The Karlsruhe Reprocessing Plant (WAK), operated by the WAK–Betriebsgesellschaft (WAK-BG), was built between 1967 and 1971 by the former Nuclear Research Centre Karlsruhe. During its 20 years of hot operation, the WAK-plant processed 208 t of heavy metal, irradiated oxide fuel from research and power reactors. On June 30, 1991, the plant was finally closed down after a half-year nitric acid rinsing campaign. The dismantling of the plant started in 1994 with the decommissioning of obsolete systems and will be finished with a green field status. The dismantling activities were carried out by hands-on techniques, remote techniques, or a mixture of both, depending on radiological conditions. 5500 tons of contaminated solid waste, 3 200 m3 of liquid waste, 130 canisters of HLW glass, and 75 000 tons of rubble were created from dismantling the plant. The dismantling systems were: - Crane-like manipulator carrier system for two master slave manipulators. - Two electromechanical master slave manipulators with bilateral force feedback. - Manipulator-handled cutting tools and devices such as hydraulic shears, compass saw, disc grinder, etc. - Crane with contamination protection housing to transport material free of contamination into the WAK main cell hall. - Auxiliary crane and crane supported auxiliary manipulators for remote controlled recovery and repair work for the manipulator carrier system and master-slave-manipulators. - Passing and packaging systems - Control room for remote controlled operation.
