How US and China’s African nuclear mission could provide model for disarming North KoreaSC
- The recent joint operation to remove uranium from Nigeria could provide a template for denuclearisation on the Korean peninsula
- Although the two countries have proved they can still work together, the challenges posed by North Korea are likely to prove far more challenging
This week it emerged that Chinese and American nuclear experts had cooperated on a project to remove highly enriched uranium (HEU) from a reactor in Nigeria to prevent the material falling into the hands of terrorists.
The mission last year, which also involved British and Norwegian experts along with contractors from Russia and the Czech Republic, was completed within a day despite violent clashes in Kaduna province where the reactor was located, according to Defensenews.com.
US and China team up to keep nuclear material from terrorists
The Nigerian operation was not the first time the two countries had worked together to prevent nuclear proliferation in West Africa; a similar operation to remove HEU to China was carried out in Ghana in 2017.
Miles Pomper, a senior fellow at the James Martin centre for non-proliferation studies at the Middlebury Institute of International Studies at Monterey, said: “It is conceivable in the case of denuclearisation that North Korea’s nuclear weapons or material could be taken to China.
“Given the fact that China already has nuclear weapons, the US could likely accept that although the US would likely then push for their disassembly.”
Bruce Bennett, a senior defence researcher at the Rand Corporation, said the two countries would continue to cooperate on dismantling nuclear weapons.
“If instability developed in North Korea, China may well be at greater risk from terrorists or Chinese dissident groups seizing North Korean nuclear weapons and using them against China,” he said……… https://www.scmp.com/news/china/diplomacy/article/2182564/how-us-and-chinas-african-nuclear-mission-could-provide-model
Time to retire Japan’s aging nuclear reactor at Genkai
Decision looms on aging nuclear reactor at Genkai https://www3.nhk.or.jp/nhkworld/en/news/20190117_34/ The operator of a nuclear power plant in western Japan says it plans to decide early this year whether to scrap one of the plant’s reactors, or extend its life.
On Thursday, Kyushu Electric Power Company President Kazuhiro Ikebe revealed the plan during a meeting with the governor of Saga Prefecture that hosts the Genkai plant.
Ikebe said his firm is looking into technical aspects of the plan, including whether the aging reactor could meet the stricter regulations introduced after the March 2011 nuclear accident.
The No.2 reactor at Genkai will turn 40 years old in March 2021. It has been offline since January 2011.
Post-disaster guidelines limit the operation of reactors to 40 years in principle, but allow extensions of up to 20 years with approval of the nuclear regulation authority.
Governor Yoshinori Yamaguchi told Ikebe that he hopes society will reduce its dependence on nuclear energy and eventually be nuclear-free.
Yamaguchi said the utility must understand that the decision it takes will come under public scrutiny.
Kyushu Electric put Genkai’s No.3 and No.4 reactors back online last year, but decided to decommission the No.1 reactor.
If the utility wants to extend the operation of the No.2 reactor, it must file an application with the government by March next year and take additional safety measures.
Locals to go to court against public hearing for jetty near nuclear plant
https://www.thehindu.com/news/cities/mumbai/locals-to-go-to-court-against-public-hearing-for-jetty-near-nuclear-plant/article26044843.ece Alok Deshpande, MUMBAI, JANUARY 21, 2019 As the district administration went ahead with the public hearing for building a jetty next to the proposed 9,900 MW Jaitapur Nuclear Power Plant (JNPP) despite instructions against it from the State Environment minister and adverse reports from research institutes, locals have decided to approach the court and the Centre.
I Log Ports Private Limited has proposed developing a jetty at Nate village in Rajapur taluka of Ratnagiri, next to the site selected for the JNPP. The Hindu on Saturday reported that the Bombay Natural History Society (BNHS) in its letter to the Maharashtra Pollution Control Board pointed out that proposed jetty violates conditions stipulated in the clearance for the JNPP. Senior Shiv Sena leader and Environment minister Ramdas Kadam also wrote a letter to Ratnagiri collector Sunil Chavan to not conduct the public hearing on Saturday.
On Saturday, the hearing was conducted amid opposition from locals. District authorities said, they were asked to register their objections but no one came forward.
