Nuclear Waste: Improvements Needed in Monitoring Contaminants in Hanford Soils
RCED-92-149: Published: Jul 6, 1992. Publicly Released: Aug 26, 1992.
Pursuant to a congressional request, GAO examined the Department of Energy's (DOE) programs to monitor and characterize contamination in the vadose zone, the unsaturated soil above the groundwater table, at the DOE Hanford site, focusing on: (1) how effective existing DOE vadose zone programs have been; (2) how successful DOE has been developing a strategy for improving its programs; and (3) wheth...
Energy Reports and Testimony: 1991
RCED-92-120: Published: Jul 13, 1992. Publicly Released: Jul 13, 1992.
This annual index includes information on these and other U.S. General Accounting Office (GAO) documents directly related to energy that were issued between January and December 1991. This index should be useful for general information and research purposes and for understanding energy issues that GAO is addressing...
Nuclear Waste: Questionable Uses of Program Funds at Lawrence Livermore Laboratory
RCED-92-157: Published: May 28, 1992. Publicly Released: Jun 29, 1992.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) Lawrence Livermore National Laboratory's use of nuclear waste funds to support independent research projects and to manage project activities for the Yucca Mountain, Nevada, underground repository site for permanent disposal of radioactive wastes.GAO found that: (1) in fiscal year (FY) 1990 and FY 1991, Livermore us...
Nuclear Waste: Development of Casks for Transporting Spent Fuel Needs Modification
RCED-92-56: Published: Mar 13, 1992. Publicly Released: Apr 1, 1992.
Pursuant to a congressional request, GAO reviewed Department of Energy (DOE) efforts to implement transportation-related activities under the Nuclear Waste Policy Amendments Act of 1987, which requires DOE to investigate Yucca Mountain, Nevada, as a potential site for the permanent disposal of nuclear waste in an underground repository and to construct a repository at the site if it finds that the...
Connecticut Low-Level Waste
RCED-92-137R: Published: Mar 17, 1992. Publicly Released: Mar 17, 1992.
Pursuant to a congressional request, GAO provided information on states' efforts to implement the Low-Level Radioactive Waste Policy Amendments Act of 1985, focusing on Connecticut's program for developing a disposal facility for commercial low-level radioactive waste. GAO noted that: (1) 13 states, including 8 states that are members of state compacts, plan to develop new disposal facilities; (2)...
Nuclear Health and Safety: Problems Continue for Rocky Flats Solar Pond Cleanup Program
RCED-92-18: Published: Oct 17, 1991. Publicly Released: Nov 26, 1991.
Pursuant to a congressional request, GAO provided updated information on the Department of Energy's (DOE) progress in cleaning up solar evaporation ponds at its Rocky Flats Nuclear Weapons Plant, focusing on the: (1) estimated cost of the project; (2) status of the detailed plans for conducting and monitoring the program; (3) status of clean-up activities; and (4) specific milestones that DOE has...
Nuclear Waste: Operation of Monitored Retrievable Storage Facility Is Unlikely by 1998
RCED-91-194: Published: Sep 24, 1991. Publicly Released: Oct 30, 1991.
Pursuant to a congressional request, GAO reviewed the alternatives of storing spent nuclear fuel exclusively at utility reactor sites or transferring the waste to a federal facility for monitored retrievable storage (MRS), focusing on the: (1) likelihood of an MRS facility operating by 1998; (2) legal implications if the Department of Energy (DOE) is unable to take delivery of wastes in 1998; (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...
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.
