Fukushima nuclear wasteland revealed as residents slowly dare to return to devastated ghost towns — The Sun

” Eight years after fleeing their homes after a tsunami caused Fukushima’s nuclear power plant to go into meltdown, just a tiny trickle have braved returning to the evacuation zone.

Local officials paint a rosy picture, but few of the 100,000 evacuees have reclaimed their homes, offices, schools and streets from weaving weeds and roaming wild boars.

Three reactors went into meltdown after the 2011 Japanese tsunami sparked the worst nuclear accident since the 1986 Chernobyl catastrophe.

Radiation leaks left an apocalyptic vision of ghost towns and overgrown wildernesses, and scared residents refusing to go home.

Nevertheless, the Japanese government is keen for evacuees to return as soon, as it claims, is safe to do so.

In fact, it is so desperate to recover quickly from the disaster it has ploughed at least £21billion into the epic clean up.

A huge army of more than 70,000 workers have scooped away topsoil, removed tree branches and dug up grass in areas near homes, schools and public buildings in a bid to decontaminate.

Millions upon millions of cubic metres of radioactive soil has been poured into bags. They are then removed and safely stored.

All the while in a town nearby a Saga arcade slowly fades, with dust blanketing everything, while elsewhere vegetation creeps and crawls into nooks and crannies, floors and doors.

Some places on the other hand look eerily unaffected, frozen in time.

There are streets and offices perfectly preserved — as if one day humanity suddenly vanished.

Progress IS being made in the clean-up, however.

This month radiation levels in parts of the town Okuma, west of the crippled nuclear plant, have been deemed safe for its residents to return home.

The Japanese Prime Minister, Shinzo Abe, visited to mark the milestone.

Yet according to local reports just 367 residents of Okuma’s original population of 10,341 have so far said they are going to return home.

Parts of the town remains off-limits until about 2022.

Despite all this the mayor of Okuma was upbeat when speaking to Japanese reporters.

He said: “It has taken many years to get to where we are now, but I am happy that we made it.”

CAMPAIGN TO CONVINCE EVACUEES TO RETURN

This comes amid a big push to persuade people to go home and pick up where they left off.

But many residents have voted with their feet — that is to say they’ve stayed away.

They and campaigners, along nuclear experts across the globe, believe it is just not safe.

Japanese authorities are accused of wanting to allay public fears over nuclear power by downplaying the dire consequences of the leak.

Some critics have also accused the Japanese government of talking up residents’ return as part of a public relations exercise ahead of the 2020 Tokyo Olympics.

But despite the bad publicity a nuclear disaster on this scale has obviously brought, officials say new figures show the largest year-on-year growth in foreign visitors to Fukushima.

The Japanese Times is now reporting tourism was up roughly 2.4 times from the same month the previous year.

This comes after the number foreign lodgers in the region reached 120,250 last year which breached 100,000 line since the nuclear crisis.

A Fukushima prefecture spokesman said: “We hope to utilize every possible means to promote the prefecture’s attractiveness as a tourist destination to bring in more visitors.”

Eight years on, water woes threaten Fukushima cleanup — Reuters

” OKUMA, Japan (Reuters) – Eight years after the Fukushima nuclear crisis, a fresh obstacle threatens to undermine the massive clean-up: 1 million tons of contaminated water must be stored, possibly for years, at the power plant.

Last year, Tokyo Electric Power Co said a system meant to purify contaminated water had failed to remove dangerous radioactive contaminants.

That means most of that water – stored in 1,000 tanks around the plant – will need to be reprocessed before it is released into the ocean, the most likely scenario for disposal.

Reprocessing could take nearly two years and divert personnel and energy from dismantling the tsunami-wrecked reactors, a project that will take up to 40 years.

It is unclear how much that would delay decommissioning. But any delay could be pricey; the government estimated in 2016 that the total cost of plant dismantling, decontamination of affected areas, and compensation, would amount to 21.5 trillion yen ($192.5 billion), roughly 20 percent of the country’s annual budget.

Tepco is already running out of space to store treated water. And should another big quake strike, experts say tanks could crack, unleashing tainted liquid and washing highly radioactive debris into the ocean.

Fishermen struggling to win back the confidence of consumers are vehemently opposed to releasing reprocessed water – deemed largely harmless by Japan’s nuclear watchdog, the Nuclear Regulation Authority (NRA) – into the ocean.

