Fate of Fukushima reactor cleanup uncertain after 11 years
March 13, 2022
OKUMA, Japan—Eleven years after the Fukushima Daiichi nuclear power plant was ravaged by a meltdown following a massive earthquake and tsunami, the plant now looks like a sprawling construction site. Most of the radioactive debris blasted by the hydrogen explosions has been cleared and the torn buildings have been fixed.
During a recent visit by journalists from The Associated Press to see firsthand the cleanup of one of the world’s worst nuclear meltdowns, helmeted men wore regular work clothes and surgical masks, instead of previously required hazmat coveralls and full-face masks, as they dug near a recently reinforced oceanside seawall.
Workers were preparing for the planned construction of an Olympic pool-sized shaft for use in a highly controversial plan set to begin in the spring of 2023 to gradually get rid of treated radioactive water—now exceeding 1.3 million tons stored in 1,000 tanks—so officials can make room for other facilities needed for the plant‘s decommissioning.
Despite the progress, massive amounts of radioactive melted fuel remain inside of the reactors. There‘s worry about the fuel because so much about its condition is still unknown, even to officials in charge of the cleanup.
Nearly 900 tons of melted nuclear fuel remain inside the three damaged reactors, and its removal is an unprecedented challenge involving 10 times the amount of damaged fuel removed in the Three Mile Island cleanup following its 1979 partial core melt.
The government has set a decommissioning roadmap aiming for completion in 29 years.
The challenge of removing melted fuel from the reactors is so daunting that some experts now say that setting a completion target is impossible, especially as officials still don‘t have any idea about where to store the waste.
Nuclear Regulation Authority Chairman Toyoshi Fuketa said recently that extra time would be needed to determine where and how the highly radioactive waste removed from the reactors should be stored.
Japan has no final storage plans even for the highly radioactive waste that comes out of normal reactors.
Twenty-four of the country‘s 60 reactors are designated for decommissioning, mostly because of the high cost needed to meet safety standards set up in the wake of the Fukushima disaster.
On March 11, 2011, a magnitude 9.0 earthquake caused a tsunami 17 meters (56 feet) high that slammed into the coastal plant, destroying its power supply and cooling systems, causing reactors No. 1, 2 and 3 to melt and spewing massive amounts of radiation.
Three other reactors were offline and survived, though a fourth building suffered hydrogen explosions.
The spreading radiation caused some 160,000 residents to evacuate. Parts of the surrounding neighborhood are still uninhabitable.
The melted cores in Units 1, 2 and 3 largely fell to the bottom of their primary containment vessels, together with control rods and other equipment, some possibly penetrating or mixing with the concrete foundation, making the cleanup extremely difficult.
Probes of the melted fuel must rely on remote-controlled robots carrying equipment such as cameras and dosimeters—which measure radiation—because radiation levels in those areas are still fatally high for humans.
In February, a remote-operated submersible robot entered the Unit 1 primary containment vessel, its first internal probe since a failed 2017 attempt. It captured limited images of what are believed to be mounds of melted fuel rising from the concrete floor.
Probes have moved ahead at Unit 2, where Tokyo Electric Power Co. (Tepco) plans to send in an extendable robotic arm later this year to collect melted fuel samples.
Tepco Chief Decommissioning Officer Akira Ono said in a recent online interview that robotic probes at Unit 1 and 2 this year are a major “step forward” in the decades-long cleanup.
Fukushima Workers Tell The Harrowing Story Of How They Tamed One Of The World’s Worst Nuclear Disasters
When the Fukushima Daiichi Nuclear Power Plant overheated in March 2011, these heroic workers stepped in. To this day, most people are unaware of their achievements.
03/12/2022
This story, by Fukushima Central Television, Co., Ltd., was published in partnership with HuffPost Japan and is translated from the original Japanese footage.
In 2011, three nuclear reactors melted down, provoking a series of hydrogen explosions and resulting in the world’s most severe nuclear accident. It happened in Japan, which had been long celebrated as a technology powerhouse.
At the time of the accident, the site became a veritable death trap, with extremely high levels of radioactivity and chunks of concrete from the explosion raining down on workers. And yet, there were some who remained on the ground to try and bring the overheating nuclear power plant to a halt.
“I just couldn’t run away when my country was about to sink,” one of the workers said. If this story can be told at all, it is precisely thanks to those who faced one of the world’s worst nuclear disasters out of a sense of pride in their country’s technology, attachment to the community and loyalty to their jobs.
The magnitude 9 Great East Japan Earthquake struck at 2:46 p.m. local time on March 11, 2011. Soon after, a large tsunami hit the ground level of the Fukushima Daiichi Nuclear Power Plant, which consisted of six nuclear reactors.
Satoru Umematsu, a veteran electrical engineer who had taken part in building the ground floor, was there when it happened. Umematsu was 60 at the time, and fast approaching retirement age.
When the nuclear power plant’s power transmission tower was knocked down by the force of the earthquake, causing the loss of external power supply, emergency generators kicked in, ensuring that cooling pumps could continue to function.
When the tsunami struck, however, the emergency generators of reactors 1 through 4, located about 33 feet (10 meters) above sea level, were flooded and stopped working.
When Umematsu rushed to the plant’s earthquake-proof building, about 115 feet (35 meters) above sea level, where the emergency response room was set up, it was packed with people. Inside, ashen-faced power plant executives were bustling around in a frenzy.
A Strategy Forms
As Umematsu and the others realized that the reactors could no longer be cooled down, they moved to secure a vehicle-mounted generator and power cables in order to generate electricity and restore the power supply.
“It was unimaginable that a nuclear power plant would lose all power. So, when it did actually happen, we were overcome by a tremendous sense of urgency,” he said.
For Umematsu, who had experienced all kinds of situations at different job sites in the course of his career, this crisis was an absolute first.
After graduating from junior high school and acquiring engineering skills at a vocational training center, Umematsu had accumulated over 40 years of experience in electrical construction sites, including power generation dams and nuclear power plants. He was familiar with most electrical systems in nuclear power plants. He was proud of the technological capabilities Japan had acquired after World War II and would proudly tell his relatives of his work at the nuclear power plant. He was relied upon by subordinates and colleagues, who respectfully referred to him as “Ume-san.”
In order to complete their task in the shortest possible time, Umematsu and his crew devised a simple strategy. To restore the power supply, they would park the vehicle-mounted generator next to the reactor building and link it to the nuclear power plant by connecting the power cables.
Opening A Path For The Truck-Mounted Generator
However, even the task of moving the truck-mounted generator closer to the reactor building was a daunting one. All kinds of debris and rubble brought by the tsunami littered the area around the reactor building, obstructing the passage of vehicles.
It wasn’t the power plant staff, the Self-Defense Forces, the fire department, nor the police who tackled this problem — it was a local resident.
Yoshishige Tochimoto was the managing director of a local company with about 10 employees. He was 51 at the time. When the earthquake struck, he witnessed the destruction of the nuclear power plant’s critical equipment.
“When the power transmission tower on the slope was brought down by the earthquake, it generated huge sparks. They were pink in color. Between 10 to 20 meters in length,” he said.
Tochimoto was on the premises as a subcontractor, doing seismic retrofitting work on the nuclear power plant. As he felt the ground shaking, he said he was unable to stand on his feet.
His own car was washed away by the tsunami that followed the earthquake. Luckily, his company’s excavator had suffered virtually no damage and only the caterpillar tracks had been submerged.
Wary of being exposed to radiation, Tochimoto had not actively sought out nuclear-related work in the past. But now he accidentally found himself on the scene of a nuclear disaster.
“This could be really bad, I thought,” he said.
‘I Won’t Be Gone For Long’
Workers from Tochimoto’s business and other local companies assembled in the parking lot in front of the earthquake-proof building.
They took a roll call to ensure everyone was safe. Then, the prime contractor company instructed them to “disband,” as it was feared that some of the workers would have lost some family members, or their homes would have been damaged. Tochimoto remembered what the other workers were talking about at the time.
“There was talk of opening a vent hole to prevent a hydrogen explosion,” he said.
A hydrogen explosion. He was unfamiliar with that word. The matter, however, seemed completely unrelated to him.
Worried about his wife and children, he decided to go back to his home, approximately 8 miles (13 kilometers) away. Since his car at the nuclear power plant had been washed away by the tsunami, he asked an acquaintance for a ride home.
What would normally be a 30-minute ride ended up taking them two hours, as the road was heavily congested with people evacuating. After getting home and making sure that everyone in his family was safe, he got a call from the prime contractor company.
“Will you help us fix the nuclear power plant?”
The roads inside the nuclear power plant were impassable by vehicles as they were covered in rubble and fissures in the asphalt had caused uneven gaps. Tochimoto thought that, if it was only a matter of fixing the road, it would not take long and he would be back home soon.
