The BBC’s Rupert Wingfield-Hayes has been to the radiation zone to meet one of the workers who stayed at the plant Japan quake

Entering the exclusion zone around the crippled Fukushima nuclear power plant is an unnerving experience.

It is, strictly speaking, also illegal. It is an old cliché to say that radiation is invisible. But without a Geiger counter, it would be easy to forget that this is now one of the most contaminated places on Earth.

The small village of Tatsuno lies in a valley 15km (9.3 miles) from the plant. In the sunlight, the trees on the hillsides are a riot of yellow and gold. But then I realise the fields were once neat rice paddies. Now the grass and weeds tower over me.

On the village main street, the silence is deafening – not a person, car, bike or dog. At one house, washing still flaps in the breeze. And all around me, invisible, in the soil, on the trees, the radiation lingers.

But on top of a hill behind the village is a farm – and here there is noise. Two long metal sheds are crowded with cows, nearly 400 of them. Sitting next to a wood stove sipping a cup of coffee is 58-year-old Masami Yoshizawa.

He shouldn’t be here. Nor should his cows. He should be gone and they should be dead. But Mr Yoshizawa is refusing to leave or slaughter his cows.

"I will never be able to grow rice again on this land," he says. "No vegetables, no fruit. We can’t even eat the mushrooms that grow in the woods; they are too contaminated. But I will not kill my cows. They are a symbol of the nuclear disaster that happened here."

From Mr Yoshizawa’s front porch, you can clearly see the tall white chimneys of the nuclear plant. Standing here, it’s easy to understand the anger and hatred people like him feel towards the Tokyo Electric Power Corporation (Tepco).

A Japanese parliamentary report published in July makes it clear that the Fukushima reactor meltdowns were not the unavoidable result of an extraordinary natural disaster. They were a man-made catastrophe, the report says.

But it is also clear the disaster would have been much worse were it not for the actions of hundreds of employees of the same Tepco.

‘Responsible’

In the immediate aftermath of the disaster, the foreign media, including the BBC, hailed the men as the "Fukushima 50".

The Tepco workers have remained largely unknown during the crisisIn fact there were never 50 of them. Hundreds of workers stayed at the plant, braving high levels of radiation to bring the reactors under control. Many are still there today.

And yet almost nothing has been heard from them. No awards, no newspaper articles or TV interviews. We don’t even know their names.

It took us weeks to track one man down and persuade him to talk to us. Even then, he insisted we could not photograph him or use his name.

We meet on a rainy day at a Tokyo park, far away from any crowds. The young man describes how he and a group of other nuclear workers were sent back in to the plant after the first reactor explosion.

"The person who sent us back didn’t give us any explanation," he says. "It felt like we were being sent on a death mission."

I put it to him that what he and his colleagues did was heroic, that they should feel proud. He shakes his head, a slightly anguished look on his face.

"Even when I’m out with friends, it’s impossible to feel happy. When people talk about Fukushima, I feel that I am responsible."

‘Mulitiple stresses’

For an outsider, such a reaction is quite hard to fathom. For help, I turn to psychiatrist Dr Jun Shigemura at Japan’s national defense university. He is one of two doctors who have studied the Fukushima workers.

His research suggests that half of those who fought the reactor meltdowns are suffering from depression and post-traumatic stress symptoms.

"The workers have been through multiple stresses," Dr Shigemura says.

"They experienced the plant explosions, the tsunami and perhaps radiation exposure. They are also victims of the disaster because they live in the area and have lost homes and family members. And the last thing is the discrimination."

Yes, discrimination. Not only are the workers not being celebrated, they are facing active hostility from some members of the public.

"The workers have tried to rent apartments," says Dr Shigemura. "But landlords turn them down, some have had plastic bottles thrown at them, some have had papers pinned on their apartment door saying ‘Get out Tepco’."

‘Not heroes’

Back in the 1960s and 70s, getting rural Japanese communities to accept nuclear power plants was hard.

