NHK,, Nov. 18, 2013: The operator of the Fukushima Daiichi nuclear power plant has begun removing nuclear fuel from a storage pool at a damaged reactor building. Workers placed a special fuel transport container in the storage pool […] At around 3PM on Monday, the workers started to hoist the unused fuel units into the steel container […] debris in the pool of the Number 4 reactor building could obstruct the work. […] The removal work requires extreme caution, as any damage to the units could release high-level radiation.
WSJ, Nov. 18, 2013: “We plan to begin the removal process from around 3 pm today, and work until around 7 pm,” said Tepco spokesman Tsuyoshi Numajiri. […] The units are kept in a pool of cool water to prevent exposure to air, which can cause the radioactive material to heat up and could trigger a sustained nuclear reaction.
BBC,, Nov. 18, 2013: [It’s a critical issue] whether the casks remain watertight so the rods have no contact with air.
AFP,, Nov. 18, 2013: Each rod contains uranium and a small amount of plutonium. If they are exposed to the air […] they would start to heat up, a process that, left unchecked, could lead to a self-sustaining nuclear reaction – known as “criticality”. […] Sceptics say with so many unknowables in an operation that has never been attempted under these conditions, there is potential for a catastrophe. Government modelling in the immediate aftermath of the Fukushima disaster […] suggested that an uncontrolled nuclear conflagration at Fukushima could start a chain reaction in other nearby nuclear plants. That worst-case scenario said a huge evacuation area could encompass a large part of greater Tokyo […]
AP,, Nov.18, 2013: […] [Experts] raised concern about a major earthquake hitting during the removal work. Japanese nuclear engineers were on Monday preparing to move uranium and plutonium fuel rods at Fukushima […] Experts have warned that slip-ups could quickly cause the situation to deteriorate. […]
Kyodo News, , Nov. 18, 2013: Nuclear Regulation Authority Chairman Shunichi Tanaka has said the work requires “great prudence” because the pools are strewn with small pieces of rubble […] “The fuel has to be handled very carefully. There is a need to make sure that a fuel assembly is not pulled out (from the fuel rack) by force when it gets stuck because of the rubble,” he said.
On the brink of nuclear catastrophe at Fukuhsima
IMPENDING FUKUSHIMA NUCLEAR DISASTER WILL BE ‘WORSE THAN CHERNOBYL’ – WHAT YOU NEED TO KNOW Scriptonite Daily, 13 Nov 13 “…….,the stricken Fukushima Daiichi Power Plant in North East Japan has suffered core meltdowns, leaked thousands of tonnes of radioactive water into the ground water of Japan and the Pacific Ocean, and a series of other calamities. The Tokyo Electric Power Company (TEPCO) responsible for the plant has appeared incompetent, secretive and unfit to manage the most complex clean-up operation in the history of nuclear power. TEPCO are about to engage in the removal of highly radioactive, unstable fuel rods. If they make a mistake, we would witness the worst radiological disaster in history. The advice of Nuclear expert Arnie Gunderson in the case of such a mistake? Evacuate the Northern Hemisphere.
The boiling water nuclear reactors of the Fukushima Daiichi Power Plant were not designed or planned by TEPCO. The world’s third largest corporation, American firm GE, designed the four main reactors, which stand at the Pacific Ocean side of the site. A legal case in the 70’s revealed thatGE knew these reactor designs were flawed and the reactors prone to explode due to insufficiently robust ‘pressure containment systems’ – meaning that in the case of a build-up of gas or other pressure, the containment system was not strong enough to hold in the radioactive contents. GE continued to sell them across the world anyway. Not only this, but in the case of Fukushima, they designed the cooling pumps and reactors far too close to the Ocean, given the likelihood of seismic events, making the probability and impact of unsustainable pressure build-ups all the higher………
The biggest crisis at Fukushima though are the impacts of three meltdowns in reactors 1-3, and the fate of the fuel pools. After prolonged exposure the fuel rods melt, forming a boiling pool of radioactive fuel at the bottom of the vessel containing the reactor. Reactors 1, 3 and 4 are believed to be at this stage. However, it is clear that reactor 2 suffered a breach of containment at its core. In fact, TEPCO still have no idea where the cores of the four reactors are. In the worst case scenario, the cores will continue to melt through all material below them until they reach the groundwater, where heat and steam will build until an explosion occurs, releasing the entire nuclear payload of the four stations into the atmosphere.
