Japan raises spectre of Fukushima 'melt-through'
By North Asia correspondent Mark Willacy
Posted 28 minutes ago
For the first time, Japanese authorities have suggested the situation at the Fukushima nuclear plant may have gone beyond a meltdown.
An official report, which Japan will submit to the UN's nuclear watchdog, says nuclear fuel in three reactors at Fukushima has possibly melted through the pressure vessels and accumulated in outer containment vessels.
Japan's Yomiuri Shimbun newspaper says this "melt-through" is far worse than a core meltdown, and is the worst possibility in a nuclear accident.
This is the first official admission that a "melt-through" may have occurred.
In the report, Japan also admits it was unprepared for the scale of the Fukushima disaster, which struck after a devastating earthquake and tsunami in March.
The report also acknowledges there was insufficient communication between the government and the plant's operator.
Fukushima meltdown – Caldicott says Japan may become uninhabitable – media silent

Dr Helen Caldicott says that the Fukushima nuclear disaster has the potential to make Japan “uninhabitable”, yet the mainstream media in Australia continue to ignore the crisis. Managing editor David Donovan reports.
Yesterday – the same day Germany announced it would close all its nuclear plants because of Fukushima, and dangerous levels of radiation were reported in Japanese clean-up workers – Independent Australia did a straw poll of 50 random people at a metropolitan shopping centre in Queensland. Each of them was asked: “were you aware that there had been a nuclear meltdown at Fukushima in Japan”. Almost all of these respondents recognised the name Fukushima but only 4 of the 50 – a mere 8 per cent – said they had heard of any meltdown.
This rough poll points to deficiencies in popular media reporting in Australia of what some say has the potential to become the most devastating man-made disaster the world has ever known.
That may sound like an alarming claim, so let’s look at the facts...

TRACING JAPAN'S RADIOACTIVE OCEAN
Japan's nuclear agency reported to the IAEA today that the nuclear fuel in three reactors at the Fukushima I Nuclear Power Plant likely melted through the inner containment vessels and not just their cores in the aftermath of the March 11th earthquake and tsunami.
Today's report also more than doubles the estimate of the amount of radioactive materials released—from 370,000 to 770,000 terabecquerels.

Which makes the work of a research cruise just now underway to measure radioactivity in the ocean off Japan even more important.
The 15-day cruise is led by chief scientist Ken Buesseler of the Woods Hole Oceanographic Institution (WHOI) and members of his lab, Café Thorium. They're joined by researchers and technicians from around the world, including from the:
University of Tokyo
University of Hawaii
University of California Santa Cruz
University Barcelona Autonama
State University of New York at Stony Brook
Scripps Institution of Oceanography
Oregon State University
Other labs involved in the investigation:
Tokyo Institute of Technology
Savannah River National Lab
Oxford University
Lamont-Doherty Earth Observatory
International Atomic Energy Agency Marine Environmental Studies Lab, Monaco
IAEA/University of Bremen
Comenius University Bratislava Slovakia

'Melt-through' at Fukushima? / Govt report to IAEA suggests situation worse than meltdown
The Yomiuri Shimbun
Nuclear fuel in three reactors at the Fukushima No. 1 nuclear plant has possibly melted through pressure vessels and accumulated at the bottom of outer containment vessels, according to a government report obtained Tuesday by The Yomiuri Shimbun.
A "melt-through"--when melted nuclear fuel leaks from the bottom of damaged reactor pressure vessels into containment vessels--is far worse than a core meltdown and is the worst possibility in a nuclear accident.
The possibility of the situation at the plant's Nos. 1 to 3 reactors was raised in a report that is to be submitted to the International Atomic Energy Agency.
If the report is released as is, it would be the first official recognition that a melt-through has occurred.

We have planted a garden (18 miles north of Seattle), not sure if we will be able to eat any of it. But none of these concerns weigh half so much on my mind as to whether or not Weiner should resign and become a regular on the O'Reilly factor.
....it's not even worth blaming anyone anymore...we are all totally fucked...

I know how you feel because I feel the same way.
But fuck it. We're all gonna die anyway. Go enjoy life while you can. Eat spinach, drink milk, sit in the sunshine, swim in the waters, play with your kid in the grass.
That's the attitude I'm taking.
Hell, I thought maybe Chile would be a good place to go to, if I had the money, and now it's blowing up with that freaking volcano.
No place is safe. We could all die tomorrow.
Enjoy what you can while you can. Don't live in fear.

Nobody knows exactly what happened to the spacecraft's deadly cargo. While governments prefer to think it is lying at the bottom of the Pacific Ocean, there is growing evidence--including thousands of eyewitness reports like the VanderBrinks'--that the plutonium fell intact into the Andes. It is almost certainly still lying there, probably somewhere near the border between Chile and Bolivia. And nobody seems to care who finds it.
