Windscale Fire Nuclear Disaster
Lindsay, Kayley, and Gregory
Background
Overview
*The fire happened on October 10th, 1957
*It was ranked in severity at level 5 out of a possible 7 on the International Nuclear Event Scale
*The Windscale plant consisted of two gas-cooled nuclear reactors.
*There was a routine heating of the No. 1 reactor’s graphite control blocks got out of control
*That caused adjacent uranium cartridges to rupture
Environmental Impacts
Environmental Impacts
*The marine environment of the Irish Sea also suffered
*83,000 liters of radioactive acid leaked into the North Sea
*It contributed to radioactive pollution of the Atlantic Ocean
*The land around the accident is now more vulnerable to a variety of risks
Economic Impacts
*The final cost of cleanup of the Windscale plant is estimated at 30 million dollars
*It was expected to be paid fully in 2018
*Milk produced in a 500-square-km of the accident was banned
Picture
Human Impacts
*The Windscale fire and the ensuing fallout, are estimated to have caused at least 190 cases of cancer, more than half of which were fatal.
*a single nuclear explosion can generate an intense pulse of thermal radiation that can start fires and burn skin over large areas.
* Contact with radiation from uranium can also affect your health possible health effects include lung cancer, bone cancer, and impaired function of the kidneys.
