摘　　要：对辐照前后核燃料的物理化学性质进行分析表征是实现核动力反应堆内燃料性能可靠预测的基础之一。拉曼光谱技术可以通过分析分子振动、转动方面的信息获知物质的分子形态及物相结构变化,因其具有微量、无损、原位、高效等优点的定性定量分析能力,被广泛应用于核燃料的表征中。本文简要概述了拉曼光谱技术的基本原理,从腐蚀分析、辐照损伤分析、温度监测及高放射性样品封装等4个方面介绍了近十几年来拉曼光谱技术在核燃料分析领域的应用现状及研究进展,指出了该技术目前存在的一些局限性,并针对核燃料分析,从联用技术、数据库建立等方面对未来拉曼光谱技术的研究与应用方向进行了展望。It is one of the bases for the reliable prediction of the fuel performance in nuclear power reactors to analyze and characterize the physical and chemical properties of nuclear fuels before and after irradiation.Raman spectroscopy can obtain the information of the molecular morphology and phase structure changes of materials by the analysis of molecular vibration modes.It has been widely used in the characterization of nuclear fuels due to its excellent qualitative and quantitative analysis ability with the advantage of microscale,non-invasion,in-situ and high efficiency.In this paper,the basic principles of several Raman spectroscopy techniques are briefly summarized.The application and research progress of Raman spectroscopy on nuclear fuel analysis are summarized in the corrosion analysis,radiation damage analysis,temperature monitoring and the encapsulation technology of high radioactivity samples.The limitations of Raman spectroscopy techniques are introduced,and in view of nuclear fuel analysis,the future research and application of Raman spectroscopy are prospected from the aspects of coupled techniques and database establishment.
