Melted fuel seen for first time at Fukushima plant

An underwater robot captured images of solidified lava-like rocks Thursday inside a damaged reactor at Japan's crippled Fukushima nuclear plant, spotting for the first time what is believed to be nuclear fuel that melted six years ago. Plant operator Tokyo Electric Power Co. said the robot found large amounts of lava-like debris apparently containing fuel that had flowed out of the core into the primary containment vessel of the Unit 3 reactor at Fukushima. The plant was destroyed by a massive earthquake and tsunami in March 2011. This image captured by an underwater robot shows lava-like lumps believed to contain melted fuel inside the Unit 3 reactor at Fukushima. Experts believe the fuel melted and much of it fell to the chamber's bottom and is now submerged by radioactive water.