Dr Shigemura says the workers face discriminationThey were promised new roads and sports facilities. They were promised high paying jobs in the plant. And most of all, they were promised that nuclear power was completely safe.

Now that the lie has been so tragically exposed, the feeling of betrayal is huge.

Before the meltdowns, Seiko Takahashi never thought of activism. Now the middle-aged mother from Fukushima City is a passionate anti-nuclear campaigner. And she admits there is little sympathy for the Fukushima workers.

"They are not heroes for us," she says. "I feel sorry for them, but I don’t see them as heroes. We see them as one block, they work for Tepco, they earned high salaries. The company made a lot of money from nuclear power, and that’s what paid for their nice lives."

And that is the final point. Japan is a country where people identify very closely with the company they work for. People here will often introduce themselves with their company name first, and their own only second.

But those close ties between the Fukushima nuclear workers and Tepco are exacting a terrible psychological toll on the men who saved Japan from a much worse nuclear disaster.

TOKYO (AP) — Radioactive cesium levels in most kinds of fish caught off the coast of Fukushima haven’t declined in the year following Japan’s nuclear disaster, a signal that the seafloor or leakage from the damaged reactors must be continuing to contaminate the waters — possibly threatening fisheries for decades, a researcher says.

Though the vast majority of fish tested off Japan’s northeast coast remain below recently tightened limits of cesium-134 and cesium-137 in food consumption, Japanese government data shows that 40 percent of bottom-dwelling fish such as cod, flounder and halibut are above the limit, Ken Buesseler, a marine chemist at the Woods Hole Oceanographic Institution in Massachusetts, wrote in an article published Thursday in the journal Science.

In analyzing extensive data collected by Japan’s Ministry of Agriculture, Fisheries and Forestry, he found that the levels of contamination in almost all kinds of fish are not declining a year after the March 11, 2011 disaster. An earthquake and tsunami knocked out the Fukushima Dai-ichi plant’s vital cooling system, causing three reactor cores to melt and spew radiation onto the surrounding countryside and ocean.

"The (radioactivity) numbers aren’t going down. Oceans usually cause the concentrations to decrease if the spigot is turned off," Buesseler told The Associated Press in an interview. "There has to be somewhere they’re picking up the cesium."

"Option one is the seafloor is the source of the continued contamination. The other source could be the reactors themselves," he said.

The safety of fish and other foods from around Fukushima remains a concern among ordinary Japanese, among the world’s highest per capita consumers of seafood.

Most fish and seafood from along the Fukushima coast are barred from the domestic market and export. In June, authorities lifted bans on octopus and sea snails caught off Fukushima after testing showed very low levels of radiation.

But the most contaminated fish found yet off Fukushima were caught in August, some 17 months after the disaster. The two greenlings, which are bottom-feeders, had cesium levels of more than 25,000 becquerels per kilogram, 250 times the level the government considers safe.

A government fisheries official, Chikara Takase, acknowledged that the figure for the greenlings was "extremely high," but he added high numbers were detected only in limited kinds of fish sampled in the restricted waters closest to the plant. He acknowledged that "we have yet to arrive at a situation that allows an overall lifting of the ban."

To bolster public confidence in food safety, the government in April tightened restrictions for cesium-134 and cesium-137 on seafood from 500 to 100 becquerels per kilogram. But the step led to confusion among consumers as people noticed more products were barred.

Plant operator Tokyo Electric Power Co. said some radioactive water used to cool the Fukushima reactors leaked into the ocean several times, most recently in April.

"Given the 30-year half-life of cesium-137, this means that even if these sources (of contamination) were to be shut off completely, the sediments would remain contaminated for decades to come," Buesseler wrote in Science.

Experts suspect that radioactive water from the plant is seeping into the ground water at the same time, and is continuing to make its way into the ocean.

Hideo Yamazaki, a marine biologist at Kinki University, agrees with Buesseler’s theory that the cesium is leaking from the Fukushima nuclear plant and that it will contaminate seafood for more than a decade.

