New Fukushima Tank Leaks, Levels As High As 1.8 Sv/h
Tepco announced three more tank leaks at Daiichi. Two are actually existing tank leaks that have worsened and one is a new one. The tank that has the worst change was H3B-Tank 4. It went from a 100 mSv/h detected leak on Aug 22 to a 1.8 Sv/h leak today. Leaks this high will complicate work to deal with the tanks. That level would be considered dangerously high inside the reactor building and would require … Read entire article »

Tritium level in groundwater jumped up 1.8 times much in 2 weeks near reactor 1
Posted by Mochizuki on August 31st, 2013 · No Comments
Following up this article..Cs-134/137 density of reactor1 seawater increasing over 10 times much since this May [URL]
Fukushima Diary is sticking to reactor1 because all kinds of data show the leakage is worsening there but Tepco does hardly report about it.
From Tepco’s data on 8/29/2013, Tritium density in in the seawater has been in the increasing trend since 8/8/2013, when they started measurement.
The location is in the seaside of reactor1, where is on the coastal line. The contamination situation of this area has hardly been announced by Tepco. There is no even impervious wall, so the contaminated groundwater is assumed to be flowing to the sea.
The Tritium density was 23,000,000 Bq/m3 on 8/8/2013. It was increased to be 42,000,000 Bq/m3 on 8/22/2013.
The latest analysis result of 8/29/2013 has not been announced yet.

Another Fukushima worker hospitalized for emergency
Posted by Mochizuki on August 31st, 2013 · No Comments
According to Tepco, a subcontract company worker claimed the physical deconditioning at 9:45 AM of 8/30/2013.
He was treated in the emergency medical care room, and the doctor judged he needs to be hospitalized urgently.
He was sent to the hospital by ambulance at 10:46 AM.
This worker was transferring drum cans in reactor6 tank area.
The medical inspection result hasn’t been announced. No contamination was found on his body.
Groundwater reached the ground surface → Tepco “We won’t use the boring anymore”

↑ The groundwater reaching the ground surface
Following up this article..Groundwater reached 10cm to the surface of the ground on the seaside of reactor2 / Tepco “No details are verified” [URL]
According to Tepco, the groundwater already reached the surface of the ground on 8/27/2013.
The reached water was the mixture of groundwater and the chemical material injected to underground, which will become the impervious wall.
The location is in one of the borings of reactor2 seaside.
Tepco is building more impervious wall on the land side of the seaside. (cf, Tepco started isolating the seaside of reactor2 by underground walls [URL 2])
Tepco explains the groundwater level is affected by the construction of this land side impervious wall.
They are planning to abandon this boring and will use alternative observation hole like they labelled the thermometers as “Disordered” in reactor2 when those indicated the increasing temperature.
[Column] Summary of Fukushima – Is tank water safe ?
Posted by Mochizuki on August 31st, 2013 · No Comments
Because now the contaminated water keeps increasing, Tepco has to make tanks infinitely. Sure tank deteriorates. Some of them have started leaking. I think more tanks will leak soon.
I heard a reporter from a (very) major media comment the tank water is not dangerous because it’s filtered. I even heard an anti-nuclear activist say so.
Is this true ? Here I’d love to explain the situation.
Q. Is the tank water safe ?
A. The answer is No.
Q. but it’s filtered water no ?
A. “Radiation” has variety kinds of the bad stuff. They only filter a part of the bad stuff. The rest remains in it.
Q. Why they don’t reuse the water ?
A. They do. This is why the unfilterable stuff gets more concentrated.
Q. Why do the tanks leak ?
A. The reason is not even verified. However, the tanks are supposed to last only for 5 years. Plus, it contains highly radioactive water, outside, near the sea, on the crippled land. I think that’s enough to explain.
Q. How many tanks are in Fukushima nuclear plant ?
A. 1,000. 350 of them are especially weak because they are not welded. and it’s increasing.
Q. Why did Tepco build so many weak tanks ?
A. They say because they didn’t have time. Some people suspect they wanted to save money.
Q. Will Tepco have to build the tanks forever ?
A. They’ll run out of the tanks this November ~ December because the contaminated water increases faster than they build the tanks. After then, nobody has a plan about where to stock the increasing contaminated water.
High level of Cs-134/137 detected on the top of reactor3 again / Spread by the wind
Posted by Mochizuki on August 31st, 2013 · No Comments
Fukushima Diary reported Cesium-134/137 level jumped up 10~1,000 times much as average on the top of reactor3 on 8/23/2013. [URL]
On 8/29/2013, higher level of Cs-134/137 was measured in the dust of the top of reactor3. The top floor (Operation floor) of reactor3 was already covered with the antiscattering agent. It is unlikely that the Cs-134/137 level in the dust was picked up due to the debris removal on the building.
Cs-134 density was 8.1×10^3 Bq/m3, Cs-137 density was 1.7×10^4 Bq/m3.
The wind blew from the east at this time (2m/sec), and the significant level of Cs-134/137 was also measured in two locations of downwind.
Cs-134 : 1.1 ~ 3.1 Bq/m3
Cs-137 : 2.6 ~ 9.1 Bq/m3
There is a possibility that the radiation level of the gas from reactor3 is picking up for some reason, and it’s spreading by the wind.
[Breaking] 4 more leakages found from the tanks / Max as 1.8 Sv/h
Posted by Mochizuki on August 31st, 2013 · No Comments
According to Tepco, they found 4 more leakages of the contaminated water tanks.
2 of the leakages are the same locations as where they detected 70 ~ 100 mSv/h on 8/22/2013.
(cf, [More tank leakage] 100 mSv/h detected beside another tank area of the same type [URL])
However, the radiation levels jumped up from 100 mSv/h to 1,800 mSv/h and from 70 mSv/h to 220 mSv/h (γ & β).
Tepco is still under investigation of the cause.

