Nuclear Issues

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

During the Future of Diplomacy Project's 2017 'Europe Week' series, diplomats, scholars, and policymakers visited the Kennedy School to examine Europe's greatest challenges. 

Putin and his government seek respect, stability from next U.S. administration, panel says.

The Project on Managing the Atom offers fellowships for pre-doctoral, post-doctoral, and mid-career researchers for one year, with a possibility for renewal, in the stimulating environment of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. The online application for 2016-2017 fellowships opened December 15, 2015, and the application deadline is January 15, 2016. Recommendation letters are due by February 1, 2016.

As the policy community prepares to assess an agreement between the U.S. and its P5+1 partners and Iran, Senate Foreign Relations Committee Chairman Bob Corker asked me to review the history of analogous agreements for lessons that illuminate the current challenge. In response to his assignment, I reviewed the seven decades of the nuclear era, during which the U.S. negotiated arms-control treaties, including the Non-Proliferation Treaty of 1968; strategic arms limitation talks and agreements from SALT to New Start; the North Korean accord of 1994; the agreements that helped eliminate nuclear weapons in Ukraine, Kazakhstan, and Belarus in the early 1990s; and the pact that eliminated the Libyan nuclear weapons program in 2003.

Among many lessons and clues from this instructive history, five stand out

Iran’s top nuclear negotiator was heading back to Tehran on Sunday to consult with his nation’s leadership, as negotiators remained divided over how to limit and monitor Tehran’s nuclear program and even on how to interpret the preliminary agreement they reached two months ago.

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

"One of the dramas playing out this month in New York at the 2015 Review Conference for parties to the Treaty on the Non-proliferation of Nuclear Weapons (NPT) concerns the future of discussions on establishing the weapons of mass destruction free zone in the Middle East..."

China will triple the number of nuclear power plants it has in operation by 2020 according to official plans, and the country’s nuclear fleet will increase 20-fold by 2050 under some not-yet-approved proposals. But how and where will China get the uranium to fuel them all? Will China need to resort to breeder reactors and reprocessing, with all the proliferation problems they incur? Or is there another way? In this journal article for the Bulletin of the Atomic Scientists, Hui Zhang suggests that between China’s domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, China could meet even the most ambitious target, thus avoiding the troublesome and dangerous path of reprocessing.
