Kyodo, Jul 22, 2017 (emphasis added): In big step forward, Tepco finds melted fuel at bottom of reactor 3 in Fukushima… The debris was clearly identifiable to at least one nuclear expert. “The images that appear to be melted fuel debris match those found in the (1986) Chernobyl crisis,” said Tadashi Narabayashi, a specially appointed professor of nuclear engineering working at Hokkaido University. “It’s definitely fuel debris… It’s an epoch-making event.”

New York Daily News, Jul 22, 2017: Underwater robot captures images of melted fuel at wrecked Fukushima nuclear plant — An underwater robot captured photos of 3-foot thick lumps of melted nuclear fuel covering the floor

Sky News, Jul 24, 2017: Melted nuclear fuel spotted in Fukushima reactor — The radioactive material has been spotted and pictured by a submersible robot…

CNN, Jul 24, 2017: [The robot] has revealed appears to be stalactites of melted nuclear fuel, [Tepco] said… the robot sent back 16 hours worth of images of massive, lava-like fuel deposits

AP, Jul 23, 2017: [Images] showed massive deposits believed to be melted nuclear fuel covering the floor

Asahi Shimbun, Jul 23, 2017: Melted nuke fuel images show struggle facing Fukushima plant — Images captured on July 22 of solidified nuclear fuel debris at the bottom of a containment vessel of the crippled Fukushima No. 1 nuclear power plant show the enormity of decommissioning of the facility… [TEPCO] also discovered that the nuclear fuel debris has spread throughout the containment vessel.

AP, Jul 22, 2017: [TEPCO] said the robot found large amounts of lava-like debris apparently containing fuel that had flowed out of the core… TEPCO spokesman Takahiro Kimoto said it was the first time a robot camera has captured what is believed to be the melted fuel. “That debris has apparently fallen from somewhere higher above. We believe it is highly likely to be melted fuel or something mixed with it,” Kimoto said…

Kyodo, Jul 23, 2017: The robot was sent closer to the bottom of the reactor on Saturday and found possible fuel debris scattered in a wide area.

Japan Times, Jul 21, 2017: Fukushima robot finds potential fuel debris hanging like icicles in reactor 3… The objects spotted this time look like icicles… Tepco is pinning its efforts on technology not yet invented to get the melted fuel out of the reactors.

Reuters, Jul 21, 2017: Tepco detected black-colored material that dangled like icicles that could be nuclear debris near the bottom of the reactor’s pressure vessel that contained the fuel rods, the report said, citing unnamed sources.

Bloomberg, Jul 21, 2017: New images show what is likely to be melted nuclear fuel hanging from inside one of Japan’s wrecked Fukushima reactors… [Tepco] released images on Friday showing a hardened black, grey and orange substance

Financial Times, Jul 24, 2017: [Kimoto] was reluctant to speculate on the nature of seemingly corroded orange patches in the images.

NHK, Jul 23, 2017: [TEPCO] says Saturday’s probe found lumps that are highly likely to be fuel debris piling up at the bottom of the containment vessel… The deposits are estimated to be one to two meters thick. Images released on Saturday show black, rock-like lumps and what appear to be pebbles and sand accumulating at the bottom.

ENENews: “Nuclear Engineer: My biggest concern is Fukushima plant will collapse”



Nuclear Engineer: My biggest concern is Fukushima plant will collapse… Concrete under reactors is being “eaten away”… “There’s ongoing chemical attacks” — Containment structures are tilting, in jeopardy of falling over (AUDIO)

KGO 810 AM, Feb 9, 2017 (at 9:15 in):
Pat Thurston, host (emphasis added): “There’s a story that’s going around the internet, Snopes says there’s nothing to verify that this is true — I guess Tepco is denying it — but there’s a story going around that the containment structure is in jeopardy — its tilting — it’s in jeopardy of falling over, so we’ll talk about that too — if that is even a possibility. Were that to happen, what would that mean?… First, to the issue of the potential for a collapse of the building — for the building to topple over — for it to somehow to collapse. Is that a thing? Can that happen?”

