IAEA Briefing on Fukushima Nuclear Emergency (18 March 2011, 14:00 UTC)
On 18 March 2011, Graham Andrew, Special Adviser to the IAEA Director General on Scientific and Technical Affairs, briefed both Member States and the media on the current status of nuclear safety in Japan. His opening remarks, which he delivered at 14:00 UTC at the IAEA headquarters in Vienna ...
Press Release (Mar 18,2011)
Assessment of INES (International Nuclear and Radiological Event Scale) on the incident at Fukushima Daiichi and Fukushima Daini Nuclear Power Station
March 18, 2011
Tokyo Electric Power Company
Masataka Shimizu, President
It has been announced that the assessment of INES (International Nuclear
and Radiological Event Scale) on the incident at Unit 1, 2, and 3 of
Fukushima Daiichi Nuclear Power Station caused by Tohoku-Taiheiyou-Oki
Earthquake resulted in "Level 5". We are taking this assessment very
seriously.
We sincerely apologize to all the people living in the surrounding area of
the power station and people in Fukushima Prefecture, as well as to the
people of society for causing such great concern and nuisance.
We are taking this reality as an extreme regret, although it was caused by
the marvels of nature such as tsunami due to large scale earthquake that
we have never experienced before.
While receiving support and cooperation from the Japanese government and
related department and local authority, we will continue our maximum effort
to converge current situation
Unit Status
1 • Reactor cold shutdown, stable water level, offsite power is available.
• No refrigerant is leaked in the reactor contaminant vessel.
• Maintain average water temperature at 100°C in the pressure restraint.
2 • Reactor cold shutdown, stable water level, offsite power is available.
• No refrigerant is leaked in the reactor contaminant vessel.
• Maintain average water temperature at 100°C in the pressure restraint.
3 • Reactor cold shutdown, stable water level, offsite power is available.
• No refrigerant is leaked in the reactor contaminant vessel.
• Maintain average water temperature at 100°C in the pressure restraint.
4 • Reactor cold shutdown, stable water level, offsite power is available.
• No refrigerant is leaked in the reactor contaminant vessel.
• Maintain average water temperature at 100°C in the pressure restraint.
• In the Unit 1, 2, 3 and 4, which automatically shut down due to the
Tohoku-Chihou-Taiheiyo-Oki Earthquake on March 11th, 2011, we had
been preparing measures for decreasing the pressure of each reactor
containment vessel since March 12th. However, on March 17th, we
released such preparation in all of the Units.

What is "Corium"?
Maybe we should have used stone blocks, even though they may melt as well; eg: Pyramids...
The plume of radioactive material from the Chernobyl reactor accident passed over the United Kingdom and will increase the radiation dose to the population in the coming year. The increase above the normal annual dose from natural radiation, averaged over persons of all ages, will be about 15% in the north and 1% in the south of the country. Averaged over all ages and areas, the increase will be about 4%. This excess dose will decrease substantially in subsequent years.
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.
British farms still contaminated
Several days after the accident, a vast radioactive cloud drifted across parts of the UK, leaving a blanket of poisonous caesium-137 over England, Wales and the south and west of Scotland. In 1986 and 1987, restrictions were imposed on approximately 10,000 farms, of which 2,144 were in Scotland alone. Restrictions in June 1986 covered 5,100 farms in North Wales, about 120 in Northern Ireland and 1,670 in Cumbria in England.
More than a third of Britain is still contaminated by radioactivity from the Chernobyl disaster two decades ago, and children are getting cancer as a result, an Independent on Sunday investigation has established.
Official measurements - published in a report launched in London yesterday - show that at least 34 per cent of the country will remain radioactive for centuries as the result of the accident, which took place 20 years ago on Wednesday.
And scientists have found rates of thyroid cancer in children in Cumbria, the worst-affected part of England, rose 12-fold after the catastrophe - and blame fallout from the radioactive cloud that spread from the stricken reactor. This confounds government assurances at the time that the radiation in Britain was "nowhere near the levels at which there is any hazard to health".
United Nations nuclear and health watchdogs have ignored evidence of deaths, cancers, mutations and other conditions after the Chernobyl accident, leading scientists and doctors have claimed in the run-up to the nuclear disaster's 20th anniversary next month.
In a series of reports about to be published, they will suggest that at least 30,000 people are expected to die of cancers linked directly to severe radiation exposure in 1986 and up to 500,000 people may have already died as a result of the world's worst environmental catastrophe.
Pentagon officials reported Sunday that helicopters flying 60 miles from the Fukushima Daiichi nuclear plant picked up small amounts of radioactive particulates — still being analyzed, but presumed to include cesium-137 and iodine-121 — suggesting widening environmental contamination.
Garwin's criticism centers on what he sees as a glaring omission--the report's failure to cite the findings of a 1993 study produced by the U.N. Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), which estimated that the worldwide 'collective effective dose' from the Chernobyl accident was about 600,000 man-sieverts. He also refers to a report published last summer by the National Academy of Sciences on the effects of ionizing radiation, which concludes that each dose of whole-body radiation causes a lethal cancer at the rate of 0.04 cancer deaths per sievert of exposure.
