Inspectors urge Japan to dump water from Fukushima plant into ocean
February 17, 2015
Nearly four years after Japan’s massive March 2011 earthquake and tsunami, the country has made “significant progress” toward stabilizing and decommissioning the ravaged Fukushima Dai-ichi nuclear power plant, international nuclear inspectors said Tuesday.
However, the nearly 160 million gallons of contaminated water stored on-site pose massive logistical challenges, and examiners strongly urged Japan to consider controlled discharges of the liquid into the Pacific Ocean once it is treated.
The situation at the crippled plant remains “very complex” and “the benefits [of discharges] could be very, very huge” said Juan Carlos Lentijo, who led the team of 15 inspectors from the International Atomic Energy Agency on a nine-day mission that follows surveys in April and November 2013.
Japanese officials have been reluctant to take such a step at the plant 160 miles northeast of Tokyo, fearing it might further antagonize local fishermen and other residents affected by the initial accident and its aftermath.
In the past year, Japan has succeeded in removing spent and fresh fuel from one reactor, Unit 4, and reduced the inflow of groundwater into the facility. It has also taken steps to clarify which entities are responsible for particular jobs, the IAEA team noted.
But about 80,000 gallons of groundwater continue to enter the plant per day, and building and maintaining storage tanks is increasingly taxing for the 7,000 workers toiling at the site, Lentijo’s team noted. In January, a laborer in his 50s who was inspecting an empty, 33-foot-tall storage tank fell into the vessel and died.
In wake of that accident, Japan’s nuclear regulator called on plant operator Tokyo Electric Power Co. to move toward discharges of treated water.
About half of the water stored on-site has been treated to remove most radioactive contaminants, the IAEA team noted, though current technology does not allow for the easy removal of tritium, an isotope of hydrogen.
Unlike other contaminants, which are suspended or dissolved in water, tritium actually modifies the water molecules and therefore is difficult to separate out.
Still, tritium is considered one of the least hazardous radioactive materials produced by nuclear power plants, and Lentijo said “controlled discharges are a normal practice in the industry.”
“Most of the nuclear power plants are discharging treated water,” he said at a news conference in Tokyo. “This is accomplished with negligible impact on the environment and the safety of the people.”
Japan’s Ministry of Economy, Trade and Industry has solicited demonstration projects from several companies for technology that might effectively treat the tritiated water. Orange County-based Kurion said it was awarded a $10-million grant in November for a pilot programs of its technology in Japan to see if it would be effective at Fukushima.
Among its other recommendations, the IAEA team encouraged Japan to narrow down the number of options being considered for the overall decommissioning plan and to reinforce “safety leadership and safety culture” systems.
A final report from the IAEA team is expected in late March.

Quake near Magnitude 7 hits off northeast Japan — Country’s strongest since 2013 — Felt along entire Pacific coastline, distance of over 1,000 kilometers — Followed by multiple aftershocks, one centered at Japan Trench — Official: Event related to massive 3/11 quake (VIDEO) http://enenews.com/quake-magnitude-7-hits-northeast-japan-strongest-hit-country-2013-felt-along-entire-pacific-coastline-1000-km-followed-multiple-aftershocks-one-centered-japan-trench-official-event-related?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
The Guardian, Feb 16, 2015: Japanese coastal towns evacuated as earthquake hits Pacific… Evacuations were ordered for towns closest to the coast in Iwate prefecture in Japan early on Tuesday morning after a strong earthquake with a preliminary magnitude of 6.9 was recorded… The Japan Meteorological Agency issued a tsunami warning and Japanese broadcaster NHK warned residents a one metre-high wave was expected to hit the coast of Iwate. The quake was measured at a depth of about six miles and shook much of north-east Japan even being felt in Tokyo, 430 miles away.
NBC News, Feb 16, 2015: Japan’s Meteorological Agency cast the quake as an aftershock of the 9.0 temblor that rocked Japan on March 11, 2011… “Because the 3/11 earthquake had such a strong impact, and because it’s an area where it was affected by the 3/11 Earthquake, we are describing this as an ‘aftershock,’” said agency seismologist, Yasuhiro Yoshida… USGS wasn’t characterizing Tuesday’s quake as an aftershock, considering it a separate event.

Japan’s government wrestles with the unsolved problem of nuclear wastes
Government explores options on how to store nuclear waste in the long term, Japan Times, 18 Feb 15
KYODO The government said Tuesday it will consider pursuing a final storage site for nuclear waste that can be opened in the event that policies change or better techniques become available to deal with it.
