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?

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.

Even as this paper was being written and edited, U.S.-Russian relations have warmed and chilled. Today, as we are about to go to press, marks a particularly chilly period in recent history, with the cancellation of a planned Moscow Summit in September 2013. To some, this cold spell might signal an inapt moment to consider issues related to transcending mutual deterrence. Such a view would overlook the aims of the paper, which attempts to assess the central and enduring interests of the United States and Russia, the extent to which they coincide or conflict, and whether or not in light of these interests mutual deterrence should remain a fundamental feature of the relationship.

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.

In the Foreword to this paper by Andrei Kokoshin, Belfer Center Director Graham Allison writes: "The global nuclear order is reaching a tipping point. Several trends are advancing along crooked paths, each undermining this order. These trends include North Korea’s expanding nuclear weapons program, Iran’s continuing nuclear ambitions, Pakistan’s increasing instability, growing doubts about the sustainability of the nonproliferation regime in general, and terrorist groups’ enduring aspirations to acquire nuclear weapons. Andrei Kokoshin, deputy of the State Duma and former secretary of Russia’s Security Council, analyzes these challenges that threaten to cause the nuclear order to collapse in the following paper."

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.”
