Long haul to clean up radioactive debris in Fukushima’s shattered nuclear reactors – remote probe in use
IAEA urges Japan to slow the Fukushima wastes clean-up – delay release to Pacific till after Olympic Games
IAEA urges Japan to take ample time in Fukushima cleanup https://phys.org/news/2019-01-iaea-urges-japan-ample-fukushima.html January 31, 2019 by Mari Yamaguchi The International Atomic Energy Agency urged Japan on Thursday to spend ample time in developing a decommissioning plan for the tsunami-damaged Fukushima nuclear power plant and to be honest with the public about remaining uncertainties.
The cores of the three reactors melted after a massive 2011 earthquake and tsunami. Utility and government officials plan to start removing the melted fuel in 2021, but still know little about its condition and have not finalized waste management plans.
“The IAEA review team advises that before the commencement of the fuel debris retrieval activities, there should be a clear implementation plan defined to safely manage the retrieved material,” the report said. “TEPCO should ensure that appropriate containers and storage capacity are available before starting the fuel debris retrieval.”
The report also urged the government and TEPCO to carefully consider ways to express “the inherent uncertainties involved” in the project and develop “a credible plan” for the long term. It advised TEPCO to consider adopting contingency plans to “accommodate any schedule delays.”
Dale Klein, a former U.S. Nuclear Regulatory Commission chairman who heads a TEPCO reform committee, said in a recent interview that the decommissioning should not be rushed, even if the government and TEPCO have set a schedule and people want to see it move faster.
“It’s much better to do it right than do it fast,” he said, adding that it’s also good not to rush from a health and safety perspective. “Clearly, the longer you wait, the less the radiation is.”
He said he would be “astounded” if the current schedule ends up unchanged.
In order to make room in the plant compound to safely store the melted fuel and for other needed facilities, about 1 million tons of radioactive waste water currently stored in hundreds of tanks will have to be removed. The IAEA team, headed by Xerri Christoph, an expert on radioactive waste, urged the government and TEPCO to urgently decide how to dispose of it.
Nuclear experts, including officials at the IAEA and Japanese Nuclear Regulation Authority, have said a controlled release of the water into the Pacific Ocean is the only realistic option. A release, however, is unlikely until after the Tokyo 2020 Olympic Games in order to avoid concerns among visitors from overseas.
A new type of robot to probe inside damaged Fukushima nuclear reactor
Toshiba unveils robot to probe melted Fukushima nuclear fuel, WP, By Mari Yamaguchi | AP, January 28 YOKOHAMA, Japan — Toshiba Corp. unveiled a remote-controlled robot with tongs on Monday that it hopes will be able to probe the inside of one of the three damaged reactors at Japan’s tsunami-hit Fukushima nuclear plant and grip chunks of highly radioactive melted fuel.
The device is designed to slide down an extendable 11-meter (36-foot) long pipe and touch melted fuel inside the Unit 2 reactor’s primary containment vessel. The reactor was built by Toshiba and GE.
An earlier probe carrying a camera captured images of pieces of melted fuel in the reactor last year, and robotic probes in the two other reactors have detected traces of damaged fuel, but the exact location, contents and other details remain largely unknown.
Toshiba’s energy systems unit said experiments with the new probe planned in February are key to determining the proper equipment and technologies needed to remove the fuel debris, the most challenging part of the decommissioning process expected to take decades.
