Chubu Electric Power Group Report 2021(Integrated Report)

In the reprocessing of spent nuclear fuels from nuclear power generation, 5% that remains after recovering reusable materials becomes liquid high-level waste. It then undergoes the vitrication process and becomes high-level radioactive waste that requires geological disposal. The Nuclear Waste Management Organization of Japan (NUMO), leading the effort of geological disposal of radioactive waste, initiated a literature survey in November 2020 in Suttsu-cho and Kamoenai-mura, both in Hokkaido. As we have a basic responsibility regarding this matter as a generator of high-level radioactive waste, Chubu Electric Power has been working with the national government and NUMO and accordingly undertaking activities, such as proactively disseminating relevant information.We had conducted an activity to visit and hold dialogues with each of the local residents living in the areas around the power station since 2014. This activity is temporarily suspended from the viewpoint of preventing the spread of COVID-19. Under the pandemic, we are strengthening our ability to disseminate information via leaets distributed by direct mail and with newspaper, and at the same time, increasing two-way communication using certain media, for example by soliciting customers’ opinions through questionnaire surveys.Progress status of the decommissioning of Hamaoka Nuclear Power Station Units 1 and 2Leaet distributed via direct mail* Task of removing radioactive substances from within the reactor using chemicalsPower station toursWe host tours of the Hamaoka Nuclear Power Station for local residents and companies in the areas around the power station to explain a mechanism of nuclear power generation and other related topics and provide an opportunity for them to actually see the station’s safety improvement measures on-site.Opinion-exchange meetings and briengsWe hold opinion-exchange meetings with local residents in the areas around the power station to talk about questions and concerns about nuclear power generation and other matters of interest in a group work format to deepen mutual understanding. We also provide briengs on the latest status of the power station at meetings of local residents’ associations and other occasions.Power plant “caravans”We hold briefing sessions in shopping centers and at local events held in the areas around the power station for the purpose of providing explanations to local residents about the need for nuclear power generation and the measures of safety improvement at the power station and hearing opinions of them.TOPICSProject for geological disposal of high-level radioactive waste* For details, please visit NUMO’s website.Initiatives toward Utilization of the Hamaoka Nuclear Power StationBy utilizing various opportunities, we explain our efforts made at the Hamaoka Nuclear Power Station. At the same time, we conduct ongoing activities to listen to the voice of local residents and respond earnestly to their concerns, questions, and opinions.Strengthening risk communicationAs the second stage of decommissioning of Units 1 and 2 of the Hamaoka Nuclear Power Station, we have been conducting the dismantling of surrounding equipment, in particular, the dismantling of the equipment in the turbine building. In the third stage, decontamination of the reactor* will be conducted as preparation to dismantle the reactor area. We will continue to treat safety as our highest priority and steadily proceed with the decommissioning process as the leader in Japan’s rst decommissioning of a commercial light-water reactor.
