The nuclear crisis in Japan grew more troubling Sunday as efforts to control the Fukushimi Daiichi nuclear power facility continued to hit unexpected roadblocks. But Energy Secretary Steven Chu says Americans "are in no danger" from radiation.
The most dangerous of Japan’s stricken nuclear reactors at the Fukushima Daiichi nuclear power plant appeared to stabilize Saturday, according to Japanes authorities.
Japan pours tons of water into a reactor building where the water level in a cooling pool for spent fuel rods was dangerously low. The nuclear crisis is now rated as severe as Three Mile Island.
Fukushima fire: The fire that began on Tuesday has led to extreme radiation leaks that have forced officials to withdraw all crews from the nuclear plant. The Fukushima fire can not be confirmed to still be burning in the now-unmanned plant.
A month after the March 11, a 9.0 earthquake triggered a 30-foot tsunami that damaged several nuclear reactors in northeastern Japan, causing the country's worst crisis since World War II, a 7.4 temblor shook the country again.
Fifty workers and fire hoses are all that remain at Japan's Fukushima I plant to cool three hot reactors and six pools containing spent fuel rods – perhaps for months to come.
Japan officials told the International Atomic Energy Agency (IAEA) that 'radioactivity is being released directly into the atmosphere' after a fire broke out in a storage pond for spent fuel at nuclear reactor damaged by Friday's earthquake and tsunami.
Radiation exposure: Adding to the monumental losses after a Japanese earthquake and tsunami, problems at four nuclear reactors have residents near and far concerned about radiation exposure.
Scientists warn of risks from spent-fuel cooling pools and plutonium-rich, mixed-oxide fuel inside one nuclear reactor, even as the No. 1 and No. 3 reactors appear to be coming under control.
Japanese workers raced against the clock to pump seawater into two damaged nuclear reactors. It’s a last-ditch effort to cool them enough to avert the kind of core meltdowns that happened at Chernobyl and Three Mile Island.
