There are “positive signals” on Korean Peninsula nuclear issue – China

China hails “positive signals” on Korean Peninsula nuclear issue http://news.xinhuanet.com/english/2017-06/23/c_136389835.htm Editor: Mengjie BEIJING, June 23 (Xinhua) — China on Friday hailed recent “positive signals” on the Korean Peninsula nuclear issue and called for addressing concerns of various parties in a balanced way.

Chinese Foreign Ministry spokesperson Geng Shuang made the comments in response to a question regarding remarks by a number of diplomats concerned about the issue.

The Democratic People’s Republic of Korea (DPRK) ambassador to India Kye Chun Yong said Wednesday the DPRK would not rule out suspending nuclear and missile tests if the United States abandoned the practice of holding large-scale military drills, according to media reports. The ambassador said Pyongyang was ready for negotiations with the United States at any time and without preconditions.

Meanwhile, a special advisor to President Moon Jae-in of the Republic of Korea (ROK) indicated a reduction of joint war games with the United States if the DPRK stopped nuclear and missile activities.

“China believes these positive messages are important for easing tension on the peninsula and for a solution to the issue through dialogue,” Geng said. Geng said the root of the Korean Peninsula nuclear issue was in security. He said the solution required comprehensive measures and addressing both the symptoms and root causes.

China proposed a “dual-track approach” to denuclearization on the Korean Peninsula, establishing a peace mechanism in parallel, and a “suspension for suspension” to defuse the looming crisis.

As a first step, Pyongyang may suspend its nuclear and missile activities in exchange for the suspension of large-scale Washington-Seoul military exercises.

China has also called for strengthening efforts on non-proliferation and promotion of peace talks to bring the nuclear issue on the Korean Peninsula to a peaceful settlement.

“We are glad to see China’s proposals have gained increasing support and responses,” Geng said.

China welcomes and encourages suggestions to help alleviate tension and confrontation, enhance communication and trust, and restart dialogue as soon as possible, Geng said.

He called for the international community to seize all possible opportunities, to promote the settlement of the issue through dialogue and consultations.

Students and researchers at research reactors should have background checks, warns Japan’s nuclear regulator

NRA urging background checks on students using Japan’s research reactors, Japan Times, 23 June 17 KYODO Japan’s nuclear regulator has urged universities to conduct background checks on students and researchers working at research reactors, as a step to ensure the proper handling of nuclear materials and prevent terrorism, a source said Thursday.

The check items include mental disorder and criminal records and those who have access to strictly controlled nuclear material storage areas at research reactors owned by universities will be subject to the new rule.

But the decision will likely raise concerns about privacy and human rights, legal experts say. University officials are concerned that the inquiries could also discourage students from becoming researchers in the nuclear industry.

The Nuclear Regulation Authority’s request comes after the International Atomic Energy Agency recommended the Japanese government conduct background checks on workers at nuclear power plants and those involved in decommissioning work at the Fukushima No. 1 nuclear power plant, crippled by the 2011 earthquake and tsunami.

Based on the recommendation, the nuclear safety watchdog decided last year to conduct background checks on workers at nuclear plants. Plant operators plan to start the checks as early as this fall.

A total of 17 check items also include students’ and researchers’ names, nationalities, employment history and addiction to alcohol, the source said……..http://www.japantimes.co.jp/news/2017/06/23/national/nra-urging-background-checks-students-using-japans-research-reactors/#.WU14LpKGPGg

Vulnerable to Climate Change – Bangladesh

From heatwaves to hurricanes, floods to famine: seven climate change hotspots  Global warming will not affect everyone equally. Here we look at seven key regions to see how each is tackling the consequences of climate change, Guardian, John Vidal, 23 June 17

“….Dhaka, Bangladesh

I met Honufa soon after she arrived in Dhaka 10 years ago. Erosion and saltwater intrusion on her family’s land on one of the low-lying islands in the mouth of the Ganges River had forced the young Bangladeshi woman to leave her village for the capital. She had taken a boat and then an overnight bus and ended up in a slum called Beribadh.

