On 12 October 2010, the U.S. National Nuclear Security Administration (NNSA) announced the removal of more than 450 kilograms (more than 1,000 pounds) of Russian-origin spent HEU fuel from Poland's Ewa and Maria research reactors located at the Nuclear Center in Swierk. The material was sent back to Russia in a series of five shipments over 12 months. With the removal of this material, the NNSA's Global Threat Reduction Initiative (GTRI) has completed the removal of all HEU from the Ewa reactor and the Spent Fuel Storage Building at the Institute of Atomic Energy. In August 2006 and August 2007, NNSA helped Poland return fresh HEU fuel to Russia. The United States has also provided Poland assistance in preparing for the conversion of the Maria research reactor from HEU to LEU fuel.
