Fukushima Daiichi Nuclear Power Plant “fuel debris” retrieval device released on July 2, 19:51
For the first time, a video of a robot arm with a total length of about 22 meters, which is being developed in the UK, was released for the purpose of taking out the so-called "fuel debris", a nuclear fuel that melted down due to the accident at the TEPCO Fukushima Daiichi Nuclear Power Station ..
The removal of the nuclear fuel, so-called "fuel debris", which has melted down from Units 1 to 3 of the Fukushima Daiichi Nuclear Power Plant, is the biggest challenge in decommissioning. I'm going to start.
On the 2nd, the video of the take-out device being developed in the UK was released for the first time.
At the center of the device is a robot arm with a length of about 22 meters and a weight of about 4.6 tons, which collects fuel debris by attaching it to the brush attached to the tip while remotely watching the camera image.
The video shows how the robot arm is stretched and shrunk, and how lead debris like fuel debris is attached to the brush.
The robot arm will be tested next month in the United Kingdom to simulate actual removal, and from February next year, it will be tested in Fukushima Prefecture for about four months.
