Progress & Gaps

Nuclear security around the world has improved substantially over the last twenty years, yet there remains much to be done in securing nuclear weapons and weapons-usable materials, nuclear facilities, and radiological sources. The following reports provide insights on what progress has already been made, and what work remains to be done. These documents are drawn from Harvard Kennedy School’s Belfer Center for Science and International Affairs, as well as from other leading scholars and organizations working on issues of nuclear security and nuclear terrorism.

Advancing Nuclear Security: Evaluating Progress and Setting New Goals
March 2014 | Report
Harvard Kennedy School | Belfer Center for Science and International Affairs
By Matthew Bunn, Martin B. Malin, Nickolas Roth, and William H. Tobey

"In the lead-up to the nuclear security summit in The Hague, 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 authors conclude that “all countries with nuclear weapons, separated plutonium, or highly enriched uranium (HEU) on their soil have more to do to ensure these items are effectively and lastingly secured.”  (click here to view)

Threat Perceptions and Drivers of Change in Nuclear Security Around the World: Results of a Survey
March 2014 | Report
Harvard Kennedy School | Belfer Center for Science and International Affairs
By Matthew Bunn and Eben Harrell 

Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years. This goal implied that many countries would change their nuclear security policies. But the factors that drive changes in nuclear security policies, and that constrain those changes, are not well understood. We conducted a survey of selected nuclear security experts in countries with nuclear weapons, highly enriched uranium (HEU), or separated plutonium, to explore this issue. This paper describes the survey, its results, and implications for next steps to strengthen global nuclear security. (click here to view)

Beyond Nuclear Summitry: The Role of the IAEA in Nuclear Security Diplomacy After 2016
March 2013 | Discussion Paper
Harvard Kennedy School | Belfer Center for Science and International Affairs
By Trevor Findlay

Since it became apparent that the nuclear security summits are likely to end with a final meeting in Washington DC in 2016 there has been much speculation―but little detailed analysis―as to what might replace them. One candidate touted as a suitable inheritor of the summits’ mantle is the International Atomic Energy Agency (IAEA). This discussion paper examines whether and how the IAEA could and should do so, what form its role might take, and how the Agency and the summiteers might prepare for such an eventuality.

Consolidation: Thwarting Nuclear Theft
March 2012 | Report
Harvard Kennedy School | Belfer Center for Science and International Affairs
By Matthew Bunn and Eben Harrell

This paper (a) discusses how to set priorities among different stocks to be consolidated; (b) describes the scope and progress of existing consolidation efforts; and (c) suggests steps to complement and extend the existing programs. Our discussion of the next steps for consolidation will fall into two categories: covering additional stocks and facilities that are not yet effectively addressed, and using additional policy approaches to strengthen the effort. On the next page, table ES-1 summarizes our recommendations. (click here to view)

Securing China's Weapons-Usable Nuclear Material
February 2014 | Journal Article
Science and Global Security
By Hui Zhang

"This article describes the status of China’s military and civilian nuclear programs, fissile material production and associated nuclear facilities, and the Chinese nuclear experts and officials’ perspectives on the nuclear terrorism threat. It gives details of China’s nuclear security practices, attitudes, and regulations, as well as identifying areas of concern. The article recommends ways to strengthen China’s nuclear material protection, control, and accounting systems and suggests opportunities for increased international cooperation."

The Four-Year Effort: Contributions of the Global Threat Reduction Initiative to Secure the World's Most Vulnerable Nuclear Material
December 2013 | Report
National Nuclear Security Administration | Global Threat Reduction Initiative

"As President Obama’s Four-Year Effort comes to a close this month, NNSA is highlighting the work carried out by its nonproliferation programs to reduce the threat of vulnerable nuclear material around the world. In support of the Four-Year Effort, NNSA’s Global Threat Reduction Initiative (GTRI) led the effort to secure and, when possible, eliminate these dangerous materials." (click here to view)

What Types of Nuclear Material Require What Levels of Security?
February 2014 | Presentation
Harvard Kennedy School | Belfer Center for Science and International Affairs
By Matthew Bunn

In this presentation to an Institute for Nuclear Materiials Management workshop on risk-informing security, Matthew Bunn proposes a new approach to judging which materials would be easiest or more difficult for terrorists to use in a nuclear bomb, and hence which materials require more or less security.

"The 2014 Nuclear Threat Initiative (NTI) Nuclear Materials Security Index is the second edition of a first-of-its-kind public assessment of nuclear materials security conditions around the world. Developed with the Economist Intelligence Unit (EIU), the NTI Index was created (a) to assess the security of weapons-usable nuclear materials around the world and (b) to encourage governments to take actions and provide assurances about the security of the world’s deadliest materials."

The Nuclear Security Summit: Progress Report
March 2012 | Report
Arms Control Association
By Michelle Cann, Kelsey Davenport and Sarah Williams

"This report seeks to provide a comprehensive overview of the progress states have made to improve nuclear security over the course of the NSS process, drawing specific attention to actions taken since the Seoul summit. It uses the progress reports submitted by participating states at the 2012 summit, statements made to the International Atomic Energy Agency (IAEA) General Conference, IAEA Nuclear Security Reports, government press releases, and media reports to identify actions countries have taken in support of the summits’ goals. This approach aims to provide a complete record of achievements, but inconsistencies in how and what states report complicate efforts to evaluate progress using open sources." (click here to view)
