GAO-15-331: Published: Mar 23, 2015. Publicly Released: Mar 23, 2015.
The National Nuclear Security Administration's (NNSA) report to Congress on the competition of the consolidated management and operating (M&O) contract for its Pantex Plant in Texas and Y-12 National Security Complex (Y-12) in Tennessee includes information on all the statutorily required topics but does not clearly or completely describe expected benefits and costs. Specifically:• Key analyses...
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 Facilities: Better Prioritization and Life Cycle Cost Analysis Would Improve Disposition Planning
GAO-15-272: Published: Mar 19, 2015. Publicly Released: Mar 19, 2015.
The National Nuclear Security Administration (NNSA) has identified 83 facilities at six of its eight sites for transfer to the Department of Energy's (DOE) Office of Environmental Management (EM) for disposition, and the condition of NNSA's facilities awaiting transfer continues to degrade. NNSA plans to transfer all 83 facilities to EM over the next 25 years. Twenty-seven of them are still operat...
Defense Science and Technology: Further DOD and DOE Actions Needed to Provide Timely Conference Decisions and Analyze Risks from Changes in Participation [Reissued on March 13, 2015]
GAO-15-278: Published: Mar 4, 2015. Publicly Released: Mar 4, 2015.
Department of Defense (DOD) and Department of Energy (DOE) officials cited reduced attendance at science and technology (S&T) conferences by scientists and engineers since DOD and DOE implemented their conference policies. These policies, responding to Office of Management and Budget (OMB) requirements, established processes for senior-level review and approval of conference requests based on depa...
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 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...
National Nuclear Security Administration: Agency Expanded Use of Some Federal Oversight Reforms, but Is Still Determining Future Plans
GAO-14-588: Published: Jul 17, 2014. Publicly Released: Jul 17, 2014.
Key reforms at the National Nuclear Security Administration's (NNSA) Kansas City Plant (KCP)—a site in Missouri that manufactures electronic and other nonnuclear components of nuclear weapons—included (1) streamlining operating requirements by replacing Department of Energy (DOE) requirements with industry standards, where appropriate; (2) refocusing federal oversight to rely on contractor per...
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...
Nuclear Nonproliferation: Additional Actions Needed to Increase the Security of U.S. Industrial Radiological Sources
GAO-14-293: Published: Jun 6, 2014. Publicly Released: Jun 12, 2014.
GAO found that challenges exist in reducing the security risks faced by licensees using high-risk industrial radiological sources. Specifically, licensees face challenges in (1) securing mobile and stationary sources and (2) protecting against an insider threat. Regarding mobile sources, their portability makes them susceptible to theft or loss, as the size of some of these sources is small enough...
