Nuclear Reactor Accidents In The United States
The United States Government Accountability Office reported more than 150 incidents from 2001 to 2006 of nuclear plants not performing within acceptable safety guidelines. According to a 2010 survey of energy accidents, there have been at least 56 accidents at nuclear reactors in the United States (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage). The most serious of these was the Three Mile Island accident in 1979. Davis-Besse Nuclear Power Plant has been the source of two of the top five most dangerous nuclear incidents in the United States since 1979. and Relatively few accidents have involved fatalities. Context of Nuclear Accidents Globally, there have been at least 99 (civilian and military) recorded nuclear reactor accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define majo ...

Nitric Acid
Nitric acid is an inorganic compound with the formula . It is a highly corrosive mineral acid. The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into nitrogen oxide, oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% , it is referred to as ''fuming nitric acid''. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%. Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as synthetic dyes and medicines (e.g. metronidazole). Nitric acid is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Theft Of Radioactive Material In Tammiku
The theft of radioactive material in Tammiku, often called the Tammiku nuclear accident, took place in 1994. Three brothers in Tammiku, Männiku, Saku Parish (Harju County), Estonia Estonia, officially the Republic of Estonia, is a country in Northern Europe. It is bordered to the north by the Gulf of Finland across from Finland, to the west by the Baltic Sea across from Sweden, to the south by Latvia, and to the east by Ru ..., who were scrap metal scavengers, entered a fenced area in the woods and broke into a small shed that was seemingly abandoned (after having had no success with entering a larger building inside the area), with stairs leading to an underground hall. The brothers did not know that the buildings were nuclear waste storage facilities (although there were signs at the gate, they did not see them because they had climbed over the fence elsewhere). One of the brothers, Ivan, suffered a crush injury when a drum fell onto him. The brothers placed some pieces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1996 San Juan De Dios Radiotherapy Accident
The radiotherapy accident in Costa Rica occurred within the Alcyon II radiotherapy unit at San Juan de Dios Hospital in San José, Costa Rica. It was related to a cobalt-60 source that was being used for radiotherapy in 1996. An accidental overexposure of radiotherapy patients treated during August and September 1996 was detected. During the calibration process done after the change of 60Co source on 22 August 1996, a mistake was made in calculating the dose rate, leading to severe overexposure of patients. The error of calibration was detected on 27 September 1996, after which treatments ceased. In the course of the accident, 115 patients received an overdose of radiation and 13 died of radiation-related injuries. The San Juan de Dios Hospital, located in Costa Rica, was one of the major medical facilities offering radiotherapy services in the country. In the mid-1990s, this facility introduced cobalt-60 therapy machines as a means of treating cancer. Radiotherapy is a critica ...

Tokaimura Nuclear Accident
The Tokaimura nuclear accidents refer to two nuclear related incidents near the village of Tōkai, Ibaraki, Tōkai, Ibaraki Prefecture, Japan. The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation, Power Reactor and Nuclear Fuel Development Corporation (PNC) radioactive waste bituminisation facility. Over twenty people were exposed to radiation. The second was a criticality accident at a separate fuel reprocessing facility belonging to JCO (company), Japan Nuclear Fuel Conversion Co. (JCO) on 30 September 1999 due to improper handling of liquid uranium fuel for an experimental reactor. The incident spanned approximately 20 hours and resulted in radiation exposure for 667 people and the deaths of two workers. Most of the technicians were hospitalised for serious injuries. It was determined that the accidents were due to inadequate regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samut Prakan Radiation Accident
A radiation accident occurred in Samut Prakan Province, Thailand in January–February 2000. The accident happened when an insecurely stored unlicensed cobalt-60 radiation source was recovered by scrap metal collectors who, together with a scrapyard worker, subsequently dismantled the container, unknowingly exposing themselves and others nearby to ionizing radiation. Over the following weeks, those exposed developed symptoms of radiation sickness and eventually sought medical attention. The Office of Atomic Energy for Peace (OAEP), Thailand's nuclear regulatory agency, was notified when doctors came to suspect radiation injury, some 17 days after the initial exposure. The OAEP sent an emergency response team to locate and contain the radiation source, which was estimated to have an activity of , and was eventually traced to its owner. Investigations found failure to ensure secure storage of the radiation source to be the root cause of the accident, which resulted in ten people ...

Fukushima Daiichi Nuclear Disaster
The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan, which began on 11 March 2011. The cause of the accident was the 2011 Tōhoku earthquake and tsunami, which resulted in electrical grid failure and damaged nearly all of the power plant's Emergency power system, backup energy sources. The subsequent inability to sufficiently cool reactors after shutdown compromised Primary containment, containment and resulted in the release of radioactive contamination, radioactive contaminants into the surrounding environment. The accident was rated seven (the maximum severity) on the International Nuclear Event Scale by Nuclear and Industrial Safety Agency, following a report by the JNES (Japan Nuclear Energy Safety Organization). It is regarded as the worst nuclear incident since the Chernobyl disaster in 1986, which was also rated a seven on the International Nuclear Event Scale. According to the United Nati ...

Airborne Radioactivity Increase In Europe In Autumn 2017
Airborne radioactivity was detected in Europe during autumn 2017, starting from the last days of September. The source is widely suspected to be in Russia; the Russian government, however, denies that any nuclear mishaps occurred that could have caused the radiation spike. The radioactive isotope detected was ruthenium-106; across Europe, it was found to be in small quantities (from microbecquerels to a few millibecquerels per cubic metre of air), not significant for the health of the population far away from the source. It is estimated, however, that the radiation released posed a danger to any employees or residents within several kilometers of the currently unknown source. Radioactivity detected European monitoring networks declared increased radioactivity levels in Europe, coming from Eastern Europe, in the first days of October: * the Swiss Federal Office of Public Health (FOPH) reported increase of radioactive particles of ruthenium-106 from 25 September * The Institute ...

Nyonoksa Radiation Accident
The Nyonoksa radiation accident, Arkhangelsk explosion or Nyonoksa explosion () occurred on 8 August 2019 near Nyonoksa, a village under the administrative jurisdiction of Severodvinsk, Arkhangelsk Oblast, Russian Federation. Five military and civilian specialists were killed and three (or six, depending on the source) were injured. Background Between November 2017 and 26 February 2018, Russia conducted four tests of the 9M730 Burevestnik nuclear-powered cruise missile, launched from other test sites. According to the United States intelligence community, only the flight test in November 2017 from Pankovo test site was moderately successful with all of the others ending in failure. According to Russia, none of the tests ended in failure. During recovery efforts later in 2018, Russia used three ships, one capable of handling radioactive material from the weapon nuclear core, to bring the missile tested in November 2017 from the seabed of Barents Sea back to the surface.
