From the Reality of Chernobyl and Fukushima
Date: Friday, October 7 – Monday, October 10, 2016
Venue: Main Hall, Fukushima Gender Equality Centre 1-196-1 Kakunai, Nihonmatsu, Fukushima, 964-0904
The Citizen-Scientist International Symposium on Radiation Protection (CSRP), a politically, financially, ideologically and religiously independent non-profit organization, has been committed to keeping to minimum the damages on health and environment caused by the Tokyo Electric Fukushima Daiichi Nuclear Power Plant disaster that followed the Great East Japan Earthquake and Tsunami in March 11, 2011.
CSRP has been inviting administrative officials, researchers, NGOs, member experts of governmental inquiry commissions and international organizations working on radiation protection, etc. Since around the 3rd CSRP, this approach has started to bear fruit, because scientists and other stakeholders with different positions and paradigms began to share the same table of discussion, thus gradually making possible constructive exchange of views.
In the course of this approach, however, we began to encounter a new challenge that may concern the premise of the CSRP; the deeper we got into scientific discussion, the higher the hurdle for participation got for the general public, especially for younger generations. Also, the diversity of voices were to be alienated from pointed scientific discussions that are decisive for the decision-making of the radiation protection of the general public. This lead us to some interrogations : “Isn’t ‘science’ given too much importance in decision-making?”; “Is ‘science’ the only way for citizens to bring today’s situation under their power?”
While always continuing to examine new scientific findings with respect to health, environmental and social impacts of low-dose exposure, we added the theme of “Between Art and Science” to the 5th symposium last year, exposed various art works inspired by nuclear power and nuclear disasters, and organized a panel discussion with artists and scientists. This was the CSRP’s new attempt to question “science” and “scientificity” with a view to reexamining the relationships between science, art and philosophy before and after the modernity. The 6th CSRP of this year, held in the city of Nihonmatsu, Fukushima Pref., will collaborate with the Institute of Regional Creation by Arts, the University of Fukushima, to cosponsor the Fukushima Biennale 2016. We hope this new attempt will bring new visions to the participants.
As a place to learn and make full use of new findings exploring the effects of low-dose radiation exposure accumulating day by day, and to think together about the rights of people facing the consequences of the nuclear accident and about what epidemiology and public health should do in order to minimize the damage, we open the 6th Citizen-Scientist International Symposium on Radiation Protection.
Resuming Monju reactor operations may cost over ¥540 billion
The cost of resuming operations at Japan’s trouble-plagued Monju prototype fast-breeder nuclear reactor is estimated to top ¥540 billion ($5.2 billion), the science ministry says.
The estimate was presented Friday at a meeting of government and private-sector officials who discussed the fate of the reactor in Tsuruga, Fukui Prefecture.
More than ¥1 trillion ($9.7 billion) has been spent on Monju, but it has only operated for a total of 250 days in the past 20 years due to a series of problems, including a leak of sodium coolant.
The government is considering options, including decommissioning the reactor. It plans to make a decision by the end of this year.
The ministry said the costs may far exceed ¥540 billion if the safety screening process by regulators is lengthy. The estimate does not include expenses for decommissioning the reactor.
The science ministry wants Monju to be maintained while the industry ministry is opposed to the idea.
Opposition to keeping Monju in place is expected to grow if a massive amount of money is needed for it to go back online.
The meeting brought together science minister Hirokazu Matsuno and industry minister Hiroshige Seko as well as nuclear industry executives, including Satoru Katsuno, chairman of the Federation of Electric Power Companies of Japan.
Federation estimates Fukushima nuke plant cleanup costs, redress may rise to ¥8 trillion ($77.10 billion)
An industry group has estimated costs for decontamination work at the disaster-struck Fukushima nuclear plant and compensation for nuclear damage to be around ¥8 trillion ($77.10 billion) more than the current official projection, a source said Thursday.
The Federation of Electric Power Companies of Japan, which consists of the country’s 10 electric power companies, has informally asked Prime Minister Shinzo Abe’s government to use state funds to cover the extra costs, the source also said.
