Securing U.S. Nuclear Material: DOE Has Made Little Progress Consolidating and Disposing of Special Nuclear Material
GAO-08-72: Published: Oct 4, 2007. Publicly Released: Nov 5, 2007.
The Department of Energy (DOE) recognizes that a terrorist attack on a DOE site containing material that can be used in a nuclear weapon could have devastating consequences. DOE currently stores special nuclear material at 10 sites in 8 states. To reduce security costs, DOE plans to consolidate the material at fewer sites and dispose of material that it no longer needs. In 2005, DOE chartered the...
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 Security: DOE and NRC Have Different Security Requirements for Protecting Weapons-Grade Material from Terrorist Attacks
GAO-07-1197R: Published: Sep 11, 2007. Publicly Released: Sep 25, 2007.
In terrorists' hands, weapons-grade nuclear material--known as Category I special nuclear material when in specified forms and quantities--can be used to construct an improvised nuclear device capable of producing a nuclear explosion. Responsibility for the security of Category I special nuclear material is divided between the Department of Energy (DOE) and the Nuclear Regulatory Commission (NRC)...
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 Weapons: Annual Assessment of the Safety, Performance, and Reliability of the Nation's Stockpile
GAO-07-243R: Published: Feb 2, 2007. Publicly Released: Mar 5, 2007.
In 1992, the United States began a unilateral moratorium on the underground testing of nuclear weapons. Prior to the moratorium, underground nuclear testing was a critical component for evaluating and certifying nuclear warheads. In 1993, the Department of Energy (DOE), at the direction of the President and the Congress, established the Stockpile Stewardship Program to increase understanding of th...
Managing Sensitive Information: Actions Needed to Ensure Recent Changes in DOE Oversight Do Not Weaken an Effective Classification System
GAO-06-785: Published: Jun 30, 2006. Publicly Released: Jun 30, 2006.
In recent years, the Congress has become increasingly concerned that federal agencies are misclassifying information. Classified information is material containing national defense or foreign policy information determined by the U.S. government to require protection for reasons of national security. GAO was asked to assess the extent to which (1) DOE's training, guidance, and oversight ensure that...
Department of Energy: Additional Opportunities Exist for Reducing Laboratory Contractors' Support Costs
GAO-05-897: Published: Sep 9, 2005. Publicly Released: Oct 11, 2005.
In fiscal year 2004, about two-thirds of the Department of Energy's (DOE) $26.9 billion in spending went to 28 major facilities--laboratories, production and test facilities, and nuclear waste cleanup and storage facilities. DOE spent about $2.9 billion in fiscal year 2004 to support the mission of its five largest laboratories. GAO was asked to examine (1) recent trends in indirect and functional...
Nuclear Security: Actions Needed by DOE to Improve Security of Weapons-Grade Nuclear Material at Its Energy, Science and Environment Sites
GAO-05-934T: Published: Jul 26, 2005. Publicly Released: Jul 26, 2005.
A successful terrorist attack on a Department of Energy (DOE) site containing nuclear weapons material could have devastating effects for the site and nearby communities. DOE's Office of the Under Secretary for Energy, Science and Environment (ESE), which is responsible for DOE operations in areas such as energy research, manages five sites that contain weapons-grade nuclear material. A heavily ar...
