Following the news that the Trump administration plans to abandon the Intermediate-Range Nuclear Forces (INF) Treaty, signed in 1987 by Ronald Reagan and Mikhail Gorbachev, ten Belfer Center nuclear and U.S.-Russia relations experts offered their thoughts on the significance and consequences of this action.
 

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.

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.

China’s approach to strengthening the security of its nuclear weapons, materials, and facilities plays an important role in facilitating strong global action on nuclear security. This report provides a better understanding of Chinese perceptions of the threat of nuclear terrorism and attitudes toward the nuclear security challenge; describes the current status of nuclear security practices in China and of planned improvements in rules and organization, management, and technologies; and recommends steps for further improvements.

There has been much speculation as to what might replace the Nuclear Security Summits after 2016. One candidate touted as a suitable inheritor of the summits’ mantle is the International Atomic Energy Agency. In this discussion paper, Trevor Findlay examines whether and to what extent the IAEA could and should do so, what form its role might take, and how the Agency and summiteers might prepare for such an eventuality.

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.

In the dead of night on July 28, 2012, three senior citizens, including an 82-year-old Catholic nun, Sister Megan Rice, broke into the Y-12 National Security Complex near Oak Ridge, Tennessee, site of the US Highly Enriched Uranium Materials Facility (HEUMF). This self-proclaimed “Fort Knox of uranium” is America’s central repository for weapons-grade uranium.

....The security failings revealed by the nun and her fellow protesters are legion. The protesters were on the site for over an hour and 20 minutes, trekking about seven-tenths of a mile as the crow flies, but far longer as they traversed a steep ridge. They pierced fences equipped with sophisticated sensors. Yet the Y-12 Protective Force failed to spot them until they enjoyed unimpeded access to the exterior of the HEUMF forabout 20 minutes. Had these individuals been well-armed, well-equipped terrorists, instead of Bible-toting peace protesters, the incident would have been far more dire.

The 2011 “U.S. - Russia Joint Threat Assessment” offered both specific conclusions about the nature of the threat and general observations about how it might be addressed. This report builds on that foundation and analyzes the existing framework for action, cites gaps and deficiencies, and makes specific recommendations for improvement.

The Belfer Center’s Eben Harrell and Pulitzer Prize-winning author David E. Hoffman for the first time report the details of one of the largest nuclear security operations of the post-Cold War years — a  secret 17-year, $150 million operation to secure plutonium in the tunnels of Degelen Mountain.

This chapter explores how nuclear security measures evolved in the United States, drawing lessons about the factors that lead states to improve their nuclear security approaches—a crucial question for today's efforts to convince states around the world to beef up nuclear security.
