Spent fuel of Rossendorf research reactor to be shipped to Russia
Germany's nuclear regulator, Federal Office for Radiation Protection (BfS), gave its approval to a shipment of spent fuel of the research reactor in Rossendorf, East Germany, to Russia. The shipment will include 951 irradiated fuel assemblies that contain 349 kg of uranium and plutonium (according to one report, the spent fuel contains 54.6 kg of U-235 and 2 kg of plutonium).
