High levels of cesium radioactive material migrating down into soil around Fukushima — Global Research

” High levels of radioactive cesium remain in the soil near the Fukushima Daiichi nuclear power plant and these radionuclides have migrated at least 5 centimeters down into the ground at several areas since the nuclear accident five years ago, according to preliminary results of a massive sampling project being presented at the JpGU-AGU joint meeting in Chiba, Japan.

In 2016, a team of more than 170 researchers from the Japanese Geoscience Union and the Japan Society of Nuclear and Radiochemical Sciences conducted a large-scale soil sampling project to determine the contamination status and transition process of radioactive cesium five years after a major earthquake and tsunami caused a nuclear accident at the Fukushima Daiichi plant.

The team collected soil samples at 105 locations up to 40 kilometers (25 miles) northwest of the Fukushima Daiichi nuclear power plant in the “difficult-to-return” zone where entry is prohibited. The project seeks to understand the chemical and physical forms of radionuclides in the soil and their horizontal and vertical distribution.

The Japanese government has monitored the state of radioactive contamination in the area near the plant since the 2011 accident by measuring the air dose rate, but scientists can only determine the actual state of contamination in the soil and its chemical and physical forms by direct soil sampling, said Kazuyuki Kita, a professor at Ibaraki University in Japan, who is one of the leaders of the soil sampling effort.

Understanding the radionuclides’ chemical and physical forms helps scientists understand how long they could stay in the soil and the risk they pose to humans, plants and animals, Kita said. The new information could help in assessing the long-term risk of the radionuclides in the soil, and inform decontamination efforts in heavily contaminated areas, according to Kita, one of several researchers will present the team’s preliminary results at the JpGU-AGU joint meeting next week.

Preliminary results show high levels radioactive cesium are still present in the soil near the plant. The levels of radiation are more than 90 percent, on average, of what was found immediately following the accident, according to Kita.

Most of the radiocesium in the soil was found near the surface, down to about 2 centimeters, immediately following the 2011 accident. Five years later, at several sampling points, one-third to one-half of the radiocesium has migrated deeper into the soil, according to Kita. Preliminary results show the radiocesium moved about 0.3 centimeters per year, on average, deeper into the soil and soil samples show the radiocesium has penetrated at least 5 centimeters into the ground at several areas, according to Kita.

The team plans to analyze samples taken at greater depths to see if the radiocesium has migrated even further, he said.

“Most of the radioactive cesium remains after five years, but some parts of the radioactive cesium went from the surface to deeper soil,” he said.

Knowing how much radioactive contamination has stayed on the surface and how deep it has penetrated into the soil helps estimate the risk of the contaminants and determine how much soil should be removed for decontamination. The preliminary results suggest decontamination efforts should remove at least the top 6 to 8 centimeters of soil, Kita said.

The preliminary data also show there are insoluble particles with very high levels of radioactivity on the surface of the soil. Debris from the explosion fused with radiocesium to form small glass particles a few microns to 100 microns in diameter that remain on the ground, according to Kita. The team is currently trying to determine how many of these radiocesium glass particles exist in areas near the nuclear plant, he said.

“We are afraid that if such high radioactive balls remain on the surface, that could be a risk for the environment,” Kita said. “If the radioactivity goes deep into the soil, the risk for people in the area decreases but we are afraid the high radioactive balls remain on the surface.” “

Japan seeks final resting place for highly radioactive nuclear waste — Deutsche Welle

” With communities refusing to come forward to host the by-product of Japan’s nuclear energy industry, the Japanese government is drawing up a map of the most suitable locations for underground repositories.

The Japanese government is putting the finishing touches to a map of the country identifying what its experts consider to be the safest location for a repository for 18,000 tons of highly radioactive nuclear waste for the next 100,000 years. The map is expected to be released next month and will coincide with the government holding a series of symposiums across the country designed to explain why the repository is needed and to win support for the project.

Given that the disaster at the Fukushima Dai-ichi nuclear plant in March 2011 is still fresh in the memory of the Japanese public, the government’s plan is not expected to win much understanding or support.

