Reducing the Use of Highly Enriched Uranium in Civilian Research Reactors is a report of the Committee on the Current Status of and Progress Toward Eliminating Highly Enriched Uranium Use in Fuel for Civilian Research and Test Reactors. The committee was established by the Nuclear and Radiation Studies Board, Division on Earth and Life Studies and the National Academies of Sciences, Engineering, and Medicine. The report is the result of a congressionally mandated study (P.L. 112-239, Section 31781) to assess improvement in reducing highly enriched uranium use in fuel for civilian research and test reactors.

Belfer Center Senior Fellow William Tobey is a member of the Committee that produced the report.

As nuclear negotiations with Iran near their final stage, the question of inspections has come to the fore. If a final agreement is reached, inspections will be a principal means of assuring that Iran does not develop nuclear weapons, either by “breakout” at declared facilities, or by “sneakout” using secret sites. Given the importance being placed on inspections, what type will be necessary?  What inspection and verification regime will be needed to facilitate compliance, detect violations, and ensure effective enforcement?

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.

What would be the consequences if the interim deal became, de facto, permanent?  Does the interim deal have gaps that would be fatal to any long-term arrangement?  What are the consequences if no deal is reached?  And, are such consequences better or worse than those resulting from an extension of the interim deal, or from a deal that fails to meet minimum acceptable standards? These questions, among others, were addressed at a private roundtable discussion hosted by the Wisconsin Project on Nuclear Arms Control on April 25, 2014.

This paper analyzes the contribution that best practices can make to the field of nuclear security by doing the following:

• Defining what is meant by best practice
• Specifying a methodology for deriving it
• Understanding the resulting characteristics of the method
• Comparing its pros and cons to other methods contributing to security, such as guidelines and regulations

Twenty years ago Russia and fourteen other newly-independent states emerged from the ruins of the Soviet empire, many as nations for the first time in history. As is typical in the aftermath of the collapse of an empire, this was followed by a period of chaos, confusion, and corruption. As the saying went at the time, “everything is for sale.” At that same moment, as the Soviet state imploded, 35,000 nuclear weapons remained at thousands of sites across a vast Eurasian landmass that stretched across eleven time zones. 

Today, fourteen of the fifteen successor states to the Soviet Union are nuclear weapons-free. This paper will address the question: how did this happen? Looking ahead, it will consider what clues we can extract from the success in denuclearizing fourteen post-Soviet states that can inform our non-proliferation and nuclear security efforts in the future. These clues may inform leaders of the U.S., Russia, and other responsible nations attending the Seoul Nuclear Security Summit on March 26-27, 2012. The paper will conclude with specific recommendations, some exceedingly ambitious that world leaders could follow to build on the Seoul summit’s achievements against nuclear terrorism in the period before the next summit in 2014. One of these would be to establish a Global Alliance Against Nuclear Terrorism.

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.

Researchers from the United States and Russia have issued a joint assessment of the global threat of nuclear terrorism, warning of a persistent danger that terrorists could obtain or make a nuclear device and use it with catastrophic consequences. The first joint threat assessment by experts from the world’s two major nuclear powers concludes: “If current approaches toward eliminating the threat are not replaced with a sense of urgency and resolve, the question will become not if but when, and on what scale, the first act of nuclear terrorism occurs.”

"The focus of the workshop was on the demonstration stage of the technology innovation cycle. Current policies do not adequately address the private sector’s inability to overcome the demonstration "valley of death" for new energy technologies. Investors and financiers fear that the technology and operational risks at this stage of the cycle remain too high to justify the level of investment to build a commercial-sized facility."

"There is broad political consensus that the current energy system in the United States is unable to meet the nation's future energy needs, from the security, environment, and economic perspectives. New energy technologies are required to increase the availability of domestic energy supplies, to reduce the negative environmental impacts of our energy system, to improve the reliability of current energy infrastructure (e.g., smart grid, energy storage), and to increase energy efficiency throughout the economy."
