The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Nobody knows what to do with Fukushima nuclear reactors’ corium – melted fuel

Fukushima – a Hushed Up Catastrophe, CounterPunch, by ROBERT HUNZIKER , OCTOBER 30, 2015 “……..As the situation now stands, what if the corium leaked or leaks into the ground beneath the reactor’s final cement & steel containment vessel, the last line of defense? Answer: Nobody knows because it has never happened before, but the smell test says it can’t be good; in fact, it’s gotta be awful, really awful and deadly out of control, impossible to stop.

Tragically, nobody knows what to do. They really don’t.

Still, here’s what sources claim probably happens when a nuclear meltdown hits pay dirt, immersing into Earth: Some isotopes uncontrollably spread erratically, for example, Cesiun-137, which is deadly toxic to all life forms, and only one of many dangerous isotopes, is water-soluble and makes its way into soils and waters and quickly becomes ubiquitous in the ecosystem; that’s what happens, “ubiquitous in the ecosystem.”

Thereafter, assuming a situation similar to Chernobyl (1986), an exclusion zone is established to keep everybody out due to excessive levels of radiation. But, questions like how big of an exclusion zone and how prolific the underground hot radioactive corium reacts nobody knows how to answer. When Ihor Gramotkin, director of the Chernobyl Power Plant was asked how soon the Chernobyl reactor site would be inhabitable again, he replied: “At least 20,000 years,” Eben Harrell, Apocalypse Today: Visiting Chernobyl, 25 Years Later, Time Magazine, April 26, 2011.

Nevertheless, the Abe government is already moving people back into some of the four-year-old exclusion zones of Fukushima………… http://www.counterpunch.org/2015/10/30/fukushima-a-hushed-up-catastrophe/

No foreseeable end to Fukushima’s daily dumping of radioactive waste to Pacific Ocean

Pacific-Ocean-drainFormer WHO Official: Fukushima plant is dumping nuclear waste into ocean on a daily basis; “There’s no foreseeable end to it… and nobody has any good ideas on how to stop it” — Japan gov’t worried that attempts to reduce leakage will cause even more radioactivity to flow into sea (VIDEO) http://enenews.com/former-official-fukushima-plant-dumping-radioactivity-ocean-daily-basis-foreseeable-good-ideas-stop-japan-govt-worried-attempts-stop-going-nuclear-waste-flow-sea-video?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29


Asahi Shimbun, Oct 26, 2015 (emphasis added): [TEPCO announced] the construction of seaside walls to block radiation-contaminated groundwater from seeping into the sea has been completed at the crippled Fukushima No. 1 nuclear power plant… TEPCO officials said the underground walls will reduce the daily flow of contaminated groundwater into the sea from the previous estimated 400 tons to 10 tons. However, they said it will take a month or two to confirm the effectiveness of the barriers.

Japan Times, Oct 26, 2015: Tepco hopes the wall will significantly reduce the amount ofcontaminated water that has continued to flow into the Pacific more than four yearsafter the 2011 meltdown crisis… 400 tons of groundwater was draining along the sides of the buildings and into the sea each day, after being contaminated with fallout from the 2011 meltdown crisis, according Tepco. The utility says an estimated 150 tons of underground water is still flowing into the basements of the damaged reactor buildings each day… Recent tests of water samples from the nearby sea have detected radioactive substances such as cesium-137 and strontium-90, but scientists have said the density is so low that it poses no immediate danger to human health. Yet, the ongoing flow of tainted water from the plant has raised anxiety and concerns among local fishermen and many consumers across the country. Tepco plans to keep monitoring the density of radioactive materials in the nearby sea over the next month. To isolate the four reactor buildings from the underground water, Tepco hopes to freeze the soil around them… The Nuclear Regulation Authority has yet to give permission for the operation, saying creation of frozen soil could drastically change the underground water level around the plant. If the water level outside falls lower than that inside, the contaminated water could leak out. Meanwhile, Tepco has not explained exactly how it will control the water levels, an NRA official said.

