One of today's most serious concerns is the disposal of nuclear fuel waste; no other peacetime technology evokes such public disquiet. In this book, Dr. Wiles expertly describes the nature of radioactivity and nuclear power. The subject matter is presented in a clear and eloquent manner and the author discusses, in detail, the management of radioactive waste using the multi-barrier system as well as taking a rather unusual approach to risk assessment. Based on a precise knowledge of the chemical properties of radionuclides in spent fuel, The Chemistry of Nuclear Fuel Waste Disposal follows each principal radionuclide as it travels through numerous levels of obstruction. Findings show that only two radionuclides effectively reach the biosphere, and do so only after many thousands of years. This book is a must for anyone interested in nuclear waste disposal including the processes involved, the areas of uncertainty and the bases for statements about risk to human and other life. Policymakers and their advisors will find it an invaluable source of information on the state of knowledge and the scientific background for the recommendations on which policy decisions and investments will be made.
