Scope: This standard specifies the method summary, reagents and materials, instruments and equipment, samples, analysis steps, result calculation and precision for the determination of total hydrogen in uranium dioxide pellets. This standard applies to the determination of total hydrogen in uranium dioxide pellets, and the mass fraction of hydrogen to be measured ranges from 0.15 μg/g to 20.00 μg/g. When the temperature of UO2 pellets is heated above 2 360 ℃, the consumption of CO oxidant increases significantly. Controlling the heating temperature not to exceed 2 360 ℃ can effectively reduce the consumption of carbon monoxide oxidant under the condition of ensuring complete hydrogen release.
