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.

Official Report: West Coast hit with 220,000,000 atoms per liter of Iodine-129 in rain after Fukushima — 15 Million year half-life — Detected in aquifer that supplies drinking water to large number of people — “Transported rapidly” to Canada and US — Elevated levels continued for many months

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…

Boone BA 300x179

Bristol Herald Courier, Jan 14, 2015 (emphasis added): Water is still seeping at Boone Dam and the cause has yet to be determined… Boone Dam has two portions, a concrete portion [and] an earthen embankment. “The leak is actually in the embankment, that’s where all the focus is,” Travis Brickey, a spokesman for TVA, said Monday… TVA is currently drilling around the area where the units discharge water… Though there is no clear timeline on how long the investigation will take, Brickey said that it’s safe to say that there will be a project at the dam. But he’s not sure… how long the project will last or how it will impact the reservoir.

WJHL, Jan 12, 2015: TVA… says it plans to make an announcement about… water seeping out of a nearby riverbank near Boone Dam [after] what’s now being

    described as a “prolonged analysis” to find the source of the water moving underground… [TVA spokesman Travis Brickey] confirmed TVA engineers now suspect water is moving through fissures in rock under the earth-filled section of Boone Dam… TVA has lowered Boone Lake [to reduce] pressure on the dam [and] stopped passing water through its power-generating turbines at Boone Dam as a safety precaution… That’s forced TVA to release water [which is] shooting into the air… a highly visible water release that seems to have fired speculation about what’s going on at Boone Dam… TVA is non-committal about its plans to refill the lake in the spring. “It’s too soon to tell,” Brickey said.

    TVA spokesman Travis Brickey, Jan 12, 2015: “We are considering all possibilities and continue to analyze the data… We’ve installed additional monitoring equipment along with an extensive core drilling campaign… We’re aware that there are plenty of rumors… Our engineers are working to develop next steps.”

    More from Brickey: “We’re doing a lot of engineering work and looking at repair options and what that might entail… I assure you there are a lot of people working on this.”

    WCYB, Dec 29. 2014: People who visit Boone Lake won’t be seeing normal water levels any time soon… Brickey says that TVA is reviewing repair options on Boone Dam… But, the longer it takes for TVA to announce the plans, the more concerned many marina owners are becoming.

    Kingsport Times-News, Dec 29, 2014:“It’s all speculation,” Brickey said of rumors that the lake’s drawdown could last two years or longer… TVA’s most recent press [said] “reservoir levels could be lowered further if conditions change… The duration of the drawdown will depend on the results of the ongoing analysis.”
