#Fukushima I Nuke Plant Reactor 3: Radiation Went UP After Packbots Cleaned the Guide Rail to CV

After 2 Packbots wiped the guide rail to the Containment Vessel hatch on the 1st floor of Reactor 3, they were sent back in to measure the result of their operation in terms of radiation levels.

Well, the levels may have gone up. As you can see in the handout for the press on November 22, 2011, after the cleaning operation the measurement by the survey meter fluctuated so much that TEPCO couldn't put down the single number for each location.

What had been 800 millisieverts/hour on November 14 was anywhere between 570 to 1,600 millisieverts/hour on November 19.

From TEPCO's handout for the press on November 22, 2011:

If the radiation level is not static then I suppose it's the reactor breathing out thru the leaking equipment hatch.

Imagine you are a cleanup worker and suddenly you notice a warm (or rather, hot in the truest sense) wind blowing from the reactor and your dosimeter going off-scale. Not nice, but remember, this is "Nuclear Boy". Just as in the animated cartoon.

Maybe they should also measure the air temperature or use a smoke generator to find the exact placement and size of the leak in the hatch door insulation.

Fukushima is interminable. The fuel will have to be continually cooled with water. And no one knows where the fuel is.

And this fuel that no one can locate has to be removed from the plant. But it's obvious that the plant is too contaminated for any human operations. Removing the fuel is looking like an impossibility. Robots won't cut it.

Meanwhile, the water is recycled and radioactive extracts pile up. Extremely radioactive sludge. Which is incinerated in Tokyo and trash plants up an down Japan.

Just yesterday we learned that massive deposits of radioactive particles have settled like marine snow across 8 pc of Japan's land mass. The acute leukemia of the television presenter who gorged on Fukushima's food as a propaganda stunt is potentially indicative of mass radiation danger.

The crisis will not end, but it can be kept to a low simmer as the becquerels denature reality.

reality is a nightmare. We need a very capable robot army. Is there any word on such a plan? This exercise of cleaning rails reminds me of the helicopters dropping water on the freshly wasted reactors. These folks need to share with the world what the action plan is. When I say folks I am talking more about the Japanese government rather than tepco. There are plenty of people outside of Japan who are very anxious about all of this. If the Japanese government does not act I cannot see some world power resisting the urge take some drastic action to help protect the rest of humanity whether the government of Japan likes it or not.

Fukushima is releasing the radiation equivalent of 27 Hiroshimas per day. The mass media finds that this is NOT news worthy. Could it be that GE, who makes nuclear power plants, and owns most mass media outlets, does now ALLOW reporters on who could affect sales or profits of new nuke plants?

Those rails look to have about the amount of corrosion expected? Looks quite advanced. Are they stainless?

And the sludge looks extremely toxic. What a freaking mess.

As Atomfritz said, the reactor is probably breathing, and the corrosion/sludge certainly point you in that direction.

Note that TEPCO only feels permitted to release these tiny snippets of acknowledgement.
Scenario is converging to a Chernobyl elephant's foot-type of picture.

All three reactors are still generating substantial residual heat, together around 10 megawatts worth, which is boiling off some of the cooling water being injected. That steam carries with it a burden of radioactive decay products, so any place it flows over or condenses would be contaminated. How TEPCO is managing to prevent the inside of the cover over reactor 1 from becoming lethally contaminated is an interesting question.

@anon at 7:07AM, thanks for the link.

I don't know where she came up with "27 Hiroshimas a day". It is decidedly not from the press conference she is referring to. And Reactor 3 being not far off the water table?

Stating that Fukushima is releasing "27 Hiroshimas per day©" is utterly ridiculous and counter-productive in terms of understanding the dangers. 27 Hiroshimas per day now brings this accident to something like 6,500 Hiroshimas. Over six thousand Hiroshimas, and not a single death identifiable as caused by radiation. It makes people distrust all news, and obfuscates the differences between nuclear explosions and decay heat from fissioned products. Not to mention its probably a much sillier comparison than the oft-sneered at banana (potassium-40) comparison.

netudiant said...