“I won’t be gone for long,” he told his family as he headed toward the Daiichi power plant. The time was around 7:30 pm.
Restoring Power, Fighting Against Fear
It took until nighttime to prepare the equipment needed to restore power. With preparations over, Umematsu gathered some young workers from the power plant and explained to them how to handle the power cables and how to route them.
The cables in question were special high-voltage cables called “Triplex,” which could suffer damage if dragged over the ground. The workers would have to connect the heavy cables, each 1-meter section weighing about 13 pounds (6 kilograms), from the truck-mounted generator parked outside the building to the power panel inside. Due to the building’s complex structure, they would have to lay the cable over a distance of about 130 meters. Many of the team’s members had no previous experience in handling that kind of equipment.
“As graduates of Japan’s most prestigious universities, they knew the theory, but had never actually connected a high-voltage cable. I was the only one who could tell them how to go about it.”

However, at around 11:00 p.m., radiation levels several tens of times higher than usual were detected inside the building of the Unit 1 reactor. The pressure on the steel “containment vessel” enclosing the reactor holding the nuclear fuel was about to exceed the permissible values. The director of the power plant immediately forbade anyone from entering the Unit 1 building. The signs were unmistakable that the feared meltdown had begun.
If the workers did not complete the operation swiftly, they too could have been exposed to lethal doses of radiation. If only the power supply could be restored, the looming crisis could be averted. It was up to Umematsu to make it possible.
“I’m pretty sure we were all scared. Extremely scared,” he said. “But being scared is different from being hesitant. Some were actually hesitant and did not want to go. We were certainly scared. Incredibly scared. After all, we were going to an unknown site. However, while being scared, we behaved normally.”
Since Umematsu was not a regular power plant employee, normally he would have been advised to go home. Instead, the power plant managers, relying on his skills, asked him to stay. Umematsu could have walked away while he still did not know how much radiation he would be exposed to. Instead, he chose to listen to his heart.
“I knew my skills were about to be put to the test,” he said. “I was glad my know-how could be of help in such a situation. When your country is as likely to stay afloat as it is to sink, you can’t quit just because you’re scared or because radiation levels are high.”
At that point, he still hadn’t been able to contact his wife and children. Nonetheless, as an engineer, he decided to throw himself into the task and went to work near the reactor building.
An Unsung Achievement
The truck-mounted generator, however, was still a long way away from being able to approach the reactor building. The road had yet to be repaired in order to make that possible. Fissures in the road caused height differences as much as a meter high. Tochimoto’s team studied the situation and considered what to do.
A proposal was made to bring in gravel from a nearby quarry to fill in the gaps, but was abandoned because it would have taken too long. Tochimoto thought that, as long as vehicles could pass, anything would do.
When he tried to turn the key to his company’s excavator, the engine came to life. Using the tip of the excavator’s bucket, he began to strip the asphalt coating in the parts of the road where the gaps were. He then proceeded to remove the gravel from under the paved surface and to press the surface down so as to create a gently sloping incline, at which point it looked as if a car might just be able to go through.
“While I was trying to open a road with the excavator, most of the people were actually watching me,” he said.
It seems that it was only thanks to Tochimoto and his excavator that the road was fixed. In just three hours, working by himself, he managed to repair the road inside the nuclear power plant so that vehicles could reach the reactor building.
Had Tochimoto not been there, it wouldn’t have been possible for the truck-mounted generator to approach the building to restore power, nor for fire engines to reach the same building and try to cool down the reactor.
To this day, most people are unaware of his achievement.
Because the road was fixed quickly, vehicles were able to reach the area around the reactor building by midnight. In the following hours, Tochimoto joined forces with workers from other companies to remove the rubble scattered around the reactor building.
A week after the accident, when a Hyper Rescue Team from the Tokyo Fire Department entered the area to cool off the fuel, one of its leaders said: “We were utterly surprised to see how the area surrounding the power plant had been cleared of debris to the point that not a single stone was visible, and our vehicles were able to approach without a hitch.”
The Real Risky Work Begins
Around midnight, a movable generator and a truck loaded with high-voltage cables smashed the nuclear protection gate and headed toward the reactor building.
Directing operations was Umematsu, the veteran engineer. He was hoping that, by connecting the movable generator to the power supply point near the Unit 1 reactor building, power could be restored, and the cooling pumps could start functioning once again.
The power cable was laid out near the reactor building, where radiation levels kept rising. The riskiest part of the work was about to begin.
Their efforts, however, had to be repeatedly interrupted as magnitude 4 and 5 aftershocks followed one after another. After a tsunami of such enormity, it was only natural that the area would have to be evacuated every time a tremor hit. Umematsu was getting impatient.
“We could have restored the power supply in five or six hours. However, we had to stop working and leave every time an aftershock struck, so things hardly moved at all. We went at it all night long, but most of the time we were sitting on our hands,” he said.
Radiation Levels 30,000 Times Higher Than Normal
A few hours have passed. At a press conference at 3 a.m. on March 12, Yukio Edano, chief cabinet secretary at the time, announced that he instructed workers to open a vent to release the pressure accumulated inside the Unit 1 reactor. Unless internal pressure is lowered in the reactor, he explained, the entire steel pressure vessel enclosing the nuclear fuel will explode. If that were to happen, huge amounts of radioactive material would be scattered across the surrounding area.
However, opening the required valve to ventilate the reactor building was an extremely difficult operation. The power plant operators assembled a “suicide squad” that rushed to where the valve was located, but radiation levels were so high that they had to turn back.
Around 6 a.m., just outside the building, Umematsu’s crew began full-scale operations to connect the power cable. Umematsu used a phone to report on progress to the emergency response office. As reception was poor, he kept moving around looking for a place where it would be easier to talk.
Without realizing it, he ended up nearby the exhaust tower through which steam exited the vent. At exactly the same time, efforts to open the valve from the outside finally succeeded.
Steam containing huge amounts of radioactive particles instantly rushed out of the exhaust tower, thoroughly irradiating Umematsu. “When I was near the exhaust tower, the dosimeter, which had been unresponsive for a while, suddenly came back to life with a loud BEEEEP. While cursing my luck, I had no choice but to continue working,” he said.
Japanese law sets maximum exposure levels for the general public at less than 1 millisievert per year (approximately 0.0027 millisieverts per day). Umematsu, on the other hand, was exposed to over 80 millisieverts in just one day.
Just As The Cable Was Connected …
The release vent is believed to have been successfully opened around 2:30 p.m. on March 12. Immediately after, efforts to connect the power cables, which had continued throughout the night, came to a successful completion.
It was now simply a matter of turning on the movable generator to restore power. Umematsu’s crew, in order to exchange places with the group that would operate the movable generator, had to leave the area and temporarily adjourn to the emergency response office in the earthquake-proof building.
“I believe it’s the same in power plants everywhere. Before moving on to the next job, you must let everyone know and get permission. You can’t proceed solely on your own judgment,” he said. “I would always let machine operators know that I finished this task, that I performed that check, and so on, then I would clear things with my superior, and only then would I proceed to the next task.”
It all happened exactly at moment Umematsu and his crew arrived at the emergency response office.
“It wasn’t a ‘whump,’ or a ‘thud,’ it was more like a popping sound,” he said.
At 3:36 p.m. on March 12, a hydrogen explosion shook the Unit 1 reactor.
For an unknown reason, the hydrogen that had filled the reactor building suddenly caught on fire and exploded. Concrete chunks from the gutted building flew across the entire area of the nuclear reactor at tremendous speeds.
“Find an empty car!”
Umematsu was shouting at the nearby workers at the top of his lungs. Radioactive rubble and insulation material was falling from the sky. He sensed that he would be exposed to considerable amounts of radiation just by touching it.
A fire engine happened to be parked nearby. The workers squeezed into the front and back seats one after another. Over 10 people crammed into a space normally meant for six. They kept the door closed for about 10 minutes. Holding their breath, they waited for the pollutants to pass by.
“‘There’s no going back now. The unthinkable has happened,’ I thought to myself. At that point I felt courage sweep over me. If you are on the scene of a Chernobyl-like disaster, it makes no difference anymore whether you’re inside or outside the reactor,” Umematsu said.
The hydrogen explosion shredded the power cables.
The surrounding area was once again littered with rubble. The repair work being carried out at reactors 2 and 3 had to start anew, which led to the following crisis.
The hydrogen explosion in the Unit 1 reactor could have been averted if only power could have been immediately supplied through the cable Umematsu’s crew had connected … The future could have been different. The expression on Umematsu’s face as his thoughts wandered back to those days, betrayed a deep anguish.
“Back then, if someone could have been with me at the site to issue instructions, if someone had said to me, ‘Leave things with me here and get ready to run power through the cables the instant they are connected,’ we could have done it,” he said.