Dr. Keith Baverstock, former World Health Organization regional adviser for radiation and public health, published Oct 23, 2015 (at 37:00 in): “I’m really appalled at the way the international system has failed… Quite frankly, we don’t get anything through the media… There is no general understanding of the situation here in Europe, because the media are not putting this view forward. In fact, I think many people would be very surprised that it was still  a matter for discussion. They would be even more surprised to learn that it’s still an ongoing accident, and that it hasn’t terminated yet. They’d be even more surprised that nobody has any good ideas on how to stop it. So this is a very big black point… for the nuclear industry — that they can cause a situation like this, where there’s no foreseeable end to it. It’s against international law to dump radioactivity into the sea, but that is precisely what is happening on a daily basis.”

Japan’s govt admits that 40% of Fukushima evacuation personnel exposed to radiation of 1 mSv

text ionising40% of Fukushima evacuation personnel exposed to radiation of 1 mSv http://www.japantoday.com/category/national/view/40-of-fukushima-evacuation-personnel-exposed-to-radiation-of-1-msv OCT. 27, 2015 TOKYO — 

Nearly 40% of Self-Defense Forces troops, police officers and firefighters involved in evacuation operations right after the 2011 Fukushima nuclear crisis were exposed to radiation above the annual public limit of 1 millisievert, the government said Monday.

The Cabinet Office surveyed for the first time 2,967 personnel who assisted in evacuating residents living within a 20-kilometer radius of the Fukushima Daiichi nuclear complex as well as radiation cleanup and other activities from March 12 to 31, 2011.

The survey found that around 62% were exposed to radiation of less than 1 millisievert. But 38% were exposed to 1 millisievert or more, of whom 19% received 1 to 2 millisieverts and 5% received 5 to 10 millisieverts.

Daily radiation doses remained high until around March 15—the day the third reactor building suffered an explosion at the plant—and dropped below 0.1 millisievert from March 18.

The Cabinet Office revealed the data at a meeting to discuss ways to mitigate the radiation exposure of civilians helping others to evacuate in the event of a nuclear accident. The Japanese government is pushing for the reactivation of reactors that have cleared a set of new safety requirements imposed in the wake of the Fukushima crisis, triggered by a massive earthquake and tsunami on March 11, 2011, but public concern persists about whether smooth evacuations would be possible in the event of a nuclear accident.

The government plans to set a 1-millisievert-limit for civilians assisting in evacuations such as bus drivers. But some bus drivers are reluctant to accept the proposal.

The maximum radiation dose for ordinary members of the public is set at 1 millisievert per year. The limit for workers at nuclear facilities is 100 millisieverts over five years and 50 millisieverts per year in normal times, but it is raised in emergencies.

Use of the Tengrinews English materials must be accompanied by a hyperlink to en.Tengrinews.kz

Japanese Prime Minister Shinzo Abe has reiterated his country’s readiness to construct a nuclear power plant in Kazakhstan, Tengrinews.kz reports……

October 23 Tengrinews.kz reported, citing the country’s Vice Minister of Energy Bakhytzhan Dzhaksaliyev, that Kazakhstan was to decide within the following 2-3 years on the location and strategic partner for its first nuclear power station.

January 23,2015 Tengrinews.kz reported that Kazakhstan had started talks with Toshiba, owner of Westinghouse, to construct its first nuclear power plant. The sides were to sign an agreement on supplying a $3.7 billion reactor capable of 1 gigawatt, according to Russia’s Kommersant daily.

Early 2014 the country’s President Nursultan Nazarbayev commissioned the Government to decide before the end of the Q1 2014 on the location, sources of investments and timing of constructing a nuclear power plant in Kazakhstan.

In his Address to the Nation at the start of 2014, President Nursultan Nazarbayev elaborated why Kazakhstan needs to construct a nuclear power plant.

