Tokyo Electric Power Company has released an image taken by a drone of the situation directly below the reactor at Unit 1 of the Fukushima Daiichi Nuclear Power Plant. The image shows for the first time that icicle-like objects that may contain melted "nuclear fuel debris" are attached to equipment that fell from the bottom of the reactor.
TEPCO plans to analyze these images in more detail and use them to consider methods for removing debris. Based on previous studies and simulations, it is estimated that the amount of nuclear fuel debris is approximately 880 tons from Units 1 to 3.
