TEPCO Readies For Extremely Dangerous, Never Before Attempted Operation To Remove 400 Tons Of “Spent” Nuclear Fuel At Fukushima

Poolside: The spent-fuel pool of reactor 4 at the crippled Fukushima No. 1 nuclear power plant

Oldspeak: “The operation to begin removing fuel from such a severely damaged pool has never been attempted before.

The complex has recently seen a series of setbacks, including highly toxic water gushing from storage tanks into the Pacific. The incidents, many of them caused by human error, have added to concerns about operator Tepco’s ability to safely dismantle the No. 1 plant” –Japan Times

“Ummm…. this can’t be good. Let me get this straight. TEPCO is going to attempt an extremely dangerous and never before tried operation that it originally planned to do in 2 years in 1 YEAR? So they’re going to rush through the job, and expect everything to go off (pun intended) without a hitch?! Given its record of mismanagement, unpreparedness, false information, human error and breathtaking incompetence handling this ongoing and ever worsening ecological and environmental catastrophe, i don’t understand why  responsibility is still being left to TEPCO to do anything!  Why would anyone with knowledge of the situation have ANY confidence that TEPCO could execute this operation successfully?!?! Sure they’re accepting international help, 2 years later, but this is an unprecedented event. A triple-meltdown, where nuclear cores have been lost, and there is no existing means to contain the perpetual radiation release. Expect a potentially life altering fuck up to kill billions of people. There are just too many ways this shitshow can go sideways real fast. ” –OSJ

U.S. To Help With No. 1 Shutdown

Dangerous Operation Planned For Fukushima Plant

By RT:

Fukushima operator TEPCO is getting ready for its toughest and the most dangerous clean-up operation. In November it will try to remove 400 tons of spent fuel from plant’s Reactor No. 4. But even a little mistake may result in a new nuclear disaster.

The operation is scheduled to start in the beginning of November and be completed by around the end of 2014.

Under normal circumstances, the operation to remove all the fuel would take about 100 days. TEPCO (Tokyo Electric Power Co) initially planned to take two years, but reduced the schedule to one year in recognition of the urgency, as even a minor earthquake could trigger an uncontrolled fuel leak.

During this period TEPCO plans to carefully remove more than 1,300 used fuel rod assemblies, packing radiation 14,000 times the equivalent of the Hiroshima nuclear bomb, from their cooling pool.

The base of the pool where the fuel assemblies are situated is 18 meters above ground and the rods are 7 meters under the surface of the water.

TEPCO’s first task is to remove the debris from the Reactor No. 4 fuel pool.

Then, one by one, the fuel rods will be removed from the top store of the damaged building using a crane suspended above the crippled reactor.

Previously a computer-controlled process, this time it has to be done completely manually. And this is what makes this removal operation extremely dangerous.

The fuel rods must be kept submerged and must not touch each other or break.

“The operation to begin removing fuel from such a severely damaged pool has never been attempted before. The rods are unwieldy and very heavy, each one weighing two-thirds of a ton,” fallout researcher Christina Consolo earlier told RT.

Should the attempt fail, a mishandled rod could be exposed to air and catch fire, resulting in horrific quantities of radiation released into the atmosphere. The resulting radiation will be too great for the cooling pool to absorb as it simply has not been designed to do so.

In the worst-case scenario, the pool could come crashing to the ground, dumping the rods together into a pile that could fission and cause an explosion many times worse than in March 2011.

“The worst-case scenario could play out in death to billions of people. A true apocalypse,” Consolo said.

Reactor No. 4 contains 10 times more Cesium-137 than Chernobyl did. This lets scientists warn that in case of another nuclear disaster, it will be the beginning of the ultimate catastrophe of the world and the planet.

“It will be one of the worst, but most important jobs anyone has ever had to do. And even if executed flawlessly, there are still many things that could go wrong,” Consolo said.

The World Nuclear Report, released in July 2013, said “the worst-case scenario” will require evacuation of up to 10 million people within a 250-kilometer radius of Fukushima, including a significant part of Tokyo.

Although some experts are skeptical, TEPCO is confident the operation will be a success. Last year two fuel rods were successfully removed from the pool in a test operation, but back then rod assemblies were empty and posed a far smaller threat.

The operation will be just one installment in the decommissioning process for the plant, and is forecast to take about 40 years and cost $11 billion.

