Japan pictures likely show melted Fukushima fuel for first time — Bloomberg

” New images show what is likely to be melted nuclear fuel hanging from inside one of Japan’s wrecked Fukushima reactors, a potential milestone in the cleanup of one of the worst atomic disasters in history.

Tokyo Electric Power Co. Holdings Inc., Japan’s biggest utility, released images on Friday showing a hardened black, grey and orange substance that dripped from the bottom of the No. 3 reactor pressure vessel at Fukushima, which is likely to contain melted fuel, according to Takahiro Kimoto, an official at the company. The company sent a Toshiba-designed robot, which can swim and resembles a submarine, to explore the inside of the reactor for the first time on July 19.

“Never before have we taken such clear pictures of what could be melted fuel,” Kimoto said at a press briefing that began at 9 p.m. Friday in Tokyo, noting that it would take time to analyze and confirm whether it is actually fuel. “We believe that the fuel melted and mixed with the metal directly underneath it. And it is highly likely that we have filmed that on Friday.”

If confirmed, the substance — which has the appearance of icicles — would be the first discovery of the fuel that melted during the triple reactor accident at Fukushima six years ago. For Tokyo Electric, which bears most of the clean-up costs, the discovery would help the utility design a way to remove the highly-radioactive material.

The robot, which is about 30 centimeters (12 inches) long, will search for melted fuel at the bottom of the reactor on Saturday. It is possible that the company will take more pictures of what could be melted fuel spread across the floor and lower levels, according to Tokyo Electric’s Kimoto. Fuel from a nuclear meltdown is known as corium, which is a mixture of the atomic fuel rods and other structural materials.

Early Signs

“It is important to know the exact locations and the physical, chemical, radiological forms of the corium to develop the necessary engineering defueling plans for the safe removal of the radioactive materials,” said Lake Barrett, a former official at the U.S. Nuclear Regulatory Commission who was involved with the cleanup at the Three Mile Island nuclear power plant in the U.S. “The recent investigation results are significant early signs of progress on the long road ahead.”

Because of the high radioactivity levels inside the reactor, only specially designed robots can probe the unit. And the unprecedented nature of the Fukushima disaster means that Tepco, as the utility is known, is pinning its efforts on technology not yet invented to get the melted fuel out of the reactors.

Removal Plans

The company aims to decide on the procedure to remove the melted fuel from each unit as soon as this summer. And it will confirm the procedure for the first reactor during the fiscal year ending March 2019, with fuel removal slated to begin in 2021.

Decommissioning the reactors will cost 8 trillion yen ($72 billion), according to an estimate in December from the Ministry of Economy, Trade and Industry. Removing the fuel is one of the most important steps in a cleanup that may take as long as 40 years.

Similar to the latest findings on Friday, Tepco took photographs in January of what appeared to be black residue covering a grate under the Fukushima Dai-Ichi No. 2 reactor, which was speculated to have been melted fuel. However, a follow-up survey by another Toshiba-designed robot in February failed to confirm the location of any melted fuel in the reactor after it got stuck in debris.

A robot designed by Hitachi-GE Nuclear Energy Ltd. also failed to find any melted fuel during its probe of the No. 1 reactor in March.

The significance of Friday’s finding “might be evidence that the robots used by Tepco can now deal with the higher radiation levels, at least for periods of time that allow them to search parts of the reactor that are more likely to contain fuel debris,” M.V. Ramana, professor at the Liu Institute for Global Issues at the University of British Columbia, said by email.

“If some of these fragments can be brought out of the reactor and studied, it would allow nuclear engineers and scientists to better model what happened during the accident.” ”

The Fukushima nuclear meltdown continues unabated — Helen Caldicott, Independent Australia

Helen Caldicott sums up the situation here:

” Recent reporting of a huge radiation measurement at Unit 2 in the Fukushima Daichi reactor complex does not signify that there is a peak in radiation in the reactor building.

All that it indicates is that, for the first time, the Japanese have been able to measure the intense radiation given off by the molten fuel, as each previous attempt has led to failure because the radiation is so intense the robotic parts were functionally destroyed.

The radiation measurement was 530 sieverts, or 53,000 rems (Roentgen Equivalent for Man). The dose at which half an exposed population would die is 250 to 500 rems, so this is a massive measurement. It is quite likely had the robot been able to penetrate deeper into the inner cavern containing the molten corium, the measurement would have been much greater.

