Nuclear Issues

A sampling of articles in the Spring 2016 issue of the Belfer Center's journal International Security.

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

Based on satellite imagery, Chinese publications, and discussions with Chinese experts, This report suggests that China has much more civilian enrichment capacity than previously thought, and even more is on the way. If these new estimates are correct, China has enough enrichment capacity to meet its nuclear power fuel requirements for the coming decade and beyond. Further, China will have excess enrichment capacity and will likely become a net exporter of commercial enrichment services.

Some observers believe that plutonium reprocessing is on the verge of an expansion, while others argue that the end of the practice is in sight. The risk of nuclear proliferation has always been the chief objection to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons...

In this oped for the Bulletin of the Atomic Scientists, Hui Zhang contributes a third article to an international roundtable on reprocessing:

Hui Zhang presented "China’s Nuclear Modernization and Disarmament" at The Prague Agenda 2014,  Prague, Czech Republic, December 4-5, 2014.

Hui Zhang presented "Enhancing Nuclear Security Culture in China" at The 14th PIIC Beijing Seminar on International Security:Strategic Stability and Cooperation, Hangzhou, China, October 19-22, 2014.

The ninth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will be held at the UN Headquarters in New York from April 27-May 22, 2015. This is the fourth such conference since the indefinite extension of the NPT in 1995. Participating governments will discuss nuclear disarmament, non-proliferation, and the peaceful use of nuclear energy with a view to arriving at consensus on a number of issues.

Hui Zhang presented "Strengthening China-U.S. Cooperation on Nuclear Security" at the U.S.-China Nonproliferation and Nuclear Security Dialogue in Washington, D.C., June 26–27, 2014.

The most significant achievement to emerge from the 2014 Nuclear Security Summit was a pledge by 35 countries to observe the terms of a joint agreement, known as Strengthening Nuclear Security Implementation. Promoted strongly by the chairs of all three nuclear summits—the United States, South Korea, and the Netherlands— the 2014 initiative is an important step towards creating a robust global security system designed to prevent nuclear materials from falling into the hands of terrorists. Yet China, along with Russia, India, and Pakistan, did not join the pledge. Beijing has not offered any explanations. China not only can join the new initiative, it should join it—because joining is in China’s own national interest.
