Energy Policy: Information on Federal and Other Factors Influencing U.S. Energy Production and Consumption from 2000 through 2013
GAO-14-836: Published: Sep 30, 2014. Publicly Released: Oct 30, 2014.
According to the studies and reports GAO reviewed, several major factors, including federal activities, influenced U.S. production and consumption of fossil, nuclear, and renewable energy from 2000 through 2013. Examples of these factors include the following:Fossil energy. Advances in drilling technologies enabled economic production of natural gas and crude oil from shale and similar geological...
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...
Advanced Reactor Research: DOE Supports Multiple Technologies, but Actions Needed to Ensure a Prototype Is Built
GAO-14-545: Published: Jun 23, 2014. Publicly Released: Jun 23, 2014.
The Department of Energy's (DOE) Office of Nuclear Energy's (NE) approach to advanced reactor research and development (R&D) focuses on three reactor technologies—high-temperature gas-cooled reactors, sodium-cooled fast reactors, and fluoride-salt-cooled high-temperature reactors—but NE is also funding research into other advanced reactor technologies. NE's approach is to conduct research in s...
Department of Energy: Enhanced Transparency Could Clarify Costs, Market Impact, Risk, and Legal Authority to Conduct Future Uranium Transactions
GAO-14-291: Published: May 9, 2014. Publicly Released: Jun 9, 2014.
The Department of Energy (DOE) undertook four uranium transactions involving USEC Inc. (USEC) in 2012 and 2013. These transactions served to provide the company with operating cash. According to DOE, the department benefited from these transactions in two ways: (1) by ensuring availability of domestic low-enriched uranium (LEU) for the production of tritium, a key radioactive isotope used to enhan...
Nuclear Safety: Countries' Regulatory Bodies Have Made Changes in Response to the Fukushima Daiichi Accident
GAO-14-109: Published: Mar 6, 2014. Publicly Released: Mar 11, 2014.
All the nuclear regulatory bodies in the 16 selected countries in GAO's review—13 of which currently operate nuclear power reactors and 3 of which are developing or considering developing civilian nuclear power programs—have taken steps to strengthen nuclear safety in response to the Fukushima Daiichi accident in Japan. Japan in particular has fundamentally restructured its nuclear regulatory...
Nuclear Nonproliferation: Stronger Planning and Evaluation Needed for Radiological Security Zone Pilot Project
GAO-14-209: Published: Mar 6, 2014. Publicly Released: Mar 6, 2014.
Two U.S. agencies—the Nuclear Regulatory Commission (NRC) and the National Nuclear Security Administration (NNSA)—have several ongoing efforts, both in the United States and internationally, to secure radiological sources that could be used to make a terrorist weapon. These efforts include strengthening regulatory requirements, upgrading security, and recovering unwanted or abandoned radiologi...
Nuclear Weapons: Factors Leading to Cost Increases with the Uranium Processing Facility
GAO-13-686R: Published: Jul 12, 2013. Publicly Released: Jul 12, 2013.
In summary, GAO found the following:Overly optimistic National Nuclear Security Administration (NNSA) assumptions about the Uranium Processing Facility (UPF) contained in multiple cost estimates prepared from 2004 to 2011 (upper bound of cost range was approximately $1.1 billion and $6.5 billion, respectively) are the primary factors that contributed to its cost increase. Initial NNSA UPF cost est...
Wind Energy: Additional Actions Could Help Ensure Effective Use of Federal Financial Support
GAO-13-136: Published: Mar 11, 2013. Publicly Released: Mar 28, 2013.
GAO identified 82 federal wind-related initiatives, with a variety of key characteristics, implemented by nine agencies in fiscal year 2011. Five agencies--the Departments of Energy (DOE), the Interior, Agriculture (USDA), Commerce, and the Treasury--collectively implemented 73 of the initiatives. The 82 initiatives incurred about $2.9 billion in wind-related obligations and provided estimated win...
Department of Energy: Concerns with Major Construction Projects at the Office of Environmental Management and NNSA
GAO-13-484T: Published: Mar 20, 2013. Publicly Released: Mar 20, 2013.
In response to GAO reports over the past few years on management weaknesses in major projects (i.e., those costing $750 million or more), the Department of Energy (DOE) has undertaken a number of reforms since March 2009, including those overseen by the Office of Environmental Management (EM) and the National Nuclear Security Administration (NNSA). For example, DOE has updated program and project...
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...