“I immensely regret that we all went up to the office, even though the cables had been connected and we were ready to go. Looking back now, I feel we may have been too complacent,” he said.
Umematsu continued to work to connect the power supply into the following day, but from March 14, his radiation exposure had been so high that he was no longer allowed to work on-site. On the 15th, he had to evacuate the area and move outside of the nuclear power plant site.
It was then that, for the first time since the earthquake, he was finally able to talk on the phone to his eldest son.
Umematsu said: “We’re really in a dire situation, but we’re not panicking yet, so don’t worry!”
One week later, Umematsu returned to the Daiichi power plant.
While he was not allowed to work on-site, he could still help out by preparing food and drinks for those working on-site in a contaminated environment.
“If it hadn’t been for them, the emergency wouldn’t be over, you know.”
Stronger Than Fear, An Obligation To Help
At the time of the Unit 1 reactor explosion, Tochimoto, who had been working on repairing the road and removing rubble, was taking a break in the earthquake-proof building.
“‘What the hell is this!’ I thought. It came as a huge shock,” he said.
He waited for a few minutes and when he went outside, concrete and heat-insulating materials were scattered everywhere. Realizing that unless the area was again cleared of debris, vehicles wouldn’t be able to pass, he resumed working next to the reactor building.
“There was definitely radioactivity in the air, but I hadn’t been given a dosimeter so I had no way to tell,” he said.
Around him, some workers were scared of going to the work area, fearing that another explosion might follow. After all, who wouldn’t be afraid of working at a site rife with radiation as chunks of concrete rained down?
As for Tochimoto, however, another thought had begun to take hold in him. “Stronger than fear was the awareness that I had to do something about it. I felt I had to do everything in my power to help with the situation, even more so since I was a local,” he said.
Tochimoto was born and raised in Fukushima’s Futaba district, where the Daiichi power plant is located. Up until the time the nuclear power plant was built, the area was jokingly referred to as “the Fukushima boondocks,” because of how poor it was.
During the off-season for farmers, Tochimoto’s father would go look for work in big cities like Tokyo. In order to make ends meet and put food on the table, that’s what a lot of families had to do. As his father would only come home once a month, and sometimes not even then, Tochimoto says they never really had time together as a family.
After years of working hard away from home, his father learned how to operate a dump truck and eventually established the family’s heavy machinery company.
In the following years, the building of the nuclear power plant brought jobs and employment to the area, and the Tochimotos had a family life for the first time. They lived a quiet life, and the sight of his father playing with his grandchildren brought a smile to Tochimoto’s face.
“After things calmed down, my dad used to play a lot with his grandchildren. He would give them rides on his machines and play in many different ways with them. They were so cute,” he said.
The daily lives of local families, the foundation for which had been laid by his father’s generation, had prospered and continued to this day. Tochimoto recounted that while he faced extreme danger at the plant, as a local man, these memories were very strong in his mind.
To Leave Or To Go Back To The Nuclear Power Plant?
Tochimoto was once again opening a road through the rubble so vehicles could pass through. Unaware of how radioactive the scattered debris really was, he worked in close proximity to them, removing them one by one with the excavator.
At some point, the power plant’s female employees tried to evacuate from the area by minibus.
“They were already in the bus, but they couldn’t find a driver. When they asked if anybody could drive them, everyone fell quiet. Knowing that someone had to volunteer, I told them I’d do it. I felt I had to help in any way I could,” he said.
Driving the evacuation bus meant he would have to drive it back to the nuclear power plant so that more people could be evacuated again. Those being evacuated, on the other hand, would not return to the plant. He got at the wheel of the bus carrying the evacuees and headed to a junior high school outside the nuclear power plant premises. The thought of joining the evacuees himself crossed Tochimoto’s mind.
But eventually he made his way back to the nuclear power plant.
“A part of me didn’t want to go back, but there were still people working at the nuclear power plant. I headed back to the Fukushima Daiichi Nuclear Power Plant while thinking all the time I really should be heading home,” he said.
A ‘Local Guy’ Fighting Alongside Special Forces
After returning to the nuclear power plant, Tochimoto, in addition to removing rubble, also took part in efforts to secure water to cool the reactor. They would go around the site in search of water accumulated in the facilities and transport it to the fire engine.
The system for directly cooling down the reactor was out of order at the time. They were therefore trying to cool it by connecting the fire hoses to pipes that would directly inject water into the reactor.
On March 14, the Ground Self-Defense Forces arrived at the site where Tochimoto was working. It was the Central Nuclear Biological Chemical Weapon Defense Unit, which was qualified to deal with chemical weapons, including radioactive materials.
After filling the water truck of the Self-Defense Forces with water from the pressure filter tank near the reactor building, six people, including Colonel Shinji Iwakuma, who led the unit, headed to the Unit 3 Reactor. Tochimoto and his crew were also busy pouring water from the same tank into a sprinkler truck.
“I heard a ‘BOOM!’ I looked up and I saw what resembled a mushroom cloud,” he said.
At 11:01 a.m. on March 14, a hydrogen explosion occurred in the Unit 3 reactor.
Once again, countless chunks of concrete fell down from the sky. The members of the Self-Defense Forces were directly below. Four out of six were seriously injured. One of them was bleeding and had to be urgently transported to a specialized medical center by helicopter due to the risk of internal radiation exposure. Tochimoto immediately jumped into a car and left the scene

Tochimoto’s crew, in spite of witnessing two hydrogen explosions, resumed their work of removing the scattered rubble shortly after.
“I was told they were having problems at the power plant, so I was asked to help out. I couldn’t just say no. I thought I had no choice but work together with them. We had to assume we could turn things around,” he said.
Radiation levels within the nuclear power plant suddenly soared, and on the night of the 14th, Tochimoto too was finally ordered to evacuate. “Take it from here,” he said to the power plant staff, handing them the excavator’s key.
In spite of never having been closely associated with the nuclear power plant, he fought at the risk of his life until the very the last minute.
Like Umematsu, Tochimoto would later return to the Daiichi power plant. During the two weeks he was away, he learned how to remotely operate a concrete pump for injecting water into the reactor’s spent fuel pool and remained at the forefront of the efforts to resolve the emergency.
Eleven Years Later, ‘One Step At A Time, I Think Progress Is Being Made’
Following the successive meltdowns and hydrogen explosions, during a brief period of comparative calm, a system for cooling the reactor and the nuclear power plant began to be put in place. While Umematsu and Tochimoto were away, the Self-Defense Forces, the National Police Agency, the Tokyo Fire Department and the power plant’s own response team entered the site and began to work to restore power.
Thanks to them, it was finally possible to bring the overheating nuclear power plant to a halt at the last minute.
The worst-case scenario envisioned by the Japanese government, in which half of Japan would be destroyed and Tokyo itself would become uninhabitable, was thus averted by efforts on all sides.
The power plan at the center of this disaster continues to pose great risks. The nuclear fuel debris resulting from the meltdowns remains underground inside the plant. It is estimated to total about 880 tons and it continues to emit lethal doses of radiation, making it impossible for workers to approach it.
The Japanese government has joined forces with the power plant and Japanese companies like Toshiba, Hitachi and many others to tackle the removal of the debris, a difficult project and the world’s first of this kind. The only way to remove the debris is by remotely operated robots.
Eleven years after the accident, veteran engineer Umematsu returned to the site for an inspection.
He wanted to see once again the scene of the nuclear accident that had shattered Japan’s pride in the technological capabilities that had supported its postwar reconstruction, and which may still yield the opportunity for regaining that pride.
Robots small enough to navigate even the narrowest spaces inside this highly radioactive area were removing the rubble from inside the nuclear power plant piece by piece, while sending back images. All the workers operating the robots were young and are allowed to work only after months of training and simulations.
“Even a single piece of rubble is highly radioactive and dangerous. Even the smallest mistake can cause a huge accident, so we cannot afford to make any mistakes,” an engineer said.
Umematsu stared in silence at the young engineer who had said these words. And standing, for the first time since that day, at the site where he had supervised efforts to restore power, he said: “I really think we gave our very best at that time, and yet we didn’t succeed. Power was not restored. But I don’t think it was all in vain.”
“Oftentimes you must suffer multiple failures in order to attain a single result,” he added. “That’s how you move forward. From the perspective of removing the nuclear debris, I think advances are almost insignificant. And yet, one step at a time, I think progress is being made.”
Even though 11 years have passed since the accident, the removal of fuel debris has yet to start. Nonetheless, Umematsu thinks that “nothing is ever in vain.” And the simple fact that he can say these words is proof that the biggest problems have been overcome.

