Two weeks after the nuclear disaster started, at the Fukushima Daiichi nuclear plant, the Japanese Atomic Energy Commission submitted a worst case scenario to the government.
It could have been (and might still be) worse than the atomic bombings of Hiroshima and Nagasaki.
The official reason why the report was not made public, is because government officials did not consider it an official document! The real reason is that the report was quickly dismissed by officials, and then forgotten, until it was discovered in an office of the Atomic Energy Commission, at the end of 2011.
Currently there is a 20 km (12 miles) mandatory evacuation zone around Fukushima Daiichi, some experts say it should be expanded. Under the worst case scenario it should be 170 km (105.6 miles)!
The scenario also called for voluntary evacuations out to 250 kilometers (155 miles). That would include all of Tokyo!
The nuclear reactors are considered in cold shut down, but they are far from stable. Currently, Reactor 2 keeps heating up and Tokyo Electric Power Company officials don’t know why!