The costs are supposed to be covered by the utilities, including Tokyo Electric Power Company Holdings Inc., operator of the crippled Fukushima No. 1 nuclear power plant, where three reactors melted down in the aftermath of the March 2011 quake-tsunami disaster. The government is cautious about using taxpayer money to deal with the issue, the source said.
Under the current estimate, compensation payments are projected to total ¥5.4 trillion, while decontamination costs are forecast to reach ¥2.5 trillion.
Tepco and other nuclear power plant operators have paid contributions for compensation payments to a state-backed fund. As for decontamination costs, the fund will seek to retrieve that money by selling Tepco shares that it owns.
Govt. Mulls Ways to Promote Fukushima Produce
The Japanese government plans to create ways to encourage consumers to buy food from Fukushima Prefecture. The area still suffers from the perception that its foodstuffs are unsafe due to the 2011 Fukushima Daiichi nuclear power plant accident.
Reconstruction Minister Masahide Imamura and senior government officials held a meeting on Friday.
The officials reported that a lot produce and processed foods from Fukushima are forced to be sold at prices lower than their pre-accident levels.
They explained farmers and food producers from the region face numerous challenges, such as fewer sales routes and reluctance to buy their products.
They decided to offer benefits to consumers who purchase the food.
Imamura stressed simply advertising won’t be enough and he wants the officials to create a framework that will entice consumers. He noted giving them rewards in a point system is one idea.
Promoting Fukushima Rice and Sake
On the Issue of Japan, Fukushima and Rice
In Japan, rice is life. The word for “life” is also the word for “meal” or “food.” The importance of rice to the Japanese people cannot be overstated. The word for rice has been called “emotive.” Damage to Japan’s rice crops goes beyond simple damage to the diet. To be confronted with a shortage of rice calls forth powerful feelings of deprivation in the Japanese. Japanese rice, irradiated by the events of “3/11,” is in danger.
“3/11” is what the Japanese call the series of deadly disasters which struck northern Japan in March of 2011; the earthquake, tsunami, and the Fukushima Daiichi nuclear power plant meltdown. Northern Japan was devastated and recovery will take many decades.
When the Fukushima Daiichi nuclear power facility was badly damaged by irradiation, local crops, including batches of rice grown in Fukushima, found to be badly affected by radiation, were swiftly removed from the market.
Five years after the quake, Fukushima rice producers still have difficulty marketing their produce. But the Japanese government, working in tandem with nonprofits and private organizations, has developed a positive and creative response to the Fukushima food crisis.
The Rice Peace Project Seminar, held on September 19, 2016 in New York, was inspired by the initiatives of a Japanese government supported campaign working together with non-profits, corporate projects, and organizations, including the NPO Project 88.
The NPO Project 88, which takes name from the 88 processes of rice production, mobilizes Japanese high-quality rice as an emergency relief food. Developing tasty, nutritious, non-GMO, low pesticide, and allergen-free, organic and gluten-free rice products is also central to NPO Project 88’s mission, helping to spread peace and disaster-relief in the world through rice.
The Rice Peace Project Seminar, held to publicize the efforts of the NPO Project 88, featured three speakers from Japan. Mrs. Akie Abe, spouse of Prime Minister Shinzo Abe, Mr. Hiroshi Sakurai, President of the sake brewery Asahi Shuzo, and Ms. Nari Takahashi, President of NPO Project 88. The speeches were followed by a sushi tasting prepared by Sushi Chef Yoichi Akashi of Kappo Akashi using Eco-rice as well as a tasting of “Dassai” sake, the sake Prime Minister Abe offered President Obama during the U.S. President’s 2014 visit to Japan.
Jeff Santos, CEO of the Santos Media Group who hosted the seminar, introduced Mrs. Akia Abe. Santos described Mrs. Abe as an activist. Abe is actively engaged in supporting the NPO Project 88 and in promoting Fukushima’s agricultural industry by creating Yamato No Kokoro sake from rice produced in Fukushima.
