Japan Government, TEPCO Deny Fukushima Radiation Tainting Fish

It was the largest radioactive contamination of the sea in history but Japan’s government is disputing a study by a respected international research group suggesting that radiation from the crippled Fukushima nuclear plant is still entering the food chain.

Last month the US-based Woods Hole Institution revealed that about 40 per cent of the fish caught off Fukushima is contaminated with radioactive caesium which is above the government’s own limit.

But Japan’s Fisheries Agency says the contamination is sinking deeper into the seabed and is not entering the food chain, while the nuclear plant operator TEPCO denies any tainted water is leaking from the facility.

Mark Willacy from Radio Australia has more. 

It’s an unfortunate name for a fishing boat from Fukushima, and the irony isn’t lost on the skipper of the Lucky Treasure.

Kozo Endo is a 52-year old fisherman. 

« We can’t sell any of these fish, it’s such a waste. We can only catch them for radiation sampling. Those that are left over – well, all of us working on the boat take them home to eat.”

Once Kozo Endo’s haul of halibut, cod, and greenling would have been bound for market and the crew of the Lucky Treasure would be living up to their boat’s name.

But a recent study by the Woods Hole Oceanographic Institute in the United States suggested that in the 12 months since the Fukushima nuclear meltdowns about 40 per cent of fish caught off the coast there contained radioactive caesium above the government’s safe limit.

This would in turn suggest that radioactive particles have accumulated on the sea floor and are still entering the food chain.

The report’s author is Ken Buesseler.

“There has to be a source, and they’re cooling those reactors quite extensively. Some of that water is getting back into the ocean, either actively being pumped out after some decontamination or through leaks in the building, so not able to contain all of the water that they use to cool.”

There is no doubt that TEPCO, the operator of the Fukushima nuclear plant, has used millions of litres of water to keep the overheating reactors under control and some of that water, especially in the early days of the crisis, leaked into the sea.

TEPCO spokesman Yoshimi Hitosugi.

« We’re doing surveys of the seabed and looking at the things fish eat, such as small organisms like shrimp, but so far we have not found very high levels in either.  So at the present time we are not in a position to clearly understand why there is still radiation being found in fish off Fukushima.”

One theory is that radioactive particles deposited on hills and mountains during the meltdowns are slowly washing into rivers and estuaries, and are then being flushed out into the Pacific before settling on the seabed, where it is absorbed by bottom-feeding fish like greenling.

But Japan’s Fisheries agency says it is not enough to contaminate large numbers of marine species.

Koichi Tahara is the fisheries agency researcher.

« We think the caesium is gradually absorbed into the seabed, and once it’s absorbed it becomes more difficult for it to enter back into living organisms. » 

But if you’re a fisherman like Lucky Treasure skipper Kozo Endo, the damage has already been done and with 36 species of fish still banned from sale, that means his boat is hardly living up to its name.

Fukushima reactors status 24 Nov 2012

The following is the known status as of Saturday morning of each of the six reactors at the Fukushima Daiichi nuclear power plant and the four reactors at the Fukushima Daini plant, both in Fukushima Prefecture, which were crippled by the magnitude 9.0 earthquake and ensuing tsunami on March 11.

 

Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 11, 2011, TEPCO’s facilities including our nuclear power stations have been severely damaged. We deeply apologize for the anxiety and inconvenience caused.
With regard to the accident at Fukushima Daiichi Nuclear Power Station, on April 17, 2011, we have compiled the roadmap towards restoration from the accident and on July 19 we accomplished the Step1 target « Radiation dose is in steady decline ». Then on December 16 we confirmed the accomplishment of the Step 2 target « Release of radioactive materials is under control and radiation doses are being significantly held down ».
In addition, on December 21, 2011, we have compiled the « Mid-to-long-Term Roadmap toward the Decommissioning of Fukushima Daiichi Nuclear Power Units 1-4, TEPCO ».
In addition to the maintenance of the plant’s stable condition, we will implement Mid-to-Long Term countermeasures towards the decommissioning of Fukushima Daiichi Nuclear Power Units 1-4 to enable evacuees to return to their homes as soon as possible and reduce the anxiety of the people in Fukushima and the whole nation as soon as possible.

Below is the status of TEPCO’s nuclear power stations (Fukushima Daiichi and Fukushima Daini).

* The updates are underlined.

[Fukushima Daiichi Nuclear Power Station]
・Unit 1 to 4: Abolishment (April 19, 2012)
・Unit 5 to 6: Outage due to regular inspections before the earthquake

-The mega float currently located in the shallow draft quay in the port will be moved to the north side of the port since all the transport crafts need to get to the shore for the construction to be carried out in the port and carry-in of equipment/materials. As the accumulated water transferred from Units 5-6 Turbine Buildings containing low level of radioactive materials is stored in the mega float, the accumulated water was transferred from the mega float to the temporary tanks installed near Units 5-6 from 10:10 AM to 11:59 AM on November 22 for the purpose of mitigating the risk of radioactive material leakage into the sea. The transfer of the accumulated water is planned to be completed within a month or so.

