Radioactive pollution from Fukushima is becoming a wider problem

Japan Times: Fukushima plant plagued by problems as radioactive material bleeds into Pacific — Radiation level in groundwater now 25,000 times higher than when year began http://enenews.com/japan-times-fukushima-plant-plagued-problems-radioactive-material-bleeds-pacific-record-radiation-level-groundwater-25000-times-higher-when-year-began?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29

Pacific-Ocean-drain

Japan Times, Sept 19, 2014: Tainted water problems still plague Fukushima, despite some positive signs — More than three years since [3/11] the Fukushima No. 1 power plant is still bleeding tons of toxic radioactive water into the Pacific Ocean… [It’s] developed into a wider problem that is stoking public concern… [Tepco] is still trying to find a way to deal with the plant’s utility trenches, which are filled with highly contaminated water. The trenches, which run beneath the plant, were built to house cables and pipes… installed to bring in seawater for cooling purposes… Leaving the tainted water in the trenches is risky. For instance, if another major quake hits and damages the trenches, the toxic water will escape and contaminate the groundwater. Tepco said the trenches… can’t be drained until the leaks from the buildings are plugged…

Asahi Shimbun, Sept 19, 2014: Local fishermen are crying foul over [TEPCO’s] latest plan to discharge processed contaminated water… into the ocean. TEPCO and the central government held the first explanatory briefing… Their explanation was apparently unconvincing. “I can’t believe anything TEPCO says,” one of the attendees said after the meeting… many members of local fisheries associations opposed the plan on the opening day of the briefing sessions… [Others] expressed concern over the plan’s safety. “If a critical problem should occur, (local fisheries) would be severely damaged,” [fisherman Yoshinori Sato] said. “They wouldn’t be able to recover.” Another member criticized the utility for burdening local fishermen with such proposals, asking, “How many times will we have to make a similar painful decision?”

While Japan’s media outlets are focused on the meetings between government/Tepco and the fishermen over the whether to allow ‘processed’ contaminated water releases, new Tepco data published September 18 reveals strontium-90 concentrations are at record levels in groundwater just 100 feet from the ocean. Gross beta has risen to 720 million becquerels per cubic meter (Bq/m³) — and according to Tepco’s most recent strontium-90 tests released September 10 (4 months after the samples were taken), strontium-90 comprises over 95% of the total gross beta at this location — resulting in a Sr-90 concentration of 695 million Bq/m³. At the start of 2014, 28,000 Bq/m³ of gross beta was detected in groundwater from the same well — now 8 months later, the levels are over 25,000 times greater.

TEPCO Prompt Report of Result of Analysis
, Sept. 10, 2014:

Port of Fukushima Daiichi, around Discharge Channel and Bank Protection — Seawater

This newly published data shows record levels of Strontium-90 have been detected at all 6 seawater monitoring locations in front of the destroyed reactors. At 3 of 6 locations levels are around triple the previous record set last year.

Yet a report released by TEPCO days later on Sept. 12, 2014 claims: “Results indicate efforts to protect water are succeeding… inside the port area, concentrations of radioactivity have been steadily decreasing… Strontium… nearest the reactors… show levels of 70-100 Bq/L … Strontium 90 has been reduced to approximately a third of earlier levels [and] are projected to further reduce… Strontium 90 outflows to one-fortieth of the current estimated amount of outflow.”

According to a TEPCO document from last month: “Groundwater around reactor buildings (Unit 1 to 4) is confirmed to contain radioactive materials which have mixed with rainwater having been contacted with contaminated debris left on the ground surface due to the accident… contaminated water in the buildings theoretically does not mix with the groundwater flowing around the buildings.”

120,000 Fukushima nuclear evacuees still displaced, 3 years after

Fukushima nuclear disaster: three years on 120,000 evacuees remain uprooted

Japan’s 2011 plant meltdown has torn apart close families, leaving elderly relatives isolated and villages uninhabited  in Fukushima The Guardian, Thursday 11 September 2014  More than three years after Japan‘s Fukushima nuclear disaster more than 120,000 people from the region are living in nuclear limbo with once close-knit families forced to live apart.

