The Separation of Light Gaseous Isotopes by Mass Diffusion Columns
(8 7Rb/8 5Rb) from chloride ( 8 7 Rb/ 8 5 Rb) from nitrate 1.011 ± 0 . 0 0 7 1.014 ± 0.008 Table 2. Difference in the measured isotopic abundance of rubidium due to various chemical compounds. Given are the ratios of 87Rb/85Rb ratios obtained from the two different chemical compounds indicated in the first column. Absolute ratios and standard deviations were calculated in a corresponding manner...
متن کاملThe Separation of Light Gaseous Isotopes by Mass Diffusion Columns II
The design of mass diffusion columns operated with partition membranes, for the separation of light gaseous isotopes, is discussed. A theoretical analysis of experimental results obtained indicates that a good agreement between experimental results and theory is only obtained at low column pressures and moderate countercurrent flow rates. At fairly low countercurrent flow rates mixing effects d...
متن کاملAnalysis and Optimization of Gas- Centrifugal Separation of Uranium Isotopes by Neural Networks
Neural networks are an attractive alternative for modeling complex problems with too many difficulties to be solved by a phenomenological model. A feed-forward neural network was used to model a gas-centrifugal separation of uranium isotopes. The prediction showed good agreement with the experimental data. An optimization study was carried out. The optimal operational condition was tested by a ...
متن کاملDetermination of uranium isotopes (234U, 238U) and natural uranium (U-nat) in water samples by alpha spectrometry
Background: Due to the potential public health effects of releases of uranium to the environment, isotopic determination and measurement of this radionuclide in environmental samples is very important. Achieving this goal, monitoring programs for this radionuclide seems necessary to be applied in many countries. Materials and Methods: The uranium was separated from the water samples using anion...
متن کاملComputational Analysis of Signatures of Highly Enriched Uranium Produced by Centrifuge and Gaseous Diffusion
Different enrichment processes have been used historically to produce highly enriched uranium (HEU) for weapon purposes. The most relevant ones are the gaseous diffusion process and the gas centrifuge. The two exploit different physical principles to separate isotopes of different molecular weight. It could therefore be expected that HEU might carry an isotopic signature that is unique to the e...
