New American assured fuel supply would promote peaceful use of nuclear power while strengthening nuclear nonproliferation
WASHINGTON, D.C. – As part of the Obama Administration’s commitment to strengthen global nuclear nonproliferation efforts, the U.S. Department of Energy (DOE) and the National Nuclear Security Administration (NNSA) today announced the availability of a reserve stockpile of low-enriched uranium (LEU) for use as commercial nuclear power fuel. The stockpile was derived from down-blending surplus highly enriched uranium (HEU) from the U.S. stockpile.
This new American Assured Fuel Supply (AFS) creates a vehicle for promoting the peaceful use of nuclear energy without exacerbating nuclear proliferation risks. Through this plan, the U.S. is able to encourage wider use of nuclear power production at the same time as it meets U.S. nuclear disarmament obligations.
The AFS sets aside LEU down-blended from surplus U.S. weapons HEU to serve as a backup fuel supply for foreign or domestic reactors in the event of a supply disruption. Along with the International Fuel Bank to be administered by the International Atomic Energy Agency (IAEA), the AFS gives nation states that are looking to nuclear power as a clean energy source an assured supply of LEU, decreasing the need to develop costly enrichment technology. Establishing this reserve will put confidence in the U.S. as a reliable supplier of nuclear fuel and should encourage other governments to see American nuclear vendors as preferable partners.
“As more countries look to nuclear power as a low-carbon option for addressing growing energy demands, assuring a fuel supply without promoting proliferation sensitive technologies is a critical national security priority,” said Secretary of Energy Steven Chu. “In addition to protecting fuel supplies for commercial power producers, the Assured Fuel Supply helps demonstrate our commitment to nuclear nonproliferation by eliminating surplus weapons uranium in a way that promotes the peaceful use of nuclear energy.”
In 2005, the Department of Energy announced that the U.S. would set aside 17.4 metric tons of surplus HEU to be blended-down to LEU and held in reserve to deal with disruptions in the nuclear fuel supply. The down-blending of the 17.4 metric tons of surplus HEU is scheduled for completion in 2012. When complete, it will result in approximately 290 metric tons of LEU, of which approximately 230 metric tons will form the reserve. The remainder of the LEU is being used to pay for the down-blending and processing costs. This will leave the AFS with approximately six reloads for an average 1,000 MW reactor.
The AFS reserve is modest in size and designed not to disrupt or replace market mechanisms. Rather, it is to be sold at market value in the event of demonstrated need after all other market options are exhausted.
DOE published an announcement of the availability of the AFS today in the Federal Register. The AFS will be available through U.S. persons to both domestic and foreign recipients. The Secretary of Energy will approve any AFS sale and have the authority to prioritize requests.
The NNSA’s Office of Nonproliferation and International Security will chair an AFS Committee that will be responsible for assessing eligibility of applicants and making a recommendation to the Secretary on the sale of LEU from the AFS. This Committee will include representatives from several different DOE offices, including DOE’s Office of Nuclear Energy, DOE’s Office of Environmental Management, and the DOE and NNSA Offices of General Counsel.

Established by Congress in 2000, NNSA is a semi-autonomous agency within the U.S. Department of Energy responsible for enhancing national security through the military application of nuclear science in the nation’s national security enterprise. NNSA maintains and enhances the safety, security, reliability, and performance of the U.S. nuclear weapons stockpile without nuclear testing; reduces the global danger from weapons of mass destruction; provides the U.S. Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the U.S. and abroad.
