Nuclear Safety: Convention on Nuclear Safety Survey (GAO-10-550SP, April 2010), an E-supplement to GAO-10-489
GAO-10-550SP: Published: Apr 29, 2010. Publicly Released: Jun 1, 2010.
This document is an E-supplement to GAO-10-489. It presents the results of GAOs survey of the contracting parties to the Convention on Nuclear Safety. This survey was a key component of GAO's effort to gather information about the perceived effectiveness of the Convention in improving nuclear safety worldwide. The objectives of this survey were to determine which aspects of the Convention are work...
Nuclear Weapons: Actions Needed to Address Scientific and Technical Challenges and Management Weaknesses at the National Ignition Facility
GAO-10-488: Published: Apr 8, 2010. Publicly Released: Apr 8, 2010.
In March 2009, the National Nuclear Security Administration (NNSA), a separately organized agency within the Department of Energy, completed construction of the National Ignition Facility (NIF). NNSA considers NIF critical to its stockpile stewardship program to ensure the safety and reliability of the nation's nuclear weapons, absent live nuclear testing. NIF is intended to simulate the extreme t...
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...
Nuclear Material: Several Potential Options for Dealing with DOE's Depleted Uranium Tails Could Benefit the Government
GAO-08-613T: Published: Apr 3, 2008. Publicly Released: Apr 3, 2008.
Since the 1940s, the Department of Energy (DOE) has been processing natural uranium into enriched uranium, which has a higher concentration of the isotope uranium-235 that can be used in nuclear weapons or reactors. This has resulted in over 700,000 metric tons of leftover depleted uranium, also known as "tails," that have varying residual concentrations uranium-235. The tails are stored at DOE's...
Nuclear Material: DOE Has Several Potential Options for Dealing with Depleted Uranium Tails, Each of Which Could Benefit the Government
GAO-08-606R: Published: Mar 31, 2008. Publicly Released: Apr 2, 2008.
Since the 1940s, one mission of the Department of Energy (DOE) and its predecessor agencies has been processing uranium as a source of nuclear material for defense and commercial purposes. A key step in this process is the enrichment of natural uranium, which increases its concentration of uranium-235, the isotope of uranium that undergoes fission to release enormous amounts of energy. Before it c...
Advanced Energy Technologies: Budget Trends and Challenges for DOE's Energy R&D Program
GAO-08-556T: Published: Mar 5, 2008. Publicly Released: Mar 5, 2008.
For decades, the nation has benefited from relatively inexpensive energy, in the process growing heavily reliant on conventional fossil fuels--oil, natural gas, and coal. However, in the current wake of higher energy costs and environmental concerns about fossil fuel emissions, renewed attention is turning to the development of advanced energy technologies as alternatives. In the United States, th...
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...
Federal Electricity Subsidies: Information on Research Funding, Tax Expenditures, and Other Activities That Support Electricity Production
GAO-08-102: Published: Oct 26, 2007. Publicly Released: Oct 26, 2007.
Electricity is vital to our daily lives, powering homes, businesses, and industries. Presently, electricity is generated largely by coal and other fossil fuels and nuclear power, with hydropower, and, to a lesser extent, renewable energy sources, such as wind. Because of electricity's importance to producers, consumers, and businesses, the federal government has undertaken a wide range of programs...
Nuclear Energy: NRC's Workforce and Processes for New Reactor Licensing Are Generally in Place, but Uncertainties Remain as Industry Begins to Submit Applications
GAO-07-1129: Published: Sep 21, 2007. Publicly Released: Sep 21, 2007.
Nearly three decades after the last order for a new nuclear power reactor in the United States, electric power companies plan to submit 20 applications in the next 18 months to the Nuclear Regulatory Commission (NRC) for licenses to build and operate new reactors. Since 1989, NRC has developed a new license review process that allows a power company to obtain a construction permit and an operating...