Fukushima radioactive leak causes the sea off Japan coast to boil
Photo: EPA
The sea is boiling off of the coast of Fukushima, Japan, and the picture of this devastating phenomenon has recently been called the photo of the day by . While it certainly can’t be good for any plant or animal life left off of the coast of Japan, it might have even worse consequences for the North American continent. If Fukushima radiation keeps leaking, the boiling seas are likely to spread all the way across the Pacific Ocean to the West Coast of the US causing massive environmental catastrophe.
A Twitter photo showing a “boiling sea” off the coast of Japan, near the Fukushima nuclear power plant with radiation leaks, has gone viral online.
The news of the boiling sea followed the devastating report from last week when Tokyo Electric Power Co (TEPCO) said 330 tons of highly radioactive water leaked from a storage tank at the facility.
Arnie Gundersen, a former nuclear industry executive who has coordinated projects at 70 nuclear power plants around the United States says “the problem is going to get worse,” and continues on to state “Radioactive water is leaking out of this plant as fast as it is leaking in.”
It is noteworthy that TEPCO and Japan have continuously downplayed news about the severity of the situation since 2011, so it is logical for experts to be concerned that the problem is a good deal worse than either Tepco or the Japanese government are .
“The quantities of water they are dealing with are absolutely gigantic,” said Mycle Schneider, who has consulted widely for a variety of organisations and countries on nuclear issues. “What is the worse is the water leakage everywhere else – not just from the tanks. It is leaking out from the basements, it is leaking out from the cracks all over the place. Nobody can measure that."
According to Gundersen, the deluge of toxic water into the Pacific has already contaminated the ocean and this will be the last year he eats west coast fish.
Gundersen says that halfway across the Pacific, scientists are measuring cesium levels that are 10 times higher than normal.
The ramifications of this is not only for ocean life, but the economy as well since tens of thousands of people depend on the money made directly and indirectly from Pacific Ocean jobs and the seafood that comes from the west coast, which is going to be hit hard by Fukushima radiation.

Radioactive water may contaminate entire Pacific Ocean in 6 years
This graphic shows the gradual contamination of the Pacific Ocean due to leaks of radioactive water from the crippled Fukushima nuclear plant in Japan.
The simulation, which was run by a German marine research institute, shows the ENTIRE Pacific waters being polluted by radioactive water in just six years.
Although the results failed to grab attention when first released last year, experts now fear that the hypothesis may become a scary reality, after the Japanese government recently admitted that some 3-hundred tons of radioactive water have leaked into the ocean everyday.
Mitsuhei Murata, a former Japanese ambassador to Switzerland criticized the Japanese government and the operator of the crippled nuclear plant, Tokyo Electric Power Corporation for its handling of the situation.
"TEPCO recently admitted to leaks of radioactive water. The amount is much greater than what the simulation had taken into account."
The international community has also voiced concerns over the issue, but Tokyo meanwhile, is busy drumming up support for its bid in hosting the 2020 Olympics.
"2020 Tokyo Let's do well."
Murata stressed the fact that Japan does not realize the gravity of the issue is more outrageous.
"If Japan cannot secure the safety of its own nation,… it is being insincere in hosting an international event like the Olympics. It should step out of the race."
A Russian nuclear research center had also advised TEPCO to take measures two years ago, just after the accident broke out, but Japan turned down the suggestion.
It's now been two years and five months since the nuclear crisis, and Tokyo has finally set out to deal with the problem.
However, experts say that it may be TOO LATE.
The former ambassador also warned that Japan may lose its rights in its Exclusive Economic Zone,… if it fails to block the leakage into the 2-hundred nautical mile zone.

Fukushima radiation could reach US coast in five years
Radioactive water from the Fukushima nuclear reactors in Japan could reach the US West Coast in the next 5–6 years, doubling the radioactivity of US coastal waters, according to simulations carried out by German oceanographers.
Claus Böning, Erik Behrens and colleagues from the Helmholtz Centre for Ocean Research in Kiel used global ocean circulation models to simulate the movement of a tracer which was continuously injected into Japanese coastal waters over several weeks. They then modelled its spreading and dilution in the Pacific Ocean for 10 years.
“We were of course not surprised that there is a mixing effect, but we were surprised at how quickly the tracer spread,” Claus Böning, co-author of the study, told environmentalresearchweb. “Within one year it will have spread over the entire western half of the North Pacific and in five years we predict it will reach the US West Coast.”
However, Böning points out that, due to considerable mixing and dilution, the level of radioactivity reaching the US will be much lower than that released by the Fukushima plant. “The levels of radiation that hit the US coast will be small relative to the levels released by Fukushima,” he said. “But we cannot estimate accurately what those levels will be because we do not know for certain what was released by Fukushima.”
Tentatively assuming a value of 10 petabecquerel (PBq) for the net137Caesium (Cs) input during the first weeks after the Fukushima incident, the simulation suggests a rapid dilution of peak radioactivity values to about 10 Bq/m³ during the first 2 years, followed by a gradual decline to 1–2 Bq/m³ over the next 4–7 years. The total peak radioactivity levels would then be about twice the pre-Fukushima values. “While this may sound alarming, these levels are still lower than those permitted for drinking water,” said Böning.
The team found that using models with different resolutions to simulate eddy fields gave different results. “This shows that high-resolution models are needed,” said Böning. “We also did not model biological processes which might lead to accumulation of 137Cs in areas of high biological productivity, and potentially affect vertical tracer distributions due to adherence to sinking particles.”
The researchers published their work in Environmental Research Letters (ERL).
