Application of laser-induced plasma spectroscopy technology in nuclear fuel cycle
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 de-tection of the key elements to meet the needs of nuclear material accounting,monitoring of operating con-ditions 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-ele-ments.Therefore,LIPS has been widely concerned by researchers in the field of elemental analysis in nu-clear 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.