“That would destroy what we’ve been building over the past eight years,” said Tetsu Nozaki, head of the Fukushima Prefectural Federation of Fisheries Co-operative Associations. Last year’s catch was just 15 percent of pre-crisis levels, partly because of consumer reluctance to eat fish caught off Fukushima.

SLOW PROGRESS

On a visit to the wrecked Fukushima Dai-ichi plant last month, huge cranes hovered over the four reactor buildings that hug the coast. Workers could be seen atop the No. 3 building getting equipment ready to lift spent fuel rods out of a storage pool, a process that could start next month.

In most areas around the plant, workers no longer need to wear face masks and full body suits to protect against radiation. Only the reactor buildings or other restricted areas require special equipment.

Fanning out across the plant’s property are enough tanks to fill 400 Olympic-sized swimming pools. Machines called Advanced Liquid Processing Systems, or ALPS, had treated the water inside them.

Tepco said the equipment could remove all radionuclides except tritium, a relatively harmless hydrogen isotope that is hard to separate from water. Tritium-laced water is released into the environment at nuclear sites around the world.

But after newspaper reports last year questioned the effectiveness of ALPS-processed water, Tepco acknowledged that strontium-90 and other radioactive elements remained in many of the tanks.

Tepco said the problems occurred because absorbent materials in the equipment had not been changed frequently enough.

The utility has promised to re-purify the water if the government decides that releasing it into the ocean is the best solution. It is the cheapest of five options a government task force considered in 2016; others included evaporation and burial.

Tepco and the government are now waiting for another panel of experts to issue recommendations. The head of the panel declined an interview request. No deadline has been set.

NRA chief Toyoshi Fuketa believes ocean release after dilution is the only feasible way to handle the water problem. He has warned that postponing the decision indefinitely could derail the decommissioning project.

STORING INDEFINITELY

Another option is to store the water for decades in enormous tanks normally used for crude oil. The tanks have been tested for durability, said Yasuro Kawai, a plant engineer and a member of Citizens’ Commission on Nuclear Energy, a group advocating abandoning nuclear energy.

Each tank holds 100,000 tons, so 10 such tanks could store the roughly 1 million tons of water processed by ALPS so far, he said.

The commission proposes holding the tritium-laced water, which has a half life of 12.3 years, in tanks for 123 years. After that, it will be one thousandth as radioactive as it was when it went into storage.

Although experts caution that tanks would be vulnerable to major quakes, Japan’s trade and industry minister, Hiroshige Seko, said the committee would consider them anyway.

“Long-term storage … has an upside as radiation levels come down while it is in storage. But there is a risk of leakage,” Seko told Reuters. “It is difficult to hold the water indefinitely, so the panel will also look into how it should be disposed of eventually.”

Space is also a problem, said Akira Ono, Tepco’s chief decommissioning officer. By 2020, the utility will expand tank storage capacity by 10 percent to 1.37 million tons, and about 95 percent of total capacity will probably be used by the end of that year, he said.

“Tanks are now being built on flat, elevated spots in stable locations,” Ono said. But such ideal space is getting scarce, he added.

Many local residents hope Tepco will just keep storing the water. If it does get released into the ocean, “everyone would sink into depression,” said fishing trawler captain Koichi Matsumoto.

Fukushima was once popular with surfers. But young people in the area do not go surfing any more because they’ve been repeatedly warned about suspected radioactivity in the water, said surf shop owner Yuichiro Kobayashi.

Releasing treated water from the plant “could end up chasing the next generation of children away from the sea as well,” he said.

Ono says dealing with contaminated water is one of many complex issues involved in decommissioning.

A year ago, when he took over leading the effort, it felt like the project had just “entered the trailhead,” he said. “Now, it feels like we’re really starting to climb.” ”

Fukushima’s underground ice wall keeps nuclear radiation at bay — CNET

” The intricate network of small metal pipes, capped off by six-foot-high metal scaffolding, shouldn’t stand out amid the numerous pieces of industrial equipment littered throughout the Fukushima Daiichi Nuclear Power Plant. After all, it’s a power plant.

I take a closer look, and notice spheres of ice perched upon the smaller pipes, which line the center of the structure. The facility sits at the water’s edge, and there’s a brisk breeze blowing through.

But not that brisk.

It turns out, coolant is running through the pipes, freezing the soil below and creating an impermeable ice wall that’s nearly 100 feet deep and a mile long, encircling the reactors.

