Real-Time Quantification of Hydrogen and Deuterium Using Laser-Induced Breakdown Spectroscopy (LIBS) in the Off-Gas of an Engineering-Scale Pumped Molten Salt Loop
Laser-induced breakdown spectroscopy (LIBS) is being considered for elemental analysis of radionuclides transported into the off-gas system of molten salt reactors. A mobile LIBS system was calibrated for gas-phase measurements of hydrogen (i.e., protium, denoted here as H) and deuterium (D) in argon (Ar). The system was then used to quantify the concentrations of H and D…