These facts illustrate why it will be almost impossible to “decommission” units 1, 2 and 3 as no human could ever be exposed to such extreme radiation. This fact means that Fukushima Daichi will remain a diabolical blot upon Japan and the world for the rest of time, sitting as it does on active earthquake zones.

What the photos taken by the robot did reveal was that some of the structural supports of Unit 2 have been damaged. It is also true that all four buildings were structurally damaged by the original earthquake some five years ago and by the subsequent hydrogen explosions so, should there be an earthquake greater than seven on the Richter scale, it is very possible that one or more of these structures could collapse, leading to a massive release of radiation as the building fell on the molten core beneath. But units 1, 2 and 3 also contain cooling pools with very radioactive fuel rods — numbering 392 in Unit 1, 615 in Unit 2, and 566 in Unit 3; if an earthquake were to breach a pool, the gamma rays would be so intense that the site would have to be permanently evacuated. The fuel from Unit 4 and its cooling pool has been removed.

But there is more to fear.

The reactor complex was built adjacent to a mountain range and millions of gallons of water emanate from the mountains daily beneath the reactor complex, causing some of the earth below the reactor buildings to partially liquefy. As the water flows beneath the damaged reactors, it immerses the three molten cores and becomes extremely radioactive as it continues its journey into the adjacent Pacific Ocean.

Every day since the accident began, 300 to 400 tons of water has poured into the Pacific where numerous isotopes – including cesium 137, 134, strontium 90, tritium, plutonium, americium and up to 100 more – enter the ocean and bio-concentrate by orders of magnitude at each step of the food chain — algae, crustaceans, little fish, big fish then us.

Fish swim thousands of miles and tuna, salmon and other species found on the American west coast now contain some of these radioactive elements, which are tasteless, odourless and invisible. Entering the human body by ingestion they concentrate in various organs, irradiating adjacent cells for many years. The cancer cycle is initiated by a single mutation in a single regulatory gene in a single cell and the incubation time for cancer is any time from 2 to 90 years. And no cancer defines its origin.

We could be catching radioactive fish in Australia or the fish that are imported could contain radioactive isotopes, but unless they are consistently tested we will never know.

As well as the mountain water reaching the Pacific Ocean, since the accident, TEPCO has daily pumped over 300 tons of sea water into the damaged reactors to keep them cool. It becomes intensely radioactive and is pumped out again and stored in over 1,200 huge storage tanks scattered over the Daichi site. These tanks could not withstand a large earthquake and could rupture releasing their contents into the ocean.

But even if that does not happen, TEPCO is rapidly running out of storage space and is trying to convince the local fishermen that it would be okay to empty the tanks into the sea. The Bremsstrahlung radiation like x-rays given off by these tanks is quite high – measuring 10 milirems – presenting a danger to the workers. There are over 4,000 workers on site each day, many recruited by the Yakuza (the Japanese Mafia) and include men who are homeless, drug addicts and those who are mentally unstable.

There’s another problem. Because the molten cores are continuously generating hydrogen, which is explosive, TEPCO has been pumping nitrogen into the reactors to dilute the hydrogen dangers.

Vast areas of Japan are now contaminated, including some areas of Tokyo, which are so radioactive that roadside soil measuring 7,000 becquerels (bc) per kilo would qualify to be buried in a radioactive waste facility in the U.S..

As previously explained, these radioactive elements concentrate in the food chain. The Fukushima Prefecture has always been a food bowl for Japan and, although much of the rice, vegetables and fruit now grown here is radioactive, there is a big push to sell this food both in the Japanese market and overseas. Taiwan has banned the sale of Japanese food, but Australia and the U.S. have not.

Prime Minister Abe recently passed a law that any reporter who told the truth about the situation could be [jail]ed for ten years. In addition, doctors who tell their patients their disease could be radiation related will not be paid, so there is an immense cover-up in Japan as well as the global media.

The Prefectural Oversite Committee for Fukushima Health is only looking at thyroid cancer among the population and by June 2016, 172 people who were under the age of 18 at the time of the accident have developed, or have suspected, thyroid cancer; the normal incidence in this population is 1 to 2 per million.

