Sediment Sampling at Lake Biwa in Japan: Mai Suzuki from Greenpeace Japan, removes sediment samples from the ROV grabber (Remote Operated Vehicle), at Lake Biwa. Greenpeace has been surveying lake Biwa to conduct baseline sampling. The lake is located as close as 30 km from the Takahama nuclear plant owned by Kansai Electric. In the event of a severe accident Lake Biwa would be at risk of major radioactive contamination. The lake provides the drinking water for 14,5 million people in Shiga Prefecture, the city of Kyoto and the wider Kansai region. The citizens of Shiga recently won a historic legal action that forced the immediate shutdown of Takahama reactor #3, Kansai electric is determined to overturn the legal action on appeal and restart both Takahama 3 and 4 reactor.

Tokyo, 21 July 2016 – Radioactive contamination in the seabed off the Fukushima coast is hundreds of times above pre-2011 levels, while contamination in local rivers is up to 200 times higher than ocean sediment, according to results from Greenpeace Japan survey work released  today.

“The extremely high levels of radioactivity we found along the river systems highlights the enormity and longevity of both the environmental contamination and the public health risks resulting from the Fukushima disaster,” said Ai Kashiwagi, Energy Campaigner at Greenpeace Japan.

“These river samples were taken in areas where the Abe government is stating it is safe for people to live. But the results show there is no return to normal after this nuclear catastrophe,” said Kashiwagi.

Riverbank sediment samples taken along the Niida River in Minami Soma, measured as high as 29,800 Bq/kg for radiocaesium (Cs-134 and 137). The Niida samples were taken where there are no restrictions on people living, as were other river samples. At the estuary of the Abukuma River in Miyagi prefecture, which lies more than 90km north of the Fukushima Daiichi plant, levels measured in sediment samples were as high as 6,500 Bq/kg.

The lifting of evacuation orders in March 2017 for areas that remain highly contaminated is a looming human rights crisis and cannot be permitted to stand. The vast expanses of contaminated forests and freshwater systems will remain a perennial source of radioactivity for the foreseeable future, as these ecosystems cannot simply be decontaminated.

Caesium-137 has a half life of 30 years, and will continue to pose a risks to the the environment and human health for hundreds of years. Cs-137 contamination in seabed samples near the Fukushima plant was measured at up to 120 Bq/kg – compared to levels pre-2011 of 0.26 Bq/kg. Further, the levels of contamination found 60km south of the Fukushima Daiichi nuclear plant were comparable with those found within 4km of the plant. Numerous marine science investigations, have concluded that these higher levels are one explanation for some marine species still showing higher cesium levels than the background levels in seawater.

“The radiation levels in the sediment off the coast of Fukushima are low compared to land contamination, which is what we expected and consistent with other research,” said Kendra Ulrich, Senior Global Energy Campaigner at Greenpeace Japan. “The sheer size of the Pacific Ocean combined with powerful complex currents means the largest single release of radioactivity into the marine environment has led to the widespread dispersal of contamination.”

Most of the radioactivity in Fukushima Daiichi reactor units 1-3 core fuel in March 2011 remains at the site.

“The scientific community must receive all necessary support to continue their research into the impacts of this disaster,” said Ulrich.

“In addition to the ongoing contamination from forests and rivers, the vast amount of radioactivity onsite at the destroyed nuclear plant remains one of the greatest nuclear threats to Fukushima coastal communities and the Pacific Ocean. The hundreds of thousands of tonnes of highly contaminated water, the apparent failure of the ice wall to reduce groundwater contamination, and the unprecedented challenge of three molten reactor cores all add up to a nuclear crisis that is far from over,” said Ulrich.

A radiation survey team onboard the research vessel Asakaze, supported by the Greenpeace flagship Rainbow Warrior, conducted underwater survey work along the Fukushima coastline from 21 February to 11 March this year, as well collecting samples in river systems. The samples were measured at an independent laboratory in Tokyo.

Greenpeace reports jump in radioactive contamination in Fukushima waterways

n-greenpeace-a-20160722-870x581

Greenpeace Japan member Mai Suzuki removes sediment samples from a remotely operated grabber at Lake Biwa in Shiga Prefecture on March 22.