…….. The probe will mainly examine the fuel debris’ physical condition rather than its radioactive components or other details which require actual sampling and safe storage……. https://www.washingtonpost.com/world/asia_pacific/toshiba-unveils-robot-to-probe-melted-fukushima-nuclear-fuel/2019/01/28/4214f596-2314-11e9-b5b4-1d18dfb7b084_story.html?utm_term=.3bfe336cb31c
A bit of good news – Radioactive Cesium-137 diminishing in 2 Fukushima rivers, after close to 8 years
 Survey finds concentration of radioactive cesium-137 rapidly decreasing in 2 Fukushima rivers,
http://www.the-japan-news.com/news/article/0005504609 January 26, 2019
The Yomiuri ShimbunThe concentration of radioactive cesium-137, which was spread about following the accident at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear power plant, has been rapidly decreasing in river waters in municipalities near the facility in Fukushima Prefecture, according to a survey by the Japan Atomic Energy Agency. Compared to the speed at which the radiation of cesium-137 naturally decreases, the concentration in the rivers is decreasing at a speed tantamount to 10 times that, said the JAEA, a national agency for research and development. The JAEA assesses that cesium on top of the ground is carried into rivers by rain but as the radioactive substance seeps underground, among other possible factors, the volume flowing into rivers might have decreased. Following the March 2011 nuclear accident, radioactive materials were dispersed and fell onto the earth. Among these materials was cesium-137, which has a relatively long half-life of about 30 years and is releasing radiation even now. From April 2015 to March 2018, the agency examined two rivers in the prefecture — the Ukedogawa river in Namie and the Otagawa river in Minamisoma. It sampled the waters in a 20-kilometer area around the nuclear power plant and precisely measured the concentration of cesium-137 in them. Results showed the concentration in the Ukedogawa river was around 0.2 becquerels per liter at the start of the study, but had dropped to around 0.1 becquerels in March 2018, indicating the concentration was decreasing 10 times faster than normal. The Otagawa river also showed a similar trend, according to the agency. Takahiro Nakanishi, a senior researcher at the JAEA, said, “If the concentration in river waters relied on for agricultural purpose decreases, the result could help local people resume their agricultural activities.” |

Greenpeace study slams Japan’s plan to dump radioactive Fukushima water into the ocean
An estimated 1.09 million tonnes of water are presently stored in more than 900 tanks at the plant, which was destroyed by an earthquake and tsunami in March 2011, with up to 4,000 tonnes added every week.
The decision by the government and the plant’s operator, the Tokyo Electric Power Company (Tepco), to avoid developing the relevant technology “was motivated by short-term cost-cutting, not protection of the Pacific Ocean environment and of the health and livelihoods of communities along the Fukushima coast”, said Kazue Suzuki, campaigner on energy issues for Greenpeace Japan.
“We have raised the water crisis with the UN International Maritime Organisation and firmly stand with local communities, especially fisheries, who are strongly opposed to any plans to discharge contaminated water into their fishing grounds.”
The backlash against the plan jointly put forward by the government and Tepco began late last year after the Ministry of Economy, Trade and Industry (METI) held public hearings in Tokyo and Fukushima designed to convince local people that releasing the water into the ocean would have no impact on marine or human life.
Anti-nuclear and environmental groups had obtained data leaked from government sources, however, that showed that the water was still contaminated, triggering public anger. Tepco was forced to admit late last year that its efforts to reduce radioactive material – known as radionuclides – in the water had failed.
The company had previously claimed that advanced processes had reduced cancer-causing contaminants such as strontium-90, iodine-129 and ruthenium-106 in the water to non-detectible levels.
Despite the much-vaunted Advanced Liquid Processing System (ALPS) plant at Fukushima, Tepco has confirmed that levels of strontium-90, for example, are more than 100 times above legally permitted levels in 65,000 tonnes of water that have already been through the ALPS system.
In one of the hearings, Tatsuhiko Sato, a resident of Naraha who only returned to his home last spring because of contamination from the nuclear accident, accused Tepco of “not gathering all the data” and failing to adequately investigate reports that dangerous levels of radionuclides were still in the water after it was treated.
Local fishermen used the public hearing to express their “strong opposition” to plans to release the water, with one, Tetsu Nozaki, pointing out that while levels of radiation in locally caught fish and shellfish have been at or below normal levels for the past three years, releasing contaminated water would “deal a fatal blow” to the local fishing industry.
