Fukushima Daiichi reactors internal estimates by Tepco
In dismantling the Fukushima Daiichi nuclear power plant, it is essential to grasp the state of nuclear fuel melted its nuclear reactors, but the radiation is very high and it is difficult to see inside. Under these circumstances, TEPCO announced a new estimate chart for the interior of the three nuclear reactors.
TEPCO announced the estimate inside the nuclear reactors at the International Forum on Waste Plant on the July 3rd, 2017. In the inside of the nuclear reactor of Unit 3, a part of the nuclear fuel collapsed to the bottom of the pressure vessel and is stacked like a garbage while keeping its shape. Meanwhile, it seems that molten nuclear fuel has fallen to the bottom of the storage container beneath, but when analyzing the data at the time of the accident again, it is said that there is a possibility that it is eroding the concrete on the floor of the containment vessel .
Estimates were obtained reflecting computer simulations and recent internal surveys, etc. Based on these estimates, the government decided how to remove “fuel debris”.

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!”