He emphasized that the future lies with nuclear power……… “The actual need for a nuclear power plant will be felt around 2025 given the current power generation and consumption figures”, he elaborated.

Japanese Prefecture Kyoto moves to replace nuclear with gas and renewables, in pact with Alaska

renewables-not-nukesflag-japanKyoto advances nuclear-free agenda with Alaska LNG pact, Japan Times, BY  KYOTO, 25 OCT 15,  – The Kyoto Prefectural Government signed an agreement with Alaska last month to explore the possibility of importing liquid natural gas from the state to Maizuru, a port city on the Sea of Japan.

While daunting financial and bureaucratic challenges mean it will still be a while before Alaskan LNG flows to Kyoto, the agreement represents a step forward for Kyoto to achieve a larger goal: ending prefectural dependence on nuclear power by 2040.

The strategy, as outlined by Kyoto Gov. Keiji Yamada, calls for building up LNG facilities at Maizuru and installing new LNG pipelines in the Kansai region. The prefecture envisions Maizuru supplying not only Kyoto, but other prefectures in the region with gas to replace Fukui Prefecture’s nuclear power plants as a major source of electricity.

Kyoto is not alone in seeking to replace atomic power with a combination of LNG imports and renewable energy.  As of the end of 2014, more than 600 local governments nationwide had declared their intent to be nuclear-free, although not all of have set specific dates like Kyoto, and many lack a strategic plan for achieving that goal.

Yamada listed several reasons why the prefecture needs to end its usage of nuclear power, which comes mostly from 11 Kansai Electric Power Co. reactors in neighboring Fukui……..

Kyoto and Hyogo, along with Osaka Gas, Kepco, and the Ministry of Economy, Trade and Industry, agreed in early September to formally research the cost of building an LNG pipeline from Maizuru to Sanda, Hyogo Prefecture, that could then supply other parts of Kansai and likely lead to other localities needing less nuclear power. http://www.japantimes.co.jp/news/2015/10/25/national/kyoto-advances-nuclear-free-agenda-alaska-lng-pact/#.Vi0_ztIrLGh

Many radiation related cancers to come, as Japan confirms Fukushima worker’s radiation caused cancer

“Thyroid cancer is commonly developed as a result of acute exposure to radioactive iodine 131, a product of nuclear fission…”

The British journalist also highlighted that the scientists have failed to mention that other radioactive elements emitted in the accident pose even more of a threat to the population’s health (in particular, 17.5 percent Cesium-137 and 38.5 percent Cesium 134).


text-relevantFukushima: Hundreds of Radiation-Related Cancer Cases on the Way in Japan, http://sputniknews.com/asia/20151023/1029014961/fukushima-radiation-cancer-threat-japan.html, 23 Oct 15  The Japanese government has recently admitted that a worker at the Fukushima nuclear plant contracted cancer as a consequence of radiation exposure of 2011, British journalist Oliver Tickell points out, warning that there are many more cases on the way.

cancer_cells The Japanese government has officially confirmed that a worker at the Fukushima nuclear plant has contracted radiation-related cancer: the man has been diagnosed with acute myelogenous leukaemia.

“But that single ‘official’ cancer case is just the beginning. New scientific research indicates that hundreds more cancers have been and will be contracted in the local population. A 30-fold excess of thyroid cancer has been detected among over 400,000 young people below the age of 18 from the Fukushima area,” British journalist, author and health and environment issue campaigner Oliver Tickell wrote in his article for The Ecologist, citing a report entitled “Thyroid Cancer Detection by Ultrasound Among Residents Ages 18 Years and Younger in Fukushima, Japan: 2011 to 2014.”

The highest incidence rate ratio, using a latency period of 4 years, was observed in the central middle district of the prefecture compared with the Japanese annual incidence (incidence rate ratio = 50; 95% confidence interval [CI] = 25, 90),” the report read.