TEPCO, responsible for the clean-up, is struggling to cope with the aftermath of the nuclear disaster, but with the crisis over radiation-contaminated water at the plant, it has been criticized for its ad hoc response to the disaster. In August TEPCO pleaded for overseas help to contain the radioactive fallout, after 18 months of trying to control it internally.

The Japanese government was also ordered to take a more active role in controlling the overflow of radioactive water being flushed over the melted reactors in Units 1, 2 and 3 at the plant.

Three of the Fukushima plant’s nuclear reactors were damaged by an earthquake-triggered tsunami on March 11, 2011, which led to a nuclear disaster. The plant has been accumulating radioactive water ever since. The government imposed a 20-kilometer ‘no-go’ zone around the plant area.

Radiation Levels At Crippled Fukushima Nuclear Plant Soar Over 20% To Record High; Hits 2,200 mSv And Rising

Tepco faces a major challenge to safely store contaminated water at Fukushima

Oldspeak: “Meanwhile, news from the Department Of Existential Threats…  Years later, the ongoing global ecological disaster that keeps on giving is giving ALOT MORE lately. And still no one knows how to stop it. Now there’s talk of freezing the earth around the plant creating an “ice wall” to prevent further groundwater contamination. Riiiiight… Given the fact that radioactive water has been continuously leaking from the reactors, spent fuel pools & multiple storage tanks for years into the surrounding ground, air, and ocean, while defects in the storage tanks make it probable that they’ll ALL leak at some point, this seems like  too little too late, and a colossal waste of time and energy. The overarching fact of the matter is there is no safe way to store nuclear waste products. This catastrophe will only get worse as time passes, and there’s not much anyone can do about it. Thankfully, the silence on this crisis is being broken ” –OSJ

Record Radiation Readings Near Fukishima Contaminated Water Tanks

By BBC News Asia:

Radiation levels around tanks storing contaminated water at Japan’s crippled Fukushima nuclear plant have risen by a fifth to a new high, officials say.

Ground readings near one set of tanks stood at 2,200 millisieverts (mSv) on Tuesday, the plant operator and Japan’s nuclear authority said.

Saturday’s reading was 1,800 mSv.

Last month, plant operator Tokyo Electric Power Company (Tepco) said it had found highly contaminated water leaking from a storage tank.

Other leaks have also been reported, prompting the government on Tuesday to pledge 47bn yen ($473m, £304m) in funding to tackle the problem.

The spike in radiation levels found on Tuesday was in the same area where the 1,800 mSv level was detected on Saturday, a spokeswoman from Tepco told Bloomberg.

The readings are thought to be high enough to provide a lethal radiation dose to someone standing near contaminated areas without protective gear within hours.

But Japan’s Nuclear Regulation Authority (NRA) also said the areas were easily contained.

‘Drastic measures’

The earthquake and tsunami in March 2011 knocked out cooling systems to reactors at the Fukushima plant, three of which melted down.

Water is now being pumped in to cool the reactors, but storing the resultant large quantities of radioactive water has proved a challenge for Tepco.

The process creates an extra 400 tonnes of contaminated water every day, which must be stored in temporary tanks.

But leaks of contaminated water, both from the tanks, pipes and through damaged structures, have been a persistent problem. Groundwater from the hills surrounding the plant also flows down and into the radioactive areas.

Under the government plan announced on Tuesday, a wall of frozen earth will be created around the reactors using pipes filled with coolant. This aims to prevent groundwater coming into contact with contaminated water being used to cool fuel rods.

Water treatment systems would also be upgraded to tackle the build-up of contaminated water, officials said.

On Wednesday, Japanese Prime Minister Shinzo Abe told journalists in Tokyo that the government was willing “to take drastic measures of a maximum scale” to resolve the issue ahead of the 2020 summer Olympic Games.

“We are aware of concerns over the issue of contaminated water leakages at Fukushima, the government will take charge and will definitely resolve this problem,” he said.

Tokyo is a candidate as a host nation for the Olympics, and the decision is expected in days.

