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...
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...

RCED-99-243: Published: Aug 6, 1999. Publicly Released: Aug 6, 1999.
Pursuant to a congressional request, GAO provided information on the Nuclear Regulatory Commission's (NRC) participation in the International Nuclear Regulators Association, focusing on: (1) the Association's activities since it was created; (2) U.S. costs to support NRC's participation in the Association; (3) the views of NRC's commissioners and others on the benefits of the Association; and (4)...
Uranium Enrichment: Process to Privatize the U.S. Enrichment Corporation Needs to Be Strengthened
RCED-95-245: Published: Sep 14, 1995. Publicly Released: Sep 14, 1995.
Pursuant to a legislative requirement, GAO provided information on the proposed privatization of the U.S. Enrichment Corporation (USEC), focusing on: (1) the net present value of the corporation; and (2) whether the privatization plan would result in any ongoing obligation or undue cost to the government.GAO found that: (1) the USEC privatization plan predicts that USEC stock could sell for up to...
Nuclear Nonproliferation: Information on Nuclear Exports Controlled by U.S.-EURATOM Agreement
RCED-95-168: Published: Jun 16, 1995. Publicly Released: Jul 6, 1995.
Pursuant to a congressional request, GAO provided information on the United States-European Atomic Energy Community (EURATOM) agreement, focusing on the: (1) amount of U.S. nuclear exports to EURATOM and Japan and U.S.-origin nuclear materials transferred from Japan to EURATOM; (2) value of U.S. nuclear exports to EURATOM and Japan; and (3) nuclear industry's views on the potential impact on nucle...
Nuclear Regulation: Slow Progress in Identifying and Cleaning Up NRC's Licensees' Contaminated Sites
RCED-95-95: Published: Apr 24, 1995. Publicly Released: May 9, 1995.
Pursuant to a congressional request, GAO reviewed the effectiveness of the Nuclear Regulatory Commission's (NRC) decommissioning program, focusing on: (1) NRC progress in identifying all former licensees' sites that require additional cleanup; (2) NRC progress in ensuring that sites on its Site Decommissioning Management Plan (SDMP) are cleaned up in a timely manner; and (3) factors that impede th...
Uranium Enrichment: Observations on the Privatization of the United States Enrichment Corporation
T-RCED-95-116: Published: Feb 24, 1995. Publicly Released: Feb 24, 1995.
GAO discussed the privatization of the U.S. Enrichment Corporation (USEC). GAO noted that: (1) the Energy Policy Act requires it to evaluate the USEC privatization plan before implementation and to report to Congress on whether the plan would result in any ongoing government obligations or undue costs and whether the expected sale revenues would meet or exceed USEC net present value; (2) its deter...
Uranium Enrichment: Activities Leading to Establishment of the U.S. Enrichment Corporation
RCED-94-227FS: Published: Jun 27, 1994. Publicly Released: Jul 27, 1994.
Pursuant to a congressional request, GAO reviewed the transition of the Department of Energy's (DOE) Uranium Enrichment Program to the United States Enrichment Corporation.GAO found that: (1) despite a short transition period and a small transition team, the Corporation was successfully established on July 1, 1993; (2) DOE effectively completed the lease agreements, developed regulatory oversight...
Nuclear Nonproliferation: Concerns With U.S. Delays in Accepting Foreign Research Reactors' Spent Fuel
RCED-94-119: Published: Mar 25, 1994. Publicly Released: Apr 25, 1994.
GAO provided information on U.S. efforts to convert foreign research reactors from highly enriched uranium (HEU) to low enriched uranium (LEU) and to consolidate spent fuel, focusing on the: (1) effects of delays in renewing the Off-Site Fuels Policy on U.S. nonproliferation goals and programs; (2) Department of Energy's (DOE) efforts to renew the fuels policy; and (3) price to be charged to forei...