It’s like a smaller-scale subterranean version of the Wall in Game of Thrones, but instead of keeping out White Walkers and wights, this line of defense keeps in a far more realistic danger: radioactive contaminants from melted-down reactors that threaten to spill into the water by Fukushima Daiichi.

Daiichi is the site of the worst nuclear disaster, which happened after an earthquake hit on March 11, 2011, triggering a tsunami that devastated the facility. Two 50-foot-high waves knocked out the power generators that were keeping three of the six reactors’ fuel rods cool, triggering explosions and meltdowns that forced more than 160,000 people to flee their homes. Many of them still haven’t returned.

I came to Fukushima to check out the robots tasked with the near-impossible task of cleaning up Fukushima Daiichi. While here, I encountered this underground wall of ice.

The structure, which cost roughly $300 million, paid for by public funds, serves as critical protection, defending the Fukushima area from one of the most radioactive hotspots in the world. While Tokyo Electric Power Co., also known as Tepco, struggles to find a way to remove radioactive material from the facility – a process the government estimates could take more than four decades – the more immediate concern is what to do with the contaminated water leaking out from the facility.

One of the solutions has been to put up (down?) this underground ice wall, which prevents much of the surrounding groundwater from getting in. And while the practice of freezing soil to create a barrier has been around for more than 150 years, the magnitude of the application that stands before me is quite literally groundbreaking.

“Nobody has taken on a project of this scale,” Hideki Yagi, general manager of Tepco’s Nuclear Power Communications Unit, tells me through an interpreter.

Ice cold

While the term “ice wall” has a colorful ring to it, engineers use the more academic-sounding term Artificial Ground Freezing. The technique came out of France in 1862 as a way to help with the construction of mine shafts before German engineer F.H. Poetsch patented it. Since then, it’s been used to aid in building underwater tunnels or vertical shafts, as well as to cut off groundwater or redirect contaminated materials.

At Fukushima, my eyes follow the path of the pipes, which stretch around the reactor building. A Tepco employee tells me that a calcium chloride solution is pumped down through a smaller inner pipe, and circulated back up a large outer pipe.

The coolant brings down the temperature of each pipe to -30 degrees Celsius, or -22 degrees Fahrenheit, and the pipes are spaced about three feet apart. The cold emanating from each one hardens the soil around it.

The point of the ice wall is to keep the groundwater that runs down from the mountains to the west from entering Fukushima Daiichi and mixing with the toxic water leaking out of the Unit 1, 2 and 3 reactors. That is,  keep the clean water on the outside of the wall, while the contaminated water stays inside.

Tepco and manufacturing partners, such as Toshiba and Mitsubishi, are working on robots to identify and determine how to clear out the radioactive materials in each of the reactors’ primary containment vessels, essentially the heart of each facility.

Until then, they need a way to slow or stop the flow of water into the facility. At least initially, Tepco wasn’t even sure if the project was feasible.

“One of the challenges was how they would inject the pipes into the earth at such a deep level without impacting the other operations around it, and whether it would work,” Yagi says.

With the wall in place, Tepco says it has been able to reduce the level of contaminated water generated from Daiichi. But a Reuters report in March 2018 found that the wall still let a fair amount of clean water in, adding to the volume of toxic water the company needs to deal with. Tepco, however, says it’s been effective in reducing the volume.

“We know this is not the end of our effort,” says a company spokesman. “We will be continuously working hard to reduce the amount of  generation of contaminated water.”

The leaky bucket

Imagine a leaky bucket that constantly needs to be filled with water. At the same time, the water from the leak needs to be collected and stored. And there’s no end in sight to this cycle.

That essentially is the problem that Tepco faces at Daiichi. The fuel rods stored in the three radioactive units constantly have to be cooled with fresh water, but leaks mean the company needs to be vigilant about keeping the tainted liquid from getting out of the facility’s grounds.

Since the accident nearly eight years ago, Tepco has collected 1.1 million tons of contaminated water in 900 tanks stored on the grounds at Daiichi. The company estimates it has enough space in the 37.7-million-square-foot facility to house an additional 270,000 tons of water, which means it would run out sometime in 2020.

“We’re conscious of the fact that we can’t keep storing more and more water,” Kenji Abe, a spokesman for Tepco’s decommissioning and decontamination unit, says through an interpreter.

