Work starts in Fukushima on intermediate waste facility — The Asahi Shimbun

” The Environment Ministry on Nov. 15 started building a facility in Fukushima Prefecture that will store radiation-contaminated debris for up to 30 years, despite obtaining permission for only 11 percent of the site.

The 16-square-kilometer storage facility is expected to hold up to 22 million cubic meters of materials contaminated by radioactive fallout from the disaster at the Fukushima No. 1 nuclear power plant in March 2011.

“I hope that you take pride in this project and cooperate to construct the facility,” Tadahiko Ito, a vice environment minister, told workers.

The facility, which will span the towns of Futaba and Okuma, is expected to start accepting, sorting and storing the debris in autumn 2017 at the earliest, more than two-and-a-half years later than the initial schedule of January 2015.

The project has been delayed because the ministry has faced difficulties buying or borrowing land for the project.

In fact, only 445 of the 2,360 landowners of plots at the site have agreed to sell or lend their properties to the ministry for the storage facility as of the end of October.

Many of the reluctant landowners, who possess 89 percent of the land, fear the contaminated waste will remain at the facility well beyond 30 years.

The government has worked out a bill stipulating that contaminated materials kept in the intermediate storage facility will be moved out of Fukushima Prefecture in 2045. However, the government has yet to decide on the location of the final disposal site.

A huge cleanup operation after the triple meltdown at the Fukushima nuclear plant collected tons of radioactive soil and debris.

In March 2015, the ministry borrowed land and created a “temporary storage place” within a 16-square-km site on an experimental basis.

However, only about 70,000 cubic meters of the waste has been taken to the temporary storage site as of the end of October. The remaining waste, exceeding 10 million cubic meters, is being tentatively stored at about 150,000 locations in the prefecture.

“If the transportation of contaminated materials to the intermediate storage facility proceeds, the waste currently stored in residential areas and at company compounds will be transported there,” said an official of the Fukushima prefectural government’s section in charge of decontamination. ”

Fukushima: A second Chernobyl? — The Asia-Pacific Journal

” Waiting for the Future in Fukushima

As the sixth anniversary of the Fukushima nuclear disaster approaches, the area around the hulking corpse of the Fukushima Daiichi Nuclear Power Plant continues to exude a horrible fascination. Arkadiusz Podniesinski is one of thousands of photographers and journalists drawn there since the crisis began in March 2011. In 2015 his first photo report from the area attracted millions of views around the world.

Podniesinski brought to Japan his experience of chronicling the aftermath of the world’s worst nuclear accident in Chernobyl, which he first visited in 2008. It was, he noted, people, not technology that was responsible for both disasters. Japanese politicians, he adds, are offended by comparisons with Chernobyl. Still, rarely for a foreign report on Fukushima, his work was picked up by Japanese television (on the liberal channel TBS), suggesting there is a hunger for this comparative perspective.

Podniesinski’s first trip strengthened his belief in the “catastrophic consequences of nuclear disasters.” Apart from the suffering caused by the disruption of so many lives (160,000 people remain homeless or displaced), there is the struggle to return contaminated cities and towns to a state where people can live in them again. Billions of dollars have already been spent on this cleanup and much more is to come: The latest rehabilitation plan by plant operator Tokyo Electric Power Co. puts the total bill for compensation alone at 7.08 trillion yen, or nearly $60 billion.

Thirty years after Chernobyl’s reactor exploded, Ukrainians have long come to terms with the tragedy that befell them, he writes. The dead and injured have been forgotten. A 2-billion-Euro sarcophagus covering the damaged reactor is nearly complete. The media returns to the story only on major anniversaries. What, he wonders, will become of Fukushima? Last year, Naraha became the first town in Fukushima Prefecture to completely lift an evacuation order imposed after the triple meltdown. But despite rebuilding much of the town’s infrastructure and spending millions of dollars to reduce radiation, the local authorities have persuaded only a small number of people to permanently return there.