Officials aim to include the plan in a revised basic policy on the final disposal of highly radioactive waste. The government is currently considering the vexed question of what to do with waste in the long-term, as some of it may need management for tens of thousands of years.
Prime Minister Shinzo Abe’s administration wants to fire up nuclear reactors again following the hiatus caused by the 2011 Fukushima meltdowns, but public opinion remains opposed.
Critics accuse the government of pushing a return to nuclear without answering the question of where the waste will go.
Also on Tuesday, the Science Council of Japan, a representative organization of various scientists, rapped the government’s stance as “irresponsible,” urging it and power companies to develop concrete measures for handling nuclear waste as a prerequisite for restarting reactors.
To fend off such criticism, the revised policy will also declare that the “current generation” is not only responsible for generating the waste it will also take action on the storage question. However, it falls short of mentioning a time frame for deciding on the final storage……..
As for how Japan would store its waste, a policy adopted in 2008 envisions reprocessing the waste, then vitrifying it and placing it deep underground…….
This implies a possible review of Japan’s long-standing but stalled policy of a nuclear fuel cycle that aims to reprocess all spent fuel and reuse the extracted plutonium and uranium as reactor fuel…….
The process of finding local governments willing to host a final repository started in 2002, but there was overwhelming opposition and little progress was made.
The government now plans to choose candidate sites based on their scientific value, rather than waiting for municipalities to step forward.
The Science Council of Japan also suggested that waste be temporarily kept in above-ground dry storage for 50 years in principle, during which the government should try to build a consensus on the issue. It also called for national discussions on how to curb, or setting limitations, on the amount of nuclear waste to be generated. http://www.japantimes.co.jp/news/2015/02/17/national/science-health/final-nuclear-waste-dump-may-be-reversible/#.VOP4A-aUcnk
Fukushima’s serious radioactive water problems, and fatal fall of worker into tank
………Following the incident, Japan’s Nuclear Regulatory Authority met to discuss options for disposing of the radioactive waste, which continues to pose health threats at the facility. The Wall Street Journal reports that the regulatory body’s chairman isn’t pleased with the way the Tokyo Electric Power Company (TEPCO) has handled the disaster, which continues to wreak havoc……..
But the power operator has yet to take action, which has resulted in massive contamination of local groundwater. Reports indicate that up to 400 tons of highly contaminated water is added to the site every day, an insurmountable level that will only make it that much worse to clean up in the future.
TEPCO’s water purification process can’t remove tritium; operator running out of room for storage tanksTEPCO is currently trying to remove radioactive material from the tainted water before dumping it into the ocean. But the system it currently has in place to do this is unable to remove radioactive tritium, which is why the power operator has begun moving the water into large storage tanks onsite.
There are currently about 1,000-and-counting storage tanks at the facility, but TEPCO is quickly running out of space to add more. Besides this, TEPCO is having to continue working towards removing spent fuel rods and replacing cooling equipment to prevent further problems at the plant, which show no signs of relent.

Radioactive water problem at Fukushima continues to grow
Agency Report— Feb 17, 2015 A team of international experts on Tuesday expressed concern about increasing amounts of radiation-contaminated water at a crippled Japanese nuclear plant.
Juan Lentijo, head of the 15-member International Atomic Energy Agency team, said at the end of its 9-day mission.
Lentijo said over 350 tonnes of toxic water was generated daily in the process of cooling three reactors at the Fukushima plant that suffered meltdowns during the 2011 earthquake and tsunami.
“The situation remains very complex, with the increasing amount of contaminated water posing a short-term challenge at the plant.
“The need to remove highly radioactive spent fuel, including damaged fuel and fuel debris, from the reactors that suffered meltdowns poses a huge long-term challenge,’’ he said.
The team said other challenges include persistent underground water ingress to main buildings, the long-term management of radioactive waste and problems related to the removal of nuclear fuel. “Japan has made significant progress in its efforts to plan and implement the decommissioning of the plant run by Tokyo Electric Power Co.
“The team is expected to issue its final report by the end of March, although the path ahead is long, complex and challenging.
“Japan is progressing step-by-step and plans are taking shape, which is a welcome development,’’ Lentijo said. (dpa/NAN)
Fukushima disater recovery funds to be used for Olympic events?
