Nuclear Weapons: NNSA Has a New Approach to Managing the B61-12 Life Extension, but a Constrained Schedule and Other Risks Remain
GAO-16-218: Published: Feb 4, 2016. Publicly Released: Feb 4, 2016.
The B61-12 life extension program's (LEP) managers have developed a management approach that officials from the Department of Energy's (DOE) National Nuclear Security Administration (NNSA) and the Department of Defense (DOD) regard as improved over the management approach used for past LEPs, which experienced schedule delays and cost overruns. Among other things, the B61-12 LEP is the first LEP to...
Defense Infrastructure: Energy Conservation Investment Program Needs Improved Reporting, Measurement, and Guidance
GAO-16-162: Published: Jan 29, 2016. Publicly Released: Jan 29, 2016.
The Department of Defense (DOD) collects information on how Energy Conservation Investment Program (ECIP) projects are expected to perform when operational, including anticipated returns on investment and energy or water savings. While DOD annually notifies congressional committees of proposed ECIP projects and includes some of this performance information with the notification, it does not do so...
National Nuclear Security Administration: Observations on Management Challenges and Steps Taken to Address Them
GAO-15-532T: Published: Apr 15, 2015. Publicly Released: Apr 15, 2015.
The National Nuclear Security Administration (NNSA) faces challenges implementing its plans to modernize the nuclear security enterprise. In its November 2014 report, the Augustine-Mies Panel observed that NNSA's Stockpile Stewardship Management Plan, which is intended to communicate long-range plans and cost estimates, has varied from year to year in the costs and schedules for the delivery of se...
Nuclear Waste: DOE Needs to Improve Cost Estimates for Transuranic Waste Projects at Los Alamos
GAO-15-182: Published: Feb 18, 2015. Publicly Released: Mar 23, 2015.
The National Nuclear Security Administration's (NNSA) project to remove transuranic (TRU) waste—primarily discarded equipment and soils contaminated with certain radioactive material—at Los Alamos National Laboratory (LANL) did not meet its cost estimates. At the end of fiscal year 2014, NNSA had spent about $931 million on the project, exceeding its 2006 estimate of $729 million by $202 milli...
Nuclear Weapons: Some Actions Have Been Taken to Address Challenges with the Uranium Processing Facility Design
GAO-15-126: Published: Oct 10, 2014. Publicly Released: Oct 10, 2014.
In January 2013, the National Nuclear Security Administration (NNSA) completed a review to identify the factors that contributed to the space/fit issue with the Uranium Processing Facility (UPF), and identified a number of factors within both NNSA and the contractor managing the UPF design at that time. NNSA's review identified shortcomings in 1) federal oversight of the project, 2) design integra...
Fusion Energy: Observations on DOE's Cost and Schedule Estimates for U.S. Contributions to an International Experimental Reactor
GAO-14-750T: Published: Jul 11, 2014. Publicly Released: Jul 11, 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. DOE has identified several reasons for the changes, such as increases in hardware cost estimates as designs and requirements have been m...
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...
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...
Modernizing the Nuclear Security Enterprise: NNSA's Budget Estimates Do Not Fully Align with Plans
GAO-14-45: Published: Dec 11, 2013. Publicly Released: Dec 11, 2013.
The National Nuclear Security Administration's (NNSA) total budget estimates for modernizing the nuclear security enterprise for fiscal years 2014 through 2031 have increased by about $19 billion overall when compared with the estimates in the agency's fiscal year 2012 budget materials, with most of the increase occurring in fiscal year 2019 and beyond. Factors such as sequestration, the achievabi...
National Laboratories: DOE Needs to Improve Oversight of Work Performed for Non-DOE Entities
GAO-14-78: Published: Oct 25, 2013. Publicly Released: Nov 25, 2013.
In fiscal years 2008 through 2012, the Department of Energy (DOE) performed about $2 billion annually of Work for Others (WFO) projects, as measured by the costs incurred. Although the amount of WFO performed has remained relatively constant over the last 5 years overall, WFO as a percentage of the total work performed at the laboratories--measured in total laboratory costs incurred--has declined...
