“…Direct detection of uranium in aerosol particles using LIBS was investigated in a laboratory environment. 710 Using a pulsed CO 2 laser for plasma generation, uranium atomic emission was successfully detected using ion lines at 409.0 and 411.6 nm for both aerosol particles and droplets, although no analytical figures of merit are reported. Femtosecond LIBS was used to assess the feasibility of diagnosing and profiling silver transport through the silicon carbide layer of fuel particles for the Pebble Bed Modular Reactor.…”

The first part of this two-part review focused on the fundamental and diagnostics aspects of laser-induced plasmas, only touching briefly upon concepts such as sensitivity and detection limits and largely omitting any discussion of the vast panorama of the practical applications of the technique. Clearly a true LIBS community has emerged, which promises to quicken the pace of LIBS developments, applications, and implementations. With this second part, a more applied flavor is taken, and its intended goal is summarizing the current state-of-the-art of analytical LIBS, providing a contemporary snapshot of LIBS applications, and highlighting new directions in laser-induced breakdown spectroscopy, such as novel approaches, instrumental developments, and advanced use of chemometric tools. More specifically, we discuss instrumental and analytical approaches (e.g., double- and multi-pulse LIBS to improve the sensitivity), calibration-free approaches, hyphenated approaches in which techniques such as Raman and fluorescence are coupled with LIBS to increase sensitivity and information power, resonantly enhanced LIBS approaches, signal processing and optimization (e.g., signal-to-noise analysis), and finally applications. An attempt is made to provide an updated view of the role played by LIBS in the various fields, with emphasis on applications considered to be unique. We finally try to assess where LIBS is going as an analytical field, where in our opinion it should go, and what should still be done for consolidating the technique as a mature method of chemical analysis.

“…After the Fukushima nuclear accident, some Japanese teams developed instruments of LIBS for detecting nuclear debris in soil and waste [10] . Although Penin et al described a detection of uranium in aerosol emissions of the nuclear reprocessing plants with two spectral lines of UO2F2 particles and solution drops [11] , there are still few works concern on CEM of aerosol containing uranium particles by using laser-induced breakdown spectroscopy. To investigate the potential of LIBS for direct CEM of uranium aerosol, we carry out a simulative experiment with the aerosol containing uranium dioxide particles generated by laser ablation.…”

Laser-induced breakdown spectroscopy (LIBS) is a promising technology for nuclear safeguard because of the advantages of rapid analysis, in situ and real-time detection. The potential application of LIBS is simulatively investigated for continuous uranium emission monitoring during the nuclear accident. The aerosol containing UOx is generated with laser ablation to simulate the uranium emission in laboratory. The laser induced plasma emission in the aerosol has been continuously analyzed with a spectroscopy. The characteristic spectral lines of uranium have been clearly identified. The intensity variation of uranium spectral lines agrees well with UOx particles emission and sedimentation process in aerosol.The potential of LIBS is demonstrated for emergency and continuous emission monitor in nuclear accidents.

“…Study of radiation effects is also required for future applications of the developed system such as sample analysis of the retrieved fuel debris out of the reactor site, a handy survey of the contaminated field, and monitoring of decontamination process, as well as the remote fuel debris inspection. Although LIBS has been applied in the field of nuclear science [23][24][25] and analysis of nuclear materials [26][27][28][29][30][31], its operation under high radiation dose rate as conducted in this study is rare.…”
