Diamond chips could be key to decommissioning of Fukushima nuclear plant
As decommissioning of the Fukushima No. 1 nuclear powerplant progresses, diamond semiconductors from Sapporo-based Ookuma Diamond Device may enhance the removal of melted debris. The startup aims for practical use by fiscal 2026, following the construction of a facility in Okuma, Fukushima Prefecture.
Key points
- Fukushima No. 1 nuclear powerplant is undergoing decommissioning after a meltdown.
- Diamond semiconductors can withstand intense nuclear radiation, making them suitable for the decommissioning process.
- Ookuma Diamond Device plans to produce these diamond chips, leveraging this unique application.
- Construction of a production facility in Okuma, Fukushima, starts this month.
- The target for practical application is set for fiscal 2026.
Why it matters
- This development ties into a growing trend in IT of utilizing advanced materials such as diamond semiconductors for high-radiation environments.
- As of 2023, there is increased global focus on safe nuclear decommissioning technologies, part of the broader sustainability movement.
The use of diamond chips in Fukushima's decommissioning signifies a potential breakthrough in nuclear safety technology, aligning with the global push for innovation in handling hazardous environments.
