[146], An in-house TEPCO report in 2000 recommended safety measures against seawater flooding, based on the potential of a 50-foot tsunami. However, the condenser did not function properly and TEPCO could not confirm whether a valve was opened. The only MOX fuel was currently loaded in the Unit 3 reactor. [212] Iodine-131 has a half-life of 8.02 days, decaying into a stable nuclide. But most of the radioactivity was dumped in the Pacific – only 19 percent of the released material was deposited over land – keeping the exposed population relatively small. [6] On the 15th, there was an explosion in the Reactor 4 building due to a shared vent pipe with Reactor 3. [120] In March 2012, Prime Minister Yoshihiko Noda said that the government shared the blame for the Fukushima disaster, saying that officials had been blinded by a false belief in the country's "technological infallibility", and were taken in by a "safety myth". After the Fukushima Daiichi nuclear disaster radiation leaked from the damaged reactor for weeks and it was documented that radioactive isotopes seeped into the … As workers struggled to supply power to the reactors' coolant systems and restore power to their control rooms, three hydrogen-air chemical explosions occurred, the first in Unit 1 on 12 March, and the last in Unit 4, on 15 March. "[384][385] A New York Times report alleged that the Japanese nuclear regulatory system consistently sided with, and promoted, the nuclear industry based on the concept of amakudari ('descent from heaven'), in which senior regulators accepted high paying jobs at companies they once oversaw. Radioactive releases in Japan could last months, experts say. The reactors had been closely monitored, as cooling processes were not functioning well. Cabbage, rice[172] and beef showed insignificant levels of radioactivity. Significant pollution along the coast near the plant might persist, because of the continuing arrival of radioactive material transported to the sea by surface water crossing contaminated soil.

[108], The Fukushima reactors were not designed for such a large tsunami,[109][110] nor had the reactors been modified when concerns were raised in Japan and by the IAEA. KPMG reports 653 new nuclear facilities planned or proposed for completion by 2030. Japan government has decided to pump radioactive water to Pacific after Tokyo Olympics. [342][343] For example, the baseline lifetime risk of thyroid cancer for females is just three-quarters of one percent and the additional lifetime risk estimated in this assessment for a female infant exposed in the most affected location is one-half of one percent. [256] Caesium-137 and caesium-134 have been noted in Japanese whiting in Tokyo Bay as of 2016. The International Atomic Energy Agency (IAEA) had expressed concern about the ability of Japan's nuclear plants to withstand earthquakes. At a 2008 meeting of the G8's Nuclear Safety and Security Group in Tokyo, an IAEA expert warned that a strong earthquake with a magnitude above 7.0 could pose a "serious problem" for Japan's nuclear power stations. The government also sought to address the lack of education on the effects of radiation and the extent to which the average person was exposed. [31], When the earthquake struck, units 1, 2, and 3 were operating, but units 4, 5, and 6 had been shut down for a scheduled inspection. 112-75 - ENERGY AND WATER DEVELOPMENT APPROPRIATIONS BILL, 2012 | Congress.gov | Library of Congress", "Accident Tolerant Fuels Effort Hits Important Milestone", Culture of complicity tied to stricken nuclear plant, "Japan to fire 3 top nuclear officials – CNN", "3 former TEPCO executives face criminal trial over Fukushima crisis", "Fukushima nuclear disaster: former Tepco executives go on trial", "Court clears three former Tepco executives", "Fukushima nuclear accident 'man-made', not natural disaster", "Japan says Fukushima disaster was 'man-made, "Official website of the Investigation Committee on the Accident at the Fukushima Nuclear Power Stations of Tokyo Electric Power Company", "Japan, TEPCO ignored atomic accident risks due to 'myth of nuclear safety': Report", "Japan Panel Says Plant Operator Falls Short on Nuclear Safety", "Fukushima Investigators Say More Study Needed on What Went Wrong", "New report criticizes TEPCO over Fukushima nuclear crisis", "Government, Tepco again hit for nuke crisis", The Fukushima Nuclear Accident Independent Investigation Commission Report website in English, Investigation Committee on the accidents at the Fukushima Nuclear Power Station of Tokyo Electric Power Company, Lessons Learned From Fukushima Dai-ichi – Report & Movie, International Atomic Energy Agency (IAEA) Fukushima 5 volume technical report 2015, Webcam Fukushima nuclear power plant I, Unit 1 through Unit 4, Inside the slow and dangerous clean up of the Fukushima nuclear crisis, TerraFly Timeline Aerial Imagery of Fukushima Nuclear Reactor after 2011 Tsunami and Earthquake, Analysis by IRSN of the Fukushima Daiichi accident, Kumamoto, Murata & Nakate: "Fukushima Evacuees Face New Hardship Six Years On", Video from the Unit 2 containment below the reactor in February 2019, Ah humanity!- a film essay by Lucien Castaign-Taylor, Ernst Karel and Véréna Paravel, "Statue of child clad in protective suit met with criticism in disaster-hit Fukushima", "Inside Fukushima Daiichi~This is a virtual tour of the decommissioning site.