Adequate supplies of electricity have allowed Japan to make impressive economic advances. But Japan can sustain these advances only with assured supplies of fuel. To this end, it diversifies both its type of power producing facilities and its sources of fuel. Nuclear power provides Japan 30% of its electricity today and by the end of the century it will grow to 40%. Japan is facing both an opportunity and a dilemma. Japan's opportunity to convert its nuclear power from the conventional uranium based fuel to the more expensive mix of plutonium and uranium fuel extends its fuel supply by up to ten years at a substantial dollar cost as well as a potential nuclear weapons proliferation cost. This study estimates that if Japan elects to fuel its reactors with mixed plutonium and uranium oxide the dollar cost alone would run from $135 million to $800 million per year over the conventional uranium fuel. This cost is compounded by the fact that plutonium - unlike reactor grade uranium - is weapons usable. Plutonium in the hands of Japan may attract other countries to also want plutonium. This study concludes that one means of assuring energy and minimizing the potential for weapons proliferation is to develop an international nuclear fuel bank that could supply countries with energy credits.

This book provides a readable and thought-provoking analysis of the issues surrounding nuclear fuel reprocessing and fast-neutron reactors, including discussion of resources, economics, radiological risk and resistance to nuclear proliferation. It describes the history and science behind reprocessing, and gives an overview of the status of reprocessing programmes around the world. It concludes that such programs should be discontinued. While nuclear power is seen by many as the only realistic solution to the carbon emission problem, some national nuclear establishments have been pursuing development and deployment of sodium-cooled plutonium breeder reactors, and plutonium recycling. Its proponents argue that this system would offer significant advantages relative to current light water reactor technology in terms of greater uranium utilization efficiency, and that separating out the long-lived plutonium and other transuranics from spent fuel and fissioning them in fast reactors would greatly reduce the duration of the toxicity of radioactive waste. However, the history of efforts to deploy this system commercially in a number of countries over the last six decades has been one of economic and technical failure and, in some cases, was used to mask clandestine nuclear weapon development programs. Covering topics of significant public interest including nuclear safety, fuel storage, environmental impact and the spectre of nuclear terrorism, this book presents a comprehensive analysis of the issue for nuclear engineers, policy analysts, government officials and the general public. "Frank von Hippel, Jungmin Kang, and Masafumi Takubo, three internationally renowned nuclear experts, have done a valuable service to the global community in putting together this book, which both historically and comprehensively covers the “plutonium age” as we know it today. They articulate in a succinct and clear manner their views on the dangers of a plutonium economy and advocate a ban on the separation of plutonium for use in the civilian fuel cycle in view of the high proliferation and nuclear-security risks and lack of economic justification." (Mohamed ElBaradei, Director General, International Atomic Energy Agency (1997-2009), Nobel Peace Prize (2005)) "The 1960s dream of a ‘plutonium economy’ has not delivered abundant low-cost energy, but instead has left the world a radioactive legacy of nuclear weapons proliferation and the real potential for nuclear terrorism. Kang, Takubo, and von Hippel explain with power and clarity what can be done to reduce these dangers. The governments of the remaining countries whose nuclear research and development establishments are still pursuing the plutonium dream should pay attention.” (Senator Edward Markey, a leader in the US nuclear-disarmament movement as a member of Congress since 1976) "The authors have done an invaluable service by putting together in one place the most coherent analysis of the risks associated with plutonium, and the most compelling argument for ending the practice of separating plutonium from spent fuel for any purpose. They have given us an easily accessible history of the evolution of thinking about the nuclear fuel cycle, the current realities of nuclear power around the world and, arguably most important, a clear alternative path to deal with the spent fuel arising from nuclear reactors for decades to centuries to come."

The March 11, 2011, Great East Japan Earthquake and tsunami sparked a humanitarian disaster in northeastern Japan. They were responsible for more than 15,900 deaths and 2,600 missing persons as well as physical infrastructure damages exceeding $200 billion. The earthquake and tsunami also initiated a severe nuclear accident at the Fukushima Daiichi Nuclear Power Station. Three of the six reactors at the plant sustained severe core damage and released hydrogen and radioactive materials. Explosion of the released hydrogen damaged three reactor buildings and impeded onsite emergency response efforts. The accident prompted widespread evacuations of local populations, large economic losses, and the eventual shutdown of all nuclear power plants in Japan. "Lessons Learned from the Fukushima Nuclear Accident for Improving Safety and Security of U.S. Nuclear Plants" is a study of the Fukushima Daiichi accident. This report examines the causes of the crisis, the performance of safety systems at the plant, and the responses of its operators following the earthquake and tsunami. The report then considers the lessons that can be learned and their implications for U.S. safety and storage of spent nuclear fuel and high-level waste, commercial nuclear reactor safety and security regulations, and design improvements. "Lessons Learned" makes recommendations to improve plant systems, resources, and operator training to enable effective ad hoc responses to severe accidents. This report's recommendations to incorporate modern risk concepts into safety regulations and improve the nuclear safety culture will help the industry prepare for events that could challenge the design of plant structures and lead to a loss of critical safety functions. In providing a broad-scope, high-level examination of the accident, "Lessons Learned" is meant to complement earlier evaluations by industry and regulators. This in-depth review will be an essential resource for the nuclear power industry, policy makers, and anyone interested in the state of U.S. preparedness and response in the face of crisis situations.

This book covers essential aspects of transmutation technologies, highlighting especially the advances in Japan. The accident at the Fukushima Daiichi Nuclear Power Plant (NPP) has caused us to focus attention on a large amount of spent nuclear fuels stored in NPPs. In addition, public anxiety regarding the treatment and disposal of high-level radioactive wastes that require long-term control is growing. The Japanese policy on the back-end of the nuclear fuel cycle is still unpredictable in the aftermath of the accident. Therefore, research and development for enhancing the safety of various processes involved in nuclear energy production are being actively pursued worldwide. In particular, nuclear transmutation technology has been drawing significant attention after the accident. This publication is timely with the following highlights: 1) Development of accelerator-driven systems (ADSs), which is a brand-new reactor concept for transmutation of highly radioactive wastes; 2) Nuclear reactor systems from the point of view of the nuclear fuel cycle. How to reduce nuclear wastes or how to treat them including the debris from TEPCO’s Fukushima nuclear power stations is discussed; and 3) Environmental radioactivity, radioactive waste treatment and geological disposal policy. State-of-the-art technologies for overall back-end issues of the nuclear fuel cycle as well as the technologies of transmutation are presented here. The chapter authors are actively involved in the development of ADSs and transmutation-related technologies. The future of the back-end issues in Japan is very uncertain after the accident at the Fukushima Daiichi NPP and this book provides an opportunity for readers to consider the future direction of those issues.

Learning from Fukushima began as a project to respond in a helpful way to the March 2011 triple disaster (earthquake, tsunami, and nuclear meltdown) in north-eastern Japan. It evolved into a collaborative and comprehensive investigation of whether nuclear power was a realistic energy option for East Asia, especially for the 10 member-countries of ASEAN, none of which currently has an operational nuclear power plant. We address all the questions that a country must ask in considering the possibility of nuclear power, including cost of construction, staffing, regulation and liability, decommissioning, disposal of nuclear waste, and the impact on climate change. The authors are physicists, engineers, biologists, a public health physician, and international relations specialists. Each author presents the results of their work.
