The Nuclear Regulatory Commission, which has resumed the investigation of the Fukushima Daiichi Nuclear Power Plant accident, will acquire and analyze the video of the moment when Unit 3 caused a hydrogen explosion. He is trying to elucidate the power of the explosion and how much hydrogen that caused it leaked.
At the Fukushima Daiichi Nuclear Power Plant Unit 3 of TEPCO, a nuclear fuel melted down and hydrogen was generated during the accident 9 years ago, and hydrogen was blown off, and the upper part of the building with the nuclear reactor was blown off.
The Nuclear Regulatory Commission, which has resumed the investigation of the cause of the accident, is proceeding with an investigation in December last year, such as by taking pictures of the walls and equipment that were severely broken inside the Unit 3.
Then, in order to investigate the situation of the explosion in more detail, I decided to obtain the footage of the explosion taken by a local TV station and analyze it.
The hydrogen explosion of Unit 3 is thought to have occurred near the top floor, and caused significant damage to the lower floors, but detailed analysis of the explosion has not been performed so far.
The regulatory committee wants to add experts on hydrogen and explosives, analyze the state of flames and blasts, and clarify the power of the explosion, how much hydrogen leaked from where, the timing and cause of ignition, etc. I am.
The Nuclear Regulatory Agency, which is the secretariat of the Regulatory Commission, said, "By examining the state of the explosion, the risk of hydrogen, which is extremely flammable, can be clarified more clearly. The survey results will also lead to safety measures for other nuclear power plants." I will.
