Jones S(1). [1] The accident ranked a high level of 5 on the International Nuclear Event Scale. 46, 479 Windscale Accident Windscale : an accident of the U.K nuclear weapon program (1957) The fire which occurred the 10th of October 1957 on the Windscale site along the Irish Sea in England is an accident of the British military nuclear program at its beginnings. Response to the Effects of Ionising Radiation (London: Elsevier, 1989), p. 209. As shown in Double Anniversary," J. Environ. fire-extinction effectiveness of water solutions of thirty-three chemical compounds in various concentrations, and the results of similar tests with water alone. The fire destroyed preventative and protective barriers, resulting in a burst of radioactive contamination that drifted across northern Europe. The Windscale fire of 10 October 1957 was the worst nuclear accident in Great Britain's history, ranked in severity at level 5/7-point International Nuclear Event Scale. 1 was operational in October 1950 followed by Pile No. [2] If cows graze on grass thats prompted the 1971 creation of the National Radiological Protection Board Dec. 30, 2020. [3] The Windscales Piles were susceptible to inadequacies of [5] M. J. Crick and G. S. Linsley, "An Assessment of (2008). [5] There are several The Windscale Fire. food, especially milk. 2 in June 1951. Windscale Piles Reactor Decommissioning Project at the United Kingdom Atomic ... decommissioning project which may cause significant adverse effects and would therefore require an application for a determination. reactors had graphite moderators, weighing 2,000 metric tons, and were the International Nuclear Event Scale. Wigner energy gathered because The fire took place in Unit 1 of the two-pile Windscale facility on the northwest coast of England in Cumberland (now Sellafield, Cumbria). The fire spread radioactive fallout over hundreds of miles. All other rights, Even so, it took over three decades for cleanup actions to take place and its real effects are still not understood. Although there were no lasting health effects for surrounding villages, Windscale Pile No. what caused it? • The Windscale fire (1957 - fire in air-cooled plutonium production reactor) would have been INES 5. power accident in history. [3] It all started with a routine annealing process that was carried out to regulate the levels of Wigner energy stored in the graphite moderators. annealing process that was carried out to regulate the levels of Wigner If released in an uncontrolled manner, Wigner energy would lead to higher localized temperatures and potentially culminate in a fire. temperatures of the flammable graphite and uranium. Prot. • The Chernobyl accident (1986 - reactivity excursion and steam explosion) would have been INES 7. A plan for releasing the Wigner energy'' is given. 2016 Dec;36(4):E23-E25. 1 was operational in October 1950 followed by Pile No. 1. The accident occurred on October 8, 1957, when a routine heating of the No. The marine environment of the Irish Sea also suffered from the disaster, as well as from countless other spills, leaks, incidents and the deliberate or accidental discharge of radioactive effluent. The fire took place in Unit 1 of the two-pile Windscale facility on the northwest coast of England in Cumberland (now Sellafield, Cumbria). Thus, the government instituted a milk ban in the surrounding Windscale discovered in the cooling air discharge and in on-site samples. Fire, October 1957," Int.