Japan’s nuclear watchdog on Wednesday gave the green light for two nuclear reactors at Kyushu Electric Power’s Sendai plant in south-west Japan to restart, but communities are anxious over the safety aspects. The nuclear industry in Japan has been mothballed since the meltdown.

At a temporary housing complex in Fukushima prefecture one resident, Iiko Kanno, said she now spends her days reading, growing vegetables and counting the days until she is reunited with her grandchildren. As with many of her neighbours, Kanno’s family has been torn apart by the nuclear meltdown, which happened in March 2011…….

A survey conducted this year by the prefectural government found that almost half of the households forced to evacuate were living apart, while almost 70% had relatives suffering from physical and mental health problems.

  • Of the total, 48.9% of households said family members were living in two or more locations. Of that number, 58.6% said relatives who had once lived together had been scattered across three or more sites.

    In the same survey, 67.5% of households said they had relatives who were showing signs of physical or psychological distress. More than half of those afflicted said they had lost interest in activities they once enjoyed or that they had trouble sleeping.

    Kanno’s plight is typical of many Fukushima families who lived together in large rural homes before the disaster………

  • So far only a few hundred people from two districts on the eastern edge of the evacuation zone have been given permission to return permanently……
  • “The nuclear accident turned everything upside down,” she said. “Even if the evacuation order is lifted, no young people or children will go back. We have asked everyone – the village office, decontamination workers, environment ministry bureaucrats – when it will be safe to return. But no one can give us an answer.” http://www.theguardian.com/world/2014/sep/10/fukushima-nuclear-disaster-japan-three-years-families-uprooted

USA Dept of Energy’s estimate of Fukushima radiation release “Not for Distribution, Internal Use Only

“Not for Distribution, Internal Use Only”: US Energy Dept. estimated Fukushima release up to 10,000 times larger than nuclear regulators predicted — ‘Supercore’ scenario an underestimate? http://enenews.com/us-energy-dept-estimated-fukushima-release-up-to-10000-times-larger-than-nuclear-regulators-predicted-supercore-scenario-an-underestimate?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29

Ocean Plume Modeling for the Fukushima Daiichi Event
 (pdf) — US Dept. of Commerce, NOAA, National Weather Service, Sept. 2013:

Estimates of contamination

  • “Coastal releases ignored. According to TEPCO estimates, coastal releases are 1% of atmospheric… Not important for far-field estimates (i.e., exposure for US territories)”
  • “Scenarios used [are] NRC source scenario [and] DOE Supercore source scenario”
  • Regarding Cs-137 release estimates, “NRC and DOE differ by three orders of magnitude” [i.e. DOE estimate is 1,000 to 9,999 times more than NRC]
  • “Enormous uncertainty in total amount of contamination released at FDNPP”
  • “Differences between NRC &  DOE sources are crippling from a scientific perspective”
  • “DOE much too high at… JAMSTEC observation line 30km offshore [and] overestimates Cs-137 by order of magnitude [predicting a] maxima of around 100 Bq/L for Cs-137… JAMSTEC realistic contamination levels would be factor 10 smaller (10 Bq/L).”

Is DOE’s 100 Bq/L an ‘Overestimate’?

  • The above report by the federal government claims to use ‘realistic’ data from the JAMSTEC line (Japan Agency for Marine-Earth Science and Technology) of 10 Bq/L for Cs-137. However, JAMSTEC measured a maxima of 186 Bq/L for Cs137 at 30km off the Fukushima coast — nearly double the DOE ‘overestimate’.
  • The Science Council of Japan: “Oceanic monitoring… identified that 100 Bq/L or more of 137Cs had been diffused to the north and south.”

