摘　　要：核燃料的安全、高效循环是保障核能可持续发展的基础。在核燃料循环过程中,为满足核材料衡算、核设施运行工况监控和安全保障需求,需要对涉核材料的关键成分进行快速、在线、非接触的探测分析。激光诱导等离子体光谱(LIPS)技术作为一项新兴的原子发射光谱分析技术,具有操作简单、检测速度快等优势,可实现在线-非接触检测和多元素同步检测,得到了核燃料循环过程元素分析领域研究人员的广泛关注。本文从铀矿石探测、核燃料加工、放射性污染物处理等3个方面,对LIPS技术在核燃料循环全过程中的应用进行介绍,并对其发展前景进行展望。The safe and efficient cycle of nuclear fuel is the foundation for the sustainable development of nuclear energy.In the nuclear fuel cycle process,it is necessary to conduct fast,online and non-contact detection of the key elements to meet the needs of nuclear material accounting,monitoring of operating conditions of nuclear facilities and safety assurance.Laser-induced plasma spectroscopy(LIPS)is an emerging atomic spectrum analysis technology with the advantages of simple operation and fast detection speed.It can realize the on-line and non-contact detection as well as the simultaneous determination of multi-elements.Therefore,LIPS has been widely concerned by researchers in the field of elemental analysis in nuclear fuel cycle.In this paper,the application of LIPS in the nuclear fuel cycle was reviewed focusing on three aspects:uranium ore detection,nuclear fuel processing,and radioactive contaminant treatment.The application of LIPS technology in whole process of nuclear fuel cycle was introduced,and its development prospect was discussed.
