Nuclear Issues

Based on multi-archival research, this article explores the significance of Franco-Indian nuclear relations against the backdrop of Anglo-American endeavours to censor information related to atomic energy and to secure control of strategic minerals during the early Cold War.

"A mere three-and-a-half years after the catastrophic nuclear events at Fukushima Daiichi in Japan, it is still too early to draw conclusions about how Fukushima has affected global nuclear energy policy. The first signs of future policy do, however, seem to indicate that there will be no major changes in nuclear power forecasts in the immediate future."

Characterization of the anticipated performance of energy technologies to inform policy decisions increasingly relies on expert elicitation. Knowledge about how elicitation design factors impact the probabilistic estimates emerging from these studies is, however, scarce. We focus on nuclear power, a large-scale low-carbon power option, for which future cost estimates are important for the design of energy policies and climate change mitigation efforts. We use data from three elicitations in the USA and in Europe and assess the role of government research, development, and demonstration (RD&D) investments on expected nuclear costs in 2030.

Probabilistic estimates of the cost and performance of future nuclear energy systems under different scenarios of government research, development, and demonstration (RD&D) spending were obtained from 30 U.S. and 30 European nuclear technology experts. The majority expected that such RD&D would have only a modest effect on cost, but would improve performance in other areas, such as safety, waste management, and uranium resource utilization. The U.S. and E.U. experts were in relative agreement regarding how government RD&D funds should be allocated, placing particular focus on very high temperature reactors, sodium-cooled fast reactors, fuels and materials, and fuel cycle technologies.

In order to expand nuclear power energy in desalination and increase competitiveness in the global nuclear power market, many developed countries with strong nuclear technology have realized the importance of Small Modular Reactors (SMR) and initiated heavy research and development in SMR．The Advanced Small Pressurized Water Reactor (ASPWR) is characterized by great advantages, both in safety and economic mattters. It can be used in remote power grids and replace mid／small size fossil plants economically．This paper reviews the history and current status of SMR and ASPWR，and also discusses the design concepts, safety features and other advantages thereof.

Recent national trends in investments in global energy research, development, and demonstration (RD&D) are inconsistent around the world. Public RD&D investments in energy are the metric most commonly used in international comparative assessments of energy-technology innovation, and the metric employed in this article. Overall, the data indicate that International Energy Agency (IEA) member country government investments have been volatile: they peaked in the late 1970s, declined during the subsequent two decades, bottomed out in 1997, and then began to gradually grow again during the 2000s.

"...Iran's nuclear strategy is based on mastering the independent nuclear fuel cycle, seeking a cooperative relationship with the International Atomic Energy Agency (IAEA) according to its Safeguards Agreement, and enhancing regional and global nuclear disarmament. While Iran's progress in moving forward with the elements of this strategy brings challenges for the P5 + 1 group—namely reaching consensus on the mutual interests of all concerned parties—Iran supports continued discussions with this group to find a result acceptable to all parties in the diplomatic process."

"Without energy, there is no economy. Without climate, there is no environment. Without economy and environment, there is no material well-being, no civil society, no personal or national security. The overriding problem associated with these realities, of course, is that the world has long been getting most of the energy its economies need from fossil fuels whose emissions are imperiling the climate that its environment needs."

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."

"With the issuance of the latest Intergovernmental Panel on Climate Change report in February 2007 the world faces the stark reality that it must reduce greenhouse gas emissions immediately or face dire consequences. Nuclear energy provides a reliable source of carbon dioxide–free electricity, and a global expansion of nuclear power could replace fossil-fuel fired plants significantly within twenty to fifty years. One of the main impediments to the expansion of nuclear energy is the unresolved problem of what to do with the nuclear waste. Though nuclear power has been with us almost fifty years, to date, not one of the 30 countries with nuclear power plants has opened a nuclear waste repository...."
