In a case of hear no evil, see no evil and speak no evil, a Japanese government investigation into the corporate mind of Tokyo Electric Power Company revealed that officials just couldn’t believe the worse case scenario could happen at Fukushima Daiichi.
TEPCo officials admitted that they discussed the possibility of explosions inside the reactor buildings, but dismissed the possibility as unlikely.
Then, just one day after the 11 March 2011 quake/tsunami, Reactor 1 exploded. TEPCo officials were focused so much on other concerns, that it took the second explosion, in Reactor 3 on 14 March, to wake them up.
Some government officials conclude that Tokyo Electric officials don’t realize just how dangerous a nuclear reactor can be.