Radiation is only part of the problem, of course. “The evacuees worry about the lack of schools, hospitals and shops,” says Podniesinski. “About the public infrastructure, which has not been sufficiently rebuilt. It must be adapted to the needs of older people, who, after the departure of so many young people from the zone, will now be the majority. However, the evacuees are most afraid of loneliness, as few of their family members, friends and neighbors have decided to return.”

The sense of life suspended, of waiting for the future to arrive, resonates in Tomioka, once home to nearly 16,000 people, now a ghost town. Podniesinski arrives just as its famous cheery blossoms bloom, but there is nobody to see them. The irony of fate, he writes, means that this Japanese symbol of new, nascent life blooms in contaminated and lifeless streets. “Will the city and its residents be reborn? Undoubtedly, the last word shall belong to them alone.” DM “

introduction by David McNeill

” Fukushima: A Second Chernobyl?

Exactly a year has passed since my first visit to Fukushima. A visit which strengthened my belief of how catastrophic the consequences of nuclear disasters can be. A visit that also highlighted how great the human and financial efforts to return contaminated and destroyed cities to a state suitable for re-habitation can be.

The report on the Fukushima zone through the eyes of a person who knows and regularly visits Chernobyl received a great deal of interest in the international community. Viewed several million times and soon picked up by traditional media around the world, it became for a moment the most important topic on Fukushima. I was most pleased, however, by the news that the coverage also reached Japan, where it not only caused quite a stir (more on that another time) but also made me realize just how minuscule Japanese knowledge about the current situation in Fukushima is.

As a result, over the last year I started to go to Fukushima more often than to Chernobyl. This is hardly surprising for another reason. 30 years have passed since the Chernobyl disaster, so the majority of Ukrainians have long since come to terms with the tragedy. The dead and injured have been forgotten. The same is true for media interest, which is only revived on the occasion of the round, 30th anniversary of the disaster. In addition, after nearly 10 years and 2 billion euros, work on the new sarcophagus is finally coming to an end, and soon a storage site for radioactive waste and a 227-ha radiological biosphere reserve will be established.

Will the decommissioning of the power plant in Fukushima also take 30 years and end with the construction of a sarcophagus? Will the contaminated and deserted towns located around the destroyed Fukushima Daiichi power plant be called ghost towns and resemble Chernobyl’s Pripyat? Finally, will Fukushima become a popular place for dark tourism like Chernobyl and be visited by thousands of tourists every year?

I Never Want to Return Alone

The Japanese, particularly politicians and officials, do not like and are even offended by comparisons between Fukushima and Chernobyl. It is, however, difficult not to do so when analogies are visible everywhere. While the fact that the direct causes of the disasters are different, the result is almost identical. A tragedy for the hundreds of thousands of evacuated residents, hundreds of thousands of hectares of land contaminated, and decades of time and billions of dollars devoted to eliminating the results of the disaster. And the first cases of thyroid cancer.

The situation in Fukushima resembles a fight against time or a test of strength. The government has devoted billions of dollars to decontaminating the area and restoring residents to their homes. They must hurry before the residents completely lose hope or the desire to return. Before the houses collapse or people are too old to return to. In addition, the authorities soon intend to stop the compensation paid to residents, which according to many of them will be an even more effective “encouragement” for them to return. Deprived of financial support, many residents will have no other choice but to return. Many young families are not waiting for any government assistance. They decided long ago to leave in search of a new life free of radioactive isotopes. They will surely never return.

But radiation is not the only problem that the authorities must worry about. The evacuated residents worry about the lack of schools, hospitals and shops. About the public infrastructure, which has not been sufficiently rebuilt. It must be adapted to the needs of older people, who, after the departure of so many young people from the zone, will now be the majority. However, the evacuees are most afraid of loneliness, as few of their family members, friends and neighbours have decided to return.

