Highly enriched uranium (HEU)—one of the key ingredients for nuclear weapons—is one of the most dangerous materials on the planet and is spread across dozens of countries.
Since 1992, the international community has taken important steps to reduce the risk posed by HEU—removing and eliminating thousands of kilograms of HEU, converting HEU-fueled reactors to use low-enriched uranium (LEU), and promoting the adoption of LEU alternatives for medical isotope production. Despite significant progress, the work to reduce—and ultimately eliminate—HEU is far from finished.
Today, there are approximately 61 metric tons of civilian HEU spread across more than 100 facilities in 25 countries. HEU is also used in reactors on certain naval vessels in India, Russia, the United Kingdom and the United States. Approximately 290 metric tons of HEU remain in global naval inventories—enough material for thousands of nuclear weapons.
A Roadmap to Minimize and Eliminate Highly Enriched Uranium, a new paper from NTI, the Center for Nonproliferation Studies and the Fissile Materials Working Group, lays out a roadmap with five pathways to ending civilian HEU use and beginning the necessary research and development to minimize and ultimately eliminate HEU for naval use. It includes specific recommendations that countries can undertake prior to the 2016 Nuclear Security Summit.
According to the report, "Countries should view HEU elimination as a form of permanent threat reduction and as an essential component of the global effort to combat the threat of nuclear terrorism."