Honufa is a climate refugee, one of thousands who have struggled to grow their crops. Millions are likely to follow her if current trends continue.

“In the next 20 years we would expect five to 10 million people to have to move from the coastal areas,” says Saleemul Huq, director of the Bangladesh-based International Centre for Climate Change and Development. “The whole country is a climate hotspot, but the most vulnerable area is the coast. Dhaka is the place where people head to,” he says.

Huq, who has advised the Bangladesh government at successive UN climate summits, says there is strong evidence that climate change is now impacting Dhaka. “Temperatures have already gone up by 1C. We can see that the weather patterns have changed. Ask anyone in the street, and they will say the frequency of floods has changed. Bangladesh has a long history of floods, but what used to be a one-in-20-year event now happens one year in five. It is what we would expect with climate change models.”

Huq and other Bangladeshi climate scientists expect to see more extremes. “Changing rain patterns suggest we will not get more rain over the coming years but it will be distributed differently, with less in the dry season and more during the monsoons. Paradoxically, this will lead to more floods and droughts, and heavier monsoons,” he says.

“We are beginning to see sea levels rising and increased salinity in coastal areas. It is a slow onset, which will get worse. It is a climate change phenomenon and not something we had before.”

Huq leads research into how Bangladesh can adapt to climate change. “We’ve done a lot of research looking at the most vulnerable hotspots. We are learning by doing,” he says. “Government has now invested in a major climate change action plan. To counter coastal salinity there is a big program of rainwater harvesting and coastal protection. Scientists are developing saline-tolerant rice. People and government are proactive.

“The trouble is that we are always catching up with the problem. There is a limit to what we can grow. At some point we will run out of options, then people will have to move. We know that if we don’t take action people will all end up in Dhaka, so [we] need to invest in other towns and cities.”….https://www.theguardian.com/environment/2017/jun/23/from-heatwaves-to-hurricanes-floods-to-famine-seven-climate-change-hotspots?CMP=share_btn_tw

India gives up on importing Western nuclear reactors, to save face, will build its own.

India’s inward nuclear turn, ECONOMIC TIMES,  JUN 22, 2017, By Brahma Chellaney Just as Japan’s Diet has ratified the civil nuclear agreement with New Delhi, India has decided to build 10 nuclear power reactors of indigenous design in what is the largest such construction decision in the world since the 2011 Fukushima nuclear disaster. India’s turn to a “fully home-grown initiative“ reflects the continuing problems in implementing the 2005 Indo-US nuclear deal.

Plutonium in Workers’ Urine


The Asahi Shimbun is reporting that, contrary to the reassurances made a few days ago by the Japan Atomic Energy Agency (see here), workers at JAEA’s Oarai Research and Development Center, WERE internally contaminated by Plutonium:

Plutonium found in urine of 5 workers in Ibaraki accident. THE ASAHI SHIMBUN, June 20, 2017 http://www.asahi.com/ajw/articles/AJ201706200039.html

Minute amounts of plutonium have been detected in the urine samples of all five workers who were accidentally exposed to radioactive plutonium at Japan Atomic Energy Agency (JAEA)’s Oarai Research and Development Center in Oarai, Ibaraki Prefecture, on June 6…. While maintaining the level of exposure the five workers experienced “would not have immediate effect on their health for a few months,” Akashi said their internal exposure levels are “relatively high for cases occurring in Japan as far as I know.”… 

…In urine testing, NIRS said it can detect smaller amounts of plutonium as the measurement time is much longer, while the smallest radiation doses the dosimeter for lungs can detect is between 5,000 and 10,000 bequerels.

