KING 5 News, May 9, 2017 (emphasis added): Hundreds of workers were told to take cover at the Hanford Nuclear Reservation after a tunnel full of highly contaminated materials collapsed… Officials say a collapsed patch of ground above the tunnel was larger than first believed. The U.S. Department of Energy said the collapse covered about 400 square feet instead of the 16 square feet first reported… A source said “take cover” status was expanded to the entire site at 10:35 a.m… Washington Gov. Jay Inslee said the Department of Energy and The White House reached out to his office after the incident. “This is a serious situation… Our understanding is that the site went into immediate lockdown“…

USA TODAY, May 9, 2017: [A] manager sent a message to all personnel telling them to “secure ventilation in your building” and “refrain from eating or drinking.”… In the past, rail cars full of radioactive waste were driven into the tunnels and buried… Hanford’s emergency operations center was activated… long-time workers think it may be the first time it was opened for a possible radioactive release.

Yakima Herald, May 9, 2017: BREAKING… Several counties adjacent to the Hanford Site — Yakima, Walla Walla, Grant and Adams counties — participated in a mid-morning conference call with the state Emergency Operations Center, Yakima interim EOC director Tony Miller said. “At this time, we’re monitoring the winds“… If there should be a release of contamination that goes beyond the boundaries of the Hanford site, it would mean that produce would not be allowed in or out of the affected area, Miller said. Milk and the dairies in the Valley could be affected as well…

Statesman Journal, May 9, 2017: Oregon activates emergency operation center after tunnel collapses at Hanford… ODOE officials are coordinating with the Oregon Department of Agriculture, Oregon Health Authority and nuclear safety experts at Oregon State University, ODOE spokeswoman Rachel Wray said Tuesday morning. “Hanford is 35 miles away from Oregon,” Wray said. “We are concerned about Oregonians’ health and that concerns the food we eat.”

US Dept. of Energy: An alert was declared at the Hanford Site this morning… Later this morning, the alert was expanded to a Site Area Emergency. A Site Area Emergency is declared when the event is affecting or could potentially affect personnel beyond the facility boundary…

Tri-City Herald, May 9, 2017: Private pilots in the area have been told to avoid flying over Hanford. The Hanford Patrol is working with the Federal Aviation Administration to put a formal air restriction in place until the FAA can confirm there is no danger.

Fox News, May 9, 2017: “We need to understand whether there has been any environmental contamination resulting from the subsidence at these tunnels,” [Sen. Maria Cantwell, D-Wash.] said.

KHQ, May 9, 2017: Hanford tunnel collapse prompts fears of radioactive contamination

Washington Post, May 9, 2017: “It appears that this is a potentially serious event,” [Edwin Lyman, a senior scientist at the Union of Concerned Scientists] said. “Collapse of the earth covering the tunnels could lead to a considerable radiological release.”

Cemetery full of dead babies missing brains next to US nuclear site — Funeral Director: Almost all infants we have died the same way… “that’s pretty much all I see on death certificates” — Few miles from “most contaminated place in hemisphere” — “One of largest documented anencephaly clusters in US history” (VIDEO)

Seattle Times, updated Jan 28, 2016 (emphasis added): How the state is missing chances to find deadly birth defect’s causeat least 40 other mothers have lost babies to [anencephaly, which result in missing large parts of the brain] in Yakima, Benton and Franklin counties since 2010… one of the largest documented clusters of anencephaly in U.S. history… “Something’s going on and someone needs to tell us,” said [mother Sally] Garcia… Dr. Lisa Galbraith was one of the doctors… In Prosser, the obstetrician oversaw care of Garcia’s pregnancy and others affected by the disorder… “I had a total of four or five babies with anencephaly over the course of two years,” recalled Galbraith… the rate of anencephaly was much higher [than US averages]… Washington health officials… have collected no blood samples, performed no genetic tests and conducted no examination of water, soil… and have no plans to do so… In Texas, just three babies with anencephaly sparked enough outrage to overhaul the state’s birth-defects reporting system.

Seattle Times video transcriptCarlen Majnarich, funeral director: “It’s tragic… It just seems like that’s pretty much all I see on the death certificate is the same diagnosis. And nobody seems to know why. We average close to 100 families a year here in Prosser [a few miles from Hanford]. Almost all the infants that we have have died of anencephaly. It’s just what do you say?”… Sally Garcia (mother who lost her baby to anencephaly): “All these on this side [of the cemetery] are all babies… all babies, starting from right there.”

The Legal Examiner, Dec 31, 2015: [T]he strange eruption of anencephaly cases, which occurs in Washington at a rate almost 5 times as high as the national average, has highlighted a number of government policies that may actually conceal these sort of birth defect “clusters,” rather than help investigate them.

KVEW-TV, Mar 4, 2016: As of November 2015 cases of anencephaly have continued to increase with the current rate at 9.5 per 10,000 live births.

Sara Barron, MS, BSN – American Journal of Nursing, Mar 2016: In the spring of 2012 two babies without brains were born within weeks of each other at the rural hospital in Washington State where I was working… I was stunned when the delivering physician said another patient was expecting the same outcome. After speaking with colleagues at neighboring hospitals, I learned that two other babies with anencephaly had recently been born in the area. In over 30 years of nursing, I had seen only two cases of anencephaly prior to these. I called the Washington State Department of Health and reported a birth defect cluster… RISK FACTORS… Radiation exposure. Popular media and blogs have often linked the Washington State NTD cluster to the Hanford Nuclear Reservation in Benton County, Washington. Although leaks from nuclear power plants have been associated with a higher rate of anencephaly and other NTDs, Washington State Department of Health investigators point out that the three counties with the highest prevalence of NTDs were both upwind and upriver of the Hanford site, making the nuclear plant an unlikely cause of the 2012 cluster.

