Following up this article..Tepco released video of emergency TV meeting “99.3% cut off, 1665 beep sounds, 29 image concealment”
There have been comments posted on Fukushima Diary that Tepco and Japanese government should have blasted Fukushima plant.
Tepco actually considered blasting the reactor building before the explosion of reactor3.
The conversation was found from the 150 hours of the video, which is concealed from us. 99.3% of the video is only available for the mass media. (cf. Tepco executives disappeared from emergency headquarters after the explosion of reactor1)
From 14:00 of 3/13/2011, Tepco’s head office and Fukushima plant were discussing the countermeasures for the risk of reactor3 explosion. It was presumed that hydrogen gas concentration was increasing inside of the reactor building.
An employee at Fukushima site offered to make a hole by dropping something from helicopter since blowout panel can’t be opened and no one can approach it. It is banned to disclose the name of this staff recorded in the video. Regardless of the risk of explosion, the chief of Kashiwazaki Kariwa nuclear plant agreed to this idea depending on the wind direction.
At the same time, head office of Tepco offered more risky idea to blast the panel of the reactor building by having self-defense force use firearms from sea side.
After all, this offer was declined because sparks may cause explosion and there are important equipments in reactor3 building.
Prof. Unesaki from Kyoto University Research Reactor Institute assumes that they thought self-defense force might be injured by conducting those countermeasures, so they did not blast the reactor buildings.
