Radiation Levels Skyrocket at Fukushima
Painting by Jonathan RaddatzRecord high levels of radioactive tritium have been observed in the harbor at Fukushima.
Japan Times notes:
The density of radioactive tritium in samples of seawater from near the Fukushima No. 1 nuclear plant doubled over 10 days to hit a record 1,100 becquerels per liter, possibly indicating contaminated groundwater is seeping into the Pacific, Tokyo Electric Power Co. said.
***
Tepco said late Monday it was still analyzing the water for strontium-90, which would pose a greater danger than tritium to human health if absorbed via the food chain. The level of cesium did not show any significant change between the two sample dates, according to the embattled utility.
On June 19, Tepco revealed that a groundwater sample taken from a nearby monitoring well was contaminated with both tritium and strontium-90.
***
During a news conference Monday in Tokyo, Masayuki Ono, a Tepco executive and spokesman, this time did not deny the possibility of leakage into the sea, while he said Tepco is still trying to determine the cause of the spike.
Kyoto reports:
A sample collected Friday contained around 1,100 becquerels of tritium per liter, the highest level detected in seawater since the nuclear crisis at the plant started in March 2011, the utility said Monday.
***
The latest announcement was made after Tepco detected high levels of radioactive tritium and strontium in groundwater from an observation well at the plant.
Indeed, the amount of radioactive strontium has skyrocketed over the last couple of months at Fukushima.
The New York Times writes:
Tokyo Electric Power, the operator of the stricken nuclear power plant at Fukushima, said Wednesday that it had detected high levels of radioactive strontium in groundwater at the plant, raising concerns that its storage tanks are leaking contaminated water, possibly into the ocean.
***
The company has struggled to store growing amounts of contaminated runoff at the plant, but had previously denied that the site’s groundwater was highly toxic….
Xinhua reports:
Very high radioactivity levels were detected in groundwater from an observation well at the crippled Fukushima Daiichi nuclear plant, said the plant operator Tokyo Electric Power Co. (TEPCO) Wednesday.
***
The observation well was set up on the Pacific side of the plant’s No. 2 reactor turbine building last December to find out the reasons why radioactivity levels in seawater near the plant remained high. The company said the sampled water could be from the contaminated water that seeped into the ground.
Reuters points out:
Testing of groundwater showed the reading for strontium-90 increased from 8.6 becquerels to 1,000 becquerels per litre between Dec. 8, 2012 and May 24.
BBC notes:
High levels of a toxic radioactive isotope have been found in groundwater at Japan’s Fukushima nuclear plant, its operator says.
***
Strontium-90 is formed as a by-product of nuclear fission. Tests showed that levels of strontium in groundwater at the Fukushima plant had increased 100-fold since the end of last year, Toshihiko Fukuda, a Tepco official, told media.
Other types of radioactive materials will continue to pose a hazard for decades. As nuclear engineer Arnie Gundersen explains:
The radiation exposures are going up. What you’re seeing is a lot of this stuff is getting revolitalized. It’s in the first couple of inches of dust, and when the wind blows it moves into areas that have been previously cleaned.
***
This will go on for decades, as the cesium goes down in to the soil, the roots bring it back up and into the plant structures and the leaves fall on the ground and the cycle continues.
(Some portion of this radiation will hit the West Coast of North America … which may end up with even higher radioactive cesium levels than Japan.)
The bigger picture is that the Fukushima reactors are wholly uncontained … and radiation will continue to spew for decades … or centuries.
Japan Times reports:
A U.N. nuclear watchdog team said Japan may need longer than the projected 40 years to decommission the Fukushima power plant and urged Tepco to improve stability at the facility.
The head of the International Atomic Energy Agency team, Juan Carlos Lentijo, said Monday that damage at the nuclear plant is so complex that it is impossible to predict how long the cleanup may last.
“As for the duration of the decommissioning project, this is something that you can define in your plans. But in my view, it will be nearly impossible to ensure the time for decommissioning such a complex facility in less than 30 to 40 years as it is currently established in the road map,” Lentijo said.
The government and Tokyo Electric Power Co. have predicted the cleanup would take up to 40 years. They still have to develop technology and equipment that can operate under fatally high radiation levels to locate and remove melted fuel. The reactors must be kept cool and the plant must stay safe and stable, and those efforts to ensure safety could slow the process down.
The plant still runs on makeshift equipment and frequently suffers glitches.
***
The problems have raised concerns about whether the plant … can stay intact throughout a decommissioning process. The problems have prompted officials to compile risk-reduction measures and review decommissioning plans.
***
“It is expectable in such a complex site, additional incidents will occur as it happened in the nuclear plants under normal operations,” Lentijo said.