Asahi: Expert says Japan should be prepared for possibility of M10 quake — “Days of tsunamis” — Only 1 magnitude below asteroid strike

Japan should be prepared for the possibility of a magnitude-10 earthquake, although the chances of a temblor that size are slim, a seismologist said.

[…]

If a temblor of such a scale should strike, the underground rupture would continue for 20 minutes to an hour, meaning tsunami could hit coasts before the shaking subsides.

If a 3,000-kilometer stretch from the Japan Trench to the Kuril-Kamchatka Trench along the Pacific Ring of Fire has a slip of 60 meters, that would constitute a magnitude-10 earthquake, [professor Toru Matsuzawa of Tohoku University] said.

The energy of a magnitude-11 quake, 30 times more powerful than a magnitude-10 temblor, would be equivalent to that of the asteroid impact that is believed to have caused the extinction of the dinosaurs 65.5 million years ago. Such a quake would cause a shift extending more than 20,000 kilometers. Matsuzawa concluded that consideration would not be needed for such an earthquake.

A magnitude-10 quake would be 32 times more powerful than the 9.0 earthquake that hit northeastern Japan in March last year.  […]

A magnitude-10 quake would occur, for example, if an 8,800-kilometer fault along a northern Pacific Rim trench shifts 20 meters.
Matsuzawa says such an earthquake would result in tremors lasting 20 minutes to one hour, and trigger days of tsunamis.

Matsuzawa stresses he’s not saying a magnitude-10 quake would definitely occur. But he notes that Japan was hit by a magnitude-9 earthquake when it had been expecting a maximum magnitude-8, so people should be aware of what could happen.

@iwakamiyasumi [福島民友] イノシシから3万3000ベクレル 野生鳥獣検査で最大 minyu-net.com/news/news/1121… いわき市で捕獲したイノシシは1キロ当たり3万3000ベクレルのセシウムを検出。県によると検出値はこれまでの野生鳥獣の検査で最大


  • イノシシから3万3000ベクレル 野生鳥獣検査で最大

     県は20日、野生鳥獣の肉16点の放射性物質検査結果を発表、放射性セシウムは5点が食品の基準値(1キロ当たり100ベクレル)を超えた。このうち、いわき市で捕獲したイノシシは1キロ当たり3万3000ベクレルのセシウムを検出した。県によると、検出値はこれまでの野生鳥獣の検査で最大。
     県は測定結果について「確かなことは分からない」とするが、「局所的に放射線量が高い場所の物を食べたり、高線量の地区から移動してきたことなどが想定される」としている。県は浜通りと中通りで捕獲したイノシシの肉は食べないよう要請している。このほか、須賀川市のイノシシ、いわき市のカルガモ、福島市のマガモ、桧枝岐村のニホンジカ各1点が基準を超えた。県は新たにいわき地区のカルガモ、県北地区のマガモ、南会津地区のニホンジカについて自家消費を控えるよう要請した。

Nov. 21, 2012 report from Minyu-net :

On 11/20/2012, Fukushima prefecture announced they measured 33,000 Bq/kg of cesium from wild boar in Iwaki city. It was the highest measurement ever.

Prefectural government commented they are not sure about the reason.

From last Sunday’s Guardian: “About 80 per cent of Suzuki’s menu is from Fukushima […] on a quiet street in the Takaido neighbourhood of Tokyo in June last year […] Mr Suzuki’s business plan defied logic: to offer dishes made with ingredients mostly from his home town of Iwaki.”

Debris in Fukushima No. 3 pool is inhibiting water flow, says nuke industry website — ‘Concrete dust’ making it very murky

World Nuclear News “is supported administratively and with technical advice by the World Nuclear Association”; The WNA is “supporting a fast-globalizing nuclear industry”

[…] Concrete dust in the [Unit 3] pool has made the water very murky and the debris inside inhibits the flow of water.

The cover will be constructed to encase the damaged reactor building, protecting it from the weather and preventing any release of radioactive particles during decommissioning work […] it will not be fixed to the reactor building itself, but will be supported on the ground on one side, and against the turbine building on the other.  […]

Tepco aims to remove sufficient debris from unit 3′s used fuel pool to allow the removal of the fuel assemblies to start in fiscal 2014.

The fuel removed from unit 3 will be packaged for transport the short distance to the site’s communal fuel storage pool, although it will need to be inspected and flushed clean of dust and debris. […]

FEATURE: Dog named « miracle » lives on after worst of Fukushima disaster

An old gaunt dog was spotted at a barn in a town in Fukushima Prefecture last August, apparently feeding off the carcasses of cattle left dead in the aftermath of the Fukushima Daiichi nuclear disaster.

 

Naoto Matsumura, who had seen the miserable canine before, thought it a miracle that the dog had managed to survive in Tomioka, a town that was designated as part of the 20-kilometer exclusion zone set up around the crippled power plant in the wake of the disaster.

 

Town residents followed the national government’s order to leave their homes due to high levels of radiation in the area following the disaster, which was triggered by a powerful earthquake and tsunami on March 11, 2011.
