Nuclear Issues

The just-concluded fourth and final nuclear security summit saw some serious progress, but also some missed opportunities.

At a meeting 23 and 24 March in Belgrade, US and Russian members of the Elbe Group – retired general officers from the military and intelligence services – declared that the risk of terrorism, both conventional and nuclear, is growing.  They urged that special attention must be given to preventing Daesh, al Qaeda, and other terrorist organizations which have declared openly their desire to gain weapons of mass destruction, from obtaining them.

As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security.

Matthew Bunn, William Tobey, and I have a new op-ed in The Hill’s Congress Blog, “Don’t weaken our defenses against nuclear smuggling.” We wrote it in response to proposed legislation that would prohibit funding for fixed radiation detectors to catch nuclear smugglers – both for installing new ones and even for maintaining the ones U.S. taxpayers have already paid billions to install.

On April 28, the Project on Managing the Atom joined the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey, The Netherlands government, and the United Nations Office for Disarmament Affairs (UNODA) in convening nuclear nonproliferation experts from around the world at the United Nations to participate in a Symposium on the 2015 Nonproliferation Treaty (NPT) Review Conference.

On February 16, 2015, Professor of Practice Matthew Bunn presented "The Iranian Nuclear Crisis: Next Steps" for the Harvard Project for Asian and International Relations.

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.

This week’s Nuclear Security Summit in The Hague was understandably overshadowed by the continuing international response to Russia’s illegal annexation of Crimea. One aspect of the Ukraine crisis that deserves more attention is how the current standoff will impact the future of nuclear security cooperation between the United States and Russia.

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.