I shouldn’t be too critical of these oscillating reports given the US won’t even admit when its workers are contaminated with Plutonium, as the recent tunnel collapse at Hanford reminds us:

Tia Ghose. May 10, 2017. Hanford Disaster: What Happens to Someone Who’s Exposed to Plutonium? Live Science, https://www.livescience.com/59042-how-does-plutonium-damage-the-body.html

Workers at a nuclear-waste site in Washington state were recently told to hunker down in place after a tunnel in the nuclear finishing plant collapsed, news sources reported yesterday (May 9)…

The tunnel was part of the plutonium and uranium extraction facility (PUREX) said to be holding a lot of radioactive waste, including railway cars used to carry spent nuclear fuel rods, news agency AFP reported. At least some of the radioactive waste at the Hanford facility contains radioactive plutonium and uranium, according to the DOE, although at least some of it is also radioactive “sludge” composed of a mixture of radioactive substances. Right now, authorities have not revealed whether radioactive substances have been released or whether people have been exposed any of these contaminants

Governments don’t want to talk too much to the public about plutonium. Every dimension of knowledge about this element seems to be weaponized. Despite the desire for secrecy, plutonium always seems to be out of bounds, contaminating some people or environment, or perhaps all people, especially men’s testes (see here).

Plutonium’s astonishing level of chemical toxicity and atomic instability are fetishized by the atomic priesthood, but the priesthood cannot control their Frankensteinan creation, as these stories and ongoing atmospheric emissions at Fukushima Daiichi demonstrate:

Plutonium in workers’ urine at Oarai Research and Development Center

plutonium oarai 20 juin 2017.jpg

Traces of plutonium in workers’ urine

Doctors say extremely small quantities of radioactive substances have been detected in the urine of 5 workers who were accidentally exposed to the materials early this month at a research facility north of Tokyo.

The incident took place on June 6th at a facility of the Japan Atomic Energy Agency in Oarai Town, Ibaraki Prefecture. The workers were inspecting a nuclear fuel container when a bag inside suddenly burst, expelling radioactive powder.

The agency initially said as much as 22,000 becquerels of plutonium-239 were detected in the lungs of one of the workers. But they were discharged from hospital by Tuesday of last week after repeated examinations at the National Institute of Radiological Sciences detected no plutonium in their lungs.

On Monday, the institute said checks of the 5 workers’ urine later revealed extremely small amounts of plutonium and other radioactive materials.

It says the workers have so far suffered no damage to their health, but that they have reentered hospital to take medicines that will purge the plutonium from their bodies. They will take the drug for 5 days, after which doctors will decide if further medication is necessary.

An official related to the institute says the radioactive materials in the workers’ bodies are at levels that will not immediately affect their health.

Meanwhile, the Japan Atomic Energy Agency, which employs the 5 workers, on Monday submitted to the country’s nuclear regulator an interim report on how the accident unfolded.

The agency’s president, Toshio Kodama, told reporters that he apologizes to the public for the incident. Kodama added that his organization may have problems sensing and foreseeing risks.

Kodama said the agency has to work on organizational issues, including worker awareness.

The agency says it plans to conduct a detailed investigation into the cause of the accident. It says it will consider measures to prevent recurrences and report to the regulator.

https://www3.nhk.or.jp/nhkworld/en/news/20170619_27/

Tokyo, June 19 (Jiji Press)–Trace amounts of plutonium have been detected in the urine of all five workers exposed to radioactive materials at a nuclear research facility in eastern Japan earlier this month, a radiological research center treating them said Monday.
 The radioactive substances detected in the urine were plutonium-239, plutonium-238 and americium-241, the National Institute of Radiological Sciences, or NIRS, said.
The results showed that the workers at the Japan Atomic Energy Agency’s Oarai Research and Development Center in Ibaraki Prefecture, northeast of Tokyo,
suffered internal radiation exposure, the NIRS said.
The NIRS plans to continue examining the five workers for about a month to estimate levels of exposure.
   The exposure is unlikely to reach levels that cause symptoms, said Makoto Akashi, a senior official at the National Institutes for Quantum and Radiological Science and Technology, which oversees the NIRS.

Plutonium found in urine of 5 workers in Ibaraki accident

Minute amounts of plutonium have been detected in the urine samples of all five workers who were accidentally exposed to radioactive plutonium at Japan Atomic Energy Agency (JAEA)’s Oarai Research and Development Center in Oarai, Ibaraki Prefecture, on June 6.

The test results were announced June 19 at a news conference by the National Institute of Radiological Sciences (NIRS) within National Institutes for Quantum and Radiological Science and Technology (QST).

