DOE Project Management: NNSA Needs to Clarify Requirements for Its Plutonium Analysis Project at Los Alamos
GAO-16-585: Published: Aug 9, 2016. Publicly Released: Aug 9, 2016.
The Department of Energy's (DOE) National Nuclear Security Administration (NNSA) defined requirements for the revised Chemistry and Metallurgy Research Replacement (CMRR) project to provide plutonium analysis equipment at its Los Alamos site but did not specify the capacity for analyzing plutonium that the project should provide, making it possible that the project would not meet plutonium analysi...
Nuclear Waste: Waste Isolation Pilot Plant Recovery Demonstrates Cost and Schedule Requirements Needed for DOE Cleanup Operations
GAO-16-608: Published: Aug 4, 2016. Publicly Released: Aug 4, 2016.
The Department of Energy (DOE) did not meet its initial cost and schedule estimates for restarting nuclear waste disposal operations at the Waste Isolation Pilot Plant (WIPP), resulting in a cost increase of about $64 million and a delay of nearly 9 months. DOE incurred this cost increase and delay partly because it did not follow all best practices in developing the cost and schedule estimates. I...
Department of Energy: Observations on Efforts by NNSA and the Office of Environmental Management to Manage and Oversee the Nuclear Security Enterprise
GAO-16-422T: Published: Feb 23, 2016. Publicly Released: Feb 23, 2016.
The Department of Energy's (DOE) National Nuclear Security Administration (NNSA)—a separately organized agency within DOE—continues to face several ongoing challenges in modernizing the nuclear security enterprise, including challenges in managing life extension programs (LEP), contracts and major projects, and the alignment of plans with future budgets. As GAO reported in August 2015, NNSA es...
DOE Project Management: NNSA Should Ensure Equal Consideration of Alternatives for Lithium Production
GAO-15-525: Published: Jul 13, 2015. Publicly Released: Jul 13, 2015.
The National Nuclear Security Administration's (NNSA) has identified various challenges in its lithium production strategy that may impact its ability to meet demand for lithium in the future, as well as actions that may mitigate these challenges. These challenges pertain to three key areas. First, NNSA may not have a sufficient supply of lithium material for defense program requirements. NNSA off...
Hanford Waste Treatment: DOE Needs to Evaluate Alternatives to Recently Proposed Projects and Address Technical and Management Challenges
GAO-15-354: Published: May 7, 2015. Publicly Released: May 7, 2015.
The Department of Energy's (DOE) two proposed facilities may help achieve Hanford's waste treatment mission by expediting treatment of some waste and addressing some technical challenges within the Waste Treatment and Immobilization Plant's (WTP) Pretreatment facility. However, DOE selected the facilities based on past proposals and excluded other potential alternatives from consideration. One fac...
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...
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...
Nuclear Nonproliferation: Stronger Planning and Evaluation Needed for Radiological Security Zone Pilot Project
GAO-14-209: Published: Mar 6, 2014. Publicly Released: Mar 6, 2014.
Two U.S. agencies—the Nuclear Regulatory Commission (NRC) and the National Nuclear Security Administration (NNSA)—have several ongoing efforts, both in the United States and internationally, to secure radiological sources that could be used to make a terrorist weapon. These efforts include strengthening regulatory requirements, upgrading security, and recovering unwanted or abandoned radiologi...
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...
