This book was released on 1997 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of initiating the stress-corrosion crack growth comprises following six elementary processes; namely, (I) the incubation period, (II) the process of nucleating the corrosion pits (or corrosion crevices), (III) the process of the growth of pits (or crevices), (IV) the process of initiating microcracks, (V) the process of the propagation of microcracks, (VI) the process of coalescing the microcracks, leading into the process of steady propagation of the main crack. The processes I, III, and V fall into the category of the deterministic process, while the processes II, IV, and VI the stochastic process. This paper deals with the last three stochastic elementary processes by analyzing the stress-corrosion cracking behavior for each stage, and examines the models developed thereby to predict the initiation life of each. Following observations and conclu-sions have been made: (1) the critical pit depth to initiate the microcrack is approximately 20 ?m for the carbon steel, and the micro-cracks are non-propagative semicircular cracks of approximately 50 ?m in depth; (2) the processes II of the pit nucleation, IV of the microcrack initiation, and VI of the microcrack coalescence can all be represented to the Poissonian stochastic process; (3) inasmuch as the total crack-initiation life is determined by a stochastic process comprising these Poissonian processes concatenated in series, the probability distribution of the life leading to the onset of steady propagation of a main crack can be represented by the exponential distribution; (4) the applied stress exerts its influence mainly on the rate of proliferation of microcracks, but hardly on the propagation of microcrack, critical pit depth, and the probability of the pit's gener-ating microcracks; and (5) inasmuch as the proliferation rate of microcrack is represented by a linear function in applied stress, the distribution lower limit of the main-crack initiation life is in inverse proportion to the applied stress.

Available in PDF, EPUB and Kindle. Book excerpt: Stress corrosion cracking is a major problem in light water nuclear reactors, whether pressurised water reactors (PWRs) or boiling water reactors (BWRs). The nuclear industry needs to be able to predict the service life of these power plants and develop appropriate maintenance and repair practices to ensure safe long term operation. This important book sums up key recent research on corrosion in light water reactors and its practical applications.The book is divided into four parts. It begins with an overview of materials degradation due to stress corrosion, corrosion potential monitoring and passivation. Part two summarises research on susceptibility of materials to stress corrosion cracking and the ways it can be initiated. The third part of the book considers stress corrosion crack propagation processes whilst the final part includes practical case studies of corrosion in particular plants. The book reviews corrosion in a range of materials such as low alloy steels, stainless steels and nickel-based alloys.With its distinguished editor and team of contributors, Corrosion issues in light water reactors is a standard work for the nuclear industry. - Summarises key recent research on corrosion in light water reactors - Includes practical case studies

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
