    For many years, Mitsubishi Heavy Industries, Ltd. (MHI) has been working on technological development related to the decommissioning of nuclear reactors, etc., centered on commercial nuclear power generation facilities. This effort has been based on the experience gained through the construction and maintenance of various nuclear facilities such as pressurized water nuclear power plants. The technologies required for decommissioning include the system engineering and residual radioactivity evaluation technology at the planning stage, the decontamination and dismantling technology at the full-blown work operation stage and the waste packaging, which is processing such as solidification to a container for buried processing of radioactive waste disposal and radioactivity measurement technology required for generated waste. This report introduces the latest state of the activities for each of these technologies.
