X-ray fluorescence analysis of spent reactor fuel solutions
The present work examines the possibility of laboratory analytic control by means of a crystal-free x-ray fluorescence analysis (XRFA) installation specifically designed for this purpose with a prior selection of fluorescent emissions by energy. Monitoring by fluorescent emissions from selenium positioned in the installation along with a metering cuvette allows the exclusion of errors associated with the instability of the x-ray tube beam and the effects of the superpositioning of impulses and of dead time. Tests were made on the possibility of using hard standards, consisting of pellets of uranium-aluminum alloy in a fluoroplastic casing. Some characteristics are shown of the crystal-free x-ray fluorescent method of determining uranium concentration in the technological products from reprocessing spent fuel from a water-moderated, water-cooled reactor. The determination of the uranium content in diluted incoming solutions in the reprocessing of spent fuel from such a reactor was also tested by comparison with the results of the method of isotopic dilution concluded using mass-spectrometry.