West Coast Of North America To Be Hit Hard By Fukushima Radiation That Could Be 10 Times Higher Than In Japan

In Uncategorized on August 27, 2013 at 5:29 pm

https://i0.wp.com/iprc.soest.hawaii.edu/news/marine_and_tsunami_debris/2011/11_04_maximenko_tsunami_debris/map_of_trajectory_med.jpgOldspeak” This ongoing and uncontrolled ecological catastrophe continues, with no end in sight. Untold billions of tons of water are being dumped into the Pacific ocean by the Japanese. The contamination is expected to get worse as time passes and impact Baja California and other North American west coast hotspots. And no one knows how to fix it. “Last year, scientists from the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Marine Environmental Laboratory and 3 scientists from the GEOMAR Research Center for Marine Geosciences showed that radiation on the West Coast of North America could end up being 10 times higher than in Japan“. These are reputable research scientists saying this. Yet, universal silence in state media. Citizens from Hawaii to Alaska to Baja should be demanding information about what’s going on and what’s being done in response to the threat. The civil war in Syria is infinitesimally less threatening to the millions of people to be affected.” –OSJ

Radiation Levels Will Concentrate in Pockets In Baja California and Other West Coast Locations

An ocean current called the North Pacific Gyre is bringing Japanese radiation to the West Coast of North America:

North Pacific Subtropical Convergence Zone FDA Refuses to Test Fish for Radioactivity ... Government Pretends Radioactive Fish Is Safe

The leg of the Gyre closest to Japan – the Kuroshio current – begins right next to Fukushima:

Kuroshio Current - Colour show water speed.  Blue slowest; red fastest

While many people assume that the ocean will dilute the Fukushima radiation, a previously-secret 1955 U.S. government report concluded that the ocean may not adequately dilute radiation from nuclear accidents, and there could be “pockets” and “streams” of highly-concentrated radiation.

The University of Hawaii’s International Pacific Research Center created a graphic showing the projected dispersion of debris from Japan (see pic at top)

Last year, scientists from the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Marine Environmental Laboratory and 3 scientists from the GEOMAR Research Center for Marine Geosciences showed that radiation on the West Coast of North America could end up being 10 times higher than in Japan:

After 10 years the concentrations become nearly homogeneous over the whole Pacific, with higher values in the east, extending along the North American coast with a maximum (~1 × 10−4) off Baja California. 

***

With caution given to the various idealizations (unknown actual oceanic state during release, unknown release area, no biological effects included, see section 3.4), the following conclusions may be drawn. (i) Dilution due to swift horizontal and vertical dispersion in the vicinity of the energetic Kuroshio regime leads to a rapid decrease of radioactivity levels during the first 2 years, with a decline of near-surface peak concentrations to values around 10 Bq m−3 (based on a total input of 10 PBq). The strong lateral dispersion, related to the vigorous eddy fields in the mid-latitude western Pacific, appears significantly under-estimated in the non-eddying (0.5°) model version. (ii) The subsequent pace of dilution is strongly reduced, owing to the eastward advection of the main tracer cloud towards the much less energetic areas of the central and eastern North Pacific. (iii) The magnitude of additional peak radioactivity should drop to values comparable to the pre-Fukushima levels after 6–9 years (i.e. total peak concentrations would then have declined below twice pre-Fukushima levels). (iv) By then the tracer cloud will span almost the entire North Pacific, with peak concentrations off the North American coast an order-of-magnitude higher than in the western Pacific.

(“Order-of-magnitude” is a scientific term which means 10 times higher.  The “Western Pacific” means Japan’s East Coast.)

In May, a team of scientists from Spain, Australia and France concluded that the radioactive cesium would look more like this:
And a team of top Chinese scientists has just published a study in the Science China Earth Sciences journal showing that the radioactive plume crosses the ocean in a nearly straight line toward North America, and that it appears to stay together with little dispersion:

On March 30, 2011, the Japan Central News Agency reported the monitored radioactive pollutions that were 4000 times higher than the standard level. Whether or not these nuclear pollutants will be transported to the Pacific-neighboring countries through oceanic circulations becomes a world-wide concern.

***

The time scale of the nuclear pollutants reaching the west coast of America is 3.2 years if it is estimated using the surface drifting buoys and 3.9 years if it is estimated using the nuclear pollutant particulate tracers.

***

The half life of cesium-137 is so long that it produces more damage to human. Figure 4 gives the examples of the distribution of the impact strength of Cesium-137 at year 1.5 (panel (a)), year 3.5 (panel (b)), and year 4 (panel (c)).

***

It is worth noting that due to the current near the shore cannot be well reconstructed by the global ocean reanalysis, some nuclear pollutant particulate tracers may come to rest in near shore area, which may result in additional uncertainty in the estimation of the impact strength.

***

Since the major transport mechanism of nuclear pollutants for the west coast of America is the Kuroshio-extension currents, after four years, the impact strength of Cesium-137 in the west coast area of America is as high as 4%.

Note: Even low levels of radiation can harm health.

