Nuclear Security: DOE Could Improve Aspects of Nuclear Security Reporting, Report to Congressional Committees [open pdf - 4MB]
"DOE [Department of Energy] and NNSA [National Nuclear Security Administration] operate sites with facilities holding special nuclear material that can be used to make nuclear weapons. The National Defense Authorization Act of 2014 requires the Secretary of Energy to submit to congressional committees a report detailing the status of security at sites holding key quantities of special nuclear material, along with a certification that the sites meet DOE's security standards and requirements by December 1 of each year. The law requires DOE's reports to include a similar report from NNSA. A report accompanying the legislation included a provision for GAO [Government Accountability Office] to evaluate these efforts. This report examines (1) the extent to which these DOE and NNSA reports meet the definition of quality information under federal internal control standards, and (2) any significant physical security challenges at sites that the reports or agency officials identified and the extent to which the agencies have addressed them. GAO reviewed the 2014 and 2015 reports and interviewed agency officials."