11 years later, Fukushima still faces a long road to full recovery
March 11, 2022
Eleven years after a broad swath of the northeastern Tohoku region was devastated by the Great East Japan Earthquake and tsunami, the government is stressing the progress made in the recovery and reconstruction of disaster-hit areas.
It points out, for example, that its plan to relocate 18,000 houses to areas of high ground for residential land development has been achieved. It also says 98 percent of the local seafood processing facilities have resumed operations in an encouraging sign of recovery of one of the mainstay industries in the region.
But the actual picture is less sunny with the process of recovery and reconstruction only halfway through for most local industries and people’s livelihoods. Local fish hauls are still around 70-80 percent of the pre-disaster levels in Miyagi and Iwate prefectures.
A survey by the Tohoku Bureau of Economy, Trade and Industry found that about 45 percent of affected companies have yet to return to the staffing levels before that day 11 years ago.
DISTRUST OVER FUKUSHIMA CONTAMINATED WATER
In particular, Fukushima Prefecture, where the catastrophic accident broke out at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear power plant, is struggling to recover what it lost in the disaster.
Coastal fishing catches last year were only 20 percent of pre-disaster figures. Fukushima’s hardships will be further compounded by the scheduled start in spring next year of TEPCO’s plans to release treated radioactive water from the crippled nuclear plant into the Pacific Ocean.
Underground water that keeps flowing into the melted reactors is generating a steadily increasing volume of “treated water,” or water currently stored in tanks installed within the compound after being treated with special equipment to eliminate most of the highly radioactive materials.
The government emphasizes that it decided to discharge the water into the sea after explaining meticulously to local communities that scientifically the water poses no health hazard. But the fisheries associations in both Miyagi and Ibaraki prefectures as well as in Fukushima have voiced opposition to the step.
“The decision was made in Tokyo and has been imposed on us,” fumes Ayanori Sato, 31, a Sakhalin surf clam fisherman in the Yotsukura district of Iwaki, a city in Fukushima Prefecture.
In Yotsukura, local fishermen restarted Sakhalin surf clam fishing three years after the nuclear disaster. Since four years ago, the district has been holding Sakhalin surf clam festivals once or twice a month as part of its efforts to dispel unfounded negative rumors about the safety of locally caught clams.
The government and TEPCO have pledged to provide proper compensation if the release of treated water breeds rumors that damage local industries.
A recent Supreme Court ruling on a damages lawsuit filed by people forced to evacuate from their homes due to the Fukushima disaster has increased the distrust of the government and the utility among victims.
The ruling confirmed that the compensation standards set by the government’s interim guidelines are not sufficient. For Sato, who thinks of fishing as his lifelong job, money is not enough to compensate for what he has lost.
The release of treated water is expected to continue for 30 years or so. The government and TEPCO should establish a system to monitor the effects on the environment and locally caught seafood during the period.
There can be no real progress on this matter unless the government and the utility actively disclose information to win the understanding of local communities.
NO PROSPECT FOR MANY EVACUEES TO RETURN HOME
In Fukushima Prefecture, there remains some 340 square kilometers of land where the evacuation order is still in place, areas near the crippled plant with high levels of radiation, known as “kitaku konnan kuiki” (difficult-to-return zone).
The order is set to be lifted this spring in certain parts of the zone designated as reconstruction priority areas eligible for preferential policy support to help improve the living environment, such as intensive decontamination and infrastructure development efforts.
In the town of Futaba, home to the stricken plant and the only municipality in the prefecture that is still covered entirely by the evacuation order, local residents will be allowed to return home for the first time since the accident, possibly in June.
On March 4, a group of 12 workers, including TEPCO group company employees, were carrying 20 tatami mats, chests of drawers and other items placed on them out of the house of Kiyotaka Iwamoto, 74, located close to Futaba Station.
Although the household goods seemed to be still usable, they had to be replaced to lower the radiation levels in the room.
Iwamoto is hoping that the work to repair his home will be completed by summer. But he is expecting to have to shuttle between his home in Futaba and his evacuation site in the city of Nasushiobara in Tochigi Prefecture for the time being.
By the end of February, some 20 local households applied for permission to stay in special facilities within the town to prepare for returning to their homes.
There is no family preparing to return near Iwamoto’s home. He is also concerned about the fact that there is no facility within the town that offers rehabilitation programs for his 71-year-old wife, who suffered a subarachnoid hemorrhage after the disaster.
These reconstruction priority areas constitute only 8 percent of the difficult-to-return zone. The government has repeatedly said it will decontaminate the land and houses of local residents who want to return to their homes so that the order can be lifted for the entire zone by the end of the 2020s. But it has yet to offer any specific plan to achieve this goal, keeping the outlook uncertain.
Despite all these problems plaguing affected areas, the government has tried to paint a rosy picture of Fukushima’s future in its “Fukushima Innovation Coast Framework,” a policy initiative to nurture new high-tech industries in such areas as robotics and hydrogen energy.
Goals are important for efforts to rebuild disaster-hit areas. But promoting such an unrealistic dream does not lead to any progress in key goals. The first step in rebuilding ravaged communities in Fukushima should be mapping out down-to-earth visions for the future of the communities based on tough-minded assessments of the reality of Fukushima.
DEVELOP CONVINCING PLANS TO DECOMMISSION THE REACTORS
At the end of January, a robot arm designed to remove melted nuclear fuel debris at the bottoms of ruined reactors at the plant arrived in Fukushima. A trial run of the machine has started for use at the No. 2 reactor.
This is, however, only a small step in the long and complicated clean-up process. There are an estimated 880 tons of radioactive debris at the bottoms of the Nos. 1-3 reactors. Nobody knows, however, how the debris is scattered about and in what form.
The government has already dropped the goal of removing the debris in 20-25 years, included in the road map for decommissioning the reactors published in December 2011. But the goal of completing the decommissioning process in 30-40 years has been kept unchanged.
One big challenge is finding a location for the final disposal of contaminated soil and waste temporarily stored in Futaba and Okuma, where the plant is located. The completion of the work to deal with the consequences of the accident, which is far more difficult than the ordinary decommissioning process and requires different approaches, is vital for progress in the reconstruction of ravaged communities.
But the government has not offered any clear image of this future nor any reliable estimate of the total cost. While the government has estimated the total cost at 22 trillion yen ($189.15 billion), including the compensation to be paid to victims, one research institute has pegged it at 35 trillion to 80 trillion yen.
The government needs to lay out clear and concrete visions for the ultimate state of the Fukushima No. 1 plant and the process of achieving that state while subjecting the visions to Diet scrutiny. Without such visions, it will remain difficult to clear up the dark cloud of uncertainty hanging over Fukushima’s future.
It is, of course, impossible to find a quick solution to the challenge. The long road to Fukushima reconstruction is strewn with obstacles that have to be overcome one by one.
11 years on, Fukushima radioactive waste still tough challenge for Japan
TOKYO, March 11 (Xinhua) — Eleven years after the quake-induced Fukushima disaster, the aftermath of the nuclear meltdown, not least a large amount of contaminated water, remains a grave challenge for Japan as well as for the rest of the world.
On March 11, 2011, a magnitude-9.0 earthquake struck off the coast of Fukushima Prefecture in Japan. An earthquake-triggered tsunami engulfed the Fukushima Daiichi Nuclear Power Plant, causing core meltdowns in units one to three and leading to the worst nuclear crisis since Chernobyl.
Little progress has been made over the past year on the most pivotal and hardest work of decommissioning the Fukushima Daiichi power plant — how to remove the nuclear residue from the meltdown. Japan’s International Research Institute for Nuclear Decommissioning estimated that the total weight of nuclear waste mix from melted fuel rods and other materials in pressure vessels that melted during the accident could be 880 tons.
Since the end of 2011, No. 1 to No. 3 units have been in a stable state of low temperature cooling, but the internal radiation is still very high, making it difficult for personnel to work in close proximity. Relevant work has to rely on remote tools such as remotely controlled robots and mechanical arms, but not a single piece of nuclear residue has been removed so far. The Tokyo Electric Power Company (TEPCO) said it plans to first try to remove the nuclear residue from unit 2 this year.
Hiroaki Koide, a retired researcher at Kyoto University, said the Japanese government and TEPCO’s 30-40 year “roadmap” for decommissioning the reactors was an “illusion” that could not be achieved because it would be “impossible even in 100 years” to remove the large amount of scattered nuclear debris, which would have to be sealed in a “sarcophagus.”
In April last year, the Japanese government officially decided to discharge the nuclear contaminated water into the sea starting in the spring of 2023. The contaminated water at the Fukushima Daiichi Nuclear Power Plant contains radioactive cesium, strontium, tritium and other radioactive substances.
The Japanese government and TEPCO said the Advanced Liquid Processing System (ALPS), a multi-nuclide removal system, can remove 62 radioactive substances except tritium, which is difficult to remove from water.
