Book Description
Analytical formulations that describe the time dependence of neutron populations in nuclear materials contain delayed-neutron dependent terms. These terms are important because the delayed neutrons, even though their yields in fission are small, permit control of the fission chain reaction process. Analytical applications that use delayed neutrons range from simple problems that can be solved with the point reactor kinetics equations to complex problems that can only be solved with large codes that couple fluid calculations with the neutron dynamics. Reactor safety codes, such as SIMMER, model transients of the entire reactor core using coupled space-time neutronics and comprehensive thermal-fluid dynamics. Nondestructive delayed-neutron assay instruments are designed and modeled using a three-dimensional continuous-energy Monte Carlo code. Calculations on high-burnup spent fuels and other materials that contain a mix of uranium and plutonium isotopes require accurate and complete information on the delayed-neutron periods, yields, and energy spectra. A continuing need exists for delayed-neutron parameters for all the fissioning isotopes.

Book Description
Studies in Analytical Chemistry, 3: Nondestructive Activation Analysis focuses on the reactions, principles, methodologies, and approaches involved in nondestructive activation analysis. The selection first offers information on irradiation, measurement and techniques, and manual and computerized data processing in activation analysis. Discussions focus on result computation with Nal(Tl) and Ge(Li) data, analysis of gamma-ray spectra, X-ray, spectrometry, neutron counting in activation analysis, neutron sources, and measurement of very short-lived nuclides. The book then examines applications, including biomedical sciences, geo- and cosmochemistry, applications of trace element analysis to studies of the atmospheric environment, and high purity materials, standards, and reference materials. The text discusses the applications of nondestructive activation analysis to archaeology, industry, and forensics. The selection is a vital reference for researchers wanting to explore nondestructive activation analysis.

Book Description
This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.
