Evolving threats posed by nuclear weapons include existing Cold War arsenals, as well as efforts by states and non-state actors to acquire nuclear weapons. At the same time, an outmoded system of nuclear governance must confront the risks of nuclear energy in a post-Fukushima world. The ability of the United States and Russia to further reduce their nuclear weapons, plus related efforts to prevent the global spread of nuclear material, remain key challenges. New thinking is also needed about the regulation of nuclear activity. Nuclear Security aims to:   

·        Further reduce the role and size of global nuclear arsenals.

·        Prevent and limit nuclear proliferation, with emphases on North Korea and Iran.

·        Address security risks and safety concerns regarding nuclear energy.

·        Strengthen norms, regulations, and institutions overseeing nuclear activity.

·        Advance capacities of junior and mid-career nuclear security specialists.
