NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical with ISO 7476 : 2003 ‘Nuclear fuel technology - Determination of uranium in uranyl nitrate solutions of nuclear grade quality — Gravimetric method’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of

Indian Standards on recommendation of the Nuclear Energy for Peaceful Applications Sectional Committee and approval of the Chemical Division Council.

This Indian Standard is published in four parts. The other parts in this series are:

Part 1 Determination of uranium in solutions, uranium hexafluoride and solids - Iron (II) reduction/potassium dichromate oxidation titrimetric method

Part 2 Determination of uranium in solutions, uranium hexafluoride and solids - Iron (II) reduction/cerium (IV) oxidation Titrimetric method

Part 4 Determination of the isotopic and elemental uranium and plutonium concentrations of nuclear materials in nitric acid solutions by thermal-ionization mass spectrometry