Without a steady coolant supply, the reactor cores boiled off the water around them, exposing the fuel rods – leaving them damaged and unstable. In the case of reactor 4, this was of an increased seriousness as the fuel pools were exposed to the elements, 18m in the air on a buckled and tilting structure. Inside this fuel pool is 400 tonnes of highly radioactive spent fuel. The radioactive fuel rods are inserted into assemblies of 60-70 rods each. TEPCO need to remove more than 1,500assemblies from the pool before it collapses. The company have issued placatory statements on the matter, telling the Guardian:
“Removing spent fuel is done at any ordinary nuclear power plant, and the equipment and methods we’ll be using here are not that different.”
This statement is disingenuous in the extreme. Nuclear and fuel rod expert Arnie Gunderson uses an excellent metaphor to explain the issues.
“Now nuclear fuel is like cigarettes in a pack of cigarettes. If the pack is new, you can pull a cigarette out pretty easily. But if the pack is distorted and you pull too hard, you’ll snap the cigarette. Same thing can happen inside this fuel pool.”
Removing the rods from the pool is a delicate task normally assisted by computers according toToshio Kimura, a former TEPCO technician, who worked at Fukushima Daiichi for 11 years.
“Previously it was a computer-controlled process that memorized the exact locations of the rods down to the millimeter and now they don’t have that. It has to be done manually so there is a high risk that they will drop and break one of the fuel rods,” Kimura said.
These spent fuel rods contain Plutonium, the most toxic material on earth – trace amounts of which can kill a human being.
Krypton 85 is also likely to be released into the air – this radiation is absorbed by the lungs, is fat soluble and damages sperm and eggs resulting in genetic diseases and deformities.
According to independent consultants Mycle Schneider and Anthony Froggatt, writing in the recentWorld Nuclear Industry Status Report:
“”Full release from the Unit-4 spent fuel pool, without any containment or control, could cause by far the most serious radiological disaster to date,”, releasing three times the radioactive material of the 1986 Chernobyl disaster, or 14,000 Hiroshimas.”
This piece of work starts this month.
If TEPCO, who have so far proven vastly incompetent, somehow manage to pull off this unprecedented activity without creating a nuclear holocaust, they still have to perform the same effort with reactors 1 and 2, which will be much more complex due to even greater damage to the buildings.https://www.scriptonitedaily.com/2013/11/13/impending-fukushima-nuclear-disaster-will-be-worse-than-chernobyl-what-you-need-to-know/
Radioactive water “gushing” out of holes in Fukushima Nuclear Reactor 1 containment vessel
NHK: Holes near bottom of containment vessel identified for first time at Fukushima plant — “Gushing out” of Reactor No. 1 — Similar damage suspected at Units 2 and 3 (VIDEO) http://enenews.com/nhk-holes-found-near-bottom-of-reactor-no-1-containment-vessel-at-fukushima-plant-leak-is-gushing-out-similar-damage-suspected-at-units-2-and-3-video
NHK WORLD, , Nov. 13, 2013: A robot at the damaged Fukushima Daiichi nuclear plant has for the first time identified exactly where highly radioactive water is leaking from a reactor […] the lower part of the No.1 reactor’s containment vessel. […] A camera on the robot captured images of water leaking from 2 holes in the containment vessel […] TEPCO engineers […] say one of the leaks looks as if tap water is gushing out. Radiation levels in the area were extremely high at 0.9 to 1.8 sieverts an hour. Engineers suspect that damage to containment vessels at the No. 2 and 3 reactors is also causing similar leaks […]
Jiji Press, , Nov. 14, 2013: […] “Part of the containment vessel is damaged, and water leaking from there is likely to be flowing down into the ground via the pipe,” a TEPCO official said. […] Water used to cool molten fuel debris is believed to be leaking from the three reactor containers, with highly radioactive water accumulated in the basements. The newly found incident is the first apparent identification of a containment vessel-basement flow […]

Robot finds leaks in Fukushima nuclear plant’s Reactor 1,
Robot detects locations of radioactive leaks at crippled Fukushima nuclear plant RT.com November 14, 2013 For the first time, a remote-controlled robot has detected the exact spot of radioactive water leaks from the crippled Fukushima nuclear plant’s Reactor 1, local media reported.
