Vitrification of the high-active liquid waste concentrates (HAWC) was a major milestone in the WAK decommissioning project (StiWAK). From September 2009 to June 2010, about 56 m{sup 3} of HAWC were vitrified at the Karlsruhe vitrification facility (VEK) and filled into 123 canisters. HAWC vitrification was followed by an extensive rinsing and shutdown program, in the course of which both the VEK process installations and the facilities for the storage and evaporation of high-active fission product solutions (LAVA) are prepared specifically for dismantling. Finally the rinsing programme leads to an overall reduction of the remaining contamination in the installations by a factor of approx. 5 - 10. The amount of liquids arisen from this program has been vitrified and another 17 canisters have been filled. In total, 140 canisters were packed into 5 CASTOR casks that were already transported to the Zwischenlager Nord (interim store North) of EWN GmbH (ZLN) in the mid of February 2011. The melter of the VEK was already shut down in the late November 2010. (authors)