Tepco has worked on several solutions to decrease the level of contaminated water generated by the facility. The company has switched from tanks sealed with bolts to welded tanks, which offer greater storage capacity and less risk of leaks. There’s a steel wall by the water to keep the contaminants from flowing into the ocean. Tepco has also covered 96 percent of the surface of most of the facility with concrete, preventing rainwater from seeping in.

Then there’s the ice wall, which has done its share of lowering the amount of contaminated water generated from the facility by keeping out most of the groundwater.

Over the past three and a half years, Tepco has seen the amount of polluted water generated fall by a quarter to just under 3,900 cubic feet of water per day, with occasional spikes during periods of rainfall.

The final element

I’m in full protective gear, including a Tyvek coverall, hardhat and full-face respirator mask, walking through one of three water treatment facilities at Daiichi. I move hastily, trying to keep up with my Tepco guides, when my suit gets snagged on an exposed bolt.

Did the suit rip? My eyes shoot back at my photographer and widen with fear. This is usually the part in an outbreak movie that dooms a key character. I look down and see the suit is still intact, and breathe a sigh of relief.

It turns out, I didn’t need to panic. The facility, called the Advanced Liquid Processing System, isn’t radioactive, although it’s designed to remove radioactive elements from the collected water. There are three such facilities, which can process a total of 70,630 cubic feet of water a day.

So far, treatment technology from partner companies like Kurion and Sarry have enabled Tepco to remove 62 of the 63 radioactive elements from the water, but one, tritium, remains.

It’s this one element, which is bonded to the water at an atomic level, that means Tepco needs to keep collecting and storing the water.

Lake Barrett, a senior adviser to Tepco who previously served as acting director of the Office of Civilian Radioactive Waste Management at the US Department of Energy, notes that reactors in China and Canada already discharge water with tritium.

“It’s fundamentally safe,” Barrett says.

But organizations such as Greenpeace have called for Tepco to keep storing the water, noting that much of the early batches of treated water far exceed safety limits for radioactive elements.

Given the sensitivities around Fukushima, Tepco must continue to store the water. A spokesman said the company isn’t planning to disperse the water. But it is one option being considered by the Japanese government, which ultimately makes the decision.

“Resolving the issue of the contaminated water is something we haven’t yet reached a final solution on,” Yagi says.

Analyzing the data

Underneath the building housing the restaurant and employee rest area is a water treatment analysis center, a super-clean area that requires us to go through numerous radiation tests and four sets of boot changes.

There are glass beakers containing sea water, groundwater and water from the ALPS facilities. Scientists walk around in silence, moving beakers from one machine to another. A dozen machines in a second room measure the gamma ray levels.

The facility was originally built underground in 2014 because it needed to be on the Daiichi site, but couldn’t be exposed to radiation because of the nature of the tests. The walls are 8 inches thick, with the more sensitive labs hardened with an additional 20 inches. The facility has grown by 16 times over the past four years as it expanded the number of workers and machines.

“No other facility in Japan can handle the amount of data and work we do here,” says a Tepco scientist working at the facility who preferred not to identify himself.

He adds that all of the data is released publicly. “That’s because society demands work with a high level of trust,” he says.

The scientist explains that Japan has set a legal radioactivity limit of 60,000 becquerel per liter of tritium. But the treated water is still at 1.7 million Bq per liter, or roughly 30 times what’s deemed safe.

So, for now, Tepco must continue collecting the water. And the ice wall continues to stand, invisible to onlookers, as one of the most important lines of defense. ”

Prime Minister Abe uses the Tokyo Olympics as snake oil cure for the Fukushima Daiichi nuclear meltdowns — Fairewinds Energy Education

” As we prepare for the eighth remembrance of the March 11, 2011 earthquake, tsunami and triple meltdowns at Fukushima Daiichi, Fairewinds is ever mindful of what is currently happening in Japan.

There has never been a roadmap for Japan to extricate itself from the radioactive multi-headed serpentine Hydra curse that has been created in an underfunded, unsuccessful attempt to clean-up the ongoing spread of migrating radioactivity from Fukushima. Rather than focus its attention on mitigating the radioactive exposure to Japan’s civilians, the government of Japan has sought instead to redirect world attention to the 2020 Olympics scheduled to take place in Tokyo.

Truthfully, a situation as overwhelming as Fukushima can exist in every location in the world that uses nuclear power to produce electricity. The triple meltdowns at Fukushima Daiichi are the worst industrial catastrophe that humankind has ever created.