OSAKA – Greenpeace Japan on Thursday said it has discovered radioactive contamination in Fukushima’s riverbanks, estuaries and coastal waters at a scale hundreds of times higher than pre-2011 levels.

One sample of sediment taken along the Niida River, less than 30 km northwest of the crippled Fukushima No. 1 power plant, revealed the presence of cesium-134 and cesium-137 at levels of 29,800 becquerels per kilogram.

That was just one of 19 samples of dried sediment and soil the environmental activist group took and analyzed from the banks of the Abukuma, Niida, and Ota rivers. The samples were collected by Greenpeace in February and March.

All of the samples but one exhibited more than 1,000 Bq/kg of radioactive material. The lowest level, 309 Bq/kg, was logged at a spot along the Abukuma River.

Cesium-134 has a half-life of about two years, but cesium-137 has a half-life of 30 years and is considered particularly hazardous. The standard limits set for radioactive cesium in Japan are 100 Bq/kg for general foods and 10 Bq/kg for drinking water.

“The radiological impacts of the Fukushima nuclear disaster on the marine environment, with consequences for both human and nonhuman health, are not only the first years. They are both ongoing and future threats, principally the continued releases from the Fukushima No. 1 plant itself and translocation of land-based contamination throughout Fukushima Prefecture, including upland forests, rivers, lakes and coastal estuaries,” the report said.

Greenpeace Japan also published the results of tests on dried marine sediment samples collected at 25 points off the Fukushima coastal area, including three river estuaries, during this same period, at depths of between 7.4 and 30.6 meters. The results showed that the highest level of cesium was 144 Bq/kg taken from a sample collected off the coast from the Fukushima power plant, while the lowest total cesium figure was 6.5 Bq/kg off Nakanosaku, well to the south of the plant.

In addition to Fukushima, Greenpeace Japan took dried sediment samples from Lake Biwa at three locations near the shore. The results showed cesium levels to be between 7.1 Bq/kg and 13 Bq/kg at two locations, and negligible at the other two.

The safety of Lake Biwa, which provides drinking water for about 14 million people in the Kansai region, has become a major bone of contention between Kansai Electric Power Co., which wants to restart reactors in neighboring Fukui Prefecture, and residents in and around Lake Biwa who are fighting to keep them shut down.

Glass Encapsulated Insoluble Cesium Particles Lodged in the Fukushima Workers Lungs

dfghjkl.jpg

 

 

 

A study published in March of 2016 found insoluble cesium lodged in the lungs of some of the highly exposed Fukushima disaster response workers. After doing additional scans they found most of that persistent cesium contamination resided in the workers lungs.

Direct measurements of seven highly exposed workers at the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Station accident have been performed continuously since June2011.

Caesium clearance in the monitored workers is in agreement with the biokinetic models proposed by the International Commission on Radiological Protection. After 500 days from the initial measurement, however, the caesium clearance slowed.

It was thought to be unlikely that additional Cs intake had occurred after the initial intake, as activity in foods was kept low. And, the contribution from the detector over the chest was enhanced with time. This indicates that insoluble Cs particles were inhaled and along metabolic rate showed.


The study concludes that insoluble cesium particles lodged in the workers lungs, preventing them from leaving the body through normal processes.


“The subjects seem to have inhaled insoluble caesium particles, even though it was only a small amount. At present, it is more plausible that the retention curves reported here were due to inhalation of a mixture of type F caesium (soluble particle) and type S caesium (insoluble particle).”


This finding is significant as it shows how the various kinds of insoluble radioactive cesium materials discovered after the initial disaster, both black substances and the glass spheres could contaminate the human body.

TEPCO ordered to pay for rumor-caused damages

A Japanese court has ordered Tokyo Electric Power Company, or TEPCO, to compensate a golf course operator for damages caused by rumors after the Fukushima Daiichi nuclear accident in 2011.

This is the first ruling in Japan that recognizes rumor-caused damages related to a nuclear accident.

The golf course operator’s suit claimed that revenues from its course in Tochigi Prefecture, north of Tokyo, dropped due to harmful rumors related to the nuclear accident.

TEPCO argued that there was no danger from radiation because the golf course is more than 100 kilometers from the nuclear plant.

