Abstract:
Highly enriched uranium (HEU) is the simplest nuclear material to use for an improvised nuclear device, making it a target for terrorist groups seeking to inflict mass destruction. This paper examines the current status of HEU in naval propulsion programs worldwide, with a specific focus on the U.S. Navy’s program. It includes a technical assessment of less risky low-enriched uranium (LEU) alternatives and recommendations to enable conversion to such alternate technologies.

Abstract:
Permanent Risk Reduction of Radioactive Sources Illustration by Evelyn Helminen, MIIS There has been a marked increase in international and domestic attention to the need to replace high-risk radioactive sources with less risky and non-isotopic alternatives in order to forestall an act of radiological terrorism. In response to this need, the James Martin Center for Nonproliferation Studies at the Middlebury Institute for International Studies at Monterey, with the support of the US and UK governments, hosted three, closed-door workshops with governmental and nongovernmental experts in Washington, London, and Vienna to propose appropriate policies. Through these workshops and additional research, CNS has developed the new occasional paper, “Permanent Risk Reduction: A Roadmap for Replacing High-Risk Radioactive Sources and Materials,” which offers a series of actions that governments could take to help expedite and encourage the substitution of high-risk sources with non-isotopic alternatives as an important contribution to the nuclear security framework.
