Research progress on application of laser-induced breakdown spectroscopy in spent fuel reprocessing
Laser-induced breakdown spectroscopy(LIBS)is a multi-element simultaneous measurement tech-nology,and it has the characteristics of simple sample preparation,fast detection speed,high environmen-tal tolerance,remote measurement and online analysis ability.LIBS has great advantages in the process control of spent fuel reprocessing and the safe operation monitoring of facilities.In recent years,there are more and more reports about the analysis of nuclear materials by LIBS.In this paper,the research pro-gress of LIBS in detection of molten salt,off-gas and gaseous uranium,high-level liquid waste and vitrifi-cation,surface contamination,alloy and their oxides were reviewed.The existing problems in quantitative analysis were summarized.The future development in the nuclear field was expected.