The original proposal for a repository for the waste from the nation’s nuclear energy sector was first put forward in 2002, but even then there were few communities that were willing to be associated with the dump. Fifteen years later, and with a number of Japan’s nuclear reactors closed down for good in the wake of the Fukushima accident, the need for a permanent storage site is more pressing than ever.

Radioactivity release

The disaster, in which a 13-meter tsunami triggered by an off-shore earthquake crippled four reactors at the plant and caused massive amounts of radioactivity to escape into the atmosphere, also underlined just how seismically unstable the Japanese archipelago is and the need for the repository to be completely safe for 100,000 years.

Aileen Mioko-Smith, an anti-nuclear campaigner with Kyoto-based Green Action Japan, does not believe the government can deliver that guarantee.

“You only have to look at what happened in 2011 to realize that nowhere in Japan is safe from this sort of natural disaster and it is crazy to think otherwise,” she told DW.

Given the degree of public hostility, Mioko-Smith believes that the government will fall back on the tried-and-trusted tactic of offering ever-increasing amounts of money until a community gives in.

Government funds

“They have been trying to get this plan of the ground for years and one thing they tried was to offer money to any town or village that agreed to even undergo a survey to see if their location was suitable,” she said.

“There were a number of mayors who accepted the proposal because they wanted the money – even though they had no intention of ever agreeing to host the storage site – but the backlash from their constituents was fast and it was furious,” Smith added.

“In every case, those mayors reversed their decisions and the government has got nowhere,” she said. “But I fear that means that sooner or later they are just going to make a decision on a site and order the community to accept it.”

The security requirements of the facility will be exacting, the government has stated, and the site will need to be at least 300 meters beneath the surface in a part of the country that is not subject to seismic activity from active faults or volcanoes. It must also be safe from the effects of erosion and away from oil and coal fields. Another consideration is access and sites within 20 km of the coast are preferred.

High-level waste

The facility will need to be able to hold 25,000 canisters of vitrified high-level waste, while more waste will be produced as the nation’s nuclear reactors are slowly brought back online after being mothballed since 2011 for extensive assessments of their safety and ability to withstand a natural disaster on the same scale as the magnitude-9 earthquake that struck Fukushima.

Stephen Nagy, a senior associate professor of international relations at Tokyo’s International Christian University, agrees that the government will have to pay to convince any community to host the facility.

“They will probably peddle it as subsidies for rural revitalization, which is a tactic that all governments use, but there are going to be some significant protests because Fukushima has created a nuclear allergy in most people in Japan,” he said.

“I expect that the government would also very much like to be able to phase out nuclear energy, but that is simply not realistic at the moment,” he said.

When it is released, the government’s list is likely to include places in Tohoku and Hokkaido as among the most suitable sites, because both are relatively less populated than central areas of the country and are in need of revitalization efforts. Parts of Tohoku close to the Fukushima plant may eventually be chosen because they are still heavily contaminated with radiation from the accident. ”

Finding and removing melted fuel rods at Fukushima No. 1 — Nikkei Asian Review, The Japan Times

Nikkei Asian Review, “Survey fails to find melted rods at Fukushima reactors”:

” TOKYO — A remote survey of the Fukushima Daiichi nuclear plant’s No. 1 reactor was unable to locate and photograph melted nuclear fuel, Tokyo Electric Power Co. Holdings said Thursday, complicating efforts to remove that material as part of an extensive cleanup.

Tepco on Saturday sent a robot equipped with a camera into the containment vessel for the No. 1 unit. The majority of fuel rods have melted through the unit’s pressure vessel since the plant was struck by the March 11, 2011, earthquake and tsunami. The prevailing view has been that those melted fuel rods are now sitting under 2.5m of water at the bottom of the containment vessel.

The plan was to explore the bottom section by dipping a camera into the pool of water for the first time. But unexpected barriers such as pipes kept the camera around 1 meter from the bottom in most of the 10 positions surveyed instead of the intended depth of about 40cm from the bottom. While the camera was able to capture sand-like sediment, there was no trace of the melted fuel rods. Adding a fifth day to the investigation turned up no further evidence.

Yuichi Okamura, acting general manager of Tepco’s onsite nuclear power division, offered few comments at the utility’s Thursday news conference, saying only that “photographs and radiation data will need to be evaluated in conjunction with one another.”

