Fukushima operator accused of cover-up over ‘contaminated’ water set to be poured into the Pacific

19 November 2019

The Japanese government has been accused of a cover-up after it refused to allow independent testing of water from the Fukushima power plant that is likely to be released into the Pacific Ocean.

Officials at the industry ministry on Monday said the water stored at the crippled nuclear site was “safe” to release into the Pacific Ocean, despite concerns about radioactive material from environmental and citizens’ groups.

Following a recent visit to the plant, the Tokyo Electric Power Co (Tepco) told The Telegraph that concerns over security prevented independent testing.

“Other organisations are not permitted to carry out tests of the water”, Hideki Yagi, a spokesman for Tepco, told The Telegraph.

“If we are going to allow external organisations to test the treated water then we would need to go through very strict procedures and due process because that water is contaminated. If it is taken outside this facility, then there need to be strict regulations”.

Both Greenpeace and the Citizens’ Nuclear Information Centre (Cnic), an anti-nuclear lobbying group, suggested that Tepco may be trying to cover up the true scale of contamination of water stores at the site.

Shaun Burnie, senior nuclear specialist for Greenpeace, says the refusal to permit third-party testing only serves to raise new concerns about plans to discharge the water into the ocean.

“Moving nuclear material always carries risk, but for the purpose of independent analysis it would be justified”, he said. “Tepco has lost trust across society in Japan as well as in the international community, including in South Korea, and providing samples for analysis would be in their best interests – unless they are covering something up.

“There are many questions about the effectiveness of Tepco’s … technology so providing samples that could verify their reports on content would go some way to demonstrating their commitment to transparency”, Mr Burnie added.

“It won’t remove doubts that they are covering up major issues at the site – but would be an improvement on the current situation”.

Hideyuki Ban, co-director of Cnic, said: “There would need to be lots of checks because there is a lot of water, but right now it looks very much to the outside world that they are trying to cover something up – as they have a long history of doing – and it would be very much in their best interests to be transparent on this.

“If they don’t, how will they ever get back any of the public trust that they have lost completely since the accident?” Mr Ban said.

During a recent visit to the plant, Tepco officials told The Telegraph that a decision on how to dispose of the water must be made soon as tanks at the site are already near capacity and there is limited space to construct new storage facilities. The company estimates that capacity will be reached in the summer of 2022.

The industry ministry on Monday told a government committee considering methods to dispose of the more than a million tons of water presently being stored in hundreds of tanks at the site that the risk to humans associated with releasing the water into the ocean would be “small”.

Discharging the water into the Pacific over the course of a year would amount to between just one-1,600th and one-40,000th of the radiation to which humans are naturally exposed, the ministry officials told the committee.

Estimates indicate that annual radiation levels near the release point after a release would be between 0.052 and 0.62 microsieverts at sea, the officials said, and 1.3 microsieverts in the atmosphere. That compares with around 2,100 microsieverts that humans come into contact with each year in everyday life.

The ministry how emphasised that no final decision has been reached on how or when the water will be disposed of.

The water became contaminated with radiation when it was used to cool three of the six reactors at the plant that suffered melt-downs after being damaged in the March 2011 earthquake and tsunami. Ground water is also seeping into the basement levels of the reactor buildings, with an additional 120 tons of water accumulating every day.

Tepco was forced to admit earlier this year that efforts to remove varying amounts of 62 radionuclides – including strontium, iodine, caesium and cobalt – from the water through the ALPS equipment had not been completely successful.

Officials of the company have added that testing of the water is presently carried out by Tokyo Power Technology Ltd, which it claims has advanced analytical skills and “very high” reliability. Tokyo Power Technology is a subsidiary of Tepco that was set up two years after the Fukushima disaster.

Monitoring is also conducted by the government-funded Japan Atomic Energy Agency and the Japan Chemical Analysis Centre.

Azby Brown, lead researcher for Tokyo-based monitoring organisation Safecast Japan, a group that monitors radiation, said the lack of transparency means the risks to marine life of releasing the water are relatively unknown.

“We don’t have enough data to evaluate the impact that any release with those concentrations will have on marine life,” he said.

“The expected doses that they are talking about are quite low and therefore the amount of radiation that is absorbed into marine life and then into humans when they eat fish would also be quite low.

“But that has to be full of caveats because the way that information has been presented is confusing and not transparent so ordinary people do not understand and cannot make informed decisions.”

Fukushima accused of cover-up over ‘contaminated’ water set to be poured into the Pacific

November 19, 2019

The Eastern authorities has been accused of a quilt up after it refused to enable honest checking out of water from the Fukushima vitality plant that is doubtless to be launched into the Pacific Ocean.

Officers at the industry ministry on Monday said the water saved at the crippled nuclear plan used to be “capable” to release into the Pacific ocean, despite concerns about radioactive cloth from environmental and citizens’ groups.

Following a most modern consult with to the plant, the Tokyo Electrical Energy Co (Tepco) instructed The Telegraph that concerns over security prevented honest checking out.

“Assorted organisations are now not permitted to internet exams of the water”, Hideki Yagi, a spokesman for Tepco, instructed The Telegraph.

“If we’ll enable exterior organisations to take a look at the treated water then we would deserve to struggle thru very strict procedures and due route of because that water is rotten. If it is taken originate air this facility, then there wish to be strict rules”.

The corporate estimates water storage ability will seemingly be reached within the summer season of 2022

Both Greenpeace and the Electorate’ Nuclear Files Centre (Cnic), an anti-nuclear lobbying community, instructed that Tepco might perhaps well perhaps be attempting to quilt up trusty scale of contamination of water stores at the positioning.

Shaun Burnie, senior nuclear specialist for Greenpeace, says the refusal to permit third-internet collectively checking out only serves to fetch unique concerns about plans to discharge the water into the ocean.

“Transferring nuclear cloth repeatedly carries possibility, but for the unbiased of honest diagnosis it might perhaps perhaps truly perhaps be justified”, he said. “TEPCO has misplaced belief across society in Japan moreover within the worldwide community, including in South Korea, and providing samples for diagnosis might perhaps well perhaps be in their most efficient interests – unless they are maintaining something up.

“There are a form of questions regarding the effectiveness of Tepco’s … technology so providing samples that can additionally voice their reports on affirm material would scamper some technique to demonstrating their dedication to transparency”, Mr Burnie added.

“It will additionally now not settle away doubts that they’re maintaining up foremost points at the positioning – but might perhaps well perhaps be an development on the sizzling worry”.

Hideyuki Ban, co-director of Cnic, said: “There would deserve to be tons of assessments because there is a form of water, but decent now it looks to be very powerful to the originate air world that they’re attempting to quilt something up – as they bear a lengthy history of doing – and it might perhaps perhaps truly perhaps be very powerful in their most efficient interests to be clear on this.

“In the occasion that they don’t, how will they ever internet attend any of the general public belief that they bear misplaced fully since the accident?” Mr Ban said.