DOE’s estimate based on the ‘supercore’ scenario came rather close to predicting actual Cs-137 levels observed in samples from the Pacific Ocean — if anything, it appears to be an underestimate.

The reactor conditions assumed in DOE’s ‘supercore’ scenario have been redacted from FOIA documents. However it’s likely that the ‘supercore’ was among the worst-case scenarios discussed by the US government. As reported by Echo News,  around 5 different worst-cases were in play — “I still won’t let anybody use the word ‘worst case’ in the room here because there’s about five worst cases.” -NRC’s Director of Nuclear Security & Incident Response

Final abandonment of Fukushima communities – as governor agrees to nuclear waste storage

wastes-1flag-japanFukushima governor accepts ‘temporary’ radioactive waste storage http://www.radioaustralia.net.au/international/2014-09-01/fukushima-governor-accepts-temporary-radioactive-waste-storage/1363279  1 September 2014,

The governor of Fukushima has agreed to accept the “temporary” storage of radioactive waste from the 2011 nuclear disaster. Yuhei Sato has been cajoled with the promises of subsidies if he accepts a Japanese government plan to build a depot on land near the battered Fukushima Daiichi plant.

“I have made an agonising decision to accept plans to construct temporary storage facilities in order to achieve recovery in the environment as soon as possible,” Mr Sato told central government ministers in Tokyo. A magnitude 9.0 earthquake and subsequent tsunami in March 2011 prompted the meltdown of the Fukushima nuclear plant on Japan’s northeast coast.

The resulting plumes of radiation contaminated areas far and wide, rendering a swathe of Fukushima uninhabitable and forcing tens of thousands of people from their homes.Tokyo’s solution has been to try to scrub the radiation from the affected areas, often by lifting topsoil in the hope that contamination levels will go down. This has left the problem of what to do with all the waste, with no community in Japan prepared to accept its permanent storage.

The government’s answer has been to seek a temporary fix while it works on getting a long-term plan in place.Mr Sato’s acquiescence came after prime minister Shinzo Abe’s government offered subsidies worth more than 300 billion yen ($2.9 billion), including land rent for the facility location.

Under the plan, the government will build storage units on an area of 16 square kilometres near the power plant.

While observers have long said the area around Fukushima is the only viable option, people already displaced have seen it as unacceptable because it would in effect finalise the abandonment of their communities.

Refueling crane console dropped into Fukushima Daiichi Reactor 3 spent fuel pool

exclamation-Smflag-japanWorkers drop refueling crane console into Fukushima Daiichi Reactor 3 spent fuel pool  Enformable,  29 Aug 2014 The workers were carrying out operations to remove debris with a large remote controlled crane.  At the time of the accident, workers were manipulating the control console for the refueling machine, a piece of equipment that weighs almost a thousand pounds.At the crippled Fukushima Daiichi nuclear power plant, workers accidentally dropped a large piece of debris into the Unit 3 spent fuel pool on Friday, a little after noon.

TEPCO is working to check the 566 spent fuel assemblies in the Unit 3 spent fuel pool to see if any of them have been damaged by the most recent accident.  According to decommissioning plans, the utility is scheduled to start removing spent fuel rods from the Unit 3 spent fuel pool in the first half of 2015 at the earliest.Tokyo Electric, who is in charge of cleanup operations at Fukushima Daiichi, told reporters that they have not detected any change in radiation levels around the spent fuel pool after the accident.

This is not the first time that debris and large objects have been accidentally dropped, pulled, or pushed into the Unit 3 spent fuel pool.  Between 2012 and 2013, TEPCO workers used the remote control cranes to remove debris from atop the Unit 3 reactor building, and multiple instances were recorded where operators moving cranes via remote control knocked debris into the spent fuel pool or dislodged other materials on the roof.

In February 2013, workers accidentally knocked the 1.5 ton fuel handling machine mast into the Unit 3 spent fuel pool, and it was later found to have come to rest on top of the spent fuel racks after it narrowly avoided damaging the liner of the spent fuel pool.

