Safe and secure transport and storage of radioactive materials are essential for sustainable nuclear fuel cycle. The basic technologies are matured, but they have been progressively developed to make transport and storage safer and more secure. Safe and secure culture that encourages a questioning and learning attitude and that discourages complacency should be fostered and maintained. This book provides current basis of safe and secure transport and storage so that those technologies can be readily traced, improved, or modified, if necessary, for and by the future generations.This book overviews current available information in the literature. It also covers advanced technology on similar subjects in the literature. On top of that, new and valuable subjects are introduced for readers to grasp the wide spectrum of the safe and secure transport and storage technology. The contents are arranged and divided into three sections, I: Safety of Transport, II: Safety of Storage, III: Security of Transport and Storage.
