Book excerpt: The surplus of plutonium in the world is both an important security issue, and a fact with implications for nuclear energy and environmental policy internationally. The two perspectives are inextricably intertwined in considering options for dealing with the plutonium surplus. It was for this reason that two research programmes at the Royal Institute of International Affairs - respectively on Energy and Environment, and on International Security - jointly approached NATO with a view to organising a work shop on the issue. It was most welcome then to learn that the NATO Science Programe was already supporting plans for a workshop on the issue, initiated by Richard Garwin, and we were pleased to accept the resulting invitation to host that workshop. DrGarwin prepared the initial agenda and established contacts and initial approaches to many of the participants; we were able to develop the agenda further and extend participation in some complementary ways. The result was a most lively and broad-ranging internation al and inter-disciplinary discussion. As the hosts, the RIIA was also given lead responsibility for producing the pro ceedings of the workshop as a publication for NATO. Many of the papers to the work shop are more technical than usually involved in a workshop at the Royal Institute. Yet this is an area in which the policy options are unusually dependent upon a good under standing of the technical issues. which themselves are often a matter of dispute.

Book excerpt: In 2018, the National Academies of Sciences, Engineering, and Medicine issued an Interim Report evaluating the general viability of the U.S. Department of Energy's National Nuclear Security Administration's (DOE-NNSA's) conceptual plans for disposing of 34 metric tons (MT) of surplus plutonium in the Waste Isolation Pilot Plant (WIPP), a deep geologic repository near Carlsbad, New Mexico. It provided a preliminary assessment of the general viability of DOE-NNSA's conceptual plans, focused on some of the barriers to their implementation. This final report addresses the remaining issues and echoes the recommendations from the interim study.

Book excerpt: This NATO Advanced Research Workshop on Disposal of Weapons Plutonium is a follow-up event to two preceding workshops, each dealing with a special subject within the overall disarmament issue: "Disposition of Weapon Plutonium", sponsored by the NATO Science Committee. The first workshop of this series was held at the Royal Institute of International Affairs in London on 24-25 January 1994, entitled "Managing the Plutonium Surplus, Applications, and Options". Its over all goal was to clarify the current situation with respect to pluto nium characteristics and availability, the technical options for use or disposal, and their main technical, environmental, and economic constraints. In the immediate term, plutonium recovered from dismantled nuclear warheads will have to be stored securely, and under international safeguards if possible. In the intermediate term, the principal alter natives for disposition of this plutonium are: irradiation in mixed oxide (MOX) fuel assemblies in existing commercial light-water reac tors or in specially adapted light-water reactors capable of operation with full cores of MOX fuel .and irradiation in future fast reactors. Another option is to blend plutonium with high-level waste as it is vitrified for final disposal in a geologic repository. In both cases, the high radioactivity of the resulting products provides "self shielding" and prevents separation of plutonium without already developed and available sophisticated technology. The so-called "spent fuel standard" as an effective protection barrier is - quired in either case.

Book excerpt: Within the next decade, many thousands of U.S. and Russian nuclear weapons are slated to be retired as a result of nuclear arms reduction treaties and unilateral pledges. Hundreds of tons of plutonium and highly enriched uranium will no longer be needed for weapons purposes and will pose urgent challenges to international security. This is the supporting volume to a study by the Committee on International Security and Arms Control which dealt with all phases of the management and disposition of these materials. This technical study concentrates on the option for the disposition of plutonium, looking in detail at the different types of reactors in which weapons plutonium could be burned and at the vitrification of plutonium, and comparing them using economic, security and environmental criteria.

This book was released on 2013-06-29 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: MOX fuel, a mixture of weapon-grade plutonium and natural or depleted uranium, may be used to deplete a portion of the world's surplus of weapon-grade plutonium. A number of reactors currently operate in Europe with one-third MOX cores, and others are scheduled to begin using MOX fuels in both Europe and Japan in the near future. While Russia has laboratory-scale MOX fabrication facilities, the technology remains under study. No fuels containing plutonium are used in the U.S. The 25 presentations in this book give an impressive overview of MOX technology. The following issues are covered: an up to date report on the disposition of ex-weapons Pu in Russia; an analysis of safety features of MOX fuel configurations of different reactor concepts and their operating and control measures; an exchange of information on the status of MOX utilisation in existing power plants, the fabrication technology of various MOX fuels and their behaviour in practice; a discussion of the typical national approaches by Russia and the western countries to the utilisation of Pu as MOX fuel; an introduction to new ideas, enhancing the disposition option of MOX fuel exploitation and destruction in existing and future advanced reactor systems; and the identification of common research areas where defined tasks can be initiated in cooperative partnership.

Book excerpt: A survey of recent developments in the field of plutonium disposal by the application of advanced nuclear systems, both critical and subcritical. Current national R&D plans are summarized. The actinide-fuelled critical reactors are associated with control problems, since they tend to have a small delayed neutron fraction coupled with a small Doppler effect and a positive void coefficient. Current thinking is turning to accelerator-driven subcritical systems for the transmutation of actinides. The book's conclusion is that the various systems proposed are technically feasible, even though not yet technically mature. The book presents a unique summary and evaluation of all relevant possibilities for burning surplus plutonium, presented by experts from a variety of different disciplines and interests, including the defence establishment. The obvious issue - the non-proliferation of nuclear weapons - is vital, but the matter represents a complex technological challenge that also requires an assessment in economic terms.