In the ruling on Wednesday, Tokyo District Court Judge Tetsuro Nakayoshi said the public did not have sufficient knowledge about radiation around the time of the accident.

He noted that it was not unreasonable for ordinary people to worry about health risks.

The court determined that harmful rumors were responsible for 30 to 50 percent of the decline in revenue for more than 5 months following the accident.

The court ordered the utility to pay about 180,000 dollars in compensation.

TEPCO says the company will deal with the matter sincerely after studying the ruling.

Reactor decommissioning plan revised

20160720_32_171045_L.jpg

 

A Japanese government body has revised its plan to decommission the reactors at the Fukushima Daiichi nuclear plant in response to local opposition.

The revision ruled out the option of adopting a Chernobyl-style “sarcophagus” method that seals off disabled reactors with nuclear fuel inside.

The Nuclear Damage Compensation and Decommissioning Facilitation Corporation released the revised plan on Wednesday.

The body presented a technical report a week ago that mentioned the possibility of adopting the sarcophagus method for the first time, while saying it remained committed to removing fuel debris from the reactors.

The report faced backlash from the people in Fukushima Prefecture. Economy, Trade and Industry Minister Motoo Hayashi instructed the body to revise the plan.

The word “sarcophagus” has been deleted from the revised plan, which states that the method will not be adopted in the decommissioning process at the plant.

Shunsuke Kondo, the head of the body’s technical committee, says he regrets the body’s lack of consideration for the locals.

He said he will make sure the body communicates with the locals properly and places top priority on their thoughts.

Fukushima Governor Masao Uchibori said he wants the body to realize how shocked the Fukushima residents were with the word “sarcophagus.”

He said he wants the body to proceed with the removal of fuel debris from the reactors in a safe manner, in line with the locals’ desires.

In first, Tepco admits ice wall can’t stop Fukushima No. 1 groundwater

june 30 2016.jpg

 

The much-hyped ice wall at the crippled Fukushima No. 1 nuclear power plant has failed to stop groundwater from flowing in and mixing with highly radioactive water inside the wrecked reactor buildings, operator Tokyo Electric Power Co. Holdings Inc. has admitted.

Tepco officials also said at a meeting of the Nuclear Regulation Authority in Tokyo that it is not the utility’s ultimate goal to shut out groundwater with the ice wall, which has been built around the four damaged reactor buildings at the plant.

Tuesday’s announcement was apparently the first time the utility publicly said it is technically incapable of blocking off groundwater with the frozen wall.

Five years after the March 2011 quake and tsunami triggered the nuclear crisis, Tepco continues to be plagued by radiation-tainted groundwater, mostly rainwater that is mixing with contaminated water in the basement of the damaged reactor buildings.

In response, Tepco has completed most of the 1.5-km-long sunken wall of frozen soil around the stricken reactors to keep groundwater out. It has also built “subdrain” wells around the buildings to pump up the tainted groundwater for treatment and ultimate discharge into the Pacific.

While the completed sections of the ice wall began operating in March, it has not made a visible impact in reducing the amount of groundwater inflows. According to Tepco, the amount of groundwater pumped up from subdrains averaged 321 tons per day in June, just 31 tons less than the daily average in May.

Asked whether Tepco plans to eventually block rainwater from seeping through the ice wall, a Tepco official said it is not technically feasible “to keep out the groundwater 100 percent,” according to a video of the meeting released Tuesday by the NRA.

“We are aiming to control the amount of water going into the reactor buildings, with the ice wall and subdrains,” said Tomohiko Isogai, an official in charge of dismantling the plant.

Kiyoshi Takasaka, a nuclear expert at the Fukushima Prefectural Government, said it was the first time he had heard such a comment from Tepco, pressing the firm on whether it marked a “change of policy.”

A Tepco official denied this, saying that while it wants to “close off the wall as much as possible,” its ultimate goal has been to “curtail” groundwater inflow, not halt it.

Also at the meeting, NRA acting head Toyoshi Fuketa demanded that Tepco move quickly to reduce the amount of highly radioactive water inside the reactor buildings, saying such water presents the risk of escaping in the event of another monster tsunami. Some 60,000 tons of highly tainted water remain in the leaking basements of reactor buildings 1, 2, 3 and 4.

