Russia proposes optical laser monitoring method for spent nuclear fuel reprocessing

Recently, a research team from Sechenov University in Russia, together with the Proryv Project and the All-Russian Scientific Research Institute of Inorganic Materials (VNIINM), published latest results in the journal Applied Spectroscopy, proposing a non-contact optical method for continuous monitoring of the spent nuclear fuel reprocessing process. It is reported that in the liquid-liquid extraction process of spent nuclear fuel reprocessing, traditional laboratory analysis has problems such as long sampling time and increased risk of radioactive waste. The research team introduced Raman Spectroscopy to monitor the state of extractants such as tributyl phosphate in the organic phase, measuring a median error of about 1%; meanwhile, laser-induced breakdown spectroscopy (LIBS) was used to determine the concentration of metal elements in the aqueous phase, with an average error controlled at 4%–8%, achieving near-real-time synchronous monitoring of the two-phase streams.
