Abstract

The accurate measurement of radionuclides through advanced analytical techniques is essential for ensuring the safety and efficiency of nuclear fuel reprocessing. This study presents the use of different Raman spectrometers to analyze the fluorescence of lanthanide elements such as Neodymium and Europium. By employing Raman spectrometers with different excitation wavelengths (532 nm and 785 nm), the detection and quantification of the fluorescence peaks of Nd³⁺ and Eu³⁺ were achieved in both organic and aqueous phases. This method provides a fast and effective way to monitor the behavior of these elements in various reprocessing conditions, simulating the co-extraction step of an extraction process involving TODGA under both normal operation conditions and simulated maloperation conditions. The findings demonstrate the potential of Raman spectrometers as a powerful tool for the non-invasive and real-time analysis of key components in nuclear fuel management.

先进核后处理分析用拉曼光谱仪测量放射性核素

通过先进的分析技术对放射性核素进行精确测量，对于确保核燃料后处理的安全和效率至关重要。本研究介绍了使用不同的拉曼光谱仪来分析镧系元素（如钕和铕）的荧光。采用不同激发波长（532 nm和785 nm）的拉曼光谱仪，实现了有机相和水相中Nd3+和Eu3+荧光峰的检测和定量。该方法提供了一种快速有效的方法来监测这些元素在各种后处理条件下的行为，模拟了在正常运行条件和模拟误操作条件下涉及TODGA的萃取过程的共萃取步骤。这些发现证明了拉曼光谱仪作为一种强大的工具的潜力，可以对核燃料管理中的关键成分进行非侵入性和实时分析。
