Compact Sodium-cooled Nuclear Reactor Facility (KNK2) Remote Dismantling System. The KNK (Kompakte Natrium Kernreaktoranlage) plant was to be decommissioned completely in ten steps, i.e. under the corresponding ten decommissioning permits, to reach green field condition at the end of 2018. To date, nine decommissioning permits have been issued. The decommissioning and demolition activities of steps 1 to 8 have been completed. Under the 9th decommissioning permit removal of the reactor vessel with its internals was completed in April 2008. The following steps of the 9th permission include the dismantling of the heat insulation, the primary shield and the activated part of the biological shield.
