[3E04] Development of Quick and Remote Analysis for Severe Accident Reactor
(4)Application of laser-induced breakdown spectroscopy to zirconium in aqueous solution
Keywords:LIBS, Solution, Zirconium, Decommissioning
Despite the wide application of LIBS to elemental analysis of gas and solid samples, it is difficult to use this method with liquid samples because splashes and ripples that form on the liquid prevent efficient detection of plasma emission in the ablation. However, LIBS using liquid jets would be the most cost-effective technique that is suitable for remote on-line analysis.
Zirconium (issued from zircaloy or fuel cladding) is among the major elements of the debris material. In this context, the present study focuses on this element determination in aqueous solutions.
