Nuclear Issues

Two conditions are clear as the U.S. and Russian Presidents prepare meet in Helsinki. First, U.S.-Russian relations are arguably at their lowest point since the collapse of the Soviet Union and the end of the Cold War. Second, both presidents have domestic realities that constrain their flexibility to achieve compromise in the many areas that have caused relations to falter.

On 16 July in Helsinki, President of the Russian Federation Vladimir Putin will meet his American colleague Donald Trump. The leaders will discuss a number of complicated questions, but the summit will be a success, even if the government leaders cannot reach agreement - so thinks retired Brigadier General and Associate Fellow at the Belfer Center for Science and International Affairs, Harvard Kennedy School, Kevin Ryan. Ryan talked to "Eurasia Expert" about the significance of the meeting between the American and Russian leaders for relations between the two countries, the future of NATO, and explained how American space forces will differ from Russian or Chinese space forces.

Characterizing the future performance of energy technologies can improve the development of energy policies that have net benefits under a broad set of future conditions. In particular, decisions about public investments in research, development, and demonstration (RD&D) that promote technological change can benefit from (1) an explicit consideration of the uncertainty inherent in the innovation process and (2) a systematic evaluation of the tradeoffs in investment allocations across different technologies. To shed light on these questions, over the past five years several groups in the United States and Europe have conducted expert elicitations and modeled the resulting societal benefits. In this paper, the authors discuss the lessons learned from the design and implementation of these initiatives.

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.

Dramatic growth in nuclear energy would be required for nuclear power to provide a significant part of the carbon-free energy the world is likely to need in the 21st century, or a major part in meeting other energy challenges. This would require increased support from governments, utilities, and publics around the world. Achieving that support is likely to require improved economics and major progress toward resolving issues of nuclear safety, proliferation-resistance, and nuclear waste management. This is likely to require both research, development, and demonstration (RD&D) of improved technologies and new policy approaches.
