Background
The Briefing Book was first published in 1990 by Professor John Simpson and Ben Sanders under the auspices of the Mountbatten Centre for International Studies at the University of Southampton. In 2012, it found a new home in King’s College London and is currently produced in partnership with the James Martin Center for Non-Proliferation Studies.
The Briefing Books are divided into two parts. The first part contains an introduction to nuclear weapons and nuclear energy as well as a brief history of the NPT and significant milestones in the NPT Review Process. The second part includes documents related to the NPT review process including updates on relevant activities from the United Nations, International Atomic Energy Agency (IAEA), Conference on Disarmament and other multilateral arms control machinery as well as international developments relevant to the NPT review process.
