Former Deputy Secretary of Energy Elizabeth Sherwood-Randall is joining Harvard Kennedy School’s Belfer Center for Science and International Affairs as a Senior Fellow, the Center announced today. Sherwood-Randall, who has served in the White House and Departments of Energy and Defense, is returning to the Center where she worked in the 1990s to help establish two pioneering projects – the Strengthening Democratic Institutions Project with Graham Allison, who this month stepped down as the Center’s director, and the Preventive Defense Project with Ash Carter, the former Secretary of Defense who is the new Belfer Center director.

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.

Matthew Bunn and Martin B. Malin examine the conditions needed for nuclear energy to grow on a scale large enough for it to be a significant part of the world’s response to climate change. They consider the safety, security, nonproliferation, and waste management risks associated with such growth and recommend approaches to managing these risks. Bunn and Malin argue that although technological solutions may contribute to nuclear expansion in the coming decades, in the near term, creating the conditions for large-scale nuclear energy growth will require major international institutional innovation.

Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years, but the factors that drive and/or constrain nuclear security changes are not well understood. Matthew Bunn and Eben Harrell surveyed nuclear security professionals in countries with nuclear weapons, HEU, or separated plutonium to explore this issue. This paper describes the survey, its results, and implications for strengthening global nuclear security.
