Currently, the research I perform within the UNLV radiochemistry research program involves solvent extraction processes that are used for the recovery of various components from dissolved spent nuclear fuel. The capability of spectroscopic methods such as time resolved laser fluorescence spectroscopy, and UV/Visible spectroscopy in monitoring nuclear materials in solvent extraction streams is being explored. On-line monitoring of the actinides ensures that proliferation concerns are mediated. Experimental design demands a thorough appreciation of the extraction process associated with each feed stream, including distribution constants, potential reactions, and effects of process conditions (i.e. metal concentrations, pH, ionic strength, temperature). Time resolved laser fluorescence spectroscopy and UV/Visible spectroscopy is used to determine nuclear materials (uranium, plutonium, technetium, etc.) content for each stream as process conditions are varied. Limits of linearity are determined. The error associated with method is carefully calculated and reported. Molar absorptivity constants are required for each variation of parameters. Liquid scintillation counting is employed as a method for appraisal of metal concentration and subsequently used to construct the calibration plots. This requires that the prevailing conditions of the standard samples carefully match those of the extracted streams, since the liquid scintillation cocktail is especially sensitive to the matrix of each sample. Titration may be used to elucidate the pH or other electrolyte concentrations in poorly understood extracted streams. In addition, ICP-AES is often used to provide another means of clarifying sample content.
