Japan TV dioramas of stricken Fukushima nuclear plant are dissonantly adorable (screengrabs from NHK, courtesy IZ RELOADED) During a live broadcast yesterday, the Japanese television network NHK unveiled a hand-crafted scale model of the damaged Fukishima Daiichi nuclear plant. Like the cardboard infographics their nuclear experts have been pointing to on-air since the nuclear crisis began, this diorama is a key part of their news presentation, a visual aid of sorts. There is nothing cute or cool about the multiple disasters that have struck Japan: the earthquake and tsunami have already claimed at least 5,000 lives and perhaps many more; tens of thousands are already known to be missing or displaced. The still-unfolding nuclear accident is serious, and could have grave consequences for Japan. Japan TV dioramas of stricken Fukushima nuclear plant are dissonantly adorable
Radiation reached around 20 times normal levels in the capital Tuesday morning, the Tokyo Metropolitan Government said, while offering the assurance this reading posed no immediate risk to human health and that the public should remain calm.

LONDON/DETROIT (Reuters) - The growing risk of a significant radiation leak at two Japanese nuclear power plants following Friday's earthquake and tsunami threatens to hurt an industry that has enjoyed a rebirth since the Three Mile Island accident in 1979 and the Chernobyl disaster in 1986. On Friday, nuclear power advocates and environmentalists staked out familiar ground over the incident. But a wider public debate may be ignited if a major radiation leak occurs in Japan, said Paul Patterson, an energy analyst with consultants Glenrock Associates in New York. That debate has been largely muted since the 1980s when rock concerts were held to galvanize opposition to nuclear power after the Three Mile Island incident in Pennsylvania and the popular movie "The China Syndrome," that raised awareness of the dangers of a nuclear reactor meltdown.

Russian nuclear authorities said a Chernobyl-type disaster was unlikely to happen at the stricken nuclear plant in Japan, but experts refused to rule out this scenario. “There can be no replay of Chernobyl at the Fukushima nuclear plant,” said Sergei Novikov, official spokesman for the Russian nuclear corporation Rosatom. “The worst case scenario in Japan is what happened at the Three Mile Island nuclear plant in the U.S. in 1979, where fuel melted down but stayed inside the reactor.” International : Russian experts on Chernobyl scenario in Japan International : Russian experts on Chernobyl scenario in Japan

[UPDATE: 5:59 PM ET: The evacuation zone around the power plant has been increased to 10 km, or 6.2 mi.] [UPDATE: 5:46 PM EST: Japanese authorities announced that radiation inside the stricken Fukushima power plant control room has risen to 1,000 times its normal level. Some has leaked outside of the plant, prompting calls for further evacuations beyond the 3,000 people who have been cleared out already in a 1.8-mi. radius.

Water injected into Fukushima reactor Authorities scrambled Sunday to control an overheating reactor at the problem-prone Fukushima No. 1 nuclear power plant by injecting seawater and venting gas to reduce the pressure inside. While acknowledging that the core of the plant’s No. 3 reactor may have overheated and deformed, Chief Cabinet Secretary Yukio Edano denied it led to a meltdown of the critical fuel rods. At a news conference, Edano said that “a very small amount” of radioactive substances had leaked from the No. 3 reactor, dismissing concerns it posed a threat to human health. The government’s top spokesman warned, however, that a hydrogen explosion similar to the one that blew up a building housing a separate reactor at the facility Saturday could occur again at this reactor. Large amounts of hydrogen formed when the water injection procedure temporarily ran into trouble and may have filled the upper part of the building housing the No. 3 reactor, Edano said.

Japanese authorities began evacuating more than 200,000 people Saturday from areas around two nuclear power plants after an explosion at one of them damaged a building housing an aging U.S.-supplied reactor. The unit, built 40 years ago by General Electric, is one of as many as seven reactors imperiled by the earthquake and subsequent disruptions in the power supply that the reactors use for cooling systems. One nuclear worker was killed, at least six were injured and two were missing at the plants in the aftermath of Friday's 8.9 magnitude earthquake and the blast Saturday afternoon, according to the Tokyo Electric Power Co., which operates the Fukushima I and II nuclear power stations. The company said it was taking steps to relieve pressure that has built up in seven of the plants' 10 reactor containment vessels. It said this would be done through a "partial discharge of air containing radioactive materials."