Satyajit Chavan, convener, Konkan Vinashkari Prakalp Virodhi Samiti, said the public hearing was illegal and unconstitutional. “The hearing shouldn’t have been held as there are legitimate questions against the environment impact assessment report. This project is against the very principle of clearance given to nuclear plant and the minister himself had ordered not to hold the hearing,” he said. There was no question of submitting objection in an illegally-held public hearing. “It was done at the behest of a private company and is unjustified for locals.”
In his letter, BNHS director Deepak Apte said that the proposed captive jetty is against the very principle of the JNPP clearance. The letter also said that Terms of Reference have not been fulfilled and so the project warrants out right rejection, making the public hearing untenable.
Hiroaki Nakanishi, chairman of the Japan Business Federation gave a gloomy view of nuclear power’s future
Hitachi chief’s remarks on nuclear industry spark debate, Japan Times, BY PHILIP BRASOR , 20 Jan 19, On Jan. 1, Hiroaki Nakanishi, chairman of the Japan Business Federation (Keidanren), held press interviews on the outlook of the business community and, at one point, the discussion turned to nuclear energy.
Nakanishi is also the chairman of Hitachi Ltd., a major supplier of nuclear technology, and he said that the commercial possibilities for nuclear energy in Japan, for both “clients,” meaning power companies, and “vendors,” meaning plant manufacturers such as Hitachi, were increasingly limited. If clients can’t make a profit, then neither can vendors, and that will continue to be the case as long as the public is opposed to nuclear energy. The industry can’t force nuclear power on the citizens of a democracy.
Major media were presumably represented at the interviews, but only one outlet, All-Nippon News Network (ANN), reported Nakanishi’s nuclear-related comments. Jan. 1 was a newspaper holiday, which means that no newspapers were published on Jan. 2, but there was still no other mention of his remarks on Jan. 3. On Jan. 5, journalist Hajime Takano commented on this lack of interest to former Prime Minister Yukio Hatoyama on the latter’s web channel for his East Asian Community Institute. The head of Hitachi, a key company in nuclear technology, had said that the business of nuclear energy is impossible without public support. Since nuclear energy is national policy, the ramifications are huge, Takano said, and yet no other major media had covered the remarks or ANN’s report. Were they afraid of upsetting the government?
As Takano pointed out, the Tokyo Shimbun, which as a regional newspaper doesn’t qualify as “major media” and tends to question the government’s nuclear policy, did mention Nakanishi’s remarks on its front page on Jan. 5, suggesting that the Hitachi chairman was no longer aligned with the administration on nuclear energy. Almost eight years after the disaster at the Fukushima No. 1 nuclear power plant, no nuclear plants in eastern Japan have resumed operation and, without an economic rationale for nuclear power, the policy is pointless.
But the Tokyo Shimbun also reported that Nakanishi said Japan does not have the right environment for renewable energy. This qualification seemed to imply that nuclear power was still preferable, but only if the public could be persuaded to accept it. So while part of Nakanishi’s remarks might give the impression that Japan’s nuclear power industry is throwing in the towel, they need to be contextualized within the larger picture of Hitachi’s business.
……… Ever since Japanese nuclear plant expansion ground to a halt after the Fukushima disaster, the government has promoted overseas nuclear development as a growth strategy, with Prime Minister Shinzo Abe as the lead international salesman. However, proposed projects in Vietnam, Taiwan and other places have stalled one after another. The collapse of the British project, which was formally announced Thursday, may be the final nail in the coffin.
In that light, Nakanishi’s new year remarks sound fatalistic, but pundits hear something different. Nikkan Gendai interviewed former trade ministry official Shigeaki Koga, who pointed out that Japan’s nuclear energy players are dependent on the government. Without support, there was no way private power companies or vendors could have made money on nuclear energy. They essentially stuck with it because it was national policy. Nakanishi’s remarks, Koga said, were really veiled threats directed at the government: If you don’t help us financially and legally, then we will have no choice but to get out of the nuclear business. If you want us to continue, he added, it’s your job to convince the public that nuclear energy is worth it………. https://www.japantimes.co.jp/news/2019/01/19/national/media-national/hitachi-chiefs-remarks-nuclear-industry-spark-debate/#.XETXadIzbGg

Nagasaki: Life after Nuclear War – the past and the future
Ground Zero Nagasaki: Living the nuclear past – and future, Asia Times, By SUSAN SOUTHARD JANUARY 18, 2019 “………. Much of Nagasaki and the world have, of course, moved on from that terrible morning when a 5-ton plutonium bomb plunged at a thousand kilometers an hour toward the city of 240,000 people. Forty-three seconds later, it detonated half a kilometer above Nagasaki’s Urakami Valley. A super-brilliant blue-white flash lit the sky, followed by a thunderous explosion equal to the power of 21,000 tons of TNT. The entire city convulsed
Based on my book Nagasaki: Life after Nuclear War, I often give talks in the US about that unforgettable (or now often-too-forgettable) day when, for only the second time in history, human beings deemed it right to assault their own species with apocalyptic power. At these book talks, I’ve learned to be prepared for someone in the audience to say that the Japanese deserved what they got. It’s still hard to hear.