The post Workers drop refueling crane console into Fukushima Daiichi Reactor 3 spent fuel pool appeared first on Enformable.

400-Kg Control Console Fell Into Fukushima Fuel Pool

exclamation-Smflag-japanTepco Says 400-Kg Control Console Fell Into Fukushima Fuel Pool Bloomberg, By Emi Urabe and Peter Langan  Aug 29, 2014 Tokyo Electric Power Co. (9501) said it’s detected no change in radiation levels in the Fukushima Dai-Ichi No. 3 reactor building after a 400 kilogram piece of equipment slipped from a crane and fell back into a pool holding spent uranium fuel rods.

The accident happened at around 12:45 p.m. today as the company was attempting to move what it described as a crane control console, according to a statement on its website.

The console, which is about a meter wide and 1.6 meters high, was blown into the pool on March 14, 2011, when the No. 3 reactor building exploded following an earthquake and tsunami that wrecked the Fukushima plant.

Today, the utility known as Tepco was attempting to move the device as part of its cleanup at the site, said spokesman Hiroshi Itagaki. …….http://www.bloomberg.com/news/2014-08-29/tepco-says-400-kg-control-console-fell-into-fukushima-fuel-pool.html

Fukushima’s young thyroid cancer sufferers – the tip of the coming cancer iceberg?

thyroid-cancer-papillaryThyroid cancer diagnosed in 104 young people in Fukushima, Asahi Shimbun August 24, 2014 By YURI OIWA/ Staff Writer  The number of young people in Fukushima Prefecture who have been diagnosed with definitive or suspected thyroid gland cancer, a disease often caused by radiation exposure, now totals 104, according to prefectural officials.

The 104 are among 300,000 young people who were aged 18 or under at the time of the 2011 Fukushima nuclear disaster and whose results of thyroid gland tests have been made available as of June 30. They were eligible for the tests administered by the prefectural government.

Of these 104, including 68 women, the number of definitive cases is 57, and one has been diagnosed with a benign tumor. The size of the tumors varies from 5 to 41 millimeters and averages 14 mm.

The average age of those diagnosed was 14.8 when the Great East Japan Earthquake and tsunami triggered the meltdowns at the Fukushima No. 1 nuclear power plant in March 2011……..

The figure can be extrapolated for comparison purposes to an average of more than 30 people per population of 100,000 having definitive or suspected thyroid gland cancer.

The figure is much higher than, for example, the development rate of thyroid cancer of 1.7 people per 100,000 among late teens based on the cancer patients’ registration in Miyagi Prefecture…….http://ajw.asahi.com/article/0311disaster/fukushima/AJ201408240011

$105 billion is the estimated cost of Fukushima nuclear clean-up

scrutiny-on-costsflag-japanBetter Market Your Uranium Someplace Else, Japan Appetite No Longer Huge as Before – Former PM Tells Australia Queensland Premier Campbell Newman International Business Times, By Esther Tanquintic-Misa | August 28,

“……….In the research made by Kenichi Oshima, environmental economics professor at Ritsumeikan University, and Masafumi Yokemoto, professor of environment policy at Osaka City University, they said the Fukushima Daiichi nuclear power plant tragedy will cost 11.08 trillion yen ($105 billion). The figure ballooned to include radiation clean-up and compensation to residents.

Specifically, the expenses will include

  • 4.91 trillion yen ($47 billion) for compensation to residents in the affected area of the crippled Fukushima Daiichi nuclear plant
  • 2.48 trillion yen ($23 billion) will be involved in the radiation cleanup of the territories
  • 2.17 trillion yen to scrap the disaster-hit plant
  • 1.06 trillion yen for the temporal storage of radioactive soil

Nevertheless, the researchers noted the amount still exclude costs for the final disposal of radioactive substances, compensation and plant decommissioning.

