Standard Test Methods for Chemical, Mass Spectrometric, Spectrochemical, Nuclear, and Radiochemical Analysis of Nuclear-Grade Uranyl Nitrate Solutions

Scope

1.1 These test methods cover procedures for the chemical, mass spectrometric, spectrochemical, nuclear, and radiochemical analysis of nuclear-grade uranyl nitrate solution to determine compliance with specifications.

1.2 The analytical procedures appear in the following order:

Sections Uranium by Ferrous Sulfate Reduction-Potassium 7 to 14 Dichromate Titrimetry Uranium by Ignition Gravimetry 15 to 21 Specific Gravity by Pycnometry 22 to 27 Free Acid by Oxalate Complexation 28 to 34 Thorium by the Arsenazo (III) (Photometric) Method 35 to 42 Chromium by the Diphenylcarbazide (Photometric) Method 43 to 49 Molybdenum by the Thiocyanate (Photometric) Method 50 to 56 Halogens Separation by Steam Distillation 57 to 61 Fluorine by Specific Ion Electrode 62 to 68 Halogen Distillate Analysis: Chloride, Bromide, and Iodide by 69 to 75 Amperometric Microtitrimetry Bromine by the Fluorescein (Photometric) Method 76 to 84 Sulfate Sulfur by (Photometric) Turbidimetry 85 to 92 Phosphorus by the Molybdenum Blue (Photometric) Method 93 to 100 Silicon by the Molybdenum Blue (Photometric) Method 101 to 108 Carbon by Persulfate Oxidation-Acid Titrimetry 109 to 116 Impurities by Emission Spectroscopy 117 to 120 Boron by Emission Spectrography 121 to 127 Impurity Elements by Spark Source Mass Spectrography 128 to 134 Isotopic Composition by Multiple Filament Surface-Ionization 135 to 140 Mass Spectrometry Uranium-232 by Alpha Spectrometry 141 to 147 Total Alpha Activity by Direct Alpha Counting 148 to 154 Fission Product Activity by Beta and Gamma Counting 155 to 161 Entrained Organic Matter by Infrared Spectrophotometry 162 to 174