The revelation marks the latest twist in the changing assessment of severity of the health risks in the accident. Initially JAEA announced on June 7 that one of the five workers had suffered an internal exposure of 22,000 bequerels during an inspection at the nuclear energy research center. On June 9, JAEA said no plutonium was detected in any of the five workers’ lungs in further testing by NIRS.

Makoto Akashi, an executive of QST, said at the news conference the latest finding confirmed that the workers did “suffer an internal exposure.”

While maintaining the level of exposure the five workers experienced “would not have immediate effect on their health for a few months,” Akashi said their internal exposure levels are “relatively high for cases occurring in Japan as far as I know.”

He also added that long-term observation may be necessary depending on the level of internal exposure.

JAEA’s initial “internal exposure of 22,000 bequerels” assessment was hastily done on the night of the accident on June 6. The five workers were examined using a dosimeter that can detect small traces of X-rays emitted by plutonium particles inhaled into the lungs.

However, the next day, NIRS staff discovered that four of the workers did not have all the plutonium on their bodies completely removed. After thorough decontamination efforts, they were retested for plutonium in the lungs, which was “not detected.”

It is believed the initial assessment came back with a high reading, as the dosimeter also picked up the radiation from the plutonium residue on their bodies.

In urine testing, NIRS said it can detect smaller amounts of plutonium as the measurement time is much longer, while the smallest radiation doses the dosimeter for lungs can detect is between 5,000 and 10,000 bequerels.

The latest test result suggests the possibility that some plutonium particles inhaled into the workers’ lungs have been absorbed into the bloodstream, then discharged into the urine.

The five workers had been discharged and are in stable condition, but were readmitted to the institution for further treatment on June 18. They started receiving medication via intravenous drip injections to speed the excretion of radioactive substances in their bodies from June 19, according to NIRS.

It is the second time they have received this medication. NIRS confirmed the treatment’s effectiveness as the amount of plutonium in their urine increased after the first round of injections compared to the amount found prior to receiving the drug.

South Korea’s major turn away from nuclear energy with Kori-1’s permanent shutdown

 Jun.20,2017 , Changed energy policy prioritizes public safety, in line with South Korea’s turn from developing to developed country

“Permanently shutting down operations at Kori-1 is the beginning of a journey toward a nuclear-free country; it is the turning point toward a safe country. I will soon be preparing a roadmap for the nuclear power phase-out that can set South Koreans’ hearts at ease,” President Moon Jae-in said on June 19. With anxiety increasing around the world about the safety of nuclear power following the nuclear accident in Fukushima, Japan, Moon has become the first South Korean president to declare a nuclear power phase-out, signaling a major change in the country’s energy policy.

“Since South Korea has to import the majority of its energy, nuclear power was the energy policy chosen when we were still a developing country, but now it’s time to change that,” said Moon during an address delivered at a ceremony marking the permanent shutdown of Kori-1. The ceremony took place at the Kori Nuclear Power Headquarters of Korea Hydro & Nuclear Power (KHNP), located in Gijang County, Busan.

Moon’s declaration of the goal of making South Korea nuclear-free signifies his willingness to turn the country’s current energy policy paradigm on its head. It affirms a transition from the energy policy of developing countries, which prioritize cheap power and efficiency, to that of developed countries, which place a premium on the environment and on the people’s right to life.

The key message offered by Moon is “public safety.” While mentioning the earthquake that struck Gyeongju in Sep. 2016, Moon emphasized that South Korea is no longer safe from earthquakes. Citing the fact that 3.82 million people live within a 30 km radius of the Kori plant, he argued that a nuclear accident in South Korea could be even more horrific than what happened at Fukushima

