A strong aftershock struck off the coast of northeast Japan on Monday as the Japanese government said it was preparing to expand the evacuation zone around a crippled nuclear power plant to address concerns over long-term exposure to radiation.

Japan's troubled effort to contain the nuclear contamination crisis at its stricken Fukushima Daiichi plant suffered a setback on Sunday when alarmingly high radiation levels were discovered in a flooded area inside the complex, raising new questions about how and when recovery workers could resume their tasks.Tokyo Electric Power Company, the oper...

Japanese officials continued to battle a spreading contamination problem at the Fukushima nuclear complex on Sunday, saying that water pooling inside one of its reactors and the seawater just outside the plant were showing sharply increased levels of radiation. The Nuclear and Industrial Safety Agency said that water seeping out of the crippled No....

Japanese officials began encouraging people to evacuate a larger swath of territory around the Fukushima Daiichi nuclear plant on Friday as new signs emerged that parts of the crippled facility are so damaged and contaminated that it will be hard to bring the plant under control soon. The authorities said that they would now assist people who want ...

Japan's nuclear crisis intensified again on Wednesday, with Japanese authorities announcing that a containment vessel in a second reactor unit at the stricken Fukushima Daiichi plant in northeastern Japan may have ruptured and appeared to be releasing radioactive steam. That would be the second vessel to be compromised in two days. The vessel had a...

A small crew of technicians, braving radiation and fire, became the only people remaining at the Fukushima Daiichi Nuclear Power Station on Tuesday -- and perhaps Japan's last chance of preventing a broader nuclear catastrophe.They crawl through labyrinths of equipment in utter darkness pierced only by their flashlights, listening for periodic expl...

The company that runs the troubled Fukushima Daiichi plant in northeastern Japan announced on Wednesday that a fire was burning there, just hours after officials said flames that erupted on Tuesday had been doused. (In Pics: Japan earthquake triggers tsunami)Soon after that announcement, a government official at Japan's nuclear watchdog agency said...

Japan's nuclear crisis verged toward catastrophe on Tuesday after an explosion damaged the vessel containing the nuclear core at one reactor and a fire at another spewed large amounts of radioactive material into the air, according to statements from Japanese government and industry officials.In a brief morning address to the nation Tokyo time, Pri...