During a contemporary consult with to the plant, Tepco officers instructed The Telegraph that a resolution on easy suggestions to internet rid of the water desires to be made rapidly as tanks at the positioning are already advance ability and there’s dinky suppose to create unique storage facilities. The corporate estimates that ability will seemingly be reached within the summer season of 2022.

The industry ministry on Monday instructed a authorities committee brooding about suggestions to internet rid of the higher than 1 million a form of water presently being saved in tons of of tanks at the positioning that the possibility to humans connected to releasing the water into the ocean might perhaps well perhaps be “small”.

Discharging the water into the Pacific over the route of a yr would quantity to between decent one-1,600th and one-40,000th of the radiation to which humans are naturally exposed, the ministry officers instructed the committee.

Estimates conceal that annual radiation phases advance the release level after a release might perhaps well perhaps be between 0.052 and nil.62 microsievert at sea, the officers said, and 1.3 microsieverts within the ambiance. That compares with spherical 2,100 microsieverts that humans reach into contact with each and each yr in everyday lifestyles.

The ministry how emphasised that no final resolution has been reached on how or when the water will seemingly be disposed of.

The water turned rotten with radiation when it used to be used to frosty three of the six reactors at the plant that suffered soften-downs after being broken within the March 2011 earthquake and tsunami. Ground water is additionally seeping into the basement phases of the reactor buildings, with an further 120 a form of water collecting each and on daily basis.

Tepco used to be compelled to admit earlier this yr that efforts to settle away varying quantities of 62 radionuclides – including strontium, iodine, caesium and cobalt – from the water thru the ALPS instruments had now not been fully a hit.

Officers of the corporate bear added that checking out of the water is presently implemented by Tokyo Energy Technology Ltd, which it claims has evolved analytical expertise and “very high” reliability.

Azby Brown, lead researcher for Tokyo-essentially based totally mostly monitoring organisation Safecast Japan, a community that shows radiation, said the dearth of transparency technique the dangers to marine lifetime of releasing the water are quite unknown.

“We blueprint now not bear ample recordsdata to deem the affect that any release with these concentrations might perhaps well perhaps bear on marine lifestyles”, he said..

“The anticipated doses that they’re talking about are fairly low and attributable to this truth the quantity of radiation that is absorbed into marine lifestyles after which into humans after they eat fish would additionally be fairly low

“Nevertheless that must be paunchy of caveats for the reason that technique that recordsdata has been provided is confusing and now not clear so traditional of us carry out now not understand and might perhaps well perhaps now not assemble instructed decisions.”

TEPCO estimates tritium volume for disposal from Fukushima plant

Tritium, radioactive hydrogen, is clinically recognized as causing cancer, birth defects and genetic mutation. That should be plastered on the side of nuclear power plants.
safe_image.php.jpg
Storage tanks containing processed but still contaminated water at the crippled Fukushima No. 1 nuclear power plant
November 18, 2019
Tokyo Electric Power Holdings Co. on Nov. 18 released for the first time an estimate of the annual disposal amount of radioactive tritium from its crippled Fukushima No. 1 nuclear power plant.
The volume will vary from 27 trillion to 106 trillion becquerel, depending on the commencement date and ending time of the disposal process, according to a report the utility presented to a subcommittee of the Ministry of Economy, Trade and Industry.
In comparison, a domestic nuclear power plant in operation usually dumps liquid radioactive waste that contains tritium, a radioactive form of hydrogen, from several hundred billion up to 100 trillion becquerel annually into the ocean, according to the ministry.
In line with the comparison, there will be no health-related problem by being exposed to radiation of the tritium disposed of from the Fukushima plant, the ministry said.
TEPCO made its preliminary calculation in substantiating the impact of the long-term storage of contaminated water.
The estimate set the total amount of tritium contained in the radioactive water stored in the tanks to be 860 trillion becquerel as of January 2020. Four starting dates of the disposal process were set as the beginning of 2020, 2025, 2030 and 2035.
The estimate assumed two ending times for the disposal at the end of 2041 and 2051, based on the progress schedule set by the government and the utility, which predicted the reactor decommissioning to be completed in 30 to 40 years.
The amount of tritium is expected to decay naturally over time. Still, the estimate revealed that the later the starting date is, the more the annual disposal amount will be.
Since the 2011 Great East Japan Earthquake and tsunami crippled the plant in Fukushima Prefecture, TEPCO has processed and stored a large amount of radiation-contaminated water in tanks on the grounds of the plant.
Even after being treated with a filtering system, the polluted water still contains tritium, which will be released when the water is dumped into the ocean or is disposed of in another manner.
The volume of contaminated water has continued to accumulate from the cooling of melted nuclear fuel debris and underground water pouring in.
TEPCO said that it cannot keep installing more storage tanks for the contaminated water due to space limitations of the site and that all the tanks will be full by around the summer of 2022.
If the disposal process hasn’t begun by then, TEPCO will have to build more storage tanks, exceeding the limit, which will lead to a delay in the construction of other facilities that are necessary for the decommissioning work of the Fukushima No. 1 plant.

Japan’s METI says it’s ‘safe’ to dump radioactive water from Fukushima nuclear disaster into ocean

safe_image.php.jpg
Tanks storing radioactive water at the Fukushima No. 1 nuclear power plant in Okuma, Fukushima Prefecture, in February
Nov 18, 2019
Japan’s industry ministry said Monday it would be safe to release water contaminated by the Fukushima nuclear disaster into the ocean, stressing that the amount of radiation measured would be very small compared to what humans are naturally exposed to annually.
Discharging the water into the Pacific Ocean over the course of a year would amount to between just one-1,600th and one-40,000th of the radiation that humans are naturally exposed to, the Economy, Trade and Industry Ministry told a government subcommittee on the issue.
Water used to cool the melted-down cores and groundwater near the disabled plant contains some radioactive materials, and is currently being collected and stored in tanks on the plant grounds.
But space is running out fast, and the government is exploring ways to deal with the water — already more than 100 tons and increasing every day.
According to the ministry, annual radiation levels near the release point is estimated at between 0.052 and 0.62 microsievert at sea and 1.3 microsieverts in the atmosphere, compared with the 2,100 microsieverts that humans are naturally exposed to annually.
While government officials stress the safety of releasing the water, opposition lawmakers as well as neighboring South Korea have expressed concern. Local fishermen are also opposed to the release of the water into the sea, fearing the potential impact on fish stocks.
The water is being treated using an advanced liquid processing system, or ALPS, though the system does not remove the relatively nontoxic tritium and has been found to leave small amounts of other radioactive materials.
The tanks storing the water are expected to become full by the summer of 2022, according to Tokyo Electric Power Company Holdings Inc., the operator of the Fukushima No. 1 nuclear power plant.
The plant was disabled by a magnitude 9.0 earthquake and ensuing tsunami on March 11, 2011.
A nuclear expert from the International Atomic Energy Agency said in 2018 that a controlled discharge of such contaminated water “is something which is applied in many nuclear facilities, so it is not something that is new.”