Arnie Gundersen, nuclear engineer: “Yeah, it can happen — and that’s my biggest concern. Tepco is building a wall along the ocean… it’s trapping all this groundwater onsite, and essentially making the ground mushy… There’s already significant damage [to the reactor buildings] — the entire coast of Japan dropped three feet during that earthquake and never rebounded… But the Fukushima site didn’t fall straight, it fell at an angle, it’s about a two inch incline across the site now. So the buildings are in mushy ground and they’re not quite straight. The other part is that there’s a toxic brew of radioactive chemicals inside there, but there’s also just chemicals – they’re eating away at the concrete and they’re eating away at the steel. It’s a nasty chemical broth inside these plants. My fear is that if there’s a Richter 7 quake, not the Richter 9 that happened 6 years ago, if there’s a Richter 7 quake on that site it could breach those containments… The horse is out of the barn at that point… (discussion continues at 32:00 in) On toppling over… probably half the concrete inside the containment that was originally there has been eaten away by the hot radioactive fuel — and there’s ongoing chemical attacks — so I really think the concrete under the containment is pretty darn punky [“resembling punk in being soft or rotted”] right now, and is getting punkier as time goes on.”

Kyodo News, Mar 1, 2017 (emphasis added): A former worker at the site of the 2011 Fukushima nuclear disaster filed a lawsuit Tuesday with the Sapporo District Court seeking labor compensation from the state for his subsequent development of three types of cancer… The man was diagnosed with bladder, stomach and colon cancers between June 2012 and May 2013 after taking part in work to clear debris with heavy machinery at the Fukushima Daiichi nuclear complex… and was exposed to 56.41 millisieverts of radiation in total, according to his written complaint. His application for labor compensation filed at a labor standards supervision office in Fukushima Prefecture was rejected in August 2013. He repeatedly filed requests for re-examination of his application but they were also rejected… But his legal team said, “It’s rare for a person to develop three types of cancer at almost the same time“…

Al Jazeera, Aug 29, 2016: Fukushima’s surfers riding on radioactive waves… An employee of the nuclear plant said that he would never swim here as the water is too contaminated. Five of his friends who work at the plant now have brain damage.



Phoenix New Times, Oct 27, 2016: On my last day in Japan, I met with disaster medicine expert Dr. Atsushi Kumagai in a small conference room in the Fukushima University Hospital, about 52 miles from the Fukushima-Daiichi power plant… Two days after the accident at Fukushima, he, along with two nurses, a radiation technician, and a radiation biologist boarded an army helicopter and flew to Fukushima University Hospital… they managed to set up a temporary and secluded hospital-within-a-hospital at FMU. No one there knew how to handle radiation exposure, which meant that Kumagai and his staff had to train the FMU employees and treat sick people at the same time. For days, the staff worked long hours, taking a few hours at night to sleep on the floor in an empty part of the building. “Every night, we had deep discussions about how to think about this all. We talked about our feelings and anxieties, about the meaning of life, and ‘can we survive?’ “We had such deep conversations, and people cried,” Kumagai says, placing his hands over his heart. “Before the accident, frankly speaking, nobody was concerned about nuclear power… It is a big problem that nobody cared… No one really understood the risk or how to measure or think about the risk,” he says.

Gun control heartburn: Radioactive boars are amok in Fukushima


https://nuclear-news.net/2017/01/04/gun-control-heartburn-radioactive-boars-are-amok-in-fukushima/

Gun.control.heartburn.Radioactive.boars_.are_.amok_.in_.Fukushima-1.jpg

 

The “most adaptable animals that you’ll ever find” are running rampant across parts of rural Japan in the wake of the 2011 nuclear catastrophe and strict gun laws aren’t helping.

