The 3D Dynamic Simulation on the RSR and the Shielding Concrete Dismantling Process of the KRR-2

The 3D simulations of the shielding concrete and the Rotary Specimen Rack (RSR) in the Korea Research Reactor-1&2 (KRR-1&2) were carried out in present work. Four main dismantling processes, which are the removal of the RSR, reactor core region, beam tube, and thermal column and activated concrete, were selected for the graphic simulation by the consideration of the activation, worker training, work difficulty and so on. On the basis of those, we constructed their 3D CAD models, selected proper dismantling technologies, and reviewed their dismantling processes. In this study, the 3D simulation results of the shielding concrete and the RSR among main components are also presented and discussed.
