April 10 retrospektiv link-dump

Links I posted on Facebook retroactivly reposted to Blogger with some messy html remaining.
:-(This is May 5 but this post's links were collected prior to Apr 10)-:
This way I won't have to look at facebook for my links either, because I hate (and like) facebook.
My apologies to my reader for the complete lack of posts in the post-earthquake post-tsunami recent past.

Normally, the public is supposed to only get ONE extra millisievert per year from nuclear-industrial actions, nuclear workers 50 millisieverts.

The Japanese govt is saying 20 millisieverts a year is now OK for the public before they would consider evacuation
(and note that some UNevacuated areas are getting much more than that weekly),
250milliSvrt for nuclear workers (That is actually in line with guidelines for life-saving activities.)
This is a commercial site, but has a good explanation.

Atoms are not all stable. The excess energy contained in an unstable atom is released in one of a few basic particles and energetic waves. The Greek alphabet is used to name the particles (in the order of their discovery).

Another speedy solution suggested by some experts is to pour concrete or sand over the overheated reactors, not waiting until they cool. The tactic has been dismissed by Japan's nuclear safety agency and other experts have called it risky as the nuclear fuel may melt through the container.

Information is beautiful. Radiation, not so much.

I would have said "castle made of sand" (Hendrix tribute)
A society that depends on nuclear energy is just like a house of cards

A little long but a sign of change, read later?
Japanese Opposition MP, Taro Kono, has long argued against Japan's reliance on nuclear power, and he says Japan must move to an energy strategy that includes renewables and natural gas. Taro Kono is also on the Liberal Democratic Party's counter-relief committee. The group is examining better ways of responding and preparing for such disasters as this month's earthquake and tsunami.

Hell no, we won't go, hell no, we won't glow.
Companies dispatching workers to Tokyo Electric Power Co.'s crippled Fukushima Daiichi nuclear power plant are refusing to adopt the government-imposed provisional limit on radiation exposure for those workers at the plant, saying it would not be accepted by those at the site, Kyodo News learned Saturday.

Former U.S. Nuclear Regulatory Commission member Victor Gilinsky said the Japanese crisis seems far tougher than the Hanford Nuclear Reservation in Washington State, regarded as the most highly contaminated nuclear weapons site in the United States. At Hanford, the Energy Department reportedly plans to decommission eight reactors and process about 58 million gallons of radioactive sludge now in leaky underground tanks at a cost estimated up to $130 billion.

Possible reason why tapwater cesium and iodine is undetectable now: added filtering.
Efforts to protect Tokyo's tap water from radiation leaked by the damaged Fukushima No. 1 nuclear plant have led to a run on Indonesian coconut husks.

NPR gets critical.
Experts say that in the weeks following the series of explosions and fires inside the reactors at the Fukushima Dai-ichi power plant, TEPCO made very costly — and avoidable — mistakes. The company, they say, was deeply surprised and overwhelmed by the course of events.

NPR on liquefaction
The violent shaking from Japan's March 11 earthquake stirred up the soil, leading to broken water pipes, tilted utility poles and manholes that popped out of the ground. The phenomenon, known as liquefaction, was particularly noticeable in areas built on land reclaimed from the sea.


OK... He probably went a little foo far with the word "explosion" and that idea, but I don't think he was part of the "alarmist" media. I had to work this out and reach my own state of alarm all by myself, only found this much later.

dcbureau.orgThe threat of a fission explosion at the Fukushima power facility emerged today when the roof of the number three reactor exploded and fears that a spent fuel pool, located over the reactor, has been compromised.

Slides 4, 5, 9, 10, and 11 are especially relevant to understanding the fuel amounts (or =the tonnage of radwaste) at Fukushima Daiichi, and how they have re-stacked fuel assemblies beyond the design parameters in the cooling pools.

The plaque that you can see in this panorama with the date 35.5.24 indicates the water level of the tsunami caused by the 1960 (Showa35) May 22 Valdivia, Chile earthquake, a magnitude 9.5 and the largest in recorded history.

MITO, Ibaraki Pref. (Kyodo) The mayor of Tokai, Ibaraki Prefecture, has criticized the central government and Tokyo Electric Power Co. over their handling of the nuclear crisis in neighboring Fukushima Prefecture.
TOKYO – Something fascinating is afoot in Japan: anger. People are fuming about the nuclear crisis that put their nation in the spotlight for all the wrong reasons.

“We have been sacrificed so that Tokyo can enjoy bright lights,” said Takao Takahashi, 68, a tobacco farmer.

‎"Nuclear reactors are inherently dangerous, and will always be vulnerable to the potentially deadly combination of human error, design failure and natural disaster. Governments around the world must commit to a future based on energy efficiency and renewable energy – nuclear power has no place in a modern safe and secure energy system!"

We must deliberate this matter slowly and carefully...
zzzzz The government is reviewing the radiation exposure level currently used to designate the evacuation zone around the Fukushima Daiichi nuclear plant, as the nuclear crisis triggered by last month's massive earthquake and tsunami continues to unfold, its top spokesman said Wednesday.

Radioactive Cesium in Chiba water peaked around 3-23 or another spike on 3-27 but has been largely undetectable since. Radioactive iodine is well below the 200 bq cutoff for infants. I think i'l go back to tapwater and save the bottled water.

[Chiba has a lot less Iodine-131 and a little less Cesium-137 than Tokyo.]
