Originally published in 1983, this book presents both the technical and political information necessary to evaluate the emerging threat to world security posed by recent advances in uranium enrichment technology. Uranium enrichment has played a relatively quiet but important role in the history of efforts by a number of nations to acquire nuclear weapons and by a number of others to prevent the proliferation of nuclear weapons. For many years the uranium enrichment industry was dominated by a single method, gaseous diffusion, which was technically complex, extremely capital-intensive, and highly inefficient in its use of energy. As long as this remained true, only the richest and most technically advanced nations could afford to pursue the enrichment route to weapon acquisition. But during the 1970s this situation changed dramatically. Several new and far more accessible enrichment techniques were developed, stimulated largely by the anticipation of a rapidly growing demand for enrichment services by the world-wide nuclear power industry. This proliferation of new techniques, coupled with the subsequent contraction of the commercial market for enriched uranium, has created a situation in which uranium enrichment technology might well become the most important contributor to further nuclear weapon proliferation. Some of the issues addressed in this book are: A technical analysis of the most important enrichment techniques in a form that is relevant to analysis of proliferation risks; A detailed projection of the world demand for uranium enrichment services; A summary and critique of present institutional non-proliferation arrangements in the world enrichment industry, and An identification of the states most likely to pursue the enrichment route to acquisition of nuclear weapons.

Addresses high enriched uranium (HEU) management of declared excesses, non-proliferation programmes and options for the use of HEU stockpiles. Also addressed are the influence of low enriched uranium derived from surplus HEU on the global market for uranium, technical issues associated with utilization and the disposition of HEU.

The 1968 Nuclear Non-proliferation Treaty has proven the most complicated and controversial of all arms control treaties, both in principle and in practice. Statements of nuclear-weapon States from the Cold War to the present, led by the United States, show a disproportionate prioritization of the non-proliferation pillar of the Treaty, and an unwarranted underprioritization of the civilian energy development and disarmament pillars of the treaty. This book argues that the way in which nuclear-weapon States have interpreted the Treaty has laid the legal foundation for a number of policies related to trade in civilian nuclear energy technologies and nuclear weapons disarmament. These policies circumscribe the rights of non-nuclear-weapon States under Article IV of the Treaty by imposing conditions on the supply of civilian nuclear technologies. They also provide for the renewal and maintaintenance, and in some cases further development of the nuclear weapons arsenals of nuclear-weapon States. The book provides a legal analysis of this trend in treaty interpretation by nuclear-weapon States and the policies for which it has provided legal justification. It argues, through a close and systematic examination of the Treaty by reference to the rules of treaty interpretation found in the 1969 Vienna Convention on the Law of Treaties, that this disproportionate prioritization of the non-proliferation pillar of the Treaty leads to erroneous legal interpretations in light of the original balance of principles underlying the Treaty, prejudicing the legitimate legal interests of non-nuclear-weapon States.

Thirty years ago, in 1988, the United States secretly moved to end once and for all Taiwan's nuclear weapons program, just as it was nearing the point of being able to rapidly break out to build nuclear weapons. Because intense secrecy has followed Taiwan's nuclear weapons program and its demise, this book is the first account of that program's history and dismantlement. Taiwan's nuclear weapons program made more progress and was working on much more sophisticated nuclear weapons than publicly recognized. It came dangerously close to fruition. Taipei excelled at the misuse of civilian nuclear programs to seek nuclear weapons and implemented capabilities to significantly reduce the time needed to build them, following a decision to do so. Despite Taiwan's efforts to hide these activities, the United States was able to gather incriminating evidence that allowed it to act, effectively denuclearizing a dangerous, destabilizing program, that if left unchecked, could have set up a potentially disastrous confrontation with the People's Republic of China (PRC). The Taiwan case is rich in findings for addressing today's nuclear proliferation challenges.

Finally, the book assesses the contribution of international assistance programmes to the denuclearization process under way in the former Soviet Union.

In the fall of 2010, the Office of the U.S. Department of Energy's (DOE's) Secretary for Science asked for a National Research Council (NRC) committee to investigate the prospects for generating power using inertial confinement fusion (ICF) concepts, acknowledging that a key test of viability for this concept-ignition -could be demonstrated at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) in the relatively near term. The committee was asked to provide an unclassified report. However, DOE indicated that to fully assess this topic, the committee's deliberations would have to be informed by the results of some classified experiments and information, particularly in the area of ICF targets and nonproliferation. Thus, the Panel on the Assessment of Inertial Confinement Fusion Targets ("the panel") was assembled, composed of experts able to access the needed information. The panel was charged with advising the Committee on the Prospects for Inertial Confinement Fusion Energy Systems on these issues, both by internal discussion and by this unclassified report. A Panel on Fusion Target Physics ("the panel") will serve as a technical resource to the Committee on Inertial Confinement Energy Systems ("the Committee") and will prepare a report that describes the R&D challenges to providing suitable targets, on the basis of parameters established and provided to the Panel by the Committee. The Panel on Fusion Target Physics will prepare a report that will assess the current performance of fusion targets associated with various ICF concepts in order to understand: 1. The spectrum output; 2. The illumination geometry; 3. The high-gain geometry; and 4. The robustness of the target design. The panel addressed the potential impacts of the use and development of current concepts for Inertial Fusion Energy on the proliferation of nuclear weapons information and technology, as appropriate. The Panel examined technology options, but does not provide recommendations specific to any currently operating or proposed ICF facility.
