Tepco unable to halt tainted water flowing into tunnels at Fukushima

Attempt to stop water flowing into trench at Fukushima plant fails
Around 5,000 tons of contaminated water from the turbine building is in the trench, and critics have pointed out the possibility of it escaping into the ocean.

Originally TEPCO planned to freeze the water at the point where the turbine building and the trench meet in order to stop the flow of water, after which it planned to remove the water from the trench. However, the water was insufficiently frozen to stop the flow, and while an effort continued until Nov. 6 to fill in the gaps in the ice with special cement, this effort also failed to provide a complete seal.

While the water remains in the trench, TEPCO cannot create a planned underground wall of frozen soil around the No. 1 through 4 reactor buildings to stop water leakages. TEPCO is considering filling in the trench by pouring in cement as it removes the built up water. Discussion on the particulars of this strategy is to be held at a meeting of the Nuclear Regulation Authority on Nov. 21.

I love sensationalistic journalism ....always using "tons of water" to get a higher shock factor number

5,000 tons of water is only about 1,200 gallons.

No!

There is a problem in your Calculation!

Anyway, 5.000 Tones of Water are just Peanuts.

But why it was not working?
This Water is not warm and the flow inside of the Tube is low.

This Tube is 500Cm in Diameter.

glad you're here.... just finishing up a joint report on this...

your minimization effortsa are astounding...

you picked the wrong night atom-dick

the report is making japanese news and includes the failures being announced by the current head of plant:

"the current situation must me attended to as a priority"

the new fukushima representative calling for the showing of all the faults; calling for the closure of Daichii no2; the delay of transporting all of the radioactive crap from elsewhere back to fukushima prefecture...


you my idiot, have just bit off more than you can chew....

full report inbound....

Contaminated water swamps Fukushima No. 1 cleanup

[link to www.japantimes.co.jp]
AP

More than three years into the massive cleanup of the Fukushima No. 1 power plant, only a tiny fraction of the workers are focused on key tasks such as preparing for the dismantling of the wrecked reactors and removing radioactive fuel rods.

Instead, nearly all the workers at Fukushima No. 1 are devoted to a single, enormously distracting problem: coping with the vast amount of contaminated water, a mixture of groundwater running into recycled water that becomes contaminated and leaks after being pumped into the reactors to keep their melted cores from overheating.

A number of buildings housing water treatment machines and hundreds of huge blue and gray industrial storage tanks to store the excess water are rapidly taking over the grounds at the plant, which saw three of its six reactor cores suffer meltdowns from the 3/11 quake and tsunami. Workers were still building more tanks during a visit to the complex Wednesday by a group of foreign media.

“The contaminated water is a most pressing issue that we must tackle. There is no doubt about that,” said Akira Ono, head of the plant. “Our effort to mitigate the problem is at its peak now. Though I cannot say exactly when, I hope things start getting better when the measures start taking effect.”

The numbers tell the story:

6,000 workers

Every day, about 6,000 workers pass through the guarded gate of Fukushima No. 1, located on the Pacific coast, two to three times more than when it was actually generating electricity.

On a recent workday, about 100 workers were dismantling a makeshift roof over one of the reactor buildings, while about a dozen others were removing fuel rods from a cooling pool. Most of the rest were dealing with contaminated water-related work, said Tatsuhiro Yamagishi, a spokesman for plant operator Tokyo Electric Power Co.

The work threatens to exhaust the supply of workers for other tasks, since they must stop working when they reach annual radiation exposure limits. Experts say it is crucial to reduce the amount and radioactivity of the contaminated water to decrease the risk of exposure to workers and the environmental impact before the decommissioning work gets closer to the highly contaminated core area.

40 years

The plant has six reactors, three of which were offline when disaster struck on March 11, 2011, a magnitude-9.0 earthquake that triggered huge tsunami that swept into the plant and knocked out its backup power and cooling systems, leading to core meltdowns in the three active reactors.
Decommissioning and dismantling all six of the reactors is a delicate, time-consuming process that includes removing the melted fuel from a highly radioactive environment as well as all the extra fuel rods, which sit in cooling pools situated at the top of the reactor buildings.

The entire job still requires finding out the exact conditions of the melted fuel debris and developing remote-controlled and radiation-resistant robotics to deal with them, and the work is expected to take at least 40 years.

500,000 tons

The main problem is an abundant inflow of groundwater into the contaminated water that doubles the volume and spreads it to vast areas of the compound. Workers have jury-rigged a pipe-and-hose system to continuously pump water into the reactors to cool the clumps of melted fuel inside.

The water becomes contaminated upon exposure to the radioactive fuel, and much of it pours into the reactor and turbine basements, and maintenance trenches that extend to the Pacific Ocean. The plant recycles some of the contaminated water as cooling water after partially treating it, but groundwater is also flowing into the damaged reactor buildings and mixing with contaminated water, creating a huge excess that needs to be pumped out.

