About this Dialogue
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is a landmark international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy and to further the goal of achieving nuclear disarmament and general and complete disarmament.
The NPT was opened for signature in 1968 and entered into force in 1970. Its membership includes 189 States Parties, making it the largest of any arms control Treaty in the world. The Treaty is underpinned by three "pillars"—nuclear non-proliferation, disarmament, and the peaceful use of nuclear energy—and is regarded as the legal and political cornerstone of the nuclear nonproliferation regime.
In this dialogue, John Dewes discusses the preparation and process involved in the removal of highly enriched uranium from research reactors and how the material is contained under appropriate controls.
