Bulk Fuel Pricing: DOD Needs to Reevaluate Its Approach to Better Manage the Effect of Market Fluctuations
GAO-14-595: Published: Jul 8, 2014. Publicly Released: Jul 8, 2014.
During fiscal years 2009 through 2013, the Department of Defense's (DOD) actual costs for bulk fuel differed considerably from its budget estimates, largely because of fluctuations in fuel price in the open market. During this period, DOD underestimated its costs for 3 years and overestimated them for 2 years as shown below. GAO identified two factors that contributed to the differences between es...
Fusion Energy: Actions Needed to Finalize Cost and Schedule Estimates for U.S. Contributions to an International Experimental Reactor
GAO-14-499: Published: Jun 5, 2014. Publicly Released: Jun 5, 2014.
Since the International Thermonuclear Experimental Reactor (ITER) Agreement was signed in 2006, the Department of Energy's (DOE) estimated cost for the U.S. portion of ITER has grown by almost $3 billion, and its estimated completion date has slipped by 20 years (see fig.). DOE has identified several reasons for the changes, such as increases in hardware cost estimates as designs and requirements...
Clear Air Force Station: Air Force Reviewed Costs and Benefits of Several Options before Deciding to Close the Power Plant
GAO-14-550: Published: May 12, 2014. Publicly Released: May 12, 2014.
The Air Force's decision to close the existing power plant at Clear Air Force Station is based, in part, on a 2010 study examining the feasibility of implementing alternative power sources at the installation in order to reduce operating costs while ensuring reliable power for the installation's mission. This study, along with other associated studies and analyses, initially led the Air Force to p...
Plutonium Disposition Program: DOE Needs to Analyze the Root Causes of Cost Increases and Develop Better Cost Estimates
GAO-14-231: Published: Feb 13, 2014. Publicly Released: Feb 13, 2014.
The Department of Energy's (DOE) National Nuclear Security Administration (NNSA) identified various drivers for the close to $3 billion increase in the estimated cost of the Plutonium Disposition program's two construction projects—the Mixed Oxide (MOX) Fuel Fabrication Facility and the Waste Solidification Building (WSB). These drivers included DOE's approval of the MOX facility's cost and sche...
Department of Energy: Observations on DOE's Management Challenges and Steps Taken to Address Them
GAO-13-767T: Published: Jul 24, 2013. Publicly Released: Jul 24, 2013.
As GAO has reported over the last decade, the Department of Energys (DOE) management of major projects and programs, security and safety at DOE sites, and reliable enterprise-wide management information, including budget and cost data, are among the most persistent management challenges the department faces. Challenges managing major projects and programs. The Office of Environmental M...
Department of Energy: Observations on Project and Program Cost Estimating in NNSA and the Office of Environmental Management
GAO-13-510T: Published: May 8, 2013. Publicly Released: May 8, 2013.
For more than a decade, GAO has reported on the challenges the Department of Energy's (DOE) National Nuclear Security Administration (NNSA) and the Office of Environmental Management (EM) have faced in meeting their projects' cost performance targets as developed in estimates and for ensuring that these cost estimates are based on sound assumptions. NNSA and EM are included on GAO's High-Risk List...
Department of Energy: Concerns with Major Construction Projects at the Office of Environmental Management and NNSA
GAO-13-484T: Published: Mar 20, 2013. Publicly Released: Mar 20, 2013.
In response to GAO reports over the past few years on management weaknesses in major projects (i.e., those costing $750 million or more), the Department of Energy (DOE) has undertaken a number of reforms since March 2009, including those overseen by the Office of Environmental Management (EM) and the National Nuclear Security Administration (NNSA). For example, DOE has updated program and project...
Nuclear Weapons: National Nuclear Security Administration's Plans for Its Uranium Processing Facility Should Better Reflect Funding Estimates and Technology Readiness
GAO-11-103: Published: Nov 19, 2010. Publicly Released: Nov 19, 2010.
Built in the 1940s and 1950s, the Y-12 National Security Complex, located in Oak Ridge, Tennessee, is the National Nuclear Security Administration's (NNSA) primary site for enriched uranium activities. Because Y-12 facilities are outdated and deteriorating, NNSA is building a more modern facility--known as the Uranium Processing Facility (UPF). NNSA estimates that the UPF will cost up to $3.5 bill...
Nuclear Waste: Actions Needed to Address Persistent Concerns with Efforts to Close Underground Radioactive Waste Tanks at DOE's Savannah River Site
GAO-10-816: Published: Sep 14, 2010. Publicly Released: Sep 14, 2010.
Decades of nuclear materials production at the Department of Energy's (DOE) Savannah River Site in South Carolina have left 37 million gallons of radioactive liquid waste in 49 underground storage tanks. In December 2008, DOE entered into a contract with Savannah River Remediation, LLC (SRR) to close, by 2017, 22 of the highest-risk tanks at a cost of $3.2 billion. GAO was asked to assess: (1) DOE...
Nuclear Nonproliferation: DOE Needs to Address Uncertainties with and Strengthen Independent Safety Oversight of Its Plutonium Disposition Program
GAO-10-378: Published: Mar 26, 2010. Publicly Released: Mar 26, 2010.
The end of the Cold War left the United States with a surplus of weapons-grade plutonium, which poses proliferation and safety risks. Much of this material is found in a key nuclear weapon component known as a pit. The Department of Energy (DOE) plans to dispose of at least 34 metric tons of plutonium by fabricating it into mixed oxide (MOX) fuel for domestic nuclear reactors. To do so, DOE's Nati...