Japan accused of trying to justify nuclear dump

Fukushia 2019
Nov 07, 2019
COVER?Tokyo Electric Power Co has said new storage tanks could be built to hold radioactive water at its stricken plant, a Greenpeace Germany member said
The Japanese government’s claim that it will run out of room to store radiation-contaminated water at the Fukushima Dai-ichi nuclear power plant in two years is not true, and is simply an attempt to justify discharging polluted water into the Pacific Ocean, a Greenpeace International member said yesterday.
Shaun Burnie, senior nuclear specialist at Greenpeace Germany who has conducted long-term surveys in Japan, was invited by Greenpeace Taiwan to talk about the issue at a news conference in Taipei.
An earthquake and a tsunami in March 2011 caused the plant’s reactor fuel rods to melt and large amounts of radioactive-contaminated water was released into the Pacific.
As of Oct. 22, more than 1 million cubic meters of processed polluted water was stored at the treated water storage tank, while the current storage capacity is nearly 1.1 million cubic meters, Burnie said.
Tokyo Electric Power Co in August said the tank would reach full capacity by the summer of 2022 and that there is no room for expansion at the site, he said.
However, the company in a meeting in September said that land is available to build additional tanks, Burnie added.
The claim of insufficient capacity is just an excuse to cover the Japanese government’s political agenda, Burnie said, adding that Tokyo has the option of storing contaminated water for a longer period.
If Japan approves the discharge, radioactive tritium and other radionuclides in the water will likely enter the East China Sea, and eventually the waters surrounding Taiwan through the subtropical gyre, he said.
However, even if the Japanese government decides to discharge polluted water into the ocean, it would not be able to carry out the plan immediately, as it might take years to build outflow pipelines, he said.
In addition to protests from local fishers, especially those living along Japan’s Tohoku coast, the Japanese government would face strong pressure from the international community for discharging polluted water, he said, adding that it is a long-term problem that should be approached more cautiously.
The Fukushima Dai-ichi disaster has led to catastrophic results, and the Taiwanese government should be lauded for making the “brave and correct” decision to phase out nuclear power plants, Burnie said.
Taiwan should call on the Japanese government, via diplomatic or non-governmental channels, to shoulder its responsibility as a Pacific nation and not discharge radiation-contaminated water into the sea, National Nuclear Phase-out Action Platform spokesperson Tsuei Su-hsin (崔愫欣) said.
As Taiwan generates less than 10 percent of its electricity from nuclear power — much lower than the ratio in Japan before the 2011 disaster, it should persist in its goal of phasing out all nuclear power plants by 2025, Tsuei said.

Citizens’ Committee on Nuclear Energy proposes long-term storage for treated water from damaged Fukushima Daichi plant

191005.JPG

5th October 2019

On October 3, the Citizens’ Committee on Nuclear Energy, whose members include academics, technical experts, and NGOs, made a new proposal to deal with contaminated water from the damaged Fukushima Daiichi Nuclear Plant after the water has been treated. The proposal, submitted to Ministry of Economy, Trade and Industry (METI), the Ministry of the Environment (MOE), and the Nuclear Regulation Authority, is to convert the treated water to solid form by mixing with mortar, and storing it on land. Citizens’Comittee on Nuclear Energy (CCNE)

01Figure 1 (Prepared by Yasuro Kawai, Citizens’ Committee on Nuclear Energy, for October 3, 2019 press conference)

 

However, Tokyo Electric Power Company (TEPCO) rejected the concept of large-tank storage, claiming that it takes three years to install each tank, that the efficiency of site utilization is not significantly different from that of tanks currently being used, that a floating roof design may result in rainwater mixing with the contents, and that there would be major volume of leakage in the event of damage to the tanks.

Those claims were rebuffed in a presentation by Yasuro Kawai of the Citizens’ Committee on Nuclear Energy (regulations subcommittee) at a press conference on October 3. He said that the installation of large tanks takes 1.5 to 2 years, that they actually improve the efficiency of site utilization, that a dome-shaped design could be used to prevent mixing with rainwater, that large tanks are robust and have a proven track record in oil storage, and that perimeter walls would be needed as a measure to prevent leakage.

Advantages and disadvantages of mortar solidification proposal

The proposal by the Citizens’ Committee on Nuclear Energy is to mix contaminated water with cement and sand to solidify it, then pour the mixture into concrete tanks and store it partially underground. Mr. Kawai described achievements using this approach at the Savannah River nuclear reservation in South Carolina, the United States.

Discussion about land-based storage has finally begun

The Citizens’ Committee on Nuclear Energy has long taken the position that treated water from the so-called Advanced Liquid Processing System (ALPS) should not be released into the ocean. It has been proposing land-based storage using large tanks, an approach that has a proven track record for the storage of oil reserves.

In August 2018, at a hearing held by METI’s ALPS subcommittee, fisheries-related stakeholders and many other participants expressed the view that long-term land-based storage should be used for the treated water. In response, Chairman Kazuyoshi Yamamoto promised to consider the land based storage plan as an option, and the topic finally came up at the 13th sub-committee meeting, held on August 9, 2019.

02Figure 2 (Prepared by Yasuro Kawai, Citizens’ Committee on Nuclear Energy, for October 3, 2019 press conference)

 

The advantages are that no radioactive substances need to be released into the environment, and the approach works with existing technologies. Disadvantages include low volumetric efficiency and evaporation of moisture due to heat generation.

Local community consent would also be required, because the site would become a permanent disposal site.

Is there really a lack of space for onsite storage?
Media have repeatedly reported claims that onsite storage space will run out by the summer of 2022, but is that really true? According to documents from on September 27, TEPCO explained to the ALPS Subcommittee that the site has about 81,000 square meters reserved for temporary storage facilities for spent fuel and fuel debris.

03Figure 3 (Document 3, 14th subcommittee meeting on handling of ALPS treated water)

TEPCO also claims that in the first half of the 2020s, the site is required for facilities for analysis, mock-up facilities for fuel debris retrieval, equipment and material storage, and research facilities, etc.

04Figure 4 (Document 3, 14th subcommittee meeting on handling of ALPS treated water)


But is it realistic and necessary to attempt to remove fuel debris?

The location and condition of the fuel debris is not precisely known due to high radioactivity. An unreasonable effort to remove it will expose workers to a large amount of radioactivity.

The Citizens’ Committee on Nuclear Energy has proposed a “debris non-removal” option of keeping the debris isolated for 100 years, after which it would be dealt with, as one option that should be seriously considered, in order to avoid technical risks, enormous costs, and radiation exposure of workers.

Is it necessary to construct research facilities on the site?