Can the authorities manage to convince the residents to return? Has critical mass been exceeded, after which evacuees will learn from others and return? The authorities are doing everything they can to convince residents that the sites are safe for people. They open towns, roads and railway stations one after another. Unfortunately, despite this, residents still do not want to return. A recent survey confirms that there is a huge gap between the government’s current policies and the will of the affected residents. Only 17.8% want to return, 31.5% are unsure and 48% never intend to return.

It Became Chernobyl Here

During my first visit to Fukushima, I met Naoto Matsumura, who defied official bans and returned to the closed zone to take care of the animals abandoned there by farmers fleeing radiation. Matsumura has taken in hundreds of animals, saving them from inevitable death by starvation or at the hands of the merciless officials forcing farmers to agree to kill them. Thanks to his courage and sacrifice, Matsumura soon became known as the Guardian of Fukushima’s Animals.

Matsumura was not able to help all of the animals, however. According to the farmer, a third of them died of thirst, unable to break free of the metal beams in barns, wooden fences or ordinary kennels. Matsumura took me to one such place.

Not all appreciate Matsumura’s sacrifice and courage. Many people believe that helping these animals, which sooner or later would have ended up on a plate, is not worth the risk the farmer is exposing himself to. Matsumura always has the same answer for them – there is a fundamental difference between killing animals for food and killing animals who are no longer needed due to radiation.

Cow Terrorist

I also returned to Masami Yoshizawa, who like Naoto Matsumura decided to illegally return to the closed zone to take care of the abandoned animals. Shortly after the disaster, some of the farmer’s cows began to develop mysterious white spots on their skin. According to Yoshizawa, they are the result of radioactive contamination and the consumption of radioactive feed.

Yoshizawa’s farm is located 14 km from the destroyed power plant. From this distance, the buildings of the plant are not visible, but its chimneys can be seen. And, as Yoshizawa says – one could also see [and hear] explosions in the power plant as well as radioactive clouds that soon pass over his farm. Consequently, nearly half of the nearly 20,000 inhabitants of the town of Namie were evacuated to Tsushima, located high in the nearby mountains. But soon people began to flee from there when it turned out that the wind blowing in that direction contaminated the area even more. As a result of the radioactive contamination in Fukushima, a new generation known as the hibakusha has arisen. Up to now, this name was only given to people who were victims of the atomic bombings of Hiroshima and Nagasaki. Now this concept has also been applied to victims of the Fukushima nuclear disaster. As Yoshizawa says – of the 120 surveyed hibakusha, he ranks third in Namie in terms of the amount of radiation doses received.

Defying the completely ignorant authorities, Yoshizawa quickly became a professional activist and his cows got a new mission – they became protestors. And, soon after, he brought one of them in front of the Ministry of Agriculture’s building, demanding that research be undertaken to explain why white spots have appeared on the animals’ skins after the disaster. Yoshizawa says, “I protested [by] bringing a bit of Fukushima to Tokyo. May the cows and I become living proof of the disaster, and the farm a chronicle telling the story of the Fukushima disaster.”

When protesting against the construction and re-starting of subsequent nuclear power plants, Yoshizawa does not bring his cows along anymore. Instead, he has a car festooned with banners that pulls behind it a small trailer with a metal model of a cow. “I have a strong voice and can scream louder than die-hard right wingers!” explains Yoshizawa. “I’m a cowboy, a cow terrorist, a kamikaze!” he adds in a loud voice, presenting an example of his capabilities. “We are not advocating violence, we don’t kill people, we are not aggressive. We are political terrorists,” he concludes calmly. And after a moment, he invites us to a real protest. The occasion of the planned opening of the railway station is to be attended by Prime Minister Sinzo Abe himself.

