Abstract
A versatile, nondestructive system for the measurement of uranium and plutonium concentrations in process solutions from the reprocessing of spent nuclear fuels has been developed at KfK and successfully demonstrated in a hot cell environment at the European Institute for Transuranium Elements, Karlsruhe. The NDA system incorporates the proven X-ray techniques of K-edge densitometry ar.c. fluorescence analysis of K series X-rays. The feasibility of direct nondestructive uranium and plutonium assay in reprocessing input solutions using this system is demonstrated from measurements or: actual dissolver solutions. The performance of the system is evaluated by comparing the results with these of parallel analyses performed by the conventional isotope dilution mass-spectrometry technique.
