Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the Los Alamos ATW (Accelerator Transmutation of nuclear Waste) project is to utilize a high-energy (800--1600 MeV), high current (25--60mA) proton beam to generate a large neutron flux for the transmutation of nuclear wastes. Our theoretical modeling efforts have been directed toward designing a device that will transmute the 2000 kg of Tc and I in the Hanford waste depository along with significant quantities of actinides. Previous system studies have indicated the feasibility of such a device. However, it required thirty years to transmute 2000 kg of Tc and 400 kg of Np. In the present work, we have expanded on the previous study and focused on a device which will significantly reduce the time required for the transmutation of the fission products. 3 refs., 1 tab.

Book excerpt: The Los Alamos Accelerator Transmutation of Nuclear Waste (ATW) concept consists of four principal systems: accelerator, neutron spallation target, blanket, and chemical separator. The device is designed to transmute actinides and fission products carried in heavy water slurries or aqueous solutions. The design goals of the device are to transmute the actinide and fission product waste from at least two 1000 MW{sub e} LWR{sub s}, and to produce enough electricity to power the accelerator with some excess to sell to local power utilities. This means our goal is to transmute 80 kg of technetium and iodine, and 600 kg of actinide per year. This device is the latest in a series of ATW systems that have been studied by Los Alamos National Laboratory. Each device has been the object of many radiation physics calculations in order to arrive at some local optimum in terms of transmutation rates and achievable power production. Our basic calculational tool is the one-dimensional transport code ONEDANT. It is important to know, however, how close our results are to those obtainable from a real device. This requires that two- and three-dimensional calculations be made in order to obtain a calculational benchmark. For the two- and three-dimensional calculations we use the codes TWODANT and MCNP, respectively. This paper presents the results of one set of comparisons for the ATW device discussed above.

Available in PDF, EPUB and Kindle. Book excerpt: Disposal of radioactive waste from nuclear weapons production and power generation has caused public outcry and political consternation. Nuclear Wastes presents a critical review of some waste management and disposal alternatives to the current national policy of direct disposal of light water reactor spent fuel. The book offers clearcut conclusions for what the nation should do today and what solutions should be explored for tomorrow. The committee examines the currently used "once-through" fuel cycle versus different alternatives of separations and transmutation technology systems, by which hazardous radionuclides are converted to nuclides that are either stable or radioactive with short half-lives. The volume provides detailed findings and conclusions about the status and feasibility of plutonium extraction and more advanced separations technologies, as well as three principal transmutation concepts for commercial reactor spent fuel. The book discusses nuclear proliferation; the U.S. nuclear regulatory structure; issues of health, safety and transportation; the proposed sale of electrical energy as a means of paying for the transmutation system; and other key issues.

Download or read book Inertial Electrostatic Confinement IEC Fusion written by George H. Miley and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment proposed for demonstrating breakeven conditions for using p-B11 in a hydrogen plasma simulation. This book also: Offers an in-depth look, from introductory basics to experimental simulation, of Inertial Electrostatic Confinement, an emerging method for generating fusion power Discusses how the Inertial Electrostatic Confinement method can be applied to other applications besides fusion through theoretical experiments in the text Details the study of the physics of Inertial Electrostatic Confinement in small-volume plasmas and suggests that their rapid reproduction could lead to the creation of a large-scale power-producing device Perfect for researchers and students working with nuclear fusion, Inertial Electrostatic Confinement (IEC) Fusion: Fundamentals and Applications also offers the current experimental status of IEC research, details supporting theories in the field and introduces other potential applications that stem from IEC.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic and comprehensive introduction to the neutronics of advanced nuclear systems, covering all key aspects, from the fundamental theories and methodologies to a wide range of advanced nuclear system designs and experiments. It is the first-ever book focusing on the neutronics of advanced nuclear systems in the world. Compared with traditional nuclear systems, advanced nuclear systems are characterized by more complex geometry and nuclear physics, and pose new challenges in terms of neutronics. Based on the achievements and experiences of the author and his team over the past few decades, the book focuses on the neutronics characteristics of advanced nuclear systems and introduces novel neutron transport methodologies for complex systems, high-fidelity calculation software for nuclear design and safety evaluation, and high-intensity neutron source and technologies for neutronics experiments. At the same time, it describes the development of various neutronics designs for advanced nuclear systems, including neutronics design for ITER, CLEAR and FDS series reactors. The book not only summarizes the progress and achievements of the author’s research work, but also highlights the latest advances and investigates the forefront of the field and the road ahead.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest challenges for nuclear energy is how to properly manage the highly radioactive waste generated during irradiation in nuclear reactors. Accelerator Driven Systems (ADSs) may offer new prospects and advantages for the transmutation of such high level nuclear waste. ADS or accelerator driven transmutation of waste (ATW) consists of a high power proton accelerator, a heavy metal spallation target that produces neutrons when bombarded by the high power beam, and a sub-critical core that is neutronically coupled to the spallation target. This publication provides a comprehensive state of the art of the ADS technology by representing the different ADS concepts proposed worldwide in the last 15 years, as well as the related R&D activities and demonstration initiatives carried out at national international level.
