Waste Immobilization in Glass and Ceramic Based Hosts

Radioactive, Toxic and Hazardous Wastes

• Gebundenes Buch

Produktbeschreibung

The problem of what to do with waste materials both radioactive and, more recently, non-radioactive, is an increasingly important environmental and political issue. Radioactive waste management practices vary worldwide but currently the most common method is to turn highly radioactive waste into a vitrified product, in order to render it passively safe before disposal. With mounting pressure on land-fill sites, and increased environmental concern, the issue of toxic and hazardous waste management must also be properly addressed. This book brings together all aspects of waste immobilization, draws comparisons between the different types of wastes and treatments, and outlines where lessons learnt by the nuclear industry may be usefully applied in the treatment of non-radioactive wastes. A wide range of topics is covered, including vitrification techniques, ceramic and glass-ceramic wasteforms, novel hosts, toxic and hazardous wastes, influence of microbial activity, and the treatment of new generation wastestreams. Waste Immobilization in Glass and Ceramic Based Hosts provides an up-to-date reference source at this critical time, when the need for low carbon energy sources has brought nuclear power back to the forefront, and non-radioactive toxic and hazardous wastes pose an increasing threat to the environment.

Autorenporträt

Ian Donald, Atomic Weapons Establishment (AWE), UK. Ian Donald has specialised in various areas of glass technology for over 30 years. After receiving a PhD from the University of Leeds? in 1973 he continued with postdoctoral studies at the University of Warwick. This was followed by research on metallic glasses at the University of Sheffield.?Subsequently, Dr. Donald joined the Atomic Weapons Research Establishment (later to become the Atomic Weapons Establishment,?ARE) in 1981. He was promoted to the grade of Distinguished Scientist in 2002, and was awarded the John Challens Medal for Lifetime Achievement by AWE in 2006. His work at AWE?has included a diverse range of topics and has covered speculative research on a variety of glass, ceramic and glass-ceramic materials, as well as component development programmes including the research and development of chemically strengthened glasses with frangible (command-break) properties, glass-coated microwire, glass- and glass-ceramic-to-metal seal devices and coatings, glass and glass-ceramic matrix composites and, over the last 14 years, glasses and ceramics as hosts for immobilizing radioactive wastes. Over this period, Dr Donald has presented many papers at international conferences on waste-related topics. Dr Donald is an elected member of national and international technical committees on glass including the Basic Science and Technology Committee of the Society of Glass Technology together with the Committee on Nucleation, Crystallization and Glass-Ceramics of the International Commission on Glass, representing the UK. He is also a Fellow of both the Institute of Materials, Minerals and Mining and the Society of Glass Technology, is an Associate Member of the Institute of Physics, has served time as a Visiting Professor at the University of Reading, is author or co-author of over 100 technical publications in the open literature, including a book written at the invitation of the Society of Glass Technology on Glass-to-Metal Seals, and is a member of the EPSRC Peer Review College.