“We want the amount of (radioactive water) inside the buildings to be reduced as much as possible,” he said.

Tokyo jolted by third quake in four days

japan-quake
Tokyo was struck by a third quake in four days on Jul 20, but there were no reports of damage or casualties.
1884361

TOKYO – Tokyo was struck by a third earthquake in four days on Wednesday, but there were no reports of damage or casualties.

The 5.0 magnitude jolt was felt in Tokyo and areas of eastern Japan at 7.25am (5.25am Thailand time), the US Geological Survey said.

It was the third quake to shake the capital’s high-rise buildings in recent days — following a 4.8 magnitude quake on Tuesday and one of 5.0 on Sunday — but an official with the Japan Meteorological Agency said they weren’t a precursor of a major jolt.

“This is an area that sees frequent earthquakes” of a moderate size, Nariaki Ohkawara told AFP, adding that the latest quakes were part of that trend.

The epicentre of Wednesday’s quake was east of the capital in Ibaraki prefecture at a depth of about 44 kilometres, the USGS said.

There was no threat of a tsunami, the Japan Meteorological Agency said.

Japan sits at the junction of four tectonic plates and experiences a number of relatively violent quakes every year, but rigid building codes and strict enforcement mean even powerful tremors frequently do little damage.

A massive undersea quake that hit in March 2011 sent a tsunami barrelling into Japan’s northeast coast, leaving more than 18,000 people dead or missing, and sending three reactors into meltdown at the Fukushima nuclear plant.

In April, two strong earthquakes hit southern Japan’s Kumamoto prefecture followed by more than 1,700 aftershocks, and left 49 dead and caused widespread damage.

The country routinely holds emergency drills to prepare for a major jolt, and the government stepped up its disaster response in the wake of the 2011 devastation.

Cochin International Airport in Kerala, India powered entirely by solar energy

sunflag-indiaThanks to solar power, this airport is no longer paying for electricity. https://www.weforum.org/agenda/2016/07/thanks-to-solar-power-this-airport-is-no-longer-paying-for-electricity/  Jenny Soffel Website Editor, World Economic Forum 19 July 2016 [excellent graphs]   If you fly over Cochin International Airport in Kerala, India, you will find yourself staring down at over 46,000 solar panels. The airport, India’s seventh busiest, last year became the first airport in the world to run completely on solar power.

It started as a pilot project in 2013 with 400 panels on the airport rooftop, an attempt by management to lower the airport’s energy bills. After the installation of a 12 megawatt solar plant, the airport was able to run entirely on solar power.

The airport has now stopped paying for its electricity altogether, and even sends energy back to the grid.

Solar energy has become a cheap option in India – the price has dropped to a similar level to that of coal.

India’s Prime Minister Narendra Modi has said the country’s investment target for the source of renewable energy will be increased to $100 billion, five times greater than current levels, scaling solar power to more than 10% of India’s total energy sector by 2022.

The successful project has inspired other airports both nationally and internationally to invest in renewable energy. Kolkata’s international airport in India is now also looking to build a solar plant to reduce its electric bill by a third.

South Africa recently opened the continent’s first solar-powered airport in George, in the Western Cape. It’s expected to save an excess of 1.2 million litres of water every year, and will contribute to around 40% of the airport’s electricity needs.

James Fisher Nuclear Awarded Fukushima Daiichi Sampling Contract

Fukushima worker pointing.jpg-320x240

British decommissioning and remote handling company James Fisher Nuclear announced Monday that it had been awarded a “high-value” contract from Japanese engineering company Mitsubishi Heavy Industries that involves developing technology to be used at the Fukushima Daiichi Nuclear Power Plant in Okuma, Japan.

JFN will be responsible for developing the latest technology to sample radioactive debris sitting below reactor cores at the power plant that suffered a triple reactor meltdown after backup power failed due to a massive tidal wave event in March 2011.

The specific value of the contract was not announced. JFN said it beat out the competition for the contract. Business director at JFN Bertie Williams said the expertise required for this kind of assignment was rare. “Few businesses in the nuclear arena realistically have the experience and personnel with the capabilities to take on such a challenging task,” Williams said.

