ActiveDetermination of gadolinium，samarium，dysprosium and europium in uranium dioxide powders and pellets by horizontal ICP-AES
二氧化铀粉末和芯块中钆、钐、镝和铕的测定 水平式ICP-AES 法
Application Summary AI generated
This standard specifies a method for determining the concentrations of gadolinium, samarium, dysprosium, and europium in uranium dioxide (UO₂) powders and pellets using horizontal inductively coupled plasma atomic emission spectrometry (ICP-AES). It is applied in the nuclear fuel industry for quality control and material characterization, specifically to verify the composition of UO₂ fuel used in nuclear reactors. The standard ensures accurate measurement of these rare earth elements, which act as neutron poisons or impurities affecting fuel performance.
