spectrographic 76 to 82 Method Surface Area by Nitrogen Absorption Method 83 to 89 Total Gas in Reactor-Grade Uranium Dioxide Pellets 90 to 97 Thorium and Rare Earth Elements by Spectroscopy 98 to 105 Hydrogen by Inert Gas Fusion 106 to 115 Uranium Isotopic Analysis by Mass Spectrometry 116 to 124