“The world today is moving irreversibly toward phasing out nuclear power. This is something we have to start now on behalf of our descendants, who will live in this country for millennia to come,” Moon said, making clear that it was impossible to return to the energy policy of the past.
Moon’s address also marks the point when he begins to specifically implement the pledges he made as a presidential candidate. He had promised to scrap all plans for building new nuclear reactors, to immediately shut down reactors whose operational life cycle has ended, to suspend construction on Shin Kori-5 and Shin Kori-6, and to shut down Wolseong-1. “It’s as if the people of Busan [who live close to the Kori nuclear plant] have to live with this bomb by their beds that could go off at any time,” Moon said, after watching the nuclear disaster film “Pandora” at the end of last year. “We shouldn’t be asking whether or not to open up Pandora’s box [nuclear power]; we should be getting rid of the box altogether.”“The reason we haven’t been able to phase out nuclear power is not because of a lack of researchers but because of a lack of government will. The fact that the new government has not only shut down the Kori-1 nuclear reactor but also announced a new energy policy and declared its intention to phase out nuclear power in this address is very significant,” said Yun Sun-jin, a professor at the Graduate School of Environmental Studies at Seoul National University.“The next stage is to draw up a detailed roadmap for the nuclear power phase-out. Developed countries are reducing their consumption of electricity. A superficial comparison should be avoided since their industrial structures are different from ours, but in the future, we too should be able to move in the direction of the efficient consumption of energy,” Yun added.By Jung Yu-gyung and Lee Jung-ae, staff reporters

New South Korean president vows to end use of nuclear power

Moon Jae-in said he would lead country towards a ‘nuclear-free era’ following fears of a Fukushima-style meltdown

4967.jpgMoon Jae-in speaks at an event to mark the closure of South Korea’s oldest nuclear plant, Kori-1.

 

South Korea’s new president, Moon Jae-in, has vowed to phase out the country’s dependence on nuclear power, warning of “unimaginable consequences” from a Fukushima-style meltdown.

Moon, a left-leaning liberal who won last month’s presidential election by a landslide following the impeachment and arrest of Park Geun-hye, said he would increase the role of renewable energy and lead South Korea towards a “nuclear-free era”.

Speaking at an event to mark the closure of the country’s oldest nuclear plant, Kori-1, he said: “So far, South Korea’s energy policy pursued cheap prices and efficiency. “Cheap production prices were considered the priority while the public’s life and safety took a back seat. But it’s time for a change.

We will abolish our nuclear-centred energy policy and move towards a nuclear-free era. We will completely scrap construction plans for new nuclear reactors that are currently under way.”

Moon added that he would not extend the operation of ageing reactors, many of which will come to the end of their lifespans between 2020 and 2030.

Weaning South Korea off nuclear power, however, could take decades, and there is expected to be opposition from construction companies, which have increased technology exports under Moon’s nuclear-friendly predecessors.

The country was the fifth-largest producer of nuclear energy last year, according to the World Nuclear Association, with its 25 reactors generating about a third of its electricity.

The former president Lee Myung-bak saw nuclear as an important source of clean energy, while Park wanted to increase the number of reactors to 36 by 2029.

Moon recognised the role of nuclear power in South Korea’s rapid economic development, but added that Japan’s Fukushima disaster – which prompted the evacuation of tens of thousands of people – had convinced him that his country must look to new sources of energy.

The country’s economic status has changed, our awareness on the importance of the environment has changed. The notion that the safety and lives of people are more important than anything else has become a firm social consensus,” he said.

Anti-nuclear campaigners have long warned of the potentially disastrous consequences of a meltdown at a nuclear plant in South Korea, where many reactors are close to densely populated areas.

The public’s support for nuclear power has weakened since the 2011 Fukushima meltdown and a 2013 corruption scandal over fake safety certificates for reactor parts.

The Fukushima nuclear accident has clearly proved that nuclear reactors are neither safe, economical nor environmentally friendly,” Yonhap news agency quoted Moon as saying.

South Korea is not safe from the risk of earthquakes, and a nuclear accident caused by a quake can have such a devastating impact.”

He also plans to close at least 10 ageing coal-fired power plants before his term ends in 2022 and to boost renewables’ share of the energy mix to 20% by 2030.

Denuclearization Started by the Newly Elected South Korea’s Administration

South Korea’s administration has learned well from Japan’s Fukushima Daiichi nuclear disaster, whereas Japan’s administration is still living in denial orchestrating cover-up and lies.