Mrs. Akie Abe said that in 2011, in the wake of the Tohoku earthquake, she realized the importance of supporting Japanese food production, especially rice. With the encouragement of US Ambassador to Japan, Caroline Kennedy, Abe began to support the production of Fukushima rice and sake,
Abe described the production of rice in Japan as highly political. She said that 150 years ago, after extensive warring between the Chochu and Aizu clans. the two prefectures began to cultivate rice for sake and to brew sake, jointly. The joint effort was successful and the two prefectures now live in harmony.
Abe said that for Japanese, now as always, rice and sake are spiritual foods. “In Japan, we like to get our hands dirty [working the land.] We are a part of nature. We owe our gratitude to nature. It is my pleasure to work with rice producers and sake producers.”
She closed with a warm invitation: “Please enjoy the sushi and sake tasting today and please also come to Japan to enjoy them!”
Hiroshi Sakurai, President of Sake Brewery Asahi Shuzo, opened with praise for Japanese sake in general and Asahi Shuzo’s sake in particular. “Sake has to be ‘oishii’ (delicious) If it is not delicious what is the point of creating it? And our sake is especially ‘oishii!’”
Sakurai said that he wanted to show two world leaders enjoying Japanese sake, Prime Minister Abe and US President Barack Obama. Sakurai’s photo array displayed pictures from the U.S. President’s 2014 visit to Japan.
Sakurai said that his company, Asahi Shuzo, had partnered with the king of rice producers, Yamada Nishiki, accounting for 6.5 percent of total rice production in Japan. He has a staff of 100 and his employees are the best. Production is entirely by hand- they do not use machines. Production is around the clock, 24/7, to produce “oishii” sake.
Sakurai said that rice production in Japan is very eco- friendly. They recycle all that remains from rice production, such as rice husks, used to make sembei, or rice milk.
In closing, he said: “We are eager to promote our sake and we hope you enjoy the tasting.”
Nari Takashashi, President of NPO Project 88. Ms. Takahashi said that rice was the first food served to Fukushima quake victims. It was sometimes all that aged survivors could eat. And for those who could not eat plain rice she and her company developed soft rice cakes. They were very popular, as were their cream puffs.
Takahashi said that some kids with allergies couldn’t eat even the rice cookies or cream puffs. So she developed allergy-free cookies made with rice powder and delivered to the schools. Kids loved them.
Takahashi said that the application for allergy free products goes well beyond Fukushima. Survivors of the Kumamoto quake this past April are their next potential customers. She believes there is a huge market for these products world wide, especially to disaster survivors and to millennials.
After this spirited set of speeches, it was no surprise that the sushi and sake tastings were extraordinary.

Sendai N°1 nuclear reactor shuttered for safety work
Nuclear reactor buildings of the Kyushu Electric’s Sendai nuclear power plant in southern Kagoshima in 2015.
Japan nuclear reactor shuttered for safety work
TOKYO: A reactor at the centre of Japan’s national debate over nuclear power was halted on Thursday (Oct 6) under stricter post-Fukushima safety standards, as Tokyo struggles to bring back atomic energy.
Utility Kyushu Electric is shutting down the No. 1 reactor at its Sendai plant in southern Kagoshima for a few months of inspections and maintenance, leaving Japan with just two operating reactors.
But there is speculation that the reactor’s safety work could drag on longer.
Thursday’s shutdown follows demands from the region’s top politician that Kyushu Electric conduct extra safety inspections at its two operating reactors in the Sendai plant – after deadly quakes hammered a neighbouring prefecture in April.
Last month, the company refused governor Satoshi Mitazono’s demands to immediately shut down the reactors over safety concerns.
But it agreed to what it called “special inspections” in addition to regular maintenance work. Sendai’s No. 2 reactor will be shut down for a similar review starting in December.
Dozens of reactors were switched off in the wake of the March 2011 Fukushima accident, the worst nuclear disaster in a generation.
Anti-atomic sentiment still runs high five years later, challenging a push by Prime Minister Shinzo Abe and utility companies to switch Japan’s stable of reactors back on.
The catastrophe forced resource-poor Japan to turn to expensive fossil fuels to plug its energy gap, but fears about the safety of nuclear power and radiation exposure linger.
