The Y-12 National Security Complex of the U.S. National Nuclear Security Administration (NNSA) filed a request with NRC for an amendment of a license XSNM3622, issued in 2010, to export HEU to Europe. The new request, XSNM3622/01, was submitted on May 30, 2012.

The new request covers two separate amounts of U-235. The first was covered by the original 2010 license - "87.3 kg of U-235 contained in maximum of 93.5 kg of uranium enriched to maximum of 93.35% in the form of broken metal." It is listed as "previously shipped in 10/2010." It was used as driver fuel in the BR2 reactor in Belgium.

The additional amount of HEU - "5.8 kg of U-235 contained in maximum of 6.2 kg of uranium enriched to maximum of 93.35% [the maximum enrichment is also listed as 93.2%] in the form of broken metal" - will be supplied to produce medical isotopes in the Institute for Radioelements (IRE) in Belgium. The material will be used to produce targets for irradiation in the following reactors: BR2 in Belgium, HFR Petten in the Netherlands, OSIRIS in France, and LVR-15 reactor in Czech Republic. Fuel and target fabrication is expected to be done at CERCA Areva facility in France.

UPDATE: The license XSNM3622/01 was issued on 6 September 2012. The LVR-15 reactor was not included in the license.
