Nuclear Issues

Former Deputy Secretary of Energy Elizabeth Sherwood-Randall is joining Harvard Kennedy School’s Belfer Center for Science and International Affairs as a Senior Fellow, the Center announced today. Sherwood-Randall, who has served in the White House and Departments of Energy and Defense, is returning to the Center where she worked in the 1990s to help establish two pioneering projects – the Strengthening Democratic Institutions Project with Graham Allison, who this month stepped down as the Center’s director, and the Preventive Defense Project with Ash Carter, the former Secretary of Defense who is the new Belfer Center director.

Cathryn Cluver Ashbrook, Executive Director of the Future of Diplomacy Project, discusses the importance of the final wording of the G-20 communique, particularly with respect to the climate change and energy policy dossiers, noting different approaches to achieve transatlantic compromise. She underlines the importance of high-level meetings such as the G-20 to address critical global challenges, including multilateral responses to North Korea’s provocations and the ongoing conflict in Syria.

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

With the fourth and final nuclear security summit approaching in March, the 2016 edition of the Nuclear Threat Initiative (NTI) Nuclear Security Index raises red flags about the international community’s implementation of the important measures needed to protect against catastrophic nuclear terrorism and to build an effective global nuclear security system. More importantly, it raises the question, how will leaders sustain momentum and high-level political attention on the need to secure dangerous nuclear materials once the summits come to an end?

Are nuclear sites secure?  There are some who might assume the answer is yes and that we should not worry about the possibility of nuclear bomb material being stolen. Yet, recent history has repeatedly demonstrated that high security facilities thought to be secure were actually vulnerable. Two such incidents last month illustrated this idea.

In thinking about how nuclear security and safeguards can fail, it is useful to keep in mind why security usually fails in general.  Most security managers and organizations have a good understanding of the assets they are trying to protect, the resources available to them to protect those assets, and the consequences should security fail (though this is sometimes greatly underestimated).  They often have a reasonably accurate understanding of the threats they face—who might attack, why, how, when, and with what goals and resources.  What is often lacking is a good understanding of the vulnerabilities—the weaknesses in the security that can be exploited by the threats—and how those vulnerabilities can be mitigated or eliminated.

Matthew Bunn, Will Tobey, Hui Zhang, and Nickolas Roth recently participated in a two-day roundtable discussion sponsored by the Stanley Foundation on U.S. nuclear security cooperation with Russia and China. The discussion, which involved experts from around the world, focused on overcoming challenges to nuclear security cooperation and ensuring that countries put in place effective and sustainable nuclear security measures with strong security culture.

The most significant achievement to emerge from the 2014 Nuclear Security Summit was a pledge by 35 countries to observe the terms of a joint agreement, known as Strengthening Nuclear Security Implementation. This document committed the signatories to incorporate the principles and guidelines of the International Atomic Energy Agency (IAEA) regarding nuclear security into their national laws, and to allow teams of international experts to periodically evaluate their security procedures. Promoted strongly by the chairs of all three nuclear summits—the United States, South Korea, and the Netherlands— the 2014 initiative is an important step towards creating a robust global security system designed to prevent nuclear materials from falling into the hands of terrorists.

Today, the United States and Japan announced that Japan would eliminate all the plutonium and highly-enriched uranium at its Fast Critical Assembly (FCA) at Tokai-mura.  This is a tremendous step forward for nuclear security; for terrorists, this would be some of the best material that exists in any non-nuclear-weapon state.  The material includes 331 kilograms of plutonium, most of it weapons-grade, and 214.5 kilograms of weapons-grade HEU.  (The FCA also includes over a ton of material just at the 20 percent U-235 mark that defines HEU.)   The weapons-grade HEU is enough for four simple terrorist “gun-type” bombs or a larger number of trickier-to-build implosion bombs.  The plutonium amounts to more than 40 bombs worth of material.

In the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.
