I wonder if there is a terminology and translation problem with regards to the status of reactor 3. The most recent JAIF report (16:00 March 25) states that "Containment Vessel Integrity" is "not damaged", but for "Reactor Pressure Vessel Integrity", it says "Damage suspected." The prior report (10:00 March 25) says that "Reactor Pressure Vessel Integrity" is "Unknown." www.jaif.or.jp -

Dangerous breach suspected at Japanese nuke plant
news.yahoo.com -
@SteveA [opinion] Very possible, but it's the level of radiation and the type of them which may indicate for mr Nishiyama that it came from the core. As spent fuel rods have been suspected to have been damaged, may be a partial "meltdown", and as it contain Mox, (so plutonium) these radiations could also come from it , with all the water pourred, as far as I understand it.

"Nuclear safety officials in Japan fear the core of a reactor at the Fukushima Daiichi nuclear power plant may have cracked, causing a leak of high levels of radiation." "The government's chief spokesman, Yukio Edano, said 130,000 residents in the area had been encouraged to leave to improve their quality of life, not because their health was at risk." www.guardian.co.uk

@Paul Here's our story on that from earlier this morning: uk.reuters.com -
@Reuters: Mark Kolmar. What does it mean "considering bailing water out of reactors as the radiation is high"? Why would this make anything better? What would they do with the water? Surely any water they replace it with would end up the same? I don't understand what problem they would be trying to fix how? Any expansion/clarification of this statement greatly appreciated.

Excessive radioactivity found in Tokyo vegetable The ministry says the radioactive cesium was detected on Thursday in a leafy vegetable taken from a field in Edogawa ward on Wednesday. The vegetable is called Komatsuna, or Japanese mustard spinach. The radioactive level was 890 becquerels per kilogram, exceeding the legal limit of 500. www3.nhk.or.jp

Earlier in the week, nuclear energy critic and author Hirose Takashi wrote : " Around Fukushima Daiichi Station they measured 400 millisieverts – that’s per hour. With this measurement (Chief Cabinet Secretary) Edano admitted for the first time that there was a danger to health, but he didn’t explain what this means. All of the information media are at fault here I think. They are saying things like we are exposed to radiation all the time in our daily life, we get radiation from outer space. But that’s one millisievert per year. A year has 365 days, a day has 24 hours; multiply 365 by 24, you get 8760. Multiply the 400 millisieverts by that, you get 3,500,000 the normal dose. You call that safe? And what media have reported this?"

@JC Here's some Reuters pieces on radiation levels, uk.reuters.com and uk.reuters.com.

"In a telephone interview with The Japan Times, Shunichi Tanaka, former acting chairman of the commission, said it was irresponsible for the government to force people to evacuate their homes without disclosing concrete data on the calculated exposure risks they face from wind-borne radioactive materials. <...> He said the situation at Fukushima No. 1 is so serious that it is imperative for the government to bring all of Japan's knowledge and wisdom to bear on the crisis because Tepco and the Nuclear and Industrial Safety Agency are outmatched." search.japantimes.co.jp

"Three workers who were exposed to high-level radiation at a crippled nuclear power plant in Fukushima Prefecture arrived Friday at a radiation research center in Chiba city where they are scheduled to undergo specialized evaluation. <...> Electrical engineering firm Kandenko Co., which employs the men, said its workers were not required to wear rubber boots as its safety manuals did not assume a scenario where its employees carry out work standing in water at a nuclear power plant." english.kyodonews.jp

OPINION: Does Japan Need Assistance?
By Rajib Shaw
TOKYO, March 25, Kyodo "Japan needs urgent assistance in different sectors, from volunteer management, to health risk reduction, to prevention of environmental degradation, mass relocation, shelter management, strategic planning and policy direction, to name but some. Japan is known for its reserved nature, dignity and modesty. Japan has been generous to support several countries in different disaster situations, mostly without drawing attention to itself. It is now time to reciprocate that support and to assist Japan in its time of crisis with non-monetary resources." english.kyodonews.jp -
Japan's Prime Minister Kan says the government will strengthen the coordination of efforts to avoid radioactive contamination of air, food and water. He pledges to share information regarding the spread of radiation, and pledges compensation and support to those whose businesses are hurt by the nuclear plant accident.

The latest release of the IRSN (Institute for Radiological Protection and Nuclear Safety), Paris 25 March 8: (in French). "IRSN examines scenarios possible aggravation of the situation, including possible scenarios in case of rupture of the reactor vessel 3. It will be difficult to demonstrate the reality of such a scenario, but the impact in terms radioactive discharges into the environment is being examined. In french: www.irsn.fr Will be in english and japoniase during the day.

"Toshimi Kitazawa told reporters on Friday that the United States urged Japan to quickly switch to fresh water, and offered to help do so. <...> The US forces and Japan's Self-Defense Forces have drawn up plans to anchor off the Fukushima coast US Navy barges capable of carrying large amounts of water, and send water via pipelines to the plant.
The US military is also to provide a high-powered pump to send water through the pipelines, and Japanese SDF vessels are to be mobilized to refill the barges with water." www3.nhk.or.jp -
"More than 240,000 people were still sheltering in some 2,000 evacuation centers as of Friday. <...> According to the National Police Agency, more than 27,500 people were either confirmed dead or remain unaccounted for as of 6 p.m. Friday -- 10,066 deaths and 17,452 missing." english.kyodonews.jp