Furthermore, at METI’s ALPS subcommittee, committee members have asked many questions, for example, about giving consideration to using sites where soil is currently being dumped, and expansion of the current site. In all cases, METI responded that such options were “difficult.” However, there was no evidence of any serious consideration having been made of whether or not the ideas raise were really possible.

05

METI should immediately consider the land based storage proposal from the Citizens’ Committee on Nuclear Energy by setting up an ALPS subcommittee or a new committee.

Korea brings up Fukushima’s radioactive water disposal issue at WHO

6600_6606_3839.jpg
October 15, 2019
The Ministry of Health and Welfare said that it conveyed the Korean government’s concerns over radioactive water disposal at the Fukushima Daiichi nuclear plant in Japan, during the 70th World Health Organization’s West Pacific Regional Conference.
Kang Dae-tae, assistant minister for the Planning and Coordination Office at the ministry and chief representative of the regional meeting, expressed concern about the handling of radioactive water from the Fukushima nuclear power plant and urged the Japanese government and international agencies to respond with care.
“Disposing of radioactive water into the sea is not just a problem for Japan but an international issue that can have a significant impact on the marine environment of the Western Pacific region and the health of its people,” Kang said. “The WHO Western Pacific Regional Office, along with relevant international organizations such as the International Atomic Energy Agency (IAEA), has to minimize the impact on the health of the residents of the region.”
Kang urged the international bodies to disclose relevant information transparently so that there is no unnecessary anxiety when Japan decides on how to dispose of the contaminated water.
In response to Korea’s concerns, the Japanese health ministry officials said that they have made efforts to share information and clean up contaminated water, but have not currently decided on how to deal with Fukushima’s contaminated water.
The Japanese officials also noted that the decision to discharge the radioactive waters would be made under international standards such as the International Radiation Protection Committee.
The Fukushima Daiichi nuclear plant is now sitting on a million-ton of water contaminated with radioactive elements while the amount grows around 150 tons a day.
While the Japanese government has claimed that it has removed most of the radioactive isotopes using an elaborate filtration process, it could not eliminate one isotope, tritium, so it has been storing the water in large tanks, which will fill up by 2022.
Some scientists have claimed that tritium causes harm to humans except in very high concentrations, and the IAEA also argues that properly filtered Fukushima water could be diluted with seawater and then safely released into the ocean without causing environmental problems.
However, other experts have claimed that even the diluted version of tritium can affect cell structures in plants, animals, or humans. The consensus of dumping the water into the Pacific Ocean also faces fierce backlash from both the Japanese fisherman groups and the Korean government, they said.

South Korea Brings Fukushima Radioactive Water Sea Dumping Issue at International London Convention and Protocol of Marine Pollution

S. Korea raises issue of Fukushima’s contaminated water dump to international convention

Japan says it will keep international community updated on progress

157077756772_20191012Song Myeong-dal, the Ministry of Oceans and Fisheries ocean environment policy officer, represents South Korea during a consultative meeting of contracted parties to the London Convention and London Protocol on Oct. 7.

Oct.11,2019

The South Korean Ministry of Oceans and Fisheries (MOF) raised the danger of Japan’s ocean dump of contaminated water from the Fukushima Nuclear Power Plant as an international issue at a meeting in London concerning an international convention. Japan responded by saying it would keep the international community informed of the progress on an ongoing basis. The developments suggest South Korea was successful in raising international interest in and concern about Japan’s irresponsible approach to the disposal of contaminated water from Fukushima.

On Oct. 10, the MOF reported that the day before, representatives had attended a consultative meeting of contracted parties to the London Convention and Protocol on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter – which opened in London on Oct. 7 – to express concerns to Japan concerning the handling of the contaminated water from Fukushima and request ongoing interest in the issue at the consultative meeting level. The meeting was attended by representatives of 47 contracted parties, as well as international organizations such as the OECD and NGOs including Greenpeace.

The Japanese government has recently talked several times about the ‘unavoidability’ of an ocean dump as a way of dealing with contaminated water from the Fukushima Nuclear Power Plant,” Song Myeong-dal, MOF ocean environment policy officer and senior South Korean representative at the meeting, said on Oct. 9.

If [Japan] does release contaminated water from the plant into the ocean, this could have an impact on the global oceanic environment and be in violation of the aims of the London Protocol,” Song warned. Article 2 of the London Convention and Protocol states that contracting parties “shall individually and collectively protect and preserve the marine environment from all sources of pollution and take effective measures [. . . ] to prevent, reduce and where practicable eliminate pollution caused by dumping or incineration at sea of wastes or other matter.”

Song stressed that the Japanese government “needs to be transparent about its means of handling contaminated nuclear power plant water, adequately communicating and discussing important matters such as its handling methods and schedule with neighboring countries and the international community in the future and deciding on a safe and rational approach.”

In order to find a method of contaminated nuclear power plant water handling that the international community can be confident is safe, I think this matter should be discussed on an ongoing basis by the consultative meeting of contracted parties to the London Convention and Protocol ,” he suggested.

In response, a representative of the Japanese government reiterated the position that the matter was “not something to be discussed by the consultative meeting,” adding that there had been “no decision within the Japanese government on how to handle the contaminated nuclear power plant water” and that the international community would be “kept informed about the process.” The representative also presented information on the water’s handling that was previously shared in September with locally stationed diplomats in Japan.

Greenpeace expresses similar concern about ocean dump

The issue of contaminated water had not previously been discussed within the context of the London Protocol at past consultative meetings since the Fukushima Nuclear Power Plant disaster. In addition to South Korea, representatives from China and Chile also expressed concerns at the latest meeting over the possibility of Japan dumping the contaminated water into the sea and suggested that the issue would be the focus of ongoing discussions at the meeting.

The NGO Greenpeace similarly shared concerns about the possibility of an ocean dump in a document at the meeting containing “concerns and questions about the Fukushima Nuclear Power Plant contaminated water release plan.” Contending that the Japanese system for handling contaminated nuclear power plant water is “inefficient,” it proposed that the international community work together on finding a solution.

During a Compliance Group meeting held ahead of the consultative meeting on Oct. 3–4, the South Korean representative strongly emphasized the need to review the ocean release of radioactive waste matter within the context of the London Protocol, insisting that Japan should not be allowed to make a unilateral decision on whether to proceed with the dumping of contaminated nuclear power plant water into the ocean. The Compliance Group meeting was established to discuss whether contracted parties to the protocol are complying with their obligations.

In bilateral meetings with major countries and through issues raised in the Compliance Group setting, the South Korean government rallied support for the position that this matter should be addressed at the consultative meeting,” said Song Myeong-dal.

We will continue to make such requests at this meeting and other international meetings going forward so that the Japanese government can find an approach that we can be confident is safe,” he pledged.

South Korea Brings Fukushima Wastewater Issue to London Convention Meeting

October 11, 2019

The South Korean Ministry of Oceans and Fisheries (MOF) raised the danger of Japan’s contaminated water from the Fukushima Nuclear Power Plant as an international issue at a meeting to the London Convention. 

