This chart presents data on experts of U.S. highly-enriched uranium for civilian purposes. The data for 1957-2012 are taken from the "United States Nuclear Regulatory Commission Report to Congress on the Current Disposition of Highly Enriched Uranium Exports Used as Fuel or Targets in Nuclear Research or Test Reactors" (2014). The chart also presents data on export licenses granted by NRC after 2008. The actual amounts of material shipped abroad may not correspond to the amount in the license and the dates of shipments are normally not disclosed.
