【摘要】 后处理工艺过程控制分析技术是乏燃料后处理技术的重要组成部分,是一项独特和专门的技术领域。锕系元素的5-f电子轨道构型,具有特殊的光谱,使光谱分析技术在后处理工艺控制及研究中得到广泛应用。光谱分析与光纤相结合形成光纤光谱分析技术,再根据后处理工艺的特点加以改进,满足后处理工艺的分析要求,对于后处理工艺过程控制中相关元素的价态及浓度分析具有重要意义。乏燃料后处理相关技术属于敏感技术,本文根据有限的文献和资料,对国内外近年来核燃料后处理过程的光纤光谱技术应用研究进展进行了综述。更多还原

【Abstract】 Spent fuel reprocessing process control analysis technology is an important part of spent fuel reprocessing technology,is a specialized technical field.Actinides are particularly suited for measurement via spectrophotometric techniques as their f-orbital interactions provide a unique spectrum for almost every actinide in various oxidation states.For valance and concentration analysis of actinides,spectroscopy is play an important role.Spectral analysis combined with optical fiber forming fiber spectroscopy analysis technology,according to the characteristics of reprocessing technology improved,satisfy the requirement of reprocessing process analysis.Spent fuel reprocessing technology belongs to sensitive technology,based on the limited literature and data,this paper summarizes the research progress of the application of optical spectra in nuclear fuel reprocessing process in recent years.更多还原