 

South Korea’s Ministry of Oceans and Fisheries (MOF) deemed the danger of Japan’s contaminated water from the Fukushima Nuclear Power Plant as an international issue at a meeting to the London Convention. 

The London Convention controls pollution of the seas and oceans by dumping and covers the deliberate disposal of wastes and other matter into the world’s waters, according to the U.S. EPA. The discharged water will have a direct influence on the marine life and ecosystem in its territorial waters and eventually the people in Korea, according to the Korea Times.

As of Aug. 22, approximately 1.1 million tons of contaminated water is being stored in 977 tanks at the decommissioned power plant in Fukushima, which was destroyed by the 2011 earthquake and ensuing tsunami

The Japanese government said recently it will only build more facilities through 2020, which will bring the total stored volume to 1.37 million tons, according to Science Page News. The storage facilities are projected to be filled by August 2020, which suggests that there will be no more tanks to hold the 170 tons of radiation-contaminated water created daily.

If [Japan] does release contaminated water from the plant into the ocean, this could have an impact on the global oceanic environment and be in violation of the aims of the London Protocol,” said Song Myeong-dal, MOF ocean environment policy officer and senior South Korean representative. “In order to find a method of contaminated nuclear power plant water handling that the international community can be confident is safe, I think this matter should be discussed on an ongoing basis by the consultative meeting of contracted parties to the London Convention and Protocol.”

In response, a representative of the Japanese government said that the matter was not something to be discussed by the consultative meeting and that the international community would be kept informed about the process, reported the Hankyoreh.

“There is another option to deal with radioactive water. Japan can keep it in the tanks until the radiation level becomes low enough. But this takes time and money. It will take about 300 years until it is okay to discharge the water,” said Kim Ik-jung, a former medical professor and member of the Nuclear Safety and Security Commission to the Korea Times.

South Korea plans to continue to raise the wastewater issue to the international community until Japan comes up with a safe and acceptable solution, according to the Hankyoreh.

S. Korea raises worries over Fukushima waste water at global maritime conference

hghjkl.jpg
October 10, 2019
South Korea raised the issue of Japan’s reported plan to release radioactive wastewater from the Fukushima nuclear plant into the Pacific Ocean …at a global conference of the International Maritime Organization in London this week.
During a meeting to discuss the London Convention and Protocol… Seoul’s fishery ministry demanded that Tokyo transparently disclose information over its handling of the contaminated water and called for continuous discussion of the issue.
The London Protocol is aimed at preventing marine pollution and bans the export of waste or other matter to other countries for dumping or incineration at sea.
However, the direct dumping of wastewater from land to sea has been absent from the discussion.
 
With the management of radioactive waste on the agenda for this year’s meeting, …representatives from China and Chile also expressed their concern and called for more discussions over the matter.
Ghana’s representative to the IMO, who is the chair of the meeting, also noted that the issue can be brought up for discussion and that Japan should provide information.
For the first time, Japan’s representative said it will continue to provide transparent information concerning the contaminated water at Fukushima.
 
This is the latest effort by the Korean government to deter Tokyo from discharging an estimated one.one million tons of contaminated water stored at its Fukushima plant.
Last month, Seoul raised the issue at the General Conference of the International Atomic Energy Agency.
At the gathering, Japan dismissed criticisms, claiming they were not based on scientific evidence.

At Fukushima plant, a million-tonne headache: Radioactive water

nz_daiichi_051055.jpgA Tokyo Electric Power Company researcher shows processed water where tritium remains, at a lab in Fukushima Dai-ichi nuclear plant in Okuma, Fukushima prefecture, Japan, on Oct 2, 2019.

Oct 5, 2019,

FUKUSHIMA (AFP) – In the grounds of the ravaged Fukushima Daiichi nuclear plant sits a million-tonne headache for the plant’s operators and Japan’s government: tank after tank of water contaminated with radioactive elements.

What to do with the enormous amount of water, which grows by around 150 tonnes a day, is a thorny question, with controversy surrounding a longstanding proposal to discharge it into the sea, after extensive decontamination.

The water comes from several different sources: some is used for cooling at the plant, which suffered a meltdown after it was hit by a tsunami triggered by a massive earthquake in March 2011.

Groundwater that seeps into the plant daily, along with rainwater, add to the problem.

A thousand, towering tanks have now replaced many of the cherry trees that once dotted the plant’s ground.

Each can hold 1,200 tonnes, and most of them are already full.

“We will build more on the site until the end of 2020, and we think all the tanks will be full by around the summer of 2022,” said Mr Junichi Matsumoto, an official with the unit of plant operator Tepco in charge of dismantling the site.

Tepco has been struggling with the problem for years, taking various measures to limit the amount of groundwater entering the site.

There is also an extensive pumping and filtration system, that each day brings up tonnes of newly contaminated water and filters out as many of the radioactive elements as possib

HIGHLY RADIOACTIVE

The hangar where the decontamination system runs is designated “Zone Y” – a danger zone requiring special protections.

All those entering must wear elaborate protection: a full body suit, three layers of socks, three layers of gloves, a double cap topped by a helmet, a vest with a pocket carrying a dosimeter, a full-face respirator mask and special shoes.

Most of the outfit has to be burnt after use.

“The machinery filters contain radionuclides, so you have to be very protected here, just like with the buildings where the reactors are,” explained Tepco risk communicator Katsutoshi Oyama.

Tepco has been filtering newly contaminated water for years, but much of it needs to go through the process again because early versions of the filtration process did not fully remove some dangerous radioactive elements, including strontium 90.

The current process is more effective, removing or reducing around 60 radionuclides to levels accepted by the International Atomic Energy Agency (IAEA) for water being discharged.

But there is one that remains, which cannot be removed with the current technology: tritium.

Tritium is naturally present in the environment, and has also been discharged in its artificial form into the environment by the nuclear industry around the world.

There is little evidence that it causes harm to humans except in very high concentrations and the IAEA argues that properly filtered Fukushima water could be diluted with seawater and then safely released into the ocean without causing environmental problems.

‘ABSOLUTELY AGAINST IT’

But those assurances are of little comfort to many in the region, particularly Fukushima’s fishing industry which, like local farmers, has suffered from the outside perception that food from the region is unsafe.

Mr Kyoichi Kamiyama, director of the radioactivity research department at the regional government’s Fisheries and Marine Science Research Centre, points out that local fishermen are still struggling eight years after the disaster.

“Discharging into the ocean? I’m absolutely against it,” he told AFP.

At the national government level, the view is more sanguine.

“We want to study how to minimise the damage (from a potential discharge) to the region’s reputation and Fukushima products,” an Industry Ministry official said.

The government is sensitive to fears that people inside Japan and farther afield will view any discharge as sending radioactive waste into the sea.

