Robot Finds Likely Melted Fuel Heap Inside Fukushima Reactor

This image captured by an underwater robot provided by International Research Institute for Nuclear Decommissioning on Saturday, July 22, 2017 shows massive deposits believed to be melted nuclear fuel covering the floor of a damaged reactor at Japan's crippled Fukushima nuclear plant in Okuma town, northeastern Japan. The robot found large amounts of solidified lava-like rocks and lumps in layers as thick as 1 meter (3 feet) on the bottom inside of a main structure called the pedestal that sits underneath the core inside the primary containment vessel of Fukushima's Unit 3 reactor, said the plant's operator, Tokyo Electric Power Co.
