<\/a><\/p>\nThe long term effects of Nuclear disasters can often spread over thousands of years. It is estimated that Chernobyl wont be\u00a0inhabited for at least another 20,000 years.<\/p>\n
Despite the threat of \u00a0Nuclear disasters, believe it or not, Nuclear Power Plants are prominent and provide approximately 5.7% of the world\u2019s energy and 13% of the world\u2019s electricity.<\/p>\n
With 437 Nuclear Power Plants worldwide, there are bound to be incidents every now and again. Small incidents occur and can be rectified, but when there are large incidents, the impact can often be catastrophic.<\/p>\n
Each Nuclear disaster has been given a level on the International Nuclear Event Scale<\/span><\/a><\/span> (INES).<\/p>\n Click on the header of each nuclear disaster for a detailed look at each event.<\/p>\n Process Industry Forum<\/a>\u00a0have scrawled the web and created a Top 10 for the worst Nuclear disasters of all time:<\/p>\n When a group of unqualified workers decided to put more highly enriched uranium in a precipitation tank than was permitted, disaster struck. Two of the workers eventually died with another fifty six plant workers also being exposed to high levels of radiation. To make matters worse, 21 civilians were also exposed to high doses of radiation and residents within a thousand feet of the plant were evacuated.<\/p>\n An operator\u2019s errors during a fuel plate reconfiguration lead to him dying two days later. There was an excursion of 3×10 fissions at the RA-2 facility with the operator absorbing 2000 rad of gamma and 1700 rad of neutron radiation. Another 17 people outside of the reactor room absorbed doses ranging from 35 rad to less than 1 rad.<\/p>\n On the 17th<\/sup>\u00a0October, 1969 50 kg\u00a0of uranium in one of the gas cooled reactors began to melt. This was classified as Level 4 on the INES and to this day remains the most serious civil Nuclear disaster in French history.<\/p>\n On 3rd\u00a0January, 1961 a USA army experimental nuclear power reactor underwent a steam explosion and meltdown killing its three operators. The cause of this was because of improper removal of the control rod, responsible for absorbing neutrons in the reactor core. This event is the only known fatal reactor accident in the USA. The accident released about 80 curies of iodine -131.<\/p>\n On 13th\u00a0September, 1987 a radioactive contamination accident occurred in the Brazilian state of Goais. An old radiotherapy source was stolen from an abandoned hospital site in the city. Subsequently it was handled by many people, killing four people. 112,000 people were examined for radioactive\u00a0contamination’s\u00a0with 249 having significant levels of radioactive material in or on their body.<\/p>\n 28th<\/sup>\u00a0March saw two nuclear reactors meltdown. It was subsequently the worst disaster in commercial nuclear power plant history. Small amounts of radioactive gases and radioactive iodine were released into the environment. Luckily, epidemiology studies have not linked a single cancer with the accident.<\/p>\n The worst nuclear disaster in Great Britain\u2019s history occurred on the 10th<\/sup>\u00a0October, 1957 and ranked at level 5 on the INES scale,\u00a0The Windscale Fire<\/span><\/a><\/span>. The two piles had been hurriedly built as part of the British atomic bomb project. The first pile was active from October 1950 with the second close behind in June 1951. The accident occurred when the core of Unit 1\u2019s reactor caught fire, releasing substantial amounts of radioactive contamination into the surrounding area. 240 cancer cases have since been linked to the fire. All of the milk from within about 500km of nearby countryside was diluted and destroyed for about a month.<\/p>\n The\u00a0Kyshtym Nuclear disaster\u00a0was a radiation contamination incident that occurred on 29 September 1957 at Mayak, a Nuclear fuel reprocessing plant\u00a0in the Soviet Union. It measured as a Level 6 disaster on the INES, making it the third most serious Nuclear disaster ever recorded behind the Chernobyl Disaster and Fukushima Daiichi Disaster. The event occurred in the town of Ozyorsk, a closed city\u00a0built around the Mayak\u00a0plant. Since Ozyorsk\/Mayak was not marked on maps, the disaster was named after Kyshtym, the nearest known town.<\/p>\n The\u00a0Fukushima Daiichi nuclear disaster<\/span><\/a><\/span>\u00a0was a series of equipment failures, nuclear meltdowns\u00a0and releases of radioactive\u00a0materials at the Fukushima, Nuclear Power Plant, following the Tohoku Tsunami\u00a0on 11 March, 2011. \u00a0It is the largest nuclear disaster since the Chernobyl disaster\u00a0of 1986 and only the second disaster (along with Chernobyl) to measure Level 7 on the INES.<\/p>\n The Chernoby<\/span><\/a>l<\/span>\u00a0Nuclear disaster is widely considered to have been the worst\u00a0power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale\u00a0(the other being the Fukushima, Daiichi disaster\u00a0in 2011).\u00a0The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18\u00a0billion rubles. \u00a0The official Soviet casualty count of 31 deaths has been disputed and long-term effects such as cancers and deformities are still being accounted for.<\/p>\n<\/a><\/p>\n10.
