Hosted by Carnegie's Nuclear Policy Program

The Nuclear Non-Proliferation Treaty does not define the term “nuclear weapon” or identify the evidence that would determine whether a state is seeking to manufacture or acquire nuclear weapons. For six years, the Carnegie Endowment for International Peace has been developing an analytic framework for demarcating activities and programs that are exclusively nuclear-weapons-related from others, in accordance with NPT obligations. This approach—a nuclear firewall—utilizes pertinent indicators relating to materials, equipment, activities, and contextual factors that delineate peaceful from nuclear weapons activities. Carnegie’s aim with the firewall concept is to enable greater confidence in civil nuclear technology cooperation; to provide timely warning of proliferation concerns in order to facilitate diplomacy; to indicate steps states could take to reassure others about the peaceful nature of a program; and, relatedly, to provide a detailed template for nuclear disarmament. At this session, Carnegie will release a paper on the nuclear firewall concept, and experts will discuss its potential contribution to the implementation of all three pillars of the NPT.
