BBC said:2249: Officials said the fire new erupted, or reignited, because a blaze at the plant earlier had not been extinguished.
BBC said:2327: Minoru Ogoda, a spokesman for the Japanese nuclear safety agency, tells AFP: "We have received information from [the Tokyo Electric Power Company] that the fire and smoke is now invisible and it appears to have gone out of its own accord."
Bang Goes the Theory - Series 4 - Episode 1
The team looks at the science behind the recent Japanese earthquake and the tsunami it triggered. Plus the technology that attempts to protect us from the power of our planet.

To understand what a nuclear meltdown is I searched the internet to find the answers where I discovered this excellent document http://wapedia.mobi/en/Nuclear_meltdown.
Flames were no longer visible after about 30 minutes, however, said TEPCO, the plant operator, adding that it is considering spraying boric acid by helicopter to prevent the reactor's spent nuclear fuel rods from reaching criticality again, restarting a chain reaction.
''The possibility of recriticality is not zero,'' TEPCO said Wednesday as it announced the envisaged step to control the situation.
I'm really becoming very concerned about the meltdown currently occuring and i think everyone is estimating the danger. Levels of exageration and politically motivated hysteria are reaching critical mass accross the media in the london area. There is a serious danger that the dramatic and sudden increase in the levels of misplaced self rightousness and pompousity will result in a chain reaction that will be unstoppable and lead to a huge explosion of ingorance that will spread throughout the entire country.
Mobs made up of crazed members of the public will descend on nuclear power stations around the country bearing flaming torches like the villagers from hammer horror dracula and frankenstein films and demand that each power station be torn down and replaced by a single casio solar powered pocket calculator from the mid 1980's and one of those 12 inch tall plastic windmills like the ones you used to get from the seaside when you went on a day trip. Both these devices will be wired up to the national grid to provide a green, sustainable, cardon freindly (please feel free to insert the meaningless buzz word of your choice here) source of energy.
It will also avert the very real threat of giant slugs, mutated by nuclear radiation so that they have grown to the size of houses, rampaging (very slowly) through our cities, terrorising the population and eating all the lettuce in tesco's so there is none left for us.
Compared to the minor side issues of towns wiped off the map and thousands missing, focusing on the temperature of a nuclear reactor is whats really important and doesnt show any media bias or prejudice on an issue of contention whatsoever.
Really? Do you have a source for that?
"The workers suspended further operations and evacuated."
fuck - never before have I hoped more that CNN have got it wrong...
edit: btw my mate's in Tokyo so I'm not just avidly following this for nothing....
It is clearly a serious situation now because there is no containment for those spent fuel pools… My feeling is that they are probably a more serious issue now than the reactors, [where] there's at least a degree of containment remaining.
Spent fuel rods are strongly radioactive and the water above them shields against that radiation so as long as the water level is sufficiently high – you can walk up to the edge of the pool and pour a bucket of water in. Once it is even close to the top of the rods the levels are too high to approach the pool, which is clearly what has happened in unit 4.
Kyodo news has a slightly worrying update, in a breaking news item on its website – the military helicopters seen over the Fukushima nuclear plant (8.06am) have been unable to drop any water "due to high radiation".
3 looked in a bad state in that picture, and 4 also in worse state than previously described. I went and found latest satellite images and they confirm this rather clearly. Also note the small hole in number 2 & associated smoke/vapour release from the area - I suppose they may have done this deliberately to allow release. Also possible that 2 and 4 are located in opposite locations to what I am assuming. It still seems possible to me that some vapour has been escaping number 3 ever since it exploded, but a days gap in satellite & tv images makes it impossible to be sure.
Japan's science ministry has observed radiation levels of up to 0.33 millisieverts per hour in areas about 20 kilometers northwest of the quake-damaged Fukushima Daiichi nuclear power plant.
Experts say exposure to such radiation for 3 hours would result in absorption of 1 millisievert, or the maximum considered safe for 1 year.
The ministry gauged radiation levels for 10 minutes from 8:40 PM local time on Tuesday at 3 places in Fukushima Prefecture, whose residents are being instructed to stay indoors. The measurements produced readings as low as 0.22 millisieverts per hour.
It is not known whether these levels have changed since the measurements.
A former chief of the Radiation Effects Research Foundation, Shigenobu Nagataki, said radiation at such levels does not immediately affect human health. But he said that if such levels continue to be observed, authorities must review ways to evacuate people.
The ministry said it also observed maximum radiation levels of 0.0253 millisieverts in areas 30 to 60 kilometers from the plant on Wednesday morning. The levels are slightly higher than normal.
What amazes me is that they built a reactor on the coast with a massive faultline just off shore and didnt think to check that in the event of a tsunami that the diesel generator pumps would be operable. I mean seirously - that's gross negligence unless other factors come to light that excuse the reason why this didnt work properly.
Build them off ground, build them in a sealed watertight container - do something but dont build them on ground level off the shore knowing flooding would affect them.
