Nuclide Analysis Results of Radioactive Materials in Seawater taken near Intake Canal of Fukushima Daiichi Nuclear Power Station (for the data collected on September 22), TEPCO Press Release, September 23,2011:
On September 22, 2011, we conducted sampling of the seawater near the intake canal of Units 1 to 4 of Fukushima Daiichi Nuclear Power Station and analyzed the samples. As a result, some radioactive materials were detected as described in the appendix.
We informed Nuclear and Industrial Safety Agency (NISA) and the government of Fukushima Prefecture of the results above today.
We will continue to conduct same kind of samplings.
Radioactivity Density of Seawater around Bar Screen of Unit No. 1 (inside Silt Fence):
Same measurement for Unit No. 3:
Same measurement for Unit No. 4:
*No measurements were provided for Unit No. 2

And the concern is that…

In my mind I think of this like a camp fire that is dying down. If you stir it up, you get a moment of increased heat and light. A momentary increase that is detectable until the exposed surface cools down again. Unlike a camp fire, these cores are capable of self sustained energy releases. Who knows what the conditions are inside these cores. Each time they are agitated, or the water is inconsistently distributed inside, a change in radiation follows. The concern should be that there are three melt downs of mark 1 boiling water reactors in Japan. That should be followed up by concern over the failure of their design, and then we should be concerned that there are are somethig like 34 of these reactor in use in the USA…

Indeed, and another concern is that they are right next to each other. If they were all 100km away, then the battle would be completely different.

the dry well at reactor #1 was at 411 sv/hr the other day and no word about that?
411 sv/hr!
thats insane!

They do not talk about these values because they claim that the sensor is broken.
Ridiculous. The better explanation is that the vessel is broken and the fuel is under cyclical recriticality.
Report Comment
lol “broken”
yeah you can clearly see how frequently recriticality occurs in the reactor if you just look at the graph on atmc.jp
everytime it drops and then spikes back up def indicates criticality to me…

That was expectable after the heavy rain.

Why do they measure the water at the intake? Wouldn’t it make more sense to measure it at the outlet? It raises a few questions.
Is there any difference in the water at the different intakes? The intakes are quite close to each other and I think they all get their water from the small harbour in front of the plant, so basically it would be the same water more or less.
The radiation they pick up must have leaked into the water first before beeing carried back to the intake.
Didn’t they say that they installed a cooling water recycling system, meaning they wouldn’t have to take in water form the sea anymore?
Perhaps they still need seawater to make ud for the water escaping through the leaks.
Finally they choose to display the readings on graphs with an exponetial scale. That means that the graph appears rather flat, even though the readings vary from around 50 bq/l to about 4,000 bq/l in a about a week (unit 3, 9/15-9/22).
Hard to read useless information presented in a manipulated form to divert your attention from issues they don’t want you to know about, imo.
This seems to be their agenda:
Feed the riffraff (us – the public) some scraps of unimportant information, twist and distort the information so that it is difficult to grasp and hope that the riffraff takes the bait and forget to ask about the really important matters (which we could never dream of answering anyhow).

“they choose to display the readings on graphs with an exponetial scale.”
Thanks Hemisfear, I missed that. Well spotted.

is this spike due to the Typhoon? Large amounts of rain washing debris down to the silt fence?
i suspect the spike is that.

Hey enenewsers, what do you think of the fact that they did not detect iodine? I thought if there was fission going on, you’d have fresh iodine, or not?
Any thoughts on that?

Bread and butter according to tepco they didn’t detect plutonium until july…
Your smarter than that…
You need to understand their position…
Tepco… (we have almost achieved cold shutdown)…
Reality (impossible, liars!)…
Public (How is that even possible)…
If they admitted the detection of iodine than they wouldn’t be anywhere close to cold shutdown…
So the release of the information would only damage their public image.
Infer what the person is doing (its usually the best way to read between the lines). By knowing their main focus (restore the reactors and japan) you can easily identify the corruption involved, by watching the issues they tip toe around…
Everything happens for a reason.
They are omitting the evidence to maintain a level of control, in a situation that is by all means beyond all control…
hope that helped.

in the beginning,
i learned a lot on enenews.
in the middle,
a few of the more scientific related posted links
gave new insights.
in the beginning of the end,
i posted some kidding links, some thought out some just impulse.
for the finish, my opinion is: corium most likely did not happen (because the rods consist of powder which most likely did not melt completely (>2800 Celsius neede)) and the humans there had a bit of luck. It is still a massive mess but no godzilla breeding nightmare.
furthermore it is not worlds end. but hopefully alternative energies will take over soon.

all the other plants are still emmitting all over the globe…theres still work to do!! remember this stuff is accumalitive…no escaping that!

What freaks me is the amount of old plants being recycled from end of life to being used past their prime. Even pro-nuclear people often agree with that, but it is a financial decision of course.
Newer technologies by definition are safer than older ones. All these old plants need to go, it is unrealistic to expect nuclear to go altogether unless everyone goes back to living in a cave.
And yes, I wish they had never existed, but they do.
Back to living near not one, but having around TEN nuclear plants nearby within unpleasantly close popping distance. That’s before anyone starts up with the accusations of being a shill.
Dungeness B (1 dodgy plant close date due 2018), Gravelines (6 reactors, fifth largest in the world), Doel (3 reactor), Borssele (only 1..)

Good morning staycalm, I attended a scientist’s presentation concerning nukes last week in Luxembourg. He told us that from his experierence the old plants’ pressure vessels are becoming brittle from the constant neutron “bombing” during the process.
He said the problem are the welded joints, which get weaker and weaker over time. As it’s not possible to exchange the RPV without dismantling the whole structure, the operators work their way around the problem, for example redirecting the coolant water to avoid temperature shocks for the material.
I don’t think we’d be living in caves without nukes, though.

No cries of ‘shill’ here staycalm, just interested to discuss your point of view
Presume you agree with the notion that the nuclear industry invests considerable resources to further it’s own interests? You might then consider that some technologies with great potential might be suffering from ‘poor cousin’ syndrome, having failed to receive full attention due to the preference for maintaining the status quo.
I submit therefore that we should look closely at all the alternatives, both established and emergent technologies, before deciding which one we stake our future on.

@Staycalm. I wonder what you will say or how you would feel if a nuclear power plant near you explodes and meltdown.

Nuclear is essentially dead in the US, where cost of startup (around $25 billion) is prohibitive as an investment in terms of $/KwH. A new plant simply won’t ever pay for itself in today’s economy. Don’t worry about the new ones, a couple of new ones that might possibly go online in the US will discourage any other risk-happy fools from investing in them, due to nightmarish cost overruns. The real problem we face is getting rid of the 40 year old death traps we now have operating above capacity.