However, other cancers and leukemia that are caused by radiation are not being routinely documented, nor are congenital malformations, which were, and are, still rife among the exposed Chernobyl population.

Bottom line, these reactors will never be cleaned up nor decommissioned because such a task is not humanly possible. Hence, they will continue to pour water into the Pacific for the rest of time and threaten Japan and the northern hemisphere with massive releases of radiation should there be another large earthquake. ”

Fukushima cover up — CounterPunch

” It is literally impossible for the world community to get a clear understanding of, and truth about, the Fukushima nuclear disaster. This statement is based upon The Feature article in Columbia Journalism Review (“CJR”) d/d October 25, 2016 entitled: “Sinking a Bold Foray Into Watchdog Journalism in Japan” by Martin Fackler.

The scandalous subject matter of the article is frightening to its core. Essentially, it paints a picture of upending and abolishing a 3-year attempt by one of Japan’s oldest and most liberal/intellectual newspapers, The Asahi Shimbun (circ. 6.6 mln) in its effort of “watchdog journalism” of the Fukushima nuclear disaster. In the end, the newspaper’s special watchdog division suffered un-preannounced abrupt closure.

The CJR article, whether intentionally or not, is an indictment of right wing political control of media throughout the world. The story is, moreover, extraordinarily scary and of deepest concern because no sources can be counted on for accurate, truthful reporting of an incident as powerful and deadly dangerous as the nuclear meltdown at Fukushima. Lest anybody in class forgets, three nuclear reactors at Fukushima Diiachi Nuclear Power Plant experienced 100% meltdown, aka The China Syndrome over five years ago.

The molten cores of those reactors melted down to a stage called corium, which is a lumpy hunk of irradiating radionuclides so deadly that robotic cameras are zapped! The radioactivity is powerful, deadly and possessed of frightening longevity, 100s of years. Again for those who missed class, TEPCO (Tokyo Electric Power Company) has no idea where those masses of sizzling hot radioactive goo are today. Did they burrow into the ground? Nobody knows, but it is known that those blobs of radioactivity are extraordinarily dangerous, as in deathly, erratically spewing radioactivity “who knows where”?

Fukushima is a national/worldwide emergency that is the worst kept secret ever because everybody knows it is happening; it is current; it is alive; it is deadly; it has killed (as explained in several prior articles) and will kill many more as well as maim countless people over many decades (a description of radiation’s gruesomeness follows later on in this article).

Yet, the Abe administration is talking to Olympic officials about conducting Olympic events, like baseball, in Fukushima for Tokyo 2020. Are they nuts, going off the deep end, gone mad, out of control? After all, TEPCO readily admits (1) the Fukushima cleanup will take decades to complete, if ever completed, and (2) nobody knows the whereabouts of the worlds most deadly radioactive blobs of sizzling hot masses of death and destruction, begging the question: Why is there a Chernobyl Exclusion Zone of 1,000 square miles after one nuclear meltdown 30 years ago, but yet Fukushima, with three meltdowns, each more severe than Chernobyl, is already being repopulated? It doesn’t compute!

The short answer is the Abe administration claims the radioactivity is being cleaned up. A much longer answer eschews the Abe administration by explaining the near impossibility of cleaning up radioactivity throughout the countryside. There are, after all, independent organizations with boots on the ground in Fukushima (documented in prior articles) that tell the truth, having measured dangerous levels of radiation throughout the region where clean up crews supposedly cleaned up.

The Columbia Journalism Review article, intentionally or not, paints a picture of “journalism by government decree” in Japan, which gainsays any kind of real journalism. It’s faux journalism, kinda like reading The Daily Disneyworld Journal & Times.

Based upon the CJR article: “The hastiness of the Asahi’s retreat raised fresh doubts about whether such watchdog journalism— an inherently risky enterprise that seeks to expose and debunk, and challenge the powerful—is even possible in Japan’s big national media, which are deeply tied to the nation’s political establishment.”

Japan’s journalists belong to “press clubs,” which are exclusively restricted to the big boys (and girls) from major media outlets, where stories are hand-fed according to government officialdom, period. It is the news, period! No questions asked, and this is how Asahi got into trouble. They set up a unit of 30-journalists to tell the truth about Fukushima and along the way won awards for journalism, until it suddenly, abruptly stopped. A big mystery ensues….

