Fukushima Daiichi Nuclear Power Plant Unit 3 Explosion Analyzed Multiple Times Video Nuclear Regulatory Commission November 13 6:03
The Nuclear Regulatory Commission, which is investigating the cause of the accident at the Fukushima Daiichi Nuclear Power Station, said that the explosion occurred multiple times as a result of detailed analysis of the video of the moment of the explosion of Unit 3 that caused the hydrogen explosion. Was shown again.
In the accident at TEPCO's Fukushima Daiichi nuclear power plant that caused a meltdown, hydrogen explosions occurred in three reactor buildings and the buildings were severely destroyed.
The Nuclear Regulatory Commission, which resumed investigations into the causes of the accident last year, analyzed the images taken at Unit 3 with experts on the 12th.
As a result, it seems that the wind pressure of up to about 5 atm was momentarily applied to the beam from the degree of bending of the ceiling beam on the 3rd floor.
This wind pressure has the power to damage concrete and collapse wooden buildings.
In addition, as a result of image processing and analysis of the image of the TV station in Fukushima Prefecture, which was the only one that could shoot the explosion of Unit 3, he reiterated the view that the explosion had occurred multiple times, and the first explosion broke the 4th floor, then He explained that a fire broke out on the 5th floor of the top floor, the remaining hydrogen exploded, and black smoke rose.
The Regulatory Commission plans to finalize the draft report next month.
