Nuclear Issues

Characterizing the future performance of energy technologies can improve the development of energy policies that have net benefits under a broad set of future conditions. In particular, decisions about public investments in research, development, and demonstration (RD&D) that promote technological change can benefit from (1) an explicit consideration of the uncertainty inherent in the innovation process and (2) a systematic evaluation of the tradeoffs in investment allocations across different technologies. To shed light on these questions, over the past five years several groups in the United States and Europe have conducted expert elicitations and modeled the resulting societal benefits. In this paper, the authors discuss the lessons learned from the design and implementation of these initiatives.

Many Chinese worry that as Japanese politics moves rightward, it could result in the country seeking its own weapons. Beijing's concerns have intensified with its confrontation with the Abe administration over historical recognition and territorial issues. In this op-ed, Hui Zhang argues that it is time for Tokyo to stop reprocessing and eliminate its surplus plutonium as soon as possible. Tokyo should address concerns over its reprocessing plans and plutonium stocks. To reduce suspicions, Tokyo should take specific steps to abide strictly by its "no surplus plutonium policy".

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.

Each year, the Science, Technology, and Public Policy (STPP) Program at the Belfer Center for Science and International Affairs at the Harvard Kennedy School welcomes new pre- and post-doctoral fellows and visiting researchers to a select team of scholars exploring the critical role that science and technology play in everyday life.

"The military buildup by China, its Asia-Pacific neighbors and the United States is creating a classical security dilemma that is increasing the potential for military conflict in the region. Although history is replete with conflicts between existing and rising powers, conflict between China and the United States is not preordained. Opportunities exist in both the diplomatic and military arenas for both countries to actively engage the other in open and direct communication to increase transparency, reduce tensions, and improve understanding. It is in the best interest of the United States, China and countries around the world to confront the reality that is a rising nuclear-armed China and, in doing so, manage its accession into the regional and world order without conflict."

"The conventional wisdom among those who looked at the Middle East used to be that you had a choice either of supporting the autocrat or being stuck with the religious extremists. The extraordinary diffusion of information created in Egypt and other Middle Eastern countries reveals a strong middle that we weren't fully aware of. What is more, new technologies allow this new middle to coordinate in ways unseen before Twitter, Facebook, and so forth, and this could lead to a very different politics of the Middle East. This introduces a new complexity to our government's dealings with the region."
