This book was released on 2006 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a standardized methodology used by researchers from the Center for Accelerator Mass Spectrometry (CAMS) (Energy and Environment Directorate) and the Environmental Radiochemistry Group (Chemistry and Materials Science Directorate) at the Lawrence Livermore National Laboratory (LLNL) for the full isotopic analysis of uranium from solution. The methodology has largely been developed for use in characterizing the uranium composition of selected nuclear materials but may also be applicable to environmental studies and assessments of public, military or occupational exposures to uranium using in-vitro bioassay monitoring techniques. Uranium isotope concentrations and isotopic ratios are measured using a combination of Multi Collector Inductively Coupled Plasma Mass Spectrometry (MC ICP-MS), Accelerator Mass Spectrometry (AMS) and Alpha Spectrometry.

Download or read book Uranium Isotope Measurements by Quadrupole ICP-MS for Process Monitoring of Enrichment written by RN. Bolin and published by . This book was released on 1998 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, uranium isotopic ratio measurements in the nuclear industry have been performed using Thermal Ionization Mass Spectrometry (TIMS); primarily due to the high level of precision that can be achieved. TIMS analysis, however, requires sample purification and intricate sample loading. Quadrupole (low resolution, single detector) inductively coupled plasma -- mass spectrometry, Q-ICP-MS, overcomes these disadvantages and is a cost-effective alternative, i.e., in terms of initial capital, maintenance, and operating costs. This paper presents a simple, single standard approach for measuring uranium isotope content in various solid and liquid nuclear materials along with some comparison data of Q-ICP-MS and TIMS. Intensity ratios of 234U, 235U, 236U, and 238U to total U intensity are produced, providing the enrichment level or percent 235U. A detailed description of the instrument and data collection parameters is also provided. Optimal precision and accuracy are achieved through the use of a single standard which is closely matched to the enrichment and concentration of the samples. Depending upon the standard chosen, enrichments between depleted and 97% can be quantified. Standard deviations for the major uranium isotopes are typically within 0.02 absolute and at least an order of magnitude lower for the minor U isotope abundances.

Download or read book The Isotopic Ratio Measurement of Uranium in the Form of Hydrolyzed Uranium Hexafluoride by Inductively Coupled Plasma Multiple Collector Mass Spectrometry written by T. Hodgson and published by . This book was released on 1995 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: An inductively coupled plasma-multiple collector-mass spectrometer (ICP-MC-MS) has been used to measure the isotopic composition of uranium in three solutions of uranium hexafluoride. The 235U: 238U ratio of each sample solution ranged from approximately 0.007 to 0.03 to 1.0. The measurements are linear over this range and the precision and accuracy are comparable, if not superior, to that obtained by thermal ionization mass spectrometry (TIMS). However, acceptable isotopic ratio measurement of uranium hexafluoride solutions is not possible by TIMS because the presence of fluoride ions severely limits analytical precision. Hence, the fluoride must be removed prior to analysis. This necessitates a chemical purification stage which adds both time and expense to the measurement process. This study reports direct, high precision, accurate uranium isotope ratio measurements on solutions of uranium hexafluoride. The instrumental time required for the analysis of 15 uranium samples with the ICP-MC-MS totals 135 min. This compares with an estimated time requirement of 600 min by TIMS and a time of 900 min by UF6 gas mass spectrometry.

Download or read book Quantifying Uranium Isotope Ratios Using Resonance Ionization Mass Spectrometry written by Brett Hallen Isselhardt and published by . This book was released on 2011 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resonance Ionization Mass Spectrometry (RIMS) has been developed as a method to measure relative uranium isotope abundances. In this approach, RIMS is used as an element-selective ionization process to provide a distinction between uranium atoms and potential isobars without the aid of chemical purification and separation. We explore the laser parameters critical to the ionization process and their effects on the measured isotope ratio. Specifically, the use of broad bandwidth lasers with automated feedback control of wavelength was applied to the measurement of 235U/238U ratios to decrease laser-induced isotopic fractionation. By broadening the bandwidth of the first laser in a 3-color, 3-photon ionization process from a bandwidth of 1.8 GHz to about 10 GHz, the variation in sequential relative isotope abundance measurements decreased from>10% to less than 0.5%. This procedure was demonstrated for the direct interrogation of uranium oxide targets with essentially no sample preparation. A rate equation model for predicting the relative ionization probability has been developed to study the effect of variation in laser parameters on the measured isotope ratio. This work demonstrates that RIMS can be used for the robust measurement of uranium isotope ratios.