~"(in English), Fukushima Revitalization Station (Fukushima Prefectural Government) in English, "Reassessment of Fukushima Nuclear Accident and Outline of Nuclear Safety Reform Plan(Interim Report)", Nuclear power in Japan, section Seismicity, ASEAN Agreement on Transboundary Haze Pollution, https://en.wikipedia.org/w/index.php?title=Fukushima_Daiichi_nuclear_disaster&oldid=1002433128, Pages with non-numeric formatnum arguments, Articles with dead external links from June 2016, Articles with dead external links from September 2012, Articles with dead external links from October 2017, Articles with permanently dead external links, Articles with dead external links from February 2018, Articles with dead external links from March 2018, Articles with Dutch-language sources (nl), Articles with dead external links from May 2014, Articles with failed verification from February 2016, Wikipedia indefinitely move-protected pages, Articles that may be too long from September 2018, Articles containing Japanese-language text, Wikipedia articles in need of updating from February 2017, All Wikipedia articles in need of updating, Wikipedia articles needing factual verification from July 2013, Articles with unsourced statements from October 2020, Articles containing potentially dated statements from July 2011, All articles containing potentially dated statements, Articles with unsourced statements from December 2020, Articles with unsourced statements from May 2019, Articles containing potentially dated statements from September 2011, Articles with unsourced statements from December 2013, Articles with unsourced statements from May 2020, Articles with disputed statements from June 2015, Articles with unsourced statements from July 2013, Articles with unsourced statements from June 2015, Creative Commons Attribution-ShareAlike License. However, it had incorporated design changes that improved its resistance to flooding, reducing flood damage. [198], In February 2014, NHK reported that TEPCO was reviewing its radioactivity data, after finding much higher levels of radioactivity than was reported earlier. This was approximately one four-millionth that of March. J Jpn Soc Disaster Nurs. For Unit 2 and Unit 3 it was estimated that the "fuel is cooled sufficiently". In 2018, the Japanese government reported that one worker has since died from lung cancer as a result of exposure from the event. [240][241] The health risks were calculated by applying conservative assumptions, including the conservative linear no-threshold model of radiation exposure, a model that assumes even the smallest amount of radiation exposure will cause a negative health effect. We must not only track those problems, but also treat them. The pair say that there could be thousands of worldwide deaths attributed to the Fukushima Daiichi nuclear power plant disaster — the worst nuclear disaster since Chernobyl. Effects are quantified with a 3-D global atmospheric model driven by emission estimates and … All six units were given access to these generators, but the switching stations that sent power from these backup generators to the reactors' cooling systems for Units 1 through 5 were still in the poorly protected turbine buildings. Fukushima nuclear disaster preventable, court rules, with more damages claims likely Government and company Tepco ordered to pay some damages for 2011 event, but ruling could spur further claims Plaintiffs and their supporters march in Japan ahead of the court ruling in Sendai on the tsunami-crippled Fukushima Daiichi nuclear power plant disaster on Wednesday. [370] In France, President Hollande announced the intention of the government to reduce nuclear usage by one third. [21], In 2018, tours to visit the Fukushima disaster area began. [241][244] It predicted that populations in the most contaminated areas faced a 70% higher relative risk of developing thyroid cancer for females exposed as infants, and a 7% higher relative risk of leukemia in males exposed as infants and a 6% higher relative risk of breast cancer in females exposed as infants. [332][333], For generation II reactors located in flood or tsunami prone areas, a 3+ day supply of back-up batteries has become an informal industry standard. [56] On 16 March 2011, TEPCO estimated that 70% of the fuel in Unit 1 had melted and 33% in Unit 2, and that Unit 3's core might also be damaged. [Some] people have gotten used to being there and some of the places have developed strong tight communities… and now [they] are starting to be torn apart because little by little people are leaving," Jousan said, adding that moving into new housing with new neighbors and new environment can also be a change.“Some of the communities that were in the initial 20km exclusion zone have been opened up for people to live [there] again. [281], Summarizing all responses to questions related to evacuees' current family status, one-third of all surveyed families live apart from their children, while 50.1% live away from other family members (including elderly parents) with whom they lived before the disaster. Fukushima: 16 more cases of child thyroid cancer linked to nuclear disaster Japan: Toshiba robot to help clean up radiation-filled Fukushima nuclear power plant … This resulted in much more decay heat accumulating, as for about 1 day there was no water injection for Unit 1, while Unit 2 and Unit 3 had only a quarter of a day without water injection. The damaged No. The Fukushima nuclear disaster occurred at the Fukushima Daiichi power plant while the Chernobyl nuclear disaster occurred at the Chernobyl Nuclear Power Plant. Yet, as far as we know, no one has yet received a lethal dose of radiation. Mortality among the institutionalized elderly rates after the NPP accident were exceptionally high during the first 3 months, and persisted at a lower level for 9 months, in comparison with similar periods before the accident. [287] After decades of exponential decline in ocean cesium from weapons testing fallout, radioactive isotopes of cesium in the Sea of Japan increased after the accident from 1.5 mBq/L to about 2.5 mBq/L and are still rising as of 2018, while those just off the eastern coast of Japan are declining. [300] Converting to a nuclear-free gas and oil energy economy would cost tens of billions of dollars in annual fees. [161], On 12 March, radioactive releases first reached a CTBTO monitoring station in Takasaki, Japan, around 200 km (120 mi) away. "[272], A 2019 investigation by Yamamoto et al.
