Book Description
This work integrates analysis techniques common to destructive nuclear forensics and non-destructive safeguards in the radio-nuclear analysis of plutonium. This work accomplishes this task by applying deconvolution methodologies typical in alpha spectrometry to the analysis of LaBr3:Ce spectra. It further integrates and applies uncertainty methodology common to destructive chemistry laboratories to the nondestructive analysis of plutonium. In pursuit of this aim, an alpha spectrometry deconvolution algorithm is developed capable of determining the 241Am/Pu mass fraction in plutonium with about a 1% uncertainty with a 95% coverage factor. Results agree very well with published alpha spectrometry and mass spectrometry mass ratios. Model ages calculated from the 241Pu/241Am chronometer also agree very well with the historical separation dates for reference materials that have been well purified chemically. A sister program is developed capable of determining plutonium mass ratios in spectra obtained with LaBr3:Ce scintillation detectors. This method is capable of determining the mass ratios with total measurement uncertainties of about 16%, 26%, 10%, and 4% (k = 2) for the mass ratios (relative to 239Pu) for 238Pu, 240Pu, 241Pu, and 241Am, respectively for 15 minute duration spectra of reactor grade plutonium obtained at Los Alamos National Laboratory. Results for weapons-grade plutonium are somewhat worse with uncertainties for the mass ratios 240Pu, 241Pu, and 24Am of about 30%, 80% and 10% (k = 2), respectively. The primary issue with this work is a somewhat higher systematic uncertainty for 240Pu content in reactor grade plutonium for spectra taken by the International Atomic Energy Agency (IAEA). Further, a bottom up uncertainty methodology for plutonium non-destructive [gamma]-ray analysis is developed. Unlike the two primary plutonium analysis codes Fixed Energy Response Function Analysis with Multiple Efficiencies (FRAM) and Multi-Group Analysis (MGA), this methodology propagates uncertainty from many different contributors according to the Joint Committee for Guides in Metrology (JCGM) Guide to the Expression of Uncertainty in Measurement (GUM) supplement 1. It is demonstrated this method yields very high fidelity uncertainties for 238Pu, 239Pu, and 240Pu content in unshielded coaxial spectra in high statistics spectra when compared to a top down analysis. Finally, this work develops a method to determine much improved plutonium photon emission intensities markedly different from the prior art. It is planned to incorporate these improved emission intensity values and derived uncertainties into the GUM uncertainty model for FRAM.

ISBN: 9789201189103
Category : Environmental sampling
Languages : en
Pages : 146
Book Description
The 1990s saw significant developments in the global non-proliferation landscape, resulting in a new period of safeguards development. The current publication, which is the second revision and update of IAEA/NVS/1, is intended to give a full and balanced description of the safeguards techniques and equipment used for nuclear material accountancy, containment and surveillance measures, environmental sampling, and data security. New features include a section on new and novel technologies. As new verification measures continue to be developed, the material in this book will be reviewed periodically and updated versions issued.
Handbook on Battery Energy Storage System
Author: Asian Development BankPublisher: Asian Development Bank
ISBN: 9292614711
Category : Technology & Engineering
Languages : en
Pages : 123
Book Description
This handbook serves as a guide to deploying battery energy storage technologies, specifically for distributed energy resources and flexibility resources. Battery energy storage technology is the most promising, rapidly developed technology as it provides higher efficiency and ease of control. With energy transition through decarbonization and decentralization, energy storage plays a significant role to enhance grid efficiency by alleviating volatility from demand and supply. Energy storage also contributes to the grid integration of renewable energy and promotion of microgrid.

Book Description
The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.