Oshima and Yokemoto said the cost will be shouldered by the Japanese people through taxes and utility bills.http://au.ibtimes.com/articles/564339/20140828/uranium-japan-appetite-kan-australia-queensland-newman.htm#.VADXudJdUnk

A legal precedent, as TEPCO us ruled liable for a Fukushima suicide

justiceflag-japanIn a first, Japanese court rules that nuclear plant operator is liable for suicide WP, By Anna Fifield and Yuki Oda August 26 at 6:07 AM   TOKYO — A court in Fukushima has ruled that Tokyo Electric Power Co., the Japanese nuclear power plant operator, can be held responsible for the suicide of a woman who became depressed after the 2011 disaster.

The court ordered Tepco to pay $470,000 to Mikio Watanabe and his children after his 58-year-old wife, Hamako, killed herself a few months after the nuclear meltdown in the wake of the earthquake and tsunami forced them out of their home and destroyed their livelihoods.

The ruling was the first time that the struggling utility has been found liable for a suicide resulting from the accident, and it could galvanize others seeking redress from the company…….

The family’s attorney declared the verdict a “complete victory.”

Multiple fuel cores ejected from Fukushima nuclear reactors

Studies show multiple fuel cores ejected from Fukushima reactors – Hot particles of uranium and plutonium fuels detected nearly 300 miles away http://fukushimaemergencywhatcanwedo.blogspot.com.au/2014/08/studies-show-multiple-fuel-cores.html

Marco Kaltofen, Nuclear Science and Engineering , presented at Worcester Polytechnic Institute, March 19, 2014:High Radioactivity Particles in Japanese House Dusts… The Fukushima Dai‐ichi accident released very high activity inhalable dust particles that travelled long distances… Airborne dusts can transport radioactive materials as isolated individual particles containing high concentrations of radioisotopes. Alpha and beta emissions related to fission wastes and dispersed fuel particles are hazardous when inhaled or ingested. Radioactively‐contaminated environmental dusts can accumulate in indoor spaces, potentially causing significant radiation exposures to humans via inhalation, dermal contact, and ingestion… a micron‐scaled particle [had] activity greater than 1.0 PBq kg [1 Quadrillion Bq/kg]. The par6cle was collected from a home in Nagoya, Japan. Nagoya is 460 km from the accident site… It contained both fission products and decay products of 238U… tellurium up to 48.0 %, cesium up to 15.6 %, rubidium up to 1.22 %, polonium up to 1.19 %, dysprosium up to 0.18 %, as well as trace amounts of Sn, lead, nickel, iron, and chromium… 226Ra, 134Cs, and 137Cs, 241Am, and 230Th [were] the most commonly detected gamma photon-emitting isotopes… about 25 % of dusts sampled [were] autoradiographically positive for hot particles… the majority of these hot particles were 10 um [micrometers] or less in size, meaning that they were potentially inhalable… Radioactively‐hot particles on the respirable size range were routinely detected, with one as far as 460 km [285 miles] from the release site.

Kaltofen : Radioisotopes in dusts released by Fukushima Daiichi units [include] Uranium and plutonium fuels and transuranics such as americium and neptunium… individual radioactive particles [in an] Ibaraki dust sample [include] Eu, Y, Zr, Th, Ce, Sr… in 1 to 15 um size range…

Kaltofen : The Japanese samples came from as far north as Sapporo in Hokkaido Prefecture and as far south as Tokyo, a range of 780 km. Fifty nine samples of dust from Japan were analyzed… Radioisotopes specific to the Fukushima Daiichi accidents, including Cs134, Cs137, and Co60 were detected in dust samples taken throughout Northern Japan, including areas more than 200 km outside of the accident exclusion zone. Cs134 was detected at all of the Japanese sites tested… Japanese samples… analyzed in the first month after the accident also contained I131 and Am241… Radioactive dust has become a ubiquitous part of life in northern Japan.

