Modernizing the Nuclear Security Enterprise: Observations on the National Nuclear Security Administration's Oversight of Safety, Security, and Project Management
GAO-12-912T: Published: Sep 12, 2012. Publicly Released: Sep 12, 2012.
The National Nuclear Security Administration (NNSA), a separately organized agency within the Department of Energy (DOE), has successfully ensured that the nuclear weapons stockpile remains safe and reliable by using state-of-the-art facilities as well as the skills of top scientists. Nevertheless, DOEs and NNSAs ineffective oversight of its contractors has contributed to many safety a...
Nuclear Safety: Construction of the Protective Shelter for the Chernobyl Nuclear Reactor Faces Schedule Delays, Potential Cost Increases, and Technical Uncertainties
GAO-07-923: Published: Jul 19, 2007. Publicly Released: Jul 26, 2007.
In 1986, an explosion at the Chernobyl nuclear power plant in Ukraine destroyed the reactor building and released massive amounts of radioactive contamination. A temporary shelter was built over the damaged reactor to prevent further contamination. The United States is a major donor to an international project to build a new shelter to replace the existing one, which is badly deteriorating. GAO wa...
Nuclear Waste: Better Performance Reporting Needed to Assess DOE's Ability to Achieve the Goals of the Accelerated Cleanup Program
GAO-05-764: Published: Jul 29, 2005. Publicly Released: Jul 29, 2005.
In February 2002, following years of rising costs to its nuclear waste cleanup program, the Department of Energy (DOE) announced a new initiative--the accelerated cleanup plan--and committed to reduce costs of cleanup by $50 billion, shorten the cleanup schedule by 35 years, and reduce risks to human health and the environment. GAO reviewed (1) the progress DOE has made under its accelerated clean...
Nuclear Nonproliferation: Limited Progress in Improving Nuclear Material Security in Russia and the Newly Independent States
RCED/NSIAD-00-82: Published: Mar 6, 2000. Publicly Released: Mar 6, 2000.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) Material Protection, Control, and Accounting program, which is designed to improve nuclear material security in Russian facilities, focusing on the: (1) number of buildings that have received nuclear material security systems and the amount of nuclear material that is protected under the systems; and (2) program's c...