There has also been anger in some nearby countries, with environmental groups demonstrating in Seoul in November and Korea Radioactive Watch declaring that releasing the water “will threaten the waters of South Korea and other neighbouring nations”.
………..The Greenpeace report concludes that the water crisis at the plant will remain unresolved for the foreseeable future – and that the only viable option to safeguard local communities and the environment is to continue to store the water.
“The Japanese government and Tepco set an objective of ‘solving’ the radioactive water crisis by 2020 – that was never credible,” said Shaun Burnie, a nuclear specialist with Greenpeace Germany.
“The reality is that there is no end to the water crisis at Fukushima, a crisis compounded by poor decision-making by both Tepco and the government. Discharging into the Pacific is the worst option and must be ruled out.”https://www.scmp.com/news/asia/east-asia/article/2183175/greenpeace-slams-japans-plan-dump-radioactive-fukushima-water
High radiation levels in Fukushima area, but the Japanese government is pushing people back there
Fukushima Residents Return Despite Radiation, Eight years after the nuclear meltdown, wary citizens are moving back to contaminated homesteads—some not by choice, Scientific American, By Jane Braxton Little January 16, 2019
When the Fukushima Daiichi Nuclear Power Plant began spewing radioactive particles after it was clobbered by a tsunami in March 2011Kaori Sakuma fled. She bundled her infant and toddler into a car and left her husband and family in Koriyama, 44 miles west of the ruptured facility. “The truth is, I ran away,” she says. Confronting gas shortages and snarled roads, she transported her children 560 miles away to Hokkaido, about as far as she could get.
Radiation from the fuming plant spread over tile-roofed towns and rice paddies across an area the size of Connecticut. The meltdown 150 miles north of Tokyo drove more than 200,000 people out of the region. Most believed they were fleeing for their lives. Now, almost eight years after the accident, the government has lifted most evacuation orders. Nearly 122,000 people have been allowed to return to communities where weeds have overtaken parking lots. Most are elderly, relieved to be resuming their lives. Prime Minister Shinzo Abe is determined to end all evacuations by 2020, when Japan will host the Olympic Summer Games. The events will include baseball and softball competitions in Fukushima City, a mere 55 miles from the ruined reactors.
Around 35,000 other citizens still wait to return, but they and many others throughout northeastern Japan worry all of this is too soon. Radiation, which is generally linked to cancer, in some places continues to measure at least 5 millisieverts (mSv) a year beyond natural background radiation, five times the added level Japan had recommended for the general public prior to the incident. In certain spots radioactivity is as high as 20 mSv, the maximum exposure recommended by international safety experts for nuclear power workers.
In its haste to address the emergency, two months after the accident the Japanese government raised the allowable exposure from 1 mSv annually, an international benchmark, to 20 mSv. Evacuees now fear Abe’s determination to put the Daiichi accident behind the nation is jeopardizing public health, especially among children, who are more susceptible. Lifting most evacuations has also ended subsidies for evacuees, forcing many to return despite lingering questions.
As more people inside and outside the country absorb the radiation data, Japanese officials are confronting a collapse of public confidence. Before the accident residents in Japan (and the U.S.) were living with background radiation that averaged 3.1 mSv a year,most of it emanating naturally from the ground and space. In Japan and the U.S. many residents experience an additional 3.1 mSv annually, due mostly to medical testing. But the anxiety of Fukushima residents facing even higher levels is palpable. If the government is going to fully restore lives and livelihoods, it needs to regain their trust, says nuclear engineer Tatsujiro Suzuki, a professor at Nagasaki University and former vice chairman of the Japan Atomic Energy Commission. That, he says, should include respecting international safety standards for radiation and lowering the allowable level at least to 5 mSv, although he acknowledges “even 5 mSv is too high for children.”
……….Concern about children is one of the most controversial issues. When officials raised the allowable level of radiation to 20 mSv, including in schools, it was under the guise of giving people a measure of normalcy. But the May 2011decision became a flash point for opponents of the government’s handling of the accident. They were furious children would be subjected to the maximum radiation allowed for nuclear workers, spending day after day in buildings that increased their cancer risk to one in 200 people.
