Conference Article: Packaging requirements for graphite and carbon from the decommissioning of the AVR in consideration of the German final disposal regulations
Printz, R.J. (WTI GmbH, Juelich (Germany)); Quade, U. (SNU GmbH and Co., Krefeld (Germany)); Wahl, J. (AVR GmbH, Juelich (Germany))Abstract
Green field decommissioning of HTGR results in a large amount of activated graphite and carbon installations which have to be treated for final disposal in a safe and economic manner. In case of AVR decommissioning, 67 Mg of reflector graphite and 158 Mg of carbon isolation are highly contaminated and activated. A study for waste treatment recommended to package this graphite and carbon into cast iron moulded containers qualified for the planned German final depository KONRAD. The reference concept results in 364 cubic containers using up a final waste disposal volume of about 1.700 m3.