  • KOIN: “The biggest, most toxic nuclear waste site in the Western hemisphere

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.

Al Jazeera, Jan 6, 2016 (emphasis added): In warming ocean, record number of seals and sea lions sicken and starve — Ailing or dead seals and sea lions washed up on California beaches in record numbers in 2015; this year could be worse… They are brought in with all sorts of problems: lockjaw, poisoning, cancer… But most of the record number of seals and sea lions washing up on California’s shores and being brought to a regional rescue center are starving… this slow-motion catastrophe is likely to continue… In 2015, [NOAA] counted more than 4,200 California sea lions, 90 Guadalupe fur seals, and 70 northern fur seals. The [Marine Mammal Center’s] staff began to realize something was different early in the year… the pups brought in for rescue were unlike anything the veterinarians had ever seen… It was the worst year in the center’s 40-year history, staff said… Only half the usual number of sea lion pups were born off the California coast in 2015, [Dr. Shawn Johnson, director of veterinary science at the Marine Mammal Center] said… veterinarians at the Marine Mammal Center are bracing for the worst.

Dr. Shawn Johnson, director of veterinary science at the Marine Mammal Center: “They were basically just skin and bones. Their liver, their pancreas, their intestines were basically shut down. And they were eating themselves from the inside to stay alive by the time we saw them… If it continues, if this is the new normal, the sea lion population and the fur seal population in California are going to have severe drops in their overall population.”

Laguna Beach Independent, Dec 18, 2015: With the lowest body weights ever documented, California sea lion pups are not only starving from lack of food, they’re infested with parasites and immune to antibiotics, said [Keith Matassa] the director of the Pacific Marine Mammal Center… A record number of emaciated and dying sea lion and seal pups is expected along local shores this winter… Last year, 3,500 sea lions and seals were rescued by various California marine rehab facilities. This year, the stranded pinnipeds are expected to hit 4,000… The animals are riddled with intestine-perforating parasites, known as thorny-head hookworms. “We’re seeing such a high level of parasites now, it’s not normal,” said Matassa… Antibiotics for infections are proving ineffective… Conditions have “not gotten much better over the past couple of years,” [Sharon Melin, NOAA wildlife biologist] said… The food web, said Melin, “has been out of whack now for quite some time.”… The fact that northern pup seals are following suit signifies the domino effect of a distressed environment, she said… the California sea lion population tops out at 300,000… she predicts a drastic decline to 100,000 due to low food availability… “There’s so many stressors on the ocean right now,” Matassa said.

Canadian Press, Dec 30, 2015 (emphasis added): A female orca calf has been found dead on the west coast of Vancouver Island. Paul Cottrell of Fisheries and Oceans Canada said a surfer spotted the dead whale washed up on Mussel Beach near Ucluelet on Dec. 23… a necropsy was conducted on Christmas Day. Scientists are still awaiting results of tissue-sample testing and a cause of death is not yet known… “All our populations of killer whales are at risk, so it’s a shame regardless of which population it’s from,” he said. “You hate to lose a calf out of these populations.” Scientists have requested a rush on the tissue testing… He said it’s believed the calf was about two months old… Cottrell noted it was especially unfortunate that the calf was female because of their value in contributing to the population.

Express, Dec 21, 2015 (emphasis added): Russians flee Chernobyl-style plant over fears of radioactive leak — Russians took iodine and caused traffic jams… amid fears officials were covering up a radioactive leak. The panic followed the emergence of pictures showing a cloud of vapour pouring from Leningrad Nuclear Power Plant, some 50 miles from St Petersburg. The authorities insisted that the was no radioactive leakage… but people did not believe the “no danger” claim. Radio Svoboda reported that in the wake of the incident on Friday locals in Sosnovy Bor started withdrawing money from their credit cards. They said locals were in panic mode despite statements from officials that the radiation level was normal… One local said: “Everyone got very worried and rushed to get iodine.”… There were traffic jams as residents left the area and headed for St Petersburg… The plant manager (not pictured) insists there are no reasons for evacuation. [Oleg Bodrov, chairman of Green World ecological group] said: “They know well that the officials’ first task is to say all is normal but not to report about danger, even if there is one. All those who understand a bit about nuclear energy know that it was an attempt to mistake the wish for the reality… this vapour is surely radioactive… Bodrov called for medical checks for staff at the power plant. Interfax reported that a special commission was working at the nuclear station aiming to find out the reasons for the emission.

QHA, Dec 19, 2015: Accident occurred at Leningrad Nuclear Power Plant (PHOTO) — Eyewitnesses of the accident and the inhabitants of the Russia’s northern capital are scared. The second unit was stopped at the station… The accident occurred at the second power unit when a pipe with steam cracked in turbine hall yesterday. The steam filled the room, and leaked beyond the power plant. The employees of the Leningrad Nuclear Power Plant (LNPP) had to go home… According to specialists, the release was radioactive, because the waste steam entered the so-called loop reactor coolant. However, the population was encouraged not to panic.

Baltic Newsletter of the Green World, Dec 20, 2015: An emergency stop of the second power unit of Leningrad Nuclear Power Plant took place… The reason for the stop and cooling of the reactor was a sudden leak of radioactive steam from a faulty pipe in one of the rooms of the turbine shop… During the cooling – down step, the reactor steam was ejected through the pipe into the environment. A south – southeast wind of 5 meters per second (not typical for this area) blew the radioactive steam toward the Gulf of Finland… Thus, the five millionth city of St. Petersburg, located 40 km east of the Leningrad Nuclear Power Plant was fortunate this time. According to some sources , the radiation level rose a few times higher than the background radiation only in the NPP area.

http://www3.nhk.or.jp/nhkworld/english/news/20151217_27.html
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.