Sakuma was one of those who returned to Koriyama, from her outpost in Hokkaido. She did not want her young children to touch contaminated soil or water along their walk to school, so she carried them both on her small back. “We all want our kids to play in the dirt and pick flowers but I was afraid. We all were,” says Sakuma, now 46. ……https://www.scientificamerican.com/article/fukushima-residents-return-despite-radiation/
Russia’s Rosatom to manage accident plan at the Fukushima NPP
Russia’s Rosatom wins two bids for accident management at Fukushima NPP http://tass.com/world/1039631, January 12, 2019, MOSCOW, Russia’s state nuclear corporation Rosatom has been engaged in the nuclear control plan at Japan’s stricken Fukushima nuclear power plant and has already won two bids in that project, Rosatom CEO Alexei Likhachev said in a televised interview with Rossiya’24 news channel on Saturday.
“We have been engaged by Japan to implement the nuclear accident management plan at the Fukushima NPP. We have won two tenders and are getting ahead,” he said.
In September 2017, Rosatom’s First Deputy CEO Kirill Komarov said that Rosatom offered help to Japanese counterparts in handling the crippled Fukushima NPP.
The nuclear disaster at the Fukushima-1 power plant in March 2011 was triggered by an earthquake-induced tsunami that knocked out vital reactor cooling systems. This resulted in three nuclear meltdowns, hydrogen explosions and a massive release of radioactive waste, which contaminated the surrounding area. Clean-up operations continue at the power plant and adjacent territories. According to the current action plan, full decommissioning of the station may take place only around 2040.
Thyroid cancer impact on children and teens following Fukushima nuclear accident
More than 3,600 people died from causes such as illness and suicide linked to the aftermath of the tragedy. OVER 180 TEENAGERS and children have been found to have thyroid cancer or suspected cancer following the Fukushima nuclear accident, new research has found.
A magnitude 9.0 quake – which struck under the Pacific Ocean on 11 March 2011 – and the resulting tsunami caused widespread damage in Japan and took the lives of thousands of people……..
Cancer concerns
The accident at the nuclear power station in 2011 has also raised grave concerns about radioactive material released into the environment, including concerns over radiation-induced thyroid cancer.
Ultrasound screenings for thyroid cancer were subsequently conducted at the Fukushima Health Management Survey.
The observational study group included about 324,000 people aged 18 or younger at the time of the accident. It reports 
on two rounds of ultrasound screening during the first five years after the accident.
Thyroid cancer or suspected cancer was identified in 187 individuals within five years – 116 people in the first round among nearly 300,000 people screened and 71 in the second round among 271,000 screened.
The overwhelming common diagnosis in surgical cases was papillary thyroid cancer – 149 of 152 cases.
Worker death
In May, Japan announced for the first time that a worker at the stricken Fukushima nuclear plant has died after being exposed to radiation, Japanese media reported.
The man aged in his 50s developed lung cancer after he was involved in emergency work at the plant between March and December 2011, following the devastating tsunami.
The Japanese government has paid out compensation in four previous cases where workers developed cancer following the disaster, according to Jiji news agency.
However, this was the first time the government has acknowledged a death related to radiation exposure at the plant, the Mainichi daily reported.
The paper added the man had worked mainly at the Fukushima No. 1 nuclear plant and other atomic power stations nationwide between 1980 and 2015.
Following the disaster, he was in charge of measuring radiation at the plant, and he is said to have worn a full-face mask and protective suit.
He developed lung cancer in February 2016. https://www.thejournal.ie/thyroid-cancer-fukushima-nuclear-4364292-Dec2018/
International Atomic Energy Agency (IAEA) says Japan must urgently tackle Fukushima’s radioactive water buildup
Reuters 13th Oct 2018 , Japan must urgently tackle a buildup of contaminated water at its Fukushima
nuclear plant, destroyed by an earthquake and tsunami more than seven years
ago, the International Atomic Energy Agency (IAEA) said on Tuesday. The
call after a site visit by IAEA experts follows last month’s admission by
plant owner Tokyo Electric Power (Tepco), that water treated there still
contained radioactive material, despite having said for years it had been
removed.

