Meltdown fears rise after rods at Japanese nuclear reactor partially exposed

TOKYO - A Japanese utility says fuel rods at a troubled nuclear reactor were once again fully exposed hours after authorities were able to stabilize a similar emergency.

Tokyo Electric Power Co. Says the exposure happened at Unit 2 of the Fukushima Dai-ichi plant because a steam vent wouldn't open Monday, causing a sudden drop of water.

That reactor and two others at the plant are dangerously overheating and authorities are racing to prevent meltdown.

The Japanese government warned that three nuclear reactors at the Fukushima No. 1 power plant were "highly likely" to face meltdown, the Kyodo News agency reported Monday.

With more than 70 nations or regions offering aid, the aircraft carrier USS Ronald Reagan arrived off the Japanese coast early Sunday.

But the aircraft carrier was forced to change position Monday after detecting a radioactive cloud.

Three US helicopters flying missions about 60 miles north of the damaged reactors also became coated with particulate radiation that had to be washed off.