The two Sendai reactors were restarted last year under new safety regulations brought in after Fukushima, where reactors went into meltdown in March 2011 after a huge earthquake and tsunami.
Another reactor has been restarted at the Ikata plant in western Japan.
Opposition to nuclear power has seen communities across the country file lawsuits to prevent restarts, including the Sendai plant.
The residents argued that the plant’s operator underestimated the scale of potential earthquakes and volcanic eruptions that could hit the region. A court rejected their argument and ordered restarts.
Fukushima Cleanup Talks Put Tepco Survival Risk in Focus
Tokyo Electric Power Co. is still struggling to put the Fukushima nuclear disaster behind it, admitting this week that paying for decommissioning the plant in one go risks leaving it insolvent.
The cost to insure debt in Japan’s biggest utility climbed to a seven-month high of 89 basis points on Oct. 5 after President Naomi Hirose said after a meeting in Tokyo with a government commission that the company is asking for help in avoiding financial ruin. Tepco has already received state aid for compensation and decontamination.
The March 2011 nuclear accident and its fallout will ultimately cost more than 11 trillion yen ($106 billion), according to a study by academics including Kenichi Oshima, a professor of economics at Ritsumeikan University. Tepco has estimated that decommissioning alone will cost about 2 trillion yen. Investors should hold off buying bonds of other utilities until there is more clarity on how the government will close the Fukushima plant, according to BNP Paribas SA.
“Now is not the best time to be investing in electricity utility bonds, with discussions going on about nuclear plant decommissioning, and the potential for spreads to widen,” said Mana Nakazora, chief credit analyst at BNP Paribas in Tokyo. Even so, she added, “the government has little choice but to take measures to avoid a default by Tokyo Electric.”
While Prime Minister Shinzo Abe’s government has committed to provide up to 9 trillion yen for compensation to individuals and business hurt by the Fukushima disaster and for decontaminating areas affected, that figure doesn’t include decommissioning of the nuclear plant itself, according to a report by Moody’s Investors Service last month.
Scrapping the Fukushima reactors may take 30 years to 40 years, and Tokyo Electric will only start removing debris from the plant from in 2021, a decade after the incident, according to the utility’s road map for dealing with the remnants of the disaster.
In speaking to reporters, Tepco President Hirose was probably making a public case for more government support, according to Yutaka Ban, the chief credit analyst at SMBC Nikko Securities Inc. in Tokyo. Ban said he saw little probability that support will be withheld.
“Things will likely settle down” after the government adopts the new measures, said Ban. “Without government support, the costs would be extremely high.”

Tepco’s credit-default swaps have come down from as high as 1,762 basis points in October 2011, according to data provider CMA. The utility has said it plans to return to the bond market by the end of the fiscal year to March 2017. Jun Oshima, a spokesman for Tokyo Electric, said that plan is still in place. It stopped issuing notes after the Fukushima disaster.
The extra yield on Tepco’s 1.155 percent bonds due in 2020 was 64 basis points more than sovereign debt, the lowest since before the Fukushima disaster, according to Bloomberg-compiled prices. The spread on Osaka-based Kansai Electric Power Co.’s 0.976 percent notes due in 2020 was 39 basis points.
Tokyo Electric has a Ba3 rating from Moody’s and BB- score from S&P Global Ratings, both three levels below investment grade.
“Decommissioning is currently the biggest unknown, and clarity matters in terms of credit,” said Mariko Semetko, a Moody’s analyst in Tokyo. “The lack of clarity there has been holding back the credit quality.”
Radiation Brain Moms and Citizen Scientists: The Gender Politics of Food Contamination after Fukushima
by Aya Hirata Kimura (Author)
Following the Fukushima Daiichi Nuclear Power Plant disaster in 2011 many concerned citizens—particularly mothers—were unconvinced by the Japanese government’s assurances that the country’s food supply was safe. They took matters into their own hands, collecting their own scientific data that revealed radiation-contaminated food. In Radiation Brain Moms and Citizen Scientists Aya Hirata Kimura shows how, instead of being praised for their concern about their communities’ health and safety, they faced stiff social sanctions, which dismissed their results by attributing them to the work of irrational and rumor-spreading women who lacked scientific knowledge. These citizen scientists were unsuccessful at gaining political traction, as they were constrained by neoliberal and traditional gender ideologies that dictated how private citizens—especially women—should act. By highlighting the challenges these citizen scientists faced, Kimura provides insights into the complicated relationship between science, foodways, gender, and politics in post-Fukushima Japan and beyond.