Japanese fishing groups strongly oppose the plan to discharge contaminated water into the sea. Opposition parties, including the Constitutional Democratic Party of Japan, also criticized the Japanese government’s plan and demanded its withdrawal.
About 60 percent of the 42 mayors in the disaster-stricken Fukushima, Miyagi and Iwate prefectures opposed the decision. The Japan Federation of Bar Associations submitted a statement opposing the plan to Japanese Prime Minister Fumio Kishida and others, urging the government to consider other measures, such as mixing contaminated water with cement and sand.
At the invitation of Japan, an investigation team of the International Atomic Energy Agency (IAEA) visited Japan on Feb. 14-18 to complete its first field investigation.
Lydie Evrard, deputy director general of the IAEA, said Japan had studied several options for treating the contaminated water, but ultimately chose the option of discharging it into the sea, and the Japanese government invited the IAEA to conduct a safety review, hoping that the agency would give basic policy support to the treatment plan. What she pointed out was that it was up to the host country to decide how to deal with the contaminated water, and that the agency provides only technical assessments, not options.
China is seriously concerned about and firmly opposes Japan’s unilateral decision to discharge the nuclear-contaminated water into the sea and its proceeding with the preparatory work, Chinese Foreign Ministry Spokesperson Zhao Lijian has said.
He stressed that the handling of the nuclear-contaminated water from Fukushima is never Japan’s private matter. Instead, it bears on the marine environment and public health of the whole world.
Japan should heed and respond to the appeals of neighboring countries and the international community, and rescind the wrong decision of dumping the water into the sea. “It mustn’t wantonly start the ocean discharge before reaching consensus with stakeholders and relevant international institutions through full consultations,” Zhao said.

Bullying, suicide attempts…11 years for a girl in Fukushima… Before evacuation, she was cheerful: “It’s OK. You’ll just make more friends.”
March 11, 2022
Serialization “At the End of the Tunnel: Trajectory of the Girl and Her Family” (1)
On her last day of high school, a girl (18) nearly burst into tears when her name was called by her homeroom teacher at the presentation of her diploma. The teachers and friends at this school made me smile from the bottom of my heart. I was sad to graduate. I didn’t think so when I was in elementary and junior high school.
On March 11, 2011, just before the accident at TEPCO’s Fukushima Daiichi Nuclear Power Plant occurred, the girl was 7 years old and entering the second grade of elementary school. During the summer vacation after moving on to the next grade, she evacuated from Koriyama City in Fukushima Prefecture to Niigata. In the place where she sought a safe haven, she was bullied, saying “Fukushima is dirty” and “radioactive,” and cried out repeatedly that she wanted to go back to Fukushima. When she was in high school, she even attempted suicide.
Days went on in a long dark tunnel with no way out. Now, under a clear sky, I feel as if I have finally escaped from that exit. Whenever you feel lonely, come back to us. From April, she will attend a vocational school in Niigata Prefecture to fulfill her dream.
Classmates transferred one after another… “It’s my turn now,” she said.
March 11, 2011, 2:46 p.m. I was watching TV with my grandfather at home in Koriyama City. Furniture fell over and dishes broke as a result of the violent shaking. The cell phone was beeping incessantly with earthquake early warnings. I hit my head and body hard against the leg of the sunken kotatsu and the desk I was squatting on, and cried out in fear. I’m going to die, aren’t I? When she ran out of the house, she found a blizzard.
At the Fukushima Daiichi Nuclear Power Plant, hydrogen explosions occurred at the Unit 1 reactor on March 12 and at the Unit 3 reactor on March 14. A relative who had family members in the Self-Defense Forces told her father, “I heard the nuclear power plant is dangerous. We’re going to run away,” and her parents decided to evacuate temporarily.
In the early morning of the 16th, the car with the family of four, including her one-year-old sister, headed for Niigata. At the shelter where they took shelter, there was hot food and hot spring baths. A private room was prepared for the family’s young child, and the mother was small, saying, “Even though we are not from the evacuation zone. Every day was fun because I could play with other children who had evacuated.
When she returned to Koriyama in time for the new school term in April, she found her days suffocating. The children wore long sleeves, long pants, hats, and masks to avoid exposure to radiation, and the classroom windows were closed. The school building was covered with blue tarps, and the topsoil in the schoolyard had been stripped and piled up for decontamination. The homeroom teachers told us not to touch the soil.
In the middle of the first semester, one by one, her classmates moved away from the school. I think it’s dangerous here, so I’m thinking of going to Niigata. When my parents asked me about it, I thought, “My turn has come.
I was sad to leave my beloved father and grandparents who remained in Fukushima for work, but I knew that my parents were trying to protect me and my sister. So I thought positively and answered cheerfully. ‘That’s fine. You’ll just make more friends.”
At the closing ceremony of the first semester, I was filled with sadness when my friends told me, “It will be okay wherever you go,” and “I’ll be waiting for you to come back to Fukushima again. That day, we took a group photo in class. It is a treasure that I still look back on from time to time. (Natsuko Katayama)
Based on more than a year of interviews, this report tells the story of the girl and her family over the past 11 years in four installments.
Fukushima spill plan goes ahead despite local opposition
March 10, 2022
By Antonio Hermosin Gandul
Tokyo, March 10 (EFE).- Japanese authorities continued with their plan to dump contaminated and processed water from the Fukushima nuclear power plant into the Pacific Ocean in 2023, despite the rejection of local communities suffering the consequences of the nuclear disaster 11 years on.
The Fukushima Daiichi plant, damaged by the March 2011 earthquake and tsunami, faces an uncertain dismantling process that will last beyond 2050, and in which the growing accumulation of radioactive water is the most urgent problem due to sort out.
TEPCO, the plant operator, and the Japanese government approved in April a plan to pour thousands of tons of water into the Pacific Ocean from 2023 after being treated. It’s a measure supervised by the International Atomic Energy Agency that has generated strong opposition from local fishermen’s groups and environmental organizations.
Fukushima Daiichi faces a long list of unprecedented challenges in the history of nuclear energy, among which the removal of highly radioactive fuels from the reactors stands out, or the storage of these and other residues that represent a great risk to human health and the environment.
The most pressing of these headaches is what to do with the water contaminated with radioactive waste after it is used to cool reactors or leak into nuclear facilities, of which some 1.29 million cubic meters are accumulated in drums inside atomic facilities where space has run out.
After analyzing with a scientific panel a series of possible solutions of enormous technical complexity, including methods of evaporation or underground injection, authorities and TEPCO opted to dump all the water into the sea in front of the plant after decontaminating it.
The operator said the water will not represent any danger to human health or the environment, since its level of radioactivity will be “well below” the limits established by both Japan and the World Health Organization.
The water is subjected to a succession of filters that eliminate all radioactive materials considered dangerous with the exception of tritium, an isotope present in nature, although in low concentration.When diluted in seawater, this would generate ‘negligible’ levels of radiation, according to TEPCO and Japan’s government.

11 years on: Fukushima governor wants all evacuation orders to be lifted
Mar 11, 2022
Fukushima – The government should lift all evacuation orders issued after the March 2011 nuclear accident in Fukushima Prefecture, Gov. Masao Uchibori said in an interview.
Uchibori welcomed the central government’s pledge to ensure that all evacuees from the triple meltdown at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear plant may return home by the end of the decade, if they wish.
“However, there are many challenges such as handling land and housing of residents who do not intend to return, and working out details of decontamination methods,” Uchibori said Monday.
“The situation differs by area. We will urge the central government to carefully listen to the intentions of each municipality and act in a responsible way to lift evacuation orders in all difficult-to-return areas and reconstruct such zones,” he said.
When asked about the central government’s plan to release treated radioactive water from the nuclear plant into the ocean, he said that he will urge the government to carefully give explanations to all people concerned and to give out more information to prevent any more harmful rumors.
“There are opinions in Japan and abroad opposing the water release and calling for the careful handling of the matter,” he said.
On the handling of contaminated soil from Fukushima, Uchibori said that it is the central government’s obligation to move it out of the prefecture for final disposal by 2045.
On last summer’s Tokyo Olympics and Paralympics dubbed the “Reconstruction Games,” the governor said that the event became a legacy although there were some restrictions.
“Due to the COVID-19 pandemic, the event was different from what we had imagined, but the prefecture’s products, such as peaches, were highly evaluated by people related to the Games,” he said.
“By utilizing the connections we gained at the Games, we will work to expand exchanges through sports, such as by hosting large-scale events and having children and athletes interact with each other.”
“We also want to further share Fukushima’s attractiveness both domestically and internationally through exchanges,” he added.