This book was released on 1996-12-11 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-lived radioactive materials from the operation of nuclear power plants and from the maintenance and decommissioning of nuclear weapons pose environmental and security risks. Technologies that would counter such risks are under intense study worldwide. One such technology, transmutation by nuclear means into shorter-lived materials, was the subject of an international workshop in Russia, where the need for a viable solution of this problem is particularly strong. Current problems of that technology and future perspectives and cooperative research possibilities involving Russian and East European facilities are discussed by scientists from Russia, the United States and seven other countries representing basic research institutes, former nuclear weapons laboratories and nuclear industries. Computer modeling, data bases and experimental investigations needed for the conceptualization of demonstration, prototype and production facilities are treated in detail. Progress on the planning and construction of the first demonstration facilities is also described. From these proceedings it becomes evident that the problems inherent in radioactive waste accumulation can be solved only by international cooperation in which conventional methods are supplemented by new technologies, and that such a solution may require a sustained effort comparable to the Manhattan Project and the analogous project in the former USSR at the beginning of the nuclear era.

Its editor is Joseph Rotblat, the 1995 Nobel Peace Prize winner. The volume assesses recent efforts by scholars, military leaders, and political figures in advocating the elimination of nuclear weapons. It brings to focus the major dilemmas of disarmament, including verification, nuclear theft, and diplomatic and security issues; and argues for why these obstacles must be overcome. Finally, a comprehensive review of the steps needed to achieve a nuclear-weapon-free world is presented. }Over the past decade the concept of a world free of all nuclear weapons has transformed from a fanciful dream to a subject of serious study and action. Will it be possible for the international community to agree not simply to reduce the number of nuclear weapons to low levels, but to reduce it to zero?

Book excerpt: The "VOLGA" conferences, hosted in odd-numbered years by the Department of Theoretical and Experimental Reactor Physics of the Moscow Engineering Physics Institute (MEPhI), are some of the most prestigious technical meetings held in Russia. Traditionally, these conferences present the opportunity for reactor physicists from around the world to gather at MEPhI's holiday camp on the banks of the Volga river (near Tver) to exchange ideas and explore innovative concepts related to nuclear power development. In 1997, NATO became involved in the "VOLGA" meetings for the first time by co-sponsoring "VOLGA97" as an advanced research workshop. This workshop broke with tradition a bit in that the venue was moved from MEPhI's holiday camp to a location nearer Moscow. The workshop program was effectively organized in order to cover a broad range of topics relating to the theme of the meeting. Generally, the papers concerned safety related questions associated with utilizing both weapons-grade and reactor-grade plutonium in the nuclear fuel cycle, including facility requirements, licensing issues, proliferation risks, and a variety of advanced concepts for alternative fuel cycles. The program contained a total of ninety-nine papers presented in five days of sessions.

Available in PDF, EPUB and Kindle. Book excerpt: In the wake of California's energy crisis, policymakers' rush to satisfy growing demand requirements may run the risk of naively ignoring the larger issues and dangers associated with increased reliance on nuclear power. A connection between national nuclear power programs and nuclear proliferation can be found in the strategic initiatives of North Korea, Iraq, Iran, India, and Pakistan. In response to this threat, the Nuclear Control Institute has assembled a consortium of experts to underscore the connection that exists between nuclear power and the proliferation of nuclear weapons. They evaluated proliferation risks and proposed viable alternative energy sources. This volume includes the analysis of such respected thinkers as Pulitzer Prize-winning author Richard Rhodes; Rep. Edward Markey (D-Mass.); Amory Lovins, CEO of the Rocky Mountain Institute; and Amb. Robert Galucci, dean of the Georgetown University School of Foreign Service.

This book was released on 2003-06-09 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of nuclear materials for the national defense was an intense, nationwide effort that began with the Manhattan Project and continued throughout the Cold War. Now many of these product materials, by-products, and precursors, such as irradiated nuclear fuels and targets, have been declared as excess by the Department of Energy (DOE). Most of this excess inventory has been, or will be, turned over to DOE's Office of Environmental Management (EM), which is responsible for cleaning up the former production sites. Recognizing the scientific and technical challenges facing EM, Congress in 1995 established the EM Science Program (EMSP) to develop and fund directed, long-term research that could substantially enhance the knowledge base available for new cleanup technologies and decision making. The EMSP has previously asked the National Academies' National Research Council for advice for developing research agendas in subsurface contamination, facility deactivation and decommissioning, high-level waste, and mixed and transuranic waste. For this study the committee was tasked to provide recommendations for a research agenda to improve the scientific basis for DOE's management of its high-cost, high-volume, or high-risk excess nuclear materials and spent nuclear fuels. To address its task, the committee focused its attention on DOE's excess plutonium-239, spent nuclear fuels, cesium-137 and strontium-90 capsules, depleted uranium, and higher actinide isotopes.
