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...
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 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...
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...
NRC's Oversight of Licensees' Decommissioning Practices Can Be Improved
T-RCED-89-57: Published: Aug 3, 1989. Publicly Released: Aug 3, 1989.
GAO discussed the Nuclear Regulatory Commission's (NRC) decommissioning requirements for obsolete nuclear facilities, focusing on nuclear fuel facility licenses. GAO found that: (1) NRC requires owners of obsolete nuclear facilities to remove the facilities safely from service and reduce residual radioactivity to allow unrestricted property use; (2) the Environmental Protection Agency (EPA) will n...
Nuclear Regulation: NRC's Decommissioning Cost Estimates Appear Low
RCED-88-184: Published: Jul 29, 1988. Publicly Released: Sep 19, 1988.
In response to a congressional request, GAO discussed the: (1) adequacy of the Nuclear Regulatory Commission's (NRC) cost estimates for decommissioning nuclear power plants and fuel-cycle facilities; and (2) methods that utilities and operators could use to ensure the availability of decommissioning funds.GAO found that: (1) the NRC cost estimates were low because they did not consider the costs o...
Nuclear Waste: Unresolved Issues Concerning Hanford's Waste Management Practices
RCED-87-30: Published: Nov 4, 1986. Publicly Released: Nov 18, 1986.
In response to a congressional request, GAO reviewed the Department of Energy's (DOE) management and disposal of defense nuclear waste at its Hanford, Washington, facility to determine how Hanford complies with the Resource Conservation and Recovery Act of 1976 (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA).RCRA regulates hazardous waste from...
Nuclear Energy: Environmental Issues at DOE's Nuclear Defense Facilities
RCED-86-192: Published: Sep 8, 1986. Publicly Released: Sep 25, 1986.
Pursuant to a congressional request, GAO: (1) identified key environmental issues at nine Department of Energy (DOE) nuclear defense facilities; and (2) evaluated the status of DOE efforts to strengthen its environmental, safety, and health oversight programs.GAO found that: (1) eight facilities have groundwater contaminated with radioactive or hazardous substances at levels higher than the propos...
