Management and Disposal of Graphite Waste

Radiological assessments were made of four generic options for disposal of packaged graphite: on the deep ocean bed, in deep geologic repositories at two different types of site, and by shallow land burial. Incineration of graphite was also considered, though this option presents logistical problems additional to those of direct disposal.

2005-1-16  to be taken into account during graphite waste processing and disposal. Different options have been studied for management of the radioactive graphite, but the final and generally accepted solution for its conditioning and/or disposal has not been decided yet. Disposal options proposed are near surface repositories and also deep geological formations.

Management of Radioactive Waste Containing

If reactor owners do not store the graphite components for a long time, one of the other two methods may be applied: decomposition of graphite elements or graphite recovery. For this purpose, several innovative techniques have been proposed, e.g., radionuclide transmutation, ultra- and nanofiltration of the liquid waste or the inclusion of solid waste into a matrix by the sol–gel method.
