Washington Post, Feb 10, 2016 (emphasis added): Five years after nuclear meltdown, no one knows what to do with Fukushima… one huge question remains: What is to be done with all the radioactive material?… Tepco has built a 1,500-yard-long “ice wall” around the four reactor buildings… however, Japan’s nuclear watchdog blocked the plan, saying the risk of leakage was still too high… [M]ost problematically, there’s the nuclear fuel from the plant itself… “The biggest challenge is going to be the removal of the nuclear fuel debris,” [Akira Ono, Tepco’s Fukushima Daiichi superintendent] said. “We don’t even know what state the debris is in at the moment.”… one of the options the government is considering is building a nuclear waste dump under the seabed, about eight miles off the Fukushima coast… Many groups… staunchly oppose the idea of burying the radioactive material at sea in such a seismically active area. “At some point it would leak and affect the environment,” said Hideyuki Ban, co-director of the Citizens’ Nuclear Information Center.

Japan Times, Feb 20, 2016: NRA commissioner suggests plan to remove all fuel debris at Fukushima plant may not be best option — A Nuclear Regulation Authority commissioner has suggested that removing all fuel debris from reactors at the meltdown-hit Fukushima No. 1 nuclear power plant may not be the best option. “I wonder if the situation would be desired that work is still underway to extract fuel debris 70 or 80 years after” the nuclear disaster, NRA Commissioner Toyoshi Fuketa told reporters Friday. “There are a variety of options, including removing as much fuel debris as possible and solidifying the rest,” he added… Fuketa said that unlike the disaster at the Chernobyl nuclear power plant, it is “not realistic” to construct concrete buildings to cover reactors at the Fukushima No. 1 plant because the situation is different. The commissioner also questioned whether construction of an underground ice wall around the reactor buildings to prevent radioactive water buildup will prove effective.

Tracking the Fallout and Fate of Fukushima Iodine-129 in Rain and Groundwater


Matt Herod, Univ, of Ottawa Ph.D Candidate, Dec 21, 2015 (emphasis added): A recently published paper (by myself and colleagues from uOttawa and Environment Canada) investigates… [Iodine-129] which was released by the Fukushima-Daichii [sic] Nuclear Accident… Within 6 days of the FDNA 129I concentrations in Vancouver precipitation increased 5-15 times… sampling of groundwater revealed slight increases in 129I… The results in rain show an increase in 129I concentrations of up to 220 million atoms/L… 129I anomalies [in groundwater wells], which occurred exactly when the recharge age predicted they would, suggests that some of the 129I deposited by Fukushima was reaching the wells… [P]ulses of elevated 129I occurred for another several months. Elevated 129I concentrations were measured in two wells… indicating that 129I from Fukushima can be traced into groundwater… [M]odeling has shown that 129I can be rapidly transported to the water table…

Scientists from Univ. of Ottawa’s Dept. of Earth Science and Environment Canada (Government of Canada), Dec 2015: The atmospheric transport of iodine-129 from Fukushima to British Columbia, Canada and its deposition and transport into groundwater

The Fukushima-Daiichi nuclear accident (FDNA) released iodine-129 (15.7 million year half-life)… The mean pre-accident 129I concentration in rain was [31,000,000 atoms/L]… following the FDNA, 129I values increased to [211,000,000 atoms/L]… [P]ulses of elevated 129I continued for several months…
The 129I in shallow… groundwater showed measurable variability through March 2013 with an average of [3,200,000 atoms/L]… coincident with modeled travel times…
Radionuclides released from the FDNA have been detected across the globe… [R]eleases of 129I and 131I… travel great distances…
The Abbotsford-Sumas Aquifer… spans the Canada–U.S. border between [B.C., Canada and Washington, US] and supplies ∼120,000 people with drinking water…
A pulse of 129I in precipitation with maximum concentrations of [211,000,000 atoms/L] in Vancouver and [221,000,000 atoms/L] at Saturna Island was observed 6 days following the FDNA. A value of [311,000,000 atoms/L] was also measured during the first week of July…
The high 129I concentrations while the FDNA was ongoing are attributed to the rapid trans-Pacific transport of 129I from Fukushima… This response in 129I concentrations shows that radionuclides from Fukushima were transported rapidly from Japan to the west coast of Canada and the US… [Sampling from Washington State], which is a composite of rainfall events spanning 15 March 2011 to 16 April 2011 shows a significantly elevated 129I concentration of [95,000,000 atoms/L]…
There was a spike in 129I concentration observed in the precipitation sample from the period of 1 July 2011 to 8 July 2011 [which] rose to [311,000,000 atoms/L]… a substantially higher concentration than any other sample… As monitoring at Fukushima detected no pulse of 129I in precipitation in July… this spike is likely due to a… nuclear fuel reprocessing facility. Modeling of the air parcel back trajectories… for the sampling period shows air mass trajectories from Hawaii, north Japan, and Russia…
The initial increase in 129I concentration at the water table appeared within ∼95 days, with a maximum concentration of [10,500,000 atoms/L]…
In the model cases, 129I reached the water table very rapidly…
Groundwater 129I concentrations in two nearby wells showed minor anomalies over the sampling period which could be due to rapid infiltration of the FDNA atmospheric 129I signal… [M]odeling shows that it was possible for a component of the 129I deposited by the FDNA to be conducted rapidly from the ground surface to the water table… We conclude that it is possible that a fraction of 129I from the FDNA is transported conservatively in this aquifer via preferential flow paths to the water table…