 

southkoreacu.jpgSouth Korea currently operates 25 nuclear reactors, which generate about 30 percent of the country’s power supply

 

S. Korea to scrap all plans to build new nuclear reactors


South Korea’s new President Moon Jae-In vowed on Monday to scrap all plans to build new nuclear reactors as he seeks to steer Asia’s fourth-largest economy clear of atomic power.

Moon, who swept to power with a landslide election win last month, campaigned on promises to phase out atomic energy and embrace what he says are safer and more environmentally-friendly power sources including solar and wind power.

The Fukushima nuclear meltdown in Japan sparked by a powerful earthquake in March 2011 sparked widespread public concern in neighbouring South Korea over its own aged atomic plants.

“We will dump our atomic-centric power supply and open the door to the post-nuclear era,” Moon said in a speech marking the decommissioning of the country’s first nuclear reactor, the Kori-1.

“I will scrap all preparations to build new reactors currently underway and will not extend lifespan of current reactors,” he said.

Many reactors are located dangerously close to residential areas in the densely-populated nation, Moon said, warning of “unimaginable consequences” in case of a nuclear meltdown.

“South Korea is not safe from the risk of earthquake, and a nuclear accident caused by a quake can have such a devastating impact,” he said.

South Korea currently operates 25 nuclear reactors, which generate about 30 percent of the country’s power supply.

Many of them will see their lifespans expire between 2020 to 2030, with decisions on whether to extend some of their operations set to be made during Moon’s 2017-2022 term.

Moon, during his presidential campaign, vowed to try to eventually shut down all nuclear power plants across the country, although doing so will likely take decades.

Major corruption scandals involving state nuclear power agencies in recent years and a series of earthquakes last year further fanned public distrust and concerns over the safety of the plants.

Moon on Monday also vowed to decommission “as soon as possible” another aged atomic plant in the southeast, whose original 30-year lifespan had been extended by another decade to 2022.

He also vowed to introduce “post-coal” policy in line with his campaign promise to abandon coal power to ease air pollution in the country, which has the highest level of small air pollutant particles among OECD member nations.

But experts say shutdown of coal power plants could dramatically hike utility cost in the country where coal power generates about 40 percent of entire power needs.

Korea’s oldest nuclear reactor ceases operation

Kori No. 1, South Korea’s oldest nuclear reactor located in Busan, ceased operation Sunday at midnight after four decades.

Its operator Korea Hydro and Nuclear Power Co. said that it cut the power supply Saturday and began the cooling-down process of the reactor.

20170618000189_0.jpg
Kori No.1, South Korea’s first and the oldest nuclear reactor is seen in southern city of Busan.

 

It was officially decommissioned, with the temperature of the reactor gradually dropping to 90 degrees Celsius, from its normal operation at 300 degree Celsius, the KHNP said. Officials will then relocate the spent nuclear fuel stored inside the rector to a liquid sodium-cooled reactor for reprocessing.

The actual dismantling of the facilities is expected to start no later than 2022. The KHNP expects that at least 634 billion won ($559 million) is required for the dismantling. They also need to submit a dismantlement plan within five years for the NCCS’ approval.

The state-run Nuclear Safety and Security Commission, which approved earlier this month the permanent shutdown of Kori No. 1, said it will continue to check the safety management of the suspended reactor on a regular basis until the dismantlement.

Following the government’s approval in 2007, Kori No. 1’s operation was extended by 10 years after a 30-year run.

Some experts oppose the planned reprocessing of nuclear waste, saying the technology, though effective in reducing the volume of waste, could complicate waste disposal by creating different types of radioactive waste.

Under President Moon Jae-in, the South Korean government aims to close all nuclear power plants by shutting down aged facilities and eventually phasing out the rest over the next 40 years.

Korea’s first nuclear plant suspended after 40 years of operation

Built as Korea’s first nuclear power plant at Gijang County, Busan, Gori-1 came to a halt after completing its four decades of service, providing electricity since 1978. Gori-1 ended its chapter in the history of Korean nuclear power generation, being the first-ever nuclear powerhouse and the first of its kind to be out of service for good.

