Nuclear Risks in the 21st Century

by CSIS Center for Strategic and International Studies

This course material is only available in the iTunes U app on iPhone or iPad.

Course Description

Despite the end of the Cold War and the arms reductions that followed, there are roughly 15,000 nuclear weapons across 9 states and materials to make many more spread around the world.  Many countries use nuclear technologies for energy, medical applications, and even to enhance food security – extending the dangers beyond the weapons-possessing states.

This course provides reports, events, and multimedia tools produced by the CSIS Proliferation Prevention Program that seek to examine some of the major nuclear risks of the 21st century - beyond just the nuclear weapons themselves- and ways these risks could be mitigated.  Major topics include the possibility of switching from Highly Enriched Uranium (HEU), a nuclear weapons-building block, to safer Low Enriched Uranium (LEU) for naval fuel; the growing stockpile of separated plutonium, also a key ingredient for nuclear weapons, in Northeast Asia; and the level of transparency some countries have offered into their nuclear stockpiles.  More content will be added throughout 2017 and 2018, so subscribe to stay abreast of the latest.