Prior to Fukushima, the atomic power industry never envisioned a disaster of this magnitude anywhere in the world. Worldwide, the proponents and operators of nuclear power plants still are not taking adequate steps to protect against disasters of the magnitude of Fukushima!

Parts of Japan are being permanently destroyed by the migrating radioactivity that has been ignored, not removed, and subsequent ocean and land contamination is expanding and destroying once pristine farmlands and villages. For reference in the US and other countries, Fukushima Prefecture is approximately the size of the State of Connecticut. Think about it, how would an entire State – its woods, rivers, and valleys, eradicate radioactive contamination?

Let’s begin with the reactors and site itself. There was a triple meltdown in 2011, yet Tokyo Electric banned the use of the word “meltdown” in any of its communications with Japanese civilians. Now we know that in the first week after the tsunami, each molten radioactive core melted through its six-inch-thick steel reactor, burned and chemically reacted with the concrete underneath, and all are now lying in direct contact with groundwater. Aside from a few grainy pictures of those cores showing burn holes in the reactors, nothing has been done to remove the cores and to prevent further contamination of the groundwater. I have witnessed schemes including a mining operation to bore under the reactors and an underground train to collect the molten masses, but those schemes are decades from fruition. The government of Japan claims that the Fukushima site will be entirely cleaned and decommissioned in less than forty years, a date that will definitely slip AFTER the 2020 Tokyo Olympics are held, and one that is scientifically impossible since some radioactive isotopes will be spread across the Fukushima site and surrounding landscape for 300 years and others for 250,000 years.

Fukushima’s radioactive reactor cores have been in direct contact with groundwater for the last eight years, and then that highly toxic radioactive water enters the Pacific Ocean. When the disaster struck TEPCO wanted to build an ice-wall to prevent the spread of the contamination, which I knew would fail. I advocated immediately surrounding the reactors with a trench filled with zeolite, a chemical used to absorb radiation at other atomic facilities.

“The problem with freezing the soil is that as soon as you get an earthquake, you lose power and then your ice turns to mush and you’re stuck.” Gundersen, who has visited the Fukushima power plant in the past, said a better solution would be to dig a two-meter wide trench down to bedrock level and fill it with a material called zeolite: a volcanic material that comes from Mother Nature.

“It’s incredibly good at filtering radioactive isotopes. So whatever is inside the fence will stay inside and whatever is outside the fence would be clean,” said Gundersen, who estimates the price tag for such a project would be around $10 billion.

TEPCO’s ice wall has not eliminated radiation from spreading via groundwater. How will Fukushima’s owner TEPCO and the government of Japan successfully clean and mitigate the damage caused by the three atomic reactors that each lost their fuel to a meltdown? These problems were never anticipated in Japan where these reactors were built and operated or in the United States where the Fukushima nuclear plants were engineered and designed and the parts were manufactured.

Since the meltdowns in 2011, Fairewinds notified the world that the recovery plans for the proposed cleanup would be almost untenable, calling it a ‘long slog’. From the very beginning, I made it clear that “the nuclear disaster is underfunded and lacks transparency, causing the public to remain in the dark.” Sadly, eight years later, nothing has changed.

In February 2012 when I spoke to the press at the Tokyo Foreign Correspondents Press Club, the government’s recovery from the radiation released by Fukushima has never been about protecting the people of Japan. It was clear in the immediate aftermath of the world’s largest atomic power disaster and still today, the government of Japan is focused on protecting the financial interests of the nuclear power corporations in Japan so they may build new reactors as well as continue to operate the old ones. Clearly, the steps taken by the government of Japan shows that the survival of the electric generating corporations like Hitachi, Toshiba, Tokyo Electric and others are more important to the Abe Government that the survival of 160,000 evacuees and the future of the food supply emanating from Japan’s agriculture and aquaculture.

Evacuees in Japan are being forced to move back to their community and their homes that remain radioactively contaminated by the Fukushima Daiichi detonations and meltdowns. The government of Japan and the alleged global regulator, the International Atomic Energy Agency (IAEA) – which was chartered by the United Nations (UN) to both promote and regulate atomic power generation – have raised the allowable public radiation level more than 20-times what it originally was rather than return to land to the condition it once was.

