Managing Critical Isotopes: Stewardship of Lithium-7 Is Needed to Ensure a Stable Supply
GAO-13-716: Published: Sep 19, 2013. Publicly Released: Oct 17, 2013.
Little is known about lithium-7 production in China and Russia and whether their supplies can meet future domestic demand. According to industry representatives, China and Russia produce enough lithium-7 to meet demand from U.S. pressurized water reactors, a type of commercial nuclear power reactor that requires lithium-7 for safe operation. However, China's continued supply may be reduced by its...
Nuclear Nonproliferation: National Nuclear Security Administration Has Improved the Security of Reactors in its Global Research Reactor Program, but Action Is Needed to Address Remaining Concerns
GAO-09-949: Published: Sep 17, 2009. Publicly Released: Sep 17, 2009.
Worldwide, about 165 research reactors use highly enriched uranium (HEU) fuel. Because HEU can also be used in nuclear weapons, the National Nuclear Security Administration (NNSA) established the Global Research Reactor Security (GRRS) program to make security upgrades at foreign research reactors whose security did not meet guidelines established by the International Atomic Energy Agency (IAEA)....
Fusion Energy: Definitive Cost Estimates for U.S. Contributions to an International Experimental Reactor and Better Coordinated DOE Research Are Needed
GAO-08-30: Published: Oct 26, 2007. Publicly Released: Oct 26, 2007.
The United States is pursuing two paths to fusion energy--magnetic and inertial. On November 21, 2006, the United States signed an agreement with five countries and the European Union to build and operate the International Thermonuclear Experimental Reactor (ITER) in Cadarache, France, to demonstrate the feasibility of magnetic fusion energy. The United States also built and operates facilities to...
Fusion Research: Costs of Ending DOE's Participation in the International Thermonuclear Experimental Reactor Project Appear Reasonable
RCED-99-140R: Published: Apr 30, 1999. Publicly Released: Jun 2, 1999.
Pursuant to a congressional request, GAO determined whether the Department of Energy's (DOE) expenses to close out its participation in the International Thermonuclear Experimental Reactor (ITER) project were reasonable.GAO noted that: (1) DOE's plans for an orderly closeout of its ITER activities appear reasonable; (2) in addition to the $12.2 million appropriation provided by Congress, DOE also...
Department of Energy: Major System Acquisitions From 1980 Through 1996
RCED-97-85R: Published: Mar 4, 1997. Publicly Released: Mar 4, 1997.
Pursuant to a congressional request, GAO provided a listing of the major systems acquisitions (MSA) that were conducted by the Department of Energy (DOE) between 1980 and 1996.GAO noted that: (1) DOE has spent tens of billions of dollars on projects over the past decade and a half, many of which experienced significant cost overruns and delays, and some have never been completed; (2) these activit...
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...
Nuclear Science: Monitoring Improved, but More Planning Needed for DOE Test and Research Reactors
RCED-92-123: Published: Jul 15, 1992. Publicly Released: Aug 17, 1992.
Pursuant to a congressional request, GAO provided information on the Department of Energy's (DOE) nondefense-related nuclear facilities, focusing on: (1) DOE management and long-range planning for replacement of potentially dangerous and aging reactors; and (2) the safety and operating condition of research reactor facilities.GAO found that: (1) DOE has no plans for the retirement or replacement o...
Nuclear Science: DOE's Self-Supporting Isotope Program Is Experiencing Problems
RCED-92-122FS: Published: Jun 3, 1992. Publicly Released: Jul 20, 1992.
Pursuant to a congressional request, GAO examined the status of the Department of Energy's (DOE) Isotope Production and Distribution Program, focusing on: (1) problems the program has experienced in operating on a self-supporting basis; (2) the cost factors affecting DOE isotope production; and (3) domestic isotope customers' reactions to the program.GAO found that: (1) DOE has experienced difficu...
Uranium Enrichment: GAO's Views on DOE's New Laser Enrichment Technology--AVLIS
T-RCED-91-23: Published: Apr 10, 1991. Publicly Released: Apr 10, 1991.
GAO discussed the Department of Energy's (DOE) program to develop the atomic vapor laser isotope separation process (AVLIS), a new uranium enrichment technology, focusing on issues that DOE needed to address before building an AVLIS plant. GAO noted that, before building an AVLIS plant, DOE should: (1) adequately demonstrate the AVLIS process with full-scale equipment and develop convincing cost p...
Nuclear Weapons Complex: GAO's Views on DOE's Reconfiguration Study
T-RCED-91-19: Published: Mar 13, 1991. Publicly Released: Mar 13, 1991.
GAO discussed the Department of Energy's (DOE) January 1991 Nuclear Weapons Complex Reconfiguration Study. GAO noted that the study: (1) was only the first step in developing a more detailed plan, which would include an environmental impact statement on reconfiguring the complex; (2) recommended a smaller complex in the future, but did not clearly specify what the complex would look like in 2015;...
