Tokyo Electric Power Co. on July 24 released a new video of a containment vessel at the No. 3 reactor of the ravaged Fukushima No. 1 Nuclear Power Plant.
The video was filmed by an underwater robot, which was sent into the reactor to study the condition of melted fuel debris. The four-minute long footage showed a large amount of lava-like lumps believed to be debris of melted fuel stuck to machines and building frameworks.
