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...
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...
Uranium Enrichment: Extension of Decontamination and Decommissioning Fund May Be Needed to Cover Projected Cleanup Costs
GAO-08-277T: Published: Nov 15, 2007. Publicly Released: Nov 15, 2007.
Cleaning up the nation's three uranium enrichment plants will cost billions of dollars and could span decades. These plants--located near Oak Ridge, Tenn.; Paducah, Ky.; and Portsmouth, Ohio--are contaminated with radioactive and hazardous materials. In 1992, the Energy Policy Act created the Uranium Enrichment Decontamination and Decommissioning Fund (Fund) to pay for plant cleanup. Fund revenues...
Fusion Energy: Definitive Cost Estimates for U.S. Contributions to an International Experimental Reactor and Better Coordinated DOE Research Are Needed
GAO-08-30: Published: Oct 26, 2007. Publicly Released: Oct 26, 2007.
The United States is pursuing two paths to fusion energy--magnetic and inertial. On November 21, 2006, the United States signed an agreement with five countries and the European Union to build and operate the International Thermonuclear Experimental Reactor (ITER) in Cadarache, France, to demonstrate the feasibility of magnetic fusion energy. The United States also built and operates facilities to...
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: Plans for Addressing Most Buried Transuranic Wastes Are Not Final, and Preliminary Cost Estimates Will Likely Increase
GAO-07-761: Published: Jun 22, 2007. Publicly Released: Jun 22, 2007.
Since the 1940s, the development of nuclear weapons technologies has generated transuranic wastes--materials contaminated by certain man-made radioactive elements. These wastes can remain dangerous for thousands of years. Until 1970, the Department of Energy's (DOE) predecessors buried these wastes in shallow pits and trenches. Today, state officials and communities near DOE's major disposal sites...
The Department of Energy: Key Steps Needed to Help Ensure the Success of the New Loan Guarantee Program for Innovative Technologies by Better Managing Its Financial Risk
GAO-07-339R: Published: Feb 28, 2007. Publicly Released: Feb 28, 2007.
In May 2006, the Department of Energy (DOE) proposed transferring appropriations from some DOE accounts to begin a new loan guarantee program (LGP) authorized by the Energy Policy Act of 2005 (EPAct 05). Title XVII of EPAct 05--Incentives for Innovative Technologies--authorized the LGP to guarantee loans for projects intended to (1) decrease air pollutants or man-made greenhouse gases by reducing...
