Department of Energy: Better Information Needed to Determine If Nonmajor Projects Meet Performance Targets
GAO-13-129: Published: Dec 19, 2012. Publicly Released: Jan 22, 2013.
Of the 71 nonmajor projects that the Department of Energy's (DOE) Office of Environmental Management (EM) and National Nuclear Security Administration (NNSA) completed or had under way from fiscal years 2008 to 2012, 21 met or are expected to meet their performance targets for scope, cost, and completion date. These projects included a $22 million EM project to expand an existing waste disposal fa...
Modernizing the Nuclear Security Enterprise: NNSA's Reviews of Budget Estimates and Decisions on Resource Trade-offs Need Strengthening
GAO-12-806: Published: Jul 31, 2012. Publicly Released: Jul 31, 2012.
The National Nuclear Security Administrations (NNSA) planning, programming, budgeting, and evaluation (PPBE) process provides a framework for the agency to plan, prioritize, fund, and evaluate its program activities. Formal policies guide NNSA and management and operating (M&O) contractors through each of four phases of the agencys PPBE cycleplanning, programming, budgeting, and...
Modernizing the Nuclear Security Enterprise: Observations on the Organization and Management of the National Nuclear Security Administration
GAO-12-867T: Published: Jun 27, 2012. Publicly Released: Jun 27, 2012.
After the enactment of Title 32 of the National Defense Authorization Act for Fiscal Year 2000 (NNSA Act), the Department of Energy (DOE) and the National Nuclear Security Administration (NNSA) struggled to determine how NNSA should operate as a separately organized agency within the department. A number of factors contributed to this. First, DOE and NNSA did not have a useful model to follow for...
Managing Critical Isotopes: DOE's Isotope Program Needs Better Planning for Setting Prices and Managing Production Risks
GAO-12-591: Published: May 23, 2012. Publicly Released: Jun 22, 2012.
The Department of Energys (DOE) Isotope Development and Production for Research and Applications program (Isotope Program) provides over 300 different isotopes for commercial and research applications. The Isotope Program is responsible for 243 stable isotopes that are no longer produced in the United States but are sold from the programs existing inventory and for 55 radioactive isoto...
Modernizing the Nuclear Security Enterprise: New Plutonium Research Facility at Los Alamos May Not Meet All Mission Needs
GAO-12-337: Published: Mar 26, 2012. Publicly Released: Mar 26, 2012.
The estimated cost to construct the CMRR has greatly increased since NNSAs initial plans, and the projects schedule has been significantly delayed. According to its most recent estimates prepared in April 2010, NNSA determined that the CMRR will cost between $3.7 billion and $5.8 billionnearly a six-fold increase from the initial estimate. Construction has also been repeatedly de...
Nuclear Nonproliferation: Further Actions Needed by U.S. Agencies to Secure Vulnerable Nuclear and Radiological Materials
GAO-12-512T: Published: Mar 14, 2012. Publicly Released: Mar 14, 2012.
The Presidents 4-year initiative is a worthwhile effort designed to accelerate U.S. and international efforts to secure nuclear material worldwide. However, as GAO reported in December 2010, the governmentwide strategy approved by the National Security Council (NSC) for the initiative lacked specific details regarding how the initiative will be implemented. As a result, key details associate...
DEPARTMENT OF ENERGY: Additional Opportunities Exist to Streamline Support Functions at NNSA and Office of Science Sites
GAO-12-255: Published: Jan 31, 2012. Publicly Released: Jan 31, 2012.
Support function costs at NNSA and Science sites for fiscal years 2007 through 2011 are not fully known because DOE changed its data collection approach beginning in 2010 to improve its data and, as a result, does not have complete and comparable cost data for all years. In fiscal years 2007 through 2009, total support costs for NNSA and Science sites grew from $5 billion to about $5.5 billion (no...
Nuclear Fuel Cycle Options: DOE Needs to Enhance Planning for Technology Assessment and Collaboration with Industry and Other Countries
GAO-12-70: Published: Oct 17, 2011. Publicly Released: Nov 17, 2011.
More demand for electricity and concerns about greenhouse gas emissions have increased interest in nuclear power, which does not rely on fossil fuels. However, concerns remain about the radioactive spent fuel that nuclear reactors generate. The Department of Energy (DOE) issued a research and development (R&D) plan to select nuclear fuel cycles and technologies, some of which reprocess spent fuel...
Managing Critical Isotopes: Weaknesses in DOE's Management of Helium-3 Delayed the Federal Response to a Critical Supply Shortage
GAO-11-472: Published: May 12, 2011. Publicly Released: May 31, 2011.
Helium-3 gas is a key component of equipment used at ports and border crossings to detect radiation and prevent the smuggling of nuclear material into the United States, among other uses. The National Nuclear Security Administration (NNSA), a separate agency within the Department of Energy (DOE), extracts helium-3 and controls the inventory. Since 2003, NNSA has made helium-3 available for sale to...
Nuclear Nonproliferation: DOE Needs to Address Uncertainties with and Strengthen Independent Safety Oversight of Its Plutonium Disposition Program
GAO-10-378: Published: Mar 26, 2010. Publicly Released: Mar 26, 2010.
The end of the Cold War left the United States with a surplus of weapons-grade plutonium, which poses proliferation and safety risks. Much of this material is found in a key nuclear weapon component known as a pit. The Department of Energy (DOE) plans to dispose of at least 34 metric tons of plutonium by fabricating it into mixed oxide (MOX) fuel for domestic nuclear reactors. To do so, DOE's Nati...
