Fukushima Update - 5 years after Nuclear Power Plant meltdown

Japan Press Weekly : 25 February 2016

On March 11, 2011, the Fukushima Daiichi Nuclear Power Plant was hit by a magnitude-9 earthquake and massive tsunami, which led to the nuclear meltdown at the plant.

Nearly five years on, even now, endless efforts are being made to contain the nuclear accident. There is still a long way to go before full decommissioning of the crippled reactors.

On the sea side of the plant stand four reactor buildings. At the No.3 reactor building (third from the right), repair work on its roof, which was blown off by an internal hydrogen explosion five years ago, has yet to be finished. Three other reactor buildings, which were also damaged by internal explosions, now have temporary white covers under which recovery works is taking place.
The radiation level is still dangerously high at the plant. It is feared that the 120-meter high funnels attached to the reactor buildings may collapse due to excessive corrosion, but high radiation doses prevent workers from even getting close to them to repair or replace them.

On the hill side, a thousand-plus water storage tanks are placed close together and are full of highly-radioactive water. The number of tanks keeps increasing as the plant operator pumps up around 500 tons of toxic radioactive water from the site every day. The storage pit is gradually encroaching on nearby woods due to the scarcity of space

5 Years Later Fukushima Still Spilling Toxic Nuclear Waste Into Sea, Top Execs Face Criminal Charges
Ecowatch : 1 March 2016
 
Five years after the worst nuclear disaster since Chernobyl, three former executives of Tokyo Electric Power Co. (Telco) were indicted Monday for allegedly failing to prevent the tsunami-sparked crisis at the Fukushima Daiichi nuclear plant.
 
Former Tepco chairman Tsunehisa Katsumata and former vice presidents Ichiro Takekuro and Sakae Muto were charged with contributing to deaths and injuries stemming from the nuclear meltdown triggered by the March 11, 2011 earthquake and tsunami.

Their indictment is Japan’s first criminal action taken in connection with the nuclear crisis. If convicted, the three men could face up to five years in prison or a penalty up to 1 million yen.
According to The Japan Times, the trio have been blamed for injuries to 13 people, including Self-Defense Forces personnel, hydrogen explosions at the plant and the deaths of 44 patients who were forced to evacuate from a nearby hospital. The indictment seeks to answer in court the question of whether the three bosses should be held criminally responsible for the disaster, the publication stated.

Tepco had been warned years earlier about the dangers of an earthquake and a tsunami hitting the plant. According to The Japan Times, the inquest committee said the former executives received a report by June 2009 that the plant could be hit by a tsunami as high as 15.7 meters and that they “failed to take pre-emptive measures knowing the risk of a major tsunami.”

The three executives were not taken into custody and are likely to plead not guilty to the charges arguing that it was impossible to predict the size of the tsunami, according to Abc.net.au. The trial is not expected to begin until next year.

Still, many have been encouraged by the indictment.

“I’m full of emotion,” Ruiko Muto, head of a campaign group pushing for a trial, told a Tokyo press briefing. “This will be a great encouragement for hundreds of thousands of nuclear accident victims who are still suffering and facing hardship.”

Environmental group Greenpeace also called the charges against the Tepco executives a step forward for Fukushima victims.
“The court proceedings that will now follow should reveal the true extent of Tepco’s and the Japanese regulatory system’s enormous failure to protect the people of Japan,” Hisayo Takada, deputy program director at Greenpeace’s Japan office, said in a statement. “Tepco and the Japanese regulator continue to ignore demands to disclose key details of what they know about the causes of the accident. The hundred thousand people who still can’t return home deserve to have all the facts.”
In response to the indictment, a Tepco spokesman said, “We will continue to do our utmost to sincerely address the issue of compensation, decontamination and decommissioning of the plant, and at the same time we express our unflagging resolve to ensure strengthening the safety measures at our nuclear power plant.”

The nuclear meltdown forced the evacuation of 160,000 locals who lived around the power plant with many who will never return. The devastating fallout continues to this day, as Scientific American wrote in their upcoming issue:

The plant has yet to stop producing dangerous nuclear waste: its operator, the Tokyo Electric Power Company (Tepco), currently circulates water through the three melted units to keep them cool—generating a relentless supply of radioactive water. To make matters worse, groundwater flowing from a hill behind the crippled plant now mingles with radioactive materials before heading into the sea.
 
Tepco collects the contaminated water and stores it all in massive tanks at the rate of up to 400 metric tons a day. Lately the water has been processed to reduce the concentration of radionuclides, but it still retains high concentrations of tritium, a radioactive isotope of hydrogen. Disputes over its final resting place remain unresolved. The same goes for the millions of bags of contaminated topsoil and other solid waste from the disaster, as well as the uranium fuel itself. Health reports, too, are worrisome. Scientists have seen an increase in thyroid cancers among the children who had lived in Fukushima at the time, although it is too early to tell if those cases can be attributed to the accident.
 
Indeed, as Beyond Nuclear reported in October, a study examining children who were 18 years and younger at the onset of the Fukushima nuclear meltdown found an increase in thyroid cancers, as predicted by World Health Organization initial dose assessments.

Despite the environmental and human health catastrophe—as well as widespread public opposition—Japan restarted its first nuclear reactor in August.

“Five years since the Fukushima accident began, Japan’s nuclear regulator is repeating the same kind of mistakes that led to the Fukushima nuclear disaster. Last week, the plutonium-fueled Takahama 4 reactor was restarted, just days after a radioactive leak in the primary coolant system,” Kendra Ulrich, senior global energy campaigner at Greenpeace Japan, said in a statement Monday.

“Japan’s nuclear regulator continues to look the other way on major safety issues. The government continues to press ahead with nuclear restarts despite unresolved safety problems that put the public at risk. It’s time to break free from nuclear and embrace the only safe and clean technology that can meet Japan’s needs—renewable energy.”

Last week, Greenpeace’s Rainbow Warrior vessel surveyed waters near the Fukushima plant to take samples from the seabed to be analyzed in independent laboratories in Japan and France.
“It’s very important (to see) where is more contaminated and where is less or even almost not contaminated,” Greenpeace’s Jan Vande Putte told AFP, stressing the importance of such findings for the fishing industry.
