Modernizing the Nuclear Security Enterprise: Uranium Processing Facility is on Schedule and Budget, and NNSA Identified Additional Uranium Program Costs, Report to Congressional Committees [open pdf - 2MB]
From the GAO [Government Accountability Office] Highlights: "A supply of enriched uranium is crucial to support the nation's nuclear weapons stockpile and the U.S. Navy, but the infrastructure of several U.S. uranium-processing facilities is outdated. In 2014, NNSA [National Nuclear Security Administration] began plans to meet the nation's uranium needs by redirecting processing capabilities to the UPF and to other existing buildings NNSA plans to upgrade at Y-12 in Oak Ridge, Tennessee. The National Defense Authorization Act for Fiscal Year 2013, as amended, includes a provision for GAO to periodically review the UPF. Also, a Senate report accompanying the National Defense Authorization Act bill for fiscal year 2012 provides for GAO to review the independent cost estimates for the UPF. This report, which is GAO's sixth on the UPF, examines (1) the status of the UPF project and plans for starting UPF operations; (2) the extent to which NNSA has followed requirements to obtain independent cost estimates for the UPF, and how NNSA has used information from those estimates; and (3) the extent to which NNSA has made progress in developing uranium program management information since GAO's September 2017 report. GAO reviewed project and program documents on planning, schedule, cost, and implementation, and interviewed program officials."
