The decontamination and crushing of reinforced concrete is a key aspect of the dismantling of nuclear facilities. The main aim is to selectively remove the contaminated material in order to be able to feed the remaining material, which represents the majority of the total plant or total mass, into the normal recycling cycle. Several methods are already available for surface decontamination. One problem currently exists in the demolition and selective deep removal of reinforced concrete, e.g. in the case of cracks or break-outs, so that the surfaces are subsequently suitable for measuring. A promising approach to solving this problem was presented as part of the previous "INAS" research project. Building on this positive experience, the joint project "Defined removal of highly reinforced concrete structures" (DefAhS) aims to investigate the problems and issues that have arisen in detail in order to lay the foundations for the subsequent development of a practical removal device. To this end, the individual removal methods are to be optimized accordingly. To ensure that the individual methods are not unnecessarily overloaded beyond their operational limits, the resulting demonstrator is also to be given the option of detecting reinforcement layers. This will enable a high degree of operational reliability and tool service life to be achieved. The Chair of Mobile Machinery at the Institute of Automotive Engineering at KIT is in charge of the possibilities and implementation of the detection. Through a constant exchange of new findings and results with the other project partners, the overall system is advantageously supplemented and makes it possible to present a functional demonstrator and test it in situ.
