Fukushima Daiichi Nuclear Power Plant Unit 3 Hydrogen Explosion May Occur Multiple Times For Detailed Verification At 6:39 on September 4


The Nuclear Regulatory Commission, which is investigating the accident at the Fukushima Daiichi Nuclear Power Station, indicated that there may have been multiple explosions of Unit 3 that caused a hydrogen explosion, and will examine it in detail in the future. became.

At the TEPCO Fukushima Daiichi Nuclear Power Plant, when the accident occurred nine and a half years ago, the nuclear fuel in the reactor melted down and hydrogen was generated, causing hydrogen explosions at Units 1 and 3 and a major building damage.

The Nuclear Regulatory Commission, which resumed the investigation of the cause of the accident last autumn, discussed Unit 3 on the 3rd, and from the investigation inside the building and the analysis of the images of the explosions conducted so far, it was said that there was only one explosion. Unlike the 1st machine seen, it was said that the 3rd machine may have occurred multiple times.

It is highly probable that the explosion occurred on the 5th and 4th floors of the top floor due to the damage to the walls, ceiling and beams inside the building.

In the future, the Regulatory Committee will continue to verify the explosion, such as the amount of hydrogen generated and the timing of ignition, and hope to use it as a safety measure for other nuclear power plants.
