This book offers a comprehensive exploration of the effects on national/state security policy and discourse of the production, storage, transportation, safeguarding, export and use of enriched uranium and by extension, plutonium. Hubbard looks closely at a wide range of interlinked geo-political, security and technical issues as well as challenges for national and global governance in the dual fields of nuclear power generation and the proliferation of nuclear weapons materials and technologies. This book contributes to a new understanding of one of the most serious security implications inherent in the current rapid growth in nuclear power generation. Furthermore, it examines the chances for success of these efforts, as well as the costs of failing to account safely for the latent dangers to Homeland Security posed by the diversion beyond the nuclear fuel cycle, and subsequent misuse, of enriched uranium and plutonium. Extremely well written, this book contains a wealth of technical information but does not over rely on technical jargon or complexities.