Tepco to temporarily stop injecting water at Fukushima reactor
TEPCO to stop injecting water at Fukushima reactor https://www3.nhk.or.jp/nhkworld/en/news/20181109_10/ The operator of the Fukushima Daiichi nuclear power plant plans to temporarily stop injecting water into one of its damaged reactors to test the cooling of fuel debris.
Tokyo Electric Power Company announced it will conduct the 7-hour test at the No.2 reactor as early as March next year.
The unit is one of 3 in the 6-reactor facility that suffered a meltdown after the March 2011 earthquake and tsunami. The damaged reactors contain a mixture of molten nuclear fuel and structural parts.
TEPCO officials say water injections keep temperatures stable in the 3 reactors at around 30 degrees Celsius.
The planned experiment is aimed at checking how the debris is being cooled. It will be the first time to halt water injections into the reactor since they were stabilized after the accident.
TEPCO’s assessment says the reactor temperature would rise by around 5 degrees per hour if injections were halted by accident. But it says the rise will be limited to about 0.2 degrees per hour when natural heat radiation is taken into account.
TEPCO officials say they will begin cutting back on water injections by around half to 1.5 tons per hour for about a week as early as in January, before halting them completely in March after checking the results.
TEPCO estimates the 7-hour stoppage may raise the reactor temperature by about 1.4 degrees but says water injections will resume if the temperature rises more than 15 degrees.
Company officials say they want to assess changes in the temperature so they can use the data in future emergency cases, including earthquakes and tsunamis.
Fukushima nuclear disaster – whiteboard reveals the chaos in March 2011
“Stop monitoring, evacuate now,” an order said.
The next line follows, “1F3 (No. 3 reactor of Fukushima No. 1 plant) hydrogen explosion.”
“Don’t return here, head west,” another directive said.
Media representatives were invited on Nov. 8 for the first time to the emergency headquarters that was set up at the prefecture-run Environmental Radioactivity Monitoring Center of Fukushima here to monitor the radiation levels around the Fukushima No. 1 nuclear plant when a massive tsunami crippled the power supply on March 11, 2011.
The center was originally constructed as a facility to monitor radiation levels in the area as well as serve as an education center for nuclear power generation.
The headquarters were abandoned on the night of March 14, 2011, after the evacuation order was issued following the explosion at the No. 3 reactor building. No one since then has returned to use or tidy up the site………http://www.asahi.com/ajw/articles/AJ201811090033.html
PEACE BOAT AND GREENPEACE STILL CAMPAIGNING FOR FUKUSHIMA

https://metropolisjapan.com/peace-boat-and-greenpeace-still-campaigning-for-fukushima/
Metropolis interviews NGO leaders at the forefront of the recovery effort, BY SARAJEAN ROSSITTO OCTOBER 18, 2018 This past summer, while beaches in Fukushima were re-opening, UN experts were assessing how the nuclear disaster impacted people’s physical and mental health. The ending of government housing provision and living stipends for people from Fukushima in April 2017 greatly reduced the official numbers of disaster evacuees. Whatsmore, by making people from Fukushima invisible it gave the impression that problems were solved. I spoke with several NGO leaders about their work and the issues people from Fukushima face today. Meri Joyce, International Coordinator at Peace Boat, has been working on international programs and campaigns such as nuclear disarmament and Kazue Suzuki is an Energy Campaigner at Greenpeace Japan. The impossible choice of returning to areas too contaminated to safely live or face economic hardship only exacerbates the victimization of the displaced in Fukushima. The lack of support systems, Suzuki said, resulted in people falling into poverty. Joyce further explained that it is hard for people to put down roots even if more areas are designated as “safe” because hard and soft infrastructure were lacking. Even if school buildings are safe, who will work in those schools? If businesses get up and running, are there any customers? Greenpeace has served as witness to environmental risks in more than 55 nations for 47 years using non-violent direct action, advocacy and public education. Within days of 3/11, Amsterdam-based Greenpeace International dispatched experts to assist Greenpeace Japan with ocean radiation monitoring from a ship off the coast of Fukushima while other staff assessed terrestrial effects. Concerned that government radiation estimates were too conservative, they shared their radiation