At its “burst point,” the Nagasaki blast reached temperatures higher than at the center of the sun, and the velocity of its shock wave exceeded the speed of sound. Within three seconds, the ground below had reached an estimated 3,000 to 4,000 degrees Celsius. Directly beneath the bomb, infrared heat rays instantly carbonized human and animal flesh and vaporized internal organs. Did the men, women, and children of Nagasaki really deserve that?
As the mushroom cloud rapidly ascended 3km over the city and eclipsed the sun, the bomb’s vertical blast pressure crushed much of the Urakami Valley. Horizontal blast winds tore through the region at two and a half times the speed of a Category 5 hurricane, pulverizing buildings, trees, animals, and thousands of people.
The blazing heat twisted iron, disintegrated vegetation, ignited clothing, and melted human skin. Fires broke out across the city, burning thousands of civilians alive.
And though no one knew it yet, larger doses of radiation than any human had ever received penetrated deeply into the bodies of people and animals.
…………. the United States bombed and incinerated all or parts of 66 Japanese cities, killing, maiming or irradiating more than 668,000 civilians. In Nagasaki alone, by the end of 1945 when a first count was possible, 74,000 men, women and children were dead. Of those, only 150 were military personnel. Seventy-five thousand more civilians were injured or irradiated.
Today, this kind of indiscriminate killing and harm to civilians would be called “terrorism.”
Despite the history most Americans have learned – that the atomic bombings of Hiroshima and Nagasaki were military necessities that ended World War II and saved a million American lives by obviating the need for an invasion of Japan’s home islands – there is no historical evidence that the Nagasaki bombing had any impact on Japan’s decision to surrender.
What we aren’t taught are the political and military complexities of the last few months of the war or how, in the postwar years, the US government crafted this end-of-war narrative to silence public opposition to the atomic bombings and build support for America’s fast-expanding nuclear-weapons program.
What many don’t realize is that this misleading version of history allows us to turn away from what happened in Hiroshima and Nagasaki and continue to support the development and proliferation of nuclear weapons without ever having to think about what those weapons do.
Still, so many decades later, in a world in which the Trump administration is preparing to withdraw from a key Cold War nuclear agreement with Russia and the US nuclear arsenal is being modernized to the tune of up to $1.6 trillion, it’s worth recalling the other side of the story, the kind of suffering the Hiroshima and Nagasaki bombings caused in August 1945 and long after.
Within weeks, people in both cities began experiencing mysterious symptoms: vomiting, fever, dizziness, bleeding gums, and hair loss from what doctors would later understand as radiation-related sickness. Purple spots appeared all over their bodies. Many died in excruciating pain within a week of the first appearance of such symptoms. Fear gripped Nagasaki. From one day to the next, no one knew when his or her time might come.
In those first nine months, pregnant women suffered spontaneous abortions, stillbirths, or the deaths of their newborn infants. Many of the babies who survived would later develop physical and mental disabilities.
Five years after the bombings, thousands more began dying from leukemia and other illnesses caused by high-dose radiation exposure, initiating cycles of higher than normal cancer rates that would last for decades. The bombs had, from the survivors’ perspective, burned their bodies from the inside out. Parents exposed to radiation feared possible genetic defects in their children and hovered over them year after year, terrified that what looked like a simple cold or stomach ache would lead to severe illness or death.
Even today, radiation scientists are still studying second- and third-generation hibakusha (atomic-bomb-affected people) for genetic effects passed down from their parents and grandparents, reminding us how much we still don’t understand about the insidious nature of radiation exposure to the human body…….. http://www.atimes.com/ground-zero-nagasaki-living-the-nuclear-past-and-future/
Top North Korea envoy meets Trump at White House for nuclear talks
Straits Times, WASHINGTON (REUTERS) 18 Jan 19, – A top North Korean nuclear envoy met President Donald Trump at the White House after holding talks with Secretary of State Mike Pompeo on Friday (Jan 18) in a diplomatic flurry aimed at laying the groundwork for a second US-North Korea summit.
