Nuclear Issues

In mid-July, as an attempted coup was taking place in Turkey, many in the United States wondered whether U.S. tactical nuclear weapons stored at the Turkish airbase, Incirlik, were adequately protected against theft. Congressional Research Service Nuclear Weapons Policy Specialist, Amy Woolf, recently published a short article describing some of the security systems surrounding those weapons.

Matthew Bunn and Gary Samore just published an op-ed arguing that the program to build a factory that converts excess plutonium from dismantled nuclear weapons into plutonium-uranium mixed oxide fuel for nuclear reactors has become too expensive. Although the two helped to launch the program in the mid-90s, they argue "It is time to stop throwing good money after bad and pursue cheaper alternatives that will serve our national security better" and "whatever we do with this plutonium in the long term, we should move to put it under international monitoring, and commit never again to use it in weapons..." You can read their complete argument here.

Last week, a National Academies of Sciences, Engineering, and Medicine panel affirmed the goal of eliminating highly enriched uranium (HEU) from civilian use, while recommending step-wise conversion of high performance research reactors using weapon-grade uranium fuel and that the White House coordinate a 50-year national roadmap for neutron-based research. (Full disclosure:  I sat on that committee, and oversaw the NNSA reactor conversion program from 2006-9; this post, however, represents my views, not necessarily those of the committee or NNSA.)

In 1998, in Operation Auburn Endeavor, the U.S. government helped fly 4.3 kilograms of highly enriched uranium (HEU) and low-enriched uranium (LEU) from vulnerable facilities in war-torn Georgia to the Dounreay reprocessing plant in the United Kingdom. At the time, those in the U.S. government involved in the project, myself included, thought that was all the HEU there was in Georgia. So it was a surprise when the IAEA announced the removal of another 1.83 kilograms of HEU from Georgia – apparently now really the last of the HEU there.

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.

On April 28, the Project on Managing the Atom joined the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey, The Netherlands government, and the United Nations Office for Disarmament Affairs (UNODA) in convening nuclear nonproliferation experts from around the world at the United Nations to participate in a Symposium on the 2015 Nonproliferation Treaty (NPT) Review Conference.

"Speaking from the White House earlier this month, President Obama announced details of a framework agreement between Iran and the P5+1—the United States, Russia, China, France, the United Kingdom, and Germany—that limits Iran’s path to building a nuclear weapon over the next 10 to 15 years. Although negotiators will finalize technical details between now and the June 30 deadline, the parameters provide Iran with sanctions relief in exchange for limits on its uranium enrichment, converting its Arak heavy water reactor, limiting the number and type of centrifuges, and agreeing to intrusive inspections. Should Iran cheat or fail to uphold its end of the bargain, however, the United States and its allies reserve the right to “snap-back” into place tough economic and financial sanctions..."