The timeline set by Tepco and the government for decommissioning the Fukushima plant aims to begin extraction of melted-down material from the No. 1, No. 2 or No. 3 reactor in 2021 or earlier. An extraction plan is to be decided this summer. But the fact that the status of the melted rods still remains unknown underscores the seriousness of the accident.

The results of the robot survey were “limited,” according to Masanori Naitoh, director of nuclear safety analysis at the Institute of Applied Energy’s Nuclear Power Engineering Center. “It would be difficult to set a plan for extraction based on the information from this survey alone.”

An investigation of the No. 2 reactor also fell short, with the survey robot unable to reach the targeted spot right under the unit’s pressure vessel. ”

The Japan Times, “Tepco’s biggest hurdle: How to remove melted fuel from crippled Fukushima reactors”:

” Six years after the triple meltdown at the Fukushima No. 1 nuclear power plant, recent investigations underneath the damaged reactor 2 using cameras and robots came close to identifying melted fuel rods for the first time.

Experts say getting a peek inside the containment vessel of reactor 2 was an accomplishment. But it also highlighted how tough it will be to further pinpoint the exact location of the melted fuel, let alone remove it some time in the future.

The biggest hurdle is the extremely lethal levels of radiation inside the containment vessel that not only prevent humans from getting near but have also crippled robots and other mechanical devices.

Safely removing the melted fuel would be a best-case scenario but the risks and costs should be weighed against the option of leaving the melted fuel in the crippled reactors, some experts said.

“The work to probe inside the containment vessels and remove the fuel debris will be extremely tough because of the high radiation levels,” said Hiroshi Miyano, who heads a panel of the Atomic Energy Society of Japan, which is discussing ways to decommission the Fukushima plant and making recommendations to the government.

The government and Tokyo Electric Power Company Holdings Inc. are trying to find a way to remedy the situation but existing methods and technologies may not be sufficient, Miyano said.

In search of melted fuel

The world’s attention turned to the melted fuel rods in late January when Tepco inserted a 10-meter-plus tube equipped with a camera into the containment vessel of reactor 2 to capture images under the pressure vessel that housed the fuel rods.

The images showed black lumps scattered beneath the pressure vessel.

When the March 11, 2011, Great East Japan Earthquake and monstrous tsunami hit, the plant suffered a blackout and lost its key cooling system, triggering meltdowns in reactors 1, 2 and 3. The melted nuclear fuel rods penetrated the pressure vessels and fell into the containment vessels.

Tepco had put cameras inside the containment vessels several times in the past six years but January’s probe was the first to apparently find melted fuel debris.

“We understand that this is a big milestone. We could finally get to see what it was like underneath the pressure vessel,” said Yuichi Okamura, general manager of Tepco’s nuclear power and plant siting division.

“This is critical information in order to remove the fuel debris.”

Radiation barrier

But Tepco hasn’t confirmed that the black lumps are melted fuel, saying they could be paint or cable wrappings, and further investigation is needed.

Capturing the images may be progress but the robot and camera forays have not provided enough information about how to deal with the melted fuel.

Last month, Tepco sent a remote-controlled, scorpion-shaped robot in to further probe inside the reactor 2 containment vessel. But the robot failed before it reached under the pressure vessel after a tire became stuck.

The robot’s dosimeter measured radiation levels of 210 sieverts per hour — enough to kill humans instantly.

While 210 sieverts per hour indicate the melted fuel was nearby, the radiation crippled the robot’s electronics, including its semiconductors and cameras, indicating that the further use of robots to pinpoint the melted fuel will be difficult, robotics experts said.

There are computer chips “designed to withstand a certain level of radiation, but the level inside the containment vessel is totally different,” said Satoshi Tadokoro, a professor at Tohoku University who is an expert on disasters and rescue robots.

The radiation can damage a robot’s chips that serve as their brains, causing the devices to lose control, said Tadokoro, whose robots have also been used at the Fukushima plant.

“On top of the high level of radiation, the entrance (to the containment vessel) for the robot is very small,” restricting what types of robots can be used to hunt for the melted fuel, he said.