Tokyo Gov. Masuzoe wants to use disaster recovery funds for Olympic events in Tohoku Mainichi, 18 Feb 15 Tokyo Gov. Yoichi Masuzoe says he will ask the central government to use part of the Tohoku tsunami disaster reconstruction budget to cover the costs of staging some events for the 2020 Tokyo Olympics and Paralympics in areas that were severely affected by the 2011 disaster……..

Fukushima nuclear catastrophe changed the world
Magazine: ‘Fukushima catastrophe changed the world’; Worst nuclear accident in history, like two Chernobyls; ‘Poisoned entire landscapes for centuries’ — Study: Fukushima ‘overwhelms’ the peak radioactivity from nuclear bomb testing in ice core samples; ‘Affected the global environment’http://enenews.com/magazine-fukushima-catastrophe-changed-world-worst-nuclear-accident-history-like-having-chernobyls-poisoned-entire-landscapes-centuries-study-fukushima-overwhelms-peak-radioactivity-atmospheric-bom?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
Spiegel Online International (Der Spiegel, German news magazine), Feb. 5, 2015 (emphasis added): [It’s] the worst accident in the history of civilian atomic power… The Fukushima catastrophe changed the world. Nuclear reactors melted down on live television and twice as much radioactive material was released as during the Chernobyl accident in 1986. The disaster… poisoned entire landscapes for centuries and killed hundreds of thousands of farm animals… Fukushima is more than just a place-name, it is an historical event…
Scientists from the Chinese Academy of Sciences, University of Venice, and Nanjing University, Feb 6, 2015: The β radioactivity of snow-pit samples collected in the spring of 2011 on four Tibetan Plateau glaciers demonstrate a remarkable peak in each snow pit profile, with peaks about ten to tens of times higher than background levels. The timing of these peaks suggests that the high radioactivity resulted from the Fukushima nuclear… The released radioactive nuclear substances not only polluted Japan… but also spread to other areas of the Northern Hemisphere via atmospheric circulation and ocean currents, affecting the hemispheric and even global environment. As an overdose of nuclear radiation may seriously threaten human health and wildlife survival, this nuclear accident has caught the attention of the world. The radioactive fallout [was] detected in the atmosphere, soil, surface water, and pastures in the low-altitude regions of North America… Much of the radioactive material was transported by the westerlies, resulting in the fallout over North America… [T]o reach the Tibetan Plateau, material transported by the westerlies has to first circle much of the globe… In May 2011, snow-pit samples were collected on the Gurenhekou Glacier… Dongkemadi Glacier… Muztag Glacier and Yuzhufeng Glacier… In 2005 and 2007, we drilled ice cores… Tanggula ice core [and] Yuzhufeng ice core… Clearly, the peak β radioactivities in the snow pits… are much higher than that in the corresponding local ice cores, and even overwhelm the peak β radioactivities caused by past atmospheric thermonuclear tests in the early 1960s… The peak β radioactivities… are 11.0 and 92.4 times larger than their local average background levels… attributed to the Fukushima radioactive fallout… The Fukushima nuclear accident… created a radioactive horizon that can be used as independent age markers in snow and ice cores in the Northern Hemisphere… providing a direct record of the impacts of human activities on the Earth’s environment…

Many a slip before there’s any Takahama nuclear restart
Local approval is no given for Takahama nuclear restarts , Japan Times 17 Feb 15 FUKUI – Kansai Electric Power Co. wants to fire up its Takahama nuclear plant as soon as possible, but it has cleared only one hurdle in securing a green light from regulators. The next could be difficult: obtaining the consent of local officials.
Areas within 30 km of the plant must have evacuation plans for all residents. Although the plant is located in Fukui Prefecture, the evacuation zone sweeps into Kyoto and Shiga prefectures, and they fear for a repeat of a crisis like the Fukushima meltdowns.
The Nuclear Regulation Authority declared last week that the No. 3 and No. 4 reactors of the Takahama plant meet safety standards.
But Yutaka Nose, mayor of Takahama, called on the NRA to explain what that green light means. He suggested that it record a video for town residents to watch via a local cable television network.
Nose said he himself will only decide whether to approve the restarts after consulting residents.
Fukui Gov. Issei Nishikawa plans to decide in line with the recommendations of a panel of experts conducting an independent assessment at the prefectural government’s behest. He will also, he said, consider sentiment in the town and the prefectural assembly.