The visit of Kim Yong Chol, Pyongyang’s lead negotiator with the United States and a hardline former spy chief, marked a rare sign of potential movement in a denuclearisation effort that has stalled since a landmark meeting between Trump and North Korean leader Kim Jong Un in Singapore last year.
Kim Yong Chol and Pompeo, with tight smiles, posed together for photographs at a Washington hotel before holding about 45 minutes of talks that could help determine whether the two sides can make headway.
After that meeting, the White House said Trump hosted Kim Yong Chol in the Oval Office to “discuss relations between the two countries and continued progress on North Korea’s final, fully verified denuclearisation.”
There has been no indication of any narrowing of differences over US demands that North Korea abandon a nuclear weapons programme that threatens the United States or over Pyongyang’s demand for a lifting of punishing sanctions.
Hours before Kim Yong Chol’s arrival on Thursday, Trump – who declared after the Singapore summit in June that the nuclear threat posed by North Korea was over – unveiled a revamped US missile defence strategy that singled out the country as an ongoing and “extraordinary threat.”
The State Department said after Friday’s meeting that Pompeo had a “good discussion” with Kim Yong Chol “on efforts to make progress on commitments President Trump and Chairman Kim Jong Un made at their summit in Singapore.”
But it provided no specifics.
The high-level visit could yield an announcement of plans for a second summit. Both Trump and Kim have expressed an interest in arranging but some US-based analysts say it would be premature due to the lack of obvious progress so far………. https://www.straitstimes.com/world/united-states/north-korea-envoy-in-us-for-talks-with-secretary-of-states-mike-pompeo-possibly
Pentagon report on China’s nuclear weapons program, still “significantly below” the U.S.
The Pentagon Believes China Is Likely Developing A Long-Range Nuclear Bomber, Task and Purpose, Tony Capaccio, Bloomberg News, January 17, 2019 WASHINGTON — China is likely developing a long-range bomber capable of delivering nuclear weapons and a space-based early warning system it could use to more quickly respond to an attack, according to a new report from the U.S. Defense Intelligence Agency.
The development of the bomber, when combined with China’s land-based nuclear weapons program and a deployed submarine with intercontinental ballistic missile technology, would give Beijing a “triad” of nuclear delivery systems similar to the U.S. and Russia, according to the report published Tuesday.
“China is building a robust, lethal force with capabilities spanning the air, maritime, space and information domains which will enable China to impose its will in the region,” the report’s author, Lt. Gen. Robert Ashley, said in the introduction.
The report comes as President Donald Trump’s administration focuses on the potential for “great power” conflict with countries like China and Russia as part of its national defense strategy. It also comes amid heightened trade tensions between Washington and Beijing, and continuing disputes about China’s posture in the South China Sea.
……… The DIA assessment released Tuesday underscores that China maintains a “no first-use” nuclear policy but adds that there is “some ambiguity, however, over the conditions under which China’s NFU policy would apply.”
Despite a slew of disputes over Taiwan, the South China Sea and global trade, the review also says there is no indication in Chinese military strategic documents that Beijing views war with the U.S. as looming.
Moreover, while China’s defense spending climbed an average of 10 percent per year from 2000 to 2016, total spending remains “significantly below” the U.S., the report said. Spending was about 1.3 percent of gross domestic product from 2014-2018, compared to more than 3 percent of GDP for the U.S. over the same period.
China is trying to strike a balance between expanding its capabilities and reach without “alarming the international community about China’s rise or provoking the United States, its allies and partners, or others in the Asia-Pacific region into military conflict or an anti-China coalition,” the report adds.
Underlying China’s concerns are its view that the U.S.-led security architecture in Asia seeks to constrain its rise and interfere with its sovereignty, particularly in a Taiwan conflict scenario and in the East and South China Seas, said DIA.
The DIA’s observations will likely be used by proponents of the Pentagon’s drive to modernize the U.S. aging nuclear weapons infrastructure over 30 years, an effort that, when operations and support costs are included, could total about $1 trillion………. https://taskandpurpose.com/the-pentagon-believes-china-is-likely-developing-a-long-range-nuclear-bomber
Concerns about safety of China’s planned 46 nuclear reactors within a radius of about 100 km from Hong Kong and Macau.
