Nuclear Issues

The last seven decades without war among the great powers – what historians describe as “the long peace” – is a remarkable achievement. “This is a rare and unusual fact if you look at the last few thousand years of history,” said Graham Allison, director of the Belfer Center and moderator of the IDEASpHERE panel “Winning the Peace.” “Furthermore, it is no accident. Wise choices by statesmen have contributed to ‘the long peace,’ which has allowed many generations to live their lives.”

This paper studies under what conditions the U.S. can coerce its allies to forgo nuclear weapons. Specifically, why did Taiwan and South Korea give up their nuclear pursuits under American duress, while Israel and Pakistan attained a nuclear capability?

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 paper 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.

"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."

Researchers from the United States and Russia have issued a joint assessment of the global threat of nuclear terrorism, warning of a persistent danger that terrorists could obtain or make a nuclear device and use it with catastrophic consequences. The first joint threat assessment by experts from the world’s two major nuclear powers concludes: “If current approaches toward eliminating the threat are not replaced with a sense of urgency and resolve, the question will become not if but when, and on what scale, the first act of nuclear terrorism occurs.”

China's recent nuclear energy ambitions have put it in the forefront of research and development in the nuclear industry.This paper will first discuss the status of China's current spent fuel management methods and storage capability. Second, this paper will estimate and calculate the accumulated spent fuel and required spent fuel storage up to 2040 based on three different nuclear development scenarios. Third, future spent fuel management scenarios from now to 2040 are designed and financial costs and proliferation risks are evaluated and discussed associated with each scenario. Last, policy recommendations will be provided for the future spent fuel.

The Belfer Center hosted a half-day conference on March 23, 2017, gathering a group of top-level American and Japanese academics to discuss the US-Japan alliance and the rise of China. The event was well attended by scholars and students of Harvard and nearby universities, including a large group of scholars from the US Naval War College. Other notable attendees included policy officials as well as members of the Japanese Consulate in Boston.