He said he believes the plant will continue to leak until cracks and other damage to the three reactors that melted down are repaired. It’s unclear when that work will be completed, or even how, because radiation levels in the reactors are too high for humans or even robots.

"The current levels of contamination in the fish and seafood from the Fukushima coast will continue for a while, perhaps more than 10 years, judging from the progress in the cleanup process," Yamazaki said in an email.

Buesseler, who led an international research cruise off northeastern Japan in 2011 to study the spread of radionuclides from the Fukushima plant, says predicting patterns of contamination requires more than monitoring data on fish. Careful study of the ocean waters and sediments is also needed to determine how quickly the system will recover.

TOKYO (AP) — The utility behind Japan’s nuclear disaster acknowledged for the first time Friday that it could have avoided the crisis.

Tokyo Electric Power Co. said in a statement that it had known safety improvements were needed before last year’s tsunami triggered three meltdowns, but it had feared the political, economic and legal consequences of implementing them.

"When looking back on the accident, the problem was that preparations were not made in advance," TEPCO’s internal reform task force, led by company President Naomi Hirose, said in the statement. "Could necessary measures have been taken with previous tsunami evaluations? It was possible to take action" by adopting more extensive safety measures, the task force said.

The task force said TEPCO had feared efforts to better protect nuclear facilities from severe accidents such as tsunamis would trigger anti-nuclear sentiment, interfere with operations or increase litigation risks. TEPCO could have mitigated the impact of the accident if it had diversified power and cooling systems by paying closer attention to international standards and recommendations, the statement said. TEPCO also should have trained employees with practical crisis management skills rather than conduct obligatory drills as a formality, it said.

The admissions mark a major reversal for the utility, which had defended its preparedness and crisis management since the March 2011 tsunami. The disaster knocked out power to the Fukushima Dai-ichi nuclear plant, leading to the meltdowns, which forced massive evacuations and will take decades to clean up.

The statement was released after TEPCO held its first internal reform committee meeting, led by former U.S. nuclear regulatory chief Dale Klein. His five-member committee oversees the task force’s reform plans.

"It’s very important for TEPCO to recognize the needs to reform and the committee is very anxious to facilitate the reform necessary for TEPCO to become a world-class company," Klein told a news conference. "The committee’s goal is to ensure that TEPCO develops practices and procedures so an accident like this will never happen again."

The reform plans aim to use the lessons learned at TEPCO’s Kashiwazaki-Kariwa plant in northern Japan. The cash-strapped utility wants to restart that plant, but TEPCO officials denied the reform plans are aimed at improving public image to gain support for the plant’s resumption.

"The reforms are intended to improve our safety culture, and we have no intention to link it to a possibility of resuming the (Kashiwazaki-Kariwa) plant," said Takafumi Anegawa, the TEPCO official in charge of nuclear asset management. "We don’t have any preconditions for our reforms."

The Fukushima Dai-ichi plant has been substantially stabilized but is still running on makeshift equipment as workers continue their work to decommission the four damaged reactors, which could take several decades.

Additional safety measures have been installed at nuclear power plants nationwide since the accident under the government’s instructions, including enhancing seawalls, adding backup power and cooling water sources, and developing better crisis management training. But plant operators will be required to take further steps as a new nuclear regulatory authority launched in September steps up safety requirements.

Investigative reports compiled by the government and the parliament panels said collusion between the company and government regulators allowed lax supervision and allowed TEPCO to continue lagging behind in safety steps.

Despite records indicating a major tsunami had once hit off Japan’s northern coast, TEPCO took the most optimistic view of the risk and insisted that its 5.7-meter-high seawall was good enough. The tsunami that struck Fukushima Dai-ichi was more than twice that height.

The company had said in its own accident probe report in June that the tsunami could not be anticipated and that the company did the best it could to bring the critically damaged plant under control, although there were shortfalls that they had to review. TEPCO bitterly criticized what it said was excessive interference from the government and the prime minister’s office.

