On board with the story:
Japan Reactor-Core Damage Is Worse Than Expected, Delaying Tepco’s Cleanup (Bloomberg, May 12)
Tokyo Electric Power Co. said one of the reactor cores at its stricken Fukushima Dai-Ichi nuclear plant is more seriously damaged than previously thought, setting back the utility’s plan to resolve the crisis.
Fuel rods in the core of the No. 1 reactor are fully exposed, with the water level 1 meter (3.3 feet) below the base of the fuel assembly, Junichi Matsumoto, a general manager at the utility known as Tepco, told reporters at a briefing in Tokyo. Melted fuel has dropped to the bottom of the pressure vessel and is still being cooled, Matsumoto said.
Nuclear meltdown at Fukushima plant Telegraph, May 12.
One of the reactors at the crippled Fukushima Daiichi power plant did suffer a nuclear meltdown, Japanese officials admitted for the first time today, describing a pool of molten fuel at the bottom of the reactor's containment vessel.
“Fuel rods in the core of the No. 1 reactor are fully exposed, with the water level 1 meter (3.3 feet) below the base of the fuel assembly, Junichi Matsumoto, a general manager at the utility known as Tepco, told reporters at a briefing in Tokyo. Melted fuel has dropped to the bottom of the pressure vessel and is still being cooled, Matsumoto said.”
In other words, officials have been forced to admit for the first time that reactor 1 suffered a nuclear meltdown, leading to concerns that “radioactive fuel may have burned a hole through the bottom of the containment vessel, causing water to leak.”
http://www3.nhk.or.jp/... (NHK 5/14)
The operator of the Fukushima Daiichi nuclear power plant is trying to locate thousands of tons of radioactive water that has leaked from one of the damaged reactors.
Tokyo Electric Power Company, or TEPCO, says contaminated water is apparently leaking from the No.1 reactor, which is in a state of meltdown.
TEPCO has injected more than 10,000 tons of water into the reactor since the March 11th disaster damaged the plant. But, less than half that amount is believed to remain in the reactor or its container vessel.
The utility says the leaked water is likely in the basement of the reactor building -- still a no-go zone due to concerns over high radiation levels.
In the aftermath of the earthquake in Japan, Twitter is proving "an excellent system" for communicating with chronically-ill patients, say doctors.
In letters written to The Lancet, Japanese doctors say social networking sites have been vital in notifying patients where to get medication.
Although telephone networks were disrupted after the earthquake, internet access remained reliable.
But Japan must now strengthen its primary care system, they said.
Free fish meals a treat for earthquake-hit town Yomiuri 5/15
KESENNUMA, Miyagi--An association of owners of long-distance fishing boats provided 2,000 donburi bowls topped with bonito and tuna to victims of the Great East Japan Earthquake in Kesennuma on Saturday.
People started to gather at 5 a.m. in front of a restaurant where the meals were to be handed out, and the line kept growing until 10:20 a.m. when distribution began.
Kesennuma is one of the nation's largest bases for long-distance fishing, but was devastated by the March 11 tsunami. The association's members wanted to cheer up disaster survivors with the dishes of rice topped with bonito and tuna brought from Yaizu Port in Shizuoka Prefecture.
Association head Hiroaki Katsukura said, "We wanted to express our gratitude to the people of Kesennuma, because they've helped us out in the past. We also wanted to do something to encourage them."
Hamako Koyama, 72, tasted both donburi types and said the free meals were a treat. "I haven't been able to eat much fish since the disaster," he said.
The association plans to hold similar events in Onagawacho in the prefecture and other disaster-hit areas.

Gov't compiling road map for nuke crisis-affected areas (TOKYO, May 14, Kyodo)
The government is compiling a road map to clarify how it will restore areas affected by the nuclear crisis at the Fukushima Daiichi power plant and allow evacuated people to return home, for release as early as Tuesday, government sources said Saturday.
The release may be delayed, however, as the latest findings by the plant operator Tokyo Electric Power Co. indicate a meltdown of the troubled No. 1 reactor's fuel in a development that may affect its aim of bringing the crisis under control within six to nine months.
In solidarity with the people of Fukushima! What do you want? Clean energy! When do you want it? now!
Change always starts with a nice chat around a good dinner! :)
On Sunday 5th of June, we invite you to gather with friends, relatives and neighbours to have a wonderful picnic in a park or even in your street. The 2010 edition was organised in about 70 cities, in more than 20 countries. This year edition is organised in solidarity with the people who were at the center of the huge crisis that happened in Fukushima. While media are slowly going away in quest for fresher news... WE DO NOT FORGET! This pic-nic is a simple action to put it clearly to our governments that we want 100% clean energy as nuclear energy is simply not safe, and human beings do not master this technology. Moreover, to give an example, in Europe only, 143 nuclear power plants provide no more than 20% of the total energy needed! So is it worth taking such a risk for 20% of energy supply? The answer is clearly NO! The answer of many degrowth movements around the globe is, first, to consume less energy and, then, to choose clean energy. This is the message behind this year pic-nic. We hope you'll join us!

This is gonna hurt .... h/t procrastinator john on Thu May 12, 2011 at 06:41:18 PM PDT
Back at the end of March the CEO of TEPCO denied rumors that the company had withheld information:
[Katsumata] faced criticism that the company had supplied a flow of opaque and occasionally wrong information, including a misleading radiation reading, but denied TEPCO withheld details on the Fukushima situation.
"I am very sorry that there have been various mistakes and delays in the timing (of making announcements). But we have never concealed information," he told reporters.
The Asahi Shinbun(Japanese) reports a different story today:
Concerning the accident at the Fukushima Daiichi Nuclear Plant, Tokyo Electric discovered that it did not release data about the high level of radiation in the reactor building of unit 3 that suffered a hydrogen explosion on March 14, even though it had the data on hand on March 13th. TEPCO ascertained this from internal documents. Nuclear power experts indicate that "since this is information needed by workers and the public, they have an obligation to release specific data as soon as possible."This news is seriously going to piss off Kan and Edano, not to mention a lot of the public. The incident is definitely going to be investigated by the government. March 13, by the way, was the last time the company president, Shimizu, made a public appearance until early in April, after he was released from the hospital.
