Nuclear Waste: Benefits and Costs Should Be Better Understood Before DOE Commits to a Separate Repository for Defense Waste
GAO-17-174: Published: Jan 31, 2017. Publicly Released: Jan 31, 2017.
The information that the Department of Energy (DOE) provided to the President about whether a separate defense waste repository was required did not quantify cited benefits, when possible, show how these benefits could be achieved, or show the risks if certain benefits could not be realized as planned. In the information provided to the President, DOE stated that separate repositories for defense...
National Nuclear Security Administration: A Plan Incorporating Leading Practices Is Needed to Guide Cost Reporting Improvement Effort
GAO-17-141: Published: Jan 19, 2017. Publicly Released: Jan 19, 2017.
On February 5, 2016, more than 13 months after the statutory reporting deadline, the National Nuclear Security Administration (NNSA) submitted to Congress a plan for improving and integrating its financial management. The plan includes the four elements required by the National Defense Authorization Act for Fiscal Year 2014—a feasibility assessment, estimated costs, expected results, and an impl...
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 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...
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...
DOE Loan Programs: Current Estimated Net Costs Include $2.2 Billion in Credit Subsidy, Plus Administrative Expenses
GAO-15-438: Published: Apr 27, 2015. Publicly Released: Apr 27, 2015.
The Department of Energy's (DOE) loan programs portfolio consists of 34 loans and loan guarantees totaling about $28 billion in support of 30 projects in a diverse array of technologies. DOE's Loan Guarantee Program (LGP) encourages certain types of energy projects by agreeing to reimburse lenders for the guaranteed amount of loans if the borrowers default. These guarantees have been for nuclear,...
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 Regulatory Commission: NRC Needs to Improve Its Cost Estimates by Incorporating More Best Practices
GAO-15-98: Published: Dec 12, 2014. Publicly Released: Dec 16, 2014.
The Nuclear Regulatory Commission's (NRC) overall cost estimating procedures incorporate some best practice characteristics identified in the GAO Cost Estimating and Assessment Guide (Cost Guide), but not others, and do not adequately support the creation of reliable cost estimates (see table). For example, while the procedures include the best practice of developing an estimating plan by outlinin...
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...