Japan Is Poisoning The U.S., Canada, Other Countries By Burning Highly Radioactive Debris

Fukushima to Burn Highly-Radioactive Debris

Fukushima will start burning radioactive debris containing up to 100,000 becquerels of radioactive cesium per kilogram. As Mainchi notes:

The state will start building storage facilities for debris generated by the March 2011 tsunami as early as May at two locations in a coastal area of Naraha town, Fukushima Prefecture, Environment Ministry and town officials said Saturday.

***

About 25,000 tons of debris are expected to be brought into the facilities beginning in the summer, according to the officials.

***

If more than 100,000 becquerels of radioactive cesium are found per kilogram of debris, the debris will be transferred to a medium-term storage facility to be built by the state. But if burnable debris contains 100,000 becquerels of radioactive cesium or less, it may be disposed of at a temporary incinerator to be built within the prefecture, according to the officials.

Within the 20-km-radius no-go zone spanning across Naraha and five other municipalities along the coast, debris caused by the magnitude 9.0 quake and the subsequent tsunami has amounted to an estimated 474,000 tons, much of remaining where it is.

How much radiation is that?

It is a lot.

Nuclear expert Arnie Gundersen has said that much lower levels of cesium – 5,000-8,000 bq/kg (20 times lower than what will be allowed to be burned at Fukushima) – would be sent to a special facility in the United States and buried underground for thousands of year. See this and this.

It is comparable to the levels of radioactivity found within the Chernobyl Exclusion Zone. See this and this.

And even the Japanese – who have raised acceptable levels of radiation to absurd levels – would normally demand that material with this radioactivity be encased in cement and buried:

According to plans by the Ministry of Environment, if the radioactive cesium concentration is less than 8,000 Bq/kg, then it is possible to dispose of it by burying it. Rubble that has 8,000 ~ 100,000 Bq must be encased in cement in order to prevent contact with water before being dumped. For rubble that exceeds 100,000 Bq, it must be encased in concrete walls and stored temporarily. The disposal place must be approved of by the Prefectural Governor.

In addition, some allege that debris surpassing 100,000 bq/kg of cesium will be burned, after being mixed with less-radioactive materials.

And many of the incinerators are located smack dab in the middle of crowded cities, and are not equipped to contain radiation.

Other Parts of Japan Are Also Burning Radioactive Debris

And it’s not just Fukushima.

Tokyo and many other areas in Japan are burning radioactive debris as well. And see this.

Burning to Continue for for Years

Mainichi reports that the radioactive debris will be burned for years … through at least March 2014.

Poisoning Other Countries

Burning radioactive debris does not destroy the radioactivity. It merely spreads it.

Gundersen says that radioactivity from the burnt debris will end up not only in neighboring prefectures, but in Hawaii, British Columbia, Oregon, Washington and California. Gundersen said that burning radioactive debris is basically re-creating the Fukushima disaster all over again, as it is releasing a huge amount of radioactivity which had settled on the ground back into the air.

Steven Starr – Senior Scientist, Physicians for Social Responsibility, and Director of the Clinical Laboratory Science Program at the University of Missouri-Columbia, who has advised numerous countries on issues of nuclear non-proliferation – writes:

Burning radioactive debris will only serve to further randomly spread radiation across Japan, as well as the rest of the world. Not only will this lead to more morbidity and mortality within Japan, but it will further complicate epidemiological studies of the Fukushima disaster. Raising “acceptable” levels of radioactive fallout is a false solution to a serious problem. It is possible for the government authorities to do this because radiation is invisible to us, and at lower doses, the consequences of exposure do not manifest themselves for some time . . . thus it is a poison that is easy to hide and ignore. Sadly, the children of Japan will be those most seriously affected by this man-made environmental catastrophe.

It is bad enough that radiation from Fukushima is spreading across the Pacific to the United States through air and water, that the Japanese are underplaying the enormous threat posed by the spent fuel pools, and that the Japanese have engaged in a massive cover-up of the severity of the Fukushima crisis. But intentionally burning radioactive debris to try to cover up the problem – and spreading radiation worldwide in the process – is an entirely separate affront.

Postscript:  In addition to burning radioactive debris, Japan intends to build tents over the leaking Fukushima reactors. While this sounds like a way to contain the radiation, it would actually funnel it straight up and spread it globally:

My reaction [to the announcement that the Fukushima nuclear operator would build giant tents over the reactors] was hope that the tents would at least keep radiation from spreading worldwide through the air, even if they didn’t do anything to prevent contamination of Japan’s groundwater or the Pacific Ocean.