Along with the NRA’s safety certificate, Kansai Electric needs to win approval for the systems and facilities it would deploy in the event of an accident.
Nishikawa said he will take everything into account in deciding what to do.
It is unlikely that there will be much progress before April’s gubernatorial election.
If the Sendai nuclear plant in Kagoshima Prefecture is anything to go by, approval could be months away at least. Approval is still pending for a resumption of life at that plant’s No. 1 and No. 2 reactors, even though the NRA gave a thumbs-up in September……..
Taizo Mikazuki, governor of Shiga Prefecture, part of which also falls within the 30-km radius, maintains that he will not endorse the restart of the reactors unless the Takahama plant introduces an “effective” safety system.
Mikazuki was elected last July on a pledge of seeking to phase out nuclear power.
He has warned that in the event of an accident, the fallout won’t respect prefectural boundaries. He believes reactivating nuclear plants should be a matter for other prefectures, not just the one that hosts the plant……
Nishikawa recognizes that there is concern in the Kyoto and Shiga prefectural governments, and therefore he has called on the central government to explain why the reactors need to be restarted. http://www.japantimes.co.jp/news/2015/02/17/national/local-approval-given-takahama-nuclear-restarts/#.VOPwQOaUcnk
2,837 Iitate villagers petition Nuclear Damage Compensation Dispute Resolution Center (NDCDRC)
Residents of Fukushima’s Iitate Village file petition for nuclear damage compensation to restore home village http://www.cnic.jp/english/newsletter/nit164/nit164articles/03_iitate.html Kaori Yoshioka, CNIC Nearly half of the entire population of Iitate Village, Fukushima Prefecture, filed a petition with the Nuclear Damage Compensation Dispute Resolution Center (NDCDRC) on November 14, 2014, demanding measures to restore the lives of the nuclear disaster victims. The petitioners are 2,837 villagers from 737 households and the petition is addressed to Tokyo Electric Power Company (TEPCO) President and CEO, Naomi Hirose.
Main points of the petition seeking NDCDRC arbitration for an out-of-court settlement
The petitioners call on TEPCO to
- admit legal responsibility for causing serious radioactive contamination in the village and inflicting massive damage on the villagers, and to sincerely apologize to the villagers for this,
- pay 3 million yen to each villager to compensate for mental anguish regarding their health and other psychological stress caused by radiation exposure that could have been prevented,
- raise the amount of compensation for the period of evacuation from 100,000 yen per person per month to 350,000 yen,
- pay 20 million yen to each of the petitioners as compensation for destroying their livelihoods and causing psychological distress,
- pay the maximum amount of compensation (that for the “difficult-to-return zone”) to the residents who need to secure their houses, but without categorizing the locations into “difficult-to-return zone,” “restricted habitation zone,” and “evacuation directive lift preparation zone,” and without forcing them to take complicated procedures for filing applications, and
- pay lawyers’ fees for this class action suit.
Purpose of the class action suit
This class action suit was launched by the Iitate residents for the purpose of extracting an apology from TEPCO for forcing all the villagers to evacuate after the utility’s accident at the Fukushima Daiichi Nuclear Power Station in 2011, to seek just compensation for the damage they have suffered in order to regain their pride as Iitate villagers and to restore their home village.
Exploring molten cores of Fukushima nuclear reactors by means of cosmic ray particles
Cosmic Ray Particles Will Reveal the Molten Hearts of Fukushima Daiichi’s Reactors http://spectrum.ieee.org/tech-talk/energy/nuclear/cosmic-ray-particles-will-reveal-the-molten-hearts-of-fukushima-daiichis-reactors By Eliza Strickland 13 Feb 2015 In the radioactive ruins of the Fukushima Daiichi nuclear power plant, engineers are testing a new sensor technology. The goal is to see through layers of steel and concrete to determine the location of nuclear fuel at the hearts of three melted-down reactors.
The sensor technology makes use of muons, subatomic particles generated when cosmic rays collide with molecules in Earth’s upper atmosphere. About 10,000 muons reach every square meter of our planet each minute, and they whiz through most substances largely unimpeded. However, their progress can be blocked by heavy elements like uranium and plutonium.
Based on this discrepancy, several research teams around the world are developing systems that use muons the same way your dentist uses x-rays. By placing muon detectors near a Fukushima reactor building and determining where the particles’ progress is being blocked, researchers can produce a map of the globs of melted uranium fuel inside the reactor.