11 years later, fate of Fukushima reactor cleanup uncertain
By Mari Yamaguchi, March 11, 2022
OKUMA, Japan — Eleven years after the Fukushima Daiichi nuclear power plant was ravaged by a meltdown following a massive earthquake and tsunami, the plant now looks like a sprawling construction site. Most of the radioactive debris blasted by the hydrogen explosions has been cleared and the torn buildings have been fixed.
During a recent visit by journalists from The Associated Press to see firsthand the cleanup of one of the world’s worst nuclear meltdowns, helmeted men wore regular work clothes and surgical masks, instead of previously required hazmat coveralls and full-face masks, as they dug near a recently reinforced oceanside seawall.
Workers were preparing for the planned construction of an Olympic pool-sized shaft for use in a highly controversial plan set to begin in the spring of 2023 to gradually get rid of treated radioactive water — now exceeding 1.3 million tons stored in 1,000 tanks — so officials can make room for other facilities needed for the plant’s decommissioning.
Despite the progress, massive amounts of radioactive melted fuel remain inside of the reactors. There’s worry about the fuel because so much about its condition is still unknown, even to officials in charge of the cleanup.
Nearly 900 tons of melted nuclear fuel remain inside the three damaged reactors, and its removal is an unprecedented challenge involving 10 times the amount of damaged fuel removed in the Three Mile Island cleanup following its 1979 partial core melt.
The government has set a decommissioning roadmap aiming for completion in 29 years.
The challenge of removing melted fuel from the reactors is so daunting that some experts now say that setting a completion target is impossible, especially as officials still don’t have any idea about where to store the waste.
Nuclear Regulation Authority Chairman Toyoshi Fuketa said recently that extra time would be needed to determine where and how the highly radioactive waste removed from the reactors should be stored.
Japan has no final storage plans even for the highly radioactive waste that comes out of normal reactors. Twenty-four of the country’s 60 reactors are designated for decommissioning, mostly because of the high cost needed to meet safety standards set up in the wake of the Fukushima disaster.
On March 11, 2011, a magnitude 9.0 earthquake caused a tsunami 17 meters (56 feet) high that slammed into the coastal plant, destroying its power supply and cooling systems, causing reactors No. 1, 2 and 3 to melt and spewing massive amounts of radiation. Three other reactors were offline and survived, though a fourth building suffered hydrogen explosions.
The spreading radiation caused some 160,000 residents to evacuate. Parts of the surrounding neighborhood are still uninhabitable.
The melted cores in Units 1, 2 and 3 largely fell to the bottom of their primary containment vessels, together with control rods and other equipment, some possibly penetrating or mixing with the concrete foundation, making the cleanup extremely difficult.
Probes of the melted fuel must rely on remote-controlled robots carrying equipment such as cameras and dosimeters — which measure radiation — because radiation levels in those areas are still fatally high for humans.
In February, a remote-operated submersible robot entered the Unit 1 primary containment vessel, its first internal probe since a failed 2017 attempt. It captured limited images of what are believed to be mounds of melted fuel rising from the concrete floor.
Probes have moved ahead at Unit 2, where TEPCO plans to send in an extendable robotic arm later this year to collect melted fuel samples.
TEPCO Chief Decommissioning Officer Akira Ono said in a recent online interview that robotic probes at Unit 1 and 2 this year are a major “step forward” in the decades-long cleanup.
“It’s like we have finally come to the starting line,” Ono said. “Before, we didn’t even know which way we were supposed to go.”
Ono said the Unit 2 melted fuel test removal will start from a granule or two, all of which will be sent for lab analysis, meaning a storage facility won’t be necessary until larger amounts are hauled out. Even a tiny amount would provide valuable data for research and development of fuel and debris removal technology for all three reactors, he said.
Hideyuki Ban, the co-founder of the Citizens’ Nuclear Information Center who previously served on government nuclear safety panels, proposes the underground burial of solidified treated water for stable long-term storage, while entombing the three reactors for several decades — like Chernobyl — and waiting for radioactivity to decrease for better safety and access for workers instead of rushing the cleanup.
Since the disaster, contaminated cooling water has constantly escaped from the damaged primary containment vessels into the reactor building basements, where it mixes with groundwater and rainwater that seep in.
The water is pumped up and treated, partly recycled as cooling water, with the remainder stored in 1,000 huge tanks crowding the plant. The tanks will be full at 1.37 million tons by next spring, TEPCO says.
The government has announced plans to release the water after treatment and dilution to well below the legally releasable levels through a planned undersea tunnel at a site about 1 kilometer offshore. The plan has faced fierce opposition from local residents, especially fishermen concerned about further damage to the area’s reputation.
TEPCO and government officials say tritium, which is not harmful in small amounts, is inseparable from the water, but all other 63 radioactive isotopes selected for treatment ‘can be reduced to safe levels’, tested and further diluted by seawater before release.
Scientists say the health impact from consuming tritium through the food chain could be greater than drinking it in water, and further studies are needed.
At one of the water treatment facilities where radiation levels are much higher, a team of workers in full protective gear handled a container filled with highly radioactive slurry. It had been filtered from the contaminated water that’s been continuously leaking from the damaged reactors and pumped up from their basements since the disaster. Large amounts of slurry and solid radioactive waste also accumulate in the plant.
Radiation levels have fallen significantly after decontamination since the disaster, and full protection gear is only needed in limited areas, including in and around the reactor buildings.
On a recent visit, AP journalists used cotton gloves, goggles, a head cover and surgical masks to tour low-radiation areas.
Additional protection, including hazmat coveralls and double rubber gloves, was required when the journalists entered the Unit 5 primary containment vessel and stood on the grating of the pedestal, a structure beneath the defueled core, where officials explained the concept of using robotic probes in No. 1 and 2 reactors.
TEPCO has emptied spent fuel from the No. 3 and No. 4 reactor pools, but removal at the No. 1 and 2 reactors has been delayed several years because of high radiation and contaminated debris, posing concerns of a spent fuel meltdown in case another major quake caused water loss and overheating.
Futaba Mayor Shiro Izawa says the Fukushima Daiichi plant must be safely and fully decommissioned “to make our hometown a safe and livable place again.” Izawa said he wants the government to “wipe out the (region’s) negative image” by tackling the safe cleanup, which is a prerequisite for the town’s reconstruction.
11 years after meltdown, Fukushima towns to welcome back residents
March 11, 2022
TOKYO — Eleven years after a major earthquake and tsunami triggered meltdowns at the Fukushima Daiichi nuclear plant, Japan will reopen part of the surrounding area to residents starting this spring as a new hub for the region’s revival.
The government considers the five years that began in April 2021 as the “second phase” of recovery efforts in northeastern Japan’s Fukushima Prefecture. But with costs ballooning and tens of thousands still unable to return home, rebuilding communities there remains an uphill battle.
The death toll from the triple disaster, which occurred March 11, 2011, totaled 15,900 as of the beginning of this month. The search for the 2,523 missing continues to this day.
Another 3,784 deaths are associated with the disaster. A total of 38,139 evacuees had not returned to their homes as of Feb. 8, including 26,692 from Fukushima who now live outside the prefecture.
As the next step in the region’s recovery, Japan is decontaminating a 27-sq.-km area that was evacuated following the disaster, including the towns of Futaba and Okuma. Evacuation directives will be lifted in aand allowing residents will be allowed to move back there starting this spring and into 2023. The government plans to press ahead with nurturing industries to help disaster-hit areas grow on their own.
Another 310 sq. km around the Fukushima plant will remain off-limits to the public. Japan plans to eventually decontaminate residential areas as needed to give all former residents the option to return by the end of the 2020s.
Tokyo Electric Power Co. Holdings, operator of the Fukushima plant, aims to start removing nuclear debris from the damaged reactors on an experimental basis in the latter half of the year. The utility looks to complete the decommissioning of the plant by 2041 to 2051.
But recovery efforts in Fukushima face mounting financial and logistical hurdles.
Contaminated soil and other waste from the disaster are supposed to be stored within the prefecture for 30 years before they can be moved elsewhere. But the government has yet to secure a final disposal site, and the total cost of the process remains unclear.
In terms of decontamination, “there’s no clear guideline on how far into the mountains and woods our efforts would extend,” said an official at the Environment Ministry.
Japan estimates the total costs associated with the Fukushima disaster, including damages paid to victims, at 22 trillion yen ($190 billion). But the final tally could end up far higher, given how much of the recovery process still needs to be ironed out. One private-sector estimate places the figure beyond 35 trillion yen.
“Should costs continue to mount, our budget for other energy-related policies, like promoting renewable sources, could take a hit,” a government source said.
Though the rebuilding of infrastructure is nearly complete in neighboring Miyagi and Iwate prefectures, personal connections within communities have weakened further, partly due to the COVID-19 pandemic. More than 680 people living alone have died in the three prefectures since the disaster. Japan still faces the issue of people becoming isolated, which was highlighted following the 1995 earthquake in the Kobe area.