![]()
China’s Guangdong to have 26 nuclear reactors, Indigenous Hualong reactors to be built at new megaplant in Huizhou, JANUARY 17, 2019 China’s southern Guangdong province is on a spree constructing nuclear power plants, with the latest addition to the province’s nuclear plant cluster in the city of Huizhou, 90 kilometers northeast of Hong Kong…..
The 120 billion yuan (US$17.74 billion) megaproject, to be run by the state-owned China General Nuclear Power Corp (CGN), will bring the total number of nuclear reactors in Guangdong, a manufacturing powerhouse and China’s largest provincial economy, to 26.
CGN’s ultimate plan is to boost that number to 46, spanning 11 plants, to power Guangdong’s booming economy, whose gross domestic product in 2018 is tipped to hit the 10-trillion-yuan mark and surpass South Korea and Canada.
The new reactors in Huizhou, already given the go-ahead by China’s environmental watchdog, will be built around China’s indigenous, third generation Hualong (China Dragon) pressurized water nuclear reactor ……..
The first Hualong reactor went live in Fujian province in 2017.
Still, concerns are being raised about the safety of so many nuclear plants, including Daya Bay, Ling’ao, Taishan, Lufeng, Yangjiang and Huizhou, within a radius of about 100 km from Hong Kong and Macau.
Guangdong’s aggressive plans to harness nuclear energy have long stoked fears about safe operations and the disposal of spent fuel rods.
CGN has sought to allay misgivings by promising more transparent consultation, reactor management and notification of incidents, but the company has given scant information about the Huizhou plant, the built-in safety infrastructure and contingency plans.
The company told Xinhua that the National Nuclear Safety Administration would conduct a further assessment of the plant’s design and safety facilities and decide the start of its construction. http://www.atimes.com/article/chinas-guangdong-to-have-26-nuclear-reactors/
Missile Defense Review: North Korea remains ‘extraordinary threat’ to US

High radiation levels in Fukushima area, but the Japanese government is pushing people back there
Fukushima Residents Return Despite Radiation, Eight years after the nuclear meltdown, wary citizens are moving back to contaminated homesteads—some not by choice, Scientific American, By Jane Braxton Little January 16, 2019
When the Fukushima Daiichi Nuclear Power Plant began spewing radioactive particles after it was clobbered by a tsunami in March 2011Kaori Sakuma fled. She bundled her infant and toddler into a car and left her husband and family in Koriyama, 44 miles west of the ruptured facility. “The truth is, I ran away,” she says. Confronting gas shortages and snarled roads, she transported her children 560 miles away to Hokkaido, about as far as she could get.
Radiation from the fuming plant spread over tile-roofed towns and rice paddies across an area the size of Connecticut. The meltdown 150 miles north of Tokyo drove more than 200,000 people out of the region. Most believed they were fleeing for their lives. Now, almost eight years after the accident, the government has lifted most evacuation orders. Nearly 122,000 people have been allowed to return to communities where weeds have overtaken parking lots. Most are elderly, relieved to be resuming their lives. Prime Minister Shinzo Abe is determined to end all evacuations by 2020, when Japan will host the Olympic Summer Games. The events will include baseball and softball competitions in Fukushima City, a mere 55 miles from the ruined reactors.
Around 35,000 other citizens still wait to return, but they and many others throughout northeastern Japan worry all of this is too soon. Radiation, which is generally linked to cancer, in some places continues to measure at least 5 millisieverts (mSv) a year beyond natural background radiation, five times the added level Japan had recommended for the general public prior to the incident. In certain spots radioactivity is as high as 20 mSv, the maximum exposure recommended by international safety experts for nuclear power workers.
In its haste to address the emergency, two months after the accident the Japanese government raised the allowable exposure from 1 mSv annually, an international benchmark, to 20 mSv. Evacuees now fear Abe’s determination to put the Daiichi accident behind the nation is jeopardizing public health, especially among children, who are more susceptible. Lifting most evacuations has also ended subsidies for evacuees, forcing many to return despite lingering questions.