There’s a critical need for such maps. The 40-year decommissioning of the Fukushima Daiichi power plant is well underway: Robots are busily surveying and decontaminating the shattered reactor buildings, and workers are removing spent fuel rods from pools. But the hardest step is yet to come. Someday, TEPCO workers will have to remove the melted nuclear fuel that glooped at the bottom of the three reactors’ pressure vessels, leaked through fissures and weak spots, and pooled in unknown nooks and crannies.
Before TEPCO can remove this highly radioactive fuel, the company must first figure out its exact location inside the melted-down reactors. That’s a big challenge, as it will be many years before robots or heavily protected humans are able to remove the tops of the reactor vessels to drop down radiation-shielded cameras. What’s more, those cameras still won’t be able to locate the fuel that seeped out through the bottoms of the presure vessels.
That’s where the muons come in. TEPCO is first testing a system developed by Japan’s High Energy Accelerator Research Organization, putting the device near the heavily damaged Reactor 1. This system uses a “muon permeation” method; essentially just determining where muons are blocked in their progress by uranium. According to an email from TEPCO, this first test is just to serve as a proof of principle, and won’t produce detailed maps of the melted fuel’s location.
Another system is under development by the U.S. company Decision Sciences, using a “muon scattering” method invented at Los Alamos National Lab in the early 2000s. This method places muon detectors on two sides of an object of interest, and tracks the trajectory of muons as they enter and leave the object. Because some muons interact with uranium nuclei and ping away in new directions, mapping this scattering can create a more precise map of a uranium blob’s location and contours. Toshiba, a contractor for TEPCO, has enlisted Decision Sciences to develop its system for Fukushima Daiichi. That device will be tested later this year at Reactor 2.
Mission Impossible at Fukushima as nuclear fuel is melting down daily
Japan Official: Fuel from Fukushima reactors is “melting down daily” — AP: No way of confirming melted fuel is at bottom of containment vessels — Tepco Adviser: “Schedule for decommissioning the plant is pure supposition” — The Economist: This is ‘Mission Impossible’ (VIDEO) http://enenews.com/japan-official-fuel-fukushima-reactors-melting-down-daily-ap-confirming-melted-fuel-bottom-containment-vessels-tepco-adviser-schedule-decommissioning-plant-pure-supposition?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
Associated Press, Feb 6, 2015 (emphasis added): A snake-like robot designed to examine the inside of one of three melted reactors at the Fukushima Dai-ichi nuclear plant is ready to begin its expedition… Using information gathered by the robot [TEPCO] plans to repair the damaged chambers enough so they can be filled with water… It is expected to enter the Unit 1 reactor as early as April… Expectations for the robot probe are high after earlier efforts at assessment produced limited success… After its trip, technicians plan to store the robot in a shielded box because of its extremely high radioactivity, and it will not be reused… Computer simulations indicate that all of the fuel rods in the Unit 1 reactor probably melted and fell to the bottom of the containment chamber, but until now there has been no way of confirming that… Because of the reactor damage, large volumes of cooling water continue to leak from them, causing contamination and hampering the plant’s cleanup process.
Wall St. Journal, Feb 6, 2015: For the first time since the Fukushima Daiichi nuclear disaster in March 2011, engineers working for [TEPCO] could soon get their first view of nuclear fuel and debris around the melted-down reactors. It is widely believed that during the meltdowns of reactors No. 1-3… the overheated nuclear fuel also flowed out into the reactor vessels… Extracting the nuclear fuel and debris is the mostimportant task involved in decommissioning… But nobody knows what state these deadly materials are in–even the radiation around the buildings storing the reactors is far too high for people to withstand… Now it is ready to examine the fuel and debris, perhaps as soon as April, with the help of a new robot…
The Economist, Feb 7, 2015: Mission impossible; An industrial clean-up without precedent – The stricken Fukushima Dai-ichi nuclear plant is the world’s most complex and costly industrial clean-up… TEPCO’s early guess was that decommissioning would take 30-40 years. That is certainly optimistic. Engineers are grappling with problems with little precedent… Last October the utility pushed back the start of this removal work by five years, to 2025. Dale Klein, [Tepco adviser and former NRC chairman] says that the schedule for decommissioning the plant is pure supposition until engineers figure out how to remove all the fuel.
