Book The Determination of Uranium and Thorium by the Use of Delayed Neutrons

Download or read book The Determination of Uranium and Thorium by the Use of Delayed Neutrons written by DM. Bibby and published by . This book was released on 1974 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analytical method developed is based on the detection of the delayed neutrons emitted by some fission products. Limitations in the irradiation facilities at present available result in a limit of detection of 5 ppm of uranium and 3000 ppm of thorium in a 50 mg sample. Two hundred determinations per day can be made, and modifications are suggested to improve this figure.

Book The Measurement of Uranium Concentrations by the Delayed Neutron Counting Technique

Download or read book The Measurement of Uranium Concentrations by the Delayed Neutron Counting Technique written by R. I. Scherpelz and published by . This book was released on 1978 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The counting of delayed neutrons emitted by fission is presented as a valuable technique for the measurement of uranium concentrations in a variety of matrices. The concentrations successfully analyzed can vary from well under one part per million to the high concentrations found in uranium ores. In a sample analysis, fission is induced in the uranium in the sample by irradiation in a thermal neutron flux, then the sample is rapidly transferred to a counting assembly capable of detecting delayed neutrons. In the system described, irradiation is performed in a TRIGA reactor, and counting is done in a paraffin-moderated assembly of BF3 gas-filled detectors. All equipment needed for the analysis and the necessary procedures are discussed. The delayed fission neutron (DFN) counting technique is compared to other methods of analysis for uranium, and the experiences of other researchers using the DFN technique are summarized. When compared to many other methods, DFN counting is relatively free of interferences. The interferences which may occur, such as high energy gammas, unknown neutron-emitting nuclides or strong neutron absorbers in the sample, are discussed. Any uncertainties associated with a DFN measurement are also analyzed. DFN counting has been used in many applications, such as the measurement of uranium in geological samples, phosphate products and seawater adsorbers. It can also be used for the measurement of thorium in many samples. These applications are presented, and the results of many different analyses are listed. Experience gained at Oregon State University is examined in detail, and several improvements are suggested.
