Abstract: Accurate and rapid analysis of element content in uranium-based nuclear fuel pellet is crucial for the quality control of nuclear fuel.In this paper,the analysis methods for major metals,micro-trace metals and non-metallic impurity elements in uranium-based nuclear fuel pellet in recent years are reviewed from 3 aspects,including sample pretreatment,matrix separation and composition determination.The sample pretreatment methods mainly include acid dissolution,microwave digestion and direct pressed pellet.The matrix separation methods mainly include levextraction,extraction separation,liquid-solid phase separation method and high-temperature hydrolysis(PH).The composition determination methods mainly include titration,X-ray fluorescence spectrometry(XRF),inductively coupled plasma optical emission spectrometry(ICP-OES/AES),inductively coupled plasma mass spectrometry(ICP-MS),pulse melting thermal conductivity method,ion chromatography,oxidative combustion method,spectrophotometry and ion selective electrode method,etc.In tests,appropriate independent or combined analytical technologies can be selected according to the analysis requirements of different types of nuclear fuel pellets.Furthermore,the future development of elemental content analysis for uranium-based nuclear fuel pellets is prospected.
