  • Management of Radioactive Waste Containing Graphite

    It has been estimated that as a result of the decommissioning of one water-cooled graphite-moderated reactor about 1500–2000 tons of radioactive graphite waste is produced . According to data published in 2010 by the IAEA the world resources of i -graphite at that time were approximately 250 000 tons (160 000 cubic meters).
