South Africa, the only nation ever to build a nuclear arsenal and voluntarily dismantle it, proudly regards itself as a champion of disarmament and nonproliferation. But for almost two decades, the United States and South Africa have struggled over the handling of highly enriched uranium (HEU) stockpiles that have remained after the closure of its bomb program. What is the dispute over South Africa’s stocks of HEU, and how is it playing out? What are its roots? And what are the consequences for global security?

At a meeting on April 6 at the Carnegie Endowment’s offices in Washington, D.C., the Center for Public Integrity’s Douglas Birch and R. Jeffrey Smith will explain how the two countries have interacted under presidents Obama and Zuma. Harvard University’s Matthew Bunn will discuss South Africa’s HEU in the context of efforts to improve nuclear security around the globe. Former ambassador Thomas Wheeler of South Africa will join by video from Johannesburg to offer his views on the subject. Carnegie’s Togzhan Kassenova, an associate in Carnegie’s nuclear policy program, will moderate.

The meeting is open to the public, but advance registration is requested here.