An exposé released in early February 2019 in The Washington Post said that, 

For six years, Namie was deemed unsafe after a multiple-reactor meltdown at the Fukushima Daiichi Nuclear Power Plant following a 2011 earthquake and tsunami. In March 2017, the government lifted its evacuation order for the center of Namie. But hardly anyone has ventured back. Its people are scattered and divided. Families are split. The sense of community is coming apart…

As we at Fairewinds Energy Education have repeatedly said since the tragic 2011 meltdowns, understanding why the fate of the 160,000 evacuees from the toxic Fukushima landscape does not matter to the government of Japan, one must simply follow the money trail back to the corporations producing Japan’s electricity. As Fairewinds has noted from its personal experience, and what The Washington Post and the people of Japan clearly understand is that these meltdown refugees are simply pawns in a much bigger issue of money and politics. According to The Washington Post article,

For the people of Namie and other towns near the Fukushima plant, the pain is sharpened by the way the Japanese government is trying to move beyond the tragedy, to use the 2020 Tokyo Olympics as a symbol of hope and recovery, a sign that life can return to normal after a disaster of this magnitude…. Its charm offensive is also tied up with efforts to restart the country’s nuclear-power industry, one of the world’s most extensive networks of atomic power generation. [Emphasis Added].

Six Olympic softball games and a baseball game will be staged in Fukushima, the prefecture’s bustling and radiation-free capital city, and the Olympic torch relay will start from here.

To determine whether or not Olympic athletes might be affected by fallout emanating from the disaster site, Dr. Marco Kaltofen and I were sponsored by Fairewinds Energy Education to look at Olympic venues during the fall of 2017. We took simple dirt and dust samples along the Olympic torch route as well as inside Fukushima’s Olympic stadium and as far away as Tokyo. When the Olympic torch route and Olympic stadium samples were tested, we found samples of dirt in Fukushima’s Olympic Baseball Stadium that were highly radioactive, registering 6,000 Bq/kg of Cesium, which is 3,000 times more radioactive than dirt in the US. We also found that simple parking lot radiation levels were 50-times higher there than here in the US.

Thirty of the dirt and fine dust samples that I took on my last two trips to Japan in February and March 2016 and September 2017 were analyzed at WPI (Worchester Polytechnic Institute. The WPI laboratory analysis are detailed in the report entitled: Measuring Radioactivity in Soil and Dust Samples from Japan, T. Pham, S. Franca and S. Nguyen, Worchester Polytechnic Institute, which found that:

With the upcoming XXXII Olympiad in 2020 hosted by Japan, it is necessary to look into the radioactivity of Olympic venues as well as tourist attractions in the host cities… Since thousands of athletes and millions of visitors are traveling to Japan for the Olympics, there has been widespread concern from the international community about radiation exposure. Therefore, it is important to investigate the extent of radioactive fallout from the Fukushima Dai-ichi incident…

The measured results showed a much higher activity of Cesium-137 in the proposed torch route compared to other areas. Overall, the further away from the Fukushima Dai-ichi Nuclear Power Plant, the lower the radioactivity. The activity of Cesium-137 in Tokyo, the furthest site from the plant, was the lowest when compared to the other sites. Therefore, the activity of Cesium-137 in Tokyo sample was used as the baseline to qualitatively estimate the human exposure to radiation.

.… At the Azuma Sports Park, the soil and dust samples yielded a range of 78.1 Bq/kg to 6176.0 Bq/kg. This particular Olympic venue is around 90 km from the Nuclear Power Plant. The other sites that are closer to the Nuclear Power Plant like the tourist route, proposed torch route, and non-Olympic samples have higher amounts due to the close proximity to ground zero of the disaster.

 … the proposed torch route samples had the highest mean radioactivity due to their close proximity to the plant. Based on the measurement, we estimated qualitatively that the radiation exposure of people living near the Azuma Sports Park area was 20.7 times higher than that of people living in Tokyo. The main tourist and proposed torch routes had radiation exposure of 24.6 and 60.6 times higher, respectively, than in Tokyo…. Olympic officials should consider using the results of this project to decide whether the radioactivity level at the proposed torch route and the Olympic venues are within acceptable level.

On a more personal note, I witnessed first-hand the ongoing radioactive devastation in and around the Namie area like that detailed in The Washington Post’s revealing and factual essay. During the two weeks I spent in and around Namie in September 2017 I took six short videos showing what the devastation looks and feels like up close. These short iPhone videos total less than 5-minutes of run time. I was on my own, without a videographer, so these short films probably lack the professional quality viewers may usually associate with Fairewinds, however, they do convey the very palpable feeling of gloom and emptiness pervading the ghost towns I visited. I am sharing the first three short videos in today’s blog. We will be releasing a Part 2 of this Fukushima update, which will feature another three short films.

