Nuclear Issues

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 the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.

In the dead of night on July 28, 2012, three senior citizens, including an 82-year-old Catholic nun, Sister Megan Rice, broke into the Y-12 National Security Complex near Oak Ridge, Tennessee, site of the US Highly Enriched Uranium Materials Facility (HEUMF). This self-proclaimed “Fort Knox of uranium” is America’s central repository for weapons-grade uranium.

....The security failings revealed by the nun and her fellow protesters are legion. The protesters were on the site for over an hour and 20 minutes, trekking about seven-tenths of a mile as the crow flies, but far longer as they traversed a steep ridge. They pierced fences equipped with sophisticated sensors. Yet the Y-12 Protective Force failed to spot them until they enjoyed unimpeded access to the exterior of the HEUMF forabout 20 minutes. Had these individuals been well-armed, well-equipped terrorists, instead of Bible-toting peace protesters, the incident would have been far more dire.

The 2011 “U.S. - Russia Joint Threat Assessment” offered both specific conclusions about the nature of the threat and general observations about how it might be addressed. This report builds on that foundation and analyzes the existing framework for action, cites gaps and deficiencies, and makes specific recommendations for improvement.

This chapter explores how nuclear security measures evolved in the United States, drawing lessons about the factors that lead states to improve their nuclear security approaches—a crucial question for today's efforts to convince states around the world to beef up nuclear security.
