This book was released on 2024-08-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book describes the nondestructive assay techniques that are used for the measurement of nuclear material (primarily uranium and plutonium) for nuclear material accountancy purposes. It is a substantial revision to the so-called PANDA manual that has been a standard reference since its publication in 1991. The book covers the origin and interactions of gamma rays and neutrons as they affect nuclear measurements and also describes the theory and practice of calorimetry. The book gives a description of many instruments based on these techniques that are applied in the field. Although the basic physics has not changed since PANDA was first published, the last thirty years have seen many advances in analysis methods, instrumentation, and applications. The basic descriptions of the origin and interactions of radiation have been updated and include newer references. There have been extensive revisions of the description of gamma detection methods, attenuation correction procedures, and analysis methods, including for the measurement of uranium enrichment and the determination of plutonium isotopic composition. Extensive revisions and additions have also been made to the description of neutron detectors and to the explanation of neutron coincidence techniques. The chapter on neutron multiplicity techniques is a new addition to this edition. The applications of gamma and neutron techniques have been completely overhauled to remove obsolete systems and to include many current applications. The values of, and references to, nuclear data have been updated. This updated edition is an essential reference for academic researchers and practitioners in the field. This is an open access book.

Available in PDF, EPUB and Kindle. Book excerpt: A high-quality materials accounting system and effective international inspections in uranium fuel-fabrication facilities depend heavily upon accurate nondestructive assay measurements of the facilitys̀ nuclear materials. While item accounting can monitor a large portion of the facility inventory (fuel rods, assemblies, storage items), the contents of all such items and mass values for all bulk materials must be based on quantitative measurements. Weight measurements, combined with destructive analysis of process samples, can provide highly accurate quantitative information on well-characterized and uniform product materials. However, to cover the full range of process materials and to provide timely accountancy data on hard-to-measure items and rapid verification of previous measurements, radiation-based nondestructive assay (NDA) techniques play an important role. NDA for uranium fuel fabrication facilities relies on passive gamma spectroscopy for enrichment and U isotope mass values of medium-to-low-density samples and holdup deposits; it relies on active neutron techniques for U-235 mass values of high-density and heterogeneous samples. This paper will describe the basic radiation-based nondestructive assay techniques used to perform these measurements. The authors will also discuss the NDA measurement applications for international inspections of European fuel-fabrication facilities.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive assay (NDA) of special nuclear material (SNM) is used in nonproliferation applications, including identification of SNM at border crossings, and quantifying SNM at safeguarded facilities. No assay method is complete without "error bars," which provide one widely used way to express confidence in assay results. NDA specialists typically partition total uncertainty into "random" and "systematic" components so that, for example, an error bar can be developed for the SNM mass estimate in one item or for the total SNM mass estimate in multiple items. Uncertainty quantification (UQ) for NDA has always been important, but greater rigor is needed and achievable using modern statistical methods. To this end, we describe the extent to which the guideline for expressing uncertainty in measurements (GUM) can be used for NDA. Also, we describe possible extensions to the GUM by illustrating UQ challenges in NDA that it does not address, including calibration with errors in predictors, model error, and item-specific biases. Here, a case study is presented using gamma spectra and applying the enrichment meter principle to estimate the235U mass in an item. The case study illustrates how to update the ASTM international standard test method for application of the enrichment meter principle using gamma spectra.

This book was released on 1970 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A RESEARCH AND DEVELOPMENT PROGRAM IS BEING CARRIED OUT AT GULF GENERAL ATOMIC TO DEVELOP QUANTITATIVE MEASUREMENT TECHNIQUES FOR SPECIAL NUCLEAR MATERIAL WHICH IS DIFFICULT TO MEASURE BY CONVENTIONAL MEANS. THE APPROACH TAKEN IS TO IRRADIATE THE ITEM TO BE MEASURED WITH A PENETRATING RADIATION BEAM FROM A LINAC. THE BEAM PRODUCES CHARACTERISTIC NUCLEAR REACTIONS SUCH AS THE PHOTOFISSION AND PHOTONEUTRON REACTIONS AND THE RESULTING REACTION RADIATIONS ARE MEASURED WITH DETECTOR SYSTEMS. THE REACTION RADIATIONS INCLUDE PROMPT NEUTRONS, DELAYED NEUTRONS, AND GAMMA RAYS FROM FISSION PRODUCTS. FROM THE INTENSITIES OF THE REACTION RADIATIONS, THE ISOTROPIC CONTENT AND THE QUANTITY OF NUCLEAR MATERIALS MAY BE DETERMINED. THE REACTION YIELDS FROM A NUMBER OF NUCLEAR MATERIALS HAVE BEEN MEASURED. THESE INCLUDE THE BREMSSTRAHLUNG INDUCED PHOTONEUTRON YIELD FROM 5 TO 10 MEV IN (235)U, (238)U AND (239)PU. THE PHOTOFISSION PRODUCED TIME DISTRIBUTION OF DELAYED NEUTRONS AND THE SPECTRA OF POST-BETA DECAY GAMMA RAYS HAVE ALSO BEEN MEASURED FOR THE SAME ISOTOPES. QUANTITATIVE ISOTROPIC ASSAYS ON METAL, OXIDE, AND WATER CONTAINING SAMPLES WITH PRECISIONS NEAR 1% HAVE DEMONSTRATED THE VALIDITY OF THE TECHNIQUE. A SMALL TRANSPORTABLE ELECTRON ACCELERATOR HAS BEEN DESIGNED AND IS UNDER CONSTRUCTION AT GULF GENERAL ATOMIC. A ROADABLE TRAILER IS BEING MODIFIED TO CONTAIN THE ACCELERATOR, A BARREL SCANNER, AND DETECTION AND DATA ACCUMULATION ELECTRONICS. THE TRAILER WILL BE USED AT VARIOUS SITES THROUGHOUT THE COUNTRY TO DEMONSTRATE NONDESTRUCTIVE ASSAY TECHNIQUES. SUCH DEMONSTRATIONS ARE EXPECTED TO STIMULATE THE APPLICATION OF NONDESTRUCTIVE ASSAY TECHNIQUES THROUGHOUT THE NUCLEAR FUEL INDUSTRY.
