Overview
- A TEPCO video shows the 22-meter, 4.6-tonne arm navigating tight passages and inspecting complex structures inside confined spaces.
- The camera-equipped device is described by TEPCO as better at gathering information than earlier tools.
- TEPCO plans to use the new arm later this year for a third trial to retrieve debris from Reactor No. 2.
- Previous trials recovered only tiny samples—about 0.9 milligram per attempt—underscoring the limits of earlier equipment.
- An estimated 880 tonnes of hazardous fuel debris remain across three reactors, making debris retrieval the toughest phase of decommissioning.