According to the CJR article, “The Investigative Reporting Section [Asahi] proved an instant success, winning Japan’s top journalism award two years in a row for its exposure of official cover-ups and shoddy decontamination work around the nuclear plant.”

Furthermore, according to the CJR article: “The abrupt about-face by the Asahi, a 137-year-old newspaper with 2,400 journalists that has been postwar Japan’s liberal media flagship, was an early victory for the administration of Prime Minister Shinzo Abe, which had sought to silence critical voices as it moved to roll back Japan’s postwar pacifism, and restart its nuclear industry.”

And, furthermore, the truth be told: “In Japanese journalism, scoops usually just mean learning from the ministry officials today what they intend to do tomorrow,’ says Makoto Watanabe, a former reporter in the section who quit the Asahi in March because he felt blocked from doing investigative reporting. ‘We came up with different scoops that were unwelcome in the Prime Minister’s Office.”

It comes as no surprise that Reporters Without Borders lowered Japan’s rating from 11th in 2010 (but one has to wonder how they ever got that high) to 72nd in this years annual ranking of global press freedoms, released on April 20, 2016.

Koichi Nakano, a professor of politics at Sophia University in Tokyo, says: “Emasculating the Asahi allowed Abe to impose a grim new conformity on the media world.”

When considering the awards Asahi won during its short foray into investigative journalism, like Japan’s equivalent of the Pulitzer Prize in 2012 for reporting about a gag-order on scientists after the Fukushima disaster and the government’s failure to release information about radiation to evacuating residents, now that Asahi has been forced to put a lid on “investigative journalism” and it must toe the line in “press clubs,” any and all information about the dangers or status of Fukushima are ipso facto suspect!

The world is dead silent on credible information about the world’s biggest disaster! (Which causes one to stop and think… really a lot.)

The evidence is abundantly clear that there is no trustworthy source of information about the world’s biggest nuclear disaster, and likely one of the biggest dangers to the planet in human history. However, time will tell as radiation exposure takes years to show up in the human body. It’s a silent killer but cumulates over time. Fukushima radiation goes on and on, but nobody knows what to do. To say the situation is scandalous is such a gross understatement that it is difficult to take it as seriously as it really should be taken. But, it is scandalous, not just in Japan but for the entire planet.

After all, consider this, 30 years after the fact, horribly deformed Chernobyl children are found in over 300 asylums in the Belarus backwoods deep in the countryside. Equally as bad but maybe more odious, as of today, Chernobyl radiation (since 1986) is already affecting 2nd generation kids.

According to USA Today, Chernobyl’s Legacy: Kids With Bodies Ravaged by Disaster, April 17, 2016: “There are 2,397,863 people registered with Ukraine’s health ministry to receive ongoing Chernobyl-related health care. Of these, 453,391 are children — none born at the time of the accident. Their parents were children in 1986. These children have a range of illnesses: respiratory, digestive, musculoskeletal, eye diseases, blood diseases, cancer, congenital malformations, genetic abnormalities, trauma.”

It’s taken 30 years for the world, via an article in USA Today, to begin to understand how devastating, over decades, not over a few years, radiation exposure is to people. It is a silent killer that cumulates in the body over time and passes from generation to generation to generation, endless destruction that cannot be stopped! ”

What are the consequences of three corium ‘melt-outs’ at Fukushima No. 1, and why is the world ignoring this? — AGreenRoad Project seeks the answers

The nuclear cores of Fukushima Daiichi’s Units 1 through 3 have not only melted down, but significant evidence and expert consensus show that corium (or lava-like fuel containing material from a reactor core) from each reactor melted OUT of its containment into the ground. Where exactly is it, and what risks does this situation pose for the decommissioning process and further contamination of the Pacific Ocean? So far, Tokyo Electric does not know where the reactors’ corium is nor has it expressed any concern or initiative to find out! Fact: concrete cannot contain melted nuclear fuel, and therefore, it is quite likely if not obvious that the corium has melted its way through the concrete and earth beneath the reactors.

AGreenRoad Project provides many article references that evidence the melted out corium at Units 1 through 3 and discusses the possible consequences and lack of concern and initiative from Tepco, the Japanese government and the international community. This article also examines the constitution of corium and the reactions possible in difference scenarios, in addition to the corium reactions that occurred at the Chernobyl and Three Mile Island meltdowns.