Editorial Reviews
Review
“Riveting and smart, Radiation Brain Moms and Citizen Scientists tracks the efforts made by citizens in post-Fukushima Japan to ensure the safety of their food from radioactive contamination. In the face of state neglect and criticism from fellow Japanese, these initiatives display a ‘soft’ boldness (versus activist politics). Interweaving stories of citizen scientists and ‘radiation brain moms’ with sharp theoretics that deconstruct the entanglements of science, neoliberalism, and postfeminism at work, this book is at once powerful and timely.”
(Anne Allison, author of Precarious Japan)
“Based on careful research, extensive fieldwork, and a judicious use of political and feminist theory, this book’s relevance to political and social developments extends beyond Japan’s borders. It is a reminder of the ongoing effects of the Fukushima disaster in Japan at a time when these effects are being increasingly ignored by the global media. A timely and important book, Radiation Brain Moms and Citizen Scientists will appeal to scholars of contemporary Japanese society as well as science and technology studies scholars, especially those interested in the gender dimensions of science and technology.”
(Tessa Morris-Suzuki, author of Borderline Japan: Foreigners and Frontier Controls in the Postwar Era)

Radioactive water leaks from storage tank at Fukushima plant
The latest contaminated water leak at the Fukushima No. 1 nuclear power plant occurred at a flange-type storage tank, whose seams are connected by bolts.
Up to 32 liters of radioactive water leaked from a storage tank at the crippled Fukushima No. 1 nuclear plant, but the contaminated liquid has been contained, Tokyo Electric Power Co. said Oct. 6.
The leaked water is currently within barriers surrounding the tank that are designed to block the flow of fluids, TEPCO, the plant’s operator, said.
The liquid contained water that had been treated to remove radioactive strontium and other substances, as well as highly contaminated water from the bottom of the tank that was stored shortly after the nuclear accident started in 2011.
A radioactivity level of 590,000 becquerels of beta ray-emitting materials was detected per liter of the leaked water.
The water seeped out of a tank with bolted seams on its sides, which are more prone to leaks than those with welded walls.
TEPCO continues to use the bolted containers despite the risk because production of welded tanks cannot keep pace with the buildup of contaminated water, mainly from groundwater entering the damaged reactor buildings, at the nuclear plant.
Japan Political Pulse: A helping hand following radiation misfortune
Recently former Prime Minister Junichiro Koizumi, 74, was seen talking to 62-year-old Prime Minister Shinzo Abe. Their encounter was recorded on a photo page of the Sept. 29 issue of the weekly magazine Shukan Bunshun.
The scene was Aoyama Funeral Hall in Tokyo, where they had attended the Sept. 15 funeral of former Liberal Democratic Party (LDP) Secretary-General Koichi Kato and were waiting for their cars to arrive. For about 90 seconds the “master and disciple” stood side by side. Below are the details of Koizimi’s comments and the prime minister’s reaction, which didn’t appear in Shukan Bunshun.
Koizumi: “Why don’t you totally eliminate nuclear power plants?”
Abe: (Faint smile, bow)
Koizumi: “Having zero nuclear power plants is cheaper. Why don’t you understand such a simple thing? It’s all lies, what the Ministry of Economy, Trade and Industry is saying. The things advocates of nuclear power plants are saying — they’re all lies. Don’t be fooled.”
Abe: (Wry smile, bows again, and with head kept low heads to official vehicle)
Koizumi is currently pouring his efforts into a fund to support those who say they were affected by radiation during “Operation Tomodachi,” a U.S. Armed Forces operation to support Japan in the wake of the March 2011 Great East Japan Earthquake and tsunami.