The protest goes peacefully indeed. Yoshizawa first drives round the city to which the Prime Minister is soon to arrive. Driving his car, he shouts into the microphone, “When a fire broke out in the reactors, TEPCO employees fled. The fire was extinguished by the young men of the Japanese Self-Defence Forces. Why were you not able to control the power plant you built?” He continued immediately, “Today the Prime Minister is coming here. Let’s get up and greet Abe. Let’s show Abe not only the beautifully prepared railway station, let him also see the dark side of the city. For 40 years, we supplied electricity to Tokyo. Our region only could support Japan’s economic development. And now we suffer. Tales about the safety of nuclear power plants are a thing of the past,” Yoshizawa concludes. When the moment of the Prime Minister’s arrival approaches and the crowds grow larger, policemen and the Prime Minister’s security detail approach the farmer. They order him to take down his banners and leave the site. Yoshizawa obeys, but carries out their commands without haste. As if deliberately trying to prolong their presence, hoping to have time to meet and “greet” the Prime Minister.

No-go Zones

As always, a major part of my trip to Fukushima is devoted to visits to no-go zones. Obtaining permission to enter and photograph the interior is still difficult and very time-consuming. However, it is nothing compared to the search for owners of the abandoned properties, persuade them to come, show their houses and discuss the tragic past.

Sometimes, however, it’s different. Such as in the case of Tatsuo and Kazue Kogure, who with the help of Japanese television agreed to take me to Tomioka, where they ran a small but popular bar. It was not only a place to eat and drink sake, but also to sing karaoke with the bar’s owners.

Unfortunately the city, and with it the bar, stood in the way of the radioactive cloud and had to be closed. Earlier, I saw many similar bars and restaurants. Overgrown, smelly, full of mould, debris and scattered items. This place, however, is different. It is distinguished by its owners, who despite age and the tragedy they experienced, did not give up and opened a new bar outside the radioactive zone. Mr and Mrs Kogure not only showed me the abandoned bar, but also invited me to their new one.

What is unusual and extremely gratifying is the fact that the couple’s efforts to continue the family business are also supported by regular customers from the previous bar. “It’s thanks to their help that we could start all over again,” Kazue Kogure acknowledges. She immediately adds, “By opening the bar again we also wanted to be an example to other evacuated residents. To show that it’s possible.”

The Scale of the Disaster Shocked Us

I also visit the former fire station located in the closed zone in Tomioka. Due to the nuclear power plant neighbouring the city, the firefighters working here were regularly trained in case of a variety of emergencies. I am accompanied by Naoto Suzuki, a firefighter who served here before the disaster. In the middle of the firehouse, my attention is drawn to a large blackboard. “That’s the task scheduler for March 2011,” the firefighter explains. “On 11 March, the day of the disaster, we had nothing planned, but,” he adds with an ironic smile, “the day before we had a training session on responding to radioactive contamination. We practiced how to save irradiated people and how to use dosimeters and conduct decontamination.”

Unfortunately, the reality shocked even the firefighters, who had to cope with tasks they had never practiced. For example, with cooling the reactors. Even the repeatedly practiced evacuation procedures for the residents were often ineffective and resulted in the opposite of the desired effect. It turned out that the data from SPEEDI (System for Predicting Environmental Emergency Dose Information), whose tasks included forecasting the spread of radioactive substances, was useless and did not reach the local authorities. As a result, many residents were evacuated for more contaminated sites and unnecessarily endangered by the additional dose of radiation.

The monthly work schedule at the fire station in Tomioka (no-go zone). Firefighter Naoto Suzuki shows the training session on how to help people exposed to radiation planned for the day before the disaster. A committee meeting to provide information in the event of a fire in the nuclear reactors was planned for 14 March.

In the spring of this year, thanks to the help and support of many people, particularly the local authorities, evacuated residents and even a monk, I was also able to see many interesting places mostly located in the closed zones in Tomioka, Okuma, Futaba and Namie. Although five years have passed since the disaster, most of them still remain closed and many valuable objects can still be found there. Due to this, I have decided not to publish information that could aid in locating them.

