Japan Nuclear Crisis Part II

When they say the highest recorded radiation so far they must mean in a certain location. Where is it? The control room? The site boundary? There was already 400 mSV/hr. recorded near reactor 3 a few days ago and 89 mSV/hr. recorded from the helicopter dropping water.

20msv equal 2 rem per HOUR, here are DOE limits

It was "near where workers were trying to reestablish electrical power" -- wherever the heck that is.

Great to see worst case "scare tactic" scenarios not being realized, tough situation, but becoming obvious it will not be a global and probably not even regional disaster. Meanwhile the pain and suffering continues from the real tragedy, the tsunami and earthquake, God bless the people of Japan.

Hadn't seen this posted...oops....

  • 2220: Japan turned down an earlier US offer to provide technical support for cooling fuel rods at nuclear reactors hit by a massive earthquake and tsunami, a Japanese newspaper said on Friday, reports AFP.

  • 2226: The Yomiuri Shimbun newspaper, quoting a senior official of the ruling Democratic Party of Japan, said the US made the offer immediately after the disaster damaged Fukushima No 1 nuclear plant. According to the unnamed senior official, US support was based on dismantling the troubled reactors run by Tokyo Electric Power (TEPCO) some 250 km (155 miles) northeast of Tokyo. However, the government and TEPCO thought the cooling system could be restored by themselves, the report said.

So the Obama Admin's first response was a conditional offer (bordering on extortion?) that they'd only help if Japan agreed to shut down a nuclear plant (pre-explosions) that the country might need for recovery? Politics and anti-nuke ideology ahead of charity to one of our key allies? Not enough info from that one base article and quotes to assume this interpretation, nor if it was Japan that erred in not agreeing to such an offer. So far it appears that in the early hours of the nuke plant crisis it was not a foregone conclusion that efforts to restart the cooling process would fail.

Recall the timeline: earthquake on Friday, by Saturday morning Sec of State Hillary Clinton said the US was flying coolant in to Japan, but in the afternoon the story oddly changed to nothing was flown in, with some political websites mocking Clinton for a supposed misstep. Could explain why in the last few days leaks have come out that she is furious with the admin (though Libya is a part of that) and her terse interview where she said she wouldn't return for another term in the admin.

So 20 workers have possibly been treated for radiation sickness but the "legal" limited was raised to 250 mSV/year. A disconnect? From what I've read, radiation sicknesses does not typically appear until higher levels than 250 mSV.

For further context, 1 Sv = 1000 mSv (millisieverts). Death can occur at 30 Sv or 30,000 mSV.

The highest radiation we have seen is 400 mSV/hour. This was at reactor #3.

Odd. Wikipedia had different levels.

I am so tired of people espousing their political opinions and lobbing guilt trips in this thread. It's completely ridiculous, try to control yourself. No one cares what you think.

Odd, since you didn't express any indignation to post #780, which suggested some Japanese should commit suicide out of shame for turning down this 'offer':

I knew about the first, but not the second ( the reason for declining the offer.)

That's not a "oops." That decision has become a shame (and loss of honor) inducing decision which could lead to suicide.

The cultural heritage of suicide as a noble tradition still has some resonance. While being investigated for an expenses scandal, Cabinet minister Toshikatsu Matsuoka took his life in 2007. The governor of Tokyo, Shintaro Ishihara, described him as a "true samurai" for preserving his honour.

I'm just pointing out that such blame immediately thrown at the Japanese for turning down the 'offer' may be misdirected.

1) I was watching basketball, didn't see it, obviously that's ridiculous

2) I agree. In hindsight it was obviously a horrible mistake, but I can see where they could never have imagined this happening. I mean, at the Daini plant, they had a cooling failure in 3 of the reactors and were able to restore the cooling to all 3 before anything serious happened and they are all in cold shutdown now. There's no guarantee our plan would have worked any better than this one has.

Well the good news is that it looks like they're getting water into the reactor vessels (1, 2 and 3) at least. I didn't realize they were able to accomplish that. That's according to that report posted above, unless I misunderstand.

The - is below the top of the rods I believe? Previous report had -1400 on reactor 2. The latest report had -1800.

Ahhh... I see. So they're injecting water from a fire hose but not able to increase the water level? I wonder how that could be? Could it be boiling off that quickly? Maybe a leak somewhere?
