RCED-99-188R: Published: May 19, 1999. Publicly Released: May 19, 1999.
Pursuant to a congressional request, GAO provided information on the differences between GAO's 1998 report on the Department of Energy's (DOE) Hanford Tank Waste Remediation project and a 1998 report on the same project prepared by the Pacific Rim Enterprise Center, focusing on why the two reports reached substantially different conclusions about the growth in costs for the tank waste project.GAO...
Nuclear Weapons: Design Reviews of DOE's Tritium Extraction Facility
RCED-98-75: Published: Mar 31, 1998. Publicly Released: Apr 30, 1998.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) plans to build a Tritium Extraction Facility at its Savannah River Site in South Carolina and the reports of three different teams responsible for reviewing the project's conceptual design and related products, focusing on: (1) the major comments raised by the three reviews; and (2) the process used by DOE to respon...
Department of Energy: National Priorities Needed for Meeting Environmental Agreements
RCED-95-1: Published: Mar 3, 1995. Publicly Released: Mar 3, 1995.
GAO reviewed the Department of Energy's (DOE) progress in cleaning up its nuclear weapons complex, focusing on: (1) its use of environmental agreements with state and federal regulators; and (2) the effectiveness of its cleanup strategy.GAO found that: (1) DOE has focused on collecting data and investigating sites, rather than the actual cleanup of sites; (2) DOE has only put a small amount of eff...
Nuclear Health and Safety: Consensus on Acceptable Radiation Risk to the Public Is Lacking
RCED-94-190: Published: Sep 19, 1994. Publicly Released: Oct 26, 1994.
Pursuant to a congressional request, GAO reviewed the consistency and compatibility of federal radiation standards, focusing on: (1) the various limits on public exposure to radiation; (2) the various protective strategies associated with the standards; and (3) whether the standards as a whole provide a coherent, complete federal framework for public radiation protection.GAO found that: (1) the di...
Energy Management: Payments in Lieu of Taxes for DOE Property May Need to Be Reassessed
RCED-94-204: Published: Jul 18, 1994. Publicly Released: Aug 17, 1994.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) compensation payments for property in lieu of state and local property taxes, focusing on: (1) how DOE identified communities for such payments and determined the payment amounts; (2) whether a 1987 revision of DOE payment policy was consistent with the Atomic Energy Act of 1954; and (3) the potential effect of DOE...

RCED-94-129: Published: Jun 7, 1994. Publicly Released: Jun 22, 1994.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) restructuring of its nuclear safety oversight functions, focusing on: (1) whether the proposed changes would improve DOE ability to ensure nuclear safety; (2) the process DOE used to consolidate the Nuclear Safety and Environment, Safety and Health (ES&H) Offices; and (3) issues that could affect ES&H nuclear safety...
Nuclear Security: Safeguards and Security Planning at DOE Facilities Incomplete
RCED-93-14: Published: Oct 30, 1992. Publicly Released: Jan 29, 1993.
Pursuant to a congressional request, GAO evaluated the Department of Energy's (DOE) planning process for safeguards and security at numerous sensitive facilities and sites, focusing on: (1) the extent to which DOE has completed safeguards and security plans for sensitive facilities; (2) the extent to which DOE has completed such plans for the areas, or sites, surrounding these facilities; and (3)...
Nuclear Waste: Hanford Single-Shell Tank Leaks Greater Than Estimated
RCED-91-177: Published: Aug 5, 1991. Publicly Released: Sep 19, 1991.
Pursuant to a congressional request, GAO determined whether the Department of Energy (DOE) or its Hanford, Washington, site contractor fully disclosed the volume of waste that leaked from the site's underground single-shell storage tanks.GAO found that: (1) DOE estimated that 750,000 gallons of liquid waste leaked from 66 shell tanks, but did not include the volume of cooling water that had been a...
Uranium Enrichment: DOE Needs to Pursue Alternative AVLIS Deployment Options
RCED-91-88: Published: Aug 8, 1991. Publicly Released: Aug 8, 1991.
GAO reviewed the Department of Energy's (DOE) demonstration and deployment of the atomic vapor laser isotope separation (AVLIS) program and the building of an AVLIS plant, focusing on technical, program, and economic issues.GAO found that: (1) independent experts believe that the AVLIS demonstration program will be successful, but the program will not provide the specific cost information needed f...
Nuclear Waste: Pretreatment Modifications at DOE Hanford's B Plant Should Be Stopped
