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
RCED-91-165: Published: Jun 12, 1991. Publicly Released: Jul 17, 1991.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) plans to modify its Hanford Site B Plant in Washington to pretreat mixed high-level radioactive waste before the vitrification process to turn it into glass.GAO found that: (1) although DOE was aware that the plant had not met specific federal or DOE regulations since 1987, it failed to timely discuss the compliance...
Nuclear Regulation: NRC's Relationship with the Institute of Nuclear Power Operations
RCED-91-122: Published: May 16, 1991. Publicly Released: Jun 17, 1991.
Pursuant to a congressional request, GAO reviewed the Nuclear Regulatory Commission's (NRC) relationship with the Institute of Nuclear Power Operations (INPO), focusing on whether NRC: (1) used INPO evaluation reports instead of its own oversight of the nuclear power industry; and (2) relied on INPO communications to alert industry of potential nuclear plant safety problems instead of issuing its...
Nuclear Waste: Delays in Addressing Environmental Requirements and New Safety Concerns Affect DOE's Waste Isolation Pilot Plant
T-RCED-91-67: Published: Jun 13, 1991. Publicly Released: Jun 13, 1991.
GAO discussed the status of the Department of Energy's (DOE) program for conducting transuranic (TRU) waste disposal tests at its Waste Isolation Pilot Plant (WIPP). GAO noted that: (1) DOE cannot use the WIPP repository until the facility meets environmental requirements and DOE resolves safety concerns; (2) from 1981 through 1988, DOE focused on building WIPP and failed to consider environmental...
Nuclear Waste: Problems and Delays With Characterizing Hanford's Single-Shell Tank Waste
RCED-91-118: Published: Apr 23, 1991. Publicly Released: May 30, 1991.
Pursuant to a congressional request, GAO reviewed the status of Department of Energy (DOE) efforts to characterize single-shell tank wastes at its Hanford, Washington site, focusing on impediments such as: (1) technological limitations; and (2) safety considerations.GAO found that: (1) due to the number of unresolved issues, DOE was unlikely to complete the first-phase characterization of the sing...
Nuclear Safety: The Defense Nuclear Facilities Safety Board's First Year of Operation
RCED-91-54: Published: Feb 5, 1991. Publicly Released: Apr 25, 1991.
Pursuant to a congressional request, GAO examined the accomplishments, operations, and problems faced by the Defense Nuclear Facilities Safety Board, focusing on: (1) the Board's mission to improve safety and health conditions at the Department of Energy's (DOE) defense nuclear facilities; (2) problems encountered in hiring technical staff; and (3) changes needed to enhance the Board's independenc...
Energy Reports and Testimony: 1990
RCED-91-84: Published: Jan 2, 1991. Publicly Released: Jan 2, 1991.
Growing dependence on imported oil, the need to develop new technologies to use energy cleanly and efficiently, and the tremendous problems at the Nation's nuclear weapons complex have all served to thrust the Department of Energy, and its programs, once again into the public spotlight. Because of these challenges, energy issues will continue to play a major role in economic and environmental publ...
Nuclear Regulation: NRC's Efforts to Ensure Effective Plant Maintenance Are Incomplete
RCED-91-36: Published: Dec 17, 1990. Publicly Released: Dec 21, 1990.
Pursuant to a congressional request, GAO examined the: (1) importance of safe nuclear power plant operations; and (2) status of the debate between the Nuclear Regulatory Commission (NRC) and the nuclear utility industry on the need for facility maintenance regulations.GAO found that: (1) while both NRC and the industry agreed that maintenance was crucial to safe, reliable, and efficient power plan...