Hope

Ending my series of travels around Fukushima, I return to Tomioka to see the thing for which the city is most famous and its residents most proud – one of the longest and oldest cherry blossom tunnels in Japan. For the residents of Tomioka, cherry trees have always been something more than just a well-known tourist attraction or the historic symbol of the town. Not only did they admire the aesthetic attributes of the flowers, but they were also part of their lives, organized festivals, meetings and the topic of family conversations.

The natural beauty and powerful symbolism as well as their constant presence in Japanese arts have made cherry trees become an icon of Japanese cultural identity. They signal the arrival of spring, the time for renewal and the emergence of new life. In the spiritual sense, they remind us of how beautiful, yet tragically short and fragile, life is – just like the blooming cherry blossoms that fall from the tree after just a few days.

The nuclear irony of fate meant that this Japanese symbol of new, nascent life today blooms in the contaminated and lifeless streets of Tomioka. Will the city and its residents be reborn, along with the cherry trees blossoming in solitude and silence? Undoubtedly, the last word shall belong to them alone. ”

Film focuses on ‘irradiated’ cattle kept alive in Fukushima — The Asahi Shimbun

” OSAKA–For some cattle farmers in Fukushima Prefecture, the thought of destroying their herds is too painful to bear even if they are contaminated with radioactive fallout.

A new documentary to be shown here this week records the plight of these farmers, who continue to look after their beef cattle in defiance of a government request to euthanize the animals.

“I took on this project because I wanted to capture what is driving farmers to keep their cattle. For all the trouble it is worth, the animals are now worthless,” said Tamotsu Matsubara, a visual director who shot the documentary.

Four years in the making, “Hibaku-ushi to Ikiru” (Living with irradiated cattle) is set for its first screening on Aug. 26 at a local community center in the city.

Matsubara’s interactions with the cattle farmers date to the summer of 2011, a few months after the nuclear crisis unfolded at the Fukushima No. 1 nuclear power plant following the Great East Japan Earthquake and tsunami on March 11 that year. His assignment was to cover a traditional festival in Minami-Soma, which is located near the stricken nuclear plant.

Matsubara, 57, became acquainted with a farmer caring for more than 300 cattle on his land in the 20-kilometer no-entry zone set by the government. Residents in the zone were ordered to evacuate, but the farmer stayed on to look after his animals.

At that time, the government was seeking to destroy the cattle within the no-entry zone by obtaining their owners’ consent, saying animals that were heavily contaminated with radiation from the nuclear accident could not be sold at market.

But some farmers did not want to put their livestock down.

However, keeping them alive costs 200,000 yen ($2,000) a year in feed per head.

Matsubara became curious why the farmers continued to look after cattle that cannot be sold or bred, despite the heavy economic burden.

He soon began making weekly trips from Osaka to Fukushima to film the lives of the farmers, their cattle and the people around them.

After finishing his regular job in promotional events on Fridays, Matsubara would drive 11 hours to Fukushima and spend the weekend documenting the plight of the farmers before returning to Osaka by Monday morning.

He had 5 million yen saved for the documentary, his first feature film. When the money ran out, Matsubara held a crowdfunding campaign to complete it. Shooting wrapped up at the end of December.

About 350 hours of footage was edited into the 104-minute “Hibaku-ushi to Ikiru.”

The film documents the farmers and their supporters who are struggling to keep the cattle alive.

One couple in the film returns to their land in Okuma, a town that co-hosts the Fukushima plant, to care for their herd. They affectionately named each animal and said it would be unbearable to kill them. Their trips are financed using a bulk of the compensation they received for the nuclear accident.

A former assemblyman of Namie, a town near the plant, tends to his animals while asking himself why he used to support nuclear power.

The documentary also sheds light on scientists who are helping the farmers. The researchers believe that keeping track of the contaminated cattle will provide clues in unraveling how low-level radiation exposure impacts large mammals like humans.

Matsubara said the documentary tells the real story of what is going on with victims of the nuclear disaster.