Tickell noted that during a first screening for thyroid cancer held four years after the Fukushima catastrophe among 298,577 youths, the disease was registered 50 times more frequently among those who lived in the most heavily irradiated zones than among other Japanese youth.

During a second screening carried out in April 2014 among 106,068 young people who lived in less contaminated areas of the Fukushima prefecture, the disease was 12 times more common than for the main population.

“Thyroid cancer is commonly developed as a result of acute exposure to radioactive iodine 131, a product of nuclear fission. Because iodine concentrates in the thyroid gland, thyroid damage including cancer is a characteristic marker of exposure to nuclear fallout,” Tickell elaborated, adding that iodine-131 constituted about 9.1 percent of the radioactive material released during the Fukushima disaster.

Quoting the report, Tickell called attention to the fact that “the incidence of thyroid cancer is high by comparison with the Chernobyl nuclear disaster in 1986,” beating the drums over the possibility of a growing cancer threat in the region in the next four-five years.

That is not all, the British journalist added, emphasizing that the real exposure doses for residents could have been higher than had been reported by the authorities and the World Health Organization.

“We could infer a possibility that exposure doses for residents were higher than the official report or the dose estimation by the World Health Organization, because the number of thyroid cancer cases grew faster than predicted in the World Health Organization’s health assessment report,” the authors of the report underscored, as quoted by Tickell.

The British journalist also highlighted that the scientists have failed to mention that other radioactive elements emitted in the accident pose even more of a threat to the population’s health (in particular, 17.5 percent Cesium-137 and 38.5 percent Cesium 134).

“These longer-lived beta-emitters (30 years and two years respectively) present a major long-term hazard as the element is closely related to potassium and readily absorbed into biomass and food crops,” Tickell stressed.

The author bemoaned the fact the Japanese people also face a danger posed by “long lived alpha emitters like plutonium 239 (which has a half-life of 24,100 years) which is hard to detect.”

“Even tiny nano-scale specks of inhaled plutonium entering the lungs and lymphatic system can cause cancer decades after the event by continuously ‘burning’ surrounding tissues and cells,” Oliver Tickell warned.

Fukushima worker’s leukaemia confirmed as caused by radiation

cancer_cellsflag-japanFukushima worker diagnosed with leukaemia after shocking radiation leak at nuclear plant, news.com.au OCTOBER 20, 2015 A FORMER Fukushima nuclear plant worker has been diagnosed with radiation-linked cancer, making him the first such confirmation more than four years after the worst atomic accident in a generation.

An official with the health ministry said the ex-employee, who was in his thirties while working at the plant following the 2011 crisis, has developed leukaemia. He is now 41 years old, local media reported.

“The case has met the criteria” to link his illness to the accident, the official told a Tokyo press briefing on condition of anonymity, adding that other possible causes have been ruled out.

“This person went to see a doctor because was not feeling well. That was when he was diagnosed with leukaemia.” The ministry revealed few details about the man, but said he had worked at a destroyed building that housed one of the crippled reactors.

The man, who wore protective equipment during more than a year spent at Fukushima, will be awarded compensation to pay for his medical costs and lost income, the official said, without elaborating on the amount.

Three similar cases of cancer in plant workers are still awaiting confirmation of a link to the accident…….

The announcement Tuesday will likely further inflame widespread public opposition to nuclear power……..

The case was likely to deal another blow to Prime Minister Shinzo Abe’s unpopular attempt to switch on Japan’s stable of atomic reactors………http://www.news.com.au/world/asia/fukushima-worker-diagnosed-with-leukaemia-after-shocking-radiation-leak-at-nuclear-plant/story-fnh81fz8-1227576166328

The public recognition of a radiation-cancer threat may lead to high compensation payments

cancer_cellsflag-japanJapan Acknowledges First Possible Radiation Casualty at Fukushima Nuclear Plant The public recognition of a radiation-cancer threat may lead to high compensation payments  TOKYO, Oct 20 (Reuters) – Japan on Tuesday acknowledged the first possible casualty from radiation at the wrecked Fukushima nuclear power plant, a worker who was diagnosed with cancer after the crisis broke out in 2011.