The work involves taking samples of a variety of materials both above and below the water line at the damaged plant. JFN said it had been successful in demonstrating its technical design was “capable of addressing some of the most challenging conditions on Earth.” The goal is to evaluate the extent of the clean-up and decommissioning work needed at the plant.

Fukushima residents need time in deciding on their futures

evacuation.jpg

 

 

The central government lifted an evacuation order for the southern part of Minami-Soma, Fukushima Prefecture, on July 12 for the first time since the massive earthquake and tsunami triggered a devastating accident at the Fukushima No. 1 nuclear power plant in March 2011.

It marks the sixth time that evacuation orders have been lifted for locales in Fukushima Prefecture, following such municipalities as Naraha and Katsurao. The number of local residents affected by the latest move is more than 10,000, higher than in any previous instance.

Residents of such municipalities in the prefecture as Iitate, Tomioka and Namie have yet to be allowed to return to their homes. But the central government plans to lift evacuation orders on all areas of the prefecture excluding “difficult-to-return zones,” where levels of radiation remain dangerously high, by March 2017.

The longer people in disaster-affected areas live as evacuees, the more difficult it becomes for them to rebuild their lives.

The lifting of an evacuation order based on the progress that has been made in decontaminating polluted areas and restoring damaged infrastructure will give local residents an opportunity for a fresh start. In Minami-Soma, residents who have been hoping to restart their former lives have already returned to their homes. Various organizations are expanding their activities in the city to help rebuild the local communities.

In previous cases, however, only 10 to 20 percent of the residents said they would immediately return to where they lived before the catastrophic accident occurred.

In addition to residents who have decided to move to other parts of the nation, there are also many people who find it difficult to return home for the time being due to reasons related to employment, education, nursing care and other factors. Some people want to wait a while longer to see how their communities will be revived.

Sooner or later, all evacuees will face the choice of returning or migrating.

For both groups, measures to support their efforts to rebuild their livelihoods should be worked out. But support should also be provided to people who cannot make up their minds yet.

A situation where evacuees are under strong pressure to make their decisions quickly should be avoided.

Take the issue of compensation paid to local residents in affected areas, for example. Tokyo Electric Power Co., the operator of the crippled Fukushima nuclear plant, is paying 100,000 yen ($945) of compensation per month to each of the people affected. But the utility’s cash payments are scheduled to be terminated in March 2018.

A time limit has also been set for the company’s compensation to people who have seen their incomes fall or disappear in the aftermath of the disaster.

Excessive dependence on compensation could hamper the efforts of evacuees to restart their lives.

But there are people who have no prospects of returning to their lives before the accident and therefore have no choice but to depend entirely on a monthly payment from the utility.

A way should be found to keep compensating those who really need the money for a certain period after evacuation orders are lifted, according to the circumstances of individual evacuees.

One idea worth serious consideration is the establishment by lawyers and other experts of a neutral organization to assess the circumstances of evacuees for this purpose. This is an approach modeled on the standard procedures for out-of-court dispute settlements.

The concept of “residents” should also be reconsidered. There are many evacuees who have decided to move to other areas but still wish to maintain their hometown ties. These people say they want to return home someday or to get involved in rebuilding their communities in some way.

Scholars have offered ideas to respect their wishes. One would allow them to have a dual certificate of residence for both their previous and current addresses. Another would permit them to become involved in the efforts to rebuild their hometowns while living in other areas.

These ideas can be useful not just for the reconstruction of disaster-stricken areas but also for the revitalization of depopulated rural areas around the nation.

Reviving communities that have been ravaged by the nuclear disaster will inevitably be an unprecedented and long-term process, which requires flexible thinking.

TEPCO Urged to Cut Radioactive Water inside Fukushima N-Plant

feb 2016.jpg

 

 

Tokyo, July 19 (Jiji Press)–Japan’s Nuclear Regulation Authority on Tuesday instructed Tokyo Electric Power Company Holdings Inc.  to reduce the amount of highly radioactive water inside reactor buildings at its disaster-crippled Fukushima No. 1 nuclear power plant.


The nuclear watchdog also demanded TEPCO lower the water’s radiation levels and consider substantially boosting the number of water storage tanks at the plant in order to lower the risk of the contaminated water leaking out.


Currently, there are tanks only enough to store contaminated water being generated every day mainly due to inflows of groundwater.