The Fukushima Daiichi nuclear disaster, in which a boiling water reactor nuclear power plant largely went Chernobyl after a tsunami knocked it offline has left Japan with a host of problems to include radiation-induced health impacts, some 200,000 displaced locals and possible exposure of groundwater to melted down nuclear fuel for decades to come.

Oh yeah, and the wild hogs.

According to an article in The Washington Post last April, the boar population, lacking natural predators is booming. Worse, thousands of the animals roam an area where highly radioactive caesium-137, which has a half-life of 30 years, has been confirmed.

Most agree that the best way to eradicate the rapid population of would-be Orcs is through hunting, but in gun control-friendly Japan, that is easier said than done.

“Something that complicates wild boar management in Japan is the exceptionally restrictive ownership, use, and access to firearms,” says Dr. Mark Smith, a forestry and wildlife professor at Auburn University, told Outside online. “This includes not only the general populace, but also with researchers, wildlife biologists, and natural resource managers.”

According to the Australian-based Small Arms Survey, the rate of private gun ownership in Japan is 0.6 per 100 people with only 77 handguns in circulation and just 0.8 percent of Japanese households containing one or more legal guns, most often shotguns.

Smith went to Japan to study the problem in 2013.

“Although [recreational] hunting does occur in Japan, it is very limited,” says Smith, “and hunter numbers are declining by the year, so there are fewer and fewer hunters out there harvesting wild boar.”

Plus there is the problem with the meat. In short, there is no good way to make caesium-137 infused pork a balanced part of your complete meal without the diner glowing in the dark, no matter how much BBQ sauce you use.

In Japan, they have to incinerate the carcasses (at 1,771 degrees Fahrenheit) then obliterate the fragments left over with hammers and box them up. Carefully.

Furthermore, the animals are very smart.

“They are the most adaptable animals that you’ll ever find: we call them the ‘opportunistic omnivore,’” says Smith.

Highly radioactive ‘glass’ rained on Tokyo — Fukushima nuclear fuel with 500 Trillion Bq/kg found — “Significant consequences for human health” — Scientists: This changes understanding of disaster… Extreme importance… Our ideas of health implications should change… Do not discuss on social media

Public Release from Goldschmidt Conference, Jun 26, 2016 (emphasis added): New research shows that most of the radioactive fallout which landed on downtown Tokyo a few days after the Fukushima accident was concentrated and deposited in non-soluble glass microparticles, as a type of ‘glassy soot’. This meant that most of the radioactive material was not dissolved in rain and running water… The particles also concentrated the radioactive caesium (Cs), meaning that in some cases dose effects of the fallout are still unclear… Japanese geochemists… analysed samples collected from within an area up to 230 km from the FDNPP… [I]t had been anticipated that most of the radioactive fallout would have been flushed from the environment by rainwater. However… most of the radioactive caesium in fact fell to the ground enclosed in glassy microparticles… [T]hese particles… formed during the molten core-concrete interaction inside the primary containment vessel in the Fukushima reactor units 1 and/or 3. Because of the high Cs content in the microparticles, the radioactivity per unit mass was as high as ~4.4×10^11 Bq/g [440,000,000,000,000 Bq/kg]… Analysis from several air filters collected in Tokyo on 15 March 2011 showed that 89% of the total radioactivity was present as a result of these caesium-rich microparticles, rather than the soluble Cs, as had originally been supposed.

Discovery (Seeker), Jun 27, 2016: Fukushima Accident Rained Glass Particles on Tokyo… Most of the radioactive fallout that descended upon downtown Tokyo in the days after the March 2011 accident [was] glass microparticles — essentially, glass-filled soot. As a result, the fallout, which contained concentrated radioactive cesium, wasn’t dissolved by rainfall, and probably lingered in the environment… Japanese scientists thought that most of it would be washed away by rainwater. Instead, analysis… revealed that most of the radioactive cesium in fact fell to the ground enclosed in glassy microparticles.