“Not all the farmers featured in the documentary share the same opinion or stance,” Matsubara said. “I would like audiences to see the reality of people who cannot openly raise their voices to be heard.”

Takeshi Shiba, a documentary filmmaker who served as producer of this project, hopes the film will reach a wide audience.

“Matsubara broke his back in making this movie,” he said. “I hope that many people will learn what Fukushima people are thinking.” ”

Interim storage schedule set for contaminated soil — The Yomiuri Shimbun

” The Environment Ministry has compiled its first project schedule for the interim storage of soil and other matter contaminated by the 2011 disaster at the Fukushima No. 1 nuclear power plant, sources said.

The ministry estimates that by fiscal 2020, it will have acquired between 640 and 1,150 hectares of land, which could store 5 million to 12.5 million cubic meters of contaminated soil.

This is the first concrete schedule the government has created. It is expected to be presented to local government officials at a Sunday meeting in Fukushima Prefecture.

If things go as planned, the government would acquire 40 percent to 70 percent of the land expected to be needed, which could store from 20 percent to slightly over 50 percent of the contaminated soil. However, it is unclear whether things will proceed as planned.

There is currently estimated to be about 10 million cubic meters of contaminated soil in Fukushima Prefecture, which could eventually rise to 22 million cubic meters.

The national government wants to purchase about 1,600 hectares straddling the municipalities of Okuma and Futaba in the prefecture as an interim storage facility.

However, as of the end of February only 18.5 hectares, or about 1 percent of the land, had been acquired.

Still, about 960 of the 2,365 landowners have given approval for the government to conduct surveys to estimate compensation. A ministry official said, “The pace of purchases is expected to pick up.”

If between 100 and 460 hectares are acquired every year starting in fiscal 2016, the ministry’s estimate of 640 to 1,150 hectares would be reached by the end of fiscal 2020.

As land is acquired, more contaminated soil can be brought to the interim storage facility.

The ministry estimates that if 2 million to 6 million cubic meters are brought to the facility in fiscal 2020, that would bring the total amount to 5 million to 12.5 million cubic meters by the end of that fiscal year. ”

How is Fukushima’s cleanup going five years after its meltdown? Not so well. — The Washington Post; Fukushima cleanup may take up to 40 years, plant’s operator says — CNN

Seen from the road below, the Fukushima Daiichi nuclear power station looks much as it may have right after the catastrophic earthquake and tsunami that caused a triple meltdown here almost five years ago.

The No. 3 reactor building, which exploded in a hydrogen fireball during the disaster, remains a tangle of broken concrete and twisted metal. A smashed crane sits exactly where it was on March 11, 2011. To the side of the reactor units, a building that once housed boilers stands open to the shore, its rusted, warped tanks exposed.

The scene is a testament to the chaos that was unleashed when the tsunami engulfed these buildings, triggering the world’s worst nuclear disaster since the one at Chernobyl, in Ukraine, in 1986. Almost 16,000 people were killed along Japan’s northeastern coast in the tsunami, and 160,000 more lost their homes and livelihoods.

Tokyo Electric Power Co. (Tepco), the utility company that runs the Fukushima plant and drew fierce criticism for its handling of the disaster, says the situation has improved greatly.

“In the last five years, radiation levels have been reduced substantially, and we can say that the plant is stable now,” said Akira Ono, the Tepco plant superintendent.

Efforts to contain the contamination have progressed, according to Tepco, including the completion Tuesday of a subterranean “ice wall” around the plant that, once operational, is meant to freeze the ground and stop leakage. Moves to decommission the plant — a process that could take 30 or 40 years, Ono estimated — are getting underway.

People will be allowed to return to their homes in the nearby town of Naraha next month and to Tomioka, even closer to the plant, next year. For now, Tomioka and neighboring Okuma remain ghost towns, lined with convenience stores, fast-food restaurants and gambling parlors that haven’t had a customer in five years. Bicycles lean near front doors, and flowerpots sit empty on windowsills.