Longtime Friends of Fairewinds may remember that back in 2011, Prime Minister Noda (he was between the ousted Prime Minister Naoto Kan, who was PM when the Fukushima Meltdowns occurred and today’s Prime Minister Abe), claimed that the three melted down Fukushima reactors were in ‘cold shutdown’, which they were not, in order to lay the groundwork for Japan’s Olympic bid. Noda claimed “… we can consider the accident contained”. Fairewinds compared Noda’s “cold shutdown” hypocrisy to former President George Bush crowing about “Mission Accomplished” in Iraq. Sadly, what we said in 2011 still rings true today:

Is the Japanese government and the IAEA protecting the nuclear industry and not the people of Japan by claiming that Fukushima is stable when it is not? Fairewinds’ chief engineer Arnie Gundersen outlines major inconsistencies and double-speak by the IAEA, Japanese Government, and TEPCO claiming that the Fukushima accident is over. Dynamic versus static equilibrium, escalated dose exposures to the Japanese children and nuclear workers, and the blending of radioactive materials with non-contaminated material and spreading this contaminated ash throughout Japan are only a small part of this ongoing nuclear tragedy.

Later in 2013, Japan pressed the International Olympic Committee and bribed some of its members to accept the Olympics in 2020 according to an Associated Press article February 18, 2019 by Journalist Haruka Nuga.

Members of the JOC executive board are up for re-election this summer. There is speculation Takeda…[ Japanese Olympic Committee President Tsunekazu Takeda, who is being investigated for his part in an alleged bribery scandal] will not run, or could be replaced. French investigators believe he may have helped Tokyo win the 2020 Olympics in a vote by the International Olympic Committee.

Takeda has been JOC president since 2001. He is also a powerful IOC member and the head of its marketing commission. He has not stepped aside from either position while the IOC’s ethics committee investigates.

…French authorities suspect that about $2 million paid by the Tokyo bid committee — headed by Takeda — to a Singapore consulting company, Black Tidings, found its way to some IOC members in 2013 when Tokyo won the vote over bids from Istanbul and Madrid… Takeda last month acknowledged he signed off on the payments but denied corruption allegations. An internal report in 2016 by the Japanese Olympic Committee essentially cleared Takeda of wrongdoing.

Tokyo is spending at least $20 billion to organize the Olympics. Games costs are difficult to track, but the city of Tokyo appears to be picking up at least half the bill.

Much of Japan’s focus has been to show that the Fukushima area is safe and has recovered from a 2011 earthquake, tsunami, and the meltdowns at three nuclear reactors. [Emphasis Added]

Here is what I said in a video on Fairewinds website in 2013, when the original Tokyo Olympic announcement was made.

I think hosting the Olympics in 2020 is an attempt by the Japanese to change the topic. I don’t think people around the world are going to care until 2020 approaches. There is a seven-year window for the Japanese government to work to make Tokyo a showcase for the entire world to view. I think the Japanese government wanted to host the Olympics to improve the morale of the people of Japan after the Fukushima Daiichi accident. Unfortunately, it’s taking people’s attention off of the true cost of the accident, in terms of both money and public health.

Placing the Olympics in Tokyo was and still is a ploy to minimize the consequences of the Fukushima Daiichi meltdowns and to take the public’s attention away from a pressing emergency that still needs resolution for the health and safety of the people of Japan.

Is life in Fukushima really getting back to normal? — The Washington Post

The big question

It’s been nearly eight years since the disaster at the Fukushima Daiichi nuclear power plant in Japan, which sent radiation plumes floating across the world and forced the evacuation of much of the surrounding area. Now, with the Olympics coming to Tokyo next year, Fukushima is being set up as a symbol of hope, recovery and a return to normalcy. But some of the area’s former residents remain afraid to come back, and towns still lie deserted despite government assurances. So we asked Post Tokyo bureau chief Simon Denyer, who recently visited the area: Is life in Fukushima really getting back to normal?

“That’s certainly the impression Prime Minister Shinzo Abe wants to create. The Olympic torch relay will start in Fukushima, and the city will host baseball and softball as well.

