A remote-controlled robot has safely returned with a tiny piece of melted fuel it collected from inside one of three damaged reactors at the tsunami-hit Fukushima Daiichi nuclear power plant for the first time since the 2011 meltdown.
The Tokyo Electric Power Company Holdings, which manages the plant, said Saturday that the extendable fishing rod-like robot successfully clipped a gravel as big as 5 millimeters (2 inches), the size of a tiny granola bit, from the top surface of a mound of molten fuel debris that sits on the bottom of the No. 2 reactor’s primary containment vessel.
