Vehicle Fuel Economy: Reforming Fuel Economy Standards Could Help Reduce Oil Consumption by Cars and Light Trucks, and Other Options Could Complement These Standards
GAO-07-921: Published: Aug 2, 2007. Publicly Released: Aug 2, 2007.
Concerns over national security, environmental stresses, and high fuel prices have raised interest in reducing oil consumption. Through the Corporate Average Fuel Economy (CAFE) program, the National Highway Traffic Safety Administration (NHTSA) requires cars and light trucks to meet certain fuel economy standards. As requested, GAO discusses (1) how CAFE standards are designed to reduce fuel cons...
Nuclear Safety: Construction of the Protective Shelter for the Chernobyl Nuclear Reactor Faces Schedule Delays, Potential Cost Increases, and Technical Uncertainties
GAO-07-923: Published: Jul 19, 2007. Publicly Released: Jul 26, 2007.
In 1986, an explosion at the Chernobyl nuclear power plant in Ukraine destroyed the reactor building and released massive amounts of radioactive contamination. A temporary shelter was built over the damaged reactor to prevent further contamination. The United States is a major donor to an international project to build a new shelter to replace the existing one, which is badly deteriorating. GAO wa...
Nuclear Waste: DOE Should Reassess Whether the Bulk Vitrification Demonstration Project at Its Hanford Site Is Still Needed to Treat Radioactive Waste
GAO-07-762: Published: Jun 12, 2007. Publicly Released: Jun 12, 2007.
The Department of Energy (DOE) is demonstrating a technology called bulk vitrification, in parallel with the Hanford waste treatment plant, to treat a portion of the radioactive waste stored in 177 tanks at its Hanford site in southeastern Washington state. DOE faces technical and management problems that have affected the original objectives to justify demonstrating the bulk vitrification technol...
Nuclear Nonproliferation: Progress Made in Improving Security at Russian Nuclear Sites, but the Long-term Sustainability of U.S.-Funded Security Upgrades Is Uncertain
GAO-07-404: Published: Feb 28, 2007. Publicly Released: Apr 2, 2007.
Safeguarding nuclear warheads and materials that can be used to make nuclear weapons is a primary national security concern of the United States. Since 1993, the Departments of Energy (DOE) and Defense (DOD) have worked to improve security at sites housing weapons-usable nuclear material and warheads in Russia and other countries. In 1995, DOE established the Materials Protection, Control, and Acc...
Department of Energy: Major Construction Projects Need a Consistent Approach for Assessing Technology Readiness to Help Avoid Cost Increases and Delays
GAO-07-336: Published: Mar 27, 2007. Publicly Released: Mar 27, 2007.
The Department of Energy (DOE) spends billions of dollars on major construction projects that help maintain the nuclear weapons stockpile, conduct research and development, and process nuclear waste so that it can be disposed of. Because of DOE's long-standing project management problems, GAO determined the extent to which (1) DOE's major construction projects are having cost increases and schedul...
Nuclear Nonproliferation: DOE's International Radiological Threat Reduction Program Needs to Focus Future Efforts on Securing the Highest Priority Radiological Sources
GAO-07-282: Published: Jan 31, 2007. Publicly Released: Mar 13, 2007.
Following the terrorist attacks of September 11, 2001, U.S. and international experts raised concerns that unsecured radiological sources were vulnerable to theft and posed a significant security threat to the United States and the international community. Radioactive material is encapsulated or sealed in metal to prevent its dispersal and is commonly called a sealed radiological source. Sealed ra...
Nuclear Nonproliferation: Focusing on the Highest Priority Radiological Sources Could Improve DOE's Efforts to Secure Sources in Foreign Countries
GAO-07-580T: Published: Mar 13, 2007. Publicly Released: Mar 13, 2007.
Following the terrorist attacks of September 11, 2001, U.S. and international experts raised concerns that unsecured radiological sources posed a significant security threat to the United States and the international community. If certain types of these sources were obtained by terrorists, they could be used to produce a radiological dispersion device, or dirty bomb. In response, the Department of...
Nuclear Waste: DOE's Efforts to Protect the Columbia River from Contamination Could Be Further Strengthened
GAO-06-1018: Published: Aug 28, 2006. Publicly Released: Sep 5, 2006.
The Department of Energy's (DOE) Hanford site in Washington State is one of the most contaminated nuclear waste sites in North America. The Columbia River flows through about 50 miles of the site. Radioactive and hazardous contamination from decades of producing nuclear materials for the nation's defense have migrated through the soil into the groundwater, which generally flows toward the river. I...
Gas Pipeline Safety: Views on Proposed Legislation to Reauthorize Pipeline Safety Provisions
GAO-06-1027T: Published: Aug 4, 2006. Publicly Released: Aug 4, 2006.
The Pipeline Safety Improvement Act of 2002 established a risk-based program for gas transmission pipelines--termed integrity management--which requires pipeline operators to identify areas where the consequences of a pipeline incident would be the greatest, such as highly populated areas. Operators must assess pipelines in these areas for safety threats (such as corrosion), repair or replace defe...
Yucca Mountain: DOE's Planned Nuclear Waste Repository Faces Quality Assurance and Management Challenges
GAO-06-550T: Published: Apr 25, 2006. Publicly Released: Apr 25, 2006.
The Department of Energy (DOE) is working to obtain a license from the Nuclear Regulatory Commission (NRC) to construct a nuclear waste repository at Yucca Mountain in Nevada. The project, which began in the 1980s, has been beset by delays. In 2004, GAO raised concerns that persistent quality assurance problems could further delay the project. Then, in 2005, DOE announced discovery of employee e-m...
