Diamond chips may aid Fukushima nuclear plant decommissioning

Diamond chips are being considered for use in the decommissioning of the Fukushima No. 1 nuclear power plant. These chips can endure high radiation, voltages, and temperatures, making them suitable for the challenging environment. Ookuma Diamond Device, a startup from Sapporo, plans to use these diamond semiconductors in the decommissioning process. The company aims to have them ready for practical use by fiscal 2026. Construction of a production facility in Okuma, Fukushima Prefecture, has begun this month. This facility will support the development of the diamond chips for the nuclear plant's decommissioning efforts.