Taro Yamamoto, member of the Diet of Japan — House of Councillors representing Tokyo, published Feb 5, 2015: “In Fukushima, each reactor has about 90 tons [90,000 kg or ~200,000 lbs] of uranium. These are melting down daily.”
Japan unable to stop highly radioactive waste from flowing out of Fukushima reactors

NHK World transcript excerpts, Feb. 9, 2015: Managers of Japan’s damaged nuclear plant are facing another delay in dealing with a major source of contamination. They’re working on blocking the flow of radioactive water from reactor buildings to underground tunnels. TEPCO officials met with members of the Nuclear Regulation Authority [which] approved a plan to delay the project… Workers were supposed to remove the highly radioactive water… and after that they would have filled in the tunnels with cement. However, efforts to block the flow of water failed. Engineers need to fill in some gaps that may be left in the area where the tunnels and reactor buildings meet. The setback will likely affect a second project to build an ice wall around the 4 damaged reactor buildings. Tepco officials say they’re already 2 weeks to a month behind schedule on that work.
NHK, Feb. 9, 2015: The workers poured cement into the tunnels while draining contaminated water. But blocking the water was not successful as it continued to flow through the buildings… They say they do not yet know how the latest delay will affect the whole decommissioning project. They are still studying the next steps they need to take.
Kyodo News, Feb 2, 2015: … the project to build a huge underground ice wall — a key measure to prevent radioactive water from further building up at the site — and other operations will likely be delayed by up to a month, it added…TEPCO initially planned to finish constructing the 1.5-kilometer frozen wall around the buildings housing the Nos. 1 to 4 reactors…by the end of next month.
Al Jazeera, Feb 9, 2015: The UN’s nuclear watchdog* says contaminated water leaking from Japan’s Fukushima nuclear plant is still “a challenging issue”. The IAEA is reviewing work to decommission the plant… Tepco is criticized with its handling of radioactive water leaks into the Pacific Ocean.
* IAEA the “UN’s nuclear watchdog”? CNN, ABC, Harvard researchers, and even the UN itself, say yes. Perhaps they should consult with the head of the IAEA on the matter: “I have tried to address some widespread misconceptions in the media about the IAEA’s role in nuclear safety… we are not a ‘nuclear safety watchdog’.” A Bloomberg report on the IAEA notes, “The agency’s safety division garnered little respect in US diplomatic cables that describedthe department as a marketing channel for countries seeking to sell atomic technology…The IAEA’s own mission [is] to promote atomic power.”

More approvals still needed for restart of two Japanese nuclear reactors
Two more Japan nuclear reactors get safety clearance TOKYO Thu Feb 12, 2015 (Reuters) – Japan’s atomic regulator on Thursday cleared a second set of reactors for restart, another step towards returning the country to nuclear power after the Fukushima disaster of 2011 led to the shutdown of all units.
Two reactors at the Takahama nuclear station operated by Kansai Electric Power, Japan’s most nuclear-reliant utility before Fukushima, passed the basic standards for operation, Nuclear Regulation Authority (NRA) commissioners said at a meeting.
They must still get approval from the NRA on design upgrades and go through operational checks, as well as get the greenlight from local authorities to restart……..
Japan’s public remains opposed to atomic power, but Prime Minister Shinzo Abe’s government has been pushing to restart nuclear reactors that meet strict rules set after the Fukushima disaster. http://in.reuters.com/article/2015/02/12/japan-nuclear-restarts-idINKBN0LG07C20150212
1,000 homes being torn down after decontamination
NHK has learned that at least 1,000 homes in Fukushima Prefecture will be demolished — even after they have been cleaned of radioactive fallout from the 2011 Fukushima Daiichi accident.
Local officials say that’s a waste of time and money. They call on the government to run the decontamination work more efficiently.
NHK polled officials from 9 Fukushima municipalities where demolition is under way. Each municipality remains partly or completely evacuated.
Officials from 3 towns said about 1,080 houses are to be torn down despite being decontaminated as requested by residents. Naraha Town reports the largest number, around 870.
Officials say leaking rain and animal intrusions are damaging the homes while residents remain evacuated. They also say many evacuees have given up on returning and found new homes instead.
The government pays for both decontamination and demolition programs in evacuation areas. The Environment Ministry says decontamination takes about 2 weeks and costs about 8,300 dollars on average.
An official says the ministry tried to speed up decontamination work at local governments’ requests. He says the ministry will now pursue efficiency as well.
