Fukushima Nuclear Plant reactor number 1 Daiichi facility is seen in Fukushima Prefecture, northeastern Japan, March 11, 2011. Japanese authorities battling to contain rising pressure in nuclear reactors damaged by a massive earthquake were forced to release radioactive steam from one plant on March 12, 2011 after evacuating tens of thousands of residents from the area. Tokyo Electric Power Co also said fuel may have been damaged by falling water levels at the Daiichi facility, one of its two nuclear power plants in Fukushima, some 240 km (150 miles) north of Tokyo.
