Karlsruhe Reprocessing Plant (WAK) Dismantling System. The Karlsruhe Reprocessing Plant (WAK) 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.