NHK, Dec 17, 2015 (emphasis added): [TEPCO] says radioactive fallout that polluted the environment in mid-March of 2011 was likely caused by a leak directly from a containment vessel of the facility’s No.3 reactor. Officials… on Thursday reported their latest findings on what happened at the plant… They concluded that radioactive contamination of the environment between the night of March 14th and the 16th was likely caused not by the vent operations but failure of the vessel. They said the vessel likely lost airtightness due to heat from nuclear fuel, leading to the direct release of radioactive substances into the environment.

NHK transcript, Dec 17, 2015: [TEPCO] said the substances in one of the reactors probably leaked directly from the containment vessel… They suspect the heat of fuel caused the containment vessel to lose airtightness.

http://www.tepco.co.jp/en/press/corp-com/release/2015/1264512_6844.html
TEPCO, Dec 17, 2015: A significant release of steam from the night of March 14 to March 16, 2011 is believed to have been responsible for contamination to the surrounding environment of Fukushima Daiichi. The investigation reports that the primary containment vessels in Units 2 and 3 did likely lose leakage resistant properties by March 15 and had been in a condition where radioactive materials could leak directly from them. It is therefore presumed the environmental contamination outside Fukushima Daiichi during that period was caused by steam leakage directly from the primary containment vessels and not from the vent.

TEPCO, Dec 17, 2015: Leakage and release of a large amount of steam from the Unit 3 Reactor Building — The PCVs of Units 2 & 3 lost the airtightness in the end, which is confirmed by the fact that steam escaped from the Reactor Buildings. Analysis of the behavior of the pressure in the PCVs and the situation at the time of the accident has revealed that the environmental contamination from the night of March 14 to March 16 occurred by steam leakage together with radioactive materials directly from the PCVs not from the vent.

UBS Investment Research (via WikiLeaks), Apr 2011: Of particular concern was Unit 3, because, since September 2010, the plant had been fueled with mixed oxide, or MOx… Use of MOx heightened fuel risk — Fukushima Daiichi Unit 3 was fuelled with mixed oxide (MOx), which is about 93% uranium and 7% plutonium. This has caused additional worries for TEPCO and the government, because MOx is more radioactively aggressive. We think national nuclear safety reviews might consider restrictions on its use.

FROM ENENews: “West Coast Scientists: Everything’s dying… Dead, dead, dead, and dead” “Experts investigate what’s killing sea urchins and cucumbers in Pacific Northwest — “Seeing things never previously observed” Like DDuuuhhhh! It Wouldn’t Be Radiation From Fukushima, Now Would It? (sarcasm supplied)

Ya know, these clowns never cease to amaze me.  What the hell do they think is going to happen, with all that radiation pouring into the Pacific, day in and day out, since March 2011 in Fukushima?  Let’s act like a bunch of bumbling idiots, and pretend we don’t know what the hell is causing this mess.  I just posted yesterday, on one of my blogs, that TEPCO has given up, they decided that they cannot do anything about the constant dumping into the ocean.  Why in God’ s name, the countries around the world, have done nothing to assist, I will never know.  So when the Oceans die, humans die, got it?

National Geographic, Nov 17, 2014 (emphasis added): Urchins and cucumbers seemed to have escaped the ill effects of the virus until now. But in recent weeks, reports have started to come in that they too are dying along beaches in the Pacific Northwest, Hewson said… [He and his team are] studying the urchins and sea cucumbers that are already dying to see if the same killer is responsible.
Everythings Dying Urchin Cucumber

Dr. Bill Bushing, kelp forest ecologist, Nov 2, 2014: I’ve mentioned before that [in Southern California] our starfish and sea urchins have been dying… I’ve recently seen sea cucumbers that appear to be diseased as well… I’ve also observed strangely colored sea hares (big shell-less snails) in the park. The red algae they normally eat seems to have died out… Divers also report seeing far fewer of the sea hares this year.

Ronald L. Shimek, PhD, marine biologist, Nov 10, 2014: Jan Kocian, diving photographer extraordinare… has been actively surveying several marine subtidal areas in northern Puget Sound for some time… [During a Sept. 18] dive… on Whidbey Island, Washington… he started seeing things he had never previously observed.… there were many animals lying exposed on the sandy sea floor, looking limp, sick or dead. Red sea cucumbers were flaccid and dead… Aleutian Moon snails were in odd postures… pink/yellow worms [were] another rare or unusual sight…. Nuttall’s cockles were on the sediment surface with their siphons out, instead of being buried… 22nd September, the area containing dying animals was not only still present it was spreading; whatever seemed to be the cause was still doing its dirty work… 25th September [many] red sea cucumbers… were lying fully exposed, and apparently dead… 29th of September… A few living Cucumaria were acting oddly, not quite dead, but just slightly responsive to touch… Numerous green sea urchins were found with their spines in abnormal postures, definitely not looking healthy… The full extent of the dead area, and the reason for the mortality, remain indeterminate.
