Dispositioning military plutonium to promote nuclear non-proliferation

Abstract

Given that all chemical varieties of plutonium can be used in nuclear weapons, sophisticated measures are required to disposition it so that its potential to contribute to horizontal and vertical nuclear proliferation is minimised. This article argues that the present options for dispositioning military plutonium are not acceptable, and, as a result, this plutonium should be placed in international storage until an acceptable method is found. First, a brief description of plutonium and its use is given. A discussion follows on non-proliferation and feasibility criteria by which the policy options to disposition military plutonium should be assessed. Then several policy options are outlined and assessed against the specified criteria. Finally, the concept of international plutonium storage is described.