No decisions are likely in the near term, with the country sensitive to the international spotlight that will fall on Japan as it hosts the Olympic Games next year.

Environmentalists are also resolutely opposed to any discharge into the sea, and Greenpeace argues that Tepco cannot trusted to properly decontaminate the water.

The solution, said Greenpeace senior nuclear specialist Shaun Burnie, “ultimately can only be long-term storage and processing”.

Japanese Report Confirms Hazardous Radioactive Materials Contained in Contaminated Fukushima Water

PYH2018100811030001300
South Korean environmental activists hold a rally in front of the Japanese Embassy in Seoul on Oct. 8, 2018, to protest against Japan’s decision to release the Fukushima nuclear plant’s radioactive, contaminated water into the sea.
October 4, 2019
SEOUL, Oct. 4 (Korea Bizwire) — As Japan seeks to release contaminated water from its disabled Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean, South Korean media revealed that the tainted water contains hazardous radioactive materials.
KBS News reported on Thursday that a report submitted by the Tokyo Electric Power Co. (TEPCO) to the Japanese Ministry of Economy, Trade and Industry early this week confirmed the presence of the hazardous radioactive materials, such as cesium and strontium, in the contaminated water.
The report said that cesium, strontium, and iodine 129 exceeded standard levels in 82 percent of all contaminated water kept in Fukushima as of October of last year.
It was also revealed that 17 percent of the tainted water emitted radiation that was ten times stronger than the annual limit on radiation exposure (1 mSv/Y), while 7 percent of the water contained radioactive materials that were 100 times stronger.
In an interview with KBS News, a TEPCO official said that “problems with the filters and several systems in the water treatment facility prevented it from being run at full capacity for a certain period.”
TEPCO said it can no longer accommodate the contaminated water that is being produced every day since the East Japan Earthquake in 2011 and has proposed a plan to release it to the atmosphere or the sea.
Roughly 170 tons of contaminated water is being produced at the Fukushima Power Plant every day. As of last July, the total amount of tainted water had reached 1.15 million tons.
The Japanese government, in contrast, has been claiming that the water now only contains tritium, a radioactive hydrogen isotope known to exist in the natural environment.
Neighboring states, including South Korea, are strongly opposing the idea of releasing the water, since it may cause secondary damage.
“The International Atomic Energy Agency understands the issues and concerns that we face. They are also keeping a close watch on the matter,” said Uhm Jae-sik, head of the Nuclear Safety and Security Commission.

Seoul-Tokyo feud deepens over radioactive water

optimize.jpg
Rep. Choi Jae-sung of the ruling Democratic Party of Korea (DPK), third from left, speaks during a meeting for the party’s special committee to counter Japan’s “retaliatory” trade restrictions on South Korea in this July 11 file photo, at the party’s meeting room at the National Assembly in Seoul.
October 3, 2019
The Japanese government’s continued reluctance to openly support dumping radioactive wastewater for fear of creating a fresh controversy over the destroyed Daiichi Nuclear Power Plant in Fukushima is adding concern to the already deteriorated Seoul-Tokyo relations.
 
Currently, more than 1 million tons of contaminated water is held in almost 1,000 tanks at the plant, according to government data. However, the site administrators have warned that they will run out of space by the summer of 2022.
 
A proposed plan to release the contaminated water into the Pacific Ocean is angering South Korea. The government, which has yet to officially lift an import ban on fishery and agricultural products from Fukushima introduced in 2013, has recently claimed that discharging the water will pose a “grave threat” to the marine environment. But Japan has rejected this charge.
 
The Japanese Embassy in Seoul has been posting atmospheric radiation levels monitored in Seoul and Fukushima Prefecture since Sept. 24, updating them on a daily basis. The embassy said the levels in Fukushima were similar to other major cities worldwide including Seoul.
 
In response, a committee launched by the ruling Democratic Party of Korea (DPK) published a map centered on the devastated nuclear plant that shows radiation-contaminated areas. The map marks stadiums for the 2020 Olympics ― including Miyagi, Fukushima Azuma, Ibaraki Kashima, Tokyo, and the Saitama Super Arena ― as contaminated by radiation from the 2011 Fukushima disaster.
 
The DPK said the map was based on public data released by the Minnano Data Site, a Japanese civic organization, that lists radioactive measurements of food and soil.
 
“We made the map to show measures we can take to protect our people’s lives and safety,” said Rep. Choi Jae-sung, chairman of the committee. “Japan’s plan to release contaminated water is controversial, as marine products from many regions in Japan could be contaminated, and this could influence decisions by visitors for the Tokyo Olympics as well as participating athletes.”
 
Japanese Defense Minister Taro Kono tweeted that he ordered the posting of radiation levels on the website of the embassy in Seoul in response to growing concerns over the issue here.
 
But critics are urging Japan to “do something more” as they say releasing the contaminated water will further raise concerns among South Korean and Japanese people.
 
They say Tokyo’s plan to use an advanced liquid-processing system to remove highly radioactive substances such as cesium from the water doesn’t completely filter out tritium, a radioactive isotope of hydrogen commonly found in cooling water released into the ocean by coastal nuclear power plants.
Nuclear specialists said tritium has the potential to in concentrated doses to damage cell structures in plants, animals and people, claiming “dilution” wasn’t the best option to avoid this. They said Tokyo should continue to store the water in areas outside the plant site despite opposition from local residents who were evacuated.
 
Meanwhile, the foreign ministry summoned Tomofumi Nishinaga, a minister for economic affairs at the Japanese Embassy in Seoul, to complain about the plan to release the contaminated water into the Pacific Ocean.

South Korea inspects ships traveling from Fukushima for radiation

South-Korea-inspects-ships-traveling-from-Fukushima-for-radiation.jpg
A South Korean politician said Wednesday seawater near Fukushima Prefecture (pictured) was being brought in and being discharged into Korean waters.
Oct. 2 (UPI) — South Korea is stepping up surveys of ships originating from areas near Fukushima, Japan.
Seoul’s ministry of maritime affairs and fisheries said Wednesday it will work with South Korea’s nuclear safety committee to assess radiation levels in ballast water originating from ships traveling from Fukushima, Yonhap reported.
Japan said in September the country has “no choice” but to discharge radioactive water into the ocean, a statement that drew concern from neighbors like South Korea.
South Korea is surveying 32 coastal areas and another 32 offshore zones near the peninsula on a quarterly basis to assess radiation, according to the report.
The South Korean decision comes after local lawmaker Kim Jong-hoe, a member of the National Assembly’s Agriculture, Forestry, Livestock and Fisheries Committee, said that it was “confirmed” seawater near Fukushima Prefecture was being brought in and being discharged into Korean waters.
South Korea upholds a ban on Japanese seafood originating from the Fukushima nuclear disaster zone.
According to Kim on Wednesday, ships originating from areas near Fukushima, including Aomori, Iwate, Miyagi, Ibaraki and Chiba prefectures discharged about 128 million tons of ballast water from September 2017 to July of this year. The water was discharged at South Korean ports, Kim said.
The 2011 nuclear crisis that occurred following the Tohoku earthquake was a tragedy that forced farmers in the area to leave behind livestock.
The Asahi Shimbun reported this week the area is also home to feral ostriches following the quake.
The ostriches are descendants of birds kept at a ostrich park that opened in the area in 2001, according to the report.
Fukushima remains off-limits to people due to high radiation.

