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
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.”

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
Fukushima 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.
Workers 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.

Tepco 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
Thyroid 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
Better 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
In 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.”
“This ruling is significant as the precedent of a case caused by the nuclear power plant accident,” Tsuguo Hirota said. “Today’s verdict will greatly influence future lawsuits.”……..http://www.washingtonpost.com/world/in-a-first-japanese-court-rules-that-nuclear-plant-operator-is-liable-for-suicide/2014/08/26/bc43af62-6c30-4e70-8e22-ffe1895727c1_story.html

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.

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.

Three 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 dunrenard 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.
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.
