list of nuclear power plant accidents

Does Nuclear Power Have a Place in a Sustainable Energy Future? Many disasters over the years have kept us debating if it is really worth it. New reactor designs have features of passive nuclear safety, which may help. Loss of backup electrical power led to overheating, meltdowns, and evacuations. Significant release of radioactive material to the environment from explosion of a high activity waste tank. Luckily, mountain ranges have shielded western Japan. Resulted in 1 fatality, In August 1968: Soviet nuclear ballistic missile submarine development program Project 667A. 1974–1976: Columbus radiotherapy accident, 10 fatalities, 88 injuries from cobalt-60 source. Media in category "Nuclear power plant accidents" The following 5 files are in this category, out of 5 total. An accident at the Sosnovy Bor nuclear plant leaked radioactive iodine into the air through a ruptured fuel channel. [148] Cs-137 has a long half-life, meaning it could potentially have long-term harmful effects, but as of now, its levels from 200 km outside of Fukushima show close to pre-accident levels with little spread to North American coasts. Today, the Laka-foundation released a list with reports from almost 1,000 incidents and (near) accidents with nuclear power plants and other nuclear facilities. The passage of the Radiation Exposure Compensation Act of 1990 allowed for a systematic filing of compensation claims in relation to testing as well as those employed at nuclear weapons facilities. 5 October 1982: Lost radiation source, Baku, Azerbaijan, USSR. How often do nuclear power plants go wrong? The Federation of American Scientists have said that if nuclear power use is to expand significantly, nuclear facilities will have to be made extremely safe from attacks that could release radioactivity into the environment. On April 26, 1986, the Chernobyl nuclear power plant in Ukraine (at the time the USSR) suffered a tremendous accident. Serious nuclear power plant accidents include the Fukushima Daiichi nuclear disaster (2011), Chernobyl disaster (1986), Three Mile Island accident (1979), and the SL-1 accident (1961). How did it happen? The explosions and nuclear fuel rods melting at Japan‘s Fukushima nuclear power plant, following the Sendai earthquake and tsunami last week, have caused fears of what will happen next. The accident killed 31 people directly and damaged approximately $7 billion of property. The statistic represents the biggest nuclear accidents worldwide from 1957 to 2011, rated by INES scale. Gallery. Citation: Lancet August 2015; 386(9992):405-500. [119] This then led to the overexposure of at least one patient. We have identified 33 serious incidents and accidents at nuclear power stations since the first recorded one in 1952 at Chalk River in Ontario, Canada. In November 2007, burglars with unknown intentions infiltrated the, This page was last edited on 26 December 2020, at 05:53. On January 21, 1969, it suffered a loss-of-coolant accident, leading to meltdown of one fuel element and radioactive contamination of the cavern, which before was sealed. This leads to on average one serious accident happening every eight years worldwide.[137]. [7], The impact of nuclear accidents has been a topic of debate since the first nuclear reactors were constructed in 1954, and has been a key factor in public concern about nuclear facilities. In the United Kingdom, it was revealed in a court case that in March 2002 a radiotherapy source was transported from Leeds to Sellafield with defective shielding. Nuclear families spend evenings debating nuclear energy. 12-32b Preliminary results of radiation monitoring near uranium mines in Namibia", "Namibian workers in times of uncertainty: The Labour Movement 20 years after independence", "Our Work: Labour Resource and Research Institute", "Uranium mining in Namibia: The mystery behind 'low level radiation, "WIPP radiation leak was never supposed to happen", "Radiation Exposure Compensation System Claims to Date Summary of Claims Received by 08/15/2013 All Claims", "Securing the Bomb 2010: Securing All Nuclear Materials in Four Years", "Pakistan's nuclear bases targeted by al-Qa", Terrorists 'have attacked Pakistan nuclear sites three times', "All Stocks of Weapons-Usable Nuclear Materials Worldwide Must be Protected Against Global Terrorist Threats", "Meltdown - Definition and More from the Free Merriam-Webster Dictionary", "REPORT ON THE PRELIMINARY FACT FINDING MISSION FOLLOWING THE ACCIDENT AT THE NUCLEAR FUEL PROCESSING FACILITY IN TOKAIMURA, JAPAN", "Afrikantov OKBM Critical Test Facility Fails", "The Fukushima Daiichi Accident. [134], In terms of energy accidents, hydroelectric plants were responsible for the most fatalities, but nuclear power plant accidents rank first in terms of their economic cost, accounting for 41 percent of all property damage. For an amount of time the reactors safety system was turned off. [22][23] Estimates of eventual deaths from cancer are highly contested. The cyber attacks involved thousands of phishing emails containing malicious codes, and information was stolen.[49]. Fuel rod ejected from reactor into the reactor hall by coolant (CO, Loss of coolant and partial core meltdown due to operator errors and technical flaws. Stuxnet is a computer worm discovered in June 2010 that is believed to have been created by the United States and Israel to attack Iran's nuclear facilities. [98] Until November 1962, the vast majority of the U.S. tests were atmospheric (that is, above-ground); after the acceptance of the Partial Test Ban Treaty all testing was regulated underground, in order to prevent the dispersion of nuclear fallout.
