Decommissioning of Nuclear Power Plant Gundremmingen Unit A

Several nuclear power plants of the first generation have finished the nuclear life and retired in the status of decommissioning. In 1980 this significant milestone was settled for the nuclear power station KRB A. The reasons are quite similar for the international sister plants with the same status. The following phase of planning and evaluating a reasonable concept of decommissioning guided to the dismantling of unused systems in the turbine building. The experiences of dismantling, disassembling, decontamination and surveying measurement resulting from the treatment of 3000 tons materials released from the controlled area is described. The recycling of carbon steel for the production of waste containers made of cast iron is an important technique to reduce waste volume and has been performed with 1000 tons of steel scrap which is explained. Finally, an outlook towards the intended decommissioning steps in the reactor building is given
