Book Synopsis Quantifying Radiation Damage Through Stored Energy Released During Defect Annealing in Metals by : Charles Arthur Hirst
Download or read book Quantifying Radiation Damage Through Stored Energy Released During Defect Annealing in Metals written by Charles Arthur Hirst and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With full knowledge of a material's atomistic structure, it is possible to predict any macroscopic property of interest. In practice, this is hindered by limitations of the chosen characterisation technique. For example, transmission electron microscopy (TEM) is unable to detect the smallest and most numerous defects in irradiated metals. Instead of spatial characterisation, defects can be detected and quantified through their excess energy.
Book Synopsis Using Molecular Dynamics Simulations to Quantify the Energy Stored in Irradiation Defects in Tungsten and Aluminum by : Sean Lowder

This book was released on 2017 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation damage in materials can create potentially catastrophic effects by causing failure in critical reactor components. In order to prevent such failures, it is imperative that this damage is understood and quantified. Currently, displacements-per-atom (DPA) is the most common form of expressing the amount of radiation a material has received. With its limitations on accurately expressing how much damage remains in a material post-irradiation, the DPA does not provide enough information about an exposed material to fully understand how it is has been compromised. One suggested replacement for the DPA is the Wigner stored energy, which is a measurement of the energy stored in radiation defects. To prepare for future experimental work, irradiation in tungsten and aluminum was simulated and analyzed for trends in defect energy. With increasing amounts of radiation exposure, it was found that the average energy associated with individual defects remains constant, but that defect clustering and dislocation forming increases. Simulations were then performed to mimic the process of calorimetry heating. These simulations showed how the defects annealed out with heating, and the results will be extrapolated to predict experimental results. If Wigner energy can be successfully measured and characterized, it can become a more universal and reliable way of expressing radiation damage, improving safety throughout the nuclear industry.
Book Synopsis Defects and Radiation Damage in Metals by : M. W. Thompson
Download or read book Defects and Radiation Damage in Metals written by M. W. Thompson and published by Cambridge University Press. This book was released on 1974-09-12 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of radiation damage in solids generally has been stimulated by the technological demands of nuclear energy and space research. Professor Thompson's 1969 book discusses the basic atomic mechanisms which give rise to the main effects induced by radiation in metals, since it is in their relatively simple structures that the fundamental processes can be most easily identified. The first part of the book describes the nature of lattice defects in metal crystals. The presentation leads naturally into the discussion of radiation damage in the second part and recognises the important contribution that the study of irradiated metals has made to our general knowledge of defects. The wide coverage of this book includes developments in our understanding of collision cascades, of the clustering of point defects and the behaviour of impurities induced by irradiation.
Book Synopsis Radiation Damage Quantification in Elemental Copper Using Wigner Energy Storage by : Ki-Jana Carter
Download or read book Radiation Damage Quantification in Elemental Copper Using Wigner Energy Storage written by Ki-Jana Carter and published by . This book was released on 2017 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation damage in materials can cause critical components in fission and fusion reactors to fail with potentially catastrophic consequences. Radiation damage quantification is essential for understanding, predicting, and preventing such failures. The current unit of radiation damage, displacements per atom (DPA), is not a measurable quantity, and it is known to be an inaccurate measure of radiation damage. This project aims to quantify radiation damage accurately and measurably by characterizing the storage of energy in radiation-induced material defects, known as Wigner energy storage. In order to gain an atomistic understanding of radiation damage, the irradiation and calorimetry of elemental copper were simulated using molecular dynamics code. A custom defect analysis script was used to determine the energy stored as a function of irradiation energy and defect type. Wigner energy peaks were clearly visible in the calorimetry data, indicating that Wigner energy measurement is a plausible technique for quantifying radiation damage. Future work should focus on achieving more realistic heating rates and measuring Wigner energy storage experimentally using fast scanning calorimetry.

Book Synopsis Comprehensive Nuclear Materials by :
Download or read book Comprehensive Nuclear Materials written by and published by Elsevier. This book was released on 2020-07-22 with total page 4871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials in a nuclear environment are exposed to extreme conditions of radiation, temperature and/or corrosion, and in many cases the combination of these makes the material behavior very different from conventional materials. This is evident for the four major technological challenges the nuclear technology domain is facing currently: (i) long-term operation of existing Generation II nuclear power plants, (ii) the design of the next generation reactors (Generation IV), (iii) the construction of the ITER fusion reactor in Cadarache (France), (iv) and the intermediate and final disposal of nuclear waste. In order to address these challenges, engineers and designers need to know the properties of a wide variety of materials under these conditions and to understand the underlying processes affecting changes in their behavior, in order to assess their performance and to determine the limits of operation. Comprehensive Nuclear Materials, Second Edition, Seven Volume Set provides broad ranging, validated summaries of all the major topics in the field of nuclear material research for fission as well as fusion reactor systems. Attention is given to the fundamental scientific aspects of nuclear materials: fuel and structural materials for fission reactors, waste materials, and materials for fusion reactors. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource of information. Most of the chapters from the first Edition have been revised and updated and a significant number of new topics are covered in completely new material. During the ten years between the two editions, the challenge for applications of nuclear materials has been significantly impacted by world events, public awareness, and technological innovation. Materials play a key role as enablers of new technologies, and we trust that this new edition of Comprehensive Nuclear Materials has captured the key recent developments. Critically reviews the major classes and functions of materials, supporting the selection, assessment, validation and engineering of materials in extreme nuclear environments Comprehensive resource for up-to-date and authoritative information which is not always available elsewhere, even in journals Provides an in-depth treatment of materials modeling and simulation, with a specific focus on nuclear issues Serves as an excellent entry point for students and researchers new to the field