Just as an aside, the speculation about phreatic steam explosions once the corium hits the water table seems silly.
Ground water is seeping into the reactor basements along with the injected water. The reactors are being continuously flooded with water and the fuel is boiling some of it. So the fuel has already hit whatever water table there is. Radioactive steam is bad enough, no need to pile on fictional explosions, which would require either steam confinement or massive increases in the reactivity of the fuel.

Atomfritz said...

The point anon 1:23 speaks of is completely valid.

Low radiation consequences are seldomly that spectacular and uniquely identifiable like instant leukemia, people's heads exploding and such.

It is very fortunate to the nuclear cartel that the effects can be shown with certainty only through statistical observations.
By keeping the statistical data unpublished or even classifying them, the proof can be hidden from the public.

Ernest Sternglass demonstrated this in his classic book "Secret Fallout" (download the book here: http://nucleardemolition.com/SF.pdf ).

Low radiation, as mass-dispersed over big parts of Japan, hits the young ones hardest, unborn to children.

Expect reports about such findings to be very rare, as they will be shown to a very limited audience only and get suppressed by the mass media.

One example of such news leaked to the public:

"Smaller increase in children's weight in Fukushima"

A survey shows that some children in Fukushima Prefecture have smaller average weight gains this year compared to the year before. A pediatrician says the results indicate the negative effects of the nuclear plant accident in March.

Doctor Shintaro Kikuchi tracked the weights of 245 children aged from 4 to 6 in 2 kindergartens in Koriyama City, Fukushima Prefecture. The results show an average weight increase of 0.81 kilograms over the past year through June. The increase for children in the same age group the previous year was 3.1 kilograms."

(found here: http://ex-skf.blogspot.com/2011/11/radiation-in-japan-spiders-in-iitate.html?showComment=1320767053539#c3338831731177856771 )

So I think the relevant proof data for the radiation damage to the japanese people will be buried in the statistical offices' files.
As Sternglass showed, in the USA such data are kept away from the public and even most scientists as if they were pure plutonium.
I doubt that in Japan there will be more glasnost.

@ netudiant
I think the fact that Tepco apparently doesn't make any attempt to cover #3 and #4 like #1 could be an indication that things aren't going well.

We know the containment is busted, and the reactor has melted out.

If chunks of corium are dropping and splashing we probably see waves of radiation.

That or it's tied to local winds stirring up hot particles.

It would have been quite natural for the radiation to "go up". After each dusting operation at home you can also see dust levels in the air that were lower before dusting. Yet still, the TOTAL amount of dust would've gone down, by 1, 10, 100 or 1000% - depending on the overall amount of deposit that you removed. So the cleaning operation may still have "defused" much more radiation that could have or could not have, as the case may be, been distributed throughout the environment at a later date. Airborne radiation measurements therefore are not necessarily a good guide to condemn the operation although TepCo has shown an incredible amount of shoddiness and stupidity in dealing with the situation. And no, I am not a pro-nuclear "fan" - but we should try to put everything into perspective, it's bad enough as it is.

anon@4:21 Sorry to burst your conspiratorial bubble, but the original story of the underweight kids was reported by NHK, the king of mass media here in Japan. And of course when you evacuate your home and are living in a high school gymnasium with 300 of your closest friends, it might not be so surprising that you should put on weight at a lower rate than your peers living elsewhere.

And in all fairness, 2:16, since you mentioned arenas of activity, Atomfritz' Sternglass link is instructive.

You see, when you pollute the environment with multiple sources of radiation you get effects like this,
"And indeed, when Dr. Stewart and David Hewitt examined the available records for the number of X-ray films taken, they found that there were distinctly fewer cancer cases among the children whose mothers had only one X-ray [when pregnant] than among those who had four or more. " p.18

I'll insert a lol here, as the R2 Finn's intended effect is entirely analogous to this effect,
"For example, whenever the X-rays had been taken only of other parts of the body, such as the arms and legs, so that only a small quantity of scattered radiation reached the unborn child in the womb, the increase in cancer risk was only about one-fifth as great as in those cases where the abdominal region itself was X-rayed. "

Even one-fifth increase is notable.

At what point did Fukushima exceed Sternglass' "threshold"?
There's your conspiracy.
