Melted fuel from Fukushima disaster still missing

Before officials can tackle the challenge of removing the melted fuel, they first have to find out where the nuclear waste is located. The radiation levels at the wreckage are too high for people to investigate. In an effort to find the missing waste, engineers have developed remote control robots to withstand the radiation levels.

Even remote control robots are insufficient to probe the crippled reactors. A robot probe quit working in three hours after it was sent into Fukushima’s No. 1 plant to collect radiation levels. The mission was intended to last ten hours. The probe was designed to withstand high radiation levels. No one knows exactly why the robot stopped working. Continue reading