***
The IAEA team urged the utility to “improve the reliability of essential systems to assess the structural integrity of site facilities, and to enhance protection against external hazards” and promptly replace temporary equipment with a reliable, permanent system.
Indeed, the locations and condition of melted Fukushima fuel is still totally unknown. Shimbun reports:
The workers have yet to gain a grasp of the locations and condition of the fuel debris. They have yet to develop extraction equipment and determine removal methods.
Mainichi notes:
Uncertainty over the location of melted fuel inside the crisis-hit Fukushima No. 1 Nuclear Power Plant continues to cast a shadow over plans to remove the fuel at an early date…. Reactor Nos. 1-3 at the plant contained a total of 1,496 rods of nuclear fuel in their cores…. Each fuel rod weighs about 300 kilograms, and a high level of technical expertise would be required when undertaking a remote control operation to cut up and retrieve clumps of scattered radioactive materials weighing a combined 450 tons or thereabouts…. the cores of reactors at the Fukushima plant have holes, and the task at hand is finding which parts have been damaged.
Indeed, the technology doesn’t yet exist to contain – let alone clean up – Fukushima.
Mainichi notes:
In a news conference on June 10, a representative of the Ministry of Economy, Trade and Industry’s Agency for Natural Resources and Energy said that bringing forward the plans would be dependent on developing technology, and suggested that the plans might even end up being delayed.
Scientists are considering freezing the ground around the Fukushima reactors. Australian Broadcasting Corporation reports:
The Japanese government has ordered the operator of the Fukushima nuclear plant to freeze the soil around its crippled reactor buildings to stop groundwater seeping in and becoming contaminated…. According to a report compiled by a government panel on Thursday, there are no previous examples of using walls created from frozen soil to isolate groundwater being used for longer than a few years. This means the project at the Fukushima plant poses “an unprecedented challenge in the world”.
Japan Times reports:
The panel’s draft report said the government and Tepco hope to create the frozen-soil walls between April and September 2015…. A rough estimate suggests that groundwater seepage into the basements would be reduced from 400 tons [every day] to 100 tons once the frozen-soil walls are built.
Another high-tech solution being proposed: injecting cement into the Fukushima reactors.
And then there are the spent fuel pools, which continue to be one of the main threats to Japan, the United States … and all of humanity.

Teachers do work hard but have to teach to tests. A plank since the 1980's was to destroy public education. Kids love to learn, they just need to be taught content that is interesting and compelling. Teachers who are slaves to test scores become depressed and lose the passion they once had to educate the youth. I know many teachers and they are HORRIFIED by what the last 30+ years have wrought. It's a travesty, the waste of one of the greatest resources on earth our youth.
Too true. Teaching to the test is what No Child Left Behind really was. Mind numbing, rote teaching. Loss of recesses due to too much required curriculum and constant change of focus (politically inspired).
Kids are sponges. You should present them with diversity and plenty of options. Testing shouldn't really occur until the 4th grade or so.
NCLB got direct access to ur child's info for military recruitment unless you opted out before their freshman year from both the school admin & JAMRS.
Even with that there is a loophole that if ur child's name, address, TN, were published in the school directory they could still target them for recruitment.
F-GWB
BTW, I opted my kid out & he was still a target.
nuclear sponges....
I choose booze
+1 to this comment and +100 for GW's coverage of this disaster.
Besides those up arrows, not much positive about the situation. People think I'm messing up my swear words when I try to talk Fukushima with them in normal conversation.
Lately, I've been quite a conversation-ender. People just stare at me when I mention this disaster. "Um, earthquake happened years ago, man. What's the big deal?"
For what it's worth, we have got to get mankind off this planet if our species is to survive. The argument, of course, is that we shouldn't infect other areas of the universe with ourselves.
I had the same reaction. No one gives a shit. No-one thinks we consumers can do anything.
But you can, actually...
First as I did you reduce your consumtion of mains electricity to a mroe sustainable level.
Then you get wind, solar, batteries, a UPS, and a conditioner (cheaper than you might think actually) and stop being a customer.
When enough of us do this, (and when I am off grid, I intend to start a micro business helping others get off grid / reduce their electric consumption) tehn they might realsie we don't want or need this technology.
There is something super smug about listening to others complain about their ever risinig energy bills, while mine keep falling as I get new tech and procedures in place. And of course I can now legitimately bitch about nuclear technology as I don't need, or use it.
I've killed a few conversations, opened the eyes of maybe 1 or 2 people. This world has too much fucked up shit now. When shit falls apart who's gonna take care of these reactors anyway.
This is a handy tool.

