Nuclear Material: Agencies Have Sound Procedures for Managing Exchanges but Could Improve Inventory Monitoring
GAO-16-713: Published: Sep 23, 2016. Publicly Released: Oct 24, 2016.
In the United States, from October 1, 2003, through November 30, 2015, there were 817 exchanges of nuclear material that carried obligations to foreign partners under nuclear cooperation agreements. These exchanges allowed the obligated nuclear material to be transferred between U.S. facilities without physically moving it. For example, if a facility had a certain amount of obligated nuclear mater...
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...
Federal Research: Information on DOE's Laboratory-Directed Research and Development Program
GAO-16-486R: Published: Apr 8, 2016. Publicly Released: Apr 8, 2016.
For fiscal year 2015, the National Nuclear Security Administration’s (NNSA) authorized Laboratory-Directed Research and Development (LDRD) funding limit, expressed as a percentage, was the same as the LDRD funding limit for other Department of Energy (DOE) laboratories. Specifically, DOE’s LDRD policy directs NNSA and other DOE laboratories to comply with statutory limits—for fiscal year 201...
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...
Department of Energy: Actions Needed to Improve DOE and NNSA Oversight of Management and Operating Contractors
GAO-15-662T: Published: Jun 12, 2015. Publicly Released: Jun 12, 2015.
In May 2015, GAO found that the Department of Energy's (DOE) National Nuclear Security Administration (NNSA) had not fully established policy or guidance for using information from contractor assurance systems (CAS) to conduct oversight of management and operating (M&O) contractors. NNSA did not provide comprehensive guidance to agency officials on how to conduct assessments required by its oversi...
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...
DOE and NNSA Project Management: Analysis of Alternatives Could Be Improved by Incorporating Best Practices
GAO-15-37: Published: Dec 11, 2014. Publicly Released: Dec 11, 2014.
GAO identified 24 best practices for analysis of alternatives (AOA)—a process that is a key first step in capital asset acquisition. The process entails identifying, analyzing, and selecting a preferred alternative to best meet the mission need by comparing the operational effectiveness, costs, and risks of potential alternatives. Because no single set of best practices for AOAs was broadly reco...
Project and Program Management: DOE Needs to Revise Requirements and Guidance for Cost Estimating and Related Reviews
GAO-15-29: Published: Nov 25, 2014. Publicly Released: Nov 25, 2014.
The Department of Energy's (DOE) and its National Nuclear Security Administration's (NNSA) cost estimating requirements and guidance for projects and programs do not fully reflect best practices for developing cost estimates. In regard to cost estimating requirements for projects, DOE's 2010 project management order requires 1 of the 12 cost estimating best practices—conducting an independent co...
Nuclear Security: NNSA Should Establish a Clear Vision and Path Forward for Its Security Program
GAO-14-208: Published: May 30, 2014. Publicly Released: Jun 30, 2014.
Implementation of security reforms from 2009 to 2012 generally varied among National Nuclear Security Administration (NNSA) sites. According to Department of Energy (DOE) and NNSA officials and contractors, some of these efforts helped manage security costs and enhance productivity, among other benefits, but may also have increased security risks and reduced security performance at the Y-12 Nation...