But nuclear expert Arnie Gundersen says that the tents – while helping to protect workers at Fukushima – will actually increase the dispersion of radioactive gases. Specifically, Tepco will pump radiation out through stacks, which will push radiation up to a higher elevation, dispersing it even further around the world.

Radiation Detected In Massachusetts Rainwater As Fukushima Crisis Worsens

In Uncategorized on March 28, 2011 at 5:46 pm

Oldspeak:” You can bet dollars to doughnuts, Massachusetts isn’t the only place irradiated rain has fallen in the U.S. The same script was used in the BP disaster. Underreporting, withholding of vital facts by authorities and minimizing of the threat. We still don’t know the actual repercussions from that disaster, and likely won’t for years to come. This disaster is an exponentially greater threat and the damage can’t be hidden in the ocean.  This environmental damage will last for 1,000s of years, and it’s far from “localized” to Japan. And the repercussions will be felt for countless generations to come in ways that aren’t yet apparent.”

By Mike Adams @ Natural News:

The Fukushima crisis continues to worsen by the day, with nuclear experts around the world finally realizing and admitting we’ve all been lied to. “I think maybe the situation is much more serious than we were led to believe,” said Najmedin Meshkati of the University of Southern California, in a Reuters report (http://www.reuters.com/article/2011…). That same article revealed that recent radiation readings at Fukushima show “contamination 100,000 times normal in water at reactor No. 2 and 1,850 times normal in the nearby sea.”

Massachusetts rainwater has also been found to be contaminated with low levels of radiation from Fukushima, indicating just how widespread the radioactive fallout has become. It’s not just the West Coast of North America that’s vulnerable, in other words: even the East Coast could receive dangerous levels of fallout if Fukushima suffers a larger release of radioactive material into the air.

Rolling blackouts are now continuing throughout Japan due to the drop in power production from Fukushima diminishing Japan’s electricity generating capacity (http://english.kyodonews.jp/news/20…). The only reason Japan isn’t experiencing widespread power blackouts right now is because so many factories were damaged or swept away from the tsunami itself. Once a serious rebuilding effort gets underway, Japan is going to find itself critically short of electrical power.

The radiation leaking from Reactor No. 2 is now measured at 1,000 millisieverts an hour— more than enough to cause someone’s hair to fall out from a single exposure event. Radiation sickness can begin at just 100 millisieverts. The extremely high levels of radiation are, in fact, making it nearly impossible for workers to continue working at the reactor. “You’d have a lot of difficulty putting anyone in there,” said Richard Wakeford, a radiation epidemiology expert at the Dalton Nuclear Institute in Manchester. “They’re finding quite high levels of radiation fields, which is impeding their progress dealing with the situation.” (http://www.businessweek.com/news/20…)

Taiwan Looking To Ditch Nuclear power?

The worsening Fukushima situation is also starting to spook nearby nations such as Taiwan, which also depends on nuclear power. The DPP opposition party there announced today that it wanted to see nuclear power phased out by 2025. Taiwan is a relatively small island nation, and a Fukushima-like catastrophe would leave most of the island residents with nowhere to go. And like Japan, Taiwan is also vulnerable to earthquakes and tsunamis (as well as hurricanes).

In Germany, massive demonstrations (200,000 people in four large cities) have brought the nuclear safety issue to the forefront, contributing heavily to the defeat of Merkel and the rise to power of the Green Party in southwestern Germany (http://www.nytimes.com/2011/03/28/w…). Germans tend to have very strong opposition to nuclear power, in much the same way that most Europeans despise genetically modified foods.

The Nuclear Power industry Turns Out To Be Just As Corrupt As Big Pharma

The truth is that many nations are rethinking nuclear power right now, thanks to the corruption, cover-ups and outright deceptions that we’re now finding out were behind the Fukushima power plant catastrophe. The nuclear industry, it turns out, is one big profit incest fest where the regulators are deeply in bed with the very industry they’re supposed to regulate (http://online.wsj.com/article/SB100…).

Then again, what rich, powerful industry isn’t in bed with its regulators? It’s true with Big Pharma and the FDA just as much as it is with the nuclear power industry and its corrupt regulators.Every government-run regulator eventually becomes a marketing extension of the industry it was supposed to regulate.

That’s why Big Government never really works: Most of the regulators who are supposed to protect the people inevitably end up operating as industry whores. This entire Fukushima incident is a direct result of that deep-rooted corruption coming back to haunt humanity.