Tepco said the opening it created on the side of the reactor 2 containment vessel is about 11 cm in diameter.

Fuel removal strategy

Tepco is set to conduct internal probes of the reactor 1 containment vessel this month and is preparing similar missions for reactor 3.

The government and utility then plan to adopt a basic fuel removal strategy this summer and fine-tune the plan next year, with the actual fuel removal taking place in or after 2021.

There are essentially three options for the strategy, according to the Tokyo-based International Research Institute for Nuclear Decommissioning (IRID), which is developing technologies for the Fukushima plant decommission.

One option is to flood the containment vessels with water and use a crane above the reactors to hoist up the melted fuel. The second option is to carry out the same process but without water. The third is to install removal equipment through the side of the containment vessel.

There are merits and drawbacks to each option, said Shoji Yamamoto, who heads the team developing technologies to create the fuel removal devices at IRID.

The flooding option can block radiation using water, but if the fuel melts into the water, it could pose a risk of recriticality. The debris may need to be cut into pieces for removal, but this process would enable water to get between multiple pieces, creating the condition for recriticality. For nuclear chain reactions to happen there needs to be a certain distance between nuclear fuel and water.

If there is no water, the recriticality risk is minimal but the massive radiation levels cannot be blocked, Yamamoto said.

Tepco’s Okamura said being able to block radiation with water is a huge plus, but noted the reactor 2 containment vessel had cracks and holes that could let injected coolant water escape.

With the Three Mile Island nuclear accident in the U.S., the flooding option was used to retrieve the melted fuel in the 1980s. But the key difference was that all of the melted fuel stayed inside the pressure vessel, so it was easier to flood the reactor.

Because the melted fuel in reactors 1, 2 and 3 at the Fukushima plant all penetrated the pressure vessels and fell into the containment vessels, extracting it from the top or the side was a tough call, Yamamoto said, noting it was important to know the exact location of the melted fuel.

The distance between the top of the pressure vessel and the bottom of the containment vessel is about 45 meters and some parts inside the pressure vessels will need to be removed if Tepco tries to remove the debris inside the containment vessels from the top.

“If we know that the melted fuel is concentrated in the containment vessels, it will be more efficient to remove it from the side” because the entry point is closer, Yamamoto said.

Whatever option is decided, Yamamoto stressed that maintaining the fuel removal device will be difficult because the radiation will probably cripple it.

“The fuel removal device will be controlled remotely … it will be broken somewhere down the line and the parts will have to be replaced, considering its (ability to withstand) radiation,” he said.

“Given that, maintenance will have to be done remotely, too, and that will be a big challenge.”

To remove or not

Another option altogether is for Tepco to leave the melted fuel where it is.

During a media tour of the Fukushima No. 1 plant last month, Okamura of Tepco said the utility intended to collect the melted fuel because leaving it was “not an appropriate way” to manage nuclear fuel.

Miyano of the Atomic Energy Society of Japan said the debris must be removed because radioactive materials, including nuclear fuel, must be strictly controlled under international rules requiring strict monitoring.

Domestic nuclear power plant operators have to report the amount of nuclear fuel they have to the Nuclear Regulation Authority, which then reports to the International Atomic Energy Agency.

“There is the question of whether the government and Tepco decide not to remove the fuel debris. That would be an international issue,” said Miyano, adding that a consensus from the international community would be needed.

At the same time, Miyano said debate and analysis will be required to decide which choice would be best by looking at various factors, including how much it will cost to pick up all the melted fuel and where to store it. ”

Six years after Fukushima, much of Japan has lost faith in nuclear power — The Conversation

” Six years have passed since the Fukushima nuclear disaster on March 11, 2011, but Japan is still dealing with its impacts. Decommissioning the damaged Fukushima Daiichi nuclear plant poses unprecedented technical challenges. More than 100,000 people were evacuated but only about 13 percent have returned home, although the government has announced that it is safe to return to some evacuation zones.

In late 2016 the government estimated total costs from the nuclear accident at about 22 trillion yen, or about US$188 billion – approximately twice as high as its previous estimate. The government is developing a plan under which consumers and citizens will bear some of those costs through higher electric rates, taxes or both.

