GB/T 13698-2015 in English

《GB/T 13698-2015二氧化铀芯块中总氢的测定》由TC58（全国核能标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了二氧化铀芯块中总氢测定的方法提要、试剂和材料、仪器设备、试样、分析步骤、结果计算及精密度。
本标准适用于二氧化铀芯块中总氢的测定,测量氢的质量分数范围为0.15μg/g~20.00μg/g。加热二氧化铀芯块温度超过2360 ℃时,一氧化碳氧化剂的消耗量显著增加。在确保氢释放完全的情况下控制加热温度不超过2360 ℃能有效减少一氧化碳氧化剂的消耗。

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.