Chris Harris, former licensed Senior Reactor Operator & engineer, Aug 21, 2014 (at 24:00 in): NHK just [broadcasted] that many studies are showing… that multiple cores — parts of it, or some, or even most of it — had been ejected. We thought that too. Once you breach containment, that was one of my big concerns — where did the core go after an explosion like? Whether it be steam or hydrogen explosion or a combination of both… it got ‘sneezed out’ all over the place. It’s totally – it’s a huge mess.

U.S. personnel given strict radiation safety orders in Fukushima area March 16 – 19, 2011

text-radiationUS Official: There were orders to not get within 230 miles of Fukushima Daiichi — Potassium iodide given to all defense personnel and families within 200 miles of plant — Over 1,100 kinds of radioactive material detected http://enenews.com/us-official-there-were-orders-not-to-go-within-230-miles-of-fukushima-daiichi-potassium-iodide-given-to-all-defense-personnel-and-families-within-200-miles-over-1100-kinds-of-radioactive-mater

Assistant Secretary of Defense Jonathan Woodson, June 19, 2014: Between March 16 and 19, 2011, ships supporting OT [Operation Tomodachi] were directed to remain at least 100 nm [nautical miles] from Fukushima Daiichi and greater than 150 nm from Fukushima Daiichi along a 90 degree arc, or wedge, centered on the direction of wind from Fukushima Daiichi. The standoff distance from Fukushima Daiichi was temporarily increased to 200 nm [230 miles] on March 16, 2011, as a precaution following detection of abnormally high radiation levels above the Fukushima Daiichi Unit 3 containment building by the Japanese military. On March 19, 2011, the wedge was reduced to 125 nm…

Joint Effects Coordination Board/Joint Requirement Review Board Review:

  • Mar. 17, 2011 — Personnel entering within the 100 nm radius of Fukushima Daiichi Nuclear Power Plants, KI [potassium iodide] should be administered.
  • Mar. 21, 2011 — Mission: Distribute KI to all DOD personnel and families within 200 miles from the Fukushima power plant.

Defense Threat Reduction Agency (pdf), Sept. 2013: The Defense Threat Reduction Agency’s (DTRA) Hazard Prediction and Assessment Capability (HPAC) model was used to generate the radiation exposure rates and air activity concentrations for at-sea crew. Inputs to the HPAC model included data on the isotopes inside [Fukushima Daiichi's] reactors that had the potential for release to the environment… Although HPAC’s output included over 1,100 isotopes, it was determined that the major contributors to inhalation doses were the following 10 isotopes: I-131, I-132, I-133, Cs-134, Cs-136, Cs-137, Te-129, Te-129m, Te-131m and Te-132.

International companies attempting to remove tritium from toxic water at Fukushima nuclear plant

water-radiationThree firms picked to help tackle toxic water at Fukushima No. 1 http://fukushimaemergencywhatcanwedo.blogspot.com.au/2014/08/three-firms-picked-to-help-tackle-toxic.html  by  Aug 26, 2014  The government picked three overseas companies Tuesday to participate in a subsidized project to determine the best available technology for separating radioactive tritium from the toxic water building up at the Fukushima No. 1 nuclear plant.

Tokyo Electric Power Co. is currently test-running a system it says is capable of removing 62 types of radioactive substances from the contaminated water, but not tritium.
Thus tritium-laced water is expected to accumulate at the plant in the absence of any method to remove the isotope.
The three firms chosen from 29 applicants are U.S. firm Kurion Inc., which offers technologies to treat nuclear and hazardous waste; GE Hitachi Nuclear Energy Canada Inc., a joint venture of Hitachi Ltd. and U.S. firm General Electric Co.; and Federal State Unitary Enterprise RosRAO, a Russian radioactive waste management firm.
The government will provide up to ¥1 billion for each examination of the technologies and running costs, and consider whether any of them can be applied to treat the water at Fukushima No. 1, the industry ministry said.
The three companies are to conclude their experiments by the end of March 2016, a ministry official said.
The official cautioned there is no guarantee that any of the technologies will be put to practical use.
