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 Weapons: Technology Development Efforts for the Uranium Processing Facility
GAO-14-295: Published: Apr 18, 2014. Publicly Released: Apr 18, 2014.
GAO has identified five additional risks since its November 2010 report ( GAO-11-103 ) associated with using new technologies in the National Nuclear Security Administration's (NNSA) Uranium Processing Facility (UPF), which is to be built in three interrelated phases. These risks and the steps that NNSA is taking to address them include the following:Technology integration risks . An August 201...
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...
Hanford Waste Treatment Plant: DOE Needs to Take Action to Resolve Technical and Management Challenges
GAO-13-38: Published: Dec 19, 2012. Publicly Released: Jan 18, 2013.
The Department of Energy (DOE) faces significant technical challenges in successfully constructing and operating the Waste Treatment and Immobilization Plant (WTP) project that is to treat millions of gallons of highly radioactive liquid waste resulting from the production of nuclear weapons. DOE and Bechtel National, Inc. identified hundreds of technical challenges that vary in significance and p...
Nuclear Regulatory Commission: Oversight and Status of Implementing a Risk-Informed Approach to Fire Safety
GAO-13-8: Published: Oct 22, 2012. Publicly Released: Nov 26, 2012.
The Nuclear Regulatory Commission (NRC), together with plant operators, has made progress in resolving three fire safety issues raised in GAO's 2008 report by implementing GAO's recommendations or taking other actions. NRC implemented the recommendation on multiple spurious operations (malfunctions caused by fire that could cause safety-related equipment to malfunction) by issuing new guidance or...
Nuclear Nonproliferation: Additional Actions Needed to Improve Security of Radiological Sources at U.S. Medical Facilities
GAO-12-925: Published: Sep 10, 2012. Publicly Released: Sep 10, 2012.
The Nuclear Regulatory Commission's (NRC) requirements do not consistently ensure the security of high-risk radiological sources at the 26 selected hospitals and medical facilities GAO visited. One reason for this is that the requirements are broadly written and do not prescribe specific measures that hospitals and medical facilities must take to secure medical equipment containing sealed sources,...
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...
Nuclear Safety: Convention on Nuclear Safety Is Viewed by Most Member Countries as Strengthening Safety Worldwide
GAO-10-489: Published: Apr 29, 2010. Publicly Released: Jun 1, 2010.
Currently, 437 civilian nuclear power reactors are operating in 29 countries, and 56 more are under construction. After the Chernobyl accident, representatives of over 50 nations, including the United States, participated in the development of the Convention on Nuclear Safety, a treaty that seeks to promote the safety of civilian nuclear power reactors. The Convention has been in force since 1996...