3/11 Fukushima disaster evacuee has been ‘wandering’ for 11 years while growing vegetables
March 10, 2022
KUKI, Saitama — It will soon be 11 years since the Fukushima nuclear disaster was triggered by the Great East Japan Earthquake and tsunami. A woman who lived near the nuclear plant continues to live as an evacuee in Saitama Prefecture, saying, “I am still in temporary housing and wandering around with no place to return to.”
Hisae Unuma, who leads a displaced life in Kazo, Saitama Prefecture, works hard every day as a vegetable farmer, something she had no experience doing before the disaster.
The 68-year-old woman’s home was located in the Fukushima prefectural town of Futaba, 2.5 kilometers from Tokyo Electric Power Company Holdings Inc.’s Fukushima Daiichi Nuclear Power Station. She was a farmer who bred the Japanese Black cattle and grew rice. She was particular about the grass she used to feed the cattle, and recalled that the conception rate of her cows was “one of the top three in the county of Futaba.” The farmer believes that “land is the source of life,” and she had put compost in her rice paddies and also made efforts to grow delicious rice. All of this was lost in an instant.
After the disaster, Unuma evacuated to the city of Kazo, where the Futaba town hall was also temporarily moved. In order to “build up her strength for when she returns to Futaba,” she learned to grow vegetables from scratch and rented farmland to start growing them.
Unuma now delivers vegetables she grows to local schools for lunches and sells them at a market. Her husband, whom she shared her life with, passed away from cancer in 2017. People tell her, “We are waiting for your vegetables,” and that is a big support for her.
Her home in Futaba is located in a “difficult-to-return” zone with high radiation levels, and she is only allowed to return home on a temporary basis. When she visited in February, it looked as if her home would collapse at any moment.
“Even if I wanted to go back, I can’t. I am not young enough to want to go back,” Unuma said.
A message to all people in the world concerned about the fate of the people of Fukushima
Never in my life has a year seemed so severe as the one that followed, in 2021, the tenth anniversary of the Fukushima Dai-ichi nuclear accident: I had the constant sensation of being bitten by the icy cold of an ever-lasting winter. I must start by saying that last year I lost five very close friends one after the other. All of them lived in Fukushima and were in their fifties at the time of the accident. I can’t prove that their deaths are related to the nuclear accident, but I can’t help but thinking that they were. And many people around me share the same doubts.
Since last year, the Japanese government, the Fukushima Prefecture and the media have decided to more radically pursue their course. It’s no longer a question of dealing with the dramatic reality caused by the ongoing nuclear accident, but of preaching for the “reconstruction” of the Prefecture and acting only for its implementation. Despite the spread of Covid-19, the Tokyo Olympic Games was imposed in an incredibly authoritarian way. The Torch relay started from Fukushima, more precisely J-Village Stadium, a sports complex which was an important base for the workers in the aftermath of the nuclear accidents. In addition, in April 2021, the government endorsed a plan to discharge into the sea huge quantities of radioactive water accumulated at the Fukushima Dai-ichi plant site, despite the many voices in Japan itself, but also in other countries, which strongly protested this decision.
Yet, the most serious issue for me is the problems faced by the younger generation. The government, in order to replace the numerous evacuees who refuse to return to their commune of origin, allocated in 2021 a budget of 1.8 billion yen (13.9 million euros) to persuade newcomers to settle in the 12 municipalities formerly designated as mandatory evacuation zones after the accident. In concrete terms, a premium of 2 million yen (€ 15,500) will be granted to each household having recently moved into these 12 municipalities. In addition, at four kilometers from the crippled nuclear site, on the lawn of the Great East Japan Earthquake and Nuclear Disaster Memorial Museum, a local tourism company organizes various activities to attract high school and university students as well as young working adults: meals, stargazing nights, yoga classes etc. Finally, at an increasing pace, “discussion meetings” for young people are organized by the Ministry of the Environment and other organizations, on topics such as the release of radioactive water into the sea or the reuse of contaminated soil. All these appear to me as a staging to manipulate the minds of the young people. As for the “Supplementary reader on radiation”, distributed from 2011, after the accident, to all primary and junior high schools in Japan by the Ministry of Education, its latest version considerably reduces the paragraphs devoted to the dangers of radioactivity and the question of responsibilities of the nuclear accident. On the other hand, there are some pages in the appendix that praise the harmlessness of the radio-contaminated water accumulated at the Fukushima Dai-ichi Nuclear Power Plant.
On January 27 this year, six young people who were between 6 and 16 years old at the time of the accident, and who have been suffering from thyroid cancer, filed a lawsuit against TEPCO, the operator of Fukushima Dai-ichi. They demand that the causal link between the nuclear accident and the triggering of their thyroid cancer be investigated. Indeed, the Prefectural Oversight Committee for Fukushima Health Management Survey in charge of evaluating the prefectural health survey still refuses to recognize any cause-and-effect relationship between these two factors. The young plaintiffs hope that this causality, if recognized at the end of the trial, will lead to the establishment of a system of aid for all other post-accident thyroid cancer patients, who are experiencing the same suffering as they are. This would cast a small glimmer of hope on their future. The consequences of the accident are made less and less visible. At the same time, the “reconstruction” of Fukushima (repopulating the evacuation areas, creating high-tech industrial zones, managing experimental agricultural sites to grow edible crops, etc.) is pushed forward at all costs. In this context, it must have taken extraordinary courage for these young people to file such a lawsuit. I call on all adults to support them in every way possible.
As a Fukushima resident and victim of the nuclear accident, I was deeply shocked by the European Commission’s proposal earlier this year to include nuclear energy in the green taxonomy. Nuclear reactors, no matter how small they become or how peaceful their use is claimed to be, use the same technology developed to create the atomic bomb. And throughout all the stages, nuclear energy production leads to the exposure of workers and local residents to radioactivity. Privilege the conquest of great power without hesitating to sacrifice small people – this is, in my opinion, the state of mind that still governs the nuclear industry today. Moreover, humanity has not totally mastered safety and security in this domain, and is also unable to find a solution to the perennial problem of disposal of the toxic waste. Finally, it is clear that nuclear facilities do great harm to the environment. For all these reasons, we refuse to consider this energy as “green” or “clean”.
On a positive note, a growing number of countries are ratifying the Treaty on the Prohibition of Nuclear Weapons (TPNW). So the time has also come to say farewell to nuclear energy production.
Despite the troubled times we are going through, and all the difficulties we will still face in the future, let us continue to walk together step by step, supported by the solidarity of our fellow human beings who continue the struggle in the four corners of the world.

Eleven years have passed since the Great East Japan Earthquake and the disaster at TEPCO’s Fukushima Daiichi Nuclear Power Plant.
Nuclear power plants that had been deemed “completely safe” by the government and power companies, exploded one after another. Radioactive materials that were supposedly confined behind “five-layered walls” leaked out into the sea and onto land, causing long-term radioactive contamination.
What must not be forgotten is that society as a whole took the mass production and consumption of electricity for granted, and had subconsciously accepted the propaganda of the government and power companies that justified the use of nuclear power plants. The fact that the electricity generated at the power plant in Fukushima was used, not in Fukushima but in the Tokyo Metropolitan Area, and that many workers were forced to suffer radiation exposure in order to operate the plant, were injustices that had not been recognized by many. This structural injustice continues to this day.
The nuclear disaster was not supposed to happen. Thus, there was no legal system for victim relief and no robust regulation of radioactive materials in the environment. In 2011, when the government set a standard for evacuation that was 20 times higher than the exposure limit applicable to the general public, many people struggled with the question of whether to evacuate, or to remain. Many were forced to evacuate without compensation or support.
The nuclear disaster is not over. At least 30,000 people are still living as evacuees. However, public assistance, including the provision of housing, has already been cut off, leaving behind some evacuees who cannot afford to pay rent.
Even though evacuation orders have been lifted one after another and support for evacuees has been discontinued, many people have not returned to their homes. Younger generations have not returned, and one- or two-person households of elderly people are living scattered in different areas.
Meanwhile, radioactive materials are being spread by human activities once again. The government has decided on a policy of reusing contaminated soil and radioactive waste generated by decontamination, rather than taking the path of safe storage. Furthermore, the dumping of large quantities of treated contaminated water into the ocean is also causing the spread of radioactive materials. Not only does this water contain tritium, but also strontium-90, iodine-129, and other radioactive materials. TEPCO has stated that it will conduct secondary treatment, but information on the amount and type of radioactive materials that will ultimately remain in the water has not been disclosed.