The health ministry’s recognition of radiation as a possible cause may set back efforts to recover from the disaster, as the government and the nuclear industry have been at pains to say that the health effects from radiation have been minimal.

It may also add to compensation payments that had reached more than 7 trillion yen ($59 billion) by July this year…….

The male worker in his 30s, who was employed by a construction contractor, worked at Tokyo Electric Power Co’s Fukushima Daiichi plant and other nuclear facilities, a health ministry official said.

Of total radiation exposure of 19.8 millisieverts (mSv), the worker received a dose of 15.7 (mSv) between October 2012 and December 2013 working at Fukushima, said the official.

While the exposure amount was lower than the annual 50 mSv limit for nuclear industry workers, the government had decided it cannot be ruled out that the worker’s leukaemia was a result of radiation, the official said.

Tokyo Electric is also facing a string of legal cases seeking compensation over the disaster.

Inside the plant, Tepco has struggled to bring the situation under control. It is estimated removing the melted fuel from the wrecked reactors and cleaning up the site will cost tens of billions of dollars and take decades to complete.

Fukushima insect study shows there is no safe low level of ionising radiation

Butterfly-grass-blue-mutateThe researchers found that caterpillars that ate radioactive leaves pupated into mutated butterflies that did not live as long, compared with caterpillars that ate non-radioactive leaves. These mutations and increased mortality were seen even in butterflies that consumed only very small doses of radioactive cesium.
 Deaths and mutations spike around Fukushima;  October 16, 2015 by: David Gutierrez, staff writer
http://www.naturalnews.com/051581_fukushima_radiation_nuclear_power.html

Plants in the area around Fukushima, Japan are widely contaminated with radioactive cesium, which is Cesium-137
producing mutation and death in local butterflies, according to a study conducted by researchers from the University of the Ryukyus, Okinawa and published in the journal Scientific Reports.

The butterflies were found to experience severe negative effects at all detectable radiation levels, even very low ones.

“We conclude that the risk of ingesting a polluted diet is realistic, at least for this butterfly, and likely for certain other organisms living in the polluted area,” the researchers wrote.

Insects hard hit

The researchers note that although the 2011 meltdown of the Fukushima Daiichi Nuclear Power Plant released “a massive amount of radioactive materials … into the environment,” few studies have looked at the biological effects of this disaster. Researchers have, however, measured elevated radiation levels in the polluted area, and have chronicled the accumulation of radioactive material in both wild and domestic plant and animal life in the region.

Studies have also suggested that insects may be particularly hard-hit by the increased radiation. One study found an increase in morphological abnormalities (physical deformities) in gall-forming aphids. Another found that insect abundance has decreased in the affected region, particularly butterfly abundance. Continue reading →

Concerns over Japan’s huge stockpile of weapons grade nuclear material

safety-symbol-Smflag-japanChina calls on Japan to address world concerns on excessive nuclear stocks http://news.xinhuanet.com/english/2015-10/15/c_134717556.htm BEIJING, Oct. 15 (Xinhua) — China on Thursday called for action from Japan to defuse concerns over its excess of nuclear materials as both Chinese and U.S. think tanks expressed worry in recent reports.

“The international community has always been concerned about Japan’s stockpile of enriched uranium and the risks relating to nuclear proliferation and safety,” Foreign Ministry spokesperson Hua Chunying said.

“The reports suggest there are ways to resolve the surplus nuclear material issue,” she said at a regular news briefing, calling on Japan to be responsible and act to address the international community’s concerns.

The stockpile puts Japan, its neighbors and the world at risk, a joint study by China Arms Control and Disarmament Association and the China Institute of Nuclear Information and Economics said on Friday.

“If, in future, a different country started to stockpile — could be enriched uranium, it could be plutonium — that country could cite Japan as a precedent,” said James Acton, author of a new report on Japan’s reprocessing policy at the Carnegie Endowment for International Peace think tank.

