This volume offers a wide-ranging examination and discussion of the International Atomic Energy Agency’s (IAEA) past, present and future as it enters its seventh decade. Including contributions from leading experts across the globe, the book assesses the historical record of the IAEA; the issues and challenges it faces at present; and its future prospects. In doing so, it addresses the primary missions of the IAEA outlined in the IAEA’s statute, i.e., to safeguard and promote the peaceful uses of nuclear energy, as well as the missions over which it is expanding its mandate, including nuclear safety and security. The volume is divided into two parts: Part I focuses on historical recollections and reflections of participants in key events, ranging from a personal account of the initial negotiations of the IAEA to an account by its chairman on the dynamics of the Board of Governors in recent years. Part II covers current and future issues in the IAEA’s role in nuclear safeguards, the peaceful uses of nuclear energy, and nuclear safety and security. This book will be of much interest to students of nuclear proliferation and arms control, global governance and international security in general.