Meanwhile, the highly radioactive water inside the No. 1 to No. 4 reactor buildings totaled some 61,600 tons as of Thursday. A lot of tanks would need to be built in order to remove the contaminated water from the buildings.


The highly radioactive water may leak out if tsunami hits the plant again, Toyoshi Fuketa, acting head of the NRA, said, demanding cuts in the amount of the water.

Ex-NRA bigwig demands recalculation of Oi nuclear plant quake estimate

fd20120422pba.jpg

A former deputy chairman of the Nuclear Regulation Authority (NRA) sent the organization a letter of protest on July 14 demanding that an earthquake estimate for Kansai Electric Power Co. (KEPCO)’s Oi Nuclear Power Plant be recalculated, on the grounds that the official NRA estimate is well below that of KEPCO.

The former deputy chairman, Kunihiko Shimazaki, is a professor emeritus of seismology at the University of Tokyo. He had criticized the NRA’s estimate of the largest possible earthquake at the Oi plant in Fukui Prefecture as possibly being too low, and the NRA recalculated the estimate in a different manner but still deemed the projected earthquake as not posing a problem to the plant’s safety. In his letter of protest he wrote that he “could not accept the conclusion” of the NRA, and he called for another recalculation. He said he would hold a press conference on July 15 about the issue.

The NRA’s recalculated estimate was 644 gals, “gal” being a unit of acceleration. The estimate was below a KEPCO estimate of 856 gals. Shimazaki, in response to the figures, argues that the NRA’s calculation method is different from KEPCO’s and so produced a smaller number, and notes that the utility finalizes its estimate with additional calculation under stricter conditions, but the NRA has not done so. Shimazaki says that if the calculation was carried out in the same way as KEPCO has performed its estimate, the figure would come out to roughly up to 1,550 gals.

On July 13, a representative for the NRA’s secretariat acknowledged in a Mainichi Shimbun interview that the NRA’s calculation method differed from KEPCO’s, saying, “It’s only natural that there is a difference (in the calculation results).” The representative avoided giving a clear answer about whether it was right for the NRA to green light the plant by comparing results calculated in different methods.

Shinji Kinjo, the head of the agency’s public relations department, said, “If there is a request (for a recalculation), we will consider it sincerely.”

No Chernobyl type Sarcophagus for Fukushima Daiichi?

New-safe-confinement-April-2015-IMG_8575.jpg

Chernobyl new safe confinement construction

After news inadvertently leaked via NHK that the decommissioning authority (NDF) for Fukushima Daiichi was considering a Chernobyl type sarcophagus for the plant, there is now an effort by the authority to back it down.

At the same time the government is rushing to reopen as much of the evacuation zone as possible so they can terminate evacuation compensation for the roughly 100,000 evacuees of the disaster.

Minamisoma reopened closed parts of the district this week and there is now consideration for opening highly radioactive zones in Okuma near the plant in a few years.

Mayors for the impacted towns near the plant expressed obvious outrage to the media after hearing the news.

The media reports and public concern are due to it even being on the table and that alone raises some obvious concerns.

NDF calls the media reports that they are considering a sarcophagus to be “untruthful” but go on to admit that it is now among the considered options.

Obviously such a structure would not be a medium term effort unless it involved some significant new design and long term plan.

NDF also tries to frame a sarcophagus as a more “medium term” solution.

They did confirm that this isn’t a done deal, but is an option they are considering.

Following that news Japan’s state minister for industry has ruled out the option of sealing off disabled reactors at the Fukushima Daiichi nuclear plant with a Chernobyl-style sarcophagus.

Takagi said the government’s policy is to stand by the people of Fukushima, and that his ministry has told the decommissioning body to rewrite its technical report.

Responding to Uchibori, Takagi said the government has no intention of using such an option, and that completing the decommissioning process is the top priority.

The body said it remained committed to removing fuel debris from the reactors that suffered meltdowns in the March 2011 accident.

But it presented a technical report that left room for entombing the reactors in a massive metal and concrete structure.

Yosuke Takagi met Fukushima Governor Masao Uchibori in Tokyo on Friday.

Uchibori said he was shocked to hear the word “sarcophagus” and called the option unacceptable.
