A melted-down reactor in the Fukushima nuclear power station resting precariously on corroded supports could be toppled over by a strong earthquake, new photos have revealed.
The images, which were taken by a robot, showed the reactor was resting unsteadily on a fragile frame of corroded supports.
While the interior of the damaged Dai-ichi reactors in Japan was too radioactive for humans to enter safely, a remote-controlled robotic camera has sent back pictures from reactor No 1.