The Chinese study suggests Japan should make a rational plan for its nuclear consumption and address the imbalance, while ensuring the safety and security of these materials.

Citing the latest data from the Japanese government submitted to the International Atomic Energy Agency (IAEA), the Chinese study found Japan has 47.8 tonnes of highly sensitive separated plutonium, 10.8 tonnes of which are stored in Japan, enough to make 1,350 nuclear warheads.

No evacuation plan, yet PM Abe restarts another Sendai nuclear reactor

Last year, Prime Minister Shinzo Abe said he would not allow a reactor startup unless its safety is completely confirmed.  But the process of approving reactor restarts at the Sendai nuclear power plant has not been in line with his pledge at all

 sendai 2Safety put on the back burner as another nuclear reactor is restarted, Asahi Shimbun, 14 Oct 15  Kyushu Electric Power Co. is set to restart the No. 2 reactor at its Sendai nuclear power plant in Satsuma-Sendai, Kagoshima Prefecture, on Oct. 15. In August, the plant’s No. 1 reactor became the first to resume operations under new safety regulations that went into force in July 2013.

Some areas near the plant may not even have a dependable evacuation route in the event of a disaster. Furthermore, no evacuation drills for residents have been undertaken.

The electric utility’s plan to restart the idled reactor was given the green light by the Nuclear Regulation Authority. The nuclear watchdog body has no authority, however, to examine evacuation plans.

A reactor should not be restarted under such circumstances. Continue reading →

Second nuclear reactor started at Sendai, despite public opposition

sendaiJapan restarts second nuclear reactor despite public opposition, Guardian, 15 Oct 15
Number-two reactor at Sendai has gone on line more than four years after a quake-sparked tsunami swamped a plant at Fukushima. Japan on Thursday restarted a second nuclear reactor after a shutdown triggered by the 2011 Fukushima crisis, as the government pushes to return to a cheaper energy source despite widespread public opposition.

Utility Kyushu Electric Power said it restarted the number-two reactor at Sendai, about 1,000 kilometres (620 miles) southwest of Tokyo at 10.30am (0130 GMT).

The same power plant’s number-one reactor was restarted in August, ending a two-year nuclear power hiatus. Engineers will now spend several days bringing the newly restarted reactor up to operational level before running it commercially from November…….

But the public is largely opposed to atomic energy after the Fukushima crisis sent radiation over a wide area and forced tens of thousands from their homes – many of whom will likely never return – in the worst nuclear accident since Chernobyl in 1986…….http://www.theguardian.com/world/2015/oct/15/japan-restarts-second-nuclear-reactor-despite-public-opposition

Continuing struggle to rid Okinawa of USA military bases

Struggle against U.S. bases continues in Okinawa http://happening-here.blogspot.com.au/ The elected governor of the Japanese-controlled island of Okinawa has said no, again, to further construction of a new U.S. base. Okinawans have been trying to reclaim their territory for decades. The island is part of the Ryukyu archipelago which the U.S. conquered at the end of World War II. Japan recovered sovereignty, but although since 1945 Japan has been ostensibly a nuke-free zone, the U.S. has been allowed to bring nuclear armed vessels to Okinawa if not the Japanese mainland.

The 1.3 million Okinawans have repeatedly elected officials who promise to oust the U.S. military. These local officials have then been overruled from Tokoyo repeatedly.

The U.S. Marines are not considered good neighbors on the island: they are seen as the source of drunken louts and rapists who usually enjoy impunity from the local justice system.

Between 1972 and 2009, U.S. servicemen committed 5,634 criminal offenses, including 25 murders, 385 burglaries, 25 arsons, 127 rapes, 306 assaults and 2,827 thefts. The government of Japan, currently in a phase of newly assertive nationalism, appreciates living under the US. security umbrella, especially since they have offshored the basing tensions.

Okinawans are Japan’s largest minority group.

