标准摘要
[中文适用范围]： 本国际标准描述了测量 UO2 和 PuO2 粉末（高达 2000 µg/g 氧化物）以及 UO2 和 (U,Gd)O2 和 (U,Pu)O2 颗粒（高达 10 µg/g 氧化物）总氢含量的程序。 克氧化物）。 总氢含量由吸附水、结晶水、碳氢化合物和其他可能作为杂质存在于燃料中的氢化化合物产生。 [外文原描述]： ISO 15651:2015 describes a procedure for measuring the total hydrogen content of UO 2 and PuO 2 powders (up to 2 000 µg/g oxide) and of U0 2 and (U,Gd)O 2 and (U,Pu)O 2 pellets (up to 10 µg/g oxide). The total hydrogen content results from adsorbed water, water of crystallization, hydro-carbon, and other hydrogenated compounds which can exist as impurities in the fuel.
