Nuclear Safety: NRC's Oversight of Fire Protection at U.S. Commercial Nuclear Reactor Units Could Be Strengthened
GAO-08-747: Published: Jun 30, 2008. Publicly Released: Jun 30, 2008.
After a 1975 fire at the Browns Ferry nuclear plant in Alabama threatened the unit's ability to shut down safely, the Nuclear Regulatory Commission (NRC) issued prescriptive fire safety rules for commercial nuclear units. However, nuclear units with different designs and different ages have had difficulty meeting these rules and have sought exemptions to them. In 2004, NRC began to encourage the n...
Nuclear Waste: DOE Lacks Critical Information Needed to Assess Its Tank Management Strategy at Hanford
GAO-08-793: Published: Jun 30, 2008. Publicly Released: Jun 30, 2008.
The Department of Energy (DOE) manages more than 56 million gallons of radioactive and hazardous waste stored in 149 single-shell and 28 double-shell underground tanks at its Hanford Site in Washington State. Many of these aging tanks have already leaked waste into the soil. Meanwhile, DOE's planned process for emptying the tanks and treating the waste--mixing it with molten glass and solidifying...
Department of Energy: Information on Its Management of Costs and Liabilities for Contractors' Pension and Postretirement Benefit Plans
GAO-08-642R: Published: Jun 19, 2008. Publicly Released: Jun 19, 2008.
For the past 60 years, the Department of Energy (DOE) and its predecessors have carried out their national security, environmental cleanup, and research and development missions through management and operating (M&O) contracts and other site contracts for operations at DOE-owned facilities. DOE currently has 43 such contracts with private companies and nonprofit organizations, including universiti...
Department of Energy: Office of Science Has Kept Majority of Projects within Budget and on Schedule, but Funding and Other Challenges May Grow
GAO-08-641: Published: May 30, 2008. Publicly Released: Jun 19, 2008.
The Department of Energy (DOE) has long suffered from contract and management oversight weaknesses. Since 1990 DOE contract management has been on GAO's list of programs at high risk for fraud, waste, abuse, and mismanagement. In 2003 DOE's Office of Science (Science) unveiled its 20-year plan to acquire and upgrade potentially costly research facilities. In light of DOE's history and the potentia...
Architect of the Capitol: Progress in Improving Energy Efficiency and Options for Decreasing Greenhouse Gas Emissions
GAO-08-917T: Published: Jun 18, 2008. Publicly Released: Jun 18, 2008.
In April 2007, GAO reported that 96 percent of the greenhouse gas emissions from the Capitol Hill Complex facilities--managed by the Architect of the Capitol (AOC)--resulted from electricity use throughout the complex and combustion of fossil fuels in the Capitol Power Plant. The report concluded that AOC and other legislative branch agencies could benefit from conducting energy audits to identify...
Oil and Gas Royalties: Litigation over Royalty Relief Could Cost the Federal Government Billions of Dollars
GAO-08-792R: Published: Jun 5, 2008. Publicly Released: Jun 5, 2008.
Oil and gas production from federal lands and waters is critical to meeting the nation's energy needs. This production provided about 31 percent of all oil and 29 percent of all natural gas produced in the United States in fiscal year 2007. Every five years, the federal government decides the areas in the offshore waters of the United States it will offer for leasing and establishes a schedule for...
Nuclear Weapons: NNSA Needs to Establish a Cost and Schedule Baseline for Manufacturing a Critical Nuclear Weapon Component
GAO-08-593: Published: May 23, 2008. Publicly Released: Jun 2, 2008.
The Department of Energy's National Nuclear Security Administration (NNSA) is responsible for manufacturing pits, a key component in a nuclear warhead. The department lost its ability to manufacture pits in 1989 with the closing of the Rocky Flats Plant. In 1996, the Los Alamos National Laboratory (LANL) was directed to reestablish a pit manufacturing capability, starting with a limited number of...
Global Nuclear Energy Partnership: DOE Should Reassess Its Approach to Designing and Building Spent Nuclear Fuel Recycling Facilities
GAO-08-483: Published: Apr 22, 2008. Publicly Released: May 22, 2008.
The Department of Energy (DOE) proposes under the Global Nuclear Energy Partnership (GNEP) to build facilities to begin recycling the nation's commercial spent nuclear fuel. GNEP's objectives include reducing radioactive waste disposed of in a geologic repository and mitigating the nuclear proliferation risks of existing recycling technologies. DOE originally planned a small engineering-scale demo...
Economic and Other Implications of Switching from Coal to Natural Gas at the Capitol Power Plant and at Electricity-Generating Units Nationwide
GAO-08-601R: Published: May 1, 2008. Publicly Released: May 1, 2008.
Elevated concentrations of greenhouse gases--carbon dioxide, methane, nitrous oxide, and several synthetic chemicals--in the atmosphere resulting from the combustion of fossil fuels and other sources have the potential to cause significant changes in the earth's climate. These potential impacts include shifts in sea level and weather patterns and could pose threats to coastal and other infrastruct...
Strategic Petroleum Reserve: Improving the Cost-Effectiveness of Filling the Reserve
GAO-08-726T: Published: Apr 24, 2008. Publicly Released: Apr 24, 2008.
The Strategic Petroleum Reserve (SPR) was created in 1975 to help protect the U.S. economy from oil supply disruptions and currently holds about 700 million barrels of crude oil. The Energy Policy Act of 2005 directed the Department of Energy (DOE) to increase the SPR storage capacity from 727 million barrels to 1 billion barrels, which it plans to accomplish by 2018. Since 1999, oil for the SPR h...