The robot was sent close to the lower part of the Reactor 1 containment vessel at the wrecked Fukushima Daiichi on Wednesday. Its camera captured images of radioactive water leaking from two holes of the vessel into the building housing the reactor, NHK television reported. ……… However, TEPCO engineers said that they cannot estimate the amount of water that leaked through the holes, NHK reported. They also admitted that Reactors 2 and 3 of the Fukushima Daiichi have similar problems.
TEPCO is now planning to use robots to locate other leaks which have been causing concern, as it is important not only in solving water contamination problems but also in carrying out decommissioning of the reactors…….http://rt.com/news/fukushima-robot-detect-radiation-729/
Fukushima cleanup costs – $250-$500 billion!
The staggering costs to clean up Fukushima Smart Planet By Tyler Falk | November 12, 2013 More than two years since the worst nuclear disaster since Chernobyl, the Fukushima power plant meltdown is still a major, global environmental problem. And the staggering price tag for cleaning it up continues to rise.
The Japanese government just announced that it’s borrowing about $30 billion more to cover costs related to Fukushima, bringing the total amount the Japanese government has borrowed to clean up the mess to around $80 billion, more than three times the amount BP spent to clean up the massive oil spill in the Gulf of Mexico in 2010. That money will go into cleanup, along with compensation for the people who may never go back to their homes near the contaminated area, and the decommissioning of the nuclear reactors. But it’s not money that the government is on the hook for, Reuters reports:……
it should hardly come as a surprise that the cleanup is proving so costly. Independent estimates put the total economic cost of the disaster at $250-$500 billion. Tepco has said it will need $137 billion to cover costs related to Fukushima. And if Chernobyl is any indication, the costs will likely continue for decades to come. And the real issue might not even be the cleanup costs or health concerns, but the fact that a large, productive area of land (of which Japan doesn’t have much to begin with) is now essentially useless and will be for many years, decades, or possibly centuries to come……. http://www.smartplanet.com/blog/bulletin/the-staggering-costs-to-clean-up-fukushima/33974
Another $5 billion borrowed by Japan for Fukushima nuclear cleanup
Japan readies additional $30 billion for Fukushima clean-up: sources BY YOSHIFUMI TAKEMOTO TOKYO Tue Nov 12, (Reuters) – Japan’s government is finalizing plans to borrow an additional 3 trillion yen ($30 billion) to pay for compensating Fukushima evacuees and cleaning up the area outside the wrecked nuclear plant, said people with knowledge of the situation.
The additional borrowing would mark both a recognition of the project’s mounting costs and the difficulty of hitting initial targets for reducing radiation levels in the towns and villages hardest hit by the fallout from the worst nuclear accident since Chernobyl.
The new government borrowing program would increase the amount earmarked for Fukushima-related expenses to the equivalent of just over $80 billion, according to government officials with knowledge of the developing plan who asked not to be named.
That $80 billion excludes the cost of decommissioning Fukushima’s six reactors, a process expected to take decades.
The new funding, which is being reviewed as part of the regular budget-setting process, would increase the amount earmarked for paying for work crews to decontaminate Fukushima towns and villages by about $500 million, according to the sources.
The rest of the extra funding raised by the government would be used to defray the cost of creating a storage facility for the radioactive waste, including topsoil and leaves collected from the evacuated zone, and would be available to pay compensation to more than 50,000 nuclear evacuees who remain shut out of their homes more than two and a half years after a massive earthquake and tsunami in March 2011 triggered meltdowns and explosions at the Fukushima plant…… http://in.reuters.com/article/2013/11/12/us-japan-fukushima-borrowing-idINBRE9AB0H520131112
Doubts about Fukushima evacuees ever going home
Fukushima residents may never go home, say Japanese officials Admission deals blow to government assurances that radiation near the Daiichi nuclear plant can be brought down to safe levels Justin McCurry in Tokyo theguardian.com, Wednesday 13 November 2013 Japanese officials have admitted for the first time that thousands of people evacuated from areas near the Fukushima Daiichi nuclear powerplant may never be able to return home.
