This book was released on 1998 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: This summary describes measurements performed on four annular uranium metal castings of different enrichments to investigate the use of 252Cf-source-driven noise analysis measurements as a means to quantify the amount of special nuclear material (SNM) in the casting. Previous measurements and calculational studies have shown that many of the signatures obtained from the source-driven measurement are sensitive to fissile mass. Measurements were performed to assess the applicability of this method to standard annular uranium metal castings at the Oak Ridge Y-12 plant under verification by the International Atomic Energy Agency (IAEA) using the Nuclear Weapons Identification System (NWIS) processor. The sensitivity of the measured parameters to fissile mass was investigated using four castings each with a different enrichment. Preliminary results are presented that demonstrate the sensitivity of the measured parameter to fissile mass. However, these preliminary results do not represent an optimized measurement configuration but are intended to demonstrate possible applications of this method.

Available in PDF, EPUB and Kindle. Book excerpt: Subcritical source-driven noise measurements are simultaneous Rossi-[alpha] and randomly pulsed neutron measurements that provide measured quantities that can be related to the subcritical neutron multiplication factor. In fact, subcritical source-driven noise measurements should be performed in lieu of Rossi-[alpha] measurements because of the additional information that is obtained from noise measurements such as the spectral ratio and the coherence functions. The basic understanding of source-driven noise analysis measurements can be developed from a point reactor kinetics model to demonstrate how the measured quantities relate to the subcritical neutron multiplication factor. More elaborate models can also be developed using a generalized stochastic model. These measurements can be simulated using Monte Carlo codes to determine the subcritical neutron multiplication factor or to determine the sensitivity of calculations to nuclear cross section data. The interpretation of the measurement using a Monte Carlo method is based on a perturbation model for the relationship between the spectral ratio and the subcritical neutron multiplication factor. The subcritical source-driven noise measurement has advantages over other subcritical measurement methods in that reference measurements at delayed critical are not required for interpreting the measurements. Therefore, benchmark or in-situ subcritical measurements can be performed outside a critical experiment facility. Furthermore, a certain ratio of frequency spectra has been shown to be independent of detection efficiency thereby making the measurement more robust and unaffected by drifts or changes in instrumentation during the measurement. Criteria have been defined for application of this measurement method for benchmarks and in-situ subcritical measurements. An extension of the source-driven subcritical noise measurement has also been discussed that eliminates the few technical challenges for in-situ applications.

Download or read book Practical Gamma Ray Spectrometry written by Gordon Gilmore and published by Wiley. This book was released on 1995-05-30 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray spectrometry is a key technique in the study of the decay of radioactive materials. Used by scientists from a wide range of disciplines, problems can be encountered by the inexperienced user because there is a deceptive simplicity in gamma-ray measurements which can hide significant pitfalls. To resolve this situation, the authors of Practical Gamma-Ray Spectrometry have drawn on many years of teaching experience to produce this uniquely practical volume, giving comprehensive coverage of the whole gamma-ray detection and spectrum analysis processes. Discussions of the origin of gamma-rays and the issue of quality assurance in gamma-ray spectrometry are also included. Practical Gamma-Ray Spectrometry is written with the user in mind and has the following benefits: * Mathematics are kept to a minimum throughout. * No previous knowledge of nuclear matters or instrumentation is assumed. * Detectors and their associated electronic systems are discussed. * Fault-finding guide ensures that any problems can be sorted out with the minimum of fuss. Practical Gamma-Ray Spectrometry will enable all those involved with radioactivity measurements to get the most from their equipment. It will also be of great value to teachers and students in departments where radioactivity is studied, such as physics, chemistry, environmental biology, archaeometry and radiochemistry.

Book excerpt: This book describes the Proceedings of the International Conference on Nuclear Data for Science and Technology held at Jillich in May 1991. The conference was in a series of application oriented nuclear data conferences organized in the past under the auspices of the Nuclear Energy Agency-Nuclear Data Committee (NEANDC) and with the support of the Nuclear Energy Agency-Committee on Reactor Physics (NEACRP). It was the fIrst international conference on nuclear data held in Germany, with the scientific responsibility entrusted to the Institute of Nuclear Chemistry of the Research Centre Jillich. The scientific programme was established by the International Programme Committee in consultation with the International Advisers, and the NEA and IAEA cooperated in the organization. A total of 328 persons from 37 countries and fIve international organizations participated. The scope of these Proceedings extends to a wide range of interdisciplinary topics dealing with measu rement, calculation, evaluation and application of nuclear data, with a major emphasis on numerical data. Both energy and non-energy related applications are considered and due attention is given to some fundamental aspects relevant to the understanding of nuclear data.

This book was released on 2010-02-23 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prompt gamma activation analysis (PGAA) is a unique, non-destructive nuclear analytical method with multi-element capabilities. It is most effective if intense neutron beams (especially cold beams) of nuclear reactors are used to induce the prompt gamma radiation. Based largely on the authors' pioneering research in cold neutron PGAA, the handbook describes the methodology in self-contained manner and reviews recent applications. The library of prompt gamma ray data and spectra for all natural elements is a unique aid to the practitioner. The level is understandable by a broad audience, which facilitates teaching and training. The Handbook of Prompt Gamma Activation Analysis is a comprehensive handbook written for those practising the method, wanting to implement it at a reactor facility, or just looking for a powerful non-destructive method of element analysis. The book is also useful for nuclear physics, chemistry and engineering scientists, scholars and graduate students interested in neutron-induced gamma ray spectroscopy and nuclear analytical methods.
