Nuclear Material: Agencies Have Sound Procedures for Managing Exchanges but Could Improve Inventory Monitoring
GAO-16-713: Published: Sep 23, 2016. Publicly Released: Oct 24, 2016.
In the United States, from October 1, 2003, through November 30, 2015, there were 817 exchanges of nuclear material that carried obligations to foreign partners under nuclear cooperation agreements. These exchanges allowed the obligated nuclear material to be transferred between U.S. facilities without physically moving it. For example, if a facility had a certain amount of obligated nuclear mater...
Iran Nuclear Agreement: The International Atomic Energy Agency's Authorities, Resources, and Challenges
GAO-16-565: Published: Jun 9, 2016. Publicly Released: Jul 14, 2016.
As outlined in the Joint Comprehensive Plan of Action (JCPOA), the International Atomic Energy Agency (IAEA) was asked to verify and monitor Iran's implementation of a range of nuclear-related commitments. IAEA is using its safeguards authorities and conducting additional activities agreed to by Iran under the JCPOA to do so. Iran's commitments include limits on uranium enrichment levels and on en...
Nuclear Nonproliferation: Preliminary Observations on IAEA's Role in Verifying the Iran Agreement
GAO-16-417: Published: Feb 12, 2016. Publicly Released: Feb 23, 2016.
As outlined in the JCPOA, IAEA was asked to verify Iran's implementation of a range of nuclear-related commitments, and IAEA uses its authorities and conducts additional verification activities to do so, according to IAEA. Iran's commitments include limits on uranium enrichment levels and enriched uranium inventories. GAO's preliminary observations indicate that IAEA plans to verify Iran's impleme...
Department of Energy: Management of Excess Uranium
GAO-15-475T: Published: Apr 22, 2015. Publicly Released: Apr 22, 2015.
GAO has identified four key issues related to the Department of Energy's (DOE) management of excess uranium and uranium transfers in reports, testimonies, and a legal opinion issued since 2006 as follows:Elimination of a guideline to limit DOE's annual uranium sales and transfers. In May 2014, GAO found DOE's decision to discontinue its 10 percent guideline for limiting uranium sales and transfers...
Nuclear Weapons: Some Actions Have Been Taken to Address Challenges with the Uranium Processing Facility Design
GAO-15-126: Published: Oct 10, 2014. Publicly Released: Oct 10, 2014.
In January 2013, the National Nuclear Security Administration (NNSA) completed a review to identify the factors that contributed to the space/fit issue with the Uranium Processing Facility (UPF), and identified a number of factors within both NNSA and the contractor managing the UPF design at that time. NNSA's review identified shortcomings in 1) federal oversight of the project, 2) design integra...
Department of Energy: Enhanced Transparency Could Clarify Costs, Market Impact, Risk, and Legal Authority to Conduct Future Uranium Transactions
GAO-14-291: Published: May 9, 2014. Publicly Released: Jun 9, 2014.
The Department of Energy (DOE) undertook four uranium transactions involving USEC Inc. (USEC) in 2012 and 2013. These transactions served to provide the company with operating cash. According to DOE, the department benefited from these transactions in two ways: (1) by ensuring availability of domestic low-enriched uranium (LEU) for the production of tritium, a key radioactive isotope used to enhan...
Nuclear Weapons: Factors Leading to Cost Increases with the Uranium Processing Facility
GAO-13-686R: Published: Jul 12, 2013. Publicly Released: Jul 12, 2013.
In summary, GAO found the following:Overly optimistic National Nuclear Security Administration (NNSA) assumptions about the Uranium Processing Facility (UPF) contained in multiple cost estimates prepared from 2004 to 2011 (upper bound of cost range was approximately $1.1 billion and $6.5 billion, respectively) are the primary factors that contributed to its cost increase. Initial NNSA UPF cost est...
Nuclear Material: DOE's Depleted Uranium Tails Could Be a Source of Revenue for the Government
GAO-11-752T: Published: Jun 13, 2011. Publicly Released: Jun 13, 2011.
Since the 1940s, the Department of Energy (DOE) has been processing natural uranium into enriched uranium, which has a higher concentration of the isotope uranium-235 that can be used in nuclear weapons or reactors. This has resulted in over 700,000 metric tons of leftover depleted uranium, also known as "tails," that have varying residual concentrations of uranium-235. The tails are stored at DOE...
Nuclear Weapons: National Nuclear Security Administration's Plans for Its Uranium Processing Facility Should Better Reflect Funding Estimates and Technology Readiness
GAO-11-103: Published: Nov 19, 2010. Publicly Released: Nov 19, 2010.
Built in the 1940s and 1950s, the Y-12 National Security Complex, located in Oak Ridge, Tennessee, is the National Nuclear Security Administration's (NNSA) primary site for enriched uranium activities. Because Y-12 facilities are outdated and deteriorating, NNSA is building a more modern facility--known as the Uranium Processing Facility (UPF). NNSA estimates that the UPF will cost up to $3.5 bill...
Nuclear Material: Several Potential Options for Dealing with DOE's Depleted Uranium Tails Could Benefit the Government
GAO-08-613T: Published: Apr 3, 2008. Publicly Released: Apr 3, 2008.
Since the 1940s, the Department of Energy (DOE) has been processing natural uranium into enriched uranium, which has a higher concentration of the isotope uranium-235 that can be used in nuclear weapons or reactors. This has resulted in over 700,000 metric tons of leftover depleted uranium, also known as "tails," that have varying residual concentrations uranium-235. The tails are stored at DOE's...
