Remote dismantling and packaging of reactor pressure vessel internals and core scrap at Brunsbüttel nuclear power plant

As part of the dismantling of the Brunsbüttel nuclear power plant (KKB), the dismantling and packaging of the internals of the reactor pressure vessel represents an important step in order to further reduce the radiological inventory still contained after the fuel has been transported away. The reactor pressure vessel (RPV) internals of this boiling water reactor (BWR) consist primarily of the major components steam dryer, steam-water separator, upper and lower core grid, control rod guide tubes and core shroud. All of these components with a total mass of approx. 180 t have to be dismantled and packed for disposal. Due to their radiological properties, this is done remotely or remotely under water, using safe, reliable and flexible technical solutions.
