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 Nonproliferation: More Progress Needed in Implementing Recommendations for IAEA's Technical Cooperation Program
GAO-11-482T: Published: Mar 17, 2011. Publicly Released: Mar 17, 2011.
A key mission of the International Atomic Energy Agency (IAEA) is promoting the peaceful uses of nuclear energy through its Technical Cooperation (TC) program, which provides equipment, training, fellowships, and other services to its member states. The United States provides approximately 25 percent of the TC program's annual budget. While the vast majority of TC projects have not involved the tr...
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 Because Y-12 facilities are outdated and deteriorating, NNSA is building a more modern facility--known as the Uranium Processing Facility (UPF).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 Safety: Convention on Nuclear Safety Survey (GAO-10-550SP, April 2010), an E-supplement to GAO-10-489
GAO-10-550SP: Published: Apr 29, 2010. Publicly Released: Jun 1, 2010.
This document is an E-supplement to GAO-10-489. It presents the results of GAOs survey of the contracting parties to the Convention on Nuclear Safety. This survey was a key component of GAO's effort to gather information about the perceived effectiveness of the Convention in improving nuclear safety worldwide. The objectives of this survey were to determine which aspects of the Convention are work...
Nuclear Weapons: Actions Needed to Address Scientific and Technical Challenges and Management Weaknesses at the National Ignition Facility
GAO-10-488: Published: Apr 8, 2010. Publicly Released: Apr 8, 2010.
In March 2009, the National Nuclear Security Administration (NNSA), a separately organized agency within the Department of Energy, completed construction of the National Ignition Facility (NIF). NNSA considers NIF critical to its stockpile stewardship program to ensure the safety and reliability of the nation's nuclear weapons, absent live nuclear testing. NIF is intended to simulate the extreme t...
Global Nuclear Energy Partnership: DOE Should Reassess Its Approach to Designing and Building Spent Nuclear Fuel Recycling Facilities
GAO-08-483: Published: Apr 22, 2008. Publicly Released: May 22, 2008.
The Department of Energy (DOE) proposes under the Global Nuclear Energy Partnership (GNEP) to build facilities to begin recycling the nation's commercial spent nuclear fuel. GNEP's objectives include reducing radioactive waste disposed of in a geologic repository and mitigating the nuclear proliferation risks of existing recycling technologies. DOE originally planned a small engineering-scale demo...
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...
Nuclear Material: DOE Has Several Potential Options for Dealing with Depleted Uranium Tails, Each of Which Could Benefit the Government
GAO-08-606R: Published: Mar 31, 2008. Publicly Released: Apr 2, 2008.
Since the 1940s, one mission of the Department of Energy (DOE) and its predecessor agencies has been processing uranium as a source of nuclear material for defense and commercial purposes. A key step in this process is the enrichment of natural uranium, which increases its concentration of uranium-235, the isotope of uranium that undergoes fission to release enormous amounts of energy. Before it c...
Advanced Energy Technologies: Budget Trends and Challenges for DOE's Energy R&D Program
GAO-08-556T: Published: Mar 5, 2008. Publicly Released: Mar 5, 2008.
For decades, the nation has benefited from relatively inexpensive energy, in the process growing heavily reliant on conventional fossil fuels--oil, natural gas, and coal. However, in the current wake of higher energy costs and environmental concerns about fossil fuel emissions, renewed attention is turning to the development of advanced energy technologies as alternatives. In the United States, th...
Uranium Enrichment: Extension of Decontamination and Decommissioning Fund May Be Needed to Cover Projected Cleanup Costs
GAO-08-277T: Published: Nov 15, 2007. Publicly Released: Nov 15, 2007.
Cleaning up the nation's three uranium enrichment plants will cost billions of dollars and could span decades. These plants--located near Oak Ridge, Tenn.; Paducah, Ky.; and Portsmouth, Ohio--are contaminated with radioactive and hazardous materials. In 1992, the Energy Policy Act created the Uranium Enrichment Decontamination and Decommissioning Fund (Fund) to pay for plant cleanup. Fund revenues...
