Nuclear Regulatory Commission: Changes Planned to Budget Structure and Justification
GAO-17-294: Published: Mar 8, 2017. Publicly Released: Mar 8, 2017.
The Nuclear Regulatory Commission's budget increased 59 percent from fiscal year 2005 through 2010 in anticipation of growth in the commercial nuclear industry. When this growth did not occur, NRC began to reduce its budget, with a decrease of 6 percent since 2010. We found that some changes in NRC’s budget, such as how it budgeted for overhead, had the unintended consequence of appearing to in...
Iran Nuclear Agreement: The International Atomic Energy Agency's Authorities, Resources, and Challenges
GAO-16-565: Published: Jun 9, 2016. Publicly Released: Jul 14, 2016.
As outlined in the Joint Comprehensive Plan of Action (JCPOA), the International Atomic Energy Agency (IAEA) was asked to verify and monitor Iran's implementation of a range of nuclear-related commitments. IAEA is using its safeguards authorities and conducting additional activities agreed to by Iran under the JCPOA to do so. Iran's commitments include limits on uranium enrichment levels and on en...
Department of Energy: Management of Excess Uranium
GAO-15-475T: Published: Apr 22, 2015. Publicly Released: Apr 22, 2015.
GAO has identified four key issues related to the Department of Energy's (DOE) management of excess uranium and uranium transfers in reports, testimonies, and a legal opinion issued since 2006 as follows:Elimination of a guideline to limit DOE's annual uranium sales and transfers. In May 2014, GAO found DOE's decision to discontinue its 10 percent guideline for limiting uranium sales and transfers...
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...
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...
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 Safety: Convention on Nuclear Safety Survey (GAO-10-550SP, April 2010), an E-supplement to GAO-10-489
GAO-10-550SP: Published: Apr 29, 2010. Publicly Released: Jun 1, 2010.
This document is an E-supplement to GAO-10-489. It presents the results of GAOs survey of the contracting parties to the Convention on Nuclear Safety. This survey was a key component of GAO's effort to gather information about the perceived effectiveness of the Convention in improving nuclear safety worldwide. The objectives of this survey were to determine which aspects of the Convention are work...
Fusion Energy: Definitive Cost Estimates for U.S. Contributions to an International Experimental Reactor and Better Coordinated DOE Research Are Needed
GAO-08-30: Published: Oct 26, 2007. Publicly Released: Oct 26, 2007.
The United States is pursuing two paths to fusion energy--magnetic and inertial. On November 21, 2006, the United States signed an agreement with five countries and the European Union to build and operate the International Thermonuclear Experimental Reactor (ITER) in Cadarache, France, to demonstrate the feasibility of magnetic fusion energy. The United States also built and operates facilities to...
Nuclear Energy: NRC's Workforce and Processes for New Reactor Licensing Are Generally in Place, but Uncertainties Remain as Industry Begins to Submit Applications
GAO-07-1129: Published: Sep 21, 2007. Publicly Released: Sep 21, 2007.
Nearly three decades after the last order for a new nuclear power reactor in the United States, electric power companies plan to submit 20 applications in the next 18 months to the Nuclear Regulatory Commission (NRC) for licenses to build and operate new reactors. Since 1989, NRC has developed a new license review process that allows a power company to obtain a construction permit and an operating...
Nuclear Regulation: NRC Needs to More Aggressively and Comprehensively Resolve Issues Related to the Davis-Besse Nuclear Power Plant's Shutdown
GAO-04-415: Published: May 17, 2004. Publicly Released: May 18, 2004.
In March 2002, the most serious safety issue confronting the nation's commercial nuclear power industry since Three Mile Island in 1979 was identified at the Davis- Besse plant in Ohio. After the Nuclear Regulatory Commission (NRC) allowed Davis-Besse to delay shutting down to inspect its reactor vessel for cracked tubing, the plant found that leakage from these tubes had caused extensive corrosio...