Japanese citizens nationwide opposed to Pacific Ocean discharge of Fukushima radioactive water support storage and processing – new opinion poll

4d3ef5c1-gp0stsx96_low_res_with_credit_line.jpg

 

October 1, 2019, Tokyo… Nearly four times as many Japanese citizens oppose the discharge of highly contaminated water from the Fukushima Daiichi nuclear plant into the Pacific Ocean than support it, according to a Greenpeace commissioned poll

.(1) The polling of 3000 citizens in Fukushima and Niigata prefecture, as well as wider Japan, showed most expressed their support for storage of over 1 million tons of water rather than release to the Pacific Ocean. Only a small percentage approve of Government plans for discharge. Greenpeace commissioned Rakuten Insight, a pioneer in Japanese online market research to conduct the poll which was conducted between 19-24 September 2019.

 

The results show some slight variation in opinion between those in Fukushima and those in Niigata and wider Japan. Averaging of the poll revealed that 48.6% oppose marine discharge and 12.9% approve. In Fukushima, 15.9% approve of discharge, while 43.3% oppose. Of those who oppose discharge, nationwide 51% stated that their principal concerns were that discharging will have a negative impact, not just in Fukushima and wider Japan, but also internationally. In Fukushima, 52.9% think it will have a negative effect on Fukushima fisheries.

 

We deliberately set out to try and understand the level of understanding Japanese citizens have, what they were thinking and why. They show only a small percentage approve of discharging to the Pacific ocean, and by a wider margin, most oppose. The strongest opposition comes from Niigata citizens and wider Japan. One clear message they send to the Abe government is that the opposition to discharge is not limited to Fukushima fisheries (2) and Fukushima prefecture but is nationwide. Most of those polled who are opposed to discharge show both a concern for the international impacts in the Asia/Pacific region any discharge would have and also the impact it would have on Fukushima fisheries,” said Shaun Burnie, senior nuclear specialist with Greenpeace Germany (Tokyo).

 

A Greenpeace report (3) in January 2019 showed that METI in 2016 deliberately excluded the option to store and process the contaminated water to remove radioactive tritium, despite receiving technical submissions from U.S. nuclear companies, and the U.S. Department of Energy. The myth promoted by the Government and TEPCO ever since is that tritium removal is not possible. The Greenpeace report also provided analysis on the failure of the ALPS processing systems, which means that over 800,000 tons of contaminated water contains dangerous radionuclides such as Strontium-90, tens to thousands of times above regulatory limits. TEPCO has committed to processing this water – but doubts remain as to how effective this will be.

 

As the Fukushima nuclear disaster has shown, ocean currents will disperse any future radioactive materials released not only into the Pacific,  but also the East China Sea, Sea of Japan/East Sea.(4) In recent weeks, the Japanese government plans for discharge have been challenged by the South Korean government at the International Atomic Energy Agency (IAEA), while Greenpeace addressed the issue to diplomats attending the United Nations Human Rights Council in Geneva given Japan’s obligation to prevent citizens from exposure to harmful radioactivity. The issue will also be debated at the International Maritime Organization meeting of parties to the London Convention and London Protocol which opens on 7th October in London.

 

The people of Japan are sending a message to the government that they will not accept deliberate radioactive pollution of the marine environment. As the polling shows, the Japanese people are concerned about the international impact of any discharge. This was never just a domestic issue. The international focus on TEPCO’s water crisis is only going to escalate in the coming months – and the Abe government has the means to end this by making the only justifiable decision – commit to no discharge and instead decide on long term storage and processing,” said Burnie.

 

Greenpeace commissioned the poll to include the views of 1000 Niigata citizens as they are under direct threat, including from marine contamination, from any restart of TEPCO’s Kashiwazaki Kariwa nuclear plant. TEPCO is seeking the restart of reactors 6&7, despite the existence of major seismic fault lines both adjacent and through the site. The nuclear plant is TEPCO’s last hope of remaining a nuclear plant operator.

Taiwan warns Japan over radioactive water release

fuku-900x540
The Fukushima Daiichi nuclear power plant in 2016. Over the years since, tens of thousands of people have worked to decontaminate the plant and stop leaks. But what to do about the leftover waste water?
September 25, 2019
Some in Taiwan also fear a repeat of Japan’s disaster as a nuclear plant sits close to fault lines on the island
Taiwan has warned Japan not to dump radioactive water from the burned-out reactor cores at the Daiichi Nuclear Power Plant in Fukushima into the nearby ocean, fearing prevailing currents may eventually push the polluted water to its own shores.
In March 2011, a devastating tsunami triggered by an undersea tremor buffeted the major nuclear base supplying power to Tokyo, and the apocalyptic disaster made a large swathe of the neighboring areas uninhabitable as well as a spillover of polluted dust into the capital city.
Taiwan’s Atomic Energy Council (AEC) fears that currents could carry polluted water across the Pacific Ocean to the coastline as far as North America, which may flow back to Taiwan in three to six years.
The AEC said on Tuesday it would file a complaint with the Japanese government if it decided to discharge the radioactive water into the sea, but it also stressed that Japanese officials and scientists had not yet reached a consensus on what to do with the staggering amount of contaminated water.
Japan’s environmental protection ministry and Tokyo Electric Power Co which owns the mangled nuclear reactors in Fukushima say the one-million-tonne storage of radioactive water used to cool the reactors to prevent further meltdown would be filled to the brim within three years.
Japan is mulling a plan to release part of the less radioactive waste water – reportedly 10,000 tonnes – into the sea, an idea that instantly stoked fears in neighboring countries, including Taiwan and South Korea.
If the water from the reactors enters the Pacific Ocean, it would first be carried by currents to North America from Alaska, Canada’s British Columbia all the way down to California, before moving southward and reaching Taiwan in three to six years, according to the US National Oceanic and Atmospheric Administration and the Germany-based Helmholtz Centre for Ocean Research.
That said, it is believed that by the time the radioactive water returned to Asia and reached Taiwan, the pollutants would have been attenuated to a concentration of nearly one in 10,000, far less harmful after the dilution process in the vast Pacific Ocean.
The island’s nuclear energy watchdog says that water and fishery products in nine ports across Taiwan are regularly sampled to test for radioactivity, without having any abnormal findings so far.

‘It will take 300 years before contaminated water is safe to discharge into sea’

Not only 300 years, more than 300 years….