The Nuclear Safety and Security Commission (NSSC) opened its 70th meeting on Friday and announced that it has approved the permanent suspension of Gori-1, requested by the Korea Hydro and Nuclear Power (KHNP) last June. Under the recent approval, KHNP will stop operating the aged plant, and will cool nuclear fuels as of midnight on June 19. KHNP plans to dissemble the plant in earnest starting in 2022.

Gori-1 opened an era of commercial nuclear power generation in Korea on April 29, 1978. Meeting the rapidly increasing power demands amid economic growth, it has layed grounds for the nation to develop into an industrial state. While it reached its design life (30 years) in June 2007, the plant was resuscitated and was operated for an additional 10 years after undergoing full repair and consensus with residents.

Some view the first permanent suspension of a Korean nuclear plant as the first step towards denuclearization by the new administration. During his campaign, President Moon Jae-in pledged to immediately close down outdated nuclear plants and reduce nuclear power generation. Under the recent decision made by NSSC, experts view that the extension policy for the lifecycle of a nuclear plant will be set as “once for 10 years.” KHNP will hold a ceremony to celebrate the permanent halt of Gori-1 on June 19.

Plutonium found in urine of 5 workers exposed to radiation

94 Plutonium-300x300.jpg

TOKYO (Kyodo) — A small amount of plutonium was found in the urine of five workers exposed to radiation in an accident earlier this month at a nuclear research facility in Ibaraki Prefecture, a hospital operator said Monday.

The result shows that the five workers have suffered internal radiation exposure following the June 6 accident at the Japan Atomic Energy Agency’s Oarai Research & Development Center in the coastal town of Oarai.

They had been receiving medication to facilitate the discharge of radioactive materials from their bodies since the accident and will continue to do so, said the National Institutes for Quantum and Radiological Science and Technology, the operator of the hospital.

The five, although showing no signs of deterioration or notable change in their health, were hospitalized again from Sunday for the treatment.

In the accident, radioactive materials were released into the air in the room where the five were working when one opened a metal container holding plutonium and uranium powder samples and a plastic bag containing the samples inside suddenly ruptured.

Initially, the agency said up to 22,000 becquerels of plutonium-239 were found in the lungs of one of the five workers, while up to 5,600 to 14,000 becquerels of the radioactive substance were found in the lungs of three other workers. It said at the time that the four had suffered internal radiation exposure.

But the facility operator has since said a subsequent check by the National Institute of Radiological Sciences has found no plutonium in the lungs of any of the five workers. It has not ruled out the possibility that what was actually detected was radioactive substance left on the workers’ bodies after decontamination.

Also on Monday, JAEA President Toshio Kodama again apologized over the accident, saying at a press conference, “The agency as a whole had problems in the prediction of risks.”

He said he has no intention of resigning for now but will take “appropriate” responsibility depending on the cause of the accident.

The agency submitted a report compiling the causes of the accident and measures to be taken to prevent a recurrence to the Nuclear Regulation Authority, the state’s nuclear safety watchdog.

HIROSHIMA — The chairman of a joint Japan-U.S. research organization studying the long-term effects of radiation exposure on humans is expected to apologize to hibakusha — survivors of the 1945 U.S. atomic bombings of Hiroshima and Nagasaki — who were studied but generally not treated by the organization’s American predecessor, it has been learned.

Radiation Effects Research Foundation (RERF) Chairman Ohtsura Niwa will give his apology at a June 19 ceremony here commemorating the 70th anniversary of the organization’s establishment, to which hibakusha will be invited.

It is believed that this will mark the first time for a top RERF official to offer a direct, public apology to its subjects and those of its predecessor. “There’s an ironclad rule that one must develop relationships with human research subjects,” Niwa says. “But that sort of thinking didn’t exist in the 20th century. We must improve our relationships with hibakusha.”

Established in 1947 under the orders of U.S. President Harry Truman, the RERF’s predecessor, the Atomic Bomb Casualty Commission (ABCC), began to collect data on hibakusha in Hiroshima. The ABCC began similar studies on hibakusha in Nagasaki the following year. In both cities, subjects, as a rule, went untreated. Japanese authorities also took part in the research, following up on hibakusha years after they were exposed to the bombs. In 1975, the ABCC was reorganized into the bi-national RERF.

