Nuclear Weapons: Evaluation of Report on Feasibility of Increasing Air Transportation of Nuclear Weapons, Components, and Materials
GAO-12-577R: Published: May 4, 2012. Publicly Released: May 4, 2012.
In summary, we found the following:The ATS report was supported by generally acceptable methods for developing transportation options and evaluating safety, security, and operational requirements for these options. The assessment of safety risk from a possible airplane crash transporting nuclear weapons was the key factor supporting the reports conclusions to maintain the current balance of...
Department of Energy: Budget Trends and Oversight
GAO-12-659T: Published: Apr 18, 2012. Publicly Released: Apr 18, 2012.
Recent GAO work found that funding increases have expanded or created Department of Energy (DOE) programs with varying results. For example:Advanced Research Projects Agency-Energy (ARPA-E) awards grants to projects that help develop high-risk energy technologies. Since fiscal year 2009 the program has received $855 million to fund energy projects that industry by itself was not likely to undertak...
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...
National Nuclear Security Administration: Observations on NNSA's Management and Oversight of the Nuclear Security Enterprise
GAO-12-473T: Published: Feb 16, 2012. Publicly Released: Feb 16, 2012.
NNSA has successfully ensured that the nuclear weapons stockpile remains safe and reliable in the absence of underground nuclear testing, accomplishing this complicated task by using state-of-the-art facilities as well as the skills of top scientists. Nevertheless, NNSA does not have reliable enterprise-wide management information on program budgets and costs, which potentially increases risk to N...
Nuclear Weapons: NNSA Needs to Improve Guidance on Weapon Limitations and Planning for Its Stockpile Surveillance Program
GAO-12-188: Published: Feb 8, 2012. Publicly Released: Feb 8, 2012.
For the 52 NNSA identified limitations for all weapons in the U.S. nuclear stockpile, 86 percent fall into six types: detonation safety under abnormal conditions, weapon reliability, weapon delivery, more frequent replacement of limited life components, nuclear yield, and worker safety. Some DOD officials expressed concern over the impact that certain weapon limitations have on weapon operation, m...
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 Nonproliferation: Action Needed to Address NNSA's Program Management and Coordination Challenges
GAO-12-71: Published: Dec 14, 2011. Publicly Released: Dec 14, 2011.
:From fiscal years 2006 through 2010, only about half of the total annual funds available to the DNN programs were costed, or expended, each year. This resulted in uncosted carryover balances of more than $1.5 billion on average from one fiscal year to the next. During this time, the total uncosted DNN operating program balances exceeded thresholds established by the Department of Energy by hundre...
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...
Yucca Mountain: Information on Alternative Uses of the Site and Related Challenges
GAO-11-847: Published: Sep 16, 2011. Publicly Released: Oct 17, 2011.
The future of the Yucca Mountain project in Nevada--originally designated for permanent storage of nuclear waste--is uncertain. Since 1983, the Department of Energy (DOE) has spent billions of dollars to evaluate the Yucca Mountain site for potential use as a nuclear waste repository. In February 2010, the President proposed eliminating funding for the project, and in March 2010, DOE filed a motio...
