The investigation inside the containment vessel of Fukushima Daiichi Nuclear Power Station Unit 1 has been resumed for the first time in about half a year. I'm going to investigate more about the sediments that are likely to be .

From February to June this year, TEPCO will introduce three types of robots into Unit 1 of the Fukushima Daiichi Nuclear Power Plant to photograph the inside of the containment vessel and measure deposits that are likely to be "fuel debris". is being implemented.



TEPCO resumed the survey after about half a year, and on the morning of the 6th, put an underwater robot inside the containment vessel for the purpose of grasping the state of the sediment in detail.



From the 6th to the 4th, we plan to measure radiation levels at eight locations inside the robot using sensors attached to the robot, and we would like to determine whether the deposits are "fuel debris."



In addition, in March next year, we will try to shoot with a camera inside the "pedestal" structure that supports the nuclear reactor, which has not been investigated so far.



TEPCO hopes to obtain important clues that will lead to the retrieval of "fuel debris" by introducing a total of four types of underwater robots. It will be interesting to see if the results are good.
