Nuclear Issues

"This week’s Nuclear Security Summit in The Hague was understandably overshadowed by the continuing international response to Russia’s illegal annexation of Crimea. One aspect of the Ukraine crisis that deserves more attention is how the current standoff will impact the future of nuclear security cooperation between the United States and Russia..."

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.

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.

HKS Professor of Practice Matthew Bunn presented this presentation at the Plutonium Disposition Alternatives Workshop for the Union of Concerned Scientists in Washington, DC on January 30-31, 2014.

Matthew Bunn and Will Tobey spoke with Piet de Klerk, the Dutch Sherpa organizing the 2014 Nuclear Security Summit, on October 7 at a United Nations event sponsored by the Dutch mission to the UN. In these slides, Bunn and Tobey provide an updated summary of the threat of nuclear terrorism and recommendations for next steps to reduce the threat, based in part on the new U.S.-Russian report, Steps to Prevent Nuclear Terrorism.

Despite substantial progress in improving nuclear security in recent years, there is more to be done.  The threats of nuclear theft and terrorism remain very real. This presentation recommends learning from the much stronger national and international efforts in nuclear safety, and in particular, taking steps to build international understanding of the threat; establish effective performance objectives; assure performance; train and certify needed personnel; build security culture and exchange best practices; reduce the number of sites that need to be protected; and strengthen the international framework and continue the dialogue once leaders are no longer meeting regularly at the summit level. Matthew Bunn presented this talk, based on a recent paper, on July 3rd, 2013 at the International Conference on Nuclear Security in Vienna.

This chapter summarizes the case that it is plausible that sophisticated terrorist groups could make a nuclear bomb if they got the nuclear material; that some terrorist groups have actively tried to get nuclear bombs in the past, and some groups are likely to try again in the future; and that unless urgent action is taken to improve nuclear security, it is plausible that terrorists might be able to get the potential nuclear bomb material they would need.

The United States and Russia possess 95% of the world’s nuclear weapons and most of the world’s weapons-usable nuclear material, and so bear a special responsibility for preventing nuclear terrorism. Unfortunately, both countries missed an opportunity in Seoul – neither committed to major new steps to strengthen nuclear security at home beyond the steps they were already taking, nor did they announced any new joint initiatives. That must change.

On the eve of the Nuclear Security Summit in Seoul, South Korea, a new study finds that an international initiative to secure all vulnerable nuclear stockpiles within four years has reduced the dangers they pose.