A report by members of the governing Liberal Democratic party [LDP] and its junior coalition partner urges the government to abandon its promise to all 160,000 evacuees that their irradiated homes will be fit to live in again. The plan instead calls for financial support for displaced residents to move to new homes elsewhere, and for more state funding for the storage of huge quantities of radioactive waste being removed from the 12-mile evacuation zone around the plant.
The parties’ admission that some areas closest to the wrecked facility will remain too contaminated for people to make a permanent return is a blow to official assurances that radiation can be brought down to safe levels.
The government has come under pressure to abandon those promises amid evidence that attempts to reduce radiation to its target of 1 millisievert a year are failing. Decontamination is woefully behind schedule in seven of the 11 selected towns and villages, forcing authorities to concede recently that they will not complete the work by the March 2014 deadline…….
“At some point in time, someone will have to say that this region is uninhabitable, but we will make up for it,” the LDP’s secretary general, Shigeru Ishiba, said recently. It now appears that officials will abandon efforts to clean up highly irradiated areas closest to the plant and focus on areas where there is a more realistic chance of success……. The last category includes the small town of Okuma, where evacuated residents told the Guardian over two years ago that they had given up all hope of ever returning…… http://www.theguardian.com/environment/2013/nov/12/fukushima-daiichu-residents-radiation-japan-nuclear-power

The Mainichi, Nov. 11, 2013: NRA chairman blocks interviews with Fukushima residents over exposure doses […] NRA Chairman Shunichi Tanaka intervened to limit such interviews to friendly local government leaders, the Mainichi Shimbun has learned. Tanaka’s action is igniting a chorus of protests from members of the NRA’s expert panel […] The panel under NRA Commissioner Kayoko Nakamura’s leadership started deliberations in September by inviting five outside experts, including those in charge of emergency radiation medicine. […] However, when NRA Chairman Tanaka learned of the proposal in late October he rejected it […] Masafumi Yokemoto, professor of environmental policy at Osaka City University […] criticizes NRA Chairman Tanaka for meddling in the expert panel’s deliberations and blocking interviews with evacuees to draw a foregone conclusion that the repatriation of evacuees is the only viable option. […]
Reuters, , Nov. 11, 2013: […] Some had hoped the decontamination project employing thousands of temporary workers to strip trees, spray roads and remove topsoil would be enough […] 90 percent of the projected reduction in radiation comes from natural decay of radioactive particles over time.[…] “No matter how hard they try to decontaminate, radiation isn’t going down. So even though we have decided to go back, we can’t,” said Keiko Shioi, a 59-year-old housewife from Naraha, near the nuclear plant. […]
NHK WORLD, Nov. 11, 2013: Experts call for change in radiation measuring […] A panel of experts is urging the Japanese government to change the way it measures radiation exposure for evacuees from the Fukushima nuclear accident when they return home. […] To date, officials have estimated exposure based on radiation levels in the environment. But the panel says they should measures exposure by equipping individuals with radiation monitors called dosimeters. Radiation measurements made by dosimeters tend to be one-third to one-seventh of readings estimated through environmental monitoring. […] The panel also calls for assigning local government officials and health nurses as advisors in each community. […]
NHK Newsline, Nov. 11, 2013 (h/t Anonymous tip): […] The proposal comes at a time when the government is aiming to lift the evacuation advisory for areas where annual radiation doses are estimated at 20 millisieverts or lower. […] The new method is expected to help promote returns of evacuees as well as reduce costs for decontaminating areas tainted by radioactive fallout.
