US EditionTepco Unveils New Robot Arm for Nuclear Debris Removal
The 22-meter robot arm can retrieve debris from a wider area than earlier devices and will be used in a third trial this year to aid decommissioning efforts.
- On Thursday, Tokyo Electric Power Company Holdings unveiled a 22-metre snake-like robot arm and released a four-minute video showing it moving through narrow passages.
- The 2011 tsunami and 9.0-magnitude earthquake left around 880 tonnes of hazardous material, and dangerously high radiation levels make removal a decades-long challenge.
- Developed by the International Research Institute for Nuclear Decommissioning since 2017, the 22-metre robotic arm weighs about 4.6 tons, is camera-equipped, remotely operated, and uses brush-like attachments to collect debris.
- TEPCO plans to begin setting up the arm next month and expects a third trial retrieval at the No.2 reactor this summer, while large-scale removal at the No.3 reactor is scheduled for fiscal 2037 or later.
- Only tiny samples have been collected twice so far and previous tools fetched 0.9 milligram each, highlighting the scale gap the robotic arm must overcome before full-fledged extractions.
