Nuclear Issues

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.

Matthew Bunn, Professor of Practice at Harvard Kennedy School and Co-Principal Investigator at the Belfer Center’s Project on Managing the Atom, sits down with Aroop Mukharji (@aroopmukharji) to talk about everything nuclear—from the nuclear football to the best way to prevent nuclear smuggling.

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.

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.

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.

Like dozens of other world leaders, Chinese President Xi Jinping is preparing to attend the third Nuclear Security Summit, which will take place in The Hague on March 24 and 25.  China actively participated in the first two summits, and since the 9/11 terrorist attacks in 2001, China has indeed made strides in strengthening its system for protecting nuclear facilities.  To make sure that nuclear security systems are actually implemented effectively, however, the development of a strong security culture—in which the relevant individuals hold a deeply rooted belief that insider and outsider threats are credible—is imperative.

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.
