Nuclear Issues

The US withdrawal from the JCPOA has laid bare the strategic contradictions inherent in this approach. The United States has abrogated its leadership position on global nuclear non-proliferation while demanding trust and support from allies. It has also reopened the prospect of Iranian nuclear armament while forfeiting the moral and institutional ammunition the US would need to clinch a better deal.

Though the negotiation leading to the JCPOA took place over a significant stretch of time—indeed, it was built on the foundation of talks that began in 2003—it’s important to remember that the deal contains critical concessions regarding Iran’s production of plutonium, which the United States had been seeking from Tehran since the 1970s, when the two countries were allies.

Nuclear energy powerhouse Westinghouse Electric Co. filed for Chapter 11 bankruptcy on 29 March, with its parent company Toshiba writing off more than $6 billion in losses connected to its US businesses. Westinghouse was engaged in negotiations to build six AP1000 nuclear reactors in India as part of the landmark US-India civilian nuclear agreement. The bankruptcy filing raises fresh questions, not just about the fate of the reactors, but also about the future of the nuclear deal.

In a televised speech on January 1, Iranian President Hassan Rouhani said that Tehran had imported 200 metric tons of yellowcake uranium and would import another 120 tons at an unspecified future date. The imports are permitted by the nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), but nonetheless significantly exceed Iran’s needs for natural (that is, unenriched) uranium over the next 15 years. Iran’s import of such high levels of uranium suggests it may be stockpiling uranium to reach nuclear breakout before the deal’s initial limitations expire in 2031.

The JCPOA permits Iran to buy natural uranium to “replenish” its stocks as it sells enriched uranium on the international market. To date, Iran has had difficulties locating a buyer for its enriched uranium stocks – unsurprising, given the current excess of commercially available enriched uranium. This, however, has not stopped Iran from buying and stockpiling more yellowcake.

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.

Matthew Bunn, Professor of Practice at Harvard Kennedy School and Co-Principal Investigator at the Belfer Center’s Project on Managing the Atom, sits down with Aroop Mukharji (@aroopmukharji) to talk about everything nuclear—from the nuclear football to the best way to prevent nuclear smuggling.
