Book High Precision Isotopic Analyses of Uranium and Plutonium by Total Sample Volatilization and Signal Integration

Download or read book High Precision Isotopic Analyses of Uranium and Plutonium by Total Sample Volatilization and Signal Integration written by and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques have been developed which permit rapid, high-precision analyses of uranium and plutonium by multiple-filament thermal ionization mass spectrometry utilizing a commercial multicollector instrument. The salient feature of the method is volatilization of the entire sample while simultaneously integrating the signal from each isotope, thus virtually eliminating the effects of isotope fractionation in the evaporation process. The method permits the analysis of samples much smaller than required for conventional techniques using Faraday collectors and is expected to have application in the analysis of many elements in addition to uranium and plutonium.

Book Simplified Method for the Preparation of Micro Samples for the Simultaneous Isotopic Analysis of Uranium and Plutonium

Download or read book Simplified Method for the Preparation of Micro Samples for the Simultaneous Isotopic Analysis of Uranium and Plutonium written by and published by . This book was released on 1974 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A basic anion resin is employed to selectively adsorb plutonium and uranium from 8 M HNO3 solutions containing dissolved spent reactor fuels. After a few beads of the resin are equilibrated with the solution, a single bead is used for establishing the isotopic composition of plutonium and uranium. The resin bead separation essentially removes all possible isobaric interference from such elements as americium and curium and at the same time eliminates most fission product contamination in the mass spectrometer. Small aliquots of dissolver solution that contain 10−6g of U and 10−8 g of Pu are adequate for preparing about ten resin beads. By employing a single-focusing, tandem-magnet-type mass spectrometer, equipped with pulse counting for ion detection, simultaneous plutonium and uranium assays are obtained. The quantity of each element per bead may be as low as 10−9 to 10−1°g. The technique of isotope dilution can be coupled with the ion exchange bead separation and used effectively for measuring the total quantity of U and Pu. The technique possesses advantages such as: reduced radiation hazards from the infinitely smaller samples, thus less shielding and transport cost for sample handling; greatly simplified chemical preparations that eliminate fission products and actinide isobaric interferences; and the minor isotopes are more precisely established.
