Since the permanent shutdown of the Kori No. 1 reactor, research on nuclear power plant decommissioning has been actively conducted. The core facilities (reactor pressure vessel, steam generator, reactor coolant pump, and pressurizer) of a nuclear power plant have the highest radioactivity among the structures of a nuclear power plant, and the reactor pressure vessel (RPV) is the most radioactive object other than the nuclear fuel. In order to dismantle them, accurate preliminary information (2D, 3D models, etc.) and radiological characterization of the dismantling object are required, as well as feasibility studies of dismantling equipment and dismantling processes. However, it is impossible to review the dismantling process with only prior information and radiological characterization, and when using physical mock-ups, simulation and training in a virtual environment are necessary due to the difficulty of applying various dismantling equipment. In this paper, we developed a remote decommissioning training system that can improve the remote decommissioning technology of the nuclear power plant decommissioning process and the decommissioning skills of decommissioning workers by applying virtual reality and haptic technology.