The city of Fukushima, perhaps 50 miles from the nuclear plant, is bustling, with radiation levels comparable to Hong Kong and London. Japan’s strict testing program shows that its farm and fisheries products are absolutely safe. Tourist arrivals and food exports from the prefecture have both recovered to beyond their pre-accident levels.

“But the towns nearest the plant offer a different story. Some areas remain off limits due to radiation, and the mountainous forests surrounding the area are virtually impossible to decontaminate. Even in towns that have been cleared for people to return, residents remain extremely wary — especially families with young children.

“In the town of Namie, cleared for resettlement two years ago, less than 5 percent of the pre-disaster population has returned. A sign telling customers to make themselves at home is still displayed in a bar, but debris litters the floor inside. A karaoke parlor is boarded up. Wild boars, monkeys and palm civets still roam the streets.

“In another town, I saw a deserted ramen restaurant — bowls, glasses, bottles of soy sauce and even a pack of cigarettes abandoned on the counter, as they were on March 11, 2011, when an earthquake and tsunami struck the region. The restaurant is still off-limits and coated in dust I wasn’t about to touch.

“The government says the plant itself may take 30 or 40 years to decommission, and the cleanup will cost $200 billion. But the technology does not yet exist to safely remove hundreds of tons of molten fuel from the stricken reactors. Independent experts say it could take much longer and cost much more.” ”

Remote-controlled probe picks up radioactive debris at Fukushima for the first time — Gizmodo

” Tepco, the state-owned operator of the badly damaged Fukushima nuclear plant, has conducted an important test in which a remote-controlled probe managed to grasp several small grains of radioactive debris, AFP reports. The successful operation marked an important achievement for the company as it prepares for a cleanup operation that could take decades.

In March 2011, the devastating Tōhoku earthquake and tsunami triggered the core meltdown of three reactors at the Fukushima Daiichi nuclear power plant. Eight years later, the plant’s operator, Tokyo Electric Power Company Holdings (Tepco), is still in the formative stages of devising a clean-up plan.

The primary challenge, of course, is dealing with the intense radiation emanating from the melted fuel. Two years ago, for example, a robot became unresponsive after just two hours in reactor No. 2; there’s enough radiation down there—approximately 650 sieverts per hour—to fry a person within a few seconds. The episode showed that technical advancements will be required to make robots more resilient to radiation near the core, and that the cleanup will likely take longer than expected.

Early last year, a camera attached to a remote-controlled probe was sent into reactor No. 2. Images confirmed that fuel debris had melted through the reactor pressure vessel (RPV), also known as the reactor core, dripping down into a collection chamber known as the primary containment vessel (PCV). Images of the chamber showed pebble- and clay-like deposits covering the entire bottom of the PCV pedestal. This accumulated waste, along with similar piles at reactors No. 1 and 3, needs to be cleaned up, and Tepco is currently trying to determine the best way of doing so.

To that end, the state-owned company devised an operation to see what that material is like and determine if it can be moved. On Wednesday February 13, Tepco sent a probe equipped with a remotely operated robotic hand down into the No. 2 lower chamber, Japan Times reports. Using its tong-like fingers, the probe picked up five grain-sized pieces of radioactive melted fuel. AFP reported that the pieces were moved to a maximum height of 2 inches (5 centimeters) above the bottom of the chamber. In addition to taking images with a camera, the probe measured radiation and temperature during the investigation, according to a Tepco release.

No radioactive debris was removed from the chamber, but the eight-hour-long operation showed that some of the melted fuel can be moved—an important bit of evidence that will inform future plans to clean up the plant. But as the Japan Times noted, one of the six areas explored by the probe contained debris that had solidified into a clay-like substance, which the robotic hand was unable to grasp. Future robots will need to slice or saw through this material such that it can be removed. That won’t be easy.

A future test, planned for April, will see some debris removed from the chamber, according to the Japan Times. Tepco has yet to disclose how and where this radioactive waste will be stored.

The company is hoping to start removing radioactive fuel in earnest by 2021, but the clean-up is expected to take decades, with some estimates suggesting it won’t be done until the 2050s. Many other technological hurdles still exist, such as determining the full extent of structural damage at the Fukushima plant, locating all the melted fuel in the three damaged reactors, and figuring out a way to remove the large quantities of contaminated water stored at the site.

If that all sounds overwhelming, well, it is. As we’ve said before, when nuclear power goes wrong, it really goes wrong. ”