TEPCO’s Anegawa said the task force plans to compile by the end of the year recommendations "that would have saved us from the accident if we turn the clock back."

TOKYO — In Japan’s largest antinuclear rally since the disaster at Fukushima, tens of thousands of protesters gathered at a park in central Tokyo on Monday to urge the government to halt its restarting of the nation’s reactors.

A protester shouted slogans during a large antinuclear rally in Tokyo.
Organizers said 170,000 people filled a Tokyo square to sing songs, beat drums and cheer on a series of high-profile speakers who called for more Japanese to make their voices heard. The police put the number at 75,000, still making it the biggest gathering of antinuclear protesters since the Fukushima accident last year.

"To stay silent in the wake of Fukushima is inhuman," the Oscar-winning musician Ryuichi Sakamoto told the crowd, which braved soaring temperatures to gather at Yoyogi Park.

Polls suggest that public opinion is still divided over the future of nuclear power in Japan. But a unilateral decision last month by Prime Minister Yoshihiko Noda to start putting the country’s reactors back into use has angered many Japanese and galvanized the antinuclear camp.

Japan’s prime minister ordered workers to remain at the tsunami-crippled Fukushima nuclear plant last March as fears mounted of a "devil’s chain reaction" that would force tens of millions of people to flee Tokyo, a new investigative report shows.

Then-Premier Naoto Kan and his staff began referring to a worst-case scenario that could threaten Japan’s existence as a nation around three days after the March 11 earthquake and tsunami, according to the report by a panel set up by a private think-tank.

That was when fears mounted that thousands of spent fuel rods stored at a damaged reactor would melt and spew radiation after a hydrogen explosion at an adjacent reactor building, according to the panel report.

Yukio Edano, then Japan’s top government spokesman, told the panel that at the height of tension he feared a "devil’s chain reaction" in which the Fukushima Daiichi plant and the nearby Fukushima Daini facility, as well as the Tokai nuclear plant, spiraled out of control, putting the capital at risk.

Kan, who stepped down last September, came under fire for his handling of the crisis, including flying over the plant by helicopter the morning after the disasters hit — a move some critics said contributed to a delay in the operator’s response.

Kan, 65, has spoken of how he was haunted by the specter of a crisis spiraling out of control and forcing the evacuation of the Tokyo greater metropolitan area, 150 miles away and home to some 35 million people.

The private Rebuild Japan Initiative Foundation report also said Japan’s government withheld information about the full danger of last year’s nuclear disaster from its own people and from the United States, putting U.S.-Japan relations at risk in the first days after the accident.

The report, compiled from interviews with more than 300 people, delivers a scathing view of how leaders played down the risks of the meltdowns at the Fukushima Dai-ichi nuclear plant that followed a massive March 11, 2011 earthquake and tsunami.

It paints a picture of confusion during the days immediately after the accident and says the U.S. government was frustrated by the scattered information provided by Japan and was skeptical whether it was true.

The U.S. advised Americans to leave an area within 50 miles of the plant, far bigger than the 12-mile Japanese evacuation area, because of concerns that the accident was worse than Japan was reporting.

The misunderstandings were gradually cleared up after a bilateral committee was set up on March 22 and began regular meetings, according to the 400-page report.

The report, compiled by scholars, lawyers and other experts, credits then-Prime Minister Naoto Kan for ordering Tokyo Electric Power Co., the utility running the plant, not to withdraw its staff and to keep fighting to bring it under control.

TEPCO’s president at the time, Masataka Shimizu, called Kan on March 15 and said he wanted to abandon the plant and have all 600 TEPCO staff flee, the report said. That would have allowed the situation to spiral out of control, resulting in a much larger release of radiation.

A group of about 50 workers was eventually able to bring the plant under control.

TEPCO, which declined to take part in the investigation, has denied it planned to abandon Fukushima Dai-ichi. The report notes the denial, but says Kan and other officials had the clear understanding that TEPCO had asked to leave.

