ActiveMethods for analysis of uranium ore concentrate—Part 11：Determination of thorium—Inductively coupled plasma mass spectrometry
铀矿石浓缩物分析方法 第11部分：钍的测定 电感耦合等离子体质谱法
Application Summary AI generated
This standard specifies the use of inductively coupled plasma mass spectrometry (ICP-MS) for determining thorium content in uranium ore concentrate. It is applied in the nuclear fuel cycle industry, specifically for quality control and material accounting at uranium processing facilities. The method ensures accurate measurement of thorium impurities, which is critical for meeting regulatory purity requirements and preventing interference in downstream uranium enrichment or fuel fabrication.
