@dean- hello!

An important report that eliminates the theory that different concentrations of hydrogen might have caused the different explosive magnitudes between Units 1 and 3 : www3.nhk.or.jp "The agency says about 1,000 kilograms of hydrogen was produced at the No. 1 reactor when the fuel rods began to be exposed 2 hours after the quake and the metallic fuel containers oxidized one hour later. The same phenomenon took place at the No. 3 reactor some 43 hours after the quake, resulting in the production of 1,000 kilograms of hydrogen."

@elainekirk "But MOX is also temperamental. Physicist Arjun Makhijani, president of the Institute for Energy and Environmental Research in Takma Park, MD., spoke to TIME earlier in the week and heaped scorn on the Mark 1 reactors used at the Daiichi site. His criticism in that conversation was the comparatively flimsy (by nuclear reactor standards at least) containment vessels used in the Mark 1s. But he's no fan of the use of MOX either."

"What Makhijani means by "accidental criticality," of course, is that the stuff [MOX] just combusts more easily. That's particularly dangerous in a Mark 1, according to some studies. A report by the Sandia National Laboratories in Albuquerque, for example, found that in the event of a core meltdown, a Mark 1's containment vessel has a 42% chance of failing—a whole lot closer to a coin flip than you want with something like a nuclear reactor" That, more than anything, explains why the day began with flyovers by water helicopters. And that explains why we're likely to see a lot more of the same—at least until another Daiichi reactor starts to look even deadlier. ecocentric.blogs.time.com

Report in Japanese that seems to say the Unit 3 blast was a detonation www.tokyo-np.co.jp Can anyone who can read Japanese explain it's main point? A lot of people don't know that hydrogen explosions can be either deflagrations or detonations. The google translation is not so good : translate.google.com

GSDF colonel recounts fearing for life in Fukushima reactor blast
A Ground Self-Defense Force officer who was nearly killed by one of the hydrogen explosions at the stricken Fukushima No. 1 power plant in March recalled Sunday how the blast made him fear for his life and those of his men.

"I thought that if it was a bad blast, we would not survive it," said Col. Shinji Iwakuma, leader of the GSDF's Central Nuclear Biological Chemical Weapon Defense Unit.

The March 14 blast at the No. 3 reactor injured four of Iwakuma's men just as the six-member team was preparing to spray water onto the crippled reactor, which lost its cooling system in the March 11 quake and tsunami and was overheating to dangerous levels.

While the team is experienced in dealing with nuclear, biological and chemical weapons, Iwakuma, 49, said that a mission requiring the cooling of an out of control reactor was an "unforeseen" scenario.
Iwakuma, who headed out to the No. 3 reactor with five men in three vehicles, was about to open the door of his car when the hydrogen explosion occurred at 11:01 a.m.
The thundering explosion and accompanying blast wave sent concrete and radioactive debris soaring about 70 meters into the air, obscuring his view in a cloud of gray dust, the colonel said.
"I think the debris fell for several dozen seconds, but it felt like it was for a very long time," Iwakuma said.
After managing to get out of his car, he noticed that his men were injured, dragging their legs or holding their arms tightly.
"Are you all right? We will get out of here right now," Iwakuma told them. One man had to be carried over his shoulder.
The dosimeter they had with them was giving off readings of about 20 millisieverts at the time.
Iwakuma said Tokyo Electric Power Co. did not warn them there was a danger of a hydrogen explosion occurring and only said unit 3 was unstable.
"Tokyo Electric was desperate to stabilize (the plant), so I am not angry at them," Iwakuma said, but added, "If there is a possibility of an explosion, I would be reluctant to send my men there."

@lillymunster : ha, you just made my children LOL ....

@elainekirk @lillymunster : is 10 year old fuel still "fresh" ?

hello to all

oops..

elaine/lilly/Edano... any areas you want me to focus on now?

@bobby1= you still there?

@Meretisa yes
