Japan nuclear meltdown 'maybe worse than thought'Let's review. The 2011 Tohoku earthquake and tsunami had a 9.0 earthquake, one of the five biggest ever recorded anywhere in the world. Waves were 130 feet high, and reached 6 miles inland. 16,000 people were killed.
Tokyo Electric Power (TEPCO) said their latest calculations showed the fuel inside the No. 1 reactor at the tsunami-hit plant could have melted entirely, dropping through its inner casing and eroding a concrete base.
In the worst-case scenario, the molten fuel could have reached as far as 65 centimetres (2 feet) through the concrete, leaving it only 37 centimetres short of the outer steel casing, the report, released Wednesday, said. ...
The world's worst nuclear disaster since Chernobyl in 1986 has not directly claimed any lives, but has left tens of thousands of people displaced and rendered tracts of land uninhabitable, possibly for decades.
TEPCO and the Japanese government have pledged to bring all the plant's reactors to a state of cold shutdown by the end of 2011.
Some nuclear reactors were hit. They were very old plants and used obsolete designs that the world abandoned as unsafe in 1970. The Japan authorities responded poorly, and there was a nuclear meltdown. They were not prepared for a disaster of this magnitude.
Now the experts say that the Japan nuclear meltdown was maybe worse than thought because a computer simulation shows that molten nuclear fuel at the most damaged plant might have eaten two thirds of the way through a concrete containment base. But no one died and a cold shutdown is imminent.
Nuclear power is clean and safe, and is the only technology for producing large-scale power without emitting greenhouse gases. Some of the global warming alarmists admit this. The others must not be serious about global warming, because they are unwilling to take the steps to produce carbon-free energy.
