Japan Earthquake and Tsunami

[dmc]

Also said that Japan recycles spent rods

Do they have to separate paper. plastic and spent rods..?

More info on the one of the materials in vessel

ASTM A 533 B Cl 1 alloy is a low ferritic steel that is less susceptible to embrittlement caused by the nuclear reaction. This fission process releases neutrons which causes this. The question is which is the outer and which is the inner of the vessel. Still digging.

Calling it quits for tongiht. It has been enjoyable. Love digging for this stuff. I will need to call a colleague in the nuke industry to see if he knows.

Id use forged nickel alloy if it were me but im no physicist

Funny, but why forged? ddt would use cold rolled since he is so liberal.

Not good, latest images are showing plumes of white smoke coming from what looks like Unit 4. Radiation levels have jumped to dangerous levels even for workers rotating.

CNN reporting radiation in the tap water up to 50 miles away....

Not good if true. Air samples would be the first to register though.

Why wouldn't it be true?

 

[Puck it]

Why wouldn't it be true?

Need to know who and where the reading taken and with what type of detection device? How high? What type of radiation was measured? There is more to it then just saying the level is high.

Japanese flag was flying on the WGBH video screen over the Pike.

The situation is even more grave when you view it in summary fashion. I fear that the response teams are being overwhelmed with issues.

Fukushima Daiichi crisis

• Reactor 1: Was first to be rocked an explosion on Saturday; fuel rods reportedly 70% damaged
• Reactor 2: There are fears a blast on Tuesday breached a containment system; fuel rods reportedly 33% damaged
• Reactor 3: Explosion on Monday; smoke or steam seen rising on Wednesday; damage to roof and possibly also to a containment system
• Reactor 4: Hit by a major blaze on Tuesday and another fire on Wednesday

Add to that: reactors 5 and 6 are also having "difficulty cooling" :sad:

Even these reactors that were "off line" prior to the quake/tsunami are in danger of failure. When I heard they had pulled all workers from the site last night all I could think of was all 6 of the reactors possibly ending up in meltdown, multipling the chances that at least one of the containment systems would fail.

355: Simon in Oita, Japan writes: "The sensationalist approach of some of the media is starting to grate - stoking fear to sell their product. The British Embassy have provided a very calm and rational analysis of the nuclear threat, along with the Massachusetts Institute of Technology blog and other sources of knowledge (the BBC site has been a lifeline). The engineers at the plant are obviously facing a chain reaction of problems in the most logical manner and deserve our support.

1339: The BBC's Tim Wilcox has met many foreigners waiting to take flights out of Japan at Tokyo's Narita airport. Many, like Aiko - flying home to San Francisco - have resigned from their jobs to leave the country.

1324: Japan has raised the maximum radiation dose allowed for nuclear workers, to 250 millisieverts from 100 millisieverts. It described the move as "unavoidable due to the circumstances", AP reports.

1214: Japanese police have been asked to send watercannon truck to hose down the nuclear plant, Japan's broadcaster NHK is reporting, according to AFP

Good to see Seabrook, NH not in the top 10.

They test the warning sirens fairly often and they can be heard from our home.

#4 was offline too as reports say. Reactor #2 is also running MOX as fuel. There may be others too. MOX is a mixture of uranium and plutonium(left over from surplus weapons grade).

I was thinking about Seabrook. I would say it would be pretty high up on the Tsunami risk list. as there have been faily large events in the fairly recent past:

I did not realize there were six. I thought it was four.

440: Dr Sally Leivesley, a risk management advisor, says huge amounts are being asked of the "very fatigued" workers battling fires at the Fukushima site. "They've been asked by the emperor to give their all, and they will," she tells BBC News.

There are four reactors in the main section of the facility and the other two are adjacent.

Reactors 5-6 are on the far right side of the pic.
