Nuclear disarmament, nuclear nonproliferation, and the threat of nuclear terrorism are among the most critical challenges facing the world today. In a major new book, Unmaking the Bomb, a group of physicists and experts on nuclear security from Princeton University’s Program on Science and Global Security and the International Panel on Fissile Materials propose a fresh approach to addressing these long-held nuclear challenges.

Rather than tackling these issues separately, the authors argue that all three must be understood and realized together with renewed focus on the production, stockpiling, and disposal of plutonium and highly enriched uranium.

Carnegie hosted two of the book’s authors to explain the scale and nature of the fissile materials challenge and outline proposed policies aimed at reducing and eventually ending the dangers these materials pose. These include ending the production of highly enriched uranium and plutonium for weapons, as well as their use as military and civilian reactor fuels, and the verified elimination of all national stockpiles.