The Japanese public has lost faith in nuclear safety regulation, and a majority favors phasing out nuclear power. However, Japan’s current energy policy assumes nuclear power will play a role. To move forward, Japan needs to find a new way of making decisions about its energy future.

Uncertainty over nuclear power

When the earthquake and tsunami struck in 2011, Japan had 54 operating nuclear reactors which produced about one-third of its electricity supply. After the meltdowns at Fukushima, Japanese utilities shut down their 50 intact reactors one by one. In 2012 then-Prime Minister Yoshihiko Noda’s government announced that it would try to phase out all nuclear power by 2040, after existing plants reached the end of their 40-year licensed operating lives.

Now, however, Prime Minister Shinzo Abe, who took office at the end of 2012, says that Japan “cannot do without” nuclear power. Three reactors have started back up under new standards issued by Japan’s Nuclear Regulation Authority, which was created in 2012 to regulate nuclear safety. One was shut down again due to legal challenges by citizens groups. Another 21 restart applications are under review.

In April 2014 the government released its first post-Fukushima strategic energy plan, which called for keeping some nuclear plants as baseload power sources – stations that run consistently around the clock. The plan did not rule out building new nuclear plants. The Ministry of Economy, Trade and Industry (METI), which is responsible for national energy policy, published a long-term plan in 2015 which suggested that nuclear power should produce 20 to 22 percent of Japan’s electricity by 2030.

Meanwhile, thanks mainly to strong energy conservation efforts and increased energy efficiency, total electricity demand has been falling since 2011. There has been no power shortage even without nuclear power plants. The price of electricity rose by more than 20 percent in 2012 and 2013, but then stabilized and even declined slightly as consumers reduced fossil fuel use.

Japan’s Basic Energy Law requires the government to release a strategic energy plan every three years, so debate over the new plan is expected to start sometime this year.

Public mistrust

The most serious challenge that policymakers and the nuclear industry face in Japan is a loss of public trust, which remains low six years after the meltdowns. In a 2015 poll by the pro-nuclear Japan Atomic Energy Relations Organization, 47.9 percent of respondents said that nuclear energy should be abolished gradually and 14.8 percent said that it should be abolished immediately. Only 10.1 percent said that the use of nuclear energy should be maintained, and a mere 1.7 percent said that it should be increased.

Another survey by the newspaper Asahi Shimbun in 2016 was even more negative. Fifty-seven percent of the public opposed restarting existing nuclear power plants even if they satisfied new regulatory standards, and 73 percent supported a phaseout of nuclear power, with 14 percent advocating an immediate shutdown of all nuclear plants.

Who should pay to clean up Fukushima?

METI’s 22 trillion yen estimate for total damages from the Fukushima meltdowns is equivalent to about one-fifth of Japan’s annual general accounting budget. About 40 percent of this sum will cover decommissioning the crippled nuclear reactors. Compensation expenses account for another 40 percent, and the remainder will pay for decontaminating affected areas for residents.

Under a special financing scheme enacted after the Fukushima disaster, Tepco, the utility responsible for the accident, is expected to pay cleanup costs, aided by favorable government-backed financing. However, with cost estimates rising, the government has proposed to have Tepco bear roughly 70 percent of the cost, with other electricity companies contributing about 20 percent and the government – that is, taxpayers – paying about 10 percent.

This decision has generated criticism both from experts and consumers. In a December 2016 poll by the business newspaper Nihon Keizai Shimbun, one-third of respondents (the largest group) said that Tepco should bear all costs and no additional charges should be added to electricity rates. Without greater transparency and accountability, the government will have trouble convincing the public to share in cleanup costs.

Other nuclear burdens: Spent fuel and separated plutonium

Japanese nuclear operators and governments also must find safe and secure ways to manage growing stockpiles of irradiated nuclear fuel and weapon-usable separated plutonium.

At the end of 2016 Japan had 14,000 tons of spent nuclear fuel stored at nuclear power plants, filling about 70 percent of its onsite storage capacity. Government policy calls for reprocessing spent fuel to recover its plutonium and uranium content. But the fuel storage pool at Rokkasho, Japan’s only commercial reprocessing plant, is nearly full, and a planned interim storage facility at Mutsu has not started up yet.