Over 400 soldiers from the USS Ronald Regan aircraft carrier and accompanying ships complained of ill-health after helping in rescue efforts following their urgent dispatch to the seas off Fukushima Prefecture in the wake of the earthquake, tsunami and ensuing meltdowns at the Fukushima No. 1 Nuclear Power Plant. Some of them are said to have died from causes including leukemia.
The aircraft carrier fleet worked intermittently in a radiation plume from the stricken power plant between March 13 and 17, 2011. After returning home from Japan, a stream of soldiers developed ailments including brain tumors and thyroid cancer. The nuclear plant’s operator, Tokyo Electric Power Co. (TEPCO), and the Japanese and U.S. governments acknowledged that they had been exposed to low-level radiation, but do not accept a causal relationship between exposure and their illnesses.
Koizumi learned that some soldiers had left the military at a young age, had no insurance and couldn’t pay their medical fees. It was in May this year that the former prime minister traveled to the United States and directly inquired about their circumstances.
Former soldiers earlier filed a lawsuit against parties including TEPCO, and oral arguments over whether jurisdiction of the case should lie in Japan or the United States were heard in an appeals court in California on Sept. 1. At the time, a Japanese government adviser is said to have supported an agent for TEPCO, stating that radiation exposure is the responsibility of the U.S. military.
Koizumi, who read a note on the hearing (carried in the Sept. 9 issue of the magazine Shukan Kinyobi), responded immediately.
“This is embarrassing. They were relief efforts for Japan, right? The American judge is said to have been appalled,” he was quoted as saying.
On July 5, Koizumi appeared in a news conference with figures including former Prime Minister Morihiro Hosokawa, 78, and Tsuyoshi Yoshiwara, 61, an adviser at The Johnan Shinkin Bank, to announce the start of fundraising activities to help the U.S. soldiers. Koizumi himself approached the Japan Business Federation (Keidanren) but was turned away on the grounds that TEPCO is a member of the federation.
Reinforcements have nevertheless appeared on the funding front. Japanese architect Tadao Ando, 75, posed the following question: “Mr. Koizumi, will you come to Osaka and give a lecture? I’ll assemble 1,000 people. With a fee of 10,000 yen per person, that’ll bring in 10 million yen.”
When Koizumi appeared at the lecture in August, 1,300 people turned up. The same style of lecture is due to be held in Tokyo on Nov. 16, organized by the head of a group of managers of small- and medium-sized enterprises. Additionally, the president of a solar power generation company provided 10 million yen.
Through these efforts, the total has climbed to 50 million yen. Koizumi apparently hopes to amass 100 million yen by next spring.
The connection between radiation exposure and the development of illness is delicate. There’s a possibility of developing cancer, but there are doubts about whether a person would suddenly die, experts say.
On Sept. 7, Koizumi spoke at the Foreign Correspondents Club of Japan in Tokyo’s Yurakucho district. He was asked if it was responsible to talk about damage from radiation exposure without presenting scientific evidence.
Below is the gist of his reply:
“I’m no longer a member of the government. I’m a civilian. There are people who are actually suffering. It’s common sense for me to support them.”
Fundraising and service instead of criticism; denial of the perception of saying, “Radiation exposure is the responsibility of the U.S. military” to protect nuclear power policies … I support this form of common sense from our former prime minister. (By Takao Yamada, Special Senior Writer)

Storage tank leaks at Fukushima Daiichi plant
Workers at the crippled Fukushima Daiichi nuclear plant have found a leak of highly radioactive water from a waste water tank.
Its operator, Tokyo Electric Power Company, says the water likely leaked from a seam of the tank.
The leaked water was spotted on Wednesday on the side of one of an array of steel tanks holding contaminated water that is continuously generated at the site.
TEPCO’s analysis found 590,000 becquerel per liter of beta-emitting radioactive materials in the water.
Tokyo Electric estimates that 32 liters of such highly radioactive water had trickled out, mixed with rainwater, and remained within a barrier around the tank.
Workers moved water in the tank to another one to lower the water level enough to halt the leak.
The leaking cylindrical tank is made by splicing steel plates with bolts. But they have had waste water leaks in the past from seams.
