New images from a robot probe inside the Fukushima reactor have sparked nuclear meltdown fears.
Photographs captured inside one of the three melted reactors at the tsunami-wrecked Fukushima nuclear power plant showed exposed steel bars and parts of its thick external concrete wall missing, triggering concerns about its earthquake resistance in case of another major disaster.
The plant's operator, Tokyo Electric Power Company Holdings, has been sending robotic probes inside the Unit 1 primary containment chamber since last year. The new findings released Tuesday were from the latest probe conducted at the end of March.