readings with governments, media and general public. To keep Fukushima visible, they release annual reports on radiation levels, the nuclear power industry and the socio-economic and health impacts the disaster on communities that depend on the nuclear power industry. Their 2017 report spotlighted rights’ violations — particularly those of women and children. A 2018 study shows that Fukushima radiation risks are expected to last into 2050 in some exclusion zone towns. Since its founding, about 35 years ago, Peace Boat has been trying to stimulate public discussion on energy, nuclear weapons and development at the local, national and international levels. Joyce shared examples of how issues have impacted their ship programs. Since 2008 they have invited Hiroshima and Nagasaki hibakusha (people who experienced atomic/nuclear bombings) to join Peace Boat cruises where they share their experiences at ports of call. Students on board learn from these elders while also engaging in dialogue about what should be done to build a nuclear-free future. Since 2011, voyages have included sessions on learning from Fukushima and, in 2014, they launched the Fukushima Youth Ambassadors program. This provides youth the opportunity to leave social pressures behind and learn about struggles people face all over the world, while also discovering more opportunities for their future. Students who joined as junior high students after the disaster are now in university and mentoring younger students. n January of 2012, in partnership with Greenpeace Japan (and others), Peace Boat organised the Global Conference on a Nuclear-Free World in Yokohama, to create a platform for a nuclear-free future and to build bridges between activists and ordinary citizens. An outcome of the Global Conference was the close collaboration between Peace Boat and the Fukushima Action Project (FAP), a local citizens’ group made up of residents and community leaders who have activated public engagement with government officials. The contents of the local nuclear power education center opened for school visits has been a focus point for dialogue. Some feedback has been incorporated, but given the gap in perspectives about nuclear power, FAP still works directly with the public. According to Joyce, an ongoing Peace Boat priority is to connect the local community to Tokyo and the international global community, so they support FAP by sharing access to the general public, international organizations and donors. The “Lessons from Fukushima” booklet, created by a group of organizations, including Peace Boat, has been translated into 14 languages. Reaching people in countries such as Turkey and Poland where the Japanese government has been promoting nuclear power is part of their global strategy. While the official stance is that Japan can provide the safest power due to the Fukushima experience, the booklet illustrates real experiences and impacts. Greenpeace Japan has been working with organizations such as Save the Children, Human Rights Now! and the Japan Bar Association to make the plight of people from Fukushima understood and have the voices of the people heard. They put pressure on the government by utilizing existing processes under international treaties and UN Human Rights systems. They have suggested new legislation in support of the victims such as free medical check-ups and treatment, radiation protection systems, establishment of the right to evacuate, dissemination of radiation protection information, participation of victims in decision making processes and the adaptation of UN principles for internally displaced persons. Both organisations have directly engaged policymakers and bureaucrats in dialogue on energy policy, but activating the public remains necessary. Suzuki explained that local activism has been important for keeping the restarts of power plants at bay. Joyce added that decisions to restart plants are at the local government levels, but they need our support here in the capital where the media is based and where national policy decisions are made. As this summer has shown, we do not know when the next disaster will strike and how our own lives may be affected, so we all need to get involved and not be under the false impression that everything is alright due to a lack of information. |

Japan will flush unsafe water from Fukushima nuclear plant into sea
https://www.independent.ie/world-news/asia-pacific/japan-will-flush-unsafe-water-from-fukushima-nuclear-plant-into-sea-37429128.html, Julian Ryall, October 17 2018 Water the Japanese government is planning to release into the Pacific Ocean from the crippled Fukushima nuclear plant contains radioactive material well above legally permitted levels, according to the plant’s operator.