I'm thinking of getting a place near Staunton, VA. I dig Shenandoah and small towns. I want to build an earthbag house, heat it w/ a rocket mass heater and build a cob oven. If I only had more time (Burgess Meridith in Twilight Zone comes to mind)
Mssmith,
When I lived in Norther Virgina a lot of us from work would go camping there. Aside for Green and White mountain in New England, Shenandoah is just gorgeous.
Ene News is the ...
Question: are the sea water readings from relatively 'clear water', or from turbid waters? If its turbid they are sampling sediment, not just water, the radioactivity is coming from remobilization of the prior deposited contamination in marine minerals. Radioactive heavy metal cations are readily incorporated into marine clay (google phyllosilicates and marine clays), due to its 'plate' mineral structure of weak Van der Waals bonding between silicate plate sheets. Heavy metals (radioactive ones in this case) are electrically attracted and captured in between the plate-like sheets of the weak bonding.
So re-mobilize the littoral clays, via wind and wave action, or even trawl fishing, and the resulting sea 'water' readings are going to rise sharply in radioactive (clay-sized) components, until the sediment falls out of suspension again several days later.
I pointed this out several times after the meltdowns that we should expect this to regularly recur - for many years to come. There could be new contamination from the reactors, as well, probably there is a chronic leaching process occurring, but if you see a sudden pulse of radioactive contamination, this does not mean it's new radioactive contamination. It may be 99% the remobilizing of the old contamination detritus (As predicted - and that's why I keep telling you the Japanese littoral is where the real problem is, as that's where the most intense initial air-plume debris fell, and the water plume went, and now the chronic leakage is going as well. So every time that marine clay on the littoral is stirred-up, the radiation will spike in the water, and in tissues of critters).
But what's coming from the wells? ... well, ... if its clear water, then its metals in solution. If so that would indicate extensive chronic ground contamination, which is not a surprise (not for me anyway).
And that will be regularly mobilized also, by rainfall input, plus also by seasonal tidal extremes which may intrude and 'wedge' into near-shore ground waters and alter their movement seasonally (though not sure if this can account for the reported tritum spike).
... oh ... and ENENEWS is a hopeless joke GW ... but you should know that by now ... let me guess, they said this meant the world is coming to an end? ... and were hyperventing words to that effect? ... sense of proportion george, sense of proportion.
Element,
And you got -1 for your post. WTF. How do you deal with morons.
I just ignore their crap Rusty and stick it in their faces anyway. ;D
This is some very important info on Fukushima...

How could this ever be covered up...amazing
"Freeze the soil?" Wow...
I stopped eating Alaska salmon ever since all those bald sea lions washed up, not to mention the radiactive boats from Japan floating up on West Coast beaches.
America has the bald eagle, Japan has the bald sea lion.
oh lord…
I crawled up from the bunker and the missus had an episode of “Barney Miller” on the tube.. er, screen on in the kitchen.
It was the 70’s.. New York.. shut down.. chilling.. on several levels.
King Oscar's off the coast of Norway. The Brisling are the best. They say from the frigid waters far north Atlantic.
Between the nuclear discharge from Sellafield in England, the Areeva plant in France that discharges directly - untreated - into the English Channel, and the Chernobyl fallout - every time the wind blows Chernobyl dust, or fire particulate - you might want to reconsider.
Portuguese sardines from Trader Joe are an amazing substitute for the potentially toxic pacific salmon.
aw,crap..
so where is the liquid nitrogen futures exchange ?
Zero Hedge's finest hour when we covered this story. not that competition even bothered to show up (as usual. bunch of scaredy cats.) here's an interesting side story: http://cns.miis.edu/npr/pdfs/133hersman.pdf interesting history...presented in a nice way i might add. unfortunately the same cannot be said for the nuclear power industry: http://www.channelnewsasia.com/news/asiapacific/taiwan-s-fourth-nuclear/... this stuff is worse than nuclear weapons in my view. the weapons never get used. we use the "power thingy" all the time unfortunately. anywho i here if you buy a Tesla you can fuel up for free...forever: http://www.ibtimes.com/heres-where-teslas-free-fuel-charging-network-com... hmmm. i don't see anyone else with that idea.
geez.. wtf.. I know a little electronics, physics, and economics..
where is the hook here?
So what ?
Fukashima will be fine in another 500 years, or so.
Way sooner than our national debt.
No more like 50,000 years or so...We wrote at length in yhe physics forum about thius. A lot of people got kicked out of the forum for telling the truth. You can also read the lunaticsoutpost.com forum on fukushima. Everything that is happening and a lot more that you don't know is happening was described there. This is a lot easier to predict than the economy... Very bad news for the Northern hemisphere...