Under the guise of “preventing damaging rumors,” the government continues to spend vast amounts of national taxpayer money on propaganda to convince the public that radioactive materials are not dangerous. However, the spread of radioactive materials is substantial “damage.” The term “damaging rumor” obscures the responsibility of the actual perpetrators, the government and TEPCO, and makes those who point out the risks of exposure and contamination appear as though they also bear responsibility.
After the disaster, all nuclear power plants owned by TEPCO and Tohoku Electric Power Company were shut down, and a “nuclear power plant free” Eastern Japan has existed for the past 11 years. After the shutdown of Kansai Electric Power’s Oi reactors 3 and 4 in September 2013, nuclear power plants across the country were out of operation for close to two years, resulting in a nationwide nuclear power plant free period. Even after operations were restarted, nuclear power plants were shut down one after another due to delays in the construction of anti-terrorism facilities, court injunctions against operations, and other issues such as cracked pipes. The cost of construction and safety measures for nuclear power plants skyrocketed, and nuclear power plants were no longer a “stable” or “inexpensive” power source.
Russia’s military invasion of Ukraine has resulted in many casualties. One after another, Russian troops are attacking and taking control of nuclear power plants in Ukraine. Needless to say, war is the greatest form of environmental destruction and violation of human rights and totally unacceptable. In addition, attacks on nuclear power plants lead to the spread of radioactive materials, endangering the lives and health of many people for a long time. The risk of nuclear power plants becoming targets of attacks was indicated in the past, and unfortunately this nightmare has now become a reality.
We stand with the victims, and in solidarity with people around the world who wish for peace, and we have renewed our determination to move forward to realize a peaceful, nuclear-free world.
Radioactive waste from contaminated water treatment, cleanup postponed. What we saw at the storage site of the Fukushima Daiichi Nuclear Power Plant
March 11, 2022
The contaminated water containing high concentrations of radioactive materials that continues to be generated at TEPCO’s Fukushima Daiichi Nuclear Power Plant (Okuma and Futaba towns, Fukushima Prefecture) is creating contaminated waste in the process of treatment and storage. On April 2, this paper’s team entered the plant premises and visited the storage site. TEPCO and the government plan to discharge the contaminated water into the ocean in the spring of 2023, but the cleanup of the massive amount of radioactive waste has been postponed. (Kenta Onozawa)
◆Enriched liquid waste “To be honest, there is no concrete plan.
We honestly don’t have a concrete plan for how to dispose of the waste,” said a TEPCO spokesperson with a pained expression on his face in a corner of the vast tank area on the west side of Units 1 through 4. In front of us, a covered shed surrounded by concrete walls. A horizontal light blue tank could be seen through a gap in the wall. The dosimeter he had brought with him read around 0.5 microsieverts per hour in the tank area, but the reading jumped to 4 microsieverts per hour near the hut.
The contents of the tank, which emitted intense radiation through the 20-centimeter-thick concrete, were “concentrated liquid waste” generated immediately after the accident. It is the precipitate from the process of desalinating highly contaminated water, which contained salt from the tsunami, and reusing it to cool the nuclear reactors.
The muddy condition makes it difficult to treat, and the high radiation dose makes it inaccessible; when Fukushima Prefecture checked the site in January 2008, the maximum radiation dose inside the wall was 800 microsieverts per hour. This is the annual exposure limit for an average person after spending one hour and 20 minutes at the site.
There are 200 cubic meters of muddy liquid waste and 9,000 tons of supernatant water. The contaminated water treatment process has stabilized and will not increase any further. TEPCO plans to begin experimental treatment in FY2011, but has not even begun to verify the method.
◆Contaminated plastic in “untouchable” reservoirs
To the north of the shed, there is a clearing that rises up like a ring, where the underground reservoir that caused the contaminated water leak in 2001 is buried.
At the time, the storage of contaminated water was on a tightrope. TEPCO, under pressure, dug a hole where a tank could not be built directly under the power lines, covered it with a water shield sheet, and filled it with a total of 24,000 tons of contaminated water, which mainly contained radioactive strontium. However, the water leaked underground and could no longer be used.
Although the contaminated water has been drained out, the plastic materials that were placed in the pond as reinforcement remain heavily contaminated. Standing on the pond, the dosimeter quickly read 3 microsieverts per hour. The spokesperson said in a low voice, “I think we could have removed the contaminated water if we had filled it with purified water, but now that we have filled it with contaminated water, it’s hard to do anything about it.
◆Waste continues to accumulate
The treated water that is planned to be discharged into the ocean is water that has been purified by a multinuclide removal system (ALPS). The treatment process also generates muddy waste, which is stored in a polyethylene container (1.5 meters in diameter, 1.8 meters high, and about 1 centimeter thick) called an HIC.
In the storage area on the south side of the site, the top of the HIC was visible inside the concrete wall. Some of the HICs containing high-dose sludge have already exceeded their useful life, and the number of such HICs will reach 87 at the end of FY2010. There are fears that they may break due to deterioration, and they are under pressure to be transferred to new containers. However, it has taken time to set up measures to protect the workers from radiation exposure, and the replacement of the heavily contaminated containers only began on February 22.
Once the discharge of treated water into the ocean begins, the number of storage tanks, which number approximately 1,000, will gradually decrease. However, there is no plan to eliminate the generation of contaminated water, and the purification process will continue. In the meantime, waste from the treatment process will continue to accumulate, so it is unacceptable to postpone the consideration of a long-term management method.

8 towns and villages near Fukushima nuclear power plant 1,514 earthquake-related deaths 70% relocated 3 times or more
March 6, 2022
In eight towns and villages in Futaba County, Fukushima Prefecture, where evacuation orders were issued after the March 2011 accident at TEPCO’s Fukushima No. 1 nuclear power plant and nearly all residents evacuated in and out of the prefecture, 1,514 people were certified as earthquake-related deaths, and at least 1,025 were found to have moved to new evacuation sites three or more times, according to a new report. Of the 1,514, 136 died after 2004, indicating that the prolonged evacuation has pushed the victims to the edge.
The Mainichi Shimbun requested local governments in Fukushima Prefecture to disclose documents submitted by the bereaved families over the certification of earthquake-related deaths. The documents include a written history leading up to the deaths, and we analyzed their contents. The number of people certified as earthquake-related deaths in the prefecture as a whole was 2,331, about 1.5 times the number of direct deaths (1,605).
A survey of 1,514 people certified as earthquake-related deaths in eight towns and villages in Futaba County (six towns: Namie, Futaba, Okuma, Tomioka, Naraha, and Hirono; two villages: Katsurao and Kawauchi) showed that at least 1,025 people had moved their evacuation sites three or more times before their death. Of these, 248 had moved three times, 267 four times, 211 five times, and 299 six or more times.
A total of 2,034 people, 1,514 in eight towns and villages in Futaba County and 520 in Minamisoma City, which was ordered to evacuate within a 20-kilometer radius of the Daiichi Nuclear Power Plant, were identified as having died as earthquake-related deaths, and 70% of them were in their 80s or older. Those with a history of illness accounted for 80% of the deaths, with pneumonia and heart disease being the most common causes of death. A number of people suffered from depression or worsening dementia as a result of the long-term evacuation.
According to the Reconstruction Agency, more than 90% of those who were certified as earthquake-related deaths in Iwate and Miyagi prefectures affected by the Great East Japan Earthquake died within one year of the disaster. In contrast, in the eight towns and villages in Futaba County and Minamisoma City, almost half of all deaths from related causes occurred after one year had passed.
Applications for earthquake-related deaths from bereaved families are still being filed. However, the passage of time has made it difficult to determine the causal relationship between the deaths, and the certification rate is declining. In Tomioka Town, where 454 people, the largest number in Futaba County, were certified, the rate dropped from 94% in FY12 (83 certified out of 88 applications) to 38% from FY19 to FY21 (17 certified out of 45 total).

Earthquake-related deaths
Deaths are not directly caused by collapsed buildings or tsunamis resulting from earthquakes, but by worsening physical condition due to evacuation after the disaster. Based on the disaster condolence payment system, a review board consisting of doctors and lawyers receives applications from bereaved families, examines them, and certifies them by the local government. If certified, the bereaved family will receive up to 5 million yen. According to the Reconstruction Agency, as of the end of September 2021, 3,784 people in 10 prefectures had been certified for the Great East Japan Earthquake.

(11 Years after the Great East Japan Earthquake) Forest untouched by decontamination, creatures exposed to radiation continue to be affected at the cellular level
March 8, 2022
Eleven years have passed since the accident at TEPCO’s Fukushima Daiichi Nuclear Power Plant.
While decontamination has progressed mainly in residential areas and other areas where people live, vast areas of forests remain largely untouched.
What effect do radioactive materials remaining in the forests have on living creatures and how do they move through the food chain? Researchers are continuing their investigations. (Keitaro Fukuchi)
