But this does not mean Fukushima is now on a par with Chernobyl. Indeed, as Bloomberg notes, the data so far suggests that Fukushima has released only one-tenth as much radioactive material as Chernobyl did.

It's also important to note that the upgrading does not mean that the situation is getting worse. Rather, it is a reassessment of what has already happened. The largest releases of radioactive material occurred in the first days after the earthquake, and the amount released every day has generally been decreasing as various leaks have been plugged.

One way of looking at the drama that has unfolded around the Fukushima Daiichi nuclear reactors is as a narrative with one central plot, and a number of sub-plots distracting the attention.

A new analysis of wind energy supplied to the UK National Grid in recent years has shown that wind farms produce significantly less electricity than had been thought, and that they cause more problems for the Grid than had been believed.

Japan has been asking foreign media to objectively report on the evolving crisis at the Fukushima Daiichi nuclear power plant, the Foreign Ministry said Thursday, as reports deemed sensationalist or based on incorrect information have fanned concern and led to import restrictions on Japanese products.

State Foreign Secretary Chiaki Takahashi told a press conference that Tokyo believes some reports by foreign media on the Fukushima crisis were ''excessive'' and has urged the organizations responsible for the stories through Japanese diplomatic missions abroad to correctly and objectively disseminate information.

Ministry officials said some foreign media, including tabloids, emphasized the danger of radioactive materials leaking from the Fukushima nuclear plant by focusing on extreme projections, while erroneously reporting that the plant operator Tokyo Electric Power Co. has hired homeless people to tackle the ongoing crisis.

In this article, that for some reason mostly focuses on the bleeding obvious -- that Tepco are not going to be able to use reactors 1 through 4 at Fukushima Daiichi -- there is also this:

There has been some public mistrust regarding the official data, with fears exacerbated by occasionally contradictory announcements. But Jan van de Putte, a Greenpeace official, said Wednesday that its scientists’ findings largely correlated with the official Japanese data.

“There is no contradiction between Greenpeace data and local data,” he said. “The contradiction is between the data, and action to help people” in the affected areas.

Japanese engineers are struggling to gain control of the Fukushima Daiichi nuclear power plant, 240 km (150 miles) north of Tokyo, which was seriously damaged by a March 11 earthquake and tsunami.

Two of the six reactors at the plant, operated by Tokyo Electric Power Co (TEPCO), are considered stable but the other four are volatile.

Following are some questions and answers about efforts to end the world's worst nuclear crisis since the 1986 Chernobyl accident:

This is an unusually levelheaded analysis of the situation, especially compared to all the hysterical handwaving we have seen in Western mainstream media lately.

More than 10,000 people have died in the Japanese tsunami and the survivors are cold and hungry. But the media concentrate on nuclear radiation from which no-one has died - and is unlikely to.

Worst of all, the reporting has put the focus entirely on the Fukushima nuclear plant. As worrisome as the issue is, it has been completely blown out of proportion, with talk of meltdown and massive destruction. The tragedy is that the victims of the earthquake and tsunami are all but forgotten at times. While the world turns away to ponder its own nuclear policies — which, for better or for worse, are far from urgent — people are starving and dying after having survived the disaster itself.

The nuclear plant story is exciting and dramatic and is easy to exaggerate, but it will quickly wear thin as the plant cools and the international public realizes that the fears were deliberately whipped up. By then, it could be far too late for many survivors.

A top official at Japan's nuclear-safety regulatory agency sees no slowing in the country's campaign to expand atomic power, despite the battle to contain the world's worst nuclear crisis in 25 years, saying in an interview that the alternative is "blackouts."

"There aren't that many easy alternatives available for us," said Hidehiko Nishiyama, a former trade negotiator tapped to help deal with the Fukushima nuclear crisis, on Wednesday. "Japan couldn't go forward without nuclear power in order to meet its demand for energy today," he said. About 30% of Japan's electricity output comes from nuclear, and the government has set the goal of increasing that to 40% by 2020.