The best option would be to move spent fuel to dry cask storage, which withstood the earthquake and tsunami at the Fukushima Daiichi nuclear plant. Dry cask storage is widely used in many countries, but Japan currently has it at only a few nuclear sites. In my view, increasing this capacity and finding a candidate site for final disposal of spent fuel are urgent priorities.

Japan also has nearly 48 tons of separated plutonium, of which 10.8 tons are stored in Japan and 37.1 tons are in France and the United Kingdom. Just one ton of separated plutonium is enough material to make more than 120 crude nuclear weapons.

Many countries have expressed concerns about Japan’s plans to store plutonium and use it in nuclear fuel. Some, such as China, worry that Japan could use the material to quickly produce nuclear weapons.

Now, when Japan has only two reactors operating and its future nuclear capacity is uncertain, there is less rationale than ever to continue separating plutonium. Maintaining this policy could increase security concerns and regional tensions, and might spur a “plutonium race” in the region.

As a close observer of Japanese nuclear policy decisions from both inside and outside of the government, I know that change in this sector does not happen quickly. But in my view, the Abe government should consider fundamental shifts in nuclear energy policy to recover public trust. Staying on the current path may undermine Japan’s economic and political security. The top priority should be to initiate a national debate and a comprehensive assessment of Japan’s nuclear policy. ”

Asking the tough questions on Fukushima — The Japan Times

” In January, regional newspaper Fukushima Minpo interviewed Yosuke Takagi, state minister of economy, trade and industry. While talking about reconstruction plans for areas near the crippled Fukushima No. 1 nuclear power plant, Takagi mentioned resurrecting Dash-mura (Dash Village), a farm created from scratch by boy band Tokio for its Nippon TV series “The Tetsuwan Dash.”

The location of Dash-mura was always secret, lest Tokio’s fans descend on the project and destroy its rustic purity. But following the reactor accident caused by the Great East Japan Earthquake, it was revealed that the farm was in an area declared off-limits due to its proximity to the plant. It was promptly abandoned.

A different news outlet, Fukushima Minyu, clarified that the revival of Dash-mura is “nothing more than a personal idea of Takagi’s,” but that he intends to discuss it with related parties. An 80-year-old farmer who once worked with Tokio on the project told Minyu that bringing back the farm would be a great PR boost for the area’s agriculture, which is obviously Takagi’s aim. The show’s producer, however, after hearing of Takagi’s comment, tweeted that he knew nothing about the news, adding cryptically that “Dash-mura is no one’s thing.”

The Huffington Post called the Ministry of Economy, Trade and Industry to ask if it had any intention of reviving Dash-mura. A representative only “confirmed” that Takagi had “made such a comment” and said METI had no “definite plan” to that end but might “study it.”

Nevertheless, the idea fits in with the government’s goal of getting former residents to move back to the area. Last week, authorities announced they would further reduce the evacuation zone at the end of the month, which means it will have shrunk by 70 percent since April 2014. The concern is that few people want to return. Some have already made lives for themselves elsewhere and see a lack of opportunity in their old communities.

Many also remain suspicious of the government’s assurances that radioactivity has dropped to a safe level. There is still debate among experts as to whether or not the radiation in the area is dangerous. The government says that the problems caused by the accident are now “under control,” and affected residents can soon go back to their old lives.

One media outlet who has challenged this assumption is TV Asahi’s “Hodo Station.” On March 9, the nightly news show sent its main announcer, Yuta Tomikawa, to Iitate, a village located about 40 km from the crippled nuclear facility. All 6,000 residents were eventually evacuated after the accident.

Standing in front of rows of black plastic bags, Tomikawa reported that, according to the government, decontamination efforts have been a success. A safe annual radiation level is 1 millisievert, but a local dairy farmer told Tomikawa that his own readings showed five times that level, adding that 70 percent of Iitate is wooded and forest land had not been decontaminated yet.