The operator has been replacing these leak-prone tanks with new seamless ones. But the increasing volume of waste water makes it difficult for the utility to completely do away with the old ones.
Fire destroys Fukushima nuclear disaster evacuee housing
Fueled by strong winds, fire engulfs temporary housing at the Yoshima industrial park in Iwaki, Fukushima Prefecture, on Oct. 6, 2016.
IWAKI, Fukushima — A fire on Oct. 6 destroyed temporary housing for residents of Okuma, Fukushima Prefecture, who evacuated here due to the Fukushima No. 1 Nuclear Power Plant disaster, police said.
The fire broke out at around 4:25 p.m. and destroyed 19 homes in four single-story, prefabricated wooden buildings at the Yoshima industrial park in Iwaki. According to prefectural police, a 16-year-old boy was treated for smoke inhalation. The Okuma Municipal Government will supply the five households that lost their residences with housing elsewhere.
There were 72 households living in 86 of the 31-building complex’s 122 residences. Some 90 percent of Okuma residents’ original homes are within a nuclear disaster no-go zone around the Fukushima plant, and it is unknown when those living in the Yoshima industrial park might be able to return to the town.
Sho Tsukamoto, 29, an employee of a construction company who lost his residence and his possessions in the fire, said, “I even lost the picture of my dead father and other photos of my family that I brought from Okuma.”

Nuclear authority method may underestimate quake sizes: study
This May 2016 photo shows the stone wall of Kumamoto Castle that was damaged by the April earthquake.
A technique that estimates the scale of earthquakes announced by the Earthquake Research Committee in 2006 may be underestimating the size of earthquakes — a problem for the Nuclear Regulation Authority, which bases its earthquake resistance plans on the system.
Professor Kazuki Koketsu presented the results of his evaluation of the 2006 system at a research session of The Seismological Society of Japan on Oct. 5. Koketsu is a professor at the Earthquake Research Institute at The University of Tokyo and the head of the Subcommittee for Evaluation of Strong Ground Motion, part of the Earthquake Research Committee.
Koketsu compared the estimations of the 2006 technique and a 2009 method to the actual observed data from the magnitude 7.3 Kumamoto Earthquake in April.
While the 2009 technique predicted a magnitude of 7.0 to 7.2 for the active fault, the 2006 technique underestimated the possible magnitude as between 6.6 and 6.9. Koketsu concluded that the 2009 technique is more appropriate for estimating the scale of earthquakes.
However, the Nuclear Regulation Authority (NRA) still uses the estimates of the strongest possible tremor made by the 2006 system as the basis for examining earthquake resistance design plans for nuclear reactors.
In response to Koketsu’s presentation, a representative of the NRA stated at a press conference held on Oct. 5., “We will begin discussion over whether we should adopt the 2009 system after the Subcommittee for Evaluation of Strong Ground Motion has coordinated its views on the matter.”
The 2006 technique bases its estimates on both the estimated length and breadth of active faults. In 2009, the Earthquake Research Committee released a new system based mainly on the length of faults in order to calculate the expected magnitude of quakes on as many active faults as possible in a short amount of time. In Koketsu’s study, the 2006 system miscalculated the length and width of the faults involved in the Kumamoto earthquake, leading to the underestimation of the scale.
While both techniques appear side by side in the research committee’s manual, the committee’s national earthquake scale prediction map for quakes measuring at least lower-6 on the 7-point Japanese intensity scale estimated to occur within the next 30 years along active faults are all calculated using the 2009 system.

Ban on food from Japan’s radiation-affected areas remains: Taiwan FDA
Taipei, Oct. 6 (CNA) The food and Drug Administration (FDA) reaffirmed Thursday that there is no timetable for any lifting of a ban on food imports from five Japanese prefectures that were affected by radiation fallout from a nuclear power plant meltdown following the 2011 earthquake and tsunami.
“There is no timetable for any such opening,” FDA Director-General Chiang Yu-mei (姜郁美) told CNA.
She declined to comment on reports that Taiwan and Japan have reached an initial consensus on Taiwan’s opening to food imports from the five prefectures.
