It throws a revealing new light on an important event of fifty years ago and on questions of secrecy and responsibility. By this point, The British were brought into the fold, so to speak. On 10th October 1957, Pile 1 at Windscale in West Cumbria was on fire. that two thermometers were not even working properly. The Windscale nuclear reactor fire at Sellafield, United Kingdom, in October 1957 led to an uncontrolled release of iodine-131 (radioactive half-life, 8 d) into the atmosphere. as it should. Instead of proceeding Graphite irradiated at low temperature accumulates energy and then releases it spontaneously causing a … Each pile was housed separately in large, concrete buildings a Scientists immediately came up with three Windscale fire, accident in 1957 at the Windscale nuclear reactor facility and plutonium-production plant in the county of Cumberland (now part of Cumbria), in northwestern England, that was the United Kingdom’s most serious nuclear power accident. Updates? Omissions? The causes of the Windscale nuclear reactor fire. The atmospheric release of xenon-133 by the Fukushima Daiichi nuclear disaster was similar to that released at Chernobyl, and thus, high above what the Windscale fire released. • Windscale Pile 1 was completed in October 1950, and Pile 2 completed June 1951 © The Guardian – Permission of Sellafield Ltd. 4. the rods. Please refer to the appropriate style manual or other sources if you have any questions. There were no evacuations of the surrounding area, but it has been estimated that the incident caused 240 additional cancer cases. From the Irish famine to Lady Godiva, journey through European history in this quiz. Pile 1 and Pile 2 at Windscale had been built to make weapons-grade plutonium. There were no evacuations of the surrounding area, but it has been estimated that the incident caused 240 additional cancer cases. author. 1 reactor’s graphite control blocks got out of control, causing adjacent uranium cartridges to rupture. 1957 November 16; 2(5054): 1171–1172. Graphite moderated reactors were involved in two of the best known nuclear disasters: an untested graphite annealing process contributed to the Windscale fire (but the graphite itself did not catch fire), while a graphite fire during the Chernobyl disaster contributed to the spread of radioactive material. On October 10 1957, uranium fuel at the Windscale plant in Cumbria overheated and caught fire, setting in motion a terrifying series of events. The Manhattan At the time, the British government released only sketchy details of the accident and in general tried to minimize its seriousness. The event, generally known as the 'Windscale accident' or the 'Windscale pile fire', has been retrospectively rated at 5 on the INES scale . permission to copy, distribute and display this work in unaltered form, Upon further investigation, they [3] The Windscales Piles were susceptible to inadequacies of temperature control because of how the energy was released. On October 7, 1957, a routine heating of Windscale Pile 1 began using the Wigner approach of annealing the reactor core. In 1957, one of the two reactors built at Windscale was destroyed by fire, in the world's first major nuclear accident. Our editors will review what you’ve submitted and determine whether to revise the article. As a consequence, the government banned for several weeks the sale of milk produced in a 500-square-km (200-square-mile) area around the reactor site. This process, Shortly following the disaster, an investigation took ... 'To investigate the causes of the accident at Windscale No. This controlled heating proved successful and was AFTERMATH OF THE WINDSCALE FIRE Overall, the design of modern nuclear reactors are different today than when the Windscale fire occurred, preventing an incident like this from happening again. Windscale fire failed to acknowledge that the temperature was dropping This … Who was known as the Iron Chancellor? Windscale (Sellafield) piles facility with air-cooling discharge stacks and the ... a local fire that caused the combustion of the surrounding graphite moderator. These last two factors were the cause of the fire on the nuclear pile No. face in protective gear to secure the inspection plug. England. However instead of a gradual release of energy, the high temperature caused a buildup of energy to be stored the core. However On October 7, 1957 the Windscale Plant consisted of two gas cooled nuclear reactors. The event, generally known as the 'Windscale accident' or the 'Windscale pile fire', has been retrospectively rated at 5 on the INES scale . other rights, including commercial rights, are reserved to the The contaminated Windscale reactor was subsequently sealed until the late 1980s, when a cleanup of it was begun (cleanup expected to be completed in 2015). The Windscale Piles are pictured in Fig. Finally, shutdown fans were the water was turned off after the fires completely subsided and the 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 Windscale fire also caused the release of sizable amounts of radioactive iodine into the atmosphere. In hopes of accelerating the reactors were cold. of the core's highest temperatures causing operators to be unaware of Accident at Windscale. In 1957, a fire at the Windscale nuclear reactor in Cumbria led to a release of radioactive material that spread across the UK and Europe. Additionally, they were fueled by 180 tons of The fire left about 10 tons of radioactive fuel melted in the reactor core. Wigner process, the operators increased the power even more. placement of reactor 1's thermometers, the operators couldn't get a read unforeseen situation such as the overheating that occurred. During World War II, the Manhattan To the concern that the milk of the surrounding area could have been contaminated, it was destroyed. The causes of the Windscale nuclear reactor fire The fire started after a maintenance operation on the graphite (moderator) due to a lack of knowledge of the Wigner effect .