ANI, Jun 28, 2016: Research indicates Fukushima radioactive fallout may be worse than expected… Most of the radioactive fallout, which landed on downtown Tokyo a few days after the Fukushima accident, was concentrated and deposited in non-soluble glass microparticles, as a type of ‘glassy soot’…

Inverse, Jun 26, 2016: Radioactive “Glassy Soot” Fell Over Tokyo After the Fukushima Meltdown… The findings… show that the radioactive fallout… has been poorly understood. Previously, it was assumed that most of the radiation that fell dissolved in rain. This would mean that it would wash out of the soil and through the environment… These tiny glass particles entered the air and fell as soot on the surrounding region. Because the radioactive molecules are contained in an insoluble medium, they will not wash out of the soil with rainwater to the same extent… Beyond the consequences for the environment, there are significant consequences for human health. Breathing caesium encased in glass particles may have a very different impact from exposure to it as radioactive rain…

Scientists from Fukushima Univ., Japan Atomic Energy Agency, Stanford Univ., etc, June 2016: Cesium-rich micro-particles unveil the explosive events in the Fukushima Daiichi Nuclear Power Plant — Cesium-rich micro-particles (CsMPs) retain novel information on the molten core-concrete interaction… CsMPs specimens were discovered… in atmospheric particulates collected at Suginami, Tokyo… [Note: “The author has requested that this abstract is not discussed on social media.”]

Dr Satoshi Utsunomiya, Kyushu Univ.: “This work changes some of our assumptions about the Fukushima fallout… This may mean that our ideas of the health implications should be modified“.

Prof. Bernd Grambow, Director of SUBATECH laboratory, France: “[The observations] presented here are extremely important. They may change our understanding of the mechanism of long range atmospheric mass transfer of radioactive caesium from the reactor accident at Fukushima to Tokyo, but they may also change the way we assess inhalation doses from the caesium microparticles inhaled by humans. Indeed, biological half- lives of insoluble caesium particles might be much larger than that of soluble caesium“.

NHK, Jun 21, 2016: TEPCO admits meltdown cover-up — The president of Tokyo Electric Power Company has admitted the company concealed the reactor meltdowns at its Fukushima Daiichi nuclear plant… TEPCO President Naomi Hirose said at a news conference on Tuesday that the company’s concealment of the meltdowns at the order of its then-president is a grave issue.

AP, Jun 21, 2016: The utility that ran the Fukushima nuclear plant acknowledged Tuesday its delayed disclosure of the meltdowns at three reactors was tantamount to a cover-up and apologized… “I would say it was a cover-up,” Hirose told a news conference. “It’s extremely regrettable.”… TEPCO has been accused of a series of cover-ups in the disaster…

Asahi Shimbun, Jun 18, 2016: A panel investigating Tokyo Electric Power Co.’s response to the triple meltdown during the 2011 Fukushima nuclear disaster revealed an unpardonable breach of trust by the operator of the stricken Fukushima No. 1 nuclear power plant. But there is still a lot more work to be done by the panel to uncover the full scope of the utility’s apparent meltdown cover-up. Immediately after the catastrophic accident at the Fukushima nuclear plant, then TEPCO President Masataka Shimizu instructed employees not to use the term “meltdown,” leading to a delay in the official announcement, according to a report compiled by the investigation panel commissioned by the company. A reactor meltdown, or the melting of nuclear fuel in the core of a reactor, is about as bad as it gets. The panel’s report suggests that in the middle of this unprecedented nuclear disaster the top official of the plant operator was trying to conceal the severity of what was unfolding from the public…

ABC Australia, May 24, 2016 (emphasis added): [ABC’s Mark Willacy] has been invited on a tour of [Fukushima Daiichi]… What Willacy discovers is truly unsettling… retrieving hundreds of tonnes of melted nuclear fuel turns out to be far greater than previously thought.

