  • Michael Ojovan, Department of Materials Science and Engineering, University of Sheffield, UK
  • William Lee, Department of Materials, Imperial College London, UK

Drawing on the authors’ extensive experience in the processing and disposal of waste, An Introduction to Nuclear Waste Immobilisation, Second Edition examines the gamut of nuclear waste issues from the natural level of radionuclides in the environment to geological disposal of waste-forms and their long-term behavior. It covers all-important aspects of processing and immobilization, including nuclear decay, regulations, new technologies and methods. Significant focus is given to the analysis of the various matrices used, especially cement and glass, with further discussion of other matrices such as bitumen. The final chapter concentrates on the performance assessment of immobilizing materials and safety of disposal, providing a full range of the resources needed to understand and correctly immobilize nuclear waste.

Reviews

"The second edition of this book is a great opportunity to learn about the state-of-the-art of radioactive waste management, both from a scientific and a technical perspective. The book is made up of 21 short, clear, nicely-illustrated chapters covering most aspects of the problem…authors are well-known scientists with broad international experience…"--MaterialsToday.com, March 6, 2014

From first edition:
"The book is intended as an introductory text for postgraduate students and researchers in the field. In addition, it serves as an excellent source of knowledge for undergraduates (in physics, chemistry, geology, materials etc.) who require general information on nuclear waste and its immobilisation."--Dr. John Fernie, MATERIALS WORLD, May 2007
