摘      要：The amounts of nuclear materials in the Li Cl-KCl salt in pyroprocessing have to be analyzed to prevent the diversion of the nuclear *** alternative method to the chemical analysis has been pursued,and laser-induced breakdown spectroscopy(LIBS)is one *** the present work,an in situ and quantitative analysis method of electro-recovery(ER)salt was proposed and demonstrated by using LIBS combined with dipstick *** types of simulated salt samples were prepared:ER salt sample and salt obtained from the dipstick sampling,and pulsed neodymium-doped yttrium aluminum garnet(Nd:YAG)laser with a wavelength of 532 nm was focused on the salt to generate *** plasma emission was measured by using an Echelle spectrometer with a resolution of 0.01 nm in conjunction with an Intensified Charge-Coupled Detector *** U and other rare earth peaks in the spectra were *** best Limit of Detection and Root Mean Square Error of Calibration of U were 38 ppm and 0.0203 wt%,*** work shows that the U in the pyroprocessing ER salt can be monitored with LIBS.