NHK Newsline, Nov. 11, 2013 (at 0:45 in): Readings on such devices [personal dosimeters] tend to be one-third to one-seventh lower than estimates based on environmental monitoring. […] Radiation measurements made by dosimeters tend to be one-third to one-seventh of readings estimated through environmental monitoring. […] “Individual monitor readings don’t necessarily reflect different radiation levels in a household.” -Fukushima evacuee

RT,, Nov. 7, 2013 — Kevin Kamps, Beyond Nuclear: Well, that’s a great tragedy that the Japanese government is allowing this [resettling near Fukushima] to happen. To within the closest 12.4 miles of the devastated nuclear power plant obviously the landscape is contaminated, the food supplies are contaminated. As your reporter said, it’s up to individual private citizens to try to figure out how bad the contamination is. The environmental groups are trying to help them. So, it’s beyond tragic, it’s a crime what’s happening at Fukushima Daiichi.
Abby Martin’s ‘Breaking the Set‘ with RT reporter Alexey Yaroshevsky, Nov. 8, 2013 (at 26:30 in): What struck me the most, and I’m saying that as a person who’s been in the Chernobyl exclusion zone […] The cities and towns which are located just 10-15 km from the nuclear power station where obviously radiation levels are still very, very high and even lethal in some cases. So those town have been reopened for settlers, we literally saw people rebuilding their houses in these areas and this is creating a huge concern in Japan […] In some other areas 60-70km from the nuclear power station, the areas which have never been included into an exclusion zone, which have never been under lockdown, raditional levels, the ones we’ve encountered, some hotbeds, hotspots of radiation we encountered have 3 microsieverts per hour. And this is the same level as the ghost town of Pripyat in the exclusion zone in the Ukraine, the level which would not allow humans to live in this area. Watch the report here
Eyes of the world on Fukushima, as critical nuclear fuel rods cleanup to begin
“They have to remove the fuel as early as possible – the risk from major structural failure leading to pool collapse is a greater threat than leaving the fuel in situ.”.
Radiation levels in those reactors are still too high for humans to enter, and attempts to use robots to determine the exact location of the melted fuel have failed. Instead, officials are placing their faith in the law of gravity, assuming only that the highly hazardous material lies somewhere deep inside the reactor basements.
Fukushima nuclear cleanup enters critical phase Tokyo Electric Power to begin removing more than 1,500 fuel assemblies from spent fuel pool in unprecedented operation Justin McCurry in Fukushima The Guardian, Friday 8 November 2013 Gazing down at the glassy surface of the spent fuel pool inside the No 4 reactor building at Fukushima Daiichi, it is easy to underestimate the danger posed by the highly toxic contents of its murky depths.
But this lofty, isolated corner of the wrecked nuclear power plant is now the focus of global attention as Japan enters the most critical stage yet in its attempt to clean up after the worst nuclear accident in the country’s history.
Later this month the plant’s operator, Tokyo Electric Power (Tepco), will begin removing more than 1,500 fuel assemblies from the pool, the first step in a decommissioning process expected to last at least three decades.
On Thursday, the Guardian witnessed Tepco’s preparations for an unprecedented operation that the utility’s critics claim has the potential to end in disaster.
The risk posed to the reactor by earthquakes and other natural catastrophes has made removal of the fuel – 1,331 spent assemblies and 202 fresh ones – a matter of urgency. Continue reading
Soon to begin – the dangerous process of removing nuclear fuel rods from Fukushima Unit no. 4
Unit 4 presented particular dangers because its entire stock of fuel rods was in the pool at the time of the accident.
If the operation goes as planned, attention will then focus on the massive challenges posed by Units 1, 2 and 3.
Tepco will not confirm the precise timing of the fuel rod operation but after so much public outrage at the company’s handling of the crisis so far, scrutiny of this latest episode will be intense.
Fukushima nuclear plant set for risky operation http://www.bbc.co.uk/news/science-environment-24843657 7 Nov 13 David Shukman A task of extraordinary delicacy and danger is about to begin at Japan’s Fukushima nuclear power station.
Engineers are preparing to extract the first of more than 1,000 nuclear fuel rods from one of the wrecked reactor buildings. This is seen as an essential but risky step on the long road towards stabilising the site.
The fuel rods are currently in a precarious state in a storage pool in Unit 4. This building was badly damaged by an explosion in March 2011 following the Great Tohoku earthquake and tsunami. Moving the rods to safety is a high priority but has only become possible after months of repair work and planning.