I have written previously about Okinawa’s special place and its irritants to the U.S. empire here and here.

Anxious about 2020 Olympics, Tepco to hasten ice wall project at Fukushima nuclear station

logo-Tokyo-OlympicsTepco Expects to Begin Freezing Fukushima Ice Wall by Year End http://www.bloomberg.com/news/articles/2015-10-10/tepco-expects-to-begin-freezing-fukushima-ice-wall-by-year-end  Stephen Stapczynski  October 10, 2015

  • Aim to resolve contaminated water issue by 2020 Olympics
  • About 300 tons of water a day flow into radioactive reactor

 

ice wall

  • Tokyo Electric Power Co. expects to begin freezing a soil barrier by the end of the year to stop a torrent of water entering the wrecked Fukushima nuclear facility, moving a step closer to fulfilling a promise the Japanese government made to the international community more than two years ago.

    “In the last half-year we have made significant progress in water treatment,” Akira Ono, chief of the Fukushima Dai-Ichi plant, said Friday during a tour of the facility north of Tokyo. The frozen wall, along with other measures, “should be able to resolve the contaminated water issues before the Olympic games.”

    Solving the water management problems would be a major milestone, but Tokyo Electric is still faced with a number of challenges at the site. The company must still remove highly radioactive debris from inside three wrecked reactors, a task for which no applicable technology exists. The entire facility must eventually be dismantled.

  • Currently, about 300 metric tons of water flow into the reactor building daily from the nearby hills. Tepco, as the nation’s biggest utility is called, has struggled to decommission the reactors while also grappling with the buildup of contaminated water.

    Even four years after the meltdown and despite promises from policymakers, water management remains one of Tepco’s biggest challenges in coping with the fallout of Japan’s worst nuclear disaster.

    The purpose of the ice wall — a barrier of soil 30 meters (98 feet) deep and 1,500 meters long which is frozen to -30 Celsius (-22 Fahrenheit) — is to prevent groundwater from flooding reactor basements and becoming contaminated.

  • Public Trust Needed

    “As the radiation levels decrease via natural decay, water management becomes the main issue,” Dale Klein, an independent adviser for Tepco and a former chairman of the U.S. Nuclear Regulatory Commission, said by e-mail. “It is a very important issue for the public, and good water management is needed for Tepco to restore the public’s trust.”

  • Tepco is currently testing the freezing system, aiming to have the fence fully operational by the end of December, company spokesman Yuichi Okamura said.

    At the moment, the deluge of groundwater entering the reactor buildings is purified, lowering its radioactive content. The water is then stored in one of numerous barrels at the site, each of which can hold 1,000 tons of water.

    To make room for the 1,000 or so barrels required to hold the water, Tepco flattened a 500 square meter (5,382 square foot) bird sanctuary on the outskirts of the facility. The company doesn’t have government approval to release the water into the ocean, and there’s no clear plan for its disposal, Tepco’s Okamura said.

  • Prime Minister Shinzo Abe promised in 2013 that the government would take the lead in resolving the water management issues at the Fukushima site ahead of the 2020 Tokyo Olympics. Two years later, hundreds of tons of water continue to pour into the reactor building, while tainted water at other parts of the site overflows into the ocean.

    Water Overflow

    Since January, slightly tainted water has spilled from a drainage system into the ocean on nine occasions, according to company spokeswoman Yukako Handa.

    The company aims to end these leaks by reconfiguring a drainage system and building a wall running 30 meters into the seabed. The drainage work will be completed next year, and the sea wall will be completed this month.

    The proposed ice wall has never been done on such a scale, and there could be operational issues due to the complicated nature of the project, according to Lake Barrett, former head of the U.S. Department of Energy’s Office of Civilian Nuclear Waste Management.

    “Some of these areas may have different freezing and sealing capabilities,” he said by e-mail. “These types of problems were encountered when Tepco tried and failed to seal the seawater trenches by freezing.”
