To minimize – and ultimately eliminate – the use of highly enriched uranium (HEU) in civilian and naval applications
NTI published two groundbreaking reports on HEU minimization and the establishment of regional HEU-free zones
Highly enriched uranium (HEU), a core component of a nuclear weapon, has also been used for decades to power research reactors, produce medical isotopes and fuel naval submarines. Today, with a few exceptions, technical developments have made it possible to replace HEU with LEU in nearly all current uses and have rendered future new civil uses of HEU obsolete.
NTI supports the phased elimination of civil uses for HEU and is working to build an international consensus on the importance of reducing dependence on HEU for peaceful activities. In particular, NTI has supported and expanded programs in the United States to convert research reactors using HEU to low-enriched uranium (LEU) and to remove HEU from as many sites and countries as possible.
A series of current and past NTI activities have sought to achieve these goals:
Over a ten-year period, more than 700 kilograms of highly enriched uranium was removed from Poland, making it the 31st country to completely remove their HEU.
The Civilian HEU Reduction and Elimination Resource Collection has been updated by CNS in the wake of the April 2016 Nuclear Security Summit (NSS).
Report draws from input of study group of former military and political officials from nuclear-armed states.
A new paper published by NTI, the Center for Nonproliferation Studies and the Fissile Materials Working Group calls for the establishment of regional zones free of highly enriched uranium (HEU) in advance of the 2016 Nuclear Security Summit.
A new paper published by NTI, the Center for Nonproliferation Studies and the Fissile Materials Working Group offers timely recommendations for action that countries can pursue ahead of the 2016 Nuclear Security Summit.
A new paper develops a market-based roadmap for Russia to transition from HEU to LEU in the production of Molybdenum-99, an area ripe for a Russian commitment at the 2014 Nuclear Security Summit.
A new CNS issue brief by Anya Loukianova discusses U.S. and international efforts to balance the trade-offs between ensuring medical isotope supply and reducing HEU in medical isotope production.
NTI's Corey Hinderstein and Andrew Newman call for a change in the conversation on highly enriched uranium (HEU) from minimization to elimination.
The proceedings revealed a robust and growing consensus on the principle, underscoring the responsiblity of all stakeholders to make commitments their irreversible.