ABC Australia transcript excerpts, May 24, 2016:

Willacy: Tonight we go on a journey into the heart of this ongoing crisis… and we reveal the frightening enormity of the clean-up… and how dangerous it still is.
Gregory Jaczko, former Chairman of the US Nuclear Regulatory Commission: This really is unchartered territory. Nobody really knows where the fuel is… There’s no playbook – they’re making this up as they go along.
Willacy: The man in charge of decontaminating and decommissioning the Fukushima plant, Naohiro Masuda. Has anything like this ever been attempted before?
Masuda: There has never been an accident at a nuclear plant like the one at Fukushima where three reactors had meltdowns. We are currently working on a timetable to decommission the reactors over the next 30 to 40 years.
Naoto Kan, Former Prime Minister: I think it will take longer… This is a major accident, which has never happened anywhere in the world… 40 years is an optimistic view.
Willacy: We are heading to the buildings housing the melted reactors… Tepco is worried about possible nuclear terrorism, and won’t allow us to film certain security sites.
Masuda: This is a job we’ve never done and there is no textbook.
Willacy: [At Reactor 3 there was an] explosion right after the nuclear fuel melted… What happened inside [Reactor 2] no-one really knows… [Reactor 1] is where probably the worst meltdown occurred. They don’t know where the nuclear fuel is.
Masuda: We haven’t actually seen where the melted fuel fell, so it’s important to find it as soon as possible.
Willacy: For the first time, Foreign Correspondent can reveal just how vast the amount of melted nuclear fuel is, the three molten blobs that lie somewhere deep within each of these buildings.
Masuda: It’s estimated that 200 tonnes of debris lies within each unit… 600 tonnes of melted debris fuel and a mixture of concrete and other metals are likely to be here.
Willacy: The most daunting task, one the nuclear industry has never faced, is getting the melted fuel out. TEPCO admits the technology it needs hasn’t been invented.
Jaczko: It may be possible that we’re never able to remove the fuel. You may just wind up having to leave it there and somehow entomb it as it is. I mean that’s certainly a possibility. There is no playbook, they’re making this up as they go along.
Kan: If all the reactors had had a meltdown, there was a risk that half or all of Japan could have been destroyed… the accident took us to the brink of destruction.
Jaczko: You have to now accept that in all nuclear power plants… there’s a chance you can have this kind of a very catastrophic accident… that’s the reality of nuclear power.

ABC Australia, May 24, 2016: Fukushima clean-up chief still hunting for 600 tonnes of melted radioactive fuel… [TEPCO] has revealed that 600 tonnes of reactor fuel melted during the disaster, and that the exact location of the highly radioactive blobs remains a mystery… [C]hief of decommissioning at Fukushima, Naohiro Masuda, said the company hoped to… begin removing it from 2021… “But unfortunately, we don’t know exactly where (the fuel) is” [said Masuda]. [Gregory Jaczko, Chairman of the US NRC] at the time of the meltdowns at Fukushima doubts the fuel can be retrieved… “Nobody really knows where the fuel is… It may be possible that we’re never able to remove the fuel. You may just have to wind up leaving it there and somehow entomb it as it is.”… For the first time, TEPCO has revealed just how much of the mostly uranium fuel melted down… [Masuda said] “about 600 tonnes of melted debris fuel and a mixture of concrete and other metals are likely to be there.”

RT, May 24, 2016: 600 tons of melted radioactive Fukushima fuel still not found, clean-up chief reveals… [The fuel] burnt through the respective reactor pressure vessels, concentrating somewhere on the lower levels of the station… fuel from Reactor 1 poured out completely… the exact location of the highly radioactive “runaway” fuel remains mystery for TEPCO. The absolutely uncontrollable fission of the melted nuclear fuel assemblies continue somewhere under the remains of the station… [TEPCO’s] plan for Fukushima nuclear power plant implies a 30-40 year period… Yet experts doubt the present state of technology is sufficient to deal with the unprecedented technical task.