One senior official told me: “It’s going to be very difficult but it has to happen.” Continue reading

Low morale amongst Fukushima’s cut price nuclear clean-up workers
Fukushima: Japan’s Cut-Price Nuclear Cleanup: Human Error, Plummeting Morale and Worker Exodus 福島は割引清掃 By Global Research News Global Research, November 04, 2013
The Asia-Pacific Journal, Vol. 11, Issue 43, No. 2, October 28, 2013. TEPCO woes continue amid human error, plummeting morale and worker exodus By Justin McCurry and David McNeill reporting from Fukushima
During a visit to Fukushima Daiichi in September, Abe Shinzo told workers: “the future of Japan rests on your shoulders. I am counting on you.”
The prime minister’s exhortation was directed at almost 6,000 technicians and engineers, truck drivers and builders who, almost three years after the plant suffered a triple meltdown, remain on the frontline of the world’s most hazardous industrial cleanup.
Yet as the challenges facing Fukushima Daiichi become clearer with every new radiation leak and mishap, the men responsible for cleaning up the plant are suffering from plummeting morale, health problems and deep anxiety about the future. Even now, at the start of a decommissioning operation that is expected to last four decades, the plant faces a shortage of workers qualified to manage the dangerous work that lies ahead, according to people with firsthand knowledge of the situation inside the facility.

The Japan Times, Nov 4, 2013: Tepco to conduct fuel removal test at reactor 4 […] Tokyo Electric Power Co. will conduct a fuel removal test at the No. 4 reactor building of the stricken Fukushima No. 1 power plant, delaying the start of the actual operation by up to two weeks, sources close to the matter said Monday. […]
The test was requested by the Japan Nuclear Energy Safety Organization. […] It has also urged Tepco to have its work evaluated by a group of Japanese and overseas experts formed by the International Research Institute for Nuclear Decommissioning, a Tokyo-based organization founded by Japanese government agencies, nuclear facility manufacturers and electric power companies.
Kyodo News,, Nov. 4, 2013: TEPCO to conduct test for Fukushima No. 4 unit fuel removal […] The operator of the plant, crippled in the March 2011 quake and tsunami disaster, planned to start removing nuclear fuel from a cooling pool at the reactor building as early as next Friday. The decision comes after a government-affiliated nuclear safety agency called for an initial test operation, including transporting a protective fuel cask from the storage pool to another pool in a different building about 100 meters away for more stable conditions for cooling spent fuel, the sources said. The administrative agency, the Japan Nuclear Energy Safety Organization, has already inspected equipment to be used in the fuel removal work […]

Fukushima Daiichi nuclear power plant will probably need a concrete tomb
Japan Nuclear Engineer: I don’t think they’ll ever get Fukushima’s melted cores; Will probably start covering reactors in concrete — German Expert: May encase areas in sarcophagus http://enenews.com/japan-nuclear-engineer-dont
November 4th, 2013
Helmholtz Special, 2012: Dr Walter Tromm is Spokesperson of the […] Nuclear Energy and Safety at the Karlsruhe Insititue of Technology, collaborates on international expert committees on the safety of nuclear reactors: “Debris and scrap metal are to be removed from the plant bit by bit in order to finally dismantle it and/or encase the areas with the highest degree of radioactivity in a sarcophagus.”
‘Fukushima‘ by Mark Willacy, book published July 1, 2013 (Excerpt): […] there was much -expert scepticism about whether the government’s 40-year road map would be achievable. ‘I also hope decommissioning can be completed in 40 years,’ said [nuclear-reactor engineer] Hiroaki Koide. ‘But I do not think it is possible.’ […] In an interview with me 20 months after the meltdowns, TEPCO also appeared to be backing away from its four-decade decommissioning road map, admitting that the task in front of the company was unprecedented. ‘We hope to accomplish it in 40 years as per our engineering schedule,’ said Junichi Matsumoto. ‘But we will need to develop manipulators and other jigs and containers to put the bits in.’ […] the gravest challenge would be locating and removing the melted cores inside reactors 1, 2 and 3. ‘I don’t think they can pick up the melted nuclear cores,’ said Koide.
‘Instead, they’ll probably start work to cover the reactors in a concrete sarcophagus. It will take them more than ten years to even begin this work. And then it will take decades to finish each sarcophagus.’