As more people inside and outside the country absorb the radiation data, Japanese officials are confronting a collapse of public confidence. Before the accident residents in Japan (and the U.S.) were living with background radiation that averaged 3.1 mSv a year,most of it emanating naturally from the ground and space. In Japan and the U.S. many residents experience an additional 3.1 mSv annually, due mostly to medical testing. But the anxiety of Fukushima residents facing even higher levels is palpable. If the government is going to fully restore lives and livelihoods, it needs to regain their trust, says nuclear engineer Tatsujiro Suzuki, a professor at Nagasaki University and former vice chairman of the Japan Atomic Energy Commission. That, he says, should include respecting international safety standards for radiation and lowering the allowable level at least to 5 mSv, although he acknowledges “even 5 mSv is too high for children.”
……….Concern about children is one of the most controversial issues. When officials raised the allowable level of radiation to 20 mSv, including in schools, it was under the guise of giving people a measure of normalcy. But the May 2011decision became a flash point for opponents of the government’s handling of the accident. They were furious children would be subjected to the maximum radiation allowed for nuclear workers, spending day after day in buildings that increased their cancer risk to one in 200 people.
Sakuma was one of those who returned to Koriyama, from her outpost in Hokkaido. She did not want her young children to touch contaminated soil or water along their walk to school, so she carried them both on her small back. “We all want our kids to play in the dirt and pick flowers but I was afraid. We all were,” says Sakuma, now 46. ……https://www.scientificamerican.com/article/fukushima-residents-return-despite-radiation/
Japanese people losing trust in government, as the Fukushima nuclear catastrophe still poses health risks
Fukushima Residents Return Despite Radiation Eight years after the nuclear meltdown, wary citizens are moving back to contaminated homesteads—some not by choice, SCIENTIFIC AMERICAN, BY JANE BRAXTON LITTLE JANUARY 16, 2019
“………. LACK OF PUBLIC TRUST
In the year after the accident Koriyama was one of 12 communities where the ongoing radiation rate measured between 3 and 5 mSv above background, but the town had not been evacuated. Today’s levels have stabilized at 1.5 mSv, but doubts remain. Skeptical of the government’s readings, Shigeru Otake, 49, takes his own. A slim man who wears a Dollar Store rope belt to give him “strength like a samurai,” he says he has measured radiation spikes at 15 mSv in Koriyama, where his family has lived for generations. Sakuma walks her sons, now eight and 10 years old, to school past a government monitoring post that she claims reads six times lower than her own dosimeter does.
Misgivings about government assurances of safety drove Hiroshi Ueki, 48, to move his family to Nagano Prefecture, where he is now growing “the best grapes in the world.” His parents stayed behind in Fukushima Prefecture. Ueki says he will never move back. “The prime minister says the accident is over but I won’t ever feel safe until the Daiichi plant itself is finally shut down. That will take 100 years.”
In spite of these concerns, Japan has continued to showcase repatriation as a barometer of progress toward recovery. By April 2017, the government had lifted all evacuations except for the most contaminated places closest to Daiichi. That decision also ended rent-free housing provided to people who were forced to leave as well as to some 26,600 people like Ueki who vacated voluntarily. Left without the $10,000 monthly subsidy provided by Tokyo Electric Company, some people have been forced to return home despite their safety concerns. They have no other economic options, says Hajime Matsukubo, general manager of the Citizens’ Nuclear Information Center. Some 16,000 people who refuse to return have been financially abandoned, according to the center.
Scientists generally agree on a few basics: The risks of getting leukemia or other cancers are higher for children than adults, and the risks for everyone increase significantly with exposure above 100 mSv annually. Various national agencies have set 20 mSv per year as a maximum for occupational exposure. Public exposure should be no more than 1 mSv per year above background levels, according to the International Commission for Radiological Protection. That raises questions about Japan’s 2011 emergency declaration of 20 mSv per year as the allowable exposure. …….
The public perception is that the Daiichi nuclear accident continues to pose health risks and, significantly, nuclear power is not safe. More than 80 percent of the Japanese public wants to phase it out, according to an October 2018 study by Suzuki, the former Japan Atomic Energy commissioner. He calls the erosion of public trust “the most unfortunate impact of the accident.”
Sakuma, the Koriyama mother, is using the Daiichi accident as a lesson in radical civic involvement. She intends to keep her sons in Koriyama despite radiation concerns. “I want them to grow up here so they can learn what the government does. I want them to tell other people about how it is to live with radiation,” she says. “This accident is not over.” https://www.scientificamerican.com/article/fukushima-residents-return-despite-radiation/
