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...
Nuclear Weapons: Information on Safety Concerns with the Uranium Processing Facility
GAO-14-79R: Published: Oct 25, 2013. Publicly Released: Oct 25, 2013.
The Defense Nuclear Facilities Safety Board (Safety Board) has raised concerns with the National Nuclear Security Administration's (NNSA) plans to construct the Uranium Processing Facility (UPF), and NNSA has taken steps to address many of these concerns. Specifically:In 2009, NNSA--a separately organized agency within the Department of Energy (DOE)--decided to expedite the construction of the UPF...
Managing Critical Isotopes: Stewardship of Lithium-7 Is Needed to Ensure a Stable Supply
GAO-13-716: Published: Sep 19, 2013. Publicly Released: Oct 17, 2013.
Little is known about lithium-7 production in China and Russia and whether their supplies can meet future domestic demand. According to industry representatives, China and Russia produce enough lithium-7 to meet demand from U.S. pressurized water reactors, a type of commercial nuclear power reactor that requires lithium-7 for safe operation. However, China's continued supply may be reduced by its...
ICBM Modernization: Approaches to Basing Options and Interoperable Warhead Designs Need Better Planning and Synchronization
GAO-13-831: Published: Sep 20, 2013. Publicly Released: Sep 20, 2013.
The Department of Defense (DOD) has identified capability requirements and potential basing options for the Minuteman III follow-on intercontinental ballistic missile (ICBM), and the Department of Energy (DOE) has begun a parallel study of options to extend the life of its warhead, but neither department plans to estimate the total system costs for the new missile and its warhead. GAO's work on co...
Modernizing the Nuclear Security Enterprise: Observations on NNSA's Options for Meeting Its Plutonium Research Needs
GAO-13-533: Published: Sep 11, 2013. Publicly Released: Sep 11, 2013.
The National Nuclear Security Administration's (NNSA) Los Alamos National Laboratory's (LANL) April 2012 study (1) identified general options for meeting the plutonium research needs of NNSA--a separately organized agency within the Department of Energy (DOE)--during the several-year gap created by the deferral of the Chemistry and Metallurgy Research Replacement (CMRR) nuclear facility and (2) in...
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...
Nuclear Weapons: Factors Leading to Cost Increases with the Uranium Processing Facility
GAO-13-686R: Published: Jul 12, 2013. Publicly Released: Jul 12, 2013.
In summary, GAO found the following:Overly optimistic National Nuclear Security Administration (NNSA) assumptions about the Uranium Processing Facility (UPF) contained in multiple cost estimates prepared from 2004 to 2011 (upper bound of cost range was approximately $1.1 billion and $6.5 billion, respectively) are the primary factors that contributed to its cost increase. Initial NNSA UPF cost est...
National Nuclear Security Administration: Laboratories' Indirect Cost Management Has Improved, but Additional Opportunities Exist
GAO-13-534: Published: Jun 28, 2013. Publicly Released: Jun 28, 2013.
The National Nuclear Security Administrations (NNSA) management and operating (M&O) contractors differ in how they classify and allocate indirect costs at NNSA laboratories. Although different approaches are allowed by Cost Accounting Standards, these differences limit the ability to compare program costs across the laboratories. Recognizing the limitations of its current cost data, the Departme...
Worker Safety and Health at Department of Energy Sites
GAO-13-497R: Published: May 29, 2013. Publicly Released: May 29, 2013.
There are several key similarities and differences between Part 851, OSHA regulations, and the OSH Act. Several key similarities are that Part 851 incorporates by reference almost all OSHA standards and authorizes workers to file complaints about unsafe working conditions or hazards in the workplace. Several key differences are that Part 851 incorporates additional industry standards and authorize...
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...
