"Crucial efforts to tame Japan's crippled nuclear plant were delayed by concerns over damaging valuable power assets and by initial passivity on the part of the government, people familiar with the situation said, offering new insight into the management of the crisis."

"The chairman of the Nuclear Regulatory Commission said Sunday morning that the spent fuel pools at American nuclear reactors are less vulnerable than the ones in Japan because of steps ordered by his agency after the attacks of Sept. 11, 2001, including having utilities prepare to use fire hoses to pump in extra water in the event ordinary cooling systems are knocked out."

"Operators evacuated workers from Japan's tsunami-damaged nuclear plant Monday after gray smoke rose from one of its reactor units, the latest of persistent troubles in stabilizing the radiation-leaking complex."

"The Nuclear Regulatory Commission failed to resolve known safety problems, leading to 14 'near-misses' in US nuclear power plants in 2009 and 2010, according to a new report from a nuclear watchdog group."

"After a week of disasters and setbacks, power plant workers and military personnel at the Fukushima Dai-ichi power plant made some progress today in cooling over-heated fuel rods."

"The Japanese government has said the nuclear plant ravaged by the tsunami will be closed once its overheating reactors are brought under control."

"TOKYO — The government said Saturday that it had found higher than normal levels of radioactive materials in spinach and milk at farms up to 90 miles away from the ravaged nuclear power plants, the first confirmation by officials that the unfolding nuclear crisis has affected the nation’s food supply."

"Two outlets today nailed issues raised by the behavior of Japan’s government leaders and the utility company whose Fukushima Deiichi power station is suffering multiple losses of control and breached containment, and the behavior of many and perhaps most media in trying to tell the story, warn the public, and stay within the bounds of reason."

"New worries about a New York nuclear plant's vulnerability to earthquakes could hand the state's governor an opportunity to try to close the plant, but New York City's huge power needs could stall any such moves."

"Japanese engineers battled on Friday to cool spent fuel rods and restore electric power to pumps at the stricken Fukushima Daiichi Nuclear Power Station as new challenges seemed to accumulate by the hour, with steam billowing from one reactor and damage at another apparently making it difficult to lower temperatures."