A sign on the road to the plant showed a radiation reading of 3.37 microsieverts per hour, at the upper end of safe. At a viewing spot overlooking the reactor buildings, it shot past 200, a level at which prolonged exposure could be dangerous. Both readings are hundreds of times lower than they were a couple of years ago.

After about 20 minutes at the viewing spot, a Tepco official bustled visiting reporters, wearing protective suits, onto a bus. “We don’t want you out here too long,” he said. Below, men continued working on the site.

But one huge question remains: What is to be done with all the radioactive material?

There’s the groundwater that is flowing into the reactor buildings, where it becomes contaminated. It has been treated — Tepco says it can remove 62 nuclides from the water, including strontium, which can burrow into bones and irradiate tissue. It cannot filter out tritium, a radioactive isotope of hydrogen that can be used to make nuclear bombs but is not considered especially harmful to humans.

The water initially was stored in huge bolted tanks in the aftermath of the disaster, but the tanks have leaked highly contaminated radioactive water into the sea on an alarming number of occasions.

Now Tepco is building more-secure welded tanks to hold the water, theoretically for up to 20 years. There are now about 1,000 tanks holding 750,000 tons of contaminated water, with space for 100,000 tons more. The company says it hopes to increase capacity to 950,000 tons within a year or two, as well as halve the amount of water that needs to be stored from the current 300 tons per day.

As part of those efforts, Tepco built the 1,500-yard-long ice wall around the four reactor buildings to freeze the soil and keep groundwater from getting in and becoming radioactive. Company officials hoped to have the wall working next month; on Wednesday, however, Japan’s nuclear watchdog blocked the plan, saying the risk of leakage was still too high.

The options for getting rid of the contaminated water include trying to remove the tritium from it before letting it run into the sea; evaporating it, as was done at Three Mile Island, the Pennsylvania plant that melted down in 1979; and injecting it deep into the ground, using technology similar to that used to extract shale gas. A government task force is considering which option to choose. ”

CNN:

” Tokyo (CNN) — Cleaning up Japan’s Fukushima Daiichi nuclear plant, which suffered catastrophic meltdowns after an earthquake and tsunami hit in 2011, may take up to 40 years.

The crippled nuclear reactor is now stable but the decommissioning process is making slow progress, says the plant’s operator Tokyo Electric Power Co, better known as TEPCO.

“If I may put this in terms of mountain climbing, we’ve just passed the first station on a mountain of 10 stations,” said Akira Ono, head of the Fukushima plant.

It’s almost five years since the earthquake and the tsunami it triggered killed more than 15,000 people and destroyed coastal towns on March 11, 2011.

TEPCO has attracted fierce criticism for its handling of the disaster.

Biggest challenge

The biggest obstacle to closing down the plant permanently is removing all the melted nuclear fuel debris from three reactors, Ono told reporters after a press tour of the plant this week.

But TEPCO says it is in the dark about the current state of the debris.

Hydrogen gas explosions and nuclear meltdowns released lethal levels of radiation in 2011.

Though radiation levels have fallen, they still prevent workers from accessing the reactor buildings, making it hard to survey the condition of the destroyed facilities and molten fuel debris.

What to do with the large volume of contaminated water now stored at the plant is another problem.

Around 300 to 400 tons of contaminated water is generated every day as groundwater flows into the plant filled with radioactive debris.

To contain the tainted water, TEPCO pumps up the water and stores it in tanks, adding a new tank every three to four days. There are 1,000 tanks today containing 750,000 tons of contaminated water.

However, decontamination elsewhere on the premises is making headway. Workers now only need dust masks for a large part of the plant.

For outsiders, this appears to be only small progress. But it makes a huge difference for workers who used to wear full masks for outside clean-up and construction work.

Last year in October, Japan confirmed the first case of cancer in a Fukushima worker.

While agreeing to cover the worker’s treatment costs, the government stopped short of recognizing the scientific link between the cancer and his work. “