Experts warn there is no safe threshold for radioactive exposure
September 18, 2019
By Kim Jae-heun
Nuclear experts from around the world are condemning the Japanese government’s possible move to discharge radioactive water from the destroyed Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean.
The plan is raising concerns especially in Korea, Japan’s closest neighbor, as the discharged water will have a direct influence on the marine life and ecosystem in its territorial waters and eventually the people themselves.
As of Aug. 22, about 1.1 million tons of contaminated water are being stored in 977 tanks at the power plant in Fukushima, which was destroyed by an earthquake and resultant tsunami in 2011. The Japanese government has said it will only build more facilities through 2020 and this will bring the total stored to 1.37 million tons.
By August 2020, all the storage facilities are projected to be filled and there will be no more tanks to hold the 170 tons of radiation contaminated water created every day.
Tokyo has remained quit on how it will cope with the radioactive water, not giving any clear answers to the international community. The possibility of discharging it into the sea was raised recently after Shaun Burnie, a senior nuclear specialist at the German branch of the environmental group Greenpeace, warned in August that Japan could dump over 1 million tons of radioactive waste into the Pacific.
Since then, Japanese government officials began to discuss the issue. They say almost all the radioactivity has been removed from the water except for tritium, claiming this metal is relatively nonhazardous ― something experts disagree with, noting it can cause cancer and fetal deformities.
Former Japanese Environment Minister Yoshiaki Harada said in a recent interview that there was no other option but to dilute the contaminated water by pumping it into in the sea in order to dispose of it; although Japanese Chief Cabinet Secretary Yoshihide Suga said Harada’s remarks were only his personal opinion and the government had not made any decision.
Burnie, however, says this was only the “cheapest” option.
“This is the principal reason. They do not want to pay the full costs of storing and processing the contaminated water, including removal of radioactive tritium,” Burnie said during an email interview with The Korea Times. “For these reasons, in 2016, the Ministry of Economy Task Force on water turned down the options offered by various companies to develop tritium removal technology.”
Kim Ik-jung, a former medical professor at Dongguk University who served as a member of the Nuclear Safety and Security Commission here, agreed that discharging the contaminated water into the sea was the cheapest and fastest way to get rid of it, but at the same time it was also the most dangerous.
“There is another option to deal with radioactive water. Japan can keep it in the tanks until the radiation level becomes low enough. But this takes time and money. It will take about 300 years until it is okay to discharge the water,” Kim said.
Hiroaki Koide, an assistant professor at the Research Reactor Institute of Kyoto University in Japan, said he thinks the Japanese government will go ahead and discharge the radiation-contaminated water into the sea in the near future, and this must be stopped at all cost.
“Being exposed to radiation, even if it is a very small amount, is still dangerous. Nobody should discharge radiation into the environment including the ocean,” Koide said.
According to a Greenpeace report released earlier this year, the Japanese government has reviewed five options to deal with the accumulating radioactive waste, and discharging it into the Pacific Ocean was considered the most reasonable as it would only cost 37.7 billion won, based on 2016 calculations by the Ministry of Economy, Trade and Industry. The ministry also concluded that other options also entailed various risks.
Greenpeace Korea believes that if the Japanese government decides to discard the contaminated water, it will only do so after the 2020 Tokyo Olympics.
It argues that the Shinzo Abe administration will not court controversy while it has the world’s full attention during the Games scheduled between July 24 and Aug. 9.
“The Japanese government cannot just discard radioactive waste at its own discretion. It is watching how other countries are reacting to its hints that it could discharge the contaminated water into the ocean. That’s why the former Japanese environment minister made such remarks on the day he retired,” a Greenpeace Korea official said.
Concerns over Tokyo Olympics amid radiation issue
The Japanese government’s plan to dump contaminated wastewater is not the only issue related to Fukushima.
In less than a year, Japan will hold one of the world’s biggest sporting events, and nuclear experts around the world have expressed concerns that participating athletes could be exposed to radiation.
Koide says Olympic committees from all over the world should decide to boycott the Tokyo Olympic Games.
Last year, the scholar sent a document to Olympic committee members worldwide, warning of the radiation danger athletes and visitors will face.
In the letter, Koide questioned Japan’s suitability as the host of a worldwide event like the Olympics, and the country’s capability to take strict safety measures necessary to protect athletes and other visitors.
The professor further explained that the resultant radioactive materials leak from the explosion at the Fukushima plant in 2011 is still affecting “an area whose vastness has not been precisely determined yet.”
“Seven years have passed and the situation has not improved at all. As an honorable and honest citizen of Japan, I am asking you to reconsider your country’s participation in the Olympic Games that will take place in Tokyo in 2020,” he wrote in a letter sent in October 2018.
Burnie sided with Koide by saying that the Japanese government was being dishonest in the way it was using the Olympics to communicate with the world and its citizen that there has been a full recovery from the Fukushima nuclear disaster, and there are no radiation risks.
“The reality of Fukushima Prefecture is highly complex with many citizens living in areas with low radiation risks ― at the same time there are areas in Fukushima, such as Namie and Iitate, where radiation risks are high, and tens of thousands of citizens remain displaced as evacuees,” Burnie said.
The Japanese government also announced that it would host baseball games and softball games in Fukushima, while providing food made from ingredients grown in the region.
Japanese Prime Minister Abe ate a rice ball made with crops grown there to demonstrate that the food was safe, but many criticized that this was a dangerous act.
“I don’t know if Abe ate it because he really thought it was safe or just for show. But it was a really dangerous act. Whatever is affected by radiation is dangerous without question,” Kim said.
“According to textbooks, if a person is exposed to radiation, be it internal or external, he or she is highly likely to develop cancer or hereditary disorders. Heart disease is also a common result.”
Korean government’s response
The Korean government is alarmed by the possible discharge of contaminated water, but is unable to strongly request the Japanese government not to do so, because the latter keeps saying it has yet to make a decision about how it will dispose of the water.
In mid-August, the Ministry of Foreign Affairs asked the Japanese government to state its official stance on the issue. Environment Minister Cho Myung-rae said on social media Sunday, “We’ve asked the Japanese government to share material about how it is coping with the contaminated water from Fukushima, but it has avoided giving answers. It should take responsibility as a member of the international community by sharing information with its neighboring countries and holding sufficient talks with them.”
The government also called on international society at a general meeting of the International Atomic Energy Agency (IAEA) in Vienna, Austria, Monday, to take collective action against the possibility of Japan discharging the water into the ocean.
Mun Mi-ock, the first vice minister of science and ICT, said in a keynote speech that Japan has failed to find an answer to the disposal of the radioactive waste since the meltdown at the Fukushima plant in March 2011.
“It is an important international issue that can affect the marine environment of the whole world, so the IAEA and its members need to take joint action,” Moon said.
The IAEA has no right to regulate a particular country, but the government believes public opinion formed against Japan could prevent it from dumping the radioactive water into the ocean as it counts 171 countries as members.
