Who are the "Fukushima 50" -- the workers trying to take regain control of Japan's stricken Fukushima Daiichi nuclear power plant? Twitter messages and blog posts by the workers' families offer an inkling of the "Fukushima 50," so nicknamed because the 180 employees at the site work in 50-person shifts. One of the workers is a veteran power plant worker, a 59-year-old who volunteered to take on the assignment, according to Jiji Press, a Japanese news wire service, quoting a woman who claimed to be his daughter on Twitter.

[Update 12:47 a.m.] Tokyo's utility company says black smoke has been seen emerging from Unit 3 of the crippled nuclear plant in northeastern Japan, prompting a new evacuation of the complex. Officials with Tokyo Electric Power Co. said Wednesday that workers from the entire Fukushima Dai-ichi plant have been temporarily evacuated. _________________ Control room lights were on and electronic thermometers were functioning Wednesday at several of Japan's stricken nuclear reactors, marking small but potentially critical steps toward controlling overheated fuel that has been spewing radiation for more than a week.

The fuel rods at a third nuclear reactor at the Fukushima No. 1 nuclear power plant have been fully exposed to air for short periods of time and at least partially exposed for more than three hours, allowing them to heat up and sharply raising the risk of a meltdown, according to officials of the Tokyo Electric Power Co., which owns the plant. The cooling problems at reactor No. 2 represent the most serious development in the ongoing problems at the nuclear power plant to date, according to nuclear specialist Edwin Lyman of the Union of Concerned Scientists.

Japanese nuclear regulatory officials Tuesday raised the severity rating at the earthquake- and tsunami-damaged Fukushima Daiichi power plant to the highest level by international standards, equaling the 1986 Chernobyl meltdown in the former Soviet Union. The country's Nuclear and Industrial Safety Agency announced that because of the amount of radioactive material released from the plant after the magnitude 9 earthquake a month ago, the rating would be changed to level 7, a "major accident" on the International Atomic Energy Agency's scale, up from a level 5, an "accident with wider consequences.

As Japan marked two weeks since the giant earthquake and tsunami, the number of people dead or missing grew to more than 27,000, with at least 200,000 others in shelters and radioactivity from a stricken nuclear plant continuing to cast a pall over daily life. Two workers at the hobbled Fukushima Daiichi nuclear facility were hospitalized for radiation exposure Thursday after stepping into contaminated water during repair operations at reactor No. 3, officials at the nation's nuclear safety agency said.

For the better part of Sunday, media outlets in Japan and around the world carried scary-sounding news about radiation at the stricken Fukushima nuclear plant's No. 2 reactor. In a typical report, Japanese broadcaster NHK said: "Power company says it has detected radioactive materials 10 million times normal levels. " After nightfall came the mea culpa. There was a "mistake in the measurement of the assessment" of radiation in a building near the reactor, Tokyo Electric Power Co. said on its website.

Hajime Shiraishi's moment of truth came when her online video news show, at the time relatively unknown, decided to buck the government line and call a story as it saw it. On March 11, after an earthquake-driven tsunami damaged the Fukushima Daiichi nuclear power plant, the world waited anxiously to see how its fragile reactors would fare. Later that day, plant operator Tokyo Electric Power Co., or Tepco, announced on national TV that all was well: The utility was on top of the accident.

They sleep with just one blanket apiece anywhere there's space — in a conference room, in the hallway, near the bathroom. Because deliveries of supplies are limited, they get by on very little food: Breakfast is packages of high-calorie emergency crackers and a small carton of vegetable juice; dinner consists of a small bag of "magic rice" (just add bottled water) and a can of chicken, mackerel or curry. There is no lunch — handing out a noontime meal would be too complicated in the crowded two-story building.

The little robot rumbled across an otherworldly landscape, its camera lens clouding up in a hostile atmosphere too toxic for human habitation. Its motor whirring, it dispatched a constant stream of images to nervous operators grouped a safe distance away. But the setting wasn't Mars and the scientists aren't from NASA: The robot's handlers were Japanese engineers guiding the remote-controlled machine through one of the battered reactors at the Fukushima Daiichi nuclear power plant.

Although officials of the U.S. Nuclear Regulatory Commission said Monday that conditions at the Fukushima Daiichi nuclear power plant appear to have stabilized and that the containment vessels at three reactors had not been seriously breached, smoke was reported rising from two reactors Monday evening. The cause of the smoke was unknown, however, and it did not appear to be associated with a radiation spike. The executive director of the NRC, Bill Borchardt, said Monday that the agency's staff in Japan reported that the three reactors that had shut down following the magnitude 9.0 Tohoku earthquake 10 days ago probably have suffered some core damage but do not appear to be leaking significant quantities of radiation.