So far, more than 500,000 tons of radioactive water have been stored in nearly 1,000 large tanks that workers have built, which now cover most of the sprawling plant premises. After a series of leaks from the storage tanks last year, they are now being replaced with costlier welded tanks.
That dwarfs the 9,000 tons of contaminated water produced during the 1979 partial meltdown at Three Mile Island in the United States. In that incident, it took 14 years for the water to evaporate, said Lake Barrett, a retired U.S. nuclear regulatory official who was part of the early mitigation team there and has visited Fukushima No. 1.
“This is a much more complex, much more difficult water management problem,” Barrett said.

¥10 trillion

An estimated ¥2 trillion will be needed just for decontamination and other mitigation of the water problem. Altogether, the entire decommissioning process, including compensation for area residents, reportedly will cost about ¥10 trillion.

All this for a plant that will never produce a kilowatt of energy again.

The work threatens to exhaust the supply of workers for other tasks, since they must stop working when they reach annual radiation exposure limits. About 500 workers are digging deep holes in preparation to build a taxpayer-funded ¥32 billion underground “frozen wall” around the four reactors and their turbine buildings to try to keep the contaminated water from seeping out.

Tepco is developing systems to try to remove most radioactive elements from the water. One, the Advanced Liquid Processing System (ALPS), has been trouble-plagued, but utility officials hope to achieve a daily capacity of 2,000 tons when it enters full operation next month. Officials hope to be able to treat all contaminated water by the end of March, but that is far from certain.

Thread: Radionuclides and Health Risks for the Citizens of Fukushima City, Tokyo, and Osaka after the 2011 Nuclear Accident

You may love it, but I'm ashamed to see an American flag by your name. What "Murika"?

5,000 tons
x2,000 pounds per ton

= 10,000,000 pounds
/ 8 pounds per gallon

= 1,250,000 gallons

The 5,000 tons figure is for average people like you who don't understand math. 5,000 tons sounds like nothing compared to 1,250,000 gallons or 4,750,000 litres.

("it"'s not an american), trust me....

same addy that chimes in with atom-boy from time to time to add an "american" perspective and support ... *cough*

Actually in our System it is 5.000.000 Liters but not 4.750.000 Liters,
but it is still Peanuts
(compared to the Initial Release)

Do you get tainted water when like your dick leaks pee and it runs down toward your asshole. That's funny!

obfuscating the point.. go back to the press releases with the real amounts instead of debating non-data....

Keep up the good work CitizenPerth.

It is noty up to you to decide what i have to do

Wakata (555)

Next they will turn all that water into hydrogen to power the new Toyota...

Or they will start putting Highly Mineralized Water Bottles on the market!

They have no solution.

Thanks CP, I appreciate it when you put some light on the subject.
I like watching the cockroaches scurry back into the darkness.

IT'S STILL RADIOACTIVE WATER Compared to the Initial Release OF RADIOACTIVE WATER

So What?

Nobody welcomed this Accident!

What are your Uranium, Oil Sand, Coal, etc. Mines doing?
What is going on with the Tailings of it?
How do you care about the Native People?
Do you asked them?

how about cleaning it up?.. dickhead... how many times do you need to be offered help....

you need to send these in:



probably work better then all your other failed ones...

how's that ice all working out for you?

@ Cp,

your Australian Mines are booming because of the possible Restart of
the Japanese Nuclear Plants, and you do nothing, as usual

This so called accident of yours was avoidable!

Its like speeding in a car at 120 miles an hour, in a 55 mph work zone. One wrong move and ....oops, there's an accident (NO, IT WAS TOTALLY AVOIDABLE)!

Seems like the people who are responsible for building the nuclear power plants didn't listen to your Elders, who warned them about building below the high water mark. -
And you call it an accident?
Predictable, Probabilities, Perpetuate the Problem.

This "Accident" should be used as a deterrent for starting up or building any new nuclear power plants anywhere in the world, but some just won't learn.


As for the rest of your insinuations, lets stay on topic, shall we....Your thread is titled "Tepco unable to halt tainted water flowing into tunnels at Fukushima"

If you want to start another thread on Mining, Or about Alaskan Natives, by all means, please do.

Those are bad as well, but not leaking radiation directly and indirectly into the primary system that gives the living things food.

Our mines are being closed thanks

1. to our ongoing work and
2. thanks to you idiots.. you lost all sales... BAHAAHAHHAH

so you kind of helped in a twisted manner...

got a new job lined up yet.. oh wait, you were homeless and illegal... best of luck...

(doesn't even speak japanese properly)


do your mommy and daddy know what you have been doing?.. or indeed, do they exist?

dear atom-twat,

i have told you and told you... don't insult other users without a basis... reported for abusive.. dear god yer a bit slow really......

also (food for thought), you were the one that started a bait thread.. go live with your epic failure..... again.....

reminds me of.. umm lemmie think of a small example... oh!.. an ice wall!....