The government is running out of space to store contaminated water that has come into contact with fuel that escaped from three nuclear reactors after the plant was destroyed in the March 2011 earthquake and tsunami that struck north-east Japan.
Its plan to release the approximately 1.09m tons of water stored in 900 tanks into the Pacific has triggered a fierce backlash from local residents and environmental organisations, as well as groups in South Korea and Taiwan fearful that radioactivity from the second-worst nuclear disaster in history might wash up on their shores.
Tokyo Electric Power Co (Tepco), which runs the plant, has until recently claimed the only significant contaminant in the water is safe levels of tritium, which can be found in small amounts in drinking water, but is dangerous in large amounts.
The government has promised that all other radioactive material is being reduced to “non-detect” levels by the sophisticated advanced liquid processing system (ALPS) operated by Hitachi Ltd.
Documents provided to ‘The Daily Telegraph’ by a source in the Japanese government suggest, however, that the ALPS has consistently failed to eliminate a cocktail of other radioactive elements, including iodine, ruthenium, rhodium, antimony, tellurium, cobalt and strontium.
Hitachi declined to comment on the reports on the performance of its equipment. The Japanese government did not reply to multiple requests for comment.
A restricted document also passed to ‘The Telegraph’ from the Japanese government arm responsible for responding to the Fukushima collapse indicates that the authorities were aware that the ALPS facility was not eliminating radionuclides to “non-detect” levels.
That adds to reports of a study by the regional ‘Kahoko Shinpo’ newspaper which said confirmed that levels of iodine 129 and ruthenium 106 exceeded acceptable levels in 45 samples out of 84 in 2017.
Iodine 129 has a half-life of 15.7 million years and can cause cancer of the thyroid; ruthenium 106 is produced by nuclear fission and high doses can be toxic and carcinogenic when ingested.
In late September, Tepco was forced to admit that around 80pc of the water stored at Fukushima still contains radioactive substances above legal levels after the Ministry of Economy, Trade and Industry held public hearings in Tokyo and Fukushima at which local residents and fishermen protested against the plans.
Tepco has now admitted that levels of strontium 90, for example, are more than 100 times above legally permitted levels in 65,000 tons of water that has been through the ALPS cleansing system and are 20,000 times above levels set by the government in several storage tanks at the site.
Dr Ken Buesseler, a marine chemistry scientist with the US Woods Hole Oceanographic Institution, said it was vital to confirm precisely what radionuclides are present in each of the tanks and their amounts.
“Until we know what is in each tank for the different radionuclides, it is hard to evaluate any plan for the release of the water and expected impacts on the ocean”, he told the ‘Telegraph’.
Experts agree the danger posed by any release depends on the concentrations of radionuclides and subsequent contamination of fishery products.
The presence of strontium in the bones of small fish that might be consumed by humans could be a major concern. If ingested by humans, strontium 90 builds up in teeth and bones and can cause bone cancer or leukaemia.
The nuclear industry’s deceptive narrative about Fukushima earthquake in March 2011
The status of “Station Blackout” is a serious one.
“it will be many years before the Japanese people know exactly what happened at Fukushima Daiichi on 11 March 2011. One of the key mysteries was role, if any, the magnitude 9 earthquake played in damaging the plant’s reactor cooling systems. Until lethal levels of radiation inside the reactors fall and workers can carry out comprehensive investigations, the truth about the tremor’s impact will remain a subject of conjecture and contention”
Mr. Takamatsu states with expert authority that the pipes of cooling system ware not designed for the 50 second vibration of the magnitude quake. Barry Brook, kangaroo expert, disagrees and tells the world the quake caused no damage at Fukushima. Yet Mr. Brook must surely know the earthquake caused grid blackout. For reactors are all shut down by earthquakes. A solar plant would have kept generating until the last panel shattered. No one would have been evacuated from such a solar plant.