Taiwan banned food imports from Fukushima, Ibaraki, Tochigi, Gunma and Chiba prefectures in the wake of the meltdown of the Fukushima Daiichi Nuclear Power Plant on March 11, 2011.
FDA Deputy Director-General Lin King-fu (林金富) said that food safety remains the primary concern, adding that the FDA will take stock of the management measures of other countries and continue to assess the situation.
Japanese media reported in May that Taiwan was planning to reopen to food imports from the five prefectures, but the reports were denied by the FDA. Reports resurfaced Thursday again about a lifting of the ban, and that formal opening could come early next year.
However, Pan Chih-kuan (潘志寬), an FDA food section chief, said that no related instructions have been received and that the assessment on Japanese food is still underway.
He stressed the three premises for opening — results of border inspection, monitoring results in Japan and the public’s attitude toward opening.
He said that since 2011, border inspections on 92,000 Japanese food items have been carried out, with 215 items found to contain a tiny amount of cesium. One item was found to contain the radioactive material in the past year.

Fukushima FAQ: Are Fukushima Radionuclides Causing Super Storms in the Pacific and Atlantic?
Hurricane Matthew spins in the Caribbean. Storms are fueled by energy which ultimately comes from the sun.
Short answer is absolutely not.
This post is part of an ongoing series dedicated to science education and to relate scientific findings about the impact of the Fukushima nuclear disaster on environmental and public health. I am frequently (more than you might think) asked if or told that the decay energy from radionuclides released from Fukushima Daiichi are fueling some of the massive cyclones in the Pacific in Atlantic Oceans. This is nonsense of course but highlights some of the logic used and how misinformation can fuel incorrect conclusions with respect to Fukushima and its environmental and public health impacts.
The thought process that brings one to link Fukushima contamination to hurricanes and typhoons goes something like this:
- Fukushima released radionuclides to the environment with much of the contamination ending up in the Pacific Ocean
- Radioisotopes generate heat when they decay
- Tropical cyclones feed off of ocean heat
- Fukushima is causing or causing more intense tropical cyclones
It is likely that increasing sea surface temperatures have the potential to influence the number and intensity of tropical cyclones. However, when we examine the reasoning linking Fukushima to cyclones and add a bit of numeracy we see how this reasoning is flawed.
One of the highest activity isotopes from Fukushima remaining in open ocean surface water is Cesium-137 (half-life = ~30 years, 137Cs). Much of this contamination remains in the North Pacific rather than in the tropics where typhoons form and far away from the tropical Atlantic where hurricanes form but lets ignore this fact for the purpose of our calculation. Maximum 137Cs activities measured by the Fukushima InFORM project in the northeast Pacific are ~ 10 Bq m-3 (cubic meter = 1000 L or ~1000 kg) of seawater.
By knowing this activity and the half-life of the isotope we can calculate the mass of 137Cs in one ton of seawater to be equal to be 0.0000000000031 grams or 3.1 x 10-12 g or 3.1 picograms. This highlights why detecting such low levels of contamination in the ocean is such an analytical challenge.
Now that we know how much 137Cs we have we can look up the decay energy of this isotope as well. This energy corresponds to the difference in mass between the parent and daughter isotope and for 137Cs is equal to 0.6 Watts per gram or 0.6 W g-1 (where a Watt is equal to 1 Joule per second).
So to a first order the power added to one ton (1000 kg) of seawater from Fukushima contamination is about:
(3.1 x 10-12 g) x (0.6 W g-1) = 0.000000000002 Watts or 2 picoW
This is a very small amount of power indeed. We can compare this to the Watts added to a square meter of the ocean surface. Erring on the low side in order to be conservative lets say that the Sun adds about 100 W per square meter (W m-2) at the ocean surface (but see this link from NASA for actual data).
The ratio of the power contributed by the Sun at the ocean surface to Fukushima decay energy is 50,000,000,000,000.
Suggesting that Fukushima energy is fueling cyclone activity is, scientifically speaking, silly. Friends don’t let friends do it.
Please see the NASA website for a useful summary of how tropical cyclones are formed.