Hibakusha have said that the ABCC forcibly took them to research facilities where they were stripped to have their photos taken. Many have been angry with the ABCC for treating them like guinea pigs and violating their human rights, and the organization has long been criticized for gathering data from hibakusha but not treating them.

“Officially, the ABCC did not provide treatment, and instead ran tests on hibakusha and sent them home. It’s only natural that hibakusha harbor negative feelings toward the organization, and that they have had such feelings has been made clear from various records,” RERF Chairman Niwa told the Mainichi Shimbun. “I must apologize.”

There are no records of the organization’s past chairmen or other top officials directly apologizing to hibakusha, and the RERF says it is highly likely that Niwa’s apology will be the first.

In a speech at the outset of the upcoming ceremony, Niwa is expected to say something about the ample criticism and protest against the fact that researchers from the very country that dropped the atomic bombs had collected data from hibakusha, and that he is sorry that such an unfortunate period existed. Content similar to that of the planned speech was included in an RERF pamphlet published in 1995, but few people know about it.

As for hibakusha being stripped naked for tests and bereaved families being asked to donate the bodies of family members who died from radiation exposure, Niwa says, “The U.S. side was not knowledgeable about Japanese culture and traditions, so there was cultural friction. But such steps were necessary for the sake of science.”

Satoru Ubuki, a member of a committee for the preservation of historical records at the RERF, a former Hiroshima Jogakuin University professor, and an expert on the history of atomic bombing, said of the upcoming apology, “The RERF probably determined that to continue conducting research on second- and third-generation hibakusha, it will be more likely to gain their cooperation if the organization apologizes.”

Meanwhile, Nagoya University researcher Hiroko Takahashi, who is well-versed in the ABCC, says, “While there is significance to reflecting on and offering regret for the past, the remarks (Niwa makes) must not justify all research carried out by the RERF. The organization receives funding from the U.S. Department of Energy, and just as the ABCC had military objectives, that fundamental characteristic of the organization remained even after the RERF succeeded the ABCC. Among the data that was sent to the U.S. military in the early days of the RERF are many whose purpose remains unclear, so studies conducted at the time should be verified with the participation of a third party.

A-bomb survivors submit petition for nuclear ban

 

Representatives of Japanese atomic bomb survivors have compiled a petition of nearly 3 million signatures calling for a nuclear weapons ban treaty. The group handed the document to the chair of the ongoing UN meeting on the convention.

The second round of negotiations aimed at concluding the world’s first-ever nuclear weapons ban treaty started on Thursday at UN headquarters in New York.

On the second day of talks on Friday, representatives of atomic bomb survivors in Hiroshima and Nagasaki, Toshiyuki Mimaki and Masako Wada presented the petition to the chair of the meeting, Costa Rica’s envoy Elayne Whyte. They say their groups collected 2.96 million signatures over just more than a year since last April.

Wada handed the petition over along with a paper crane, a symbol of peace. She said the signatures represent the voices of atomic bomb survivors and citizens, and thanked the chair for her leadership.

Whyte responded that the main purpose of the treaty is to eliminate the suffering caused by nuclear weapons. The representatives applauded her when she said the signatures are very important for the negotiators.

After the handover, Wada observed that the draft treaty incorporates the Japanese word “hibakusha,” meaning atomic bombing survivor. She said she believes this shows the delegates have recognized the group’s long years of anti-nuclear activities.

Also in New York, atomic bomb survivor Masao Tomonaga from Nagasaki met Japan’s UN Ambassador Koro Bessho to relay a message from the Nagasaki mayor, Tomihisa Taue.

The message described a feeling of disappointment that is spreading among Nagasaki citizens over Japan’s absence from the negotiations.

Tomonaga said Bessho told him he understands their feeling, but Japan cannot decide on its own to leave the nuclear umbrella, and has had to make a difficult choice regarding the ongoing talks.
