Japan’s nuclear regulator maintains view on Fukushima Daiichi’s No.3 reactor blasts
November 13, 2020
Japan’s nuclear regulator has maintained its view that multiple blasts occurred at the Fukushima Daiichi nuclear power plant’s No.3 reactor following the earthquake and tsunami in 2011.
The plant suffered meltdowns from the accident. Three reactor buildings were severely damaged by hydrogen explosions.
On Thursday, the Nuclear Regulation Authority along with experts analyzed images taken at the No.3 reactor.
Officials say the state of buckled beams on the third floor indicates an instantaneous wind pressure of up to 5 atmospheres. The officials say such force can damage concrete structures and collapse wooden buildings.
They also studied the only footage of the No.3 reactor in the explosion, which was captured by a TV station in Fukushima Prefecture.
The officials say an analysis of image processing shows the first blast damaged the fourth floor. They say an ensuing fire on the uppermost fifth floor caused the remaining hydrogen to explode, which caused black smoke to emerge.
The regulator resumed its probe into the cause of the accident last year. It plans to draw up a report as early as next month.

Tsuboi released comments expressing his joy after he
learned that the Treaty on the Prohibition of Nuclear
Weapons would enter in force.
“I am filled with excitement, thinking, ‘At long last.
This is great.’ It is a major step toward my long-held,
earnest desire for nuclear weapons to be banned
and eliminated,” he said. At the same time, he
noted that states with nuclear weapons, as well
as Japan, had not ratified the treaty and said, “The road hereafter may be rough.”
Still, each time I have met Tsuboi, he has
repeatedly stated, “I won’t give up until there ar
e zero nuclear weapons. Never give up!”