But the report criticizes Kan for attempting to micromanage the disaster and for not releasing critical information on radiation leaks, thereby creating widespread distrust of the authorities among Japanese.

Kan’s office did not immediately respond to requests for comment on the report.

Kan acknowledged in a recent interview with The Associated Press that the release of information was sometimes slow and at times wrong. He blamed a lack of reliable data at the time and denied the government hid such information from the public.

It will take decades to fully decommission Fukushima Dai-ichi. Although one of the damaged reactor buildings has been repaired, others remain in shambles. A group of journalists, including a reporter from The Associated Press, were given a tour of the plant on Tuesday.

Workers have used tape to mend cracks caused by freezing weather in plastic hoses on temporary equipment installed to cool the hobbled reactors.

"I have to acknowledge that they are still rather fragile," plant chief Takeshi Takahashi said of the safety measures.

The area is still contaminated with radiation, complicating the work. It already has involved hundreds of thousands of workers, who have to quit when they reach the maximum allowed radiation exposure of 100 millisieverts a year.

The report includes a document describing a worst-case scenario that Kan and the chief of the Japan Atomic Energy Commission secretly discussed two weeks after the disaster.

That scenario involved the possibility of more nuclear fuel rods burning, causing the release of more radiation and requiring the evacuation of a much wider region, including Tokyo.

The report also concludes that government oversight of nuclear plant safety had been inadequate, ignoring the risk of tsunami and the need for plant design renovations, and instead clinging to a "myth of safety."

"The idea of upgrading a plant was taboo," said Koichi Kitazawa, a scholar who heads the commission that prepared the report. "We were just lucky that Japan was able to avoid the worst-case scenario. But there is no guarantee this kind of luck will prevail next time."

After the quake and tsunami struck, three reactors melted down and radiation spewed widely through eastern Japan, forcing tens of thousands of residents to evacuate from the area around the plant.

TEPCO managed to avert the worst scenario by pumping water, much of it from the sea, into Dai-ichi’s damaged reactors and spent fuel pools. The reactors were stabilized by December.

A year after the disaster, however, Fukushima Dai-ichi still resembles a vast wasteland. High radiation levels hamper a cleanup that is expected to take decades.

The damaged 125-foot-tall No. 2 reactor building stands like a bird’s nest of twisted steel beams. A TEPCO official who accompanied foreign media to the plant on Tuesday said metal debris was being painstakingly removed by giant cranes and other equipment as radiation doses were too high for workers.

Another challenge is keeping a new cooling system, built from a myriad of technologies and prone to breaking down, running without major glitches.

"An earthquake or tsunami like the ones seen a year ago could be a source of trouble for these (cooling) systems. But we are currently reinforcing the spent fuel pool and making the sea walls higher against tsunamis," Takeshi Takahashi, the Dai-ichi plant’s manager, told reporters. "A series of backup systems is also being put in place in case one fails."

Edano on Tuesday acknowledged he had feared the worst around March 14-15. "I was working with a strong sense of crisis that under various circumstances, such a thing may be possible," he told a news conference in Tokyo.

But he defended his silence as government spokesman.

"I shared all information. Back then, I was not in a position where I, as someone who is not an expert, could irresponsibly speak about my own personal impressions and my sense of crisis," he told a news conference.

"I conveyed assessments and decisions of the government, government agencies and experts," he added.

The panel report said some of Kan’s seemingly inexplicable behavior stemmed from his belief that TEPCO was going to abandon the plant and the accident would spiral out of control.
An irate Kan blasted TEPCO on Marc
h 15, yelling: "What the hell is going on" in an outburst overheard by a Kyodo News reporter and quickly reported around the globe. "I want you all to be determined," he was quoted as telling utility executives.

The utility ultimately left a corps of workers who were dubbed the "Fukushima Fifty" by media and won admiration at home and abroad as they risked their lives to contain the crisis, although their names were never formally made public.