I submit that Prof. Barry Brook’s description of the effects of earthquake upon the Fukushima Diiachi on 11 March 2011 is totally ignorant of the facts as presented by many qualified experts and fly in the face of the independent commission set up by the Japanese Parliament (Diet). It is confirmed that expert investigators concern aspects of TEPCO’s explanations regarding the quake are “irrational”.
Thus any narrative based upon the nuclear industry view, in line with TEPCO’s may fairly be said to be “irrational”. For the industry view is that there is no possibility of quake damage to any structure or sub structure, such as coolant pipes and valves.
Earthquake Damage At Fukushima – is Industry’s Narrative Truthful or Certain? Nuclear History, 16 Oct 18 I am again going to contrast the statements made by Barry Brook in regard to the events and outcomes at Fukushima Daiichi in 2011 with the facts as presented by Mark Willacy. These facts are published in Willacy’s book, “Fukushima – Japan’s tsunami and the inside story of the nuclear meltdowns”, Willacy, M., Pan Macmillan, copyright 2013, Mark Willacy.
However, I will also include information related to the events which were first published and discussed in 2011. ………..
The earthquake generated the tsunami. What else did the earthquake cause?
In this blog I have included posts which give the IAEA considerations for the electrical grids which are connected to nuclear power plants. The IAEA states that the level of engineering and resilience built into such grids may be a significant additional cost for any nation considering generation to nuclear power.
It comes as no surprise then the electrical grid connected to the Fukushima Daiichi NPP failed for two reasons. 1. The earthquake caused all the nuclear reactors connected to the same grid to rapidly shut down. Thus the earthquake caused a blackout due to cessation of electrical generation. 2. The physical grid infrastructure – poles and wires – were damaged by the earthquake. At Fukushima this meant that more than one of the reactors was physically separated from the grid by the earthquake.
It can therefore be seen that the earthquake meant A. Fukushima Diiachi could not generate nuclear electricity as the quake had shut the reactors down. B. The Fukushima Diiachi Nuclear Power Plant was in Station Blackout for one reason: earth quake damage to nuclear infrastructure – the electrical grid. Continue reading
Fukushima’s stored water still contains radioactive iodine, cesium and strontium, as well as tritium
Water stored at Fukushima nuclear plant still radioactive, https://abcnews.go.com/International/wireStory/water-stored-fukushima-nuclear-plant-radioactive-58147073 By MARI YAMAGUCHI, ASSOCIATED PRESS, The operator of Japan‘s wrecked Fukushima nuclear plant said Friday that much of the radioactive water stored at the plant isn’t clean enough and needs further treatment if it is to be released into the ocean.Tokyo Electric Power Co. and the government had said that treatment of the water had removed all radioactive elements except tritium, which experts say is safe in small amounts.
They called it “tritium water,” but it actually wasn’t.
TEPCO said Friday that studies found the water still contains other elements, including radioactive iodine, cesium and strontium. It said more than 80 percent of the 900,000 tons of water stored in large, densely packed tanks contains radioactivity exceeding limits for release into the environment.
TEPCO general manager Junichi Matsumoto said radioactive elements remained, especially earlier in the crisis when plant workers had to deal with large amounts of contaminated water leaking from the wrecked reactors and could not afford time to stop the treatment machines to change filters frequently.
“We had to prioritize processing large amounts of water as quickly as possible to reduce the overall risk,” Matsumoto said.
About 161,000 tons of the treated water has 10 to 100 times the limit for release into the environment, and another 65,200 tons has up to nearly 20,000 times the limit, TEPCO said………
TEPCO only says it has the capacity to store up to 1.37 million tons of water through 2020 and that it cannot stay at the plant forever.
Some experts say the water can be stored for decades, but others say the tanks take up too much space at the plant and could interfere with ongoing decommissioning work, which could take decades.