Moreover, the government is lifting the evacuation order for any areas where annual radiation levels are “no more than” 20 mSv. The International Commission on Radiological Protection told the government that once the situation had stabilized in the affected areas, people could return if radiation dropped to between 1 and 20 mSv, but the lower the better. Exposure to 20 mSv for a short period may not be a problem, but it could have harmful effects in the long run.

Tomikawa did not say that people who returned to Iitate would be in danger, but he did imply that the government is manipulating numbers in an attempt to persuade evacuees to return to their homes.

The web magazine Litera wrote that TV Asahi is the only mainstream media outlet to question the government line in this regard. Actually, Nippon TV did something similar, albeit indirectly. Last month, it rebroadcasted an episode of its “NNN Document” series about the married manzai (stand-up comedy) duo Oshidori Mako-Ken’s efforts to come to terms with the Fukushima meltdowns and their aftermath.

The couple belongs to the large Osaka-based entertainment company Yoshimoto Kogyo, but ever since the disaster Mako has attended about 500 related news conferences, making a nuisance of herself by plying Tokyo Electric Power Company Holdings employees and government officials with questions the mainstream media don’t usually ask.

In order to gain access to the news conferences, she offered stories to the weekly magazine Spa! Her editor there told Nippon TV that Mako is now respected or resented by a lot of full-time journalists, partly because she’s a geinojin (entertainer) who has proved her mettle as a reporter, but mainly because of her hard-line queries, which put her interlocutors on the spot.

Following the disaster, Mako became suspicious when she saw people fleeing Tokyo in large numbers but heard nothing about it on the news. In order to make sense of the situation she’d watch unfiltered news conferences about the disaster on the internet. She realized only independent reporters asked tough questions, so she started attending them herself as a proxy for average people who didn’t understand what was going on. The more officials obfuscated, the more she studied.

She’s now recognized by some foreign press as one of the most informed persons on the subject — she even received a letter of encouragement from Pope Francis — and yet she’s shunned by the Japanese press. Nevertheless, she has dedicated followers, including workers cleaning up the reactor who often feed her questions to ask of officials. She’s won awards for her work, but from citizens groups, not media groups.

Nowadays, Mako and Ken do more free lectures on Fukushima No. 1 than they do comedy shows. One of their main themes is that media reports tend to confuse the public rather than inform them, but that’s really the fault of the government, which would like nothing better than for people to feel as if nothing ever happened. ”

Japan considering using Fukushima soil for public parks — TRUNEWS

” The Japanese government may buy [contaminated soil], using soil from the Fukushima prefecture as landfill for “green areas” and parks, potentially subjecting citizens to dangerous radiation.

The advisory panel of the Environment Ministry on Monday proposed reusing soil that was contaminated during the Fukushima nuclear meltdown of 2011 as part of future landfills designated for public use, Kyodo news reported.

In its proposal, the environmental panel avoided openly using the word “park” and instead said “green space,” apparently to avoid a premature public outcry, Mainichi Shimbun reported.

Following an inquiry from the news outlet, the Ministry of the Environment clarified that “parks are included in the green space.”

In addition to decontaminating and recycling the tainted earth for new parks, the ministry also stressed the need to create a new organization that will be tasked with gaining public trust about the prospects of such modes of recycling.

To calm immediate public concerns, the panel said the decontaminated soil will be used away from residential areas and will be covered with a separate level of vegetation to meet government guidelines approved last year.

In June last year, the Ministry of the Environment decided to reuse contaminated soil with radioactive cesium concentration between 5,000 to 8,000 becquerels per kilogram for public works such as nationwide roads and tidal banks.

Under these guidelines, which can now be extended to be used for the parks, the tainted soil shall be covered with clean earth, concrete or other materials.

Such a landfill, the government said at the time, will not cause harm to nearby residents as they will suffer exposure less than 0.01 mSv a year after the construction is completed.

The Fukushima Daiichi nuclear power plant suffered a blackout and subsequent failure of its cooling systems in March 2011, when it was hit by an earthquake and a killer tsunami that knocked out the facility, spewing radiation and forcing 160,000 people to flee their homes. Three of the plant’s six reactors were hit by meltdowns, making the Fukushima nuclear disaster the worst since the Chernobyl catastrophe in 1986. ”